merge: mark .hgsubstate as possibly dirty before submerge for consistency Before this patch, failure of updating subrepos may cause inconsistent ".hgsubstate". For example: 1. dirstate entry for ".hgsubstate" of the parent repo is filled with valid size/date (via "hg state" or so) 2. "hg update" is invoked at the parent repo 3. ".hgsubstate" of the parent repo is updated on the filesystem as a part of "g"(et) action in "merge.applyupdates" 4. it is assumed that size/date of ".hgsubstate" on the filesystem aren't changed from ones at (1) this is not so difficult condition, because just changing hash ids (every ids are same in length) in ".hgsubstate" doesn't change the file size of it 5. "subrepo.submerge()" is invoked to update subrepos 6. failure of updating in one of subrepos raises exception (e.g. "untracked file differs") 7. "hg update" is aborted without updating dirstate of the parent repo dirstate entry for ".hgsubstate" still holds size/date at (1) Then, ".hgsubstate" of the parent repo is treated as "CLEAN" unexpectedly, because updating ".hgsubstate" at (3) doesn't change size/date of it on the filesystem: see assumption at (4). This inconsistent ".hgsubstate" status causes unexpected behavior, for example: - "hg revert" forgets to revert ".hgsubstate" - "hg update" misunderstands that (not yet updated) subrepos diverge (then, it shows the prompt to confirm user's decision) To avoid inconsistent ".hgsubstate" status above, this patch marks ".hgsubstate" as possibly dirty before "submerge" invocation. "normallookup"-ed (= dirty) dirstate should be written out, even if processing is aborted by failure. This patch marks ".hgsubstate" as possibly dirty before "submerge", also when it is removed or merged while merging, for safety. This should prevent Mercurial from misunderstanding inconsistent ".hgsubstate" as clean. To satisfy conditions at (1) and (4) above, this patch uses "hg status --config debug.dirstate.delaywrite=2" (to fill valid size/date into dirstate) and "touch" (to fix date of the file).

rebase: ensure rebase revision remains visible (issue4504) Before this changeset rebase was getting very confused if any revision in the rebase set became hidden. This was fairly easy to achieve if a rebased revision was made visible by the working copy location. The rebase process would update somewhere else and the revision would become hidden. To work around this issue, we ensure rebased revisions remain visible for the whole process. This is a simple change suitable for stable. More subtle usage of unfiltered repository in rebase may solve this issue more cleanly.

extdiff: reintroduce backward compatibility with manual quoting of parameters 72a89cf86fcd broke things ... and the following cleanups didn't fix all issues. It didn't work with the diffargs shipped in mergetools.rc with explicit quoting. Parameters would end up with being quoted twice - especially if they really needed quoting. To work around that, look for explicit quotes around the variables that will be substituted with proper quoting. Also accept an additional prefix so we can handle both --foo='$parent' and '--foo=$parent' It will however still fail if the user intentionally place the variable inside a quoted string, as in 'parent $parent is on the left' There is currently no good way to handle that, short of knowing exactly which quoting mechanism will be used.

mergetools: drop incorrect quoting of diffargs variables 72a89cf86fcd introduced automatic quoting of diffargs in a not entirely backwards compatible way. That rendered some of the configuration in mergetools.rc invalid. It would fail when running extdiff on a single file with a name that needed quoting. Before: $ hg config merge-tools.meld.diffargs -a --label='$plabel1' $parent --label='$clabel' $child $ hg --config extdiff.meld= -v --debug meld running "/usr/bin/meld -a --label=''sp ace@0'' '.../Z.b7a65a1d2f84/sp ace' --label=''sp ace'' '.../sp ace'" in ... meld: error: too many arguments (wanted 0-3, got 4) After: $ hg config merge-tools.meld.diffargs -a --label=$plabel1 $parent --label=$clabel $child $ hg --config extdiff.meld= -v --debug meld running "/usr/bin/meld -a --label='sp ace@0' '.../Z.b7a65a1d2f84/sp ace' --label='sp ace' '.../sp ace'" in ... (success)

namespace: introduce logfmt to show l10n-ed messages for hg log correctly Before this patch, "_()" is used incorrectly for "tag:" and "bookmark:" fields. "changeset_printer()" looks up keys composed at runtime, and it prevents "xgettext" command from getting strings to be translated from source files. Then, *.po files merged with updated "hg.pot" lose msgids for "tag:" and "bookmark:". This patch introduces "logfmt" information into "namespace" to show l10n-ed messages "hg log" (or "changeset_printer()") correctly. For similarity to other namespaces, this patch specifies "logfmt" for "branches" namespace, even though it isn't needed (branch information is handled in "changeset_printer()" specially). To find related code paths out easily, this patch adds "i18n: column positioning ..." comment to the line composing "logfmt" by default, even though this line itself doesn't contain any strings to be translated.

osutil: fix memory leak of PyBytes of path in statfiles Spotted with cpychecker.

revert: move prefetch to after the actions logic The prefetch logic came before the actual population of the actions collection, so it was always being passed an empty action list. This fixes it by moving it to after that logic. The only consumer of this function at the moment is remotefilelog, and I verified it works with this change.

largefiles: revert to lfilesrepo.status() being an unfiltered method This effectively reverts 67d63ec85eb7, which caused some normal file copies to not be displayed as copies. Other normal file copies could be displayed- the exact reason isn't clear. This also adds two tests that were failing prior to this backout, so that this can be sorted out next cycle. The difference between copy cases that worked and those that didn't seemed to be in copies.pathcopies(). When largefiles isn't enabled for the changed test, or lfstatus is not set in the commands.status() override, 'y.ancestor(x) == x'. That wasn't true otherwise, which fell through to the _chain() method. In this case, the copy is removed in the criss cross loop. 'y.ancestor(x)' returns a context.changectx type, while 'x' is a lfilesctx type in the failing case. I tried adding the ancestor method to the lfilesctx class to change the type of the ancestor context, however the context when printed as a string then gains a '+'. This points to it being a context.committablectx, which clearly isn't correct for an ancestor. Possibly the problem is the lfilesctx needs to subclass context.committablectx in some cases, but context.changectx in others, within the same invocation? I'm not sure how to pull that off, and backing out this change is safer during the freeze. As to the status changing when a path is specified, I haven't looked into it yet.

test-tools: portability tweak

revset: fix ancestors(null) to include null revision (issue4512) Since 13c0327eeb6f, null parent is explicitly excluded. So, there is no reason to have nullrev in the initial seen set.

log: use rev() to build revset of --follow option from numeric revision startrev can be -1.

revset: allow rev(-1) to indicate null revision (BC) This can simplify the conversion from numeric revision to string. Without it, we have to handle -1 specially because repo['-1'] != repo[-1]. The -1 revision is not officially documented, but this change makes sense assuming that "rev(%d)" exists for scripting or third-party tools.

extensions: don't quit loading extensions in the middle if traceback is on This was introduced way back in 2006 (rev 1f6d520557ec) as sys.exit(0) if loading an extension failed when --traceback was on, then at some point morphed into a 'return 1' in a function that otherwise returns nothing. At this point, if ui.traceback is enabled and if loading an extension fails for whatever reason, including one as innocent as it not being present, we leave any extensions loaded so far in a bogus half-initialized state. That doesn't really make any sense.

test-hgweb: fix shutdown race Logfiles weren't necessarily being flushed before being read.

tests: invoke hg command indirectly from shell script to run on Windows Before this patch, test-tag.t can't run successfully on Windows, because: - quoted hg command ('"hg"') prevents "hg.bat" from working correctly (only at testing with pure Python build) "%~f0" and "%~dp0hg" in "hg.bat" cause unexpected result in this case. BTW, quoted "\path\to\hg" works correctly. - "`pwd`" in the command line is expanded unexpectedly not "C:\path\to\TESTTMP" but "C;C:\path\to\TESTTMP"

log: evaluate filesets on working copy, not its parent When running "hg log 'set:added()'", we create two matchers: one used for producing the revset and one used for finding files to match. In 1fd352aa08fc (graphlog: evaluate FILE/-I/-X filesets on the working dir, 2012-02-26), we started passing a revision argument along from what's currently in cmdutil._makelogrevset() to revset._matchfiles(). When the revision was an empty string, it referred to the working copy. This was subtly done with "repo[rev or None]". Then, in f2aeff8a87b6 (revset: avoid recalculating filesets, 2014-10-22), that conversion from empty string to None was lost. Note that repo[''] is equivalent to repo['.'], not repo[None]. The consequence of this, to the user, is that when running "hg log 'set:added()'", the file matcher matches files added in the working copy, while the revset matcher matches revisions that touch files added in the parent of the working copy. As a result, only revisions that touch any files added in the parent of the working copy will be considered, but they will only be included if they also touch files added in the working copy. Fix the bug by converting '' to None again, but make it a little more explicit this time (plus, we now have tests for it).
