2016-10-04 S. Thiell <sthiell@stanford.edu>
* setup.py: remove scripts/*; use console_scripts instead.
2016-10-02 S. Thiell <sthiell@stanford.edu>
* Tree.py: in copy mode, do not send tar data to local targets, but only
remote ones; this does fix broken pipe errors (ticket #319).
* Engine.py: implement basic per worker fanout (private), allowing the use
of fanout=1 in tree mode (ticket #322).
2016-06-18 S. Thiell <sthiell@stanford.edu>
* Version 1.7.2 released.
2016-06-07 D. Martinet <dominique.martinet@cea.fr>

objects (ticket #294).
2016-02-28 S. Thiell <sthiell@stanford.edu>
* Version 1.7.1 released.
2016-02-27 S. Thiell <sthiell@stanford.edu>
* Worker/Tree.py: implement tree mode reverse copy using tar commands to
fix clush --rcopy (ticket #290).
* Communication.py: remove 76-char base64 encoding fixed length
restriction for tree XML payload communication. The default max length is
now 64K, which gives good results. The environment variable
'CLUSTERSHELL_GW_B64_LINE_LENGTH' is propagated to gateways and may be
used to override this value.
2016-02-12 S. Thiell <sthiell@stanford.edu>
* RangeSet.py and NodeSet.py: fix bad 0-padding handling by RangeSetND or
NodeSet objects in nD (ticket #286).
2016-02-09 S. Thiell <sthiell@stanford.edu>
* NodeSet.py: fix parser issue when brackets were used with nodeset
starting with a digit (ticket #284).
2015-11-30 S. Thiell <sthiell@stanford.edu>
* CLI/Nodeset.py: fix --output-format / -O when folding (-f) by applying
the provided format to each node (ticket #277).
2015-11-10 S. Thiell <sthiell@stanford.edu>
* Version 1.7 released.
2015-11-01 S. Thiell <sthiell@stanford.edu>
* Clush.py: added -P/--progress to force display of the live progress
indicator and display global write bandwidth when writing standard input.
2015-10-25 S. Thiell <sthiell@stanford.edu>
* Clush.py: added --option/-O clush.conf settings override (pull
request #248).
2015-10-18 S. Thiell <sthiell@stanford.edu>
* Clush.py: added --hostfile command line option to specify a file
containing single hosts, node sets or node groups (ticket #235).
2015-10-16 S. Thiell <sthiell@stanford.edu>
* NodeSet.py: enhancing parser to recognize nodesets with brackets having
leading/trailing digits like in "prod-00[01-99]" (ticket #228).
2015-08-29 S. Thiell <sthiell@stanford.edu>
* CLI/Nodeset.py: added --axis option to choose nD fold axis (ticket
#269).
* NodeSet.py: added fold_axis public member to NodeSetBase along with
expand algorithm when casting to string to choose nD fold axis (ticket
#269).
2015-08-28 S. Thiell <sthiell@stanford.edu>
* CLI/Config.py: better per-user clush.conf support. clush now also checks
for $XDG_CONFIG_HOME/clustershell/clush.conf and
$HOME/.local/etc/clustershell/clush.conf (ticket #111).
2015-08-27 S. Thiell <sthiell@stanford.edu>
* CLI/Nodeset.py: add --list-all / -L to list groups from all group
sources (ticket #266). If repeated, it has the same behavior than -l.
* NodeUtils.py: add support for built-in groups definition files based on
YAML. Added autodir configuration option in groups.conf to declare a
directory where .yaml files are automatically loaded. Example available in
groups.d/cluster.yaml.example. Added support for groups.conf section with
multiple source names separated by comma. This is also the case for
groups.conf.d/*.conf extensions. Also added new upcall command $SOURCE
variable that is replaced by calling source name before execution.
Finally, /etc/clustershell/groups is now deprecated and replaced by
/etc/clustershell/groups.d/local.cfg for new installation (ticket #258).
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
list belonging groups (a new 1.6 feature, see ticket #162).
2012-03-29 S. Thiell <stephane.thiell@cea.fr>
* Worker/Worker.py: added documentation for
worker.current_[node,msg,errmsg,rc] variables (ticket #160).
* Task.py: timeout parameters better explained (ticket #157).
2012-03-28 S. Thiell <stephane.thiell@cea.fr>
* CLI/OptionParser.py: Add --diff option to enable diff display between
gathered outputs. Enabled in clush and clubak (ticket #176).
* CLI/Display.py: Add _print_diff() and flush() methods.
* Task.py: Initialize MsgTree instances in constructor according to
default values in order to allow no-op calls to buffer getters before
resume() (ticket #186).
2012-03-26 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Fix clush --[r]copy behavior when no source directory is
specified (ticket #172).
* CLI/Clush.py: Fix interactive mode gather/standard toggle error, when
using special character '=' (ticket #171).
* CLI/Clubak.py: Add -v/-q verbosity options (ticket #174).
2012-03-24 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clubak.py: Add --interpret-keys=never,always,auto option to clubak
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).
* Packaging: Add groups.conf.d directory and sample files.
2012-03-17 S. Thiell <stephane.thiell@cea.fr>
* CLI/Nodeset.py: Add support for -l[ll] <nodeset(s)> to list belonging
groups (CLI interface to NodeSet.groups()) (ticket #162).
* NodeSet: Add groups() public method to list groups nodeset belongs to.
2012-03-15 S. Thiell <stephane.thiell@cea.fr>
* NodeUtils.py: Add groupsdir option (ticket #179).
2012-03-14 S. Thiell <stephane.thiell@cea.fr>
* CLI/Nodeset.py: Add --contiguous splitting option (ticket #173).
* NodeSet.py: Add contiguous() iterator.
* RangeSet.py: Add contiguous() iterator.
* RangeSet.py: Allow slice object in fromone() constructor.
2012-02-26 S. Thiell <stephane.thiell@cea.fr>
* Gateway.py: Improved logging facility, configurable through
CLUSTERSHELL_GW_LOG_DIR and CLUSTERSHELL_GW_LOG_LEVEL environment
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.
* Worker/Tree.py: Integrate WorkerTree within ClusterShell Engine
framework, it will be used instead of PropagationTree.
* Engine/Engine.py: Inhibit any engine client changes when client is not
registered.
* Topology.py: Change DEFAULT section to Main section in topology.conf.
Cosmetic changes.
2011-06-09 S. Thiell <stephane.thiell@cea.fr>
* Version 1.5.1 released.
* NodeSet.py: Added workaround to allow pickling/unpickling of RangeSet
objects for Python 2.4 (ticket #156).
2011-06-08 S. Thiell <stephane.thiell@cea.fr>
* Version 1.5 released (Sedona release).
2011-06-07 S. Thiell <stephane.thiell@cea.fr>
* MsgTree.py: Improved MsgTree API to lighten updates of keys associated
to tree elements (ticket #131).
* CLI/Clubak.py: Updated for new MsgTree API and added a -F/--fast switch
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).
2011-05-29 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Fixed missing autostep check in _fold() which could lead to
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>
* Worker/EngineClient.py: Enable fastsubprocess module, and use file
descriptors instead of file objects everywhere (ticket #153).
* Worker/fastsubprocess.py: Faster, relaxed version of Python 2.6
subprocess.py with non blocking fd support.
2011-05-15 S. Thiell <stephane.thiell@cea.fr>
* Engine/Engine.py: Improved start_all() fanout algorithm by adding a
separate pending clients list.
* Created 1.5 branch.
2011-03-19 S. Thiell <stephane.thiell@cea.fr>
* Version 1.4.3 released.
* CLI/Nodeset.py: Make stdin '-' keyword work when used for -i/x/X
operations (ticket #148).
* CLI/Clush.py: Fixed issue when using clush -bL (missing argument) due to
latest 1.4.2 changes. Added tests/ClushScriptTest.py to detect that in
the future (ticket #147).
2011-02-15 S. Thiell <stephane.thiell@cea.fr>
* Version 1.4.2 released.
2011-03-12 S. Thiell <stephane.thiell@cea.fr>
* NodeSet.py: Fixed issues with objects copying, so got rid of copy module
and added optimized RangeSet.copy() and NodeSet.copy() methods (ticket
#146).
2011-03-09 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Added running progress indicator for --[r]copy commands.
2011-03-08 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Improved -v switch (closes ticket #100: print live node
output plus noderange-grouped output at the end).
* CLI/Clubak.py: Add -T,--tree message tree mode option (ticket #144).
* MsgTree.py: Class initialization variant (trace mode) to keep track of
old keys/nodes for each message (part of #144).
2011-03-06 S. Thiell <stephane.thiell@cea.fr>
* CLI/Clush.py: Implement clush -L (not -bL) to order output by nodename,
like clubak -L (ticket #141).
* CLI/Nodeset.py: Added -I/--slice command option to select node(s) by
index(es) or RangeSet-style slice (ticket #140).
* CLI/Nodeset.py: Remove pending limitation when using -[ixX] operations
with nodesets specified by -a (all) or through stdin.
* NodeSet.py: Add RangeSet.slices() method.
