largefiles: don't query the dirstate for key None lfutil.splitstandin(f) can be None, and we query the dirstate for that without checking if it is. This will cause problems with the upcoming move to critbit- based dicts, since they only support strings as keys.

bookmarks: moving the active bookmark deactivates it After this change, moving the active bookmark somewhere other than the current changeset (i.e., with --rev) deactivates it. Previously it would remain in .hg/bookmarks.current, which seems like a bug.

bookmarks: allow (re-)activating a bookmark on the current changeset Allow a bookmark that points to the current changeset to be made the active bookmark without requiring --force. Previously, this would've aborted with: abort: bookmark 'Z' already exists (use -f to force)

applyupdates: assign variable before we try to use it (issue3855) The variable 'fd' was getting used with a value left over from a prior iteration, causing a KeyError: '.hgsubstate'.

revset: don't abort when regex to tag() matches nothing (issue3850) This makes the tag("re:...") revset consistent with branch("re:...").

rebase: fix --collapse when a file was added then removed When a series of commits first adds a file and then removes it, hg rebase --collapse prompts whether to keep the file or delete it. This is due to it reusing the branch merge code. In a noninteractive terminal it defaults to keeping the file, which results in a collapsed commit that is has a file that should be deleted. This bug resulted in developers accidentally commiting unintentional changes to our repo twice today, so it's fairly important to get fixed. This change allows rebase --collapse to tell the merge code to accept the latest version every time without prompting. Adds a test as well.

grep: use re2 if possible Since re2 is enormously faster than Python's re module, this should help performance, ceteris paribus. grep currently has other huge performance problems that mask any gain :-(

util: add flag support to compilere

bookmarks: fix test broken by 0bba1ff2ac7b The added test reflects an error in printing the origin node of the bookmark that I fixed before committing, but I forgot to update the test (whoops).

bookmarks: allow moving a bookmark forward to a descendant Allow 'hg bookmark MARK', with an existing bookmark MARK, to move the bookmark forward to the current or specified revision, if the target revision is a descendant of the revision the bookmark currently points to. Prints a status message including the revision the bookmark was formerly at: $ hg bookmark Z moving bookmark 'Z' forward from 663762316562 Test coverage is added.

hgweb: change manifest archive links to only archive the current directory When the web server shows the manifest for a single, non top directory, append the path to the directory to the archive links. This makes the web server generate archive files that only include the current directory (and its subdirectories). Note that archive links in other pages (e.g. changeset) or at the top of the manifest are unchanged. Directory archive links have an extra "/" at the end which does not impact the result of the archive operation. Keeping it there made the implementation of this feature simpler.

hgweb: teach archive how to download a specific directory or file The archive web command now takes into account the "file" request entry, if one is provided. The provided "file" is processed as a "path" corresponding to a directory or file that will be downloaded. With this change hgweb can to process requests such as: http://mercurial.selenic.com/hg/archive/tip.zip/mercurial/templates This will download all files on the mercurial/templates directory as a zip file. It is not possible to specify file patterns ('glob', 'relglob', 'path', 'relpath', 're', 'relre' nor 'set'). The server will reject those with a 403 HTTP error response. Note that this is a first step to add support for downloading directories from the web interface. A following patch will modify the archiveentry map entry on the different templates so that it adds the current folder path to the archive links.

test-archive: gracefully handle HTTPErrors on get-with-headers This avoids pritting out a traceback when a get-with-headers call causes hgweb to respond with an HTTPError code.

bash_completion: tell an editor what type of file this is

bash_completion: allow remove to complete normal files Previously, we only completed files that had already been manually deleted. That behaviour made no sense. We now complete unmodified, modified, and deleted files.

bash_completion: match more narrowly This greatly helps completion performance for most commands that deal with files. In a working dir with 150,000 files, where we want to complete the name of a modified file under a path beginning with "a", from the root of the working dir: (old) hg status -nm . 1.7 sec (new) hg status -nm "glob:a**" 0.3 Even "hg add" becomes a little faster, in spite of being the worst case (matching untracked files).

blackbox: add backup bundle paths to blackbox logs Writes the backup bundle paths to the blackbox so it's easy to see which backup bundle is associated with which command when you are debugging an issue. Example output: 2013/03/13 10:39:56 durham> strip tip 2013/03/13 10:39:59 durham> saved backup bundle to /data/users/durham/www-hg/.hg/strip-backup/e5fac262363a-backup.hg 2013/03/13 10:40:03 durham> strip tip exited 0 after 7.97 seconds

tests: fix test-profile to not depend on HGPROF environment variable The test-profile test would fail if the user had HGPROF set to another profiler in their environment. This fix makes the test independent of that environment variable. Reverts the previous attempt to fix this, which was not cross platoform.

strip: make --keep option not set all dirstate times to 0 hg strip -k was using dirstate.rebuild() which reset all the dirstate entries timestamps to 0. This meant that the next time hg status was run every file was considered to be 'unsure', which caused it to do expensive read operations on every filelog. On a repo with >150,000 files it took 70 seconds when everything was in memory. From a cold cache it took several minutes. The fix is to only reset files that have changed between the working context and the destination context. For reference, --keep means the working directory is left alone during the strip. We have users wanting to use this operation to store their work-in-progress as a commit on a branch while they go work on another branch, then come back later and be able to uncommit that work and continue working. They currently use 'git reset HARD^' to accomplish this in git.

sshpeer: store subprocess so it cleans up correctly When running 'hg pull --rebase', I was seeing this exception 100% of the time as the python process was closing down: Exception TypeError: TypeError("'NoneType' object is not callable",) in <bound method Popen.__del__ of <subprocess.Popen object at 0x937c10>> ignored By storing the subprocess on the sshpeer, the subprocess seems to clean up correctly, and I no longer see the exception. I have no idea why this actually works, but I get a 0% repro if I store the subprocess in self.subprocess, and a 100% repro if I store None in self.subprocess. Possibly related to issue 2240.

blackbox: fix exception when logging commands with format characters When running commands like 'hg export -o mypatch-%N.patch', the blackbox would throw an exception because it tried to format %N. This change prevents it from trying to format the command string.

localrepo: always write the filtered phasecache when nodes are destroyed (issue3827) When the strip command is run, it calls repo.destroyed, which in turn checks if we read _phasecache, and if we did calls filterunknown on it and flushes the changes immediately. But in some cases, nothing causes _phasecache to be read, so we miss out on this and the file remains the same on-disk. Then a call to invalidate comes, which should refresh _phasecache if it changed, but it didn't, so it keeps using the old one with the stripped revision which causes an IndexError. Test written by Yuya Nishihara.

rebase: restore active bookmark after rebase --continue When a rebase has conflicts and the user uses rebase --continue, the previously active bookmark was not being made active once again. With this change that bookmark is made active again, just as if the rebase had never been interrupted. This changes the rebasestate file format, but should handle old formats correctly. Since the file is transient, this is even less of a problem. Adds a test to verify the new behavior. I manually tested continuing rebases with and without an active bookmark, and with and without being on the bookmark being rebased.

httppeer: avoid large dumps when we don't see an hgweb repo When we don't get an hgweb protocol response, we dump the response to the user for diagnostic purposes (it might be a cgitb message, for instance). But if we try to clone a bundle, we don't want to show the entire bundle in the error message. Also, we don't want fetch the full bundle multiple times during fallback. So we only fetch 1k here.

httppeer: improve protocol check Pre-0.6c hgweb used text/plain for protocol responses. This meant that a web server could serve a static file and confuse a client into generating a nasty traceback. Now we insist that text/plain protocol responses not include a Content-Length, which older hgweb didn't generate but will typically be produced for static files.

util: add a timed function for use during development I often want to measure the cost of a function call before/after an optimization, where using top level "hg --time" timing introduces enough other noise that I can't tell if my efforts are having an effect. This decorator allows a developer to measure a function's cost with finer granularity.

largefiles: remove wrong comment on standin matcher and code for creating dirs The existence of these directories could not be relied on anyway and all dependencies on them should have been removed.

merge with stable

templatefilters: add missing import of _

largefiles: updatelfiles should use working dir standins, not standins from p1 This makes a difference when working directory is dirty, especially when merging with a revision for which we don't have largefiles.

largefiles: simplify cachelfiles - don't spend a lot of time checking hashes cachelfiles jumped through loops to handle merges and modified files ... but it did apparently no longer have a valid reason to do so. It should just always make sure that the largefiles referenced from the standins are present - no matter which actual largefile is stored in the working directory. If there is no standin then there is nothing to fetch. The old code usually verified the hash of all largefiles every time this function was invoked - for examply by 'update'. This change makes a trivial noop update 5-10 seconds faster on our repo (with the other 50% spent doing another unnecessary hashing of all largefiles).

largefiles: don't let update leave wrong largefiles in wd if fetch fails Situations where a largefile for some reason wasn't available sometimes caused wrong largefile content and state. It has mostly been seen when interrupting download of largefiles ... and when introducing programming errors. Instead we now make sure to delete the old and wrong largefile. A missing file is a well-known error condition and much more reasonable way to handle the situation.

largefiles: missing largefiles should not be committed as removed Largefiles can easily become missing - for example if it simply isn't available or the download fail. It might even be convenient to be able to work that way in some cases. But commiting missing largefiles as if they had been 'hg remove'd is plain wrong.

largefiles: don't assume that .hg/largefiles/ still exists It might not have been created and it might have been removed.
