54 The PlanetLab Node Manager manages all aspects of PlanetLab node and
55 slice management once the node has been initialized and configured by
56 the Boot Manager. It periodically contacts its management authority
57 for configuration updates. It provides an XML-RPC API for performing
58 local operations on slices.
59 nodemanager-lib only provides a skeleton and needs as a companion
60 either nodemanager-vs or nodemanager-lxc

226 - 2.1-8 is less broken than 2.1-7 for omf-friendly slices, in that the slivers would get created, but the OMF-feature probably won't work as .ssh won't get exposed to the sliver
228 * Thu Aug 30 2012 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - nodemanager-2.1-8

249 - renamed bwlimit as bwlimitlxc to avoid conflicts with util-vserver-pl
250 - purpose being to be able to run this branch on vserver nodes as well
252 * Thu Jun 21 2012 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - nodemanager-2.1-2
253 - merged nodemanager-2.0-37 in 2.1/lxc_devel and add initscript support to lxc

360 - curlwrapper has a debug mode
362 * Wed Jun 23 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-2.0-11
363 - pretty-printing/normalized python code - hopefully neutral
365 * Tue Jun 22 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-2.0-10
366 - (1) unconditionnally install and chkconfig-like a generic 'vinit' service
367 - that triggers /etc/init.d/vinit.slice if present and executable
368 - (2) install the slice-provided initscript (as per the initscript tag) as
369 - /etc/init.d/vinit.slice
370 - (3) as a result the initscript are now triggered by rc as part of the
371 - standard vserver .. start, properly attached to the vserver,
372 - and properly killed upon vserver .. stop
373 - (4) this works best with util-vserver-pl 0.3-31 or 0.4-12
375 * Wed Jun 16 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-2.0-9

377 - basic/partial support from reservable nodes through the 'reservation plugin' (not fully working yet)
378 - plugins can set 'persistent_data' to receive the latests know GetSlivers in case the connection is down
379 - cleanup: moved runtime files in /var/lib/nodemanager, and logs as /var/log/nodemanager* (see specfile)
380 - cleanup: some modules renamed (e.g. nm.py becomes nodemanager.py)
381 - cleanup: nodemanger now is a class; however plugins are still dumb modules
382 - cleanup: does not depend on obsolete Set
384 * Fri May 14 2010 Talip Baris Metin <Talip-Baris.Metin@sophia.inria.fr> - NodeManager-2.0-8

390 - Added log message to code that records the slice id
392 * Mon Apr 26 2010 Sapan Bhatia <sapanb@cs.princeton.edu> - NodeManager-2.0-6
393 - This version changes the location of the slice id for components such as PlanetFlow to look up. Previously this piece
394 - of information was stored in the 'vserver name' field of the per-vserver context structure in the kernel but we needed
395 - to move it elsewhere since Daniel decided to use that for something else (the vserver name... pedantic!).
397 * Wed Apr 14 2010 Talip Baris Metin <Talip-Baris.Metin@sophia.inria.fr> - NodeManager-2.0-5
398 - fix log_call in plugins/drl.py

409 * Thu Feb 11 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-2.0-2
410 - modules and plugins have a priority
411 - specialaccounts appears soon in the priority chain
412 - logger.log_call logs process output, and has a timeout
413 - vuser{add,del} run through bash -x
414 - nm initscript has support for 'service nm restartverbose'

418 * Fri Jan 29 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-2.0-1
419 - first working version of 5.0:
420 - pld.c/, db-config.d/ and nodeconfig/ scripts should now sit in the module they belong to
421 - nodefamily is 3-fold with pldistro-fcdistro-arch
422 - relies on GetSlivers to expose 'GetSliceFamily' for slivers
423 - (in addition to the 'vref' tag that's still exposed too)
424 - logging reviewed for more convenience
425 - support for 'service nm restartdebug'
426 - make sync knows how to publish uncommitted code on a test node

429 - emergency tag - make the setting of hmac by the sliverauth plugin more robust

432 - support for f10 and f12 in the vref slice tag
434 * Sat Jan 09 2010 Thierry Parmentelat <thierry.parmentelat@sophia.inria.fr> - NodeManager-1.8-21
436 - uses slicename 'sfacm' instead of 'genicw'
438 * Fri Oct 30 2009 Sapan Bhatia <sapanb@cs.princeton.edu> - NodeManager-1.8-20
439 - This tag is identical to 1.8-19. The main addition is PLC-controllable vsys scripts. The reason I am
440 - retagging is to eliminate any confusion associated with the -19 tag which was (temporarily) modified a few
443 * Tue Oct 27 2009 Sapan Bhatia <sapanb@cs.princeton.edu> - NodeManager-1.8-19
444 - This patch makes vsys scripts PLC-configurable. Previously, vsys scripts needed to be
445 - self-contained. With this change, they will be able to refer to the attributes associated with a
448 * Thu Oct 22 2009 Baris Metin <Talip-Baris.Metin@sophia.inria.fr> - NodeManager-1.8-18

458 * Fri Oct 09 2009 Marc Fiuczynski <mef@cs.princeton.edu> - NodeManager-1.8-15
459 - The seed for random previously was the meaning of life (i.e., 42) but
460 - that resulted in a not so random choice for the hmac. This
461 - implementation now uses a random.seed that is based on the current
464 * Tue Oct 06 2009 Marc Fiuczynski <mef@cs.princeton.edu> - NodeManager-1.8-14
465 - Minor fix such that sliverauth.py makes a more specific call to
466 - GetSliceTags that include that specific tagname it is looking for.
