mq: fix qapplied --last and qprev documentation (issue3282) qapplied --last is qprev not qtop. v2: - Replace "previous" with "preceding" as suggested here and there

setup: handle output from Apple's Xcode 4.3 better (issue3277) Apparently, it prints nothing at all if the user installed only the command-line tools. In that case, don't try to parse the empty output -- just assume they have Xcode >= 4.

graphlog: apply file filters --patch/--stat output When passing --patch/--stat, file filters have to be applied to generate the correct diff or stat output: - Without --follow, the static match object can be reused - With --follow, the files displayed at revision X are the ancestors of selected files at parent revision. To do this, we reproduce the ancestry calculations done by --follow, lazily. test-glog.t changes show that --patch output is not satisfying because renames are reported as copies. This can probably be fixed by: - Without --follow: compute files to display, look for renames sources and extend the matcher to include them. - With --follow: detect .path() transitions between parent/child filectx, filter them using the linked changectx .removed() field and extend fcache with them.

context: add followfirst arg to filectx and workingfilectx When _followfirst() revset was introduced it seemed to be the sole user of such an argument, so filectx.ancestors() was duplicated and modified instead. It now appears this argument could be used when computing the set of files to be considered when --patch or --stat are passed along with --follow FILE.

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.

graphlog: implement --follow-first log --graph --follow-first FILE cannot be compared with the regular version because it never worked: --follow-first is not taken in account in walkchangerevs() fast path and is explicitely bypassed in FILE case in walkchangerevs() nested iterate() function.

graphlog: implement --follow with file arguments

test-glog: test multiple --prune values

graphlog: restore FILE glob expansion on Windows On platforms not supporting shell expansion, scmutil.match() performs glob expansion on 'pats' arguments. But _matchfiles() revset calls match.match() directly, bypassing this behaviour. To avoid duplicating scmutil.match(), a secondary scmutil.matchandpats() is introduced returning both the match object and the expanded inputs. Note the expanded pats are also needed in the fast path, and will be used by --follow code path.

glog: restore multiple --rev test lost in rebasing

copies: remove checkdirs options This removes the undocumented merge.followdirs option, which has always been true.

copies: add docstring for mergecopies

addremove: return 1 if we failed to handle any explicit files

log: fix --follow FILE ancestry calculation Currently, --follow FILE looks for a FILE filelog, scans it and collects linkrevs and renames, then filters them. The problem is the filelog scan does not start at FILE filenode in parent revision but at the last filelog revision. So: - Files not in the parent revision can be followed, the starting node is unexpected - Files in the parent revision can be followed from an incorrect starting node. This patch makes log --follow FILE fail if FILE is not in parent revision, and computes ancestors of the parent revision FILE filenode.
