blackbox: use util.getuser for portability On Windows, our implementation is more robust than Python's version.

blackbox: prevent failed I/O from causing hg to abort Instead, we simply print a warning message if opening the blackbox log file fails, or if writing to it fails.

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.
