Merged latest release changes back into the trunk
1 This file contains release notes and a change history for the
2 lrms python module.
3
4 Release 2.2.0 : first release of this package as a separate RPM. Both lcg-info-dynamic-scheduler
5 and lcg-info-dynamic-scheduler-pbs depend on this python module, makes sense to have it as a
6 separate RPM. Otherwise this is identical to the lrms.py module shipped with the
7 lcg-info-dynamic-scheduler-generic package since version 2.1.0.
8
9 Below refer to versions of lrms.py that were release with the lcg-info-dynamic-scheduler-generic pacakge.
10 This was before the restructuring of the RPMs. Hence the version numbers refer to lcg-info-dynamic-scheduler-generic.
11
12 Release 2.1.0
13
14 lrms.py was changed in order to support caching of search results.
15 Most of the time spent in lcg-info-dynamic-scheduler was due to
16 queries like "find all jobs from group 'lhcb', in state 'waiting',
17 for queue 'qlong'. Queries like this are now cached for future use,
18 and can also be supplied *before* use, like they now are for
19 lcg-info-dynamic-scheduler. That program now generates slices
20 of the job list for the various combinations queue/group/state
21 that will be needed while running the program.
22
23 There were previously two different 'return a list of matching job'
24 functions, with different interfaces. These now have a unified
25 interface so that result caching can be supported. This does break
26 backwards compatibility for lrms.py.
