bookmarks: explicitly convert to 'node' during initialization We know the content of the file is supposed to be full hex. So we can do the translation ourselves and directly check if the node is known. As nice side effect we now have proper error handling for invalid node value. Before: ! wall 0.021580 comb 0.020000 user 0.020000 sys 0.000000 (best of 134) After: ! wall 0.009342 comb 0.010000 user 0.010000 sys 0.000000 (best of 302)

bookmarks: prefetch 'lookup' outside of the loop Skipping the attribute lookup up raise a significant speedup. Example on a repository with about 4000 bookmarks. Before: ! wall 0.026027 comb 0.020000 user 0.020000 sys 0.000000 (best of 112) After: ! wall 0.021580 comb 0.020000 user 0.020000 sys 0.000000 (best of 134) (This is also in its own changeset to clarify the perf win from another coming changesets)

perf: add a perfbookmarks command A new command dedicated to benchmark of bookmark initialization.

perfphases: add a flag to also include file access time The flag purges all phases data so we'll have to read the file from disk again.

perf: have a generic "clearstorecache" function There are multiple places where we will want to purge some store cache. So we promote the existing _clearobsstore function to a something reusable.

localrepo: move filtername to __init__ This is obviously an instance attribute, not a type attribute. The modern Python style is to use __init__ for defining these. This exposes statichttprepo as inheriting from localrepository without calling its __init__. As a result, its __init__ defines a lot of variables that methods on localrepository's methods need. But factoring the common bits into a separate class is for another day.

obsolete: move obsstore creation logic from localrepo This code has more to do with obsolete.py than localrepo.py. Let's move it there.

match: allow pats to be None match.match already interprets "!bool(patterns)" as matching everything (but includes and excludes still apply). We might as well allow None, which lets us simplify some callers a bit. I originally wrote this patch while trying to change match.match(patterns=[]) to mean to match no patterns. This patch is one step towards that goal. I'm not sure it'll be worth the effort to go all the way there, but I think this patch still makes sense on its own.

tests: add a test for installing hg with pip in a virtualenv Since we're doing so much clever junk in our setup.py, let's have a test that exercises it. Thanks to Matt Harbison for testing this on Windows and verifying that installenv/*/hg would work as a way to work around bin being called Scripts on Windows.

hghave: add check for virtualenv
