graphlog: pass changesets to revset.match() in changelog order Running: $ time hg debugrevspec 'user(mpm)' | wc on Mercurial repository takes 1.0s with a regular version and 1.8s if commands.debugrevspec() is patched to pass revisions to revset.match() from tip to 0. Depending on what we expect from the revset API and caller wisdom, we might want to push this change in revset.match() later.

graphlog: refactor revset() to return revisions When --follow and --rev are passed, --follow actual behaviour depends on the input revision sequence defined by --rev. If --rev is not passed, the default revision sequence depends on the presence of --follow. It means the revision sequence generation is part of log logic and must be wrapped. The issue described above is fixed in following patches.

store: speed up read and write of large fncache files In my tests of an fncache containing 300,000 entries, this improves read time from 567ms to 307, and write time from 1328ms to 533. These numbers aren't so great, since the fncache file is only 17MB in size, but they're an improvement.
