- This file describes changes in recent versions of pdsh. It primarily
- documents those changes that are of interest to users and admins.
- * Changes in pdsh-2.28 (2011-10-19)
- ===================================
- -- Fix issue 39: ssh forces use of -l<user> option
- -- Fix issue 40: -l%u added to ssh args only if remote and local
- usernames differ
- -- testsuite: Added tests for -l%u handing in ssh
- * Changes in pdsh-2.27 (2011-09-07)
- ===================================
- -- Fix issue 17: Allow dshgroup files to include other files
- -- Fix issue 33: dshbak breaks up host lists at zeropad boundaries,
- (e.g. 01-09,10-11, 010-099,100-101, etc.)
- -- Fix issue 34: dshgroup path override broken in ./configure
- -- Fix issue 36: pdsh truncates output lines at 8K
- -- dshgroup: Allow dshgroup search path to be overridden by DSHGROUP_PATH,
- a colon-separated list of directories to search. $HOME/.dsh/group
- is still always prepended to this path.
- -- Allow wcoll files (-w ^file and WCOLL=file) to include other files
- with a "#include FILE" syntax. If included files have no path, then
- a search path of the dirname of the included file ("." for stdin)
- is used.
- -- testsuite: added tests, fixed some portability issues.
- -- Fix some minor memory leaks and locking bugs reported by Coverity.
- * Changes in pdsh-2.26 (2011-04-29)
- ===================================
- -- Fix issue 14: interactive mode broken with ssh
- -- Fix issue 19: missing commas in dshbak(1) header output
- -- Fix issue 20: compilation error in genders.c with non-GCC compilers
- -- Fix issue 23: compilation failure with --enable-static-modules
- -- Fix issue 24: don't arbitrarily limit usernames to 16 characters
- -- Fix issue 25: PDSH_SSH_ARGS should not require %u and %h
- -- Fix issue 26: document use of %u and %h in PDSH_SSH_ARGS
- -- Fix interactive mode with rcmd/exec.
- -- genders: do not look for genders_query(3) support at runtime,
- as this causes too many problems on some systems. Instead,
- use autoconf to include or exclude genders_query support from
- the genders module. (fixes Issue 1)
- -- Fix build on AIX
- -- Add -Wl,-E to LDFLAGS on HP-UX (Issue 18)
- -- Fixes for testsuite portability (Issues 15, 22, 28)
- * Changes in pdsh-2.25 (2011-03-09)
- ===================================
- -- Fix pdcp breakage with ssh (bug introduced in pdsh-2.24).
- (Resolves issue 12: pdcp executes file instead of copying.)
- -- testsuite: Skip tests dependent on PDSH_MODULE_DIR when testsuite
- run as root (Resolves issue 13: testsuite broken when run as root).
- -- testsuite: Skip dshbak -d test to non-writable directory when
- directory permissions do not seem to apply (e.g. privileged user).
- (Possibly resolves issue 11: tests fail on Mac OSX under fink)
- -- testsuite: add simple ssh tests.
- * Changes in pdsh-2.24 (2011-02-28)
- ===================================
- -- Resolve issue 7: Allow PDSH_REMOTE_PDCP_PATH to set default path
- to remote pdcp program (pdcp -e).
- -- Resolve issue 9: Fix use of PDSH_SSH_ARGS_APPEND.
- -- Resolve issue 10: dshbak: Support writing output to file-per-host.
- Adds new -d DIR and -f options to dshbak.
- -- genders: Allow relative paths to genders files with -F and
- PDSH_GENDERS_FILE.
- -- genders: Don't print an error if genders file is missing, unless
- a genders optin (-F, -a, -g, -i, -X) is explicitly used.
- -- genders: Allow -g to be used with other node selection options as
- a filter. For example: pdsh -w host[0-1024] -g attr1 ...
- -- ssh: Better preservation of remote command args in ssh module.
- Previous versions of pdsh would alwas collapse all args into
- a single argument passed to ssh: "cmd arg1 arg2 ..." With this
- fix the argv list will more closely match the form passed to pdsh.
- -- Refactored large portions of dshbak, improve usage output,
- and update manpage.
- -- Expanded testsuite.
- * Changes in pdsh-2.23 (2010-10-22)
- ===================================
- -- Fix issue 4: List available but conflicting modules in -V and -L output.
- -- Fix issue 5: dshbak -c doesn't properly coalesce hosts with different
- zero-padding in the numeric suffix.
- -- Added torque module for setting list of target hosts based on Torque/PBS
- jobs (Issue 2).
- -- Enhance syntax of -w and -x to allow preceeding arguments with:
- `-' - Exclude hosts instead of include with -w ( -w foo[1-9],-foo8)
- `^' - insert/exclude list of hosts from a file (^/path/to/file)
- `/' - filter hosts based on regex (/host.*0$/)
- -- Introduce new pdsh testsuite with many new tests. See tests/README
- for more information.
- * Changes in pdsh-2.22 (2010-09-03)
- ===================================
- -- Fixes several bugs introduced in pdsh-2.21, Including:
- - genders: segfault when genders file doesn't exist
- - Failure to initialize some modules if others conflict
- - -M option doesn't work in some cases
- -- Sort modules by name before initialization so that modules
- initialize in a reproducible order.
- * Changes in pdsh-2.21 (2010-09-02)
- ===================================
- -- New option -M name,... forces load of misc modules by
- name, thus allowing users to select between conflicting
- modules. (PDSH_MISC_MODULES environment variable may
- also be used)
- -- Due to above, an error is no longer printed when module
- options conflict.
- -- genders: Support PDSH_GENDERS_FILE environment variable to
- override default genders file name (default = "genders")
- -- genders: Support PDSH_GENDERS_DIR environment variable to
- override default directory for genders files (default = /etc).
- -- genders: Allow non-absolute path to be specified to -F option.
- -- Fix parsing of hostlist expressions with multiple brackets
- (from SF.net user don.fanucci)
- -- Fix compile error on platforms where setnetgrent() doesn't
- return an int.
- -- Allow path to dshgroup files to be specified to ./configure
- with --with-dshgroups=PATH.
- -- Update libltdl
- * Changes in pdsh-2.20 (2009-09-29)
- ===================================
- -- Fix bug in pdcp which serialized copy of files to nodes
- regardless of fanout.
- * Changes in pdsh-2.19 (2009-05-21)
- ===================================
- -- New pdsh configure option --with-rcmd-rank-list allows
- the default pdsh rcmd module priority list to be overridden
- at compile time.
- -- genders: Always read genders file in case there are any
- pdsh_rcmd_type attributes to apply to the target hosts.
- -- genders: Fix bug where altnames were not used by default
- in some cases due to a bug in generic module loading code.
- (patch from Py Watson)
- -- Fix for coredump when no rcmd module is loaded.
- (patch from Py Watson)
- -- %{_libdir}/pdsh should be owned by pdsh RPM.
- (patch from Py Watson)
- * Changes in pdsh-2.18 (2009-03-24)
- ===================================
- -- Fix duplicate error output from ssh module.
- (Patch from Paul D Smith <psmith at users.sourceforge.net>)
- -- Add -e option to pdcp to explicitly specify remote execution path.
- This is necessary if pdcp is installed in a different path locally
- than on the target hosts.
- -- Fix recursive pdcp (-r) which has been broken since pdsh-2.12.
- -- Support --without-ssh-connect-timeout-option for ./configure.
- -- Add note to pdsh(1) manpage that only very old versions of
- the genders nodeattr script are supported by the pdsh nodeattr
- module. The genders module is the preferred interface to genders.
- * Changes in pdsh-2.17 (2008-09-23)
- ===================================
- -- Ignore multiple consecutive ':' characters in host list argument to
- -w option. Only a single ':' by itself will be interpreted as the
- special "rcmd_type:hosts" syntax.
- -- dshbak: Allow for ':' in pdsh output lines.
- (patch from Ashley Pittman)
- -- Fix for compile against glibc 2.8, which no longer defines ARG_MAX
- (patch from Tom 'spot' Callaway via sf.net).
- -- Include missing unistd.h in hostlist.h.
- (patch from Ashley Pittman)
- -- Fix compile on Solaris by updating to latest ACX_PTHREAD autoconf
- macro from autoconf-archive.cryp.to.
- * Changes in pdsh-2.16 (2008-03-19)
- ===================================
- -- Don't attempt to read WCOLL file unless no other host
- selection method is utilized.
- -- (genders) Don't attempt to read a genders file if no genders
- options are used.
- -- When specifying rcmd_type via -w (i.e. [rcmd_type:][user@]host)
- have rcmd_type apply across all hosts until the next rcmd
- specification. That is ssh:host1,host2 now uses ssh for both
- host1 and host2. Prior to this change, ssh would only be used
- to contact host1. Same change for [user].
- -- Check for valid fanout specified to -f option.
- -- Always sort output of dshbak, and remove dshbak -s option.
- -- Strip leading space (added by pdsh) from dsbak output.
- * Changes in pdsh-2.15 (2007-10-24)
- ===================================
- -- Refactor ssh module to use built in "pipecmd" support
- (same code as the "exec" module)
- -- Add connect timeout support for ssh implementations which support it.
- By default, the OpenSSH "-oConnectTimeout=%d" option is used. This
- can be overridden at configure time using
- --with-ssh-connect-timeout-option="OPTION"
- where OPTION should contain one %d which will be expanded to the
- actual timeout value specified on the command line.
- -- Add ncurses-devel to pdsh.spec BuildRequires.
- * Changes in pdsh-2.14 (2007-06-22)
- ===================================
- -- Fix compile error in src/pdsh/mod.c when using --enable-static-modules.
- -- Allow conditional and static build of "exec" rcmd module.
- -- (slurm) Re-order headers in slurm module to avoid redefinition
- of pdsh bool type.
- * Changes in pdsh-2.13 (2007-06-06)
- ===================================
- -- New "exec" rcmd module for executing arbitrary commands.
- (Thanks to Christopher Maestas <cdmaest at sandia dot gov>
- for the idea.)
- -- New -N option to disable hostname: prefix on lines of output.
- -- dshbak: Allow host range compression for numerically keyed hosts
- which have non-numeric suffix.
- -- Fix for compilation problem on some machines for sshcmd.c.
- -- Fix for erroneous command timeouts with ssh due to stray signals.
- -- Fix handling of empty lines when parsing WCOLL files.
- * Changes in pdsh-2.12 (2006-12-11)
- ===================================
- -- Fix Solaris build.
- -- New command rpdcp(1) ("reverse" pdcp) copies files from remote
- hosts to the local machine (with remote hostname appended).
- -- Do not truncate host domain in output labels if any domains differ.
- -- (genders) Default user name may be specified to pdsh_rcmd_type attr
- by prepending "user@".
- -- (slurm) `-j' "all" parameter to target all nodes running SLURM jobs.
- -- (slurm) Fix for build issue against slurm-1.0.
- -- Minor code cleanup.
- -- Minor RPM spec file cleanup.
- * Changes in pdsh-2.11 (2006-07-26)
- ===================================
- -- Fix for WCOLL file contents unconditionally added to host list.
- Prior behavior was to have -w override WCOLL.
- -- Supply more specific errors when pdsh detects that the path to
- pdsh modules is insecure.
- -- Fix man page typos.
- -- Fix compile for Tru64.
- -- (xcpu) Use lexec facility.
- -- New dshbak -s option to sort output.
- -- Allow users to cancel pending threads by issuing ctrl-C ctrl-Z
- (ctrl-Z within one second of initial ctrl-C). Pending threads
- are those threads which have not yet invoked a remote command.
- * Changes in pdsh-2.10 (2006-03-22)
- ===================================
- -- Fix for -w hosts parsing bug.
- -- Fix missing support for "-w user@hosts" in pdsh-2.9.
- -- Add support for command history in interactive mode with readline.
- Command history file is ~/.pdsh/history.
- -- (xcpu) Support for signals and -S.
-
- * Changes in pdsh-2.9 (2006-03-15)
- ===================================
- -- Add netgroup module which provides -g/-X groupname option to read
- list of hosts from netgroup entries (/etc/netgroup or NIS).
- -- Add support for specifying alternate rcmd connection type and/or
- remote username for a subset of hosts on the commandline. Format
- is ``-w [rcmd_type:][user@]hosts...''
- -- (genders) Add support for pdsh_rcmd_type genders attribute to set
- the default rcmd connection type for certain hosts via the genders
- database.
- -- Add a trivial form of privilege separation to pdsh when pdsh or pdcp
- binaries are installed setuid root. This is necessary to safely support
- multiple rcmd connection methods in a single invocation of pdsh.
- Currently, the privileged process in pdsh is only used to serve reserved
- ports to threads that need it (e.g. rsh, qsh), while allowing all threads
- to still run as the "user" to support ssh and mrsh. This is *not*
- a security enhancement, and doesn't make installing pdsh setuid root
- any more secure.
- -- (ssh) Allow arguments to ssh command to be overridden and augmented
- with environment variables PDSH_SSH_ARGS and PDSH_SSH_ARGS_APPEND.
- -- Fix for race condition in ssh support which caused occasional pdsh
- hang, especially when running with a larger fanout.
- -- Fix for ``-x hosts'' processing bug: occasionally hosts provided to
- -x option would not be removed from the list of targets because the
- list of excluded hosts was being processed too early.
- -- Fixes for Mac OSX support: Update libtool/ltmain.sh and test for
- and include sys/uio.h.
- -- Add support for LANL XCPU.
- * Changes in pdsh-2.8 (2005-10-13)
- ===================================
- -- (dshgroup) Fix bug in dshgroup module which resulted in the module
- trying to read only from ~/.dsh/group/ even if /etc/dsh/group/
- should have been used. (patch from Joe Ramey <ramey@it.com>)
- -- Print error strings returned by remote RCP server instead of generic
- "Failed to initiate RCP protocol."
- -- Allow hostlist expressions to have suffixes (e.g. foo[0-10]-bar).
- -- Fix for command timeout when its value is less than connect timeout.
- -- (ssh) Remove ssh_reaper thread and instead reap child ssh processes
- within each thread spawned by pdsh. This fixes reported problem
- under LinuxThreads.
- -- (sdr) Fix assertion failure if host_responds info exists in SDR
- for a node number that doesn't exist in Node class.
- * Changes in pdsh-2.7 (2005-08-15)
- ===================================
- -- Add dshgroup module which adds -g/-X groupname to utilize dsh-style
- "group" files in ~/.dsh/group/groupname || /etc/dsh/group/groupname.
- -- Fix possible truncation of output when poll() returns POLLHUP before
- all data has been read.
- -- Close pdsh file descriptors opened to ssh commands before invoking
- subsequent ssh connections to fix possible pdsh hang with -Rssh.
- -- Replace setenv() & seteuid() with putenv() & setuid() for portability.
- -- Module path elements now considered secure if they have same ownership
- as pdsh binary (as well as either root or current user). Allows pdsh
- to be installed with other than root ownership.
- * Changes in pdsh-2.6 (2005-08-02)
- ===================================
- -- (ssh) Fix pdcp hang with ssh on HP-UX (and possibly other systems).
- (Yehia Beyh <Yehia.Beyh@hp.com>)
- -- Remove pdcp debugging code released with pdsh-2.5.
- * Changes in pdsh-2.5 (2005-07-21)
- ===================================
- -- (ssh) Added ssh "reaper" thread to collect exit status of ssh commands
- invoked by pdsh. At the end of the pdsh or pdcp run, any non-zero
- exit status from ssh will be written to stderr instead of silently
- ignored.
- -- (genders) Added genders "query" support for genders versions that
- support this functionality. (Al Chu <chu11@llnl.gov>)
- -- (ssh) Fix for a possible pdsh hang when running with ssh on Mac OS X.
- -- (qshell) Fix for m/qshd failure on nodes without an elan3 adapter.
- (Daniel Blueman <daniel.blueman@quadrics.com>)
- -- Update path to xinetd script in pdsh specfile (Daniel Blueman).
- -- Don't increase number of open files rlimit until after rcmd modules
- are initialized in case rcmd module increases fanout.
- -- Don't consider directory permissions insecure when other has write
- access if the sticky bit is set.
- * Changes in pdsh-2.4 (2004-12-08)
- ===================================
- -- (mrsh) Update to mrsh protocol version 2.1, provided by mrsh >= 2.3.
- This version of the protocol allows connections over "localhost."
- * Changes in pdsh-2.3 (2004-11-22)
- ===================================
- -- Support copying files >2GB in pdcp.
- -- Increase max number of open files to the hard limit if
- a large fanout is requested.
- * Changes in pdsh-2.2 (2004-07-30)
- ===================================
- -- Do not abort when excluded hosts are not within the target list.
- -- (slurm) Allow multiple SLURM jobids to be passed to -j option.
- * Changes in pdsh-2.1 (2004-06-09)
- ===================================
- -- Fix dshbak script to allow whitespace in hostname "tags"
- (Ashley Pittman <ashley@quadrics.com>).
- -- Fix broken QsNet support on Elan3 systems without libelanctrl.
- -- Explicitly set thread stack size to 128K to avoid arbitrarily
- large stack set from current rlimit under Linux/NPTL.
- * Changes in pdsh-2.0 (2004-05-26)
- ===================================
- -- Reorganized pdsh source tree.
- -- Modularized pdsh functionality into dynamic runtime "modules."
- - Moved remote command api (e.g. rsh, ssh, etc.) into "rcmd" modules.
- - New pdsh option `-R' for selection of rcmd type at runtime.
- - All other optional functionality moved into "misc" modules (e.g. genders).
- - See README.modules in pdsh distribution for more information.
- -- Package core pdsh functionality and pdsh modules separately in order to
- make pdsh installation much more flexible.
- -- Removed pdsh dependency on rcp. Rcp server code used by pdsh is now
- coded directly into pdcp. (Note: This means pdcp *must* be installed
- on all target nodes)
- -- Added mrsh and mqshell client modules, as well as mqshd server for Munge
- authenticated rcmd() support.
- -- Added SLURM module to build list of targets from SLURM allocations.
- -- (genders) Added "-X" option to exclude targets based on genders attributes.
- -- (genders) Multiple attributes may now be passed to "-g" and "-X."
- -- (genders) "-a" renamed to "-A" -- "-a" now skips any nodes in genders
- database with "pdsh_all_skip" attribute.
- -- (genders) New "-F" option to specify non-default genders file.
- -- QsNet support now requires "/etc/elanhosts" config file (see README.QsNet).
- -- QsNet support includes support for QSW elanctrl interface. (Elan3/Elan4)
- -- Added support for running Elan network error resolver thread in qshd/mqshd.
- (Elan3 only)
- -- Nominal support for Elan multirail jobs (largely untested). See
- qshell and mqshell `-r railmask' option.
