i18n-ru: correct `push --new-branch` description

bundle: make bundles more portable (isue3441) This is achieved by acting as if the user had given -r<rev> for each head rev of outgoing changesets on the command line, as well as appropriate --base <rev>. The discovery information is computed as normal, and then adjusted as above.

revset: fix traceback for bogus revisions in id(rev) hg log -r "id(1234567)" now returns an empty list like rev() does.

Makefile: remove generated mercurial/__version__.py

mq: rename --check into --keep-changes I named it --check because it felt like qpush & co were checking *more* things to ensure local changes could not be lost. But it has been pointed on the mailing list that --check is already used by update command with a meaning almost opposite to this one. An alternative was --keep but qfold and qdelete already have such an option to preserve patch files and qfold may be a candidate for --check. - qpush/qpop/qgoto --check becomes --keep-changes. - mq.check becomes mq.keepchanges. - The short option -c is dropped as -k may conflict with existing --keep. The availabilitity of mq.keepchanges should not make this too painful. - Fix minor reST mistake in option description.

posix: workaround lack of TIOCGWINSZ on Irix (issue3449) On an Irix 6.5.24 system, TIOCGWINSZ is not available. This means that any usage of the "hg" tool that looks up the terminal size (e.g. "hg help") will fail with an AttributeError. A simple work-around is just to wrap this block in mercurial/posix.py with a try/except so that it ends up using the default 80 characters width.

phases: wrap docstrings at 70 characters

largefiles: don't attempt to clone all largefiles to non-local destinations

hgweb: fix filediff base calculation Previously, we were finding the most recent version of a file in a changeset and comparing it against its first file parent. This was wrong on three counts: - it would show a diff in revisions where there was no change to a file - it would show a diff when only the exec bit changed - it would potentially compare against a much older changeset, which could be very expensive if git-style rename detection was enabled This compares the file in the current context with that context's parent, which may result in an empty diff when looking at a file not touched by the current changeset.

branches: improve performance by removing redundant operations This refactors the branches command so it collects all the information it needs about a branch in one pass over the branch map. In particular, it fixes an issue where the command called repo.branchtags() to get branch tips, and then used repo.branchheads() to get the closed/open status. Both repo methods read the changelog to determine if the branch is closed, resulting in extra, redundant I/O. For the PyPy repo with 744 branches and 843 branch heads, this brings hg branches over NFS from: CallCount Recursive Total(ms) Inline(ms) module:lineno(function) 2427 0 0.9057 0.9057 <open> 2424 0 0.4096 0.4096 <method 'close' of 'file' objects> 2424 0 0.0476 0.0476 <method 'read' of 'file' objects> 1 0 0.0468 0.0468 mercurial.revlog:637(headrevs) +1 0 0.0000 0.0000 +<len> 2422 0 0.0443 0.0443 <method 'seek' of 'file' objects> 2962 0 0.0337 0.0337 <zlib.decompress> 2491 0 1.8008 0.0322 mercurial.changelog:182(read) +2491 0 1.6982 0.0315 +mercurial.revlog:881(revision) +2488 0 0.0269 0.0134 +mercurial.changelog:28(decodeextra) +4982 0 0.0085 0.0085 +<method 'split' of 'str' objects> +4982 0 0.0274 0.0049 +mercurial.encoding:61(tolocal) +2491 0 0.0039 0.0039 +<method 'index' of 'str' objects> 2491 0 1.6982 0.0315 mercurial.revlog:881(revision) +2413 0 0.0112 0.0112 +mercurial.revlog:305(rev) +2491 0 1.5315 0.0068 +mercurial.revlog:847(_chunkraw) +2491 0 0.0414 0.0058 +mercurial.revlog:945(_checkhash) +2491 0 0.0028 0.0028 +mercurial.revlog:349(flags) +2491 0 0.0025 0.0025 +<mercurial.mpatch.patches> 2422 0 1.5089 0.0286 mercurial.revlog:818(_loadchunk) +2422 0 0.4093 0.4093 +<method 'close' of 'file' objects> +2422 0 0.0451 0.0451 +<method 'read' of 'file' objects> +2422 0 0.0443 0.0443 +<method 'seek' of 'file' objects> +2422 0 0.9703 0.0096 +mercurial.store:374(__call__) +2422 0 0.0079 0.0069 +mercurial.revlog:810(_addchunk) 5804 0 0.0204 0.0204 mercurial.revlog:305(rev) 2426 0 0.9552 0.0177 mercurial.scmutil:218(__call__) +2426 0 0.9057 0.9057 +<open> +2426 0 0.0120 0.0083 +os.path:80(split) +2426 0 0.0061 0.0049 +mercurial.scmutil:92(__call__) Time: real 1.950 secs (user 0.560+0.000 sys 0.220+0.000) down to: CallCount Recursive Total(ms) Inline(ms) module:lineno(function) 1545 0 0.6035 0.6035 <open> 1542 0 0.2697 0.2697 <method 'close' of 'file' objects> 1 0 0.0547 0.0547 mercurial.revlog:637(headrevs) +1 0 0.0000 0.0000 +<len> 1542 0 0.0389 0.0389 <method 'read' of 'file' objects> 1540 0 0.0316 0.0316 <method 'seek' of 'file' objects> 1853 0 0.0227 0.0227 <zlib.decompress> 1557 0 1.2131 0.0226 mercurial.changelog:182(read) +1557 0 1.1398 0.0221 +mercurial.revlog:881(revision) +1555 0 0.0199 0.0094 +mercurial.changelog:28(decodeextra) +3114 0 0.0058 0.0058 +<method 'split' of 'str' objects> +3114 0 0.0196 0.0035 +mercurial.encoding:61(tolocal) +1557 0 0.0026 0.0026 +<method 'index' of 'str' objects> 1557 0 1.1398 0.0221 mercurial.revlog:881(revision) +1557 0 1.0307 0.0047 +mercurial.revlog:847(_chunkraw) +1557 0 0.0287 0.0040 +mercurial.revlog:945(_checkhash) +1557 0 0.0018 0.0018 +<mercurial.mpatch.patches> +1557 0 0.0018 0.0018 +mercurial.revlog:326(node) +1557 0 0.0417 0.0013 +mercurial.revlog:857(_chunkbase) 1540 0 1.0147 0.0210 mercurial.revlog:818(_loadchunk) +1540 0 0.2693 0.2693 +<method 'close' of 'file' objects> +1540 0 0.0360 0.0360 +<method 'read' of 'file' objects> +1540 0 0.0316 0.0316 +<method 'seek' of 'file' objects> +1540 0 0.6487 0.0070 +mercurial.store:374(__call__) +1540 0 0.0059 0.0052 +mercurial.revlog:810(_addchunk) 3192 0 0.0173 0.0173 mercurial.revlog:305(rev) 8184 0 0.0300 0.0147 <method 'decode' of 'str' objects> +5204 0 0.0149 0.0048 +encodings.utf_8:15(decode) +1 0 0.0004 0.0000 +encodings:71(search_function) 43 26 0.0147 0.0129 <__import__> Time: real 1.390 secs (user 0.450+0.000 sys 0.170+0.000)

strip: introduce -B option to remove a bookmark Add a -B option to remove a bookmark. All revisions are unreachable from a different head or a different bookmark will be removed too. This helps with topic branch workflow. You can create a topic branch and remove it if not needed anymore with hg strip -B topic/xyz.

largefiles: use wlock for lfconvert (issue3444) largefiles and lfconvert do dirty hacks with dirstate, so to avoid writing that as a side effect of the wlock release we clear dirstate first. To avoid confusing lock validation algorithms in error situations we unlock _before_ removing the target directory.

localrepo: strip now incrementally updates the branchheads cache Destroying history via strip used to invalidate the branchheads cache, causing it to be regenerated the next time it is read. This is expensive in large repos. This change converts strip to pass info to localrepo.destroyed() to enable to it to incrementally update the cache, improving the performance of strip and other operations that depend on it (e.g., rebase). This change also strengthens a bit the integrity checking of the branchheads cache when it is read, by rejecting the cache if it has nodes in it that no longer exist.

merge: respect bookmarks during merge Bookmarks will behave more like named branches when merge tries to pick a revision to merge. Bookmarks now to respect the current bookmarks. Bookmarks will not accidentally merged with unnamed heads or other bookmarks. However merge can pick heads with diverging bookmarks and pick those automatically. We end up with two cases for picking a revision to merge: (1) In case of an current bookmark, merge can pick a branch head that has a diverged bookmark (2) In case of no current bookmark, merge can pick a branch head that does not have a bookmark.

localrepo: introduce bookmarkheads Similar to branch heads we introduce the notion of bookmarkheads. Bookmarkheads are changests that are bookmarked with the given bookmark or a diverged version

bookmarks: delete divergent bookmarks on merge

check-code: ignore naked excepts with a "re-raise" comment This also promotes the naked except check from a warning to an error.

largefiles: optimize performance when updating (issue3440) Previously, when updating, cachelfiles was called blindly on all largefiles in the repository at the revision being updated to, despite the fact that a list of which largefiles needs to be updated has already been collected. This optimization constrains the cachelfiles call to only the largefiles that need to be updated. On a repository with about 80 largefiles, updating between two revisions that only change one largefile goes from approximately 6.7 seconds to 3.3 seconds.

rebase: allow collapsing branches in place (issue3111) We allow rebase plus collapse, but not collapse only? I imagine people would rebase first then collapse once they are sure the rebase is correct and it is the right time to finish it. I was reluctant to submit this patch for reasons detailed below, but it improves rebase --collapse usefulness so much it is worth the ugliness. The fix is ugly because we should be fixing the collapse code path rather than the merge. Collapsing by merging changesets repeatedly is inefficient compared to what commit --amend does: commitctx(), update, strip. The problem with the latter is, to generate the synthetic changeset, copy records are gathered with copies.pathcopies(). copies.pathcopies() is still implemented with merging in mind and discards information like file replaced by the copy of another, criss-cross copies and so forth. I believe this information should not be lost, even if we decide not to interpret it fully later, at merge time. The second issue with improving rebase --collapse is the option should not be there to begin with. Rebasing and collapsing are orthogonal and a dedicated command would probably enable a better, simpler ui. We should avoid advertizing rebase --collapse, but with this fix it becomes the best shipped solution to collapse changesets. And for the record, available techniques are: - revert + commit + strip: lose copies - mq/qfold: repeated patching() (mostly correct, fragile) - rebase: repeated merges (mostly correct, fragile) - collapse: revert + tag rewriting wizardry, lose copies - histedit: repeated patching() (mostly correct, fragile) - amend: copies.pathcopies() + commitctx() + update + strip
