2015-01-21 Jon McKenzie <jcmcken at gmail.com>
* Version 3.4.0
- Added the --env option to ``pssh``, for use with ``--script``. This
allows the user to pass ``KEY=VALUE`` pairs to inject into the
environment of the executing script. E.g. ``pssh --script
/tmp/some-script.sh --env foo=bar ...etc...``.
2014-04-06 Jon McKenzie <jcmcken at gmail.com>
* Version 3.3.0
- Added the --copy-to option for pssh, which allows you to configure
where the script (--script) gets copied on the remote end.
- If a shebang line exists in the script passed to --script, the script
will be executed using the runtime from that shebang rather than a
straight execution. This fixes an issue where the --copy-to location
is a device mounted with the noexec option.
- Added the --runtime option for pssh, which allows you to manually set
the script (--script) runtime to use.
- Added the --debug option for all p-utilities. Currently not much is
logged, however.
- The --args option now correctly accepts multiple arguments.
- An RPM spec file for Red Hat Enterprise Linux 5/6 (and derivatives)
was added.
2012-12-29 Jon McKenzie <jcmcken at gmail.com>
* Version 3.2.2
- Fixed a bug with --script where pssh would interpret a run as a success when
the script could not be written on the remote side due to a full disk device.
2012-05-04 Jon McKenzie <jcmcken at gmail.com>
* Version 3.2.1
- Added --args companion option for --script, for passing arguments to
the script when run on remote host.
2012-02-05 Jon McKenzie <jcmcken at gmail.com>
* Version 3.1.1
- Fixed a bug with blank lines in host files (Issue #20).
- Fixed Python 2.4 compatibility vis-a-vis the hashlib module. (Issue
#21)
- Fixed Python 2.5/2.6 compatibility vis-a-vis use of the special _sqlite
module. (Issue #22)
2012-01-16 Jon McKenzie <jcmcken at gmail.com>
* Version 3.1.0
- Added PSSH --sudo companion option for --script, which executes the script as root
if user has passwordless sudo permissions.
2012-01-15 Jon McKenzie <jcmcken at gmail.com>
* Version 3.0.0
- Added -s/--summary option, for printing success/failure summary after a run
- Added -B/--progress-bar option, for printing a progress bar instead of task
output.
- Added --sample-size option, for running against a host sample
- Added --host-regexp option, for filtering hosts based on a regular expression
- Added -T/--test option, for splitting up a run so that you can first verify
your command succeeds on a small number of servers before continuing on the rest.
- Added a -F/--fork-hosts option, which outputs all successful hosts to one file and all
failed hosts to another file. Useful for running follow-up tasks
- Added --sqlite-db option for PSSH. After a run, dumps all task data to a sqlite DB.
- Added --pickle-file option for PSSH. After a run, pickles all task data and dumps to file.
- Added --script option for PSSH. Runs supplied script on all remote machines instead of
running the given command.
- Help output for all scripts now uses option groups, making it more readable
- UI functionality split out into its own submodule 'psshlib.ui'
- Host lists are now computed using the ServerPool class in the new submodule
'psshlib.hosts'
- Refactored and minified all scripts. All logic is now implemented in 'psshlib.cli'.
Makes it easy to programmatically call any of the CLIs without hacking at sys.path
- Completely refactored many parts of the API, making things easier to maintain and
extend.
2011-02-02 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.2.2
- Fixed two crashes (issues 35 and 36). One affects Python <= 2.5
and the other affects all of the scripts except pssh.
2011-01-26 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.2.1
- Fixed a crash when the -l option was used in conjunction with a
hosts file (issue #34).
2011-01-21 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.2
- Added a basic man page for pssh (issue #10).
- Fixed askpass to work correctly in the presence of non-password
prompts from ssh (issue #23).
- Updated the -O option so that it can be specified multiple times
(issue #25). Thanks to soham.mehta for the patch.
- Fixed host file loader to give an error instead of a backtrace
if a file is not found.
- Fixed prsync's "-ssh-args" mangling of its argument (issue #24).
Thanks to jbyers for the patch.
- Fixed some variable names to appease pylint. Thanks to solj for
the patch.
- Improved pscp to be able to copy multiple local files. Thanks
to Carlo Marcelo Arenas Belon for the patch.
- Deprecated the PSSH_HOSTS environment variable that seems to
cause more problems than it's worth.
- Added the ability to set multiple hosts with a single -H flag
(issue #26). Thanks to [email protected] for the patch.
- Stopped passing "-q" to ssh by default (this masked error messages
and reduced usability).
- Removed automatic reading from stdin (deprecated in version 2.1).
Please use the "-I" option instead.
- Added meaningful exit status codes (issue #30).
- Other minor fixes
2010-02-26 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.1.1
- Fixed a problem causing PSSH to crash with Python 2.4.
2010-02-24 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.1
- Added support for Python 3.0 and 3.1. Although PSSH has only
been lightly tested with Python 3, anything that doesn't work
in Python 3 is officially a bug.
- Added a "-H" option for specifying hosts one-by-one instead of
or in addition to a hosts file.
- Added "-x" and "-X" options for passing extra command-line
arguments to ssh and rsync. Also added a "-S" option to prsync
for the special case of passing extra arguments to ssh
(issue #2).
- Added a "-I" option for specifying that pssh should read from
standard input, and added a deprecation warning when standard
input is used without this option (issue #12).
- Made the command argument optional when the "-I" option is
given, so a script can be passed to pssh on standard input
(issue #5).
- If a username or port is given, these are now included in the
output filename, which allows different connections to be
distinguished from each other (issue #7).
- Added the pssh-askpass wrapper as a standalone script because
setup.py was removing the executable bit from askpass.py. This
fixes a "permission denied" error when using the -A option
(issue #8).
- Fixed a problem where pssh was unnecessarily specifying a
username (issue #14).
- Fixed a delay due to a lost SIGCHLD signal.
- Removed extra spaces between output chunks in outdir files
(issue #6). Thanks to knutsen for the fix.
- Fixed a bug where pscp passed the wrong option for sending scp
a custom port. Thanks to Jan Rafaj for the patch.
- Fixed prsync to send the port as an option to ssh (issue #1).
Thanks to Ryan Brothers for the fix.
2009-10-20 Andrew McNabb <amcnabb at mcnabbs.org>
* Version 2.0
- Rewrote communication code to be more efficient. PSSH now
operates with only one or two threads.
- Added the ability to interrupt PSSH (with CTRL-c).
- Added an option to prompt for a password.
- Refactored code into a distinct library (psshlib).
2008-10-12 Brent N. Chun <bnc at theether.org>
* Version 1.4.3
- Fixed bug in select_wrap. If timeout is None (e.g., the
default for prsync, etc.), then never time out. Bug reported
by Carlo Marcelo Arenas Belon (carenas at sajinet.com.pe).
- Catch getopt exceptions and print usage as well as getopt
exception string. Contribution from Carlo Marcelo Arenas
Belon (carenas at sajinet.com.pe).
- Added contribution from Bas van der Vlies (basv at sara.nl)
to allow comments in hosts file. Comments must begin with
# character (leading whitespace is also allowed).
- Restore file status bugs after reading stdin in pssh.
- Fixed typo bug in pslurp when using options and in
non-recursive mode.
- Removed conflicts with built-in names.
2008-09-01 Brent N. Chun <bnc at theether.org>
* Version 1.4.2
- Fixed minor bug: select returns select.error on an error,
not OSError.
2008-08-27 Brent N. Chun <bnc at theether.org>
* Version 1.4.1
- Removed broken SIGCHLD handler.
- Refining subprocess _cleanup dynamically to an empty lambda
function since subprocess is not thread-safe and we already
call wait on child processes ourselves anyway.
- Adding missing verbose flag to rest of bin/* programs.
2008-08-24 Brent N. Chun <bnc at theether.org>
* Version 1.4.0
- Fixed 64-bit bug in pslurp, pscp, prsync. Previously, the
default select timeout was sys.maxint, but this is a 64-bit
value on 64-machines. Now using None when calling select when
there is no timeout. Bug reported by (buixor at gmail.com).
- Catching EINTR and ignoring it for select, read, write in
BaseThread class.
- Fixed longopts for pnuke, prsync, pscp, pslurp, pssh (bug
reported a Debian user via Andrew Pollock (apollock at
debian.org)).
Reference: "bug #481901: pssh: options mis-specified"
- Added missing environment variables for options for pnuke,
prsync, pscp, pslurp, pssh.
2008-06-04 Brent N. Chun <bnc at theether.org>

- Switched to BSD license.
2006-06-18 Brent N. Chun <bnc at theether.org>
* Version 1.2.2
- Added patch from Dan Silverstein (dans at pch.net) to fix
parsecmdline bug.
2005-12-31 Brent N. Chun <bnc at theether.org>
* Version 1.2.1
- Changed sys.path so pssh can run without RPM
install.
- Changed RPM library files to install in
/usr/local/lib/python

expected for installations from source.
2004-11-10 Brent N. Chun <bnc at intel-research.net>
