localrepo: reset _phasesdirty flag after writing

import: handle git renames and --similarity (issue3187) There is no reason to discard copy sources from the set of files considered by addremove(). It was done to handle the case where a first patch would create 'a' and a second one would move 'a' to 'b'. If these patches were applied with --no-commit, 'a' would first be marked as added, then unlinked and dropped from the dirstate but still passed to addremove(). A better fix is thus to exclude removed files which ends being dropped from the dirstate instead of removed. Reported by Jason Harris <jason@jasonfharris.com>

context: make workingctx.forget() really warn about untracked files

largefiles: check whether specified patterns are related to largefiles strictly current 'lfiles_repo.status()' implementation examines whether specified patterns are related to largefiles in working directory (not to STANDIN) or not by NOT-EMPTY-NESS of below list: [f for f in match.files() if f in lfdirstate] but it can not be assumed that all in 'match.files()' are file itself exactly, because user may only specify part of path to match whole under subdirectories recursively. above examination will mis-recognize such pattern as 'not related to largefiles', and executes normal 'status()' procedure. so, 'hg status' shows '?'(unknown) status for largefiles in working directory unexpectedly. this patch examines relation of pattern to largefiles by applying 'match()' on each entries in lfdirstate and checking wheter there is no matched entry. it may increase cost of examination, because it causes of full scan of entries in lfdirstate. so this patch uses normal for-loop instead of list comprehensions, to decrease cost when matching is found.

log: remove caching of all visited revisions (issue3253) Not only does this eat all available memory for some users, it's slower.

pull: backout change to return code This bit a number of people.

convert: use splicemap entries when sorting revisions (issue1748) When sorting revisions before converting them, we have to edit the revision graph using splicemap entries. Otherwise, a spliced revision may be converted before its synthetic parents. Invalid splicemap revisions are now detected before starting the conversion.

convert: turn splicemap into a simple dictionary Parsing the splicemap as a mapfile was a pain because map does not let us override its parsing code and splicemap entries are not key/values. Besides we had no need for mapfiles extra features. Just parse the splicemap and return a dictionary.

debugrevspec: mention --verbose to print the parsed tree

largefiles: only cache largefiles in new heads This fixes a serious performance regression in largefiles introduced in Mercurial 2.1. Caching new largefiles on pull is necessary, because otherwise largefiles will be missing (and unable to be downloaded) when the user tries to merge or rebase a new head with an old one. But this is an expensive operation and should only be done for heads that are new from the pull, rather than on all heads in the repository.

mq: restore _branchtags() fast path (issue3223) Since a5917346c72e, mq saves the nodeid of the first applied patch to cache/branchheads, which breaks the optimized cache handling introduced in fbf8320f25c8. The problem is the revision being committed is appended to mqrepo.applied after the commit succeeds, which means mqrepo._branchtags() performs a regular update and write the first applied patch to the branch cache. One solution is to set a context variable _committingpatch on the mqrepo while it is committing a patch and to take it in account when deciding to fast-path mqrepo._branchtags(). Not really elegant but it works. The changes to test-mq-caches.t reverse changes introduced by a5917346c72e. The cache should not have been updated with mq records. The changes to test-keyword.t are indirectly caused by a5917346c72e. Reported and analyzed by Yuya Nishihara <yuya@tcha.org> Notes: - qpush still makes a slow path _branchtags() call when checking heads. Maybe this can be optimized. - be careful when merging this patch in default as secretcommit() was renamed newcommit() right after the end of the code freeze.

mq: ensure all mq commits are made with secretcommit() Having a common code path helps fixing things globally.
