largefiles: introduce pull --lfrev option The revset will be evaluated after the changesets has been pulled, and missing largefiles from matching revisions will be pulled to the local caches. This in combination with revsets will make it possible to specify different strategies for pulling largefiles. The revset expressions used for this option might be quite complex and will probably be most useful from scripts or an alias ... but less complicated than configuring hooks.

largefiles: refactor overridepull internals

largefiles: introduce lfpull command for pulling missing largefiles

largefiles: update help Some clarifications, and some clean-up after --cache-largefiles was introduced.

largefiles: fix cat of non-largefiles from subdirectory We were calling back to the original commands.cat from inside the walk loop that handled and filtered out largefiles. That did however happen with file paths relative to repo root and the original cat would fail when it applied its own walk and match on top of that. Instead we now duplicate and modify the code from commands.cat and patch it to handle both normal and largefiles. A change in test output shows that this also makes the exit code with largefiles consistent with the normal one in the case where one of several specified files are missing. This also fixes the combination of --output and largefiles.

largefiles: don't store whole file in memory for 'cat'

mergetools: rename 'base' to 'merged' in meld This makes it clear which panel is the target of the merge operation.

mergetools: avoid losing the merged version with meld Add -o $output. When using Meld as intended (merge from left and right into the center panel), the merged version is written to the wrong file without this option ($base, a temporary file, which is ignored by Mercurial). Add meld.check=changed as a secondary safety net.

templatekw: add default styles for hybrid types (issue3887) This allows elements like file_copies to be printed as 'name (source)' when used with join.

largefiles: improve repo wrapping detection Before this patch, repo wrapping detection in "reposetup()" of largefiles can detect only limited repo wrapping: replacing target functions by another one named as "wrap". So, it can't detect repo wrapping even in recommended style: replacing "__class__" of repo by derived class. This patch can detect repo wrapping in both styles below: - replacing "__class__" of repo by derived class (recommended style): class derived(repo.__class__): def push(self, *args, **kwargs): return super(derived, self).push(*args, **kwargs) repo.__class__ = derived - replacing function of repo by another one (not recommended style): orgpush = repo.push def push(*args, **kwargs): return orgpush(*args, **kwargs) repo.push = push

hgweb: respond HTTP_NOT_FOUND when an archive request does not match any files

archive: raise error.Abort if the file pattern matches no files Note that we could raise this exception even if no pattern were specified, but the revision contained no files. However this should not happen in practice since in that case commands.py/archive would exit earlier with an "no working directory: please specify a revision" error message instead.

ui: add 'force' parameter to traceback() to override the current print setting This will allow a current traceback.print_exc() call in dispatch to be replaced with ui.traceback() even if --traceback was not given on the command line.

ui: add support for fully printing chained exception stacks in ui.traceback() Currently, only SubrepoAbort has a cause chained to it.

subrepo: chain the original exception to SubrepoAbort The tracebacks in subrepos are truncated at the point where the original exception is caught and SubrepoAbort is raised in its place since 9e3910db4e78. That hides the most relevant subrepo methods when an error occurs. Python 2.x doesn't support chaining exceptions, so it is manually done here for manual printing later.

debugrebuildstate: rename to debugrebuilddirstate There is a lot of state, but this command is for rebuilding the dirstate.

debugstate: rename to debugdirstate There is a lot of state, but this command is for debugging the dirstate.

debugrebuildstate: clarify that rev can't be specified without -r -r has a default value of '' in the command line. The function default value of 'tip' is thus never used and any attempt at specifying revisions without -r will fail. It seems like then intended behavior was that 'hg debugrebuildstate' without any parameters should set the parents to tip. That would be very confusing now when the command primarily is used to recover from incorrect stat info. It is apparently undocumented that '' is the same as '.' ... unless it is passed in a place where revsets are used.

check-code: check txt files for trailing whitespace

check-code: catch trailing space in comments

spelling: fix typos and spelling errors

wireproto: clarify cryptic 'remote: unsynced changes' error message on push The message was not very much to the point and did not in any way help an ordinary user. 'repository changed while preparing/uploading bundle - please try again' is more correct, gives the user some understanding of what is going on, and tells how to 'recover' from the situation. The 'bundle' aspect could be seen as an implementation detail that shouldn't be mentioned, but I think it helps giving an exact error message. The message could still leave the user wondering why Mercurial doesn't lock the repo and how unsafe it thus is. Explaining that is however too much detail.

export: export working directory parent by default A common usecase for export is to preview the patch that will be patchbombed or to see what changed in a revision found by bisect. Showing the working directory parent is thus a useful and obvious default.

commit: allow closing "non-head" changesets Backout acd61dc44a39. The changeset prevented closing non-head changesets but did not provide any rationale or test case and I don't see what value it adds. Users might have their reasons to commit something anywhere - and close it immediately. And contrary to the comment that is removed: The topo heads set is _not_ included in the branch heads set of the current branch. It do not include closed topological heads. The change thus prevented closing commits on top of closing commits. A valid usecase for that is to merge closed heads to reduce the number of topological heads. The only existing test coverage for this is the failing double close in test-revset.t. It was added in 3cc2e34d7a7d and seems to not be intentional.

record: ignore trailing content when parsing patches - introduce 'other' lines This makes record work more like import which ignores for instance mail footers in a patch file. This also makes it possible for TortoiseHg to preview unapplied patches containing such footers.

record: abort on malformed patches instead of crashing

localrepo: use "vfs.rename()" instead of "util.rename()" This patch makes "_journalfiles()" return a list of pairs of journal file and corresponded vfs instance instead of a list of journal files in full path, to use "vfs.rename()" instead of "util.rename()" in "aftertrans()". "undofiles()" still returns a list of undo files in full path, because "repair.strip()" expects such list. It'll be also made to return a list of pairs of undo file and corresponded vfs at vfs migration for "repair.strip()" in the near future.

localrepo: use "vfs.setflags()" instead of "util.setflags()"

localrepo: use "vfs.readlink()" instead of "os.readlink()"

localrepo: use "vfs.islink()" instead of "os.path.islink()"
