bookmarks: cache reverse mapping (issue5868)...
bookmarks: cache reverse mapping (issue5868) I chose a simpler implementation. If the initial cost of building reverse mapping is significant, we'll have to move it under @propertycache. The nodemap could be a dict of sets, but I think keeping a sorted list is better since each node is likely to have zero/one bookmark. Micro-benchmark with 1001 bookmarks and 1001 revisions: $ for n in `seq 0 1000`; do touch $n; hg book book$n; hg ci -qAm$n; done $ hg bookmarks --time > /dev/null (orig) time: real 0.040 secs (user 0.050+0.000 sys 0.000+0.000) (new) time: real 0.040 secs (user 0.040+0.000 sys 0.010+0.000) $ hg log -T '{bookmarks}\n' --time > /dev/null (orig) time: real 0.160 secs (user 0.160+0.000 sys 0.000+0.000) (new) time: real 0.090 secs (user 0.100+0.000 sys 0.000+0.000)

#testcases lfsremote-on lfsremote-off
#require serve no-reposimplestore
This test splits `hg serve` with and without using the extension into separate
tests cases. The tests are broken down as follows, where "LFS"/"No-LFS"
indicates whether or not there are commits that use an LFS file, and "D"/"E"
indicates whether or not the extension is loaded. The "X" cases are not tested
individually, because the lfs requirement causes the process to bail early if
the extension is disabled.

$ hg init server
$ SERVER_REQUIRES="$TESTTMP/server/.hg/requires"
Skip the experimental.changegroup3=True config. Failure to agree on this comes
first, and causes a "ValueError: no common changegroup version" or "abort:
HTTP Error 500: Internal Server Error", if the extension is only loaded on one
side. If that *is* enabled, the subsequent failure is "abort: missing processor
for flag '0x2000'!" if the extension is only loaded on one side (possibly also
masked by the Internal Server Error message).

to launch if there's lfs content and the extension is disabled.
