2015-07-07 S. Thiell <sthiell@stanford.edu>
* CLI/Nodeset.py: add --autostep=auto and --autostep=x% option (#161).
* NodeSet: add autostep property to allow changing the way every RangeSet of
a NodeSet object is displayed (eg. node[2-8/2] instead of node[2,4,6,8]).
Autostep value is the min number of indexes that are found at equal distance
of each other inside a range before NodeSet starts to use this syntax.
2015-05-18 S. Thiell <stephane.thiell@cea.fr>
* Version 1.6.92 released.
2015-04-10 S. Thiell <stephane.thiell@cea.fr>
* Tree: implement task.copy() in tree mode using temporary tar file.
2015-04-01 S. Thiell <stephane.thiell@cea.fr>
* Tree: allow local command execution on gateways by adding remote=False to
task.shell()/run(). In practice with this patch, we can now easily
execute local commands on (remote) gateways using node argument like
`ipmitool -H %h` to spread the load between gateways.
2015-03-24 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: disallow opening bracket after digit (ticket #228).
2015-03-23 S. Thiell <stephane.thiell@cea.fr>
* Clush.py: Warn user of possible use of shell globbing, especially when
using brackets and bash without GLOBIGNORE set (ticket #225).
* Clush.py: Fix --diff against null content (ticket #214).
2015-03-19 S. Thiell <stephane.thiell@cea.fr>
* Task.py: Make max_retcode() return None on no-op. Until now, max_retcode()
returned 0 by default, so even when no command was able to finish (for
example, due to reached timeout). This behavior did not allow users to
distinguish between successful commands and such no-op.
2015-03-11 S. Thiell <stephane.thiell@cea.fr>
* Worker.py: Introduce StreamWorker as a generic worker class to manage a
set of streams (using one EngineClient with multiple I/O streams
internally). It's a concrete class that is now used in Gateway.py to
manage I/O from the parent host in tree propagation mode. Also changed
WorkerSimple (and thus WorkerPopen) to inherit from StreamWorker.
2014-05-20 S. Thiell <stephane.thiell@cea.fr>
* EngineClient.py: Code improvement to support multiple customizable I/O
streams per EngineClient in different mode, each being named and having
their own read/write buffers and attributes.
2014-04-30 A. Degremont <aurelien.degremont@cea.fr>
* Clush.py: Add a 'worker' option to switch default worker (ticket #221).
2014-04-23 S. Thiell <stephane.thiell@cea.fr>
* EPoll.py: Close epoll control file descriptor when engine is released.
2014-01-26 A. Degremont <aurelien.degremont@cea.fr>
* NodeUtils.py: Add group source caching expiration (ticket #98).
2014-01-16 S. Thiell <stephane.thiell@cea.fr>
* RangeSet.py: Multidimensional RangeSet support (new RangeSetND class).
Created RangeSetND class to manage a matrix of RangeSet objects. Folding
of such objects is quite complex and time consuming. A special
optimization is provided when only one dimension is varying. Patch by
aurelien.degremont@cea.fr and stephane.thiell@cea.fr.
* NodeSet.py: Multidimensional nodeset support. Added support of
RangeSetND to NodeSet. Optimized NodeSet so that 1D NodeSet objects are
still using RangeSet (ticket #92). Also benefiting from RangeSetND
optimization when only one dimension is varying. Patch by
aurelien.degremont@cea.fr and stephane.thiell@cea.fr.
2014-01-14 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: fix and clean fromall()/@* magic and add resolver option to
grouplist()'s NodeSet module function.
2014-01-14 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Define module API to access and set group resolver used for
@-prefixed (eg. '@group') resolution. This is used to circumvent accessing
and setting NodeSet module's variable 'RESOLVER_STD_GROUP' directly, which
is not convenient and error prone. The new functions are
std_group_resolver() and set_std_group_resolver(). Updated User Guide.
* CLI/Clush.py: ignore IOError on stdin reader thread, but print a warning
in verbose or debug mode (ticket #201).
2014-01-06 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Fix internal implementation of NodeSet.contiguous(), that
is, as NodeSet is mutable, we should avoid using the same NodeSet instance
in NodeSet.contiguous() for different NodeSet values.
2013-12-17 S. Thiell <stephane.thiell@cea.fr>
* Task.py: fix task.iter_buffers() and worker.iter_buffers() to allow
optional argument match_keys to be an empty list for convenience. It
should be set to None to disable match_keys check. Also check that
match_keys is a true key/node sequence and not a string.
2013-11-05 S. Thiell <stephane.thiell@cea.fr>
* EngineClient.py: Hide unwanted debug messages: when aborting a task,
cleanup of associated resources may lead to dropped inter-task messages
through the EnginePort mechanism. We now only display associated warning
messages when debugging is enabled...
* Task.py: Fix abort() race condition.
* CLI/Clush.py: Fix a defect to allow the use of command timeout when
copying files (with clush -u delay -c ..., ticket #220).
2013-11-04 A. Degremont <aurelien.degremont@cea.fr>
* Worker/Rsh.py: Add a Rsh worker. It is compatible with rsh clones
like mrsh/krsh. (ticket #216).
* Task.py: Add a 'worker' default option for Task object. It is used
in Task.shell() and Task.copy().
2012-09-13 S. Thiell <stephane.thiell@cea.fr>
* Engine.py: Allow EngineTimer with immediate fire date, that is, a fire
delay of 0s. Obviously not fired in time, such a timer will still be armed
and fired as soon as possible (ticket #200).
2012-08-27 S. Thiell <stephane.thiell@cea.fr>
* Engine.py: Fix catch-all used in case of KeyboardInterrupt exception
during runloop, resulting in ghost engine clients in that case and results
possibly not cleaned properly (ticket #199).
2012-08-01 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Fix clush_exit() side effects thanks to latest task
termination improvements (tickets #185).
* Task.py: Avoid termination race condition when using multiple threads
and calling abort()+join() from another thread (tickets #197).
2012-07-09 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: "All nodes" extended pattern support with @* (ticket #193).
2012-04-08 S. Thiell <stephane.thiell@cea.fr>
* Version 1.6 released.
* doc/guide: Add ClusterShell User and Programming Guide LaTeX source to
repository.
2012-04-07 S. Thiell <stephane.thiell@cea.fr>
* doc/examples/check_nodes.py: Add simple example of event-driven script.
2012-03-31 S. Thiell <stephane.thiell@cea.fr>
* CLI/Nodeset.py: Allow -a and common nodeset operations when using -l to

to allow a more generic usage of clubak, ie. even in cases where keys are
not nodeset compliant (ticket #180).
2012-03-21 S. Thiell <stephane.thiell@cea.fr>
* conf/groups.conf: Fix group cross reference issue (ticket #183), we now
use sed commands instead of awk ones in this default groups.conf file.
2012-03-18 S. Thiell <stephane.thiell@cea.fr>
* conf/groups.conf: Fix default source regexp for mawk (ticket #178).

variables from the root node.
* Communication.py: Messages are now transfered in xml payload instead of
'output' attribute for improved handling of multi-lines messages in
StdOutMessage and StdErrMessage.
2012-02-24 S. Thiell <stephane.thiell@cea.fr>
* Worker/EngineClient.py: Fix gateway write performance issue, as seen on a
very large cluster with a no-grooming test case and lots of small messages
sent, by calling os.write() as soon as possible (might safely fail if not
ready as we are in non-blocking mode).
* NodeSet.py: Internal parsing optimization by adding a "should copy
RangeSet object?" flag to NodeSetBase constructor in order to save useless
but slightly costly RangeSet.copy() calls.
* NodeSet.py: Small rangeset parsing optimization on single node string
parsing code.
2012-02-19 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Add NodeSet.nsiter(), a fast iterator on nodes as NodeSet
objects to avoid object-to-string-to-object conversion in some cases when
using __iter__() -- like in PropagationTreeRouter.dispatch().
2012-02-15 S. Thiell <stephane.thiell@cea.fr>
* Clush.py: Add --topology <file> hidden option to enable V2 tree
propagation technology preview.
2012-02-01 S. Thiell <stephane.thiell@cea.fr>
* RangeSet.py: Fix RangeSet.__setstate__() for proper object unpickling
from older RangeSet versions. Add unpickling tests.
2012-01-28 S. Thiell <stephane.thiell@cea.fr>
* RangeSet.py: Discard AVL-tree based implementation, as we noticed that
built-in set is much faster. New implementation is based on built-in set,
and slightly changes padding and __iter__() behaviors. Padding value is
now accessible and settable at any time via a public variable "padding".
Auto-detection of padding is still available, but it is used as a
convenience for printing range sets. Moreover, all set-like operations are
now only based on integers, ignoring RangeSet's padding value. __iter__()
has been changed in order to iterate over sorted inner set integers,
instead of string items. A new method striter() is available to iterate
over string padding-enabled items. These changes allow us to offer a full
set-like API for RangeSet (new methods like isdisjoint(), pop(), etc. are
available according to your Python version). Also, a new constructor that
take any iterable of integers is available. Finally, this implementation
should much more faster than all previous ones, especially for large range
sets (ten thousand and more) with lots of holes.
2012-01-10 S. Thiell <stephane.thiell@cea.fr>
* RangeSet.py: Move RangeSet class from NodeSet.py to this new module
dedicated to scalable management of cluster range sets (tens of thousands
of disjoint ranges). Change internal algorithm used to manage ranges from
a list to an AVL-tree based on bintrees project's avltree implementation.
Got rid of expand/fold() methods that don't scale, all sets-like methods
have been rewritten using AVL-tree.
2012-01-04 S. Thiell <stephane.thiell@cea.fr>
* Task.py: Change behavior of shell()'s tree=None (auto) parameter: added
Task default parameter "auto_tree" defaulting to False and checked by
shell() when tree=None. This means that even with a valid topology
configuration file, the user has to explicitly enable tree mode for now.
This is for next 1.6 release and should be changed to True in version 2.0.
2011-11-28 S. Thiell <stephane.thiell@cea.fr>
* Task.py: Fix 'tree' option of shell(), which can be either True (force
enable tree mode), False (disable tree mode) and None (automatic).
2011-11-24 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Enable tree mode by default with grooming option.

to enable preloading of whole messages to speed up processing, but with
an increase of memory consumption (ticket #131).
2011-05-31 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Optimized NodeSet.fromlist() method by adding updaten()
method which is quite O(num_patterns).

autostep not being taken into account (ticket #150).
* Worker/Ssh.py: Fix scp user option in Scp class (ticket #152).
* Engine/*.py: Internal engine design change: do not retry engine
eventloop on any EngineClient registration changes, so process more events
by chunk (should be faster) and add a loop iteration counter to work
around internally re-used FDs (finalize ticket #153).
2011-05-26 S. Thiell <stephane.thiell@cea.fr>

module (trac ticket #41). Improved parser to support basic node/nodegroups
arithmetics (trac ticket #44).
* NodeUtils.py: New module that provides binding support to external node
group sources (trac ticket #43).
2010-03-05 S. Thiell <stephane.thiell@cea.fr>
* Worker/*.py: Do not forget to keep last line and generate an ev_read
event when it does not contain EOL (trac ticket #66). Added tests.
2010-02-26 S. Thiell <stephane.thiell@cea.fr>
* Version 1.2 RC 1 released.
2010-02-25 S. Thiell <stephane.thiell@cea.fr>
* Important code cleaning (use absolute imports, remove some unused
imports, remove duplicate code, etc. thanks to pylint).
2010-02-22 S. Thiell <stephane.thiell@cea.fr>
* scripts/nodeset.py: Change command syntax: operations are now specified
inline between nodesets (trac ticket #45). Update doc and tests.
* scripts/clubak.py: Fix TypeError exception raised on unexpected input
and accept 'node:message' line pattern (trac ticket #59).
* scripts/clush.py: Add -B flag (trac ticket #60) to gather with stderr.
* NodeSet.py: NodeSet constructor now raises a NodeSetParseError
exception when unsupported type is used as input (trac ticket #53).
2010-02-21 S. Thiell <stephane.thiell@cea.fr>
* Task.py: Fix a deadlock when a task is resumed two times from another
thread (raise AlreadyRunningError instead). Added test.
* Worker/Worker.py: Improve usage error handling for some methods (trac
ticket #28), raising WorkerError when needed. Add library misusage tests.
2010-02-18 S. Thiell <stephane.thiell@cea.fr>
* scripts/clush.py: Disable MsgTree buffering when not performing
any gathering of results (when -b is not used).
* Task.py: Allow disabling of MsgTree buffering (trac ticket #3) via
'stdout_msgtree" and 'stderr_msgtree' Task default keywords, useful if we
don't want MsgTree internal buffering for fully event-based scripts (eg.
clush without -b). When disabled, any Task method accessing MsgTree data
like iter_buffers() will raise a new exception (TaskMsgTreeError).
2010-02-17 S. Thiell <stephane.thiell@cea.fr>
* Version 1.2 beta 5 released.
2010-02-16 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Fix mixed-type comparisons, where, like standard set(),
are allowed, instead of raising TypeError.
2010-02-15 S. Thiell <stephane.thiell@cea.fr>
* Version 1.2 beta 4 released.
* MsgTree.py: Added MsgTreeElem.splitlines() method as alias of lines().
2010-02-14 S. Thiell <stephane.thiell@cea.fr>
* Updated doc/man pages for latest clush changes and added clubak tool.
* Worker/Ssh.py: Fix Ssh worker issue where sometimes stderr buffer could
not be read completely (trac ticket #50).
2010-02-13 S. Thiell <stephane.thiell@cea.fr>
* scripts/clush.py: Comply with clubak by adding -L option that allow
switching to alternative line mode display (when using -b). Also, sort
buffers by nodes or nodeset length like clubak (fix trac ticket #54).
2010-02-11 S. Thiell <stephane.thiell@cea.fr>
* Version 1.2 beta 3 released.
* scripts/clush.py: For clush --copy, when --dest is not specified, set
the destination path to the source dirname path and not the source full
path.
* scripts/clush.py: Added option --nostdin to prevent reading from
standard input (fix trac ticket #49).
* Engine/Factory.py: Disable Engine.EPoll automatic selection as an issue
has been found with clush when stdin is a plain file (<file redirections).
Engine.Poll is now the default engine for all platforms. Created trac
ticket #56 to follow this issue.
2010-02-10 S. Thiell <stephane.thiell@cea.fr>
* Worker/Worker.py: Added missing WorkerSimple.last_error() method. Fixed
worker bad argument error exception.
* Worker/Ssh.py: Added command, source and dest public instance variable.
* Worker/Pdsh.py: Added command, source and dest public instance variable.
* scripts/clush.py: Due to set_info() behaviour modifications in
multi-thread mode, change some set_info() for set_default() to modify
task specific dictionary synchronously. Also remove splitlines() where
MsgTreeElem are returned instead of whole buffer after latest MsgTree
improvements.
* scripts/clubak.py: Added clubak utility (trac ticket #47). It provides
dshbak backward-compatibility, but always try to sort buffers by nodes or
nodeset. It also provides additional -L option to switch to alternative
line mode display.
2010-02-09 S. Thiell <stephane.thiell@cea.fr>
* Worker.py: Updated Task/MsgTree dependencies. Added iter_node_errors()
method. Added match_keys optional parameter to iter_node_buffers() and
iter_node_errors(). Added WorkerSimple.error() method (read stderr).
Added tests.
* Task.py: Updated MsgTree dependencies. Factorized most tree data's
access methods.
* MsgTree.py: Merged Msg and _MsgTreeElem in one class MsgTreeElem. All
message objects returned are now instance of MsgTreeElem. Some algorithms
improvements. Renamed main MsgTree access methods: messages(), items() and
walk(). Added more docstring.
* NodeSet.py: Modified NodeSet.__iter__() and __str__() so that nodes are
now always sorted by name/pattern (eg. acluster2, bcluster1).
2010-02-07 S. Thiell <stephane.thiell@cea.fr>
* MsgTree.py: Rewrite of MsgTree module with a better API (part of trac
ticket #47). Adapted library classes. Added specific tests.
2010-02-02 S. Thiell <stephane.thiell@cea.fr>
* Task.py: Add Task.key_error() and its alias node_error() methods for
easy retrieving of error buffers for a specified key/node.
* scripts/clush.py: Fix stdout/stderr separation issue (introduced
in 1.2b2) thanks to the new Task.set_default() method.
* Task.py: As set_info() is now dispatched through the task special port,
and applied only on task.resume() when called from another thread, add two
new methods default() and set_default() to synchronously manage another
task specific dictionary, useful for default configuration parameters.
