revset: use phasecache.getrevset...

revset: use phasecache.getrevset This is part of a refactoring that moves some phase query optimization from revset.py to phases.py. See the previous patch for motivation. This patch changes revset code to use phasecache.getrevset so it no longer accesses the private field: _phasecache._phasesets directly. For performance impact, this patch was tested using the following query, on my hg-committed repo: for i in 'public()' 'not public()' 'draft()' 'not draft()'; do echo $i; hg perfrevset "$i"; hg perfrevset "$i" --hidden; done For the CPython implementation, most operations are unchanged (within +/- 1%), while "not public()" and "draft()" is noticeably faster on an unfiltered repo. It may be because the new code avoids a set copy if filteredrevs is empty. revset | public() | not public() | draft() | not draft() hidden | yes | no | yes | no | yes | no | yes | no ------------------------------------------------------------------ before | 19006 | 17352 | 239 | 286 | 180 | 228 | 7690 | 5745 after | 19137 | 17231 | 240 | 207 | 182 | 150 | 7687 | 5658 delta | | -38% | | -52% | (timed in microseconds) For the pure Python implementation, some operations are faster while "not draft()" is noticeably slower: revset | public() | not public() | draft() | not draft() hidden | yes | no | yes | no | yes | no | yes | no ------------------------------------------------------------------------ before | 18852 | 17183 | 17758 | 15921 | 17505 | 15973 | 41521 | 39822 after | 18924 | 17380 | 17558 | 14545 | 16727 | 13593 | 48356 | 43992 delta | | -9% | -5% | -15% | +16% | +10% That may be the different performance characters of generatorset vs. filteredset. The "not draft()" query could be optimized in this case where both "public" and "secret" are passed to "getrevsets" so it won't iterate the whole repo twice.
