parsers: fix two leaks in index_ancestors Both happy paths through this function leaked the returned list: 1) If the list was of size 0 or 1, it was retained an extra time and then returned. 2) If the list was passed to find_deepest, it was never released before exiting this function. Both paths spotted by cpychecker.

reachableroots: extend "revstates" to array of bit flags

reachableroots: rename "seen" array to "revstates" for future extension It will be an array of bit flags, SEEN | ROOT | REACHABLE.

reachableroots: give anonymous name to short-lived "numheads" variable I'll reuse it for the length of the roots list.

reachableroots: reduce nesting level by jumping to next iteration by continue This can eliminate lines over 80 columns. No code change except for the outermost "if" condition.

convert: fix convert dropping p2 contents during filemap merge When converting a merge commit using a filemap convert (i.e. when moving contents from the root of the repo into subdir1/), convert would silently drop the entire contents of the target repo's p2. This was because when it built the target commit, it did so by taking the target p1 and adding only the files that changed in the source repo's merge commit. This breaks in the case where the target repo has files that are unrelated to the source repo (like in the case where you use convert to import a repo as a subdirectory of another). The fix is to use Mercurial's merge logic to detect which files in p2 we should carry over to the merge. It follows three rules: 1) if the file belongs to the source, don't try to merge it. Rely on the list of files provided to putcommit to be correct. 2) if the file requires merging or user input (change vs deleted), throw an exception. We don't have enough info to do this. 3) if p2 has the newest, non-merge-requiring version of the file, take it I've also added a test to cover this issue.

convert: implements targetfilebelongstosource for filemap source This is an implementation of the new targetfilebelongstosource() function for the filemapper. It simply checks if the given file name is prefixed by any of the rename destinations. It is not a perfect implementation since it doesn't account for the filemap specifying includes or excludes, but that makes the problem much harder, and this implementation should suffice for most cases.

convert: add function to test if file is from source This adds a base implementation of a function that tests if a given file from a target repo came from the source repo. This will be used later to detect which files did not come from the source repo during a merge, so we can merge those files correctly instead of dropping them.

revsetbenchmarks: run make after update so that C extensions are built

reachableroots: fix memleak of integer objects at includepath loop In the first visit loop, val is decref-ed correctly after PySet_Add(). Let's do the same for the includepath loop.

reachableroots: bail if integer object cannot be allocated This patch also replaces Py_XDECREF() by Py_DECREF() because we known "val" and "p" are not NULL. BTW, we can eliminate some of these allocation and error handling of int objects if the internal "seen" array has more information. For example, enum { SEEN = 1, ROOT = 2, REACHABLE = 4 }; /* ... build ROOT mask from roots argument ... */ if (seen[revnum + 1] & ROOT) { /* instead of PySet_Contains(roots, val) */ >From my quick hack, it is 2x faster.

devel-warn: issue a warning when writing bookmarks without holding the wlock I saw an issue in an extension that we develop where we were writing bookmarks without holding the wlock. Another extension was taking a lock at the same time and wiped out the bookmarks we were about to write. This patch adds a devel-warning to urge people to fix their invalid code.

rebase: lock the repo during the full rebase operation Running `hg pull --rebase` would move bookmarks without any repository locking. So we now lock the repository. For good measure and avoiding sneaky race conditions, we lock the repository for the whole operation. There is no code change besides the indentation.

update: wlock the repo for the whole 'hg update' command The update command is touching the repository and should lock it for the length of its operations. Equally importantly, it should lock the repository when it is writing bookmarks. It wasn't doing so until now, leaving doors open for all kinds of drunk beaver parties. This results in some minor tests changes, and the fixing of a couple of bugs from race conditions. Code does not receive any changes beside extra indentation.

help: fix typo in scripting documentation

hg: avoid auto sharing when the clone destination is remote Before this patch, when auto sharing is enabled, 'hg.clone()' tries to create local clone regardless of locality of the clone destination on the host, and causes failure. To avoid auto sharing when the clone destination is remote, this patch adds examination of 'islocal(dest)' before auto sharing in 'hg.clone()'. 'islocal(dest)' is examined after 'sharepool', because: - the former is more expensive than the latter - without enabling share extension, the later is always negative

largefiles: ensure lfutil.getstandinmatcher() only matches standins Previously, simply having the largefiles extension loaded without any largefiles added would crash when amending with -I. The problem was with no files in the matcher, the pattern list of files joined with 'standindir' was empty, and scmutil.match() would match everything. In lfutil.composestandinmatcher(), the match function is used to test if the file is a standin, and after getting a false positive, proceeds to call lfutil.splitstandin(). This returns None because it isn't a standin, which blows up when passed to rmatcher.matchfn(). Manually overriding _always in getstandinmatcher() probably isn't necessary anymore, but we leave well enough alone on stable. This regressed in ab618e52788a.

dirstate: add --minimal flag to debugrebuilddirstate On repositories with hundreds of thousands of files, hg debugrebuilddirstate causes every dirstate entry to be marked lookup, and the next hg status can take many minutes. This adds a --minimal flag that allows us to only rebuild the parts of the dirstate that are inconsistent. This follows two rules: 1) If a file is in the dirstate but not in the parent manifest, and it is not marked 'add', it is busted and we should drop it. 2) If a file is not in the dirstate at all, but it is in the parent manifest, it should be added to the dirstate and we need to mark it as lookup. This allows us to fix repositories where the dirstate doesn't match the manifest much more quickly. Tested by artificially adding bad dirstate entries (via code) for both cases above.

tests: make filterpyflakes.py read target files relatively to cwd Before this patch, 'filterpyflakes.py' reads target files relatively to own location. But this prevents third party tools from using it in own source tree, because their files are placed separately from 'filterpyflakes.py'. In fact, 'test-check-pyflakes.t', which is the only user of 'filterpyflakes.py', changes current working directory (cwd) to the root of "test target" source tree before using it. Therefore, composing the root of source tree in 'filterpyflakes.py' is redundant. This patch makes 'filterpyflakes.py' read target files relatively to cwd by invoking 'open()' without any path composition. This also removes importing 'os' module, because there is no user of it after this patch. This is a one of preparation of issue4677.

monoblue: remove duplicate font-family property from td.source

monoblue: remove unused elements and related css Since 91b0ada2d94b and c9b88695d894, when monoblue was introduced, the code this patch removes was untouched. Presumably, there supposed to be nice graphics in the screen corners, but there never were due to: - the css being commented out - ids of the elements and of the css selectors being different - and the png files absent The "corner" elements were unstyled and didn't affect the rest of the page, so I think it's safe to remove all this.

revpair: restrict odd-range handling to top-level x:y expression (issue4774) The odd-range hack was introduced by 2a0efa1112ac for backward compatibility, but it was too widely applied. I've checked cmdutil.revpair() at 1.6, and found that ".:", ":0" and ":" are also handled as pairs. So let's enable the hack only for "x:y", "x:", "y:" and ":". test-revset.t is updated because "tip^::tip^ or tip^" shouldn't be taken as an odd range. This patch adds "tip^:tip^" instead. This patch is written for the default branch because parse() of the stable branch lacks compatibility hack for "foo+bar" tag. If we want to mitigate the issue in stable, we can add something like "and '::' in revs[0]".

revpair: update test to make a difference if odd range not handled specially It was added at 2a0efa1112ac, but there was no difference between -r2 and -r2:2 because the working directory was clean.
