In particular, +it restores binary ABI compatibility with release version 2.0. +The deprecated "google" namespace is by default still kept as +primary namespace while symbols are imported into the new "gflags" namespace. +This can be overridden using the CMake variable GFLAGS_NAMESPACE. + +Other fixes of the build configuration are related to the (patched) +CMake modules FindThreads.cmake and CheckTypeSize.cmake. These have +been removed and instead the C language is enabled again even though +gflags is written in C++ only. + +This release also marks the complete move of the gflags project +from Google Code to GitHub. Email addresses of original issue +reporters got lost in the process. Given the age of most issue reports, +this should be negligable. + +Please report any further issues using the GitHub issue tracker. + + +30 March 2014 +------------- + +I've just released gflags 2.1.1. + +This release fixes a few bugs in the configuration of gflags\_declare.h +and adds a separate GFLAGS\_INCLUDE\_DIR CMake variable to the build configuration. +Setting GFLAGS\_NAMESPACE to "google" no longer changes also the include +path of the public header files. This allows the use of the library with +other Google projects such as glog which still use the deprecated "google" +namespace for the gflags library, but include it as "gflags/gflags.h". + +20 March 2014 +------------- + +I've just released gflags 2.1. + +The major changes are the use of CMake for the build configuration instead +of the autotools and packaging support through CPack. The default namespace +of all C++ symbols is now "gflags" instead of "google". This can be +configured via the GFLAGS\_NAMESPACE variable. + +This release compiles with all major compilers without warnings and passed +the unit tests on Ubuntu 12.04, Windows 7 (Visual Studio 2008 and 2010, +Cygwin, MinGW), and Mac OS X (Xcode 5.1). + +The SVN repository on Google Code is now frozen and replaced by a Git +repository such that it can be used as Git submodule by projects. The main +hosting of this project remains at Google Code. Thanks to the distributed +character of Git, I can push (and pull) changes from both GitHub and Google Code +in order to keep the two public repositories in sync. +When fixing an issue for a pull request through either of these hosting +platforms, please reference the issue number as +[described here](https://code.google.com/p/support/wiki/IssueTracker#Integration_with_version_control). +For the further development, I am following the +[Git branching model](http://nvie.com/posts/a-successful-git-branching-model/) +with feature branch names prefixed by "feature/" and bugfix branch names +prefixed by "bugfix/", respectively. + +Binary and source [packages](https://github.com/schuhschuh/gflags/releases) are available on GitHub. + + +14 January 2014 +--------------- + +The migration of the build system to CMake is almost complete. +What remains to be done is rewriting the tests in Python such they can be +executed on non-Unix platforms and splitting them up into separate CTest tests. +Though merging these changes into the master branch yet remains to be done, +it is recommended to already start using the +[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) branch. + + +20 April 2013 +------------- + +More than a year has past since I (Andreas) took over the maintenance for +`gflags`. Only few minor changes have been made since then, much to my regret. +To get more involved and stimulate participation in the further +development of the library, I moved the project source code today to +[GitHub](https://github.com/schuhschuh/gflags). +I believe that the strengths of [Git](http://git-scm.com/) will allow for better community collaboration +as well as ease the integration of changes made by others. I encourage everyone +who would like to contribute to send me pull requests. +Git's lightweight feature branches will also provide the right tool for more +radical changes which should only be merged back into the master branch +after these are complete and implement the desired behavior. + +The SVN repository remains accessible at Google Code and I will keep the +master branch of the Git repository hosted at GitHub and the trunk of the +Subversion repository synchronized. Initially, I was going to simply switch the +Google Code project to Git, but in this case the SVN repository would be +frozen and force everyone who would like the latest development changes to +use Git as well. Therefore I decided to host the public Git repository at GitHub +instead. + +Please continue to report any issues with gflags on Google Code. The GitHub project will +only be used to host the Git repository. + +One major change of the project structure I have in mind for the next weeks +is the migration from autotools to [CMake](http://www.cmake.org/). +Check out the (unstable!) +[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) +branch on GitHub for details. + + +25 January 2012 +--------------- + +I've just released gflags 2.0. + +The `google-gflags` project has been renamed to `gflags`. I +(csilvers) am stepping down as maintainer, to be replaced by Andreas +Schuh. Welcome to the team, Andreas! I've seen the energy you have +around gflags and the ideas you have for the project going forward, +and look forward to having you on the team. + +I bumped the major version number up to 2 to reflect the new community +ownership of the project. All the [changes](ChangeLog.txt) +are related to the renaming. There are no functional changes from +gflags 1.7. In particular, I've kept the code in the namespace +`google`, though in a future version it should be renamed to `gflags`. +I've also kept the `/usr/local/include/google/` subdirectory as +synonym of `/usr/local/include/gflags/`, though the former name has +been obsolete for some time now. + + +18 January 2011 +--------------- + +The `google-gflags` Google Code page has been renamed to +`gflags`, in preparation for the project being renamed to +`gflags`. In the coming weeks, I'll be stepping down as +maintainer for the gflags project, and as part of that Google is +relinquishing ownership of the project; it will now be entirely +community run. The name change reflects that shift. + + +20 December 2011 +---------------- + +I've just released gflags 1.7. This is a minor release; the major +change is that `CommandLineFlagInfo` now exports the address in memory +where the flag is located. There has also been a bugfix involving +very long --help strings, and some other minor [changes](ChangeLog.txt). + +29 July 2011 +------------ + +I've just released gflags 1.6. The major new feature in this release +is support for setting version info, so that --version does something +useful. + +One minor change has required bumping the library number: +`ReparseCommandlineFlags` now returns `void` instead of `int` (the int +return value was always meaningless). Though I doubt anyone ever used +this (meaningless) return value, technically it's a change to the ABI +that requires a version bump. A bit sad. + +There's also a procedural change with this release: I've changed the +internal tools used to integrate Google-supplied patches for gflags +into the opensource release. These new tools should result in more +frequent updates with better change descriptions. They will also +result in future `ChangeLog` entries being much more verbose (for better +or for worse). + +See the [ChangeLog](ChangeLog.txt) for a full list of changes for this release. + +24 January 2011 +--------------- + +I've just released gflags 1.5. This release has only minor changes +from 1.4, including some slightly better reporting in --help, and +an new memory-cleanup function that can help when running gflags-using +libraries under valgrind. The major change is to fix up the macros +(`DEFINE_bool` and the like) to work more reliably inside namespaces. + +If you have not had a problem with these macros, and don't need any of +the other changes described, there is no need to upgrade. See the +[ChangeLog](ChangeLog.txt) for a full list of changes for this release. + +11 October 2010 +--------------- + +I've just released gflags 1.4. This release has only minor changes +from 1.3, including some documentation tweaks and some work to make +the library smaller. If 1.3 is working well for you, there's no +particular reason to upgrade. + +4 January 2010 +-------------- + +I've just released gflags 1.3. gflags now compiles under MSVC, and +all tests pass. I **really** never thought non-unix-y Windows folks +would want gflags, but at least some of them do. + +The major news, though, is that I've separated out the python package +into its own library, [python-gflags](http://code.google.com/p/python-gflags). +If you're interested in the Python version of gflags, that's the place to +get it now. + +10 September 2009 +----------------- + +I've just released gflags 1.2. The major change from gflags 1.1 is it +now compiles under MinGW (as well as cygwin), and all tests pass. I +never thought Windows folks would want unix-style command-line flags, +since they're so different from the Windows style, but I guess I was +wrong! + +The other changes are minor, such as support for --htmlxml in the +python version of gflags. + +15 April 2009 +------------- + +I've just released gflags 1.1. It has only minor changes fdrom gflags +1.0 (see the [ChangeLog](ChangeLog.txt) for details). +The major change is that I moved to a new system for creating .deb and .rpm files. +This allows me to create x86\_64 deb and rpm files. + +In the process of moving to this new system, I noticed an +inconsistency: the tar.gz and .rpm files created libraries named +libgflags.so, but the deb file created libgoogle-gflags.so. I have +fixed the deb file to create libraries like the others. I'm no expert +in debian packaging, but I believe this has caused the package name to +change as well. Please let me know (at +[[mailto:google-gflags@googlegroups.com](mailto:google-gflags@googlegroups.com) +google-gflags@googlegroups.com]) if this causes problems for you -- +especially if you know of a fix! I would be happy to change the deb +packages to add symlinks from the old library name to the new +(libgoogle-gflags.so -> libgflags.so), but that is beyond my knowledge +of how to make .debs. + +If you've tried to install a .rpm or .deb and it doesn't work for you, +let me know. I'm excited to finally have 64-bit package files, but +there may still be some wrinkles in the new system to iron out. + +1 October 2008 +-------------- + +gflags 1.0rc2 was out for a few weeks without any issues, so gflags +1.0 is now released. This is much like gflags 0.9. The major change +is that the .h files have been moved from `/usr/include/google` to +`/usr/include/gflags`. While I have backwards-compatibility +forwarding headeds in place, please rewrite existing code to say +``` + #include +``` +instead of +``` + #include +``` + +I've kept the default namespace to google. You can still change with +with the appropriate flag to the configure script (`./configure +--help` to see the flags). If you have feedback as to whether the +default namespace should change to gflags, which would be a +non-backwards-compatible change, send mail to +`google-gflags@googlegroups.com`! + +Version 1.0 also has some neat new features, like support for bash +commandline-completion of help flags. See the [ChangeLog](ChangeLog.txt) +for more details. + +If I don't hear any bad news for a few weeks, I'll release 1.0-final. diff --git a/3rdparty/gflags-2.2.0/WORKSPACE b/3rdparty/gflags-2.2.0/WORKSPACE new file mode 100644 index 000000000..f3707e906 --- /dev/null +++ b/3rdparty/gflags-2.2.0/WORKSPACE @@ -0,0 +1,6 @@ +# Copyright 2006 Google Inc.

Here's how everything fits together +// +// * FlagRegistry owns CommandLineFlags owns FlagValue. +// * FlagSaver holds a FlagRegistry (saves it at construct time, +// restores it at destroy time). +// * CommandLineFlagParser lives outside that hierarchy, but works on +// CommandLineFlags (modifying the FlagValues). +// * Free functions like SetCommandLineOption() work via one of the +// above (such as CommandLineFlagParser). +// +// In more detail: +// +// -- The main classes that hold flag data: +// +// FlagValue holds the current value of a flag. It's +// pseudo-templatized: every operation on a FlagValue is typed. It +// also deals with storage-lifetime issues (so flag values don't go +// away in a destructor), which is why we need a whole class to hold a +// variable's value. +// +// CommandLineFlag is all the information about a single command-line +// flag. It has a FlagValue for the flag's current value, but also +// the flag's name, type, etc. +// +// FlagRegistry is a collection of CommandLineFlags. There's the +// global registry, which is where flags defined via DEFINE_foo() +// live. But it's possible to define your own flag, manually, in a +// different registry you create. (In practice, multiple registries +// are used only by FlagSaver). +// +// A given FlagValue is owned by exactly one CommandLineFlag. A given +// CommandLineFlag is owned by exactly one FlagRegistry. FlagRegistry +// has a lock; any operation that writes to a FlagValue or +// CommandLineFlag owned by that registry must acquire the +// FlagRegistry lock before doing so. +// +// --- Some other classes and free functions: +// +// CommandLineFlagInfo is a client-exposed version of CommandLineFlag. +// Once it's instantiated, it has no dependencies or relationships +// with any other part of this file. +// +// FlagRegisterer is the helper class used by the DEFINE_* macros to +// allow work to be done at global initialization time. +// +// CommandLineFlagParser is the class that reads from the commandline +// and instantiates flag values based on that. It needs to poke into +// the innards of the FlagValue->CommandLineFlag->FlagRegistry class +// hierarchy to do that. It's careful to acquire the FlagRegistry +// lock before doing any writing or other non-const actions. +// +// GetCommandLineOption is just a hook into registry routines to +// retrieve a flag based on its name. SetCommandLineOption, on the +// other hand, hooks into CommandLineFlagParser.

If this +// flag is empty, nothing happens here. If it contains a string, +// however, then HandleCommandLineCompletions() will hijack the +// process, attempting to identify the intention behind this +// completion. Regardless of the outcome of this deduction, the +// process will be terminated, similar to --helpshort flag +// handling. +// +// ** Overview of Bash completions: +// Bash can be told to programatically determine completions for the +// current 'cursor word'. It does this by (in this case) invoking a +// command with some additional arguments identifying the command +// being executed, the word being completed, and the previous word +// (if any). Bash then expects a sequence of output lines to be +// printed to stdout. If these lines all contain a common prefix +// longer than the cursor word, bash will replace the cursor word +// with that common prefix, and display nothing. If there isn't such +// a common prefix, bash will display the lines in pages using 'more'. +// +// ** Strategy taken for command line completions: +// If we can deduce either the exact flag intended, or a common flag +// prefix, we'll output exactly that. Otherwise, if information +// must be displayed to the user, we'll take the opportunity to add +// some helpful information beyond just the flag name (specifically, +// we'll include the default flag value and as much of the flag's +// description as can fit on a single terminal line width, as specified +// by the flag --tab_completion_columns). Furthermore, we'll try to +// make bash order the output such that the most useful or relevent +// flags are the most likely to be shown at the top. +// +// ** Additional features: +// To assist in finding that one really useful flag, substring matching +// was implemented. Before pressing a to get completion for the +// current word, you can append one or more '?' to the flag to do +// substring matching. Here's the semantics: +// --foo Show me all flags with names prefixed by 'foo' +// --foo? Show me all flags with 'foo' somewhere in the name +// --foo?? Same as prior case, but also search in module +// definition path for 'foo' +// --foo??? Same as prior case, but also search in flag +// descriptions for 'foo' +// Finally, we'll trim the output to a relatively small number of +// flags to keep bash quiet about the verbosity of output. If one +// really wanted to see all possible matches, appending a '+' to the +// search word will force the exhaustive list of matches to be printed. +// +// ** How to have bash accept completions from a binary: +// Bash requires that it be informed about each command that programmatic +// completion should be enabled for. Example addition to a .bashrc +// file would be (your path to gflags_completions.sh file may differ): + +/* +$ complete -o bashdefault -o default -o nospace -C \ + '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \ + time env binary_name another_binary [...] +*/ + +// This would allow the following to work: +// $ /path/to/binary_name --vmodule +// Or: +// $ ./bin/path/another_binary --gfs_u +// (etc) +// +// Sadly, it appears that bash gives no easy way to force this behavior for +// all commands.

Before you use this module, please give the +// name of your internal namespace for this module. Or, if you want +// to expose it, you'll want to move it to the Google namespace. We +// cannot put this class in global namespace because there can be some +// problems when we have multiple versions of Mutex in each shared object. +// +// NOTE: by default, we have #ifdef'ed out the TryLock() method. +// This is for two reasons: +// 1) TryLock() under Windows is a bit annoying (it requires a +// #define to be defined very early). +// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG +// mode. +// If you need TryLock(), and either these two caveats are not a +// problem for you, or you're willing to work around them, then +// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs +// in the code below. +// +// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: +// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html +// Because of that, we might as well use windows locks for +// cygwin. They seem to be more reliable than the cygwin pthreads layer. +// +// TRICKY IMPLEMENTATION NOTE: +// This class is designed to be safe to use during +// dynamic-initialization -- that is, by global constructors that are +// run before main() starts. The issue in this case is that +// dynamic-initialization happens in an unpredictable order, and it +// could be that someone else's dynamic initializer could call a +// function that tries to acquire this mutex -- but that all happens +// before this mutex's constructor has run. (This can happen even if +// the mutex and the function that uses the mutex are in the same .cc +// file.) Basically, because Mutex does non-trivial work in its +// constructor, it's not, in the naive implementation, safe to use +// before dynamic initialization has run on it. +// +// The solution used here is to pair the actual mutex primitive with a +// bool that is set to true when the mutex is dynamically initialized. +// (Before that it's false.) Then we modify all mutex routines to +// look at the bool, and not try to lock/unlock until the bool makes +// it to true (which happens after the Mutex constructor has run.) +// +// This works because before main() starts -- particularly, during +// dynamic initialization -- there are no threads, so a) it's ok that +// the mutex operations are a no-op, since we don't need locking then +// anyway; and b) we can be quite confident our bool won't change +// state between a call to Lock() and a call to Unlock() (that would +// require a global constructor in one translation unit to call Lock() +// and another global constructor in another translation unit to call +// Unlock() later, which is pretty perverse). +// +// That said, it's tricky, and can conceivably fail; it's safest to +// avoid trying to acquire a mutex in a global constructor, if you +// can. One way it can fail is that a really smart compiler might +// initialize the bool to true at static-initialization time (too +// early) rather than at dynamic-initialization time. To discourage +// that, we set is_safe_ to true in code (not the constructor +// colon-initializer) and set it to true via a function that always +// evaluates to true, but that the compiler can't know always +// evaluates to true. This should be good enough. +// +// A related issue is code that could try to access the mutex +// after it's been destroyed in the global destructors (because +// the Mutex global destructor runs before some other global +// destructor, that tries to acquire the mutex). The way we +// deal with this is by taking a constructor arg that global +// mutexes should pass in, that causes the destructor to do no +// work. We still depend on the compiler not doing anything +// weird to a Mutex's memory after it is destroyed, but for a +// static global variable, that's pretty safe. + +#ifndef GFLAGS_MUTEX_H_ +#define GFLAGS_MUTEX_H_ + +#include "gflags/gflags_declare.h" // to figure out pthreads support + +#if defined(NO_THREADS) + typedef int MutexType; // to keep a lock-count +#elif defined(OS_WINDOWS) +# ifndef WIN32_LEAN_AND_MEAN +# define WIN32_LEAN_AND_MEAN // We only need minimal includes +# endif +# ifndef NOMINMAX +# define NOMINMAX // Don't want windows to override min()/max() +# endif +# ifdef GMUTEX_TRYLOCK + // We need Windows NT or later for TryEnterCriticalSection().

(In particular, if you are using +InstallFailureSignalHandler(), the signal may be raised in the middle +of malloc, holding some malloc-related locks when they invoke the +stack unwinder. The built-in stack unwinder may call malloc +recursively, which may require the thread to acquire a lock it already +holds: deadlock.) + +For that reason, if you use a 64-bit system and you need +InstallFailureSignalHandler(), we strongly recommend you install +libunwind before trying to configure or install google glog. +libunwind can be found at + + http://download.savannah.nongnu.org/releases/libunwind/libunwind-snap-070410.tar.gz + +Even if you already have libunwind installed, you will probably still +need to install from the snapshot to get the latest version. + +CAUTION: if you install libunwind from the URL above, be aware that +you may have trouble if you try to statically link your binary with +glog: that is, if you link with 'gcc -static -lgcc_eh ...'. This +is because both libunwind and libgcc implement the same C++ exception +handling APIs, but they implement them differently on some platforms. +This is not likely to be a problem on ia64, but may be on x86-64. + +Also, if you link binaries statically, make sure that you add +-Wl,--eh-frame-hdr to your linker options. This is required so that +libunwind can find the information generated by the compiler required +for stack unwinding. + +Using -static is rare, though, so unless you know this will affect you +it probably won't. + +If you cannot or do not wish to install libunwind, you can still try +to use two kinds of stack-unwinder: 1. glibc built-in stack-unwinder +and 2. frame pointer based stack-unwinder. + +1. As we already mentioned, glibc's unwinder has a deadlock issue. +However, if you don't use InstallFailureSignalHandler() or you don't +worry about the rare possibilities of deadlocks, you can use this +stack-unwinder. If you specify no options and libunwind isn't +detected on your system, the configure script chooses this unwinder by +default. + +2. The frame pointer based stack unwinder requires that your +application, the glog library, and system libraries like libc, all be +compiled with a frame pointer. This is *not* the default for x86-64. + +If you are on x86-64 system, know that you have a set of system +libraries with frame-pointers enabled, and compile all your +applications with -fno-omit-frame-pointer, then you can enable the +frame pointer based stack unwinder by passing the +--enable-frame-pointers flag to configure. + + +Basic Installation +================== + +Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/3rdparty/glog-0.3.4/Makefile.am b/3rdparty/glog-0.3.4/Makefile.am new file mode 100644 index 000000000..3756465fe --- /dev/null +++ b/3rdparty/glog-0.3.4/Makefile.am @@ -0,0 +1,249 @@ +## Process this file with automake to produce Makefile.in + +AUTOMAKE_OPTIONS=subdir-objects + +# Make sure that when we re-make ./configure, we get the macros we need +ACLOCAL_AMFLAGS = -I m4 + +# This is so we can #include +AM_CPPFLAGS = -I$(top_srcdir)/src + +# This is mostly based on configure options +AM_CXXFLAGS = + +# These are good warnings to turn on by default +if GCC + AM_CXXFLAGS += -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare +endif + +# These are x86-specific, having to do with frame-pointers +if X86_64 +if ENABLE_FRAME_POINTERS + AM_CXXFLAGS += -fno-omit-frame-pointer +else + # TODO(csilvers): check if -fomit-frame-pointer might be in $(CXXFLAGS), + # before setting this. + AM_CXXFLAGS += -DNO_FRAME_POINTER +endif +endif + +if DISABLE_RTTI + AM_CXXFLAGS += -fno-rtti +endif + +glogincludedir = $(includedir)/glog +## The .h files you want to install (that is, .h files that people +## who install this package can include in their own applications.) +## We have to include both the .h and .h.in forms.

How To Use Google Logging Library (glog)

+(as of +) + +
+ +

Introduction

+ +

Google glog is a library that implements application-level +logging. This library provides logging APIs based on C++-style +streams and various helper macros. +You can log a message by simply streaming things to LOG(<a +particular severity level>), e.g. + +

+   #include <glog/logging.h>
+
+   int main(int argc, char* argv[]) {
+     // Initialize Google's logging library.
+     google::InitGoogleLogging(argv[0]);
+
+     // ...
+     LOG(INFO) << "Found " << num_cookies << " cookies";
+   }
+
+ +

Google glog defines a series of macros that simplify many common logging +tasks. You can log messages by severity level, control logging +behavior from the command line, log based on conditionals, abort the +program when expected conditions are not met, introduce your own +verbose logging levels, and more. This document describes the +functionality supported by glog. Please note that this document +doesn't describe all features in this library, but the most useful +ones. If you want to find less common features, please check +header files under src/glog directory. + +

Severity Level

+ +

+You can specify one of the following severity levels (in +increasing order of severity): INFO, WARNING, +ERROR, and FATAL. +Logging a FATAL message terminates the program (after the +message is logged). +Note that messages of a given severity are logged not only in the +logfile for that severity, but also in all logfiles of lower severity. +E.g., a message of severity FATAL will be logged to the +logfiles of severity FATAL, ERROR, +WARNING, and INFO. + +

+The DFATAL severity logs a FATAL error in +debug mode (i.e., there is no NDEBUG macro defined), but +avoids halting the program in production by automatically reducing the +severity to ERROR. + +

Unless otherwise specified, glog writes to the filename +"/tmp/<program name>.<hostname>.<user name>.log.<severity level>.<date>.<time>.<pid>" +(e.g., "/tmp/hello_world.example.com.hamaji.log.INFO.20080709-222411.10474"). +By default, glog copies the log messages of severity level +ERROR or FATAL to standard error (stderr) +in addition to log files. + +

Setting Flags

+ +

Several flags influence glog's output behavior. +If the Google +gflags library is installed on your machine, the +configure script (see the INSTALL file in the package for +detail of this script) will automatically detect and use it, +allowing you to pass flags on the command line. For example, if you +want to turn the flag --logtostderr on, you can start +your application with the following command line: + +

+   ./your_application --logtostderr=1
+
+ +If the Google gflags library isn't installed, you set flags via +environment variables, prefixing the flag name with "GLOG_", e.g. + +
+   GLOG_logtostderr=1 ./your_application
+
+ + + +

The following flags are most commonly used: + +

+
logtostderr (bool, default=false) +
Log messages to stderr instead of logfiles.
+Note: you can set binary flags to true by specifying +1, true, or yes (case +insensitive). +Also, you can set binary flags to false by specifying +0, false, or no (again, case +insensitive). +
stderrthreshold (int, default=2, which +is ERROR) +
Copy log messages at or above this level to stderr in +addition to logfiles. The numbers of severity levels +INFO, WARNING, ERROR, and +FATAL are 0, 1, 2, and 3, respectively. +
minloglevel (int, default=0, which +is INFO) +
Log messages at or above this level. Again, the numbers of +severity levels INFO, WARNING, +ERROR, and FATAL are 0, 1, 2, and 3, +respectively. +
log_dir (string, default="") +
If specified, logfiles are written into this directory instead +of the default logging directory. +
v (int, default=0) +
Show all VLOG(m) messages for m less or +equal the value of this flag. Overridable by --vmodule. +See the section about verbose logging for more +detail. +
vmodule (string, default="") +
Per-module verbose level. The argument has to contain a +comma-separated list of <module name>=<log level>. +<module name> +is a glob pattern (e.g., gfs* for all modules whose name +starts with "gfs"), matched against the filename base +(that is, name ignoring .cc/.h./-inl.h). +<log level> overrides any value given by --v. +See also the section about verbose logging. +
+ +

There are some other flags defined in logging.cc. Please grep the +source code for "DEFINE_" to see a complete list of all flags. + +

You can also modify flag values in your program by modifying global +variables FLAGS_* . Most settings start working +immediately after you update FLAGS_* . The exceptions are +the flags related to destination files. For example, you might want to +set FLAGS_log_dir before +calling google::InitGoogleLogging . Here is an example: + +

+   LOG(INFO) << "file";
+   // Most flags work immediately after updating values.
+   FLAGS_logtostderr = 1;
+   LOG(INFO) << "stderr";
+   FLAGS_logtostderr = 0;
+   // This won't change the log destination. If you want to set this
+   // value, you should do this before google::InitGoogleLogging .
+   FLAGS_log_dir = "/some/log/directory";
+   LOG(INFO) << "the same file";
+
+ +

Conditional / Occasional Logging

+ +

Sometimes, you may only want to log a message under certain +conditions. You can use the following macros to perform conditional +logging: + +

+   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+
+ +The "Got lots of cookies" message is logged only when the variable +num_cookies exceeds 10. + +If a line of code is executed many times, it may be useful to only log +a message at certain intervals. This kind of logging is most useful +for informational messages. + +
+   LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
+
+ +

The above line outputs a log messages on the 1st, 11th, +21st, ... times it is executed. Note that the special +google::COUNTER value is used to identify which repetition is +happening. + +

You can combine conditional and occasional logging with the +following macro. + +

+   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
+                                           << "th big cookie";
+
+ +

Instead of outputting a message every nth time, you can also limit +the output to the first n occurrences: + +

+   LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
+
+ +

Outputs log messages for the first 20 times it is executed. Again, +the google::COUNTER identifier indicates which repetition is +happening. + +

Debug Mode Support

+ +

Special "debug mode" logging macros only have an effect in debug +mode and are compiled away to nothing for non-debug mode +compiles. Use these macros to avoid slowing down your production +application due to excessive logging. + +

+   DLOG(INFO) << "Found cookies";
+
+   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+
+   DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
+
+ +

CHECK Macros

+ +

It is a good practice to check expected conditions in your program +frequently to detect errors as early as possible. The +CHECK macro provides the ability to abort the application +when a condition is not met, similar to the assert macro +defined in the standard C library. + +

CHECK aborts the application if a condition is not +true. Unlike assert, it is *not* controlled by +NDEBUG, so the check will be executed regardless of +compilation mode. Therefore, fp->Write(x) in the +following example is always executed: + +

+   CHECK(fp->Write(x) == 4) << "Write failed!";
+
+ +

There are various helper macros for +equality/inequality checks - CHECK_EQ, +CHECK_NE, CHECK_LE, CHECK_LT, +CHECK_GE, and CHECK_GT. +They compare two values, and log a +FATAL message including the two values when the result is +not as expected. The values must have operator<<(ostream, +...) defined. + +

You may append to the error message like so: + +

+   CHECK_NE(1, 2) << ": The world must be ending!";
+
+ +

We are very careful to ensure that each argument is evaluated exactly +once, and that anything which is legal to pass as a function argument is +legal here. In particular, the arguments may be temporary expressions +which will end up being destroyed at the end of the apparent statement, +for example: + +

+   CHECK_EQ(string("abc")[1], 'b');
+
+ +

The compiler reports an error if one of the arguments is a +pointer and the other is NULL. To work around this, simply static_cast +NULL to the type of the desired pointer. + +

+   CHECK_EQ(some_ptr, static_cast<SomeType*>(NULL));
+
+ +

Better yet, use the CHECK_NOTNULL macro: + +

+   CHECK_NOTNULL(some_ptr);
+   some_ptr->DoSomething();
+
+ +

Since this macro returns the given pointer, this is very useful in +constructor initializer lists. + +

+   struct S {
+     S(Something* ptr) : ptr_(CHECK_NOTNULL(ptr)) {}
+     Something* ptr_;
+   };
+
+ +

Note that you cannot use this macro as a C++ stream due to this +feature. Please use CHECK_EQ described above to log a +custom message before aborting the application. + +

If you are comparing C strings (char *), a handy set of macros +performs case sensitive as well as case insensitive comparisons - +CHECK_STREQ, CHECK_STRNE, +CHECK_STRCASEEQ, and CHECK_STRCASENE. The +CASE versions are case-insensitive. You can safely pass NULL +pointers for this macro. They treat NULL and any +non-NULL string as not equal. Two NULLs are +equal. + +

Note that both arguments may be temporary strings which are +destructed at the end of the current "full expression" +(e.g., CHECK_STREQ(Foo().c_str(), Bar().c_str()) where +Foo and Bar return C++'s +std::string). + +

The CHECK_DOUBLE_EQ macro checks the equality of two +floating point values, accepting a small error margin. +CHECK_NEAR accepts a third floating point argument, which +specifies the acceptable error margin. + +

Verbose Logging

+ +

When you are chasing difficult bugs, thorough log messages are very +useful. However, you may want to ignore too verbose messages in usual +development. For such verbose logging, glog provides the +VLOG macro, which allows you to define your own numeric +logging levels. The --v command line option controls +which verbose messages are logged: + +

+   VLOG(1) << "I'm printed when you run the program with --v=1 or higher";
+   VLOG(2) << "I'm printed when you run the program with --v=2 or higher";
+
+ +

With VLOG, the lower the verbose level, the more +likely messages are to be logged. For example, if +--v==1, VLOG(1) will log, but +VLOG(2) will not log. This is opposite of the severity +level, where INFO is 0, and ERROR is 2. +--minloglevel of 1 will log WARNING and +above. Though you can specify any integers for both VLOG +macro and --v flag, the common values for them are small +positive integers. For example, if you write VLOG(0), +you should specify --v=-1 or lower to silence it. This +is less useful since we may not want verbose logs by default in most +cases. The VLOG macros always log at the +INFO log level (when they log at all). + +

Verbose logging can be controlled from the command line on a +per-module basis: + +

+   --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
+
+ +

will: + +

    +
  • a. Print VLOG(2) and lower messages from mapreduce.{h,cc} +
  • b. Print VLOG(1) and lower messages from file.{h,cc} +
  • c. Print VLOG(3) and lower messages from files prefixed with "gfs" +
  • d. Print VLOG(0) and lower messages from elsewhere +
+ +

The wildcarding functionality shown by (c) supports both '*' +(matches 0 or more characters) and '?' (matches any single character) +wildcards. Please also check the section about command line flags. + +

There's also VLOG_IS_ON(n) "verbose level" condition +macro. This macro returns true when the --v is equal or +greater than n. To be used as + +

+   if (VLOG_IS_ON(2)) {
+     // do some logging preparation and logging
+     // that can't be accomplished with just VLOG(2) << ...;
+   }
+
+ +

Verbose level condition macros VLOG_IF, +VLOG_EVERY_N and VLOG_IF_EVERY_N behave +analogous to LOG_IF, LOG_EVERY_N, +LOF_IF_EVERY, but accept a numeric verbosity level as +opposed to a severity level. + +

+   VLOG_IF(1, (size > 1024))
+      << "I'm printed when size is more than 1024 and when you run the "
+         "program with --v=1 or more";
+   VLOG_EVERY_N(1, 10)
+      << "I'm printed every 10th occurrence, and when you run the program "
+         "with --v=1 or more. Present occurence is " << google::COUNTER;
+   VLOG_IF_EVERY_N(1, (size > 1024), 10)
+      << "I'm printed on every 10th occurence of case when size is more "
+         " than 1024, when you run the program with --v=1 or more. ";
+         "Present occurence is " << google::COUNTER;
+
+ +

Failure Signal Handler

+ +

+The library provides a convenient signal handler that will dump useful +information when the program crashes on certain signals such as SIGSEGV. +The signal handler can be installed by +google::InstallFailureSignalHandler(). The following is an example of output +from the signal handler. + +

+*** Aborted at 1225095260 (unix time) try "date -d @1225095260" if you are using GNU date ***
+*** SIGSEGV (@0x0) received by PID 17711 (TID 0x7f893090a6f0) from PID 0; stack trace: ***
+PC: @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f892fb417d0 (unknown)
+    @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f89304f7f06 google::LogMessage::SendToLog()
+    @     0x7f89304f35af google::LogMessage::Flush()
+    @     0x7f89304f3739 google::LogMessage::~LogMessage()
+    @           0x408cf4 TestLogSinkWaitTillSent()
+    @           0x4115de main
+    @     0x7f892f7ef1c4 (unknown)
+    @           0x4046f9 (unknown)
+
+ +

+By default, the signal handler writes the failure dump to the standard +error. You can customize the destination by InstallFailureWriter(). + +

Miscellaneous Notes

+ +

Performance of Messages

+ +

The conditional logging macros provided by glog (e.g., +CHECK, LOG_IF, VLOG, ...) are +carefully implemented and don't execute the right hand side +expressions when the conditions are false. So, the following check +may not sacrifice the performance of your application. + +

+   CHECK(obj.ok) << obj.CreatePrettyFormattedStringButVerySlow();
+
+ +

User-defined Failure Function

+ +

FATAL severity level messages or unsatisfied +CHECK condition terminate your program. You can change +the behavior of the termination by +InstallFailureFunction. + +

+   void YourFailureFunction() {
+     // Reports something...
+     exit(1);
+   }
+
+   int main(int argc, char* argv[]) {
+     google::InstallFailureFunction(&YourFailureFunction);
+   }
+
+ +

By default, glog tries to dump stacktrace and makes the program +exit with status 1. The stacktrace is produced only when you run the +program on an architecture for which glog supports stack tracing (as +of September 2008, glog supports stack tracing for x86 and x86_64). + +

Raw Logging

+ +

The header file <glog/raw_logging.h> can be +used for thread-safe logging, which does not allocate any memory or +acquire any locks. Therefore, the macros defined in this +header file can be used by low-level memory allocation and +synchronization code. +Please check src/glog/raw_logging.h.in for detail. +

+ +

Google Style perror()

+ +

PLOG() and PLOG_IF() and +PCHECK() behave exactly like their LOG* and +CHECK equivalents with the addition that they append a +description of the current state of errno to their output lines. +E.g. + +

+   PCHECK(write(1, NULL, 2) >= 0) << "Write NULL failed";
+
+ +

This check fails with the following error message. + +

+   F0825 185142 test.cc:22] Check failed: write(1, NULL, 2) >= 0 Write NULL failed: Bad address [14]
+
+ +

Syslog

+ +

SYSLOG, SYSLOG_IF, and +SYSLOG_EVERY_N macros are available. +These log to syslog in addition to the normal logs. Be aware that +logging to syslog can drastically impact performance, especially if +syslog is configured for remote logging! Make sure you understand the +implications of outputting to syslog before you use these macros. In +general, it's wise to use these macros sparingly. + +

Strip Logging Messages

+ +

Strings used in log messages can increase the size of your binary +and present a privacy concern. You can therefore instruct glog to +remove all strings which fall below a certain severity level by using +the GOOGLE_STRIP_LOG macro: + +

If your application has code like this: + +

+   #define GOOGLE_STRIP_LOG 1    // this must go before the #include!
+   #include <glog/logging.h>
+
+ +

The compiler will remove the log messages whose severities are less +than the specified integer value. Since +VLOG logs at the severity level INFO +(numeric value 0), +setting GOOGLE_STRIP_LOG to 1 or greater removes +all log messages associated with VLOGs as well as +INFO log statements. + +

Notes for Windows users

+ +

Google glog defines a severity level ERROR, which is +also defined in windows.h . You can make glog not define +INFO, WARNING, ERROR, +and FATAL by defining +GLOG_NO_ABBREVIATED_SEVERITIES before +including glog/logging.h . Even with this macro, you can +still use the iostream like logging facilities: + +

+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include <windows.h>
+  #include <glog/logging.h>
+
+  // ...
+
+  LOG(ERROR) << "This should work";
+  LOG_IF(ERROR, x > y) << "This should be also OK";
+
+ +

+However, you cannot +use INFO, WARNING, ERROR, +and FATAL anymore for functions defined +in glog/logging.h . + +

+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include <windows.h>
+  #include <glog/logging.h>
+
+  // ...
+
+  // This won't work.
+  // google::FlushLogFiles(google::ERROR);
+
+  // Use this instead.
+  google::FlushLogFiles(google::GLOG_ERROR);
+
+ +

+If you don't need ERROR defined +by windows.h, there are a couple of more workarounds +which sometimes don't work: + +

    +
  • #define WIN32_LEAN_AND_MEAN or NOGDI + before you #include windows.h . +
  • #undef ERROR after you #include + windows.h . +
+ +

Before you use this module, please give the +// name of your internal namespace for this module. Or, if you want +// to expose it, you'll want to move it to the Google namespace. We +// cannot put this class in global namespace because there can be some +// problems when we have multiple versions of Mutex in each shared object. +// +// NOTE: by default, we have #ifdef'ed out the TryLock() method. +// This is for two reasons: +// 1) TryLock() under Windows is a bit annoying (it requires a +// #define to be defined very early). +// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG +// mode. +// If you need TryLock(), and either these two caveats are not a +// problem for you, or you're willing to work around them, then +// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs +// in the code below. +// +// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: +// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html +// Because of that, we might as well use windows locks for +// cygwin. They seem to be more reliable than the cygwin pthreads layer. +// +// TRICKY IMPLEMENTATION NOTE: +// This class is designed to be safe to use during +// dynamic-initialization -- that is, by global constructors that are +// run before main() starts. The issue in this case is that +// dynamic-initialization happens in an unpredictable order, and it +// could be that someone else's dynamic initializer could call a +// function that tries to acquire this mutex -- but that all happens +// before this mutex's constructor has run. (This can happen even if +// the mutex and the function that uses the mutex are in the same .cc +// file.) Basically, because Mutex does non-trivial work in its +// constructor, it's not, in the naive implementation, safe to use +// before dynamic initialization has run on it. +// +// The solution used here is to pair the actual mutex primitive with a +// bool that is set to true when the mutex is dynamically initialized. +// (Before that it's false.) Then we modify all mutex routines to +// look at the bool, and not try to lock/unlock until the bool makes +// it to true (which happens after the Mutex constructor has run.) +// +// This works because before main() starts -- particularly, during +// dynamic initialization -- there are no threads, so a) it's ok that +// the mutex operations are a no-op, since we don't need locking then +// anyway; and b) we can be quite confident our bool won't change +// state between a call to Lock() and a call to Unlock() (that would +// require a global constructor in one translation unit to call Lock() +// and another global constructor in another translation unit to call +// Unlock() later, which is pretty perverse). +// +// That said, it's tricky, and can conceivably fail; it's safest to +// avoid trying to acquire a mutex in a global constructor, if you +// can. One way it can fail is that a really smart compiler might +// initialize the bool to true at static-initialization time (too +// early) rather than at dynamic-initialization time. To discourage +// that, we set is_safe_ to true in code (not the constructor +// colon-initializer) and set it to true via a function that always +// evaluates to true, but that the compiler can't know always +// evaluates to true.

The parent process clone()s a sub-process and runs the death +// test in it; the sub-process exits with code 0 at the end of the +// death test, if it hasn't exited already. +// +// 3. The parent process waits for the sub-process to terminate. +// +// 4. The parent process checks the exit code and error message of +// the sub-process. +// +// Examples: +// +// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number"); +// for (int i = 0; i < 5; i++) { +// EXPECT_DEATH(server.ProcessRequest(i), +// "Invalid request .* in ProcessRequest()") +// << "Failed to die on request " << i; +// } +// +// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting"); +// +// bool KilledBySIGHUP(int exit_code) { +// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP; +// } +// +// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!"); +// +// On the regular expressions used in death tests: +// +// On POSIX-compliant systems (*nix), we use the library, +// which uses the POSIX extended regex syntax. +// +// On other platforms (e.g. Windows), we only support a simple regex +// syntax implemented as part of Google Test. This limited +// implementation should be enough most of the time when writing +// death tests; though it lacks many features you can find in PCRE +// or POSIX extended regex syntax. For example, we don't support +// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and +// repetition count ("x{5,7}"), among others. +// +// Below is the syntax that we do support. We chose it to be a +// subset of both PCRE and POSIX extended regex, so it's easy to +// learn wherever you come from. In the following: 'A' denotes a +// literal character, period (.), or a single \\ escape sequence; +// 'x' and 'y' denote regular expressions; 'm' and 'n' are for +// natural numbers. +// +// c matches any literal character c +// \\d matches any decimal digit +// \\D matches any character that's not a decimal digit +// \\f matches \f +// \\n matches \n +// \\r matches \r +// \\s matches any ASCII whitespace, including \n +// \\S matches any character that's not a whitespace +// \\t matches \t +// \\v matches \v +// \\w matches any letter, _, or decimal digit +// \\W matches any character that \\w doesn't match +// \\c matches any literal character c, which must be a punctuation +// . matches any single character except \n +// A? matches 0 or 1 occurrences of A +// A* matches 0 or many occurrences of A +// A+ matches 1 or many occurrences of A +// ^ matches the beginning of a string (not that of each line) +// $ matches the end of a string (not that of each line) +// xy matches x followed by y +// +// If you accidentally use PCRE or POSIX extended regex features +// not implemented by us, you will get a run-time failure. In that +// case, please try to rewrite your regular expression within the +// above syntax. +// +// This implementation is *not* meant to be as highly tuned or robust +// as a compiled regex library, but should perform well enough for a +// death test, which already incurs significant overhead by launching +// a child process. +// +// Known caveats: +// +// A "threadsafe" style death test obtains the path to the test +// program from argv[0] and re-executes it in the sub-process.

Original patch by Lubomir Marinov. + o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa + o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication. + o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin + o associate an event base with an rpc pool + o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support + o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. + o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. + o Small code cleanups in epoll_dispatch(). + o Increase the maximum number of addresses read from a packet in evdns to 32. + o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. + o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. + o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. + o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. + o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. + o Remove the long-deprecated acconfig.h file. + o Do not require #include before #include . + o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. + o Fix many build issues when using the Microsoft C compiler. + o Remove a bash-ism in autogen.sh + o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne. + o Make the logic for active events work better with internal events; patch from Christopher Layne. + o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne. diff --git a/3rdparty/libevent-1.4.15/Doxyfile b/3rdparty/libevent-1.4.15/Doxyfile new file mode 100644 index 000000000..77f6de89b --- /dev/null +++ b/3rdparty/libevent-1.4.15/Doxyfile @@ -0,0 +1,230 @@ +# Doxyfile 1.5.1 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# The PROJECT_NAME tag is a single word (or a sequence of words surrounded +# by quotes) that should identify the project. + +PROJECT_NAME = libevent + +# Place all output under 'doxygen/' + +OUTPUT_DIRECTORY = doxygen/ + +# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen +# will interpret the first line (until the first dot) of a JavaDoc-style +# comment as the brief description.

If the file handle is created for overlapped input and output (I/O), the application must adjust the position of the file pointer after the read operation. + +This function is designed for both synchronous and asynchronous operation.

You cannot perform asynchronous read operations on mailslots, named pipes, or disk files. + +lpBuffer +[out] Pointer to the buffer that receives the data read from the file. +nNumberOfBytesToRead +[in] Specifies the number of bytes to be read from the file. +lpNumberOfBytesRead +[out] Pointer to the variable that receives the number of bytes read. ReadFile sets this value to zero before doing any work or error checking. If this parameter is zero when ReadFile returns TRUE on a named pipe, the other end of the message-mode pipe called the WriteFile function with nNumberOfBytesToWrite set to zero. +Windows NT/2000/XP: If lpOverlapped is NULL, lpNumberOfBytesRead cannot be NULL. If lpOverlapped is not NULL, lpNumberOfBytesRead can be NULL. If this is an overlapped read operation, you can get the number of bytes read by calling GetOverlappedResult. If hFile is associated with an I/O completion port, you can get the number of bytes read by calling GetQueuedCompletionStatus. + +If I/O completion ports are used and you are using a callback routine to free the memory allocated to the OVERLAPPED structure pointed to by the lpOverlapped parameter, specify NULL as the value of this parameter to avoid a memory corruption problem during the deallocation. This memory corruption problem will cause an invalid number of bytes to be returned in this parameter. + +Windows 95/98/Me: This parameter cannot be NULL. + +lpOverlapped +[in] Pointer to an OVERLAPPED structure. This structure is required if hFile was created with FILE_FLAG_OVERLAPPED. +If hFile was opened with FILE_FLAG_OVERLAPPED, the lpOverlapped parameter must not be NULL. It must point to a valid OVERLAPPED structure. If hFile was created with FILE_FLAG_OVERLAPPED and lpOverlapped is NULL, the function can incorrectly report that the read operation is complete. + +If hFile was opened with FILE_FLAG_OVERLAPPED and lpOverlapped is not NULL, the read operation starts at the offset specified in the OVERLAPPED structure and ReadFile may return before the read operation has been completed. In this case, ReadFile returns FALSE and the GetLastError function returns ERROR_IO_PENDING. This allows the calling process to continue while the read operation finishes. The event specified in the OVERLAPPED structure is set to the signaled state upon completion of the read operation. + +If hFile was not opened with FILE_FLAG_OVERLAPPED and lpOverlapped is NULL, the read operation starts at the current file position and ReadFile does not return until the operation has been completed. + +Windows NT/2000/XP: If hFile is not opened with FILE_FLAG_OVERLAPPED and lpOverlapped is not NULL, the read operation starts at the offset specified in the OVERLAPPED structure. ReadFile does not return until the read operation has been completed. + +Windows 95/98/Me: For operations on files, disks, pipes, or mailslots, this parameter must be NULL; a pointer to an OVERLAPPED structure causes the call to fail. However, Windows 95/98/Me supports overlapped I/O on serial and parallel ports. + +Return Values +The ReadFile function returns when one of the following is true: a write operation completes on the write end of the pipe, the number of bytes requested has been read, or an error occurs. + +If the function succeeds, the return value is nonzero. + +If the return value is nonzero and the number of bytes read is zero, the file pointer was beyond the current end of the file at the time of the read operation. However, if the file was opened with FILE_FLAG_OVERLAPPED and lpOverlapped is not NULL, the return value is FALSE and GetLastError returns ERROR_HANDLE_EOF when the file pointer goes beyond the current end of file. + +If the function fails, the return value is zero. To get extended error information, call GetLastError. + +Remarks +If part of the file is locked by another process and the read operation overlaps the locked portion, this function fails. + +An application must meet certain requirements when working with files opened with FILE_FLAG_NO_BUFFERING: + +File access must begin at byte offsets within the file that are integer multiples of the volume's sector size. To determine a volume's sector size, call the GetDiskFreeSpace function. +File access must be for numbers of bytes that are integer multiples of the volume's sector size. For example, if the sector size is 512 bytes, an application can request reads and writes of 512, 1024, or 2048 bytes, but not of 335, 981, or 7171 bytes. +Buffer addresses for read and write operations must be sector aligned (aligned on addresses in memory that are integer multiples of the volume's sector size). One way to sector align buffers is to use the VirtualAlloc function to allocate the buffers. This function allocates memory that is aligned on addresses that are integer multiples of the system's page size. Because both page and volume sector sizes are powers of 2, memory aligned by multiples of the system's page size is also aligned by multiples of the volume's sector size. +Accessing the input buffer while a read operation is using the buffer may lead to corruption of the data read into that buffer. Applications must not read from, write to, reallocate, or free the input buffer that a read operation is using until the read operation completes. + +Characters can be read from the console input buffer by using ReadFile with a handle to console input. The console mode determines the exact behavior of the ReadFile function. + +If a named pipe is being read in message mode and the next message is longer than the nNumberOfBytesToRead parameter specifies, ReadFile returns FALSE and GetLastError returns ERROR_MORE_DATA. The remainder of the message may be read by a subsequent call to the ReadFile or PeekNamedPipe function. + +When reading from a communications device, the behavior of ReadFile is governed by the current communication time-outs as set and retrieved using the SetCommTimeouts and GetCommTimeouts functions. Unpredictable results can occur if you fail to set the time-out values. For more information about communication time-outs, see COMMTIMEOUTS. + +If ReadFile attempts to read from a mailslot whose buffer is too small, the function returns FALSE and GetLastError returns ERROR_INSUFFICIENT_BUFFER. + +If the anonymous write pipe handle has been closed and ReadFile attempts to read using the corresponding anonymous read pipe handle, the function returns FALSE and GetLastError returns ERROR_BROKEN_PIPE. + +The ReadFile function may fail and return ERROR_INVALID_USER_BUFFER or ERROR_NOT_ENOUGH_MEMORY whenever there are too many outstanding asynchronous I/O requests. + +The ReadFile code to check for the end-of-file condition (eof) differs for synchronous and asynchronous read operations. + +When a synchronous read operation reaches the end of a file, ReadFile returns TRUE and sets *lpNumberOfBytesRead to zero. The following sample code tests for end-of-file for a synchronous read operation: + +// Attempt a synchronous read operation. +bResult = ReadFile(hFile, &inBuffer, nBytesToRead, &nBytesRead, NULL) ; +// Check for end of file. +if (bResult && nBytesRead == 0, ) +{ + // we're at the end of the file +} +An asynchronous read operation can encounter the end of a file during the initiating call to ReadFile, or during subsequent asynchronous operation. + +If EOF is detected at ReadFile time for an asynchronous read operation, ReadFile returns FALSE and GetLastError returns ERROR_HANDLE_EOF. + +If EOF is detected during subsequent asynchronous operation, the call to GetOverlappedResult to obtain the results of that operation returns FALSE and GetLastError returns ERROR_HANDLE_EOF. + +To cancel all pending asynchronous I/O operations, use the CancelIo function. This function only cancels operations issued by the calling thread for the specified file handle. I/O operations that are canceled complete with the error ERROR_OPERATION_ABORTED. + +If you are attempting to read from a floppy drive that does not have a floppy disk, the system displays a message box prompting the user to retry the operation. To prevent the system from displaying this message box, call the SetErrorMode function with SEM_NOOPENFILEERRORBOX. + +The following sample code illustrates testing for end-of-file for an asynchronous read operation: + +// set up overlapped structure fields +gOverLapped.Offset = 0; +gOverLapped.OffsetHigh = 0; +gOverLapped.hEvent = hEvent; + +// attempt an asynchronous read operation +bResult = ReadFile(hFile, &inBuffer, nBytesToRead, &nBytesRead, + &gOverlapped) ; + +// if there was a problem, or the async. operation's still pending ... +if (!bResult) +{ + // deal with the error code + switch (dwError = GetLastError()) + { + case ERROR_HANDLE_EOF: + { + // we have reached the end of the file + // during the call to ReadFile + + // code to handle that + } + + case ERROR_IO_PENDING: + { + // asynchronous i/o is still in progress + + // do something else for a while + GoDoSomethingElse() ; + + // check on the results of the asynchronous read + bResult = GetOverlappedResult(hFile, &gOverlapped, + &nBytesRead, FALSE) ; + + // if there was a problem ... + if (!bResult) + { + // deal with the error code + switch (dwError = GetLastError()) + { + case ERROR_HANDLE_EOF: + { + // we have reached the end of + // the file during asynchronous + // operation + } + + // deal with other error cases + } + } + } // end case + + // deal with other error cases + + } // end switch +} // end if +Example Code +For an example, see Reading, Writing, and Locking Files. + +Requirements + Windows NT/2000/XP: Included in Windows NT 3.1 and later. + Windows 95/98/Me: Included in Windows 95 and later. + Header: Declared in Winbase.h; include Windows.h. + Library: Use Kernel32.lib. + +See Also +File I/O Overview, File I/O Functions, CancelIo, CreateFile, GetCommTimeouts, GetOverlappedResult, GetQueuedCompletionStatus, OVERLAPPED, PeekNamedPipe, ReadFileEx, SetCommTimeouts, SetErrorMode, WriteFile + +Platform SDK Release: November 2001 What did you think of this topic? +Let us know.

Before you use this library you should see if libc +can do the job for you with the modern async call getaddrinfo_a +(see http://www.imperialviolet.org/page25.html#e498). Otherwise, +please continue. +.Pp +This code is based on libevent and you must call event_init before +any of the APIs in this file. You must also seed the OpenSSL random +source if you are using OpenSSL for ids (see below). +.Pp +This library is designed to be included and shipped with your source +code. You statically link with it. You should also test for the +existence of strtok_r and define HAVE_STRTOK_R if you have it. +.Pp +The DNS protocol requires a good source of id numbers and these +numbers should be unpredictable for spoofing reasons. There are +three methods for generating them here and you must define exactly +one of them. In increasing order of preference: +.Pp +.Bl -tag -width "DNS_USE_GETTIMEOFDAY_FOR_ID" -compact -offset indent +.It DNS_USE_GETTIMEOFDAY_FOR_ID +Using the bottom 16 bits of the usec result from gettimeofday. This +is a pretty poor solution but should work anywhere. +.It DNS_USE_CPU_CLOCK_FOR_ID +Using the bottom 16 bits of the nsec result from the CPU's time +counter. This is better, but may not work everywhere. Requires +POSIX realtime support and you'll need to link against -lrt on +glibc systems at least. +.It DNS_USE_OPENSSL_FOR_ID +Uses the OpenSSL RAND_bytes call to generate the data. You must +have seeded the pool before making any calls to this library. +.El +.Pp +The library keeps track of the state of nameservers and will avoid +them when they go down. Otherwise it will round robin between them. +.Pp +Quick start guide: + #include "evdns.h" + void callback(int result, char type, int count, int ttl, + void *addresses, void *arg); + evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + evdns_resolve("www.hostname.com", 0, callback, NULL); +.Pp +When the lookup is complete the callback function is called. The +first argument will be one of the DNS_ERR_* defines in evdns.h. +Hopefully it will be DNS_ERR_NONE, in which case type will be +DNS_IPv4_A, count will be the number of IP addresses, ttl is the time +which the data can be cached for (in seconds), addresses will point +to an array of uint32_t's and arg will be whatever you passed to +evdns_resolve. +.Pp +Searching: +.Pp +In order for this library to be a good replacement for glibc's resolver it +supports searching. This involves setting a list of default domains, in +which names will be queried for. The number of dots in the query name +determines the order in which this list is used. +.Pp +Searching appears to be a single lookup from the point of view of the API, +although many DNS queries may be generated from a single call to +evdns_resolve. Searching can also drastically slow down the resolution +of names. +.Pp +To disable searching: +.Bl -enum -compact -offset indent +.It +Never set it up. If you never call +.Fn evdns_resolv_conf_parse, +.Fn evdns_init, +or +.Fn evdns_search_add +then no searching will occur. +.It +If you do call +.Fn evdns_resolv_conf_parse +then don't pass +.Va DNS_OPTION_SEARCH +(or +.Va DNS_OPTIONS_ALL, +which implies it). +.It +When calling +.Fn evdns_resolve, +pass the +.Va DNS_QUERY_NO_SEARCH +flag. +.El +.Pp +The order of searches depends on the number of dots in the name. If the +number is greater than the ndots setting then the names is first tried +globally. Otherwise each search domain is appended in turn. +.Pp +The ndots setting can either be set from a resolv.conf, or by calling +evdns_search_ndots_set. +.Pp +For example, with ndots set to 1 (the default) and a search domain list of +["myhome.net"]: + Query: www + Order: www.myhome.net, www. +.Pp + Query: www.abc + Order: www.abc., www.abc.myhome.net +.Pp +.Sh API reference +.Pp +.Bl -tag -width 0123456 +.It Ft int Fn evdns_init +Initializes support for non-blocking name resolution by calling +.Fn evdns_resolv_conf_parse +on UNIX and +.Fn evdns_config_windows_nameservers +on Windows. +.It Ft int Fn evdns_nameserver_add "unsigned long int address" +Add a nameserver. The address should be an IP address in +network byte order. The type of address is chosen so that +it matches in_addr.s_addr. +Returns non-zero on error. +.It Ft int Fn evdns_nameserver_ip_add "const char *ip_as_string" +This wraps the above function by parsing a string as an IP +address and adds it as a nameserver. +Returns non-zero on error +.It Ft int Fn evdns_resolve "const char *name" "int flags" "evdns_callback_type callback" "void *ptr" +Resolve a name. The name parameter should be a DNS name. +The flags parameter should be 0, or DNS_QUERY_NO_SEARCH +which disables searching for this query. (see defn of +searching above). +.Pp +The callback argument is a function which is called when +this query completes and ptr is an argument which is passed +to that callback function. +.Pp +Returns non-zero on error +.It Ft void Fn evdns_search_clear +Clears the list of search domains +.It Ft void Fn evdns_search_add "const char *domain" +Add a domain to the list of search domains +.It Ft void Fn evdns_search_ndots_set "int ndots" +Set the number of dots which, when found in a name, causes +the first query to be without any search domain. +.It Ft int Fn evdns_count_nameservers "void" +Return the number of configured nameservers (not necessarily the +number of running nameservers). This is useful for double-checking +whether our calls to the various nameserver configuration functions +have been successful. +.It Ft int Fn evdns_clear_nameservers_and_suspend "void" +Remove all currently configured nameservers, and suspend all pending +resolves. Resolves will not necessarily be re-attempted until +evdns_resume() is called. +.It Ft int Fn evdns_resume "void" +Re-attempt resolves left in limbo after an earlier call to +evdns_clear_nameservers_and_suspend(). +.It Ft int Fn evdns_config_windows_nameservers "void" +Attempt to configure a set of nameservers based on platform settings on +a win32 host.

The first is the inflight queue. In +this queue requests have an allocated transaction id and nameserver. +They will soon be transmitted if they haven't already been. +.Pp +The second is the waiting queue. The size of the inflight ring is +limited and all other requests wait in waiting queue for space. This +bounds the number of concurrent requests so that we don't flood the +nameserver. Several algorithms require a full walk of the inflight +queue and so bounding its size keeps thing going nicely under huge +(many thousands of requests) loads. +.Pp +If a nameserver loses too many requests it is considered down and we +try not to use it. After a while we send a probe to that nameserver +(a lookup for google.com) and, if it replies, we consider it working +again. If the nameserver fails a probe we wait longer to try again +with the next probe. +.Sh SEE ALSO +.Xr event 3 , +.Xr gethostbyname 3 , +.Xr resolv.conf 5 +.Sh HISTORY +The +.Nm evdns +API was developed by Adam Langley on top of the +.Nm libevent +API. +The code was integrate into +.Nm Tor +by Nick Mathewson and finally put into +.Nm libevent +itself by Niels Provos. +.Sh AUTHORS +The +.Nm evdns +API and code was written by Adam Langley with significant +contributions by Nick Mathewson. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rdparty/libevent-1.4.15/evdns.c b/3rdparty/libevent-1.4.15/evdns.c new file mode 100644 index 000000000..dec9b30bf --- /dev/null +++ b/3rdparty/libevent-1.4.15/evdns.c @@ -0,0 +1,3190 @@ +/* $Id: evdns.c 6979 2006-08-04 18:31:13Z nickm $ */ + +/* The original version of this module was written by Adam Langley; for + * a history of modifications, check out the subversion logs. + * + * When editing this module, try to keep it re-mergeable by Adam.

Before you use this library you should see if libc + * can do the job for you with the modern async call getaddrinfo_a + * (see http://www.imperialviolet.org/page25.html#e498). Otherwise, + * please continue. + * + * This code is based on libevent and you must call event_init before + * any of the APIs in this file. You must also seed the OpenSSL random + * source if you are using OpenSSL for ids (see below). + * + * This library is designed to be included and shipped with your source + * code. You statically link with it. You should also test for the + * existence of strtok_r and define HAVE_STRTOK_R if you have it. + * + * The DNS protocol requires a good source of id numbers and these + * numbers should be unpredictable for spoofing reasons. There are + * three methods for generating them here and you must define exactly + * one of them. In increasing order of preference: + * + * DNS_USE_GETTIMEOFDAY_FOR_ID: + * Using the bottom 16 bits of the usec result from gettimeofday. This + * is a pretty poor solution but should work anywhere. + * DNS_USE_CPU_CLOCK_FOR_ID: + * Using the bottom 16 bits of the nsec result from the CPU's time + * counter. This is better, but may not work everywhere. Requires + * POSIX realtime support and you'll need to link against -lrt on + * glibc systems at least. + * DNS_USE_OPENSSL_FOR_ID: + * Uses the OpenSSL RAND_bytes call to generate the data. You must + * have seeded the pool before making any calls to this library. + * + * The library keeps track of the state of nameservers and will avoid + * them when they go down. Otherwise it will round robin between them. + * + * Quick start guide: + * #include "evdns.h" + * void callback(int result, char type, int count, int ttl, + * void *addresses, void *arg); + * evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + * evdns_resolve("www.hostname.com", 0, callback, NULL); + * + * When the lookup is complete the callback function is called. The + * first argument will be one of the DNS_ERR_* defines in evdns.h. + * Hopefully it will be DNS_ERR_NONE, in which case type will be + * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time + * which the data can be cached for (in seconds), addresses will point + * to an array of uint32_t's and arg will be whatever you passed to + * evdns_resolve. + * + * Searching: + * + * In order for this library to be a good replacement for glibc's resolver it + * supports searching. This involves setting a list of default domains, in + * which names will be queried for. The number of dots in the query name + * determines the order in which this list is used. + * + * Searching appears to be a single lookup from the point of view of the API, + * although many DNS queries may be generated from a single call to + * evdns_resolve. Searching can also drastically slow down the resolution + * of names. + * + * To disable searching: + * 1. Never set it up. If you never call evdns_resolv_conf_parse or + * evdns_search_add then no searching will occur. + * + * 2. If you do call evdns_resolv_conf_parse then don't pass + * DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it). + * + * 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag. + * + * The order of searches depends on the number of dots in the name. If the + * number is greater than the ndots setting then the names is first tried + * globally. Otherwise each search domain is appended in turn. + * + * The ndots setting can either be set from a resolv.conf, or by calling + * evdns_search_ndots_set. + * + * For example, with ndots set to 1 (the default) and a search domain list of + * ["myhome.net"]: + * Query: www + * Order: www.myhome.net, www. + * + * Query: www.abc + * Order: www.abc., www.abc.myhome.net + * + * Internals: + * + * Requests are kept in two queues. The first is the inflight queue. In + * this queue requests have an allocated transaction id and nameserver. + * They will soon be transmitted if they haven't already been. + * + * The second is the waiting queue. The size of the inflight ring is + * limited and all other requests wait in waiting queue for space. This + * bounds the number of concurrent requests so that we don't flood the + * nameserver. Several algorithms require a full walk of the inflight + * queue and so bounding its size keeps thing going nicely under huge + * (many thousands of requests) loads. + * + * If a nameserver loses too many requests it is considered down and we + * try not to use it. After a while we send a probe to that nameserver + * (a lookup for google.com) and, if it replies, we consider it working + * again.

mechanism to execute a function when a specific event +on a file descriptor occurs or after a given time has passed. +.Pp +The +.Nm event +API needs to be initialized with +.Fn event_init +before it can be used. +.Pp +In order to process events, an application needs to call +.Fn event_dispatch . +This function only returns on error, and should replace the event core +of the application program. +.Pp +The function +.Fn event_set +prepares the event structure +.Fa ev +to be used in future calls to +.Fn event_add +and +.Fn event_del . +The event will be prepared to call the function specified by the +.Fa fn +argument with an +.Fa int +argument indicating the file descriptor, a +.Fa short +argument indicating the type of event, and a +.Fa void * +argument given in the +.Fa arg +argument. +The +.Fa fd +indicates the file descriptor that should be monitored for events. +The events can be either +.Va EV_READ , +.Va EV_WRITE , +or both, +indicating that an application can read or write from the file descriptor +respectively without blocking. +.Pp +The function +.Fa fn +will be called with the file descriptor that triggered the event and +the type of event which will be either +.Va EV_TIMEOUT , +.Va EV_SIGNAL , +.Va EV_READ , +or +.Va EV_WRITE . +Additionally, an event which has registered interest in more than one of the +preceeding events, via bitwise-OR to +.Fn event_set , +can provide its callback function with a bitwise-OR of more than one triggered +event. +The additional flag +.Va EV_PERSIST +makes an +.Fn event_add +persistent until +.Fn event_del +has been called. +.Pp +Once initialized, the +.Fa ev +structure can be used repeatedly with +.Fn event_add +and +.Fn event_del +and does not need to be reinitialized unless the function called and/or +the argument to it are to be changed. +However, when an +.Fa ev +structure has been added to libevent using +.Fn event_add +the structure must persist until the event occurs (assuming +.Fa EV_PERSIST +is not set) or is removed +using +.Fn event_del . +You may not reuse the same +.Fa ev +structure for multiple monitored descriptors; each descriptor +needs its own +.Fa ev . +.Pp +The function +.Fn event_add +schedules the execution of the +.Fa ev +event when the event specified in +.Fn event_set +occurs or in at least the time specified in the +.Fa tv . +If +.Fa tv +is +.Dv NULL , +no timeout occurs and the function will only be called +if a matching event occurs on the file descriptor. +The event in the +.Fa ev +argument must be already initialized by +.Fn event_set +and may not be used in calls to +.Fn event_set +until it has timed out or been removed with +.Fn event_del . +If the event in the +.Fa ev +argument already has a scheduled timeout, the old timeout will be +replaced by the new one. +.Pp +The function +.Fn event_del +will cancel the event in the argument +.Fa ev . +If the event has already executed or has never been added +the call will have no effect. +.Pp +The functions +.Fn evtimer_set , +.Fn evtimer_add , +.Fn evtimer_del , +.Fn evtimer_initialized , +and +.Fn evtimer_pending +are abbreviations for common situations where only a timeout is required. +The file descriptor passed will be \-1, and the event type will be +.Va EV_TIMEOUT . +.Pp +The functions +.Fn signal_set , +.Fn signal_add , +.Fn signal_del , +.Fn signal_initialized , +and +.Fn signal_pending +are abbreviations. +The event type will be a persistent +.Va EV_SIGNAL . +That means +.Fn signal_set +adds +.Va EV_PERSIST . +.Pp +In order to avoid races in signal handlers, the +.Nm event +API provides two variables: +.Va event_sigcb +and +.Va event_gotsig . +A signal handler +sets +.Va event_gotsig +to indicate that a signal has been received. +The application sets +.Va event_sigcb +to a callback function. +After the signal handler sets +.Va event_gotsig , +.Nm event_dispatch +will execute the callback function to process received signals. +The callback returns 1 when no events are registered any more. +It can return \-1 to indicate an error to the +.Nm event +library, causing +.Fn event_dispatch +to terminate with +.Va errno +set to +.Er EINTR . +.Pp +The function +.Fn event_once +is similar to +.Fn event_set . +However, it schedules a callback to be called exactly once and does not +require the caller to prepare an +.Fa event +structure. +This function supports +.Fa EV_TIMEOUT , +.Fa EV_READ , +and +.Fa EV_WRITE . +.Pp +The +.Fn event_pending +function can be used to check if the event specified by +.Fa event +is pending to run. +If +.Va EV_TIMEOUT +was specified and +.Fa tv +is not +.Dv NULL , +the expiration time of the event will be returned in +.Fa tv . +.Pp +The +.Fn event_initialized +macro can be used to check if an event has been initialized. +.Pp +The +.Nm event_loop +function provides an interface for single pass execution of pending +events. +The flags +.Va EVLOOP_ONCE +and +.Va EVLOOP_NONBLOCK +are recognized. +The +.Nm event_loopexit +function exits from the event loop. The next +.Fn event_loop +iteration after the +given timer expires will complete normally (handling all queued events) then +exit without blocking for events again. Subsequent invocations of +.Fn event_loop +will proceed normally. +The +.Nm event_loopbreak +function exits from the event loop immediately. +.Fn event_loop +will abort after the next event is completed; +.Fn event_loopbreak +is typically invoked from this event's callback. This behavior is analogous +to the "break;" statement. Subsequent invocations of +.Fn event_loop +will proceed normally. +.Pp +It is the responsibility of the caller to provide these functions with +pre-allocated event structures. +.Pp +.Sh EVENT PRIORITIES +By default +.Nm libevent +schedules all active events with the same priority. +However, sometimes it is desirable to process some events with a higher +priority than others. +For that reason, +.Nm libevent +supports strict priority queues. +Active events with a lower priority are always processed before events +with a higher priority. +.Pp +The number of different priorities can be set initially with the +.Fn event_priority_init +function. +This function should be called before the first call to +.Fn event_dispatch . +The +.Fn event_priority_set +function can be used to assign a priority to an event. +By default, +.Nm libevent +assigns the middle priority to all events unless their priority +is explicitly set. +.Sh THREAD SAFE EVENTS +.Nm Libevent +has experimental support for thread-safe events. +When initializing the library via +.Fn event_init , +an event base is returned. +This event base can be used in conjunction with calls to +.Fn event_base_set , +.Fn event_base_dispatch , +.Fn event_base_loop , +.Fn event_base_loopexit , +.Fn bufferevent_base_set +and +.Fn event_base_free . +.Fn event_base_set +should be called after preparing an event with +.Fn event_set , +as +.Fn event_set +assigns the provided event to the most recently created event base. +.Fn bufferevent_base_set +should be called after preparing a bufferevent with +.Fn bufferevent_new . +.Fn event_base_free +should be used to free memory associated with the event base +when it is no longer needed. +.Sh BUFFERED EVENTS +.Nm libevent +provides an abstraction on top of the regular event callbacks. +This abstraction is called a +.Va "buffered event" . +A buffered event provides input and output buffers that get filled +and drained automatically. +The user of a buffered event no longer deals directly with the IO, +but instead is reading from input and writing to output buffers. +.Pp +A new bufferevent is created by +.Fn bufferevent_new . +The parameter +.Fa fd +specifies the file descriptor from which data is read and written to. +This file descriptor is not allowed to be a +.Xr pipe 2 . +The next three parameters are callbacks. +The read and write callback have the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" . +The error callback has the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" . +The argument is specified by the fourth parameter +.Fa "cbarg" . +A +.Fa bufferevent struct +pointer is returned on success, NULL on error. +Both the read and the write callback may be NULL. +The error callback has to be always provided. +.Pp +Once initialized, the bufferevent structure can be used repeatedly with +bufferevent_enable() and bufferevent_disable(). +The flags parameter can be a combination of +.Va EV_READ +and +.Va EV_WRITE . +When read enabled the bufferevent will try to read from the file +descriptor and call the read callback. +The write callback is executed +whenever the output buffer is drained below the write low watermark, +which is +.Va 0 +by default. +.Pp +The +.Fn bufferevent_write +function can be used to write data to the file descriptor. +The data is appended to the output buffer and written to the descriptor +automatically as it becomes available for writing. +.Fn bufferevent_write +returns 0 on success or \-1 on failure. +The +.Fn bufferevent_read +function is used to read data from the input buffer, +returning the amount of data read. +.Pp +If multiple bases are in use, bufferevent_base_set() must be called before +enabling the bufferevent for the first time. +.Sh NON-BLOCKING HTTP SUPPORT +.Nm libevent +provides a very thin HTTP layer that can be used both to host an HTTP +server and also to make HTTP requests. +An HTTP server can be created by calling +.Fn evhttp_new . +It can be bound to any port and address with the +.Fn evhttp_bind_socket +function. +When the HTTP server is no longer used, it can be freed via +.Fn evhttp_free . +.Pp +To be notified of HTTP requests, a user needs to register callbacks with the +HTTP server. +This can be done by calling +.Fn evhttp_set_cb . +The second argument is the URI for which a callback is being registered. +The corresponding callback will receive an +.Va struct evhttp_request +object that contains all information about the request. +.Pp +This section does not document all the possible function calls; please +check +.Va event.h +for the public interfaces. +.Sh ADDITIONAL NOTES +It is possible to disable support for +.Va epoll , kqueue , devpoll , poll +or +.Va select +by setting the environment variable +.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL +or +.Va EVENT_NOSELECT , +respectively. +By setting the environment variable +.Va EVENT_SHOW_METHOD , +.Nm libevent +displays the kernel notification method that it uses. +.Sh RETURN VALUES +Upon successful completion +.Fn event_add +and +.Fn event_del +return 0. +Otherwise, \-1 is returned and the global variable errno is +set to indicate the error. +.Sh SEE ALSO +.Xr kqueue 2 , +.Xr poll 2 , +.Xr select 2 , +.Xr evdns 3 , +.Xr timeout 9 +.Sh HISTORY +The +.Nm event +API manpage is based on the +.Xr timeout 9 +manpage by Artur Grabowski. +The port of +.Nm libevent +to Windows is due to Michael A. Davis. +Support for real-time signals is due to Taral. +.Sh AUTHORS +The +.Nm event +library was written by Niels Provos. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rdparty/libevent-1.4.15/event.c b/3rdparty/libevent-1.4.15/event.c new file mode 100644 index 000000000..da6cd4252 --- /dev/null +++ b/3rdparty/libevent-1.4.15/event.c @@ -0,0 +1,1036 @@ +/* + * Copyright (c) 2000-2004 Niels Provos + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

The libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, libevent also support callbacks due + to signals or regular timeouts. + + libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_dispatch() and then add or + remove events dynamically without having to change the event loop. + + Currently, libevent supports /dev/poll, kqueue(2), select(2), poll(2) and + epoll(4). It also has experimental support for real-time signals. The + internal event mechanism is completely independent of the exposed event API, + and a simple update of libevent can provide new functionality without having + to redesign the applications. As a result, Libevent allows for portable + application development and provides the most scalable event notification + mechanism available on an operating system. Libevent can also be used for + multi-threaded aplications; see Steven Grimm's explanation. Libevent should + compile on Linux, *BSD, Mac OS X, Solaris and Windows. + + @section usage Standard usage + + Every program that uses libevent must include the header, and pass + the -levent flag to the linker. Before using any of the functions in the + library, you must call event_init() or event_base_new() to perform one-time + initialization of the libevent library. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must declare an event + structure and call event_set() to initialize the members of the structure. + To enable notification, you add the structure to the list of monitored + events by calling event_add(). The event structure must remain allocated as + long as it is active, so it should be allocated on the heap. Finally, you + call event_dispatch() to loop and dispatch events. + + @section bufferevent I/O Buffers + + libevent provides an abstraction on top of the regular event callbacks. This + abstraction is called a buffered event. A buffered event provides input and + output buffers that get filled and drained automatically. The user of a + buffered event no longer deals directly with the I/O, but instead is reading + from input and writing to output buffers. + + Once initialized via bufferevent_new(), the bufferevent structure can be + used repeatedly with bufferevent_enable() and bufferevent_disable(). + Instead of reading and writing directly to a socket, you would call + bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + @section timers Timers + + libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_set() function prepares an + event struct to be used as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + + @section timeouts Timeouts + + In addition to simple timers, libevent can assign timeout events to file + descriptors that are triggered whenever a certain amount of time has passed + with no activity on a file descriptor. The timeout_set() function + initializes an event struct for use as a timeout. Once initialized, the + event must be activated by using timeout_add(). To cancel the timeout, call + timeout_del(). + + @section evdns Asynchronous DNS resolution + + libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. These functions can be imported by + including the header in your program. Before using any of the + resolver functions, you must call evdns_init() to initialize the library. To + convert a hostname to an IP address, you call the evdns_resolve_ipv4() + function. To perform a reverse lookup, you would call the + evdns_resolve_reverse() function. All of these functions use callbacks to + avoid blocking while the lookup is performed. + + @section evhttp Event-driven HTTP servers + + libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the header in your + program. You create the server by calling evhttp_new(). Add addresses and + ports to listen on with evhttp_bind_socket(). You then register one or more + callbacks to handle incoming requests. Each URI can be assigned a callback + via the evhttp_set_cb() function. A generic callback function can also be + registered via evhttp_set_gencb(); this callback will be invoked if no other + callbacks have been registered for a given URI. + + @section evrpc A framework for RPC servers and clients + + libevents provides a framework for creating RPC servers and clients. It + takes care of marshaling and unmarshaling all data structures. + + @section api API Reference + + To browse the complete documentation of the libevent API, click on any of + the following links. + + event.h + The primary libevent header + + evdns.h + Asynchronous DNS resolution + + evhttp.h + An embedded libevent-based HTTP server + + evrpc.h + A framework for creating RPC servers and clients + + */ + +/** @file event.h + + A library for writing event-driven network servers + + */ + +#ifdef __cplusplus +extern "C" { +#endif + +#include +#ifdef _EVENT_HAVE_SYS_TYPES_H +#include +#endif +#ifdef _EVENT_HAVE_SYS_TIME_H +#include +#endif +#ifdef _EVENT_HAVE_STDINT_H +#include +#endif +#include + +/* For int types. */ +#include + +#ifdef WIN32 +#define WIN32_LEAN_AND_MEAN +#include +#undef WIN32_LEAN_AND_MEAN +typedef unsigned char u_char; +typedef unsigned short u_short; +#endif + +#define EVLIST_TIMEOUT 0x01 +#define EVLIST_INSERTED 0x02 +#define EVLIST_SIGNAL 0x04 +#define EVLIST_ACTIVE 0x08 +#define EVLIST_INTERNAL 0x10 +#define EVLIST_INIT 0x80 + +/* EVLIST_X_ Private space: 0x1000-0xf000 */ +#define EVLIST_ALL (0xf000 | 0x9f) + +#define EV_TIMEOUT 0x01 +#define EV_READ 0x02 +#define EV_WRITE 0x04 +#define EV_SIGNAL 0x08 +#define EV_PERSIST 0x10 /* Persistant event */ + +/* Fix so that ppl dont have to run with */ +#ifndef TAILQ_ENTRY +#define _EVENT_DEFINED_TQENTRY +#define TAILQ_ENTRY(type) \ +struct { \ + struct type *tqe_next; /* next element */ \ + struct type **tqe_prev; /* address of previous next element */ \ +} +#endif /* !TAILQ_ENTRY */ + +struct event_base; +#ifndef EVENT_NO_STRUCT +struct event { + TAILQ_ENTRY (event) ev_next; + TAILQ_ENTRY (event) ev_active_next; + TAILQ_ENTRY (event) ev_signal_next; + unsigned int min_heap_idx; /* for managing timeouts */ + + struct event_base *ev_base; + + int ev_fd; + short ev_events; + short ev_ncalls; + short *ev_pncalls; /* Allows deletes in callback */ + + struct timeval ev_timeout; + + int ev_pri; /* smaller numbers are higher priority */ + + void (*ev_callback)(int, short, void *arg); + void *ev_arg; + + int ev_res; /* result passed to event callback */ + int ev_flags; +}; +#else +struct event; +#endif + +#define EVENT_SIGNAL(ev) (int)(ev)->ev_fd +#define EVENT_FD(ev) (int)(ev)->ev_fd + +/* + * Key-Value pairs.

About this document + + This document describes the key differences between Libevent 1.3 and + Libevent 1.4, from a user's point of view. It was most recently + updated based on features from libevent 1.4.2-rc. + +1. Packaging Issues. + +1.1. The great library division. + + The libevent source now builds two libraries: libevent_core and + libevent_extra. The libevent_core library includes event loops, + timers, buffer code, and various small compatibility functions. The + libevent_extra library includes code for HTTP, DNS, RPC, and so on. + Thus, if you're writing software that only uses libevent's event + loop, you should link against only the libevent_core library, + whereas if you're writing software that uses libevent's protocol + support as well, you need to link libevent_extra as well. + + For backward compatibility, libevent also builds a library called + "libevent" that includes everything. + +1.2. The event-config.h header + + Libevent configure script now builds two headers from its configure + script: config.h (which it uses internally) and event-config.h + (which it installs as a header file). All of the macros in + event-config.h are modified so that they're safe to include in other + projects. This allows libevent's header files (like event.h and + evutil.h) information about platform configuration. + + What does this mean for you? As of 1.4.x, it should never be + necessary to include extra files or define extra types before you + include event.h (or any other libevent header); event.h can now look + at the information in event-config.h and figure out what it needs to + include. + +1.3. Documentation + + Libevent now includes better doxygen documentation. It's not + perfect or complete, though; if you find a mistake, please let us + know. + +1.4. Libtool usage + + We now use libtool's library versioning support correctly. If we + don't mess this up, it means that binaries linked against old + version of libevent should continue working when we make changes to + libevent that don't break backward compatibility. + +1.5. Portability + + Libevent now builds with MSVC again. We've only tested it with MSVC + 2005, and the project files might not be right. Please let us know + if you run into any issues. + + Libevent now builds on platforms where /bin/sh is not bash. + + Libevent's regression test no longer requires Python to be + installed. + +2. New and Improved APIs: + + (This list includes functions that are new, functions whose behavior + has changed, and functions that were included in previous releases + but which never actually worked before.) + +2.1. Utility functions are defined in evutil.h + + Libevent now exposes a small set of functions for cross-platform + network programming in evutil.h, on the theory that they've been + useful enough to us that other people may likely want to use them + too. These are mainly workarounds for Windows issues for now: they + include evutil_socketpair (to fake socketpair on platforms that + don't have it) and evutil_make_socket_nonblocking (to make a socket + nonblocking in a cross-platform way. See the header for more + information. + +2.2. In the libevent core. + + The event_base_free() function now works. Previously, it would + crash with an assertion failure if there were events pending on a + base. Now, it simply deletes all the pending events and frees the + base. Be careful -- this might leak fds and memory associated with + the old events. To avoid leaks, you should still remove all the + events and free their resources before you delete the base. + + Libevent should now work properly with fork(). Just call + event_reinit() on your event base after the fork call, and it should + work okay. Please let us know about any bugs you find. + + There's a new event_base_new() function that acts just like + event_init(), but does not replace the default base. If you are + using multiple event bases in your code, you should just use + event_base_new() instead of event_init(), to avoid accidental bugs. + + There's new event_loopbreak() function to make a current event loop + stop exiting and return. Unlike event_loopexit, it stops subsequent + pending events from getting executed. This behavior is useful for + scripting languages to implement exceptions from inside callbacks. + + There's a new event_base_get_method() function, for use in place of + event_get_method() in multi-base applications. + +2.3. New in HTTP. + + There's an evhttp_connection_set_local_address() function you can + use to set the local address of an HTTP connection. + + HTTP/1.1 chunking now correctly ends chunks with '\r\n'. + +2.4. New in DNS + + Instead of picking your method for generating DNS transaction IDs at + startup, you can use evdns_set_transaction_id() to provide a + transaction ID function at runtime. + + The "class" field in evdns_server_request is now renamed to + dns_question_class, so that it won't break compilation under C++. + This uses some preprocessor hacks so that C code using the old name + won't break. Eventually, the old name will be deprecated entirely; + please don't use it. + +2.5. New in RPC + + There are now hooks on RPC input and output; can be used to + implement RPC independent processing such as compression or + authentication. + + RPC tags can now be up to 32 bits. This is wire-compatible, but + changes some of the types in the APIs. Please let us know if this + is problematic for you. + +3. Big bugfixes + + We've done a lot, with help from users on different platforms, to + make the different backends behave more similarly with respect to + signals and timeouts. The kqueue and solaris backends were the big + offenders previously, but they should be better now. Windows should + be better too, though it's likely that problems remain there. + + The libevent headers (though not the source files!) should now build + cleanly on C++. + + (For more bugfixes, see the ChangeLog file. These are only the + biggies.) + +4. Big performance improvements + + Libevent now uses a min-heap rather than a red-black tree to track + timeouts. This means that finding the next timeout to fire is now + O(1) instead of (lg n). + + The win32 select-based backend now uses a red-black tree to map + SOCKET handles to event structures. This changes the performance + characteristics of the event loop on win32 from O(n^2) to O(n lg n). + Not perfect, but better. + +5. Removed code and features + + The rtsig backend is now removed. It hasn't even compiled for a + while, and nobody seemed to miss it very much. All the platforms + that have rtsig seem to have a better option instead these days. + Please let us know if rtsig was crucial for you. + diff --git a/3rdparty/libevent-release-2.1.8-stable/.clang-format b/3rdparty/libevent-release-2.1.8-stable/.clang-format new file mode 100644 index 000000000..a9722db28 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/.clang-format @@ -0,0 +1,63 @@ +--- +Language: Cpp +BasedOnStyle: LLVM + +AccessModifierOffset: -4 + +AlignAfterOpenBracket: DontAlign +AlignEscapedNewlinesLeft: true +# AlignOperands: true +AlignTrailingComments: true + +AllowAllParametersOfDeclarationOnNextLine: true +AllowShortBlocksOnASingleLine: false +AllowShortCaseLabelsOnASingleLine: false +AllowShortFunctionsOnASingleLine: All +AllowShortIfStatementsOnASingleLine: false +AllowShortLoopsOnASingleLine: false + +AlwaysBreakAfterDefinitionReturnType: All +AlwaysBreakBeforeMultilineStrings: false +AlwaysBreakTemplateDeclarations: false + +# BinPackArguments: false +# BinPackParameters: true + +BreakBeforeBinaryOperators: false +BreakBeforeBraces: Custom +BraceWrapping: { AfterFunction: true } +BreakBeforeTernaryOperators: true +BreakConstructorInitializersBeforeComma: true + +ColumnLimit: 80 + +ContinuationIndentWidth: 4 + +DerivePointerAlignment: false #XXX +DisableFormat: false +ExperimentalAutoDetectBinPacking: false #XXX +ForEachMacros: [ LIST_FOREACH, SIMPLEQ_FOREACH, CIRCLEQ_FOREACH, TAILQ_FOREACH, TAILQ_FOREACH_REVERSE, HT_FOREACH ] + +IndentCaseLabels: false +IndentFunctionDeclarationAfterType: false +IndentWidth: 4 +IndentWrappedFunctionNames: false + +KeepEmptyLinesAtTheStartOfBlocks: true +MaxEmptyLinesToKeep: 2 + +PointerAlignment: Right #XXX + +# SpaceAfterCStyleCast: false +SpaceBeforeAssignmentOperators: true +SpaceBeforeParens: ControlStatements +SpaceInEmptyParentheses: false +SpacesBeforeTrailingComments: 1 +SpacesInAngles: false +SpacesInCStyleCastParentheses: false +SpacesInParentheses: false +Standard: Cpp03 +TabWidth: 4 +UseTab: Always +SortIncludes: false +... diff --git a/3rdparty/libevent-release-2.1.8-stable/.gitignore b/3rdparty/libevent-release-2.1.8-stable/.gitignore new file mode 100644 index 000000000..996100453 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/.gitignore @@ -0,0 +1,149 @@ +### These files should get ignored no matter where they appear. + +# Editors leave these lying around +\#*\# +.#* +*~ +*.swp + +# C stuff +*.o + +# Windows stuff +*.obj +*.exe +*.lib + +# Patch leaves these lying arround +*.orig +*.rej + +# gcov stuff +*.gcno +*.gcov +*.gcda + +# gdb stuff +.gdb_history + +# Autotools stuff +.deps +.dirstamp +Makefile +Makefile.in + +# Libtool stuff +.libs +*.lo +*.la + +# ctags stuff +TAGS +tags + +# cscope stuff +cscope* + +# Stuff made by our makefiles +*.pc +*.log +*.trs + +## The initial / makes these files only get ignored in particular directories. +/autom4te.cache + +# configure in progress +/.cyg* +/confdefs.* +/conftest.* + +# Libtool adds these, at least sometimes +/m4/libtool.m4 +/m4/ltoptions.m4 +/m4/ltsugar.m4 +/m4/ltversion.m4 +/m4/lt~obsolete.m4 + +/aclocal.m4 +/compile +/doxygen +/config.cache +/config.guess +/config.log +/config.status +/config.sub +/configure +/configure.lineno +/depcomp +/config.h +/config.h.in +/install-sh +/libtool +/ltmain.sh +/missing +/stamp-h1 +/stamp-h2 + +/include/event2/event-config.h +/evconfig-private.h + +/sample/dns-example +/sample/event-read-fifo +/sample/hello-world +/sample/http-server +/sample/http-connect +/sample/le-proxy +/sample/https-client +/sample/signal-test +/sample/time-test +/sample/event-test + +/test-driver +/test/bench +/test/bench_cascade +/test/bench_http +/test/bench_httpclient +/test/regress +/test/regress.gen.c +/test/regress.gen.h +/test/rpcgen-attempted +/test/test-dumpevents +/test/test-eof +/test/test-closed +/test/test-init +/test/test-ratelim +/test/test-script.sh +/test/test-time +/test/test-weof +/test/test-changelist +/test/test-fdleak + + +# Files generated by cmake +/CMakeCache.txt +/CMakeFiles/ +/CTestTestfile.cmake +/DartConfiguration.tcl +/LibeventConfig.cmake +/LibeventConfigVersion.cmake +/LibeventTargets.cmake +/bin/ +/cmake_install.cmake +/include/evconfig-private.h +/lib/ +/tmp/ +/verify_tests.sh +/verify_tests.bat +/event.dir +/event_core.dir +/event_extra.dir +*.vcxproj +*.sln +*.filters + +# make dist +/COPYING +/INSTALL +/*.tar.gz + +/.vagrant diff --git a/3rdparty/libevent-release-2.1.8-stable/.travis.yml b/3rdparty/libevent-release-2.1.8-stable/.travis.yml new file mode 100644 index 000000000..cc370e9f0 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/.travis.yml @@ -0,0 +1,100 @@ +os: + -

Libevent + applications should now be more resilient to jumps forwards or backwards + in the system clock. Also, on Linux systems with epoll, we now + optionally support microsecond-level timeouts (whereas epoll only + supports millisecond-precision timeouts). + + o Use mach_absolute_time() for monotonic clock support on OSX.

Original patch by Lubomir Marinov. + o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa + o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication. + o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin + o associate an event base with an rpc pool + o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support + o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. + o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. + o Small code cleanups in epoll_dispatch(). + o Increase the maximum number of addresses read from a packet in evdns to 32. + o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. + o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. + o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. + o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. + o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. + o Remove the long-deprecated acconfig.h file. + o Do not require #include before #include . + o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. + o Fix many build issues when using the Microsoft C compiler. + o Remove a bash-ism in autogen.sh + o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne. + o Make the logic for active events work better with internal events; patch from Christopher Layne. + o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne. diff --git a/3rdparty/libevent-release-2.1.8-stable/ChangeLog-2.0 b/3rdparty/libevent-release-2.1.8-stable/ChangeLog-2.0 new file mode 100644 index 000000000..a925d33b1 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/ChangeLog-2.0 @@ -0,0 +1,1280 @@ +Changes in version 2.0.21-stable (18 Nov 2012) +BUGFIXES: + o ssl: Don't discard SSL read event when timeout and read come close together (576b29f) + o ssl: Stop looping in "consider_reading" if reading is suspended.

(Found by Rocco Carbone.) + o Export new evutil_ascii_* functions to perform locale-independent character type operations. + o Try to compile better with MSVC: patches from Brodie Thiesfield + o New evconnlistener_get_fd function to expose a listener's associated socket. + o Expose an ev_socklen_t type for consistent use across platforms. + o Make bufferevent_socket_connect() work when the original fd was -1. + o Fix a bug in bufferevent_socket_connect() when the connection succeeds too quickly. + o Export an evutil_sockaddr_cmp() to compare to sockaddr objects for equality. + o Add a bufferevent_get_enabled() to tell what a bufferevent has been configured to do. + o Add an evbuffer_search_eol() function to locate the end of a line nondestructively. + o Add an evbuffer_search_range() function to search a bounded range of a buffer. + o Fix a rare crash bug in evdns. + o Have bufferevent_socket_connect() with no arguments put a bufferevent into connecting mode. + o Support sendfile on Solaris: patch from Caitlin Mercer. + o New functions to explicitly reference a socket used by an evhttp object. Patches from David Reiss. + o When we send a BEV_EVENT_CONNECTED to indicate connected status, we no longer invoke the write callback as well unless we actually wrote data too. + o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov. + o Do not detect whether we have monotonic clock support every time a new event base is created: instead do it only once. Patch taken from Chromium. + o Do not allocate the maximum event queue for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 374K per epoll-based event_base. Resolves bug 2839240. + o Treat an event with a negative fd as valid but untriggerable by Libevent. This is useful for applications that want to manually activate events. + o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h + o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec + o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak(). Patch from Ka-Hing Cheung. + o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. + o Fix some bugs when using the old evdns interfaces to initialize the evdns module. + o Detect errors during bufferevent_connect(). Patch from Christopher Davis. + o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. + o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. + o Fix a bug when using a specialized memory allocator on win32. + o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. + o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. + o Add an API to replace all fatal calls to exit() with a user-provided panic function. + o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. + o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. + o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. + o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. + o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. + o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. + o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. + o New event_base_config option to disable the timeval cache entirely. + o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. + o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. + o Fix a problem with excessive memory allocation when using multiple event priorities. + o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. + o Never check the environment when we're running setuid or setgid; from OpenBSD. + o Options passed to evdns_set_option() no longer need to end with a colon. + o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. + o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. + o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. + o Numerous other bugfixes. + o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. + o Fix a race condition in the pthreads test case; found by Nick Mathewson + o Remove most calls to event_err() in http and deal with memory errors instead + + + +Changes in 2.0.2-alpha (25 Jul 2009): + o Add a new flag to bufferevents to make all callbacks automatically deferred. + o Make evdns functionality locked, and automatically defer dns callbacks. + o Fix a possible free(NULL) when freeing an event_base with no signals. + o Add a flag to disable checking environment varibles when making an event_base + o Disallow setting less than 1 priority. + o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] + o Use signal.h, not sys/signal.h. [Patch from mmadia] + o Try harder to build with certain older c99 compilers. + o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] + o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] + o Make sendfile work on FreeBSD + o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. + o Actually define the event_config_set_flag() function. + o Try harder to compile with Visual C++. + o Move event_set() and its allies to event2/event_compat.h where they belong. + o Remove the event_gotsig code, which has long been deprecated and unused. + o Add an event_get_base() function to return the base assigned to an event. + o New function to automate connecting on a socket-based bufferevent. + o New functions to automate listening for incoming TCP connections. + o Do case-insensitive checks with a locale-independent comparison function. + o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. + o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. + o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h + o Add a bufferevent_getfd() function to mirror bufferevent_setfd() + o Make bufferevent_setfd() return an error code if the operation is not successful. + o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. + o Cap the maximum number of priorities at 256. + o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. + o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information + o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. + o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. + o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) + o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) + o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. + o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). + o Replace some read()/write() instances with send()/recv() to work properly on win32. + o Set truncated flag correctly in evdns server replies. + o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg + o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. + o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. + o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg + o Mitigate a race condition when using socket bufferevents in multiple threads. + o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. + o Do not allow event_del(ev) to return while that event's callback is executing in another thread. This fixes a nasty race condition. + o event_get_supported_methods() now lists methods that have been disabled with the EVENT_NO* environment options. + o Rename encode_int[64] to evtag_encode_int[64] to avoid polluting the global namespace.

Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb + o Check return value of event_add in signal.c + o provide event_reinit() to reintialize an event_base after fork + o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. + o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. + o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. + o Check return value of event_add in signal.c + o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. + o Do not mangle socket handles on 64-bit windows. + o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.) + o move EV_PERSIST handling out of the event backends + o small improvements to evhttp documentation + o always generate Date and Content-Length headers for HTTP/1.1 replies + o set the correct event base for HTTP close events + o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. + o Rewrite win32.c backend to be O(n lg n) rather than O(n^2). + o Removed obsoleted recalc code + o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. + o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures. + o prefix {encode,decode}_tag functions with evtag to avoid collisions + o fix a bug with event_rpcgen for integers + o Correctly handle DNS replies with no answers set (Fixes bug 1846282) + o add -Wstrict-aliasing to warnings and more cleanup + o removed linger from http server socket; reported by Ilya Martynov + o event_rpcgen now allows creating integer arrays + o support string arrays in event_rpcgen + o change evrpc hooking to allow pausing of RPCs; this will make it possible for the hook to do some meaning ful work; this is not backwards compatible. + o allow an http request callback to take ownership of a request structure + o allow association of meta data with RPC requests for hook processing + o associate more context for hooks to query such as the connection object + o remove pending timeouts on event_base_free() + o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards + o devpoll and evport need reinit; tested by W.C.A Wijngaards + o event_base_get_method; from Springande Ulv + o Send CRLF after each chunk in HTTP output, for compliance with RFC2626.

This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed. + o Make name_from_addr() threadsafe in http.c + o Add new thread-safe interfaces to evdns functions. + o Make all event_tagging interfaces threadsafe. + o Rename internal memory management functions. + o New functions (event_assign, event_new, event_free) for use by apps that want to be safely threadsafe, or want to remain ignorant of the contents of struct event. + o introduce bufferevent_read_buffer; allows reading without memory copy. + o expose bufferevent_setwatermark via header files and fix high watermark on read + o fix a bug in buffrevent read water marks and add a test for them + o fix a bug in which bufferevent_write_buffer would not schedule a write event + o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure + o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents + o convert evhttp_connection to use bufferevents. + o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy. + o Remove the never-exported, never-used evhttp_hostportfile function. + o Support input/output filters for bufferevents; somewhat similar to libio's model. This will allow us to implement SSL, compression, etc, transparently to users of bufferevents such as the http layer. + o allow connections to be removed from an rpc pool + o add new evtimer_assign, signal_assign, evtimer_new, and signal_new functions to manipulate timer and signal events, analagous to the now-recommended event_assign and event_new + o switch internal uses of event_set over to use event_assign. + o introduce evbuffer_contiguous_space() api that tells a user how much data is available in the first buffer chain + o introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient. + o reduce system calls for getting current time by caching it. + o separate signal events from io events; making the code less complex. + o support for periodic timeouts + o support for virtual HTTP hosts. + o turn event_initialized() into a function, and add function equivalents to EVENT_SIGNAL and EVENT_FD so that people don't need to include event_struct.h + o Build test directory correctly with CPPFLAGS set. + o Provide an API for retrieving the supported event mechanisms. + o event_base_new_with_config() and corresponding config APIs. + o migrate the evhttp header to event2/ but accessors are still missing. + o deprecate timeout_* event functions by moving them to event_compat.h + o Move windows gettimeofday replacement into a new evutil_gettimeofday(). + o Make configure script work on IRIX. + o provide a method for canceling ongoing http requests. + o Make vsnprintf() returns consistent on win32. + o Fix connection keep-alive behavior for HTTP/1.0 + o Fix use of freed memory in event_reinit; pointed out by Peter Postma + o constify struct timeval * where possible + o make event_get_supported_methods obey environment variables + o support for edge-triggered events on epoll and kqueue backends: patch from Valery Kholodkov + o support for selecting event backends by their features, and for querying the features of a backend. + o change failing behavior of event_base_new_with_config: if a config is provided and no backend is selected, return NULL instead of aborting. + o deliver partial data to request callbacks when chunked callback is set even if there is no chunking on the http level; allows cancelation of requests from within the chunked callback; from Scott Lamb. + o allow min_heap_erase to be called on removed members; from liusifan. + o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT.

This helps resist DNS poisoning attacks. + o Make the http connection close detection work properly with bufferevents and fix a potential memory leak associated with it. + o Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. + o Add generic implementations for parsing and emiting IPv6 addresses on platforms that do not have inet_ntop and/or inet_pton. + o Allow DNS servers that have IPv6 addresses. + o Add an evbuffer_write_atmost() function to write a limited number of bytes to an fd. + o Refactor internal notify-main-thread logic to prefer eventfd to pipe, then pipe to socketpair, and only use socketpairs as a last resort. + o Try harder to pack all evbuffer reads into as few chains as possible, using readv/WSARecv as appropriate. + o New evthread_use_windows_threads() and evthread_use_pthreads() functions to set up the evthread callbacks with reasonable defaults. + o Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. + o sendfile, mmap and memory reference support for evbuffers. + o New evutil_make_listen_socket_reuseable() to abstract SO_REUSEADDR. + o New bind-to option to allow DNS clients to bind to an arbitrary port for outgoing requests. + o evbuffers can now be "frozen" to prevent operations at one or both ends. + o Bufferevents now notice external attempts to add data to an inbuf or remove it from an outbuf, and stop them. + o Fix parsing of queries where the encoded queries contained \r, \n or + + o Do not allow internal events to starve lower-priority events. + diff --git a/3rdparty/libevent-release-2.1.8-stable/Doxyfile b/3rdparty/libevent-release-2.1.8-stable/Doxyfile new file mode 100644 index 000000000..d9d660345 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/Doxyfile @@ -0,0 +1,257 @@ +# Doxyfile 1.5.1 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# The PROJECT_NAME tag is a single word (or a sequence of words surrounded +# by quotes) that should identify the project. + +PROJECT_NAME = libevent + +# Place all output under 'doxygen/' + +OUTPUT_DIRECTORY = doxygen/ + +# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen +# will interpret the first line (until the first dot) of a JavaDoc-style +# comment as the brief description.

BUILDING AND INSTALLATION (In Depth) + +## Autoconf + +To build libevent, type + + $ ./configure && make + + + (If you got libevent from the git repository, you will + first need to run the included "autogen.sh" script in order to + generate the configure script.) + +You can run the regression tests by running + + $ make verify + +Install as root via + + $ make install + +Before reporting any problems, please run the regression tests. + +To enable the low-level tracing build the library as: + + $ CFLAGS=-DUSE_DEBUG ./configure [...] + +Standard configure flags should work. In particular, see: + + --disable-shared Only build static libraries + --prefix Install all files relative to this directory. + + +The configure script also supports the following flags: + + --enable-gcc-warnings Enable extra compiler checking with GCC. + --disable-malloc-replacement + Don't let applications replace our memory + management functions + --disable-openssl Disable support for OpenSSL encryption. + --disable-thread-support Don't support multithreaded environments. + +## CMake (Windows) + +(Note that autoconf is currently the most mature and supported build +enviroment for libevent; the cmake instructions here are new and +experimental, though they _should_ be solid. We hope that cmake will +still be supported in future versions of Libevent, and will try to +make sure that happens.) + +First of all install . + +To build libevent using Microsoft Visual studio open the "Visual Studio Command prompt" and type: + +``` +$ cd +$ mkdir build && cd build +$ cmake -G "Visual Studio 10" .. # Or whatever generator you want to use cmake --help for a list. +$ start libevent.sln +``` + +In the above, the ".." refers to the dir containing the Libevent source code. +You can build multiple versions (with different compile time settings) from the same source tree +by creating other build directories. + +It is highly recommended to build "out of source" when using +CMake instead of "in source" like the normal behaviour of autoconf for this reason. + +The "NMake Makefiles" CMake generator can be used to build entirely via the command line. + +To get a list of settings available for the project you can type: + +``` +$ cmake -LH .. +``` + +### GUI + +CMake also provides a GUI that lets you specify the source directory and output (binary) directory +that the build should be placed in. + +### OpenSSL support + +To build Libevent with OpenSSL support you will need to have OpenSSL binaries available when building, +these can be found here: + +# 2. USEFUL LINKS: + +For the latest released version of Libevent, see the official website at + . + +There's a pretty good work-in-progress manual up at + . + +For the latest development versions of Libevent, access our Git repository +via + +``` +$ git clone https://github.com/libevent/libevent.git +``` + +You can browse the git repository online at: + + + +To report bugs, issues, or ask for new features: + +__Patches__: https://github.com/libevent/libevent/pulls +> OK, those are not really _patches_ You fork, modify, and hit the "Create Pull Request" button. +> You can still submit normal git patchs via the mailing list. + +__Bugs, Features [RFC], and Issus__: https://github.com/libevent/libevent/issues +> Or you can do it via the mailing list. + +There's also a libevent-users mailing list for talking about Libevent +use and development: + + + +# 3.

The + * amortized cost for a sequence of m accesses to a splay tree is O(lg n); + * + * A red-black tree is a binary search tree with the node color as an + * extra attribute. It fulfills a set of conditions: + * - every search path from the root to a leaf consists of the + * same number of black nodes, + * - each red node (except for the root) has a black parent, + * - each leaf node is black. + * + * Every operation on a red-black tree is bounded as O(lg n). + * The maximum height of a red-black tree is 2lg (n+1). + */ + +#define SPLAY_HEAD(name, type) \ +struct name { \ + struct type *sph_root;

Before you use this library you should see if libc +can do the job for you with the modern async call getaddrinfo_a +(see http://www.imperialviolet.org/page25.html#e498). Otherwise, +please continue. +.Pp +This code is based on libevent and you must call event_init before +any of the APIs in this file. You must also seed the OpenSSL random +source if you are using OpenSSL for ids (see below). +.Pp +This library is designed to be included and shipped with your source +code. You statically link with it. You should also test for the +existence of strtok_r and define HAVE_STRTOK_R if you have it. +.Pp +The DNS protocol requires a good source of id numbers and these +numbers should be unpredictable for spoofing reasons. There are +three methods for generating them here and you must define exactly +one of them. In increasing order of preference: +.Pp +.Bl -tag -width "DNS_USE_GETTIMEOFDAY_FOR_ID" -compact -offset indent +.It DNS_USE_GETTIMEOFDAY_FOR_ID +Using the bottom 16 bits of the usec result from gettimeofday. This +is a pretty poor solution but should work anywhere. +.It DNS_USE_CPU_CLOCK_FOR_ID +Using the bottom 16 bits of the nsec result from the CPU's time +counter. This is better, but may not work everywhere. Requires +POSIX realtime support and you'll need to link against -lrt on +glibc systems at least. +.It DNS_USE_OPENSSL_FOR_ID +Uses the OpenSSL RAND_bytes call to generate the data. You must +have seeded the pool before making any calls to this library. +.El +.Pp +The library keeps track of the state of nameservers and will avoid +them when they go down. Otherwise it will round robin between them. +.Pp +Quick start guide: + #include "evdns.h" + void callback(int result, char type, int count, int ttl, + void *addresses, void *arg); + evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + evdns_resolve("www.hostname.com", 0, callback, NULL); +.Pp +When the lookup is complete the callback function is called. The +first argument will be one of the DNS_ERR_* defines in evdns.h. +Hopefully it will be DNS_ERR_NONE, in which case type will be +DNS_IPv4_A, count will be the number of IP addresses, ttl is the time +which the data can be cached for (in seconds), addresses will point +to an array of uint32_t's and arg will be whatever you passed to +evdns_resolve. +.Pp +Searching: +.Pp +In order for this library to be a good replacement for glibc's resolver it +supports searching. This involves setting a list of default domains, in +which names will be queried for. The number of dots in the query name +determines the order in which this list is used. +.Pp +Searching appears to be a single lookup from the point of view of the API, +although many DNS queries may be generated from a single call to +evdns_resolve. Searching can also drastically slow down the resolution +of names. +.Pp +To disable searching: +.Bl -enum -compact -offset indent +.It +Never set it up. If you never call +.Fn evdns_resolv_conf_parse, +.Fn evdns_init, +or +.Fn evdns_search_add +then no searching will occur. +.It +If you do call +.Fn evdns_resolv_conf_parse +then don't pass +.Va DNS_OPTION_SEARCH +(or +.Va DNS_OPTIONS_ALL, +which implies it). +.It +When calling +.Fn evdns_resolve, +pass the +.Va DNS_QUERY_NO_SEARCH +flag. +.El +.Pp +The order of searches depends on the number of dots in the name. If the +number is greater than the ndots setting then the names is first tried +globally. Otherwise each search domain is appended in turn. +.Pp +The ndots setting can either be set from a resolv.conf, or by calling +evdns_search_ndots_set. +.Pp +For example, with ndots set to 1 (the default) and a search domain list of +["myhome.net"]: + Query: www + Order: www.myhome.net, www. +.Pp + Query: www.abc + Order: www.abc., www.abc.myhome.net +.Pp +.Sh API reference +.Pp +.Bl -tag -width 0123456 +.It Ft int Fn evdns_init +Initializes support for non-blocking name resolution by calling +.Fn evdns_resolv_conf_parse +on UNIX and +.Fn evdns_config_windows_nameservers +on Windows. +.It Ft int Fn evdns_nameserver_add "unsigned long int address" +Add a nameserver.

The name parameter should be a DNS name. +The flags parameter should be 0, or DNS_QUERY_NO_SEARCH +which disables searching for this query. (see defn of +searching above). +.Pp +The callback argument is a function which is called when +this query completes and ptr is an argument which is passed +to that callback function. +.Pp +Returns non-zero on error +.It Ft void Fn evdns_search_clear +Clears the list of search domains +.It Ft void Fn evdns_search_add "const char *domain" +Add a domain to the list of search domains +.It Ft void Fn evdns_search_ndots_set "int ndots" +Set the number of dots which, when found in a name, causes +the first query to be without any search domain. +.It Ft int Fn evdns_count_nameservers "void" +Return the number of configured nameservers (not necessarily the +number of running nameservers).

The first is the inflight queue. In +this queue requests have an allocated transaction id and nameserver. +They will soon be transmitted if they haven't already been. +.Pp +The second is the waiting queue. The size of the inflight ring is +limited and all other requests wait in waiting queue for space. This +bounds the number of concurrent requests so that we don't flood the +nameserver. Several algorithms require a full walk of the inflight +queue and so bounding its size keeps thing going nicely under huge +(many thousands of requests) loads. +.Pp +If a nameserver loses too many requests it is considered down and we +try not to use it. After a while we send a probe to that nameserver +(a lookup for google.com) and, if it replies, we consider it working +again. If the nameserver fails a probe we wait longer to try again +with the next probe. +.Sh SEE ALSO +.Xr event 3 , +.Xr gethostbyname 3 , +.Xr resolv.conf 5 +.Sh HISTORY +The +.Nm evdns +API was developed by Adam Langley on top of the +.Nm libevent +API. +The code was integrate into +.Nm Tor +by Nick Mathewson and finally put into +.Nm libevent +itself by Niels Provos. +.Sh AUTHORS +The +.Nm evdns +API and code was written by Adam Langley with significant +contributions by Nick Mathewson. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rdparty/libevent-release-2.1.8-stable/evdns.c b/3rdparty/libevent-release-2.1.8-stable/evdns.c new file mode 100644 index 000000000..e9dbc35c6 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/evdns.c @@ -0,0 +1,4767 @@ +/* Copyright 2006-2007 Niels Provos + * Copyright 2007-2012 Nick Mathewson and Niels Provos + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

event +API provides a mechanism to execute a function when a specific event +on a file descriptor occurs or after a given time has passed. +.Pp +The +.Nm event +API needs to be initialized with +.Fn event_init +before it can be used. +.Pp +In order to process events, an application needs to call +.Fn event_dispatch . +This function only returns on error, and should replace the event core +of the application program. +.Pp +The function +.Fn event_set +prepares the event structure +.Fa ev +to be used in future calls to +.Fn event_add +and +.Fn event_del . +The event will be prepared to call the function specified by the +.Fa fn +argument with an +.Fa int +argument indicating the file descriptor, a +.Fa short +argument indicating the type of event, and a +.Fa void * +argument given in the +.Fa arg +argument. +The +.Fa fd +indicates the file descriptor that should be monitored for events. +The events can be either +.Va EV_READ , +.Va EV_WRITE , +or both, +indicating that an application can read or write from the file descriptor +respectively without blocking. +.Pp +The function +.Fa fn +will be called with the file descriptor that triggered the event and +the type of event which will be either +.Va EV_TIMEOUT , +.Va EV_SIGNAL , +.Va EV_READ , +or +.Va EV_WRITE . +Additionally, an event which has registered interest in more than one of the +preceeding events, via bitwise-OR to +.Fn event_set , +can provide its callback function with a bitwise-OR of more than one triggered +event. +The additional flag +.Va EV_PERSIST +makes an +.Fn event_add +persistent until +.Fn event_del +has been called. +.Pp +Once initialized, the +.Fa ev +structure can be used repeatedly with +.Fn event_add +and +.Fn event_del +and does not need to be reinitialized unless the function called and/or +the argument to it are to be changed. +However, when an +.Fa ev +structure has been added to libevent using +.Fn event_add +the structure must persist until the event occurs (assuming +.Fa EV_PERSIST +is not set) or is removed +using +.Fn event_del . +You may not reuse the same +.Fa ev +structure for multiple monitored descriptors; each descriptor +needs its own +.Fa ev . +.Pp +The function +.Fn event_add +schedules the execution of the +.Fa ev +event when the event specified in +.Fn event_set +occurs or in at least the time specified in the +.Fa tv . +If +.Fa tv +is +.Dv NULL , +no timeout occurs and the function will only be called +if a matching event occurs on the file descriptor. +The event in the +.Fa ev +argument must be already initialized by +.Fn event_set +and may not be used in calls to +.Fn event_set +until it has timed out or been removed with +.Fn event_del . +If the event in the +.Fa ev +argument already has a scheduled timeout, the old timeout will be +replaced by the new one. +.Pp +The function +.Fn event_del +will cancel the event in the argument +.Fa ev . +If the event has already executed or has never been added +the call will have no effect. +.Pp +The functions +.Fn evtimer_set , +.Fn evtimer_add , +.Fn evtimer_del , +.Fn evtimer_initialized , +and +.Fn evtimer_pending +are abbreviations for common situations where only a timeout is required. +The file descriptor passed will be \-1, and the event type will be +.Va EV_TIMEOUT . +.Pp +The functions +.Fn signal_set , +.Fn signal_add , +.Fn signal_del , +.Fn signal_initialized , +and +.Fn signal_pending +are abbreviations. +The event type will be a persistent +.Va EV_SIGNAL . +That means +.Fn signal_set +adds +.Va EV_PERSIST . +.Pp +In order to avoid races in signal handlers, the +.Nm event +API provides two variables: +.Va event_sigcb +and +.Va event_gotsig . +A signal handler +sets +.Va event_gotsig +to indicate that a signal has been received. +The application sets +.Va event_sigcb +to a callback function. +After the signal handler sets +.Va event_gotsig , +.Nm event_dispatch +will execute the callback function to process received signals. +The callback returns 1 when no events are registered any more. +It can return \-1 to indicate an error to the +.Nm event +library, causing +.Fn event_dispatch +to terminate with +.Va errno +set to +.Er EINTR . +.Pp +The function +.Fn event_once +is similar to +.Fn event_set . +However, it schedules a callback to be called exactly once and does not +require the caller to prepare an +.Fa event +structure. +This function supports +.Fa EV_TIMEOUT , +.Fa EV_READ , +and +.Fa EV_WRITE . +.Pp +The +.Fn event_pending +function can be used to check if the event specified by +.Fa event +is pending to run. +If +.Va EV_TIMEOUT +was specified and +.Fa tv +is not +.Dv NULL , +the expiration time of the event will be returned in +.Fa tv . +.Pp +The +.Fn event_initialized +macro can be used to check if an event has been initialized. +.Pp +The +.Nm event_loop +function provides an interface for single pass execution of pending +events. +The flags +.Va EVLOOP_ONCE +and +.Va EVLOOP_NONBLOCK +are recognized. +The +.Nm event_loopexit +function exits from the event loop. The next +.Fn event_loop +iteration after the +given timer expires will complete normally (handling all queued events) then +exit without blocking for events again. Subsequent invocations of +.Fn event_loop +will proceed normally. +The +.Nm event_loopbreak +function exits from the event loop immediately. +.Fn event_loop +will abort after the next event is completed; +.Fn event_loopbreak +is typically invoked from this event's callback. This behavior is analogous +to the "break;" statement. Subsequent invocations of +.Fn event_loop +will proceed normally. +.Pp +It is the responsibility of the caller to provide these functions with +pre-allocated event structures. +.Pp +.Sh EVENT PRIORITIES +By default +.Nm libevent +schedules all active events with the same priority. +However, sometimes it is desirable to process some events with a higher +priority than others. +For that reason, +.Nm libevent +supports strict priority queues. +Active events with a lower priority are always processed before events +with a higher priority. +.Pp +The number of different priorities can be set initially with the +.Fn event_priority_init +function. +This function should be called before the first call to +.Fn event_dispatch . +The +.Fn event_priority_set +function can be used to assign a priority to an event. +By default, +.Nm libevent +assigns the middle priority to all events unless their priority +is explicitly set. +.Sh THREAD SAFE EVENTS +.Nm Libevent +has experimental support for thread-safe events. +When initializing the library via +.Fn event_init , +an event base is returned. +This event base can be used in conjunction with calls to +.Fn event_base_set , +.Fn event_base_dispatch , +.Fn event_base_loop , +.Fn event_base_loopexit , +.Fn bufferevent_base_set +and +.Fn event_base_free . +.Fn event_base_set +should be called after preparing an event with +.Fn event_set , +as +.Fn event_set +assigns the provided event to the most recently created event base. +.Fn bufferevent_base_set +should be called after preparing a bufferevent with +.Fn bufferevent_new . +.Fn event_base_free +should be used to free memory associated with the event base +when it is no longer needed. +.Sh BUFFERED EVENTS +.Nm libevent +provides an abstraction on top of the regular event callbacks. +This abstraction is called a +.Va "buffered event" . +A buffered event provides input and output buffers that get filled +and drained automatically. +The user of a buffered event no longer deals directly with the IO, +but instead is reading from input and writing to output buffers. +.Pp +A new bufferevent is created by +.Fn bufferevent_new . +The parameter +.Fa fd +specifies the file descriptor from which data is read and written to. +This file descriptor is not allowed to be a +.Xr pipe 2 . +The next three parameters are callbacks. +The read and write callback have the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" . +The error callback has the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" . +The argument is specified by the fourth parameter +.Fa "cbarg" . +A +.Fa bufferevent struct +pointer is returned on success, NULL on error. +Both the read and the write callback may be NULL. +The error callback has to be always provided. +.Pp +Once initialized, the bufferevent structure can be used repeatedly with +bufferevent_enable() and bufferevent_disable(). +The flags parameter can be a combination of +.Va EV_READ +and +.Va EV_WRITE . +When read enabled the bufferevent will try to read from the file +descriptor and call the read callback. +The write callback is executed +whenever the output buffer is drained below the write low watermark, +which is +.Va 0 +by default. +.Pp +The +.Fn bufferevent_write +function can be used to write data to the file descriptor. +The data is appended to the output buffer and written to the descriptor +automatically as it becomes available for writing. +.Fn bufferevent_write +returns 0 on success or \-1 on failure. +The +.Fn bufferevent_read +function is used to read data from the input buffer, +returning the amount of data read. +.Pp +If multiple bases are in use, bufferevent_base_set() must be called before +enabling the bufferevent for the first time. +.Sh NON-BLOCKING HTTP SUPPORT +.Nm libevent +provides a very thin HTTP layer that can be used both to host an HTTP +server and also to make HTTP requests. +An HTTP server can be created by calling +.Fn evhttp_new . +It can be bound to any port and address with the +.Fn evhttp_bind_socket +function. +When the HTTP server is no longer used, it can be freed via +.Fn evhttp_free . +.Pp +To be notified of HTTP requests, a user needs to register callbacks with the +HTTP server. +This can be done by calling +.Fn evhttp_set_cb . +The second argument is the URI for which a callback is being registered. +The corresponding callback will receive an +.Va struct evhttp_request +object that contains all information about the request. +.Pp +This section does not document all the possible function calls; please +check +.Va event.h +for the public interfaces. +.Sh ADDITIONAL NOTES +It is possible to disable support for +.Va epoll , kqueue , devpoll , poll +or +.Va select +by setting the environment variable +.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL +or +.Va EVENT_NOSELECT , +respectively. +By setting the environment variable +.Va EVENT_SHOW_METHOD , +.Nm libevent +displays the kernel notification method that it uses. +.Sh RETURN VALUES +Upon successful completion +.Fn event_add +and +.Fn event_del +return 0. +Otherwise, \-1 is returned and the global variable errno is +set to indicate the error. +.Sh SEE ALSO +.Xr kqueue 2 , +.Xr poll 2 , +.Xr select 2 , +.Xr evdns 3 , +.Xr timeout 9 +.Sh HISTORY +The +.Nm event +API manpage is based on the +.Xr timeout 9 +manpage by Artur Grabowski. +The port of +.Nm libevent +to Windows is due to Michael A. Davis. +Support for real-time signals is due to Taral. +.Sh AUTHORS +The +.Nm event +library was written by Niels Provos. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rdparty/libevent-release-2.1.8-stable/event.c b/3rdparty/libevent-release-2.1.8-stable/event.c new file mode 100644 index 000000000..503003e24 --- /dev/null +++ b/3rdparty/libevent-release-2.1.8-stable/event.c @@ -0,0 +1,3940 @@ +/* + * Copyright (c) 2000-2007 Niels Provos + * Copyright (c) 2007-2012 Niels Provos and Nick Mathewson + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

As a + result, evbuffers can be used to pass data around without actually + incurring the overhead of copying the data. + + A new evbuffer can be allocated with evbuffer_new(), and can be + freed with evbuffer_free(). Most users will be using evbuffers via + the bufferevent interface. To access a bufferevent's evbuffers, use + bufferevent_get_input() and bufferevent_get_output(). + + There are several guidelines for using evbuffers. + + - if you already know how much data you are going to add as a result + of calling evbuffer_add() multiple times, it makes sense to use + evbuffer_expand() first to make sure that enough memory is allocated + before hand. + + - evbuffer_add_buffer() adds the contents of one buffer to the other + without incurring any unnecessary memory copies. + + - evbuffer_add() and evbuffer_add_buffer() do not mix very well: + if you use them, you will wind up with fragmented memory in your + buffer. + + - For high-performance code, you may want to avoid copying data into and out + of buffers. You can skip the copy step by using + evbuffer_reserve_space()/evbuffer_commit_space() when writing into a + buffer, and evbuffer_peek() when reading. + + In Libevent 2.0 and later, evbuffers are represented using a linked + list of memory chunks, with pointers to the first and last chunk in + the chain. + + As the contents of an evbuffer can be stored in multiple different + memory blocks, it cannot be accessed directly. Instead, evbuffer_pullup() + can be used to force a specified number of bytes to be contiguous. This + will cause memory reallocation and memory copies if the data is split + across multiple blocks.

Before you use this library you should see if libc + * can do the job for you with the modern async call getaddrinfo_a + * (see http://www.imperialviolet.org/page25.html#e498). Otherwise, + * please continue. + * + * The library keeps track of the state of nameservers and will avoid + * them when they go down. Otherwise it will round robin between them. + * + * Quick start guide: + * #include "evdns.h" + * void callback(int result, char type, int count, int ttl, + * void *addresses, void *arg); + * evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + * evdns_resolve("www.hostname.com", 0, callback, NULL); + * + * When the lookup is complete the callback function is called. The + * first argument will be one of the DNS_ERR_* defines in evdns.h. + * Hopefully it will be DNS_ERR_NONE, in which case type will be + * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time + * which the data can be cached for (in seconds), addresses will point + * to an array of uint32_t's and arg will be whatever you passed to + * evdns_resolve. + * + * Searching: + * + * In order for this library to be a good replacement for glibc's resolver it + * supports searching. This involves setting a list of default domains, in + * which names will be queried for. The number of dots in the query name + * determines the order in which this list is used. + * + * Searching appears to be a single lookup from the point of view of the API, + * although many DNS queries may be generated from a single call to + * evdns_resolve. Searching can also drastically slow down the resolution + * of names. + * + * To disable searching: + * 1. Never set it up. If you never call evdns_resolv_conf_parse or + * evdns_search_add then no searching will occur. + * + * 2. If you do call evdns_resolv_conf_parse then don't pass + * DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it). + * + * 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag. + * + * The order of searches depends on the number of dots in the name. If the + * number is greater than the ndots setting then the names is first tried + * globally. Otherwise each search domain is appended in turn. + * + * The ndots setting can either be set from a resolv.conf, or by calling + * evdns_search_ndots_set. + * + * For example, with ndots set to 1 (the default) and a search domain list of + * ["myhome.net"]: + * Query: www + * Order: www.myhome.net, www. + * + * Query: www.abc + * Order: www.abc., www.abc.myhome.net + * + * Internals: + * + * Requests are kept in two queues. The first is the inflight queue. In + * this queue requests have an allocated transaction id and nameserver. + * They will soon be transmitted if they haven't already been. + * + * The second is the waiting queue. The size of the inflight ring is + * limited and all other requests wait in waiting queue for space. This + * bounds the number of concurrent requests so that we don't flood the + * nameserver. Several algorithms require a full walk of the inflight + * queue and so bounding its size keeps thing going nicely under huge + * (many thousands of requests) loads. + * + * If a nameserver loses too many requests it is considered down and we + * try not to use it. After a while we send a probe to that nameserver + * (a lookup for google.com) and, if it replies, we consider it working + * again. If the nameserver fails a probe we wait longer to try again + * with the next probe. + */ + +#ifndef EVENT2_DNS_H_INCLUDED_ +#define EVENT2_DNS_H_INCLUDED_ + +#include + +#ifdef __cplusplus +extern "C" { +#endif + +/* For integer types. */ +#include + +/** Error codes 0-5 are as described in RFC 1035. */ +#define DNS_ERR_NONE 0 +/** The name server was unable to interpret the query */ +#define DNS_ERR_FORMAT 1 +/** The name server was unable to process this query due to a problem with the + * name server */ +#define DNS_ERR_SERVERFAILED 2 +/** The domain name does not exist */ +#define DNS_ERR_NOTEXIST 3 +/** The name server does not support the requested kind of query */ +#define DNS_ERR_NOTIMPL 4 +/** The name server refuses to reform the specified operation for policy + * reasons */ +#define DNS_ERR_REFUSED 5 +/** The reply was truncated or ill-formatted */ +#define DNS_ERR_TRUNCATED 65 +/** An unknown error occurred */ +#define DNS_ERR_UNKNOWN 66 +/** Communication with the server timed out */ +#define DNS_ERR_TIMEOUT 67 +/** The request was canceled because the DNS subsystem was shut down. */ +#define DNS_ERR_SHUTDOWN 68 +/** The request was canceled via a call to evdns_cancel_request */ +#define DNS_ERR_CANCEL 69 +/** There were no answers and no error condition in the DNS packet. + * This can happen when you ask for an address that exists, but a record + * type that doesn't. */ +#define DNS_ERR_NODATA 70 + +#define DNS_IPv4_A 1 +#define DNS_PTR 2 +#define DNS_IPv6_AAAA 3 + +#define DNS_QUERY_NO_SEARCH 1 + +#define DNS_OPTION_SEARCH 1 +#define DNS_OPTION_NAMESERVERS 2 +#define DNS_OPTION_MISC 4 +#define DNS_OPTION_HOSTSFILE 8 +#define DNS_OPTIONS_ALL 15 + +/* Obsolete name for DNS_QUERY_NO_SEARCH */ +#define DNS_NO_SEARCH DNS_QUERY_NO_SEARCH + +/** + * The callback that contains the results from a lookup. + * - result is one of the DNS_ERR_* values (DNS_ERR_NONE for success) + * - type is either DNS_IPv4_A or DNS_PTR or DNS_IPv6_AAAA + * - count contains the number of addresses of form type + * - ttl is the number of seconds the resolution may be cached for. + * - addresses needs to be cast according to type.

The Libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, Libevent also support callbacks due + to signals or regular timeouts. + + Libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_base_dispatch() and then add or + remove events dynamically without having to change the event loop. + + + Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2), + epoll(4), and evports. The internal event mechanism is completely + independent of the exposed event API, and a simple update of Libevent can + provide new functionality without having to redesign the applications. As a + result, Libevent allows for portable application development and provides + the most scalable event notification mechanism available on an operating + system. Libevent can also be used for multithreaded programs. Libevent + should compile on Linux, *BSD, Mac OS X, Solaris and, Windows. + + @section usage Standard usage + + Every program that uses Libevent must include the + header, and pass the -levent flag to the linker. (You can instead link + -levent_core if you only want the main event and buffered IO-based code, + and don't want to link any protocol code.) + + @section setup Library setup + + Before you call any other Libevent functions, you need to set up the + library. If you're going to use Libevent from multiple threads in a + multithreaded application, you need to initialize thread support -- + typically by using evthread_use_pthreads() or + evthread_use_windows_threads(). See for more + information. + + This is also the point where you can replace Libevent's memory + management functions with event_set_mem_functions, and enable debug mode + with event_enable_debug_mode(). + + @section base Creating an event base + + Next, you need to create an event_base structure, using event_base_new() + or event_base_new_with_config(). The event_base is responsible for + keeping track of which events are "pending" (that is to say, being + watched to see if they become active) and which events are "active". + Every event is associated with a single event_base. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must create an + event structure with event_new(). (You may also declare an event + structure and call event_assign() to initialize the members of the + structure.) To enable notification, you add the structure to the list + of monitored events by calling event_add(). The event structure must + remain allocated as long as it is active, so it should generally be + allocated on the heap. + + @section loop Dispatching events. + + Finally, you call event_base_dispatch() to loop and dispatch events. + You can also use event_base_loop() for more fine-grained control. + + Currently, only one thread can be dispatching a given event_base at a + time. If you want to run events in multiple threads at once, you can + either have a single event_base whose events add work to a work queue, + or you can create multiple event_base objects. + + @section bufferevent I/O Buffers + + Libevent provides a buffered I/O abstraction on top of the regular event + callbacks. This abstraction is called a bufferevent. A bufferevent + provides input and output buffers that get filled and drained + automatically. The user of a buffered event no longer deals directly + with the I/O, but instead is reading from input and writing to output + buffers. + + Once initialized via bufferevent_socket_new(), the bufferevent structure + can be used repeatedly with bufferevent_enable() and + bufferevent_disable(). Instead of reading and writing directly to a + socket, you would call bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + See for more information. + + @section timers Timers + + Libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_new() macro returns + an event struct to use as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + (These macros are thin wrappers around event_new(), event_add(), + and event_del(); you can also use those instead.) + + @section evdns Asynchronous DNS resolution + + Libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. See the + functions for more detail. + + @section evhttp Event-driven HTTP servers + + Libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the header in your + program. See that header for more information. + + @section evrpc A framework for RPC servers and clients + + Libevent provides a framework for creating RPC servers and clients.

Events come into existence via + * event_assign() or event_new(), and are then neither active nor pending. + * + * To make an event pending, pass it to event_add().
