histedit: do not stay on a cleaned nodes on abort There is case where nodes are neither in tmpnodes nor leaf but still get removed. For example, if you used the "edit" action, made a commit and run --abort. The commit you made is not tracked by histedit, yet it will likely be cleaned up with its parent. The commit may not tracked because no replacements computations are done in the --abort case.

histedit: also update away from tmpnodes The working copy may be on a tmpnodes, we need to update away before it is stripped from the repository.

histedit: use revset to check if we need to update during abort The for loop is already quite more complicated than necessary and we are about to add some logic. Instead, we use a simple revset. Revset laziness should provide us with similar performance.

histedit: remove useless 'else' clause This 'else: pass' clause have no effect. We drop it for clarity.

histedit: make cleanupnode more robust The goal of this function is to strip content out of the repository. We do not really care if this content is visible or cleanup node not and we should proceed anyway. None of the internal actions are subject to this, however, a third party extension running arbitrary commands during histedit is affected by this.

convert: fix git convert using servers branches The conversion from git to hg was reading the remote branch list directly from the origin server. If the origin's branch had moved forward since the last git fetch, it would return a git hash which didn't exist locally, and therefore the branch was not converted. This changes it to rely on the local repo's refs/remotes list of branches instead, so it's completely cut off from the server.

revrange: drop old-style parser in favor of revset (API) Now revset can parse nullary ":" operator and existing "foo+bar" tags, we don't need the old-style parser. This means scmutil.revsingle(), revpair() and revrange() no longer accept a binary nodeid. An integer revision is still allowed as it isn't ambiguous.

tag: do not pass binary nullid to scmutil.revsingle() Future patches will remove the old-style parser that happen to accept a binary nodeid. A binary nodeid shouldn't be passed to scmutil.revrange() because it is ambiguous. For example, bin('20' * 19 + '30') is valid binary nodeid, but it can also be parsed as a revset expression, '0'.

revset: port parsing rule of old-style ranges from scmutil.revrange() The old-style parser will be removed soon.

debugrevspec: pass lookup function to visualize fallback mechanism The next patch will move the exceptional parsing of old-style ranges to revset.tokenize(). This patch will allow us to see the result tree. Note that the parsing result of '-a-b-c-' is incorrect at this changeset. It will be fixed soon.

help: fix typo familar -> familiar

highlight: exit early on textual and unknown files (issue3005) When highlight extension encountered files that pygments didn't recognize, it used to fall back to text lexer. Also, pygments uses TextLexer for .txt files. This lexer is noop by design. On bigger files, however, doing the noop highlighting resulted in noticeable extra CPU work and memory usage: to show a 1 MB text file, hgweb required about 0.7s more (on top of ~3.8s, Q8400) and consumed about 100 MB of RAM more (on top of ~150 MB). Let's just exit the function when it's clear that nothing will be highlighted. Due to how this pygmentize function works (it modifies the template in-place), we can just return from it and everything else will work as if highlight extension wasn't enabled.

histedit: extract a simpler function to process replacement on abort The process replacement is building a full mapping to allow moving bookmarks and creating obsolescence marker. We do not need the full logic for abort so we extract it. It will be useful as abort is missing some data about the replacement and can crash when third party extensions push it a bit too far.

exchange: fix dead assignment The assignment of the value from bundle2.processbundle() to 'r' is unused. It is currently the same as its third argument (if given), and since that argument may eventually go away (according to the method's docstring), let's reassign the return value to 'op' instead to better prepare for that.

exchange: s/phase/bookmark/ in _pushb2bookmarks()

histedit: backout ebb5bb9bc32e The faulty changeset use obsolescence marker to roll the repository back on --abort. This is a problematic approach because --abort should be as close as an actually transaction rollback as possible stripping all created data from the repository (cf `hg rebase --abort` stripping all created changesets). Instead ebb5bb9bc32e made all content created during the aborted histedit still available in the repository adding obsolescence marker to make them hidden. This will cause trouble to evolution user as a re-run of the same histedit (with success) will likely result in the very same node to be "recreated" while obsolescence marker would be in place for them. And canceling an obsoletion is still a fairly complicated process. This also rollback using obsmarkers instead of strip to clean up temporary node on successful histedit run because the two change were not split in separated changeset. Rolling that part back does not have significant consequence a will have to be resubmitted independently

convert: when converting from Perforce use original local encoding by default On Windows Perforce command line client uses default system locale to encode output. Using 'latin_1' causes locale-specific characters to be replaced with question marks. With this patch we will use default locale by default whilst allowing to specify it explicity with 'convert.p4.encoding' config option. This is a potentially breaking change for any scripts relying on output treated as in 'latin_1' encoding. Also because hgext.convert.convcmd overwrites detected default system locale with UTF-8 we had to introduce an import cycle in hgext.convert.p4 to retrieve originally detected encoding from hgext.convert.convcmd.

convert: when getting file from Perforce concatenate data at the end As it turned out, even when getting relatively small files, concatenating string data every time when new chunk is received is very inefficient. Maintaining a string list of data chunks and concatenating everything in one go at the end seems much more efficient - in my testing it made getting 40 MB file 7 times faster, whilst converting of a particularly big changelist with some big files went down from 20 hours to 3 hours.

help: scripting help topic There are a lot of non-human consumers of Mercurial. And the challenges and considerations for machines consuming Mercurial is significantly different from what humans face. I think there are enough special considerations around how machines consume Mercurial that a dedicated help topic is warranted. I concede the audience for this topic is probably small compared to the general audience. However, lots of normal Mercurial users do things like create one-off shell scripts for common workflows that I think this is useful enough to be in the install (as opposed to, say, a wiki page - which most users will likely never find). This text is by no means perfect. But you have to start somewhere. I think I did cover the important parts, though.

transplant: restore dirstate correctly at unexpected failure Before this patch, transplant can't restore dirstate as expected at failure other than one while patching. This causes: - unexpected file status - dirstate refers already rollback-ed parent (only at failure of transplanting the 2nd or later revision) To restore dirstate correctly also at unexpected failure, this patch encloses scope of store lock and transaction by 'dirstateguard'. This is temporary fixing for stable branch. See DirstateTransactionPlan wiki page for detail about the future plan to treat dirstate consistently around scope boundary of transaction. https://mercurial.selenic.com/wiki/DirstateTransactionPlan This patch also adds 'if lock' examination for safety 'lock.release()', because creating 'dirstateguard' object may fail unexpectedly (e.g. IOError for saving dirstate). BTW, in the test script, putting section header '[extensions]' into '.hg/hgrc' is needed to fix incomplete disabling 'abort' extension at 4d1382fd96ff.
