filectx: use _descendantrev in parents() This lets us be lazy about linkrev adjustments when tracing history.

filectx: if we have a _descendantrev, use it to adjust linkrev This lets us use _adjustlinkrev lazily.

copies: use linkrev for file tracing limit This lets us lazily evaluate _adjustlinkrev.

filectx: use linkrev to sort ancestors We're going to make rev() lazily do _adjustlinkrevs, and we don't want that to happen when we're quickly tracing through file ancestry without caring about revs (as we do when finding copies). This takes us back to pre-linkrev-correction behavior, but shouldn't regress us relative to the last stable release.

_adjustlinkrev: reuse ancestors set during rename detection (issue4514) The new linkrev adjustement mechanism makes rename detection very slow, because each file rewalks the ancestor dag. To mitigate the issue in Mercurial 3.3, we introduce a simplistic way to share the ancestors computation for the linkrev validation phase. We can reuse the ancestors in that case because we do not care about sub-branching in the ancestors graph. The cached set will be use to check if the linkrev is valid in the search context. This is the vast majority of the ancestors usage during copies search since the uncached one will only be used when linkrev is invalid, which is hopefully rare.

filectx: move _adjustlinkrev to a method We are going to introduce some wider caching mechanisms during linkrev adjustment. As there is no specific reason to not be a method and some reasons to be a method, let's make it a method.

revset: raise RepoLookupError to make present() predicate continue the query Before this patch, "bookmark()", "named()" and "tag()" predicates raise "Abort", when the specified pattern doesn't match against existing ones. This prevents "present()" predicate from continuing the query, because it only catches "RepoLookupError". This patch raises "RepoLookupError" instead of "Abort", to make "present()" predicate continue the query, even if "bookmark()", "named()" or "tag()" in the sub-query of it are aborted. This patch doesn't contain raising "RepoLookupError" for "re:" pattern in "tag()", because "tag()" treats it differently from others. Actions of each predicates at failure of pattern matching can be summarized as below: predicate "literal:" "re:" ---------- ----------- ------------ bookmark abort abort named abort abort tag abort continue (*1) branch abort continue (*2) ---------- ----------- ------------ "tag()" may have to abort in the (*1) case for similarity, but this change may break backward compatibility of existing revset queries. It seems to have to be changed on "default" branch (with "BC" ?). On the other hand, (*2) seems to be reasonable, even though it breaks similarity, because "branch()" in this case doesn't check exact existence of branches, but does pick up revisions of which branch matches against the pattern. This patch also adds tests for "branch()" to clarify behavior around "present()" of similar predicates, even though this patch doesn't change "branch()".

templatekw: re-add showtags() to list tags keyword up in online help Changeset d69a7fc68ad5 removed "showtags()" definition for "tags" template keyword from "templatekw.py", because "namespaces" puts a helper function for it into template keyword map automatically. This works correctly from the point of view of templating functionality. But on the other hand, it removed "tags" template keyword from "hg help templates" unexpectedly, because online help text is built before "namespaces" puts a helper function for "tags" into template keyword map. This patch is a kind of backing d69a7fc68ad5 out, but this implements "showtags()" with newly introduced "shownames()" instead of originally used "showlist()".

largefiles: don't interfere with logging normal files The previous code was adding standin files to the matcher's file list when neither the standin file nor the original existed in the context. Somehow, this was confusing the logging code into behaving differently from when the extension wasn't loaded. It seems that this was an attempt to support naming a directory that only contains largefiles, as a test fails if the else clause is dropped entirely. Therefore, only append the "standin" if it is a directory. This was found by running the test suite with --config extensions.largefiles=. The first added test used to log an additional cset that wasn't logged normally. The only relation it had to file 'a' is that 'a' was the source of a move, but it isn't clear why having '.hglf/a' in the list causes this change: @@ -47,6 +47,11 @@ Make sure largefiles doesn't interfere with logging a regular file $ hg log a --config extensions.largefiles= + changeset: 3:2ca5ba701980 + user: test + date: Thu Jan 01 00:00:04 1970 +0000 + summary: d + changeset: 0:9161b9aeaf16 user: test date: Thu Jan 01 00:00:01 1970 +0000 The second added test used to complain about a file not being in the parent revision: @@ -1638,10 +1643,8 @@ Ensure that largefiles doesn't intefere with following a normal file $ hg --config extensions.largefiles= log -f d -T '{desc}' -G - @ c - | - o a - + abort: cannot follow file not in parent revision: ".hglf/d" + [255] $ hg log -f d/a -T '{desc}' -G @ c | Note that there is still something fishy with the largefiles code, because when using a glob pattern like this: $ hg log 'glob:sub/*' the pattern list would contain '.hglf/glob:sub/*'. None of the tests show this (this test lives in test-largefiles.t at 1349), it was just something that I noticed when the code was loaded up with print statements.

discovery: properly exclude locally known but filtered heads The conditional was a bit too narrow and produced buggy result when a node was present in both common and heads (because it pleased the discovery) and it was locally known but filtered. This resulted in buggy getbundle request and server side crash.

test: make test-extdiff resilient to /usr/bin/echo My test machine has 'echo' in '/usb/bin/echo', #dontaskmewhy.

obsstore: make the invalid markers check wrap-able Some evolve user ignored the invalid markers for about two years and still have some of them in some repository. This lead to plain abort whenever mercurial try to open such repo. We need reinstall some way to clean this up in the evolve extension. For this purpose, we need the checker code wrap-able independently. This is scheduled for stable as this issue is blocking some evolve user.

convert: replace revision references in messages if they are >= short hashes Convert will try to find references to revisions in commit messages and replace them with references to the converted revision. It will take any string that looks like a hash (and thus also decimal numbers) and look it up in the source repo. If it finds anything, it will use that in the commit message instead. It would do that for all hex digit sequences of 6 to 40 characters. That was usually no problem for small repos where it was unlikely that there would be a matching 6 'digit' hash prefix. It was also no problem on repos with less than 100000 changesets where numbers with 6 or more digits not would match any revision number. With more than 100000 revisions random numbers in commit messages would be replaced with a "random" hash. For example, 'handle 100000 requests' would be changed to to 'handle 9117c6 requests'. Convert could thus not really be used on real repositories with more than 100000 changesets. The default hash length shown by Mercurial is 12 'digits'. It is unexpected and unwanted that convert by default tries to replace revision references that use less than that amount of 'digits'. To fix this, don't match strings that are less than the default hash size of 12 characters.

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.

diffhelpers: fix botched return statement from c8e7fa41bfc5 Spotted by Sean Farley using clang.

subrepo: don't abort in add when non-hg subrepos are present (issue4513) This change should have been part of 9994f45ba714.

osutil: fix leak of stat in makestat when Py_BuildValue fails Spotted with cpychecker.

osutil.c: clean up space before a tab

dirs: fix leak of iterator in dirs_fromiter Spotted with cpychecker.

diffhelpers: verify hline was created before using it Found with cpychecker.

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.
