graphlog: fix --removed "hg log --removed FILE" does not return changesets where FILE was removed, but ones where FILE was changed and possibly removed. The flag is really here to disable walkchangerevs() fast path, which cannot see file removals by scanning filelogs.

test-glog: rewrite more tests using testlog() function

match: consider filesets as "anypats" Matt suggested this on IRC, I do not think the choice is obvious, but this one makes things simpler because while filesets are turned into a list of files into the match objects, it would more be difficult to tell invalid files passed in pats from those expanded from filesets.

graphlog: evaluate FILE/-I/-X filesets on the working dir This subtlety is not documented yet but: - pats/--include/--exclude filesets are evaluated against the working directory - --rev filesets are reevaluated against every revisions

graphlog: implement --copies

test-check-code-hg: skip test if not in a working dir (issue3248).

copies: use ctx.dirs() for directory rename detection

copies: fix mergecopies doc mapping direction

log: restore cache used by --copies The {filelog -> linkrev -> copyfrom} cache was refactored and broken by: changeset: 10060:f780b1098efc user: Patrick Mezard <pmezard@gmail.com> date: Sun Dec 13 18:06:24 2009 +0100 summary: templatekw: change {file_copies} behaviour, add {file_copies_switch} With --copies, this cache is accessed for every touched file of every revision. Unfortunately it is recreated for every revision, which means filelogs are parsed again. This patch makes the cache global again for all revisions. A couple of indicative timings of "hg log --copies", before and after: hg: 44s / 5s mozilla --limit 10000: 3m51s / 2m32s mozilla: 23m46s / 12m23s I do not know any good tool to trace memory consumption of these runs for comparisons. Watching the full mozilla run in top, the process did not seem to misbehave.
