dirstate: preserve path components case on renames (issue3402) The original issue was something like: $ hg init repo $ cd repo $ mkdir D $ echo a > D/a $ hg ci -Am adda adding D/a $ mv D temp $ mv temp d $ echo b > d/b $ hg add d/b adding D/b $ hg ci -m addb $ hg mv d/b d/c moving D/b to d/c $ hg st A d/c R D/b Here we expected: A D/c R D/b the logic being we try to preserve case of path components already known in the dirstate. This is fixed by the current patch. Note the following stories are not still not supported: Changing directory case $ hg mv D d moving D/a to D/D/a moving D/b to D/D/b $ hg st A D/D/a A D/D/b R D/a R D/b or: $ hg mv D/* d D/a: not overwriting - file exists D/b: not overwriting - file exists And if they were, there are probably similar issues with diffing/patching.

commit: abort on merge with missing files Here is a script illustrating the previous behaviour: The merge brings a new file 'b' from remote $ hg merge 1 --debug searching for copies back to rev 1 unmatched files in other: b resolving manifests overwrite: False, partial: False ancestor: 07f494440405, local: 540395c44225+, remote: 102a90ea7b4a b: remote created -> g updating: b 1/1 files (100.00%) getting b 1 files updated, 0 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) Delete but do not remove b $ rm b $ hg st ! b The commit succeeds $ hg commit -m merge $ hg parents --template "{rev} {desc|firstline} files: {files}\n" 3 merge files: $ hg st ! b b changes were ignored, but even b existence was ignored $ hg manifest a This happens because localrepo.commitctx() checks the input ctx.files(), which is empty for workingctx.files() only returns added, modified or removed entries, and bypass files/manifest updates completely. So the committed revision manifest is the same as its first parent one, not containing the 'b' file. This patch forces the commit to abort in presence of a merge and missing files. test-merge4.t is modified accordingly as it was introduced to check hg was not just terminating with a traceback (5e9e8b8d2629).

branchmap: server should not advertise secret changeset in branchmap (Issue3303) Discovery now use an overlay above branchmap to prune invisible "secret" changeset from branchmap. To minimise impact on the code during the code freeze, this is achieve by recomputing non-secret heads on the fly when any secret changeset exists. This is a computation heavy approach similar to the one used for visible heads. But few sever should contains secret changeset anyway. See comment in code for more robust approach. On local repo the wrapper is applied explicitly while the wire-protocol take care of wrapping branchmap call in a transparent way. This could be unified by the Peter Arrenbrecht and Sune Foldager proposal of a `peer` object. An inappropriate `(+i heads)` may still appear when pushing new changes on a repository with secret changeset. (see Issue3394 for details)

merge: check for untracked files more precisely (issue3400) This fixes the regression, but still leaves the long-standing issue that merge doesn't cope with trying to merge files and directories.

revlog: backout e5750c6716eb This regresses performance of 'hg branches', presumably because it's visiting the revlog in the wrong order. This suggests we either need to fix the branch code or add some read-behind to mitigate the effect.

wireprotocol: use visibleheads as reference while unbundling (issue 3303) The `repo` object here is *always* local. Using `repo.heads()` ensure we will reject push if any secret changeset exists. During discovery, `visibleheads` were sent to the peer. So we can only expect it to send us `visibleheads` back. If any secret changeset exists:: visibleheads != repo.heads() This fix server side part of issue 3303 when pushing over the wire.

rebase: preserve mq series order, guarded patches (issue2849) The previous code was rebasing an applied series like: patch1 +guarded patch2 patch3 +guarded patch4 patch5 +guarded into: patch2 patch4 patch1 +guarded patch3 +guarded patch5 +guarded Reported by Lars Westerhoff <lars.westerhoff@newtec.eu> Also rename mq.series_dirty into mq.seriesdirty, missed by 599a72895c0d, and without effect since mq.qimport() was setting it already.

subrepo/svn: improve error message on missing files From: abort: failed to commit svn changes to: abort: cannot commit missing svn entries

subrepo/svn: abort on commit with missing file (issue3029) Previous code was printing a traceback because it expected some error output from svn. But sometimes our definition of "changed" differs with the subversion one. For instance, subversion ignores missing files when committing. And when there are only missing files, svn commit will be a successful no-op with no output. Still, we should stick to our definition including missing files in changes as doing otherwise could cause surprising behaviour for the user.

doc: flatten description of 'matching()' predicate to be formatted well current description of 'matching()' revset predicate can't be formatted well on "hg help revset" output. each descriptions for revset predicates (or something like them) are split-ed into lines, and spaces on left side of them are stripped before minirst processing. so, bullet list can't be nested. this patch just flattens description of 'matching()' predicate to be formatted well.

revset: fix adds/modifies/removes and patterns (issue3403) The fast path was triggered if the argument was not like "type:value", with type a known pattern type. This is wrong for several reasons: - path:value is valid for the fast path - '*' is interpreted as a glob by default and is not valid for fast path Fast path detection is now done after the pattern is parsed, and the normalized path is extracted for direct comparison. All this seems a bit complicated, it is tempting to drop the fast path completely. Also, the hasfile() revset does something similar (only check .files()), without a fast path. If the fast path is really that efficient maybe it should be used there too. Note that: $ log 'modifies("set:modified()")' is different from: $ log 'modifies("*")' because of the usual merge ctx.files()/status(ctx.p1(), ctx) differences.

largefiles: notice dirty large files in a subrepo Summary and commit use dirty() to check the status of a subrepository, so this overrides dirty() in the subrepo in the same manner as status() to check the large files instead of their standins. Previously, if only a large file was changed in a subrepo, summary in the top level repo would not report the subrepo was dirty and commit -S would report nothing changed. If any type of file was changed in the top repo and only a large file in the subrepo, commit -S would not commit the changes to the subrepo.

largefiles: fix status -S reporting of subrepos (issue3231) Wrapping the status command will only invoke overridestatus() and set the lfstatus field for the top level repository. Wrapping the status function is required to set the field on child repositories. Previously, status -S would report large files in a subrepo as '?' regardless of their actual states, and was inconsistent with what status would report from within that subrepo.

i18n: use locale insensitive format for datetimes as intermediate representation (issue3398) on some non "en" locale environments, "hg convert" is aborted, because "util.parsedate()" fails. it fails in "memctx.__init__()" called by "putcommit()" of "convert". in "hg convert", datetimes gotten from source repository are usually formatted by "util.datestr()" with default format "%a %b %d %H:%M:%S %Y %1%2". but on some environments, "%a" and "%b" may cause locale sensitive string, and such string may cause parse error in "util.parsedate()". this path uses "%Y-%m-%d %H:%M:%S %1%2" as intermediate representation format for datetimes, because it consists only of locale insensitive elements. datetimes in above format are only used for passing them from conversion logic to memctx object, so it doesn't have to be formatted by locale sensitive one. this patch just avoids locale sensitivity problem of "datestr()" and "parsedate()" combintion.

convert/svn: make svn sink work with svn 1.7 "svn add file" now fails if "file" is already tracked. To filter them we have to mirror the svn manifest in the sink. Tested with svn 1.6.12 and 1.7.4.

docs: don't use :hg: at the beginning of lines in notes (issue3397) It seem like docutils 0.8 interpret ':hg:`command`' roles at the beginning of indented lines in '.. note::' directives as a field that is an invalid argument to the directive. It fails with 'Error in "note" directive: invalid option block.' Docutils 0.7 accepted this arguably incorrect markup. Reflowing the text makes the problem go away. A leading '\ ' could perhaps also be used to mask the problem.

rebase: skip resolved but emptied revisions When rebasing, if a conflict occurs and is resolved in a way the rebased revision becomes empty, it is not skipped, unlike revisions being emptied without conflicts. The reason is: - File 'x' is merged and resolved, merge.update() marks it as 'm' in the dirstate. - rebase.concludenode() calls localrepo.commit(), which calls localrepo.status() which calls dirstate.status(). 'x' shows up as 'm' and is unconditionnally added to the modified files list, instead of being checked again. - localrepo.commit() detects 'x' as changed an create a new revision where only the manifest parents and linkrev differ. Marking 'x' as modified without checking it makes sense for regular merges. But in rebase case, the merge looks normal but the second parent is usually discarded. When this happens, 'm' files in dirstate are a bit irrelevant and should be considered 'n' possibly dirty instead. That is what the current patch does. Another approach, maybe more efficient, would be to pass another flag to merge.update() saying the 'branchmerge' is a bit of a lie and recordupdate() should call dirstate.normallookup() instead of merge(). It is also tempting to add this logic to dirstate.setparents(), moving from two to one parent is what invalidates the 'm' markers. But this is a far bigger change to make. v2: succumb to the temptation and move the logic in dirstate.setparents(). mpm suggested trying _filecommit() first but it is called by commitctx() which knows nothing about the dirstate and comes too late into the game. A second approach was to rewrite the 'm' state into 'n' on the fly in dirstate.status() which failed for graft in the following case: $ hg init repo $ cd repo $ echo a > a $ hg ci -qAm0 $ echo a >> a $ hg ci -m1 $ hg up 0 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ hg mv a b $ echo c > b $ hg ci -m2 created new head $ hg graft 1 --tool internal:local grafting revision 1 $ hg --config extensions.graphlog= glog --template '{rev} {desc|firstline}\n' @ 3 1 | o 2 2 | | o 1 1 |/ o 0 0 $ hg log -r 3 --debug --patch --git --copies changeset: 3:19cd7d1417952af13161b94c32e901769104560c tag: tip phase: draft parent: 2:b5c505595c9e9a12d5dd457919c143e05fc16fb8 parent: -1:0000000000000000000000000000000000000000 manifest: 3:3d27ce8d02241aa59b60804805edf103c5c0cda4 user: test date: Thu Jan 01 00:00:00 1970 +0000 extra: branch=default extra: source=a03df74c41413a75c0a42997fc36c2de97b26658 description: 1 Here, revision 3 is created because there is a copy record for 'b' in the dirstate and thus 'b' is considered modified. But this information is discarded at commit time since 'b' content is unchanged. I do not know if discarding this information is correct or not, but at this time we cannot represent it anyway. This patch therefore implements the last solution of moving the logic into dirstate.setparents(). It does not sound crazy as 'm' files makes no sense with only one parent. It also makes dirstate.merge() calls .lookupnormal() if there is one parent, to preserve the invariant. I am a bit concerned about introducing this kind of stateful behaviour to existing code which historically treated setparents() as a basic setter without side-effects. And doing that during the code freeze.

test-rebase: exhibit revisions which should have been skipped This will be fixed in the next commit. v2: - Display emptied grafted revisions - Use --git flag

transplant: do not rollback on patching error (issue3379) Otherwise, all transplanted revisions are gone and the failing one cannot be fixed (unless it is the first one). I do not know what is the expected behaviour with rollback, probably something pull-like. Non-conflicting cases should work as previously. But something like: $ hg transplant r1 r2 commiting r1 as c1 failing r2 $ hg transplant --continue committing r2 as c2 $ hg rollback would reset the repository to its state before the "transplant --continue" instead of the whole transplant session. To fix this we might need a way to open an existing journal file, not sure this is worth the pain.

patch: fix patch hunk/metdata synchronization (issue3384) Git patches are parsed in two phases: 1) extract metadata, 2) parse actual deltas and merge them with the previous metadata. We do this to avoid dependency issues like "modify a; copy a to b", where "b" must be copied from the unmodified "a". Issue3384 is caused by flaky code I wrote to synchronize the patch metadata with the emitted hunk: if (gitpatches and (gitpatches[-1][0] == afile or gitpatches[-1][1] == bfile)): gp = gitpatches.pop()[2] With a patch like: diff --git a/a b/c copy from a copy to c --- a/a +++ b/c @@ -1,1 +1,2 @@ a +a @@ -2,1 +2,2 @@ a +a diff --git a/a b/a --- a/a +++ b/a @@ -1,1 +1,2 @@ a +b the first hunk of the first block is matched with the metadata for the block "diff --git a/a b/c", then the second hunk of the first block is matched with the metadata of the second block "diff --git a/a b/a", because of the "or" in the code paste above. Turning the "or" into an "and" is not enough as we have to deal with /dev/null cases for each file. We I remove this broken piece of code: # copy/rename + modify should modify target, not source if gp.op in ('COPY', 'DELETE', 'RENAME', 'ADD') or gp.mode: afile = bfile because "afile = bfile" set "afile" to stuff like "b/file" instead of "a/file", and because this only happens for git patches, which afile/bfile are ignored anyway by applydiff(). v2: - Avoid a traceback on git metadata desynchronization

update: fix case-collision with a clean wd and no --clean cbf2ea2f5ca1 introduced some logic to avoid case-collision detection between source and destination revisions when it does not make sense: clean or to be cleaned working directories. Unfortunately, part of it was flawed and the related test was broken by another bug. This patch disables cross revision case collision detection for updates without option or with --check, if the working directory is clean.

It did however require manual setup: The attached script creates such a corruption (you have to add a "import time; time.spleep(3)" in localrepo.addchangegroup before the changegroup manifest are written for example. The test as it is has thus no value as automatic test case. The necessary sleep could be added by a hook, but test-pending.t already tests that.

icasefs: make case-folding collision detection as rename aware (issue3370) if the file in target context causes case-folding collision against one in working context, current implementation aborts merging with it, even thouhg collding one (in target) is the file renamed from collided one (in working). this patch uses file copy information to know whether colliding file is renamed from collided one or not: if so, collision between them is ignored. this patch also avoids collision detection between current context and target context, if working context is clean (with --check/-c) or will be clean (with --clean/-C).

bdiff.bdiff: release the GIL before doing expensive diff operations This means that threaded webservers will have more of a chance of doing something useful while the C extension is busy computing a delta.

revert: show warning when reverting subrepos that do not support revert The warning is similar to the warning that was shown before hgsubrepo revert support was added, with the exception that now the subrepo type is shown. For example, when trying to revert a git subrepo located in "include/mygitsub", the warning message would be: include/mygitsub: reverting git subrepos is unsupported

revset: fix O(n**2) behaviour of bisect() (issue3381)

convert/svn: do not try converting empty head revisions (issue3347) Subversion conversion works by picking trunk and branches heads, computing a revision graph from them and converting the selected commits. By design we fail to convert empty revisions so we have to be careful when discovering the revision graph. In this particular issue, the source svn repository was a partial mirror made by svnsync. The funny part is svnsync preserves all revisions including empty ones. Also, we trusted ra.stat(path, stop).created_rev to give us the latest revision with changes in path history up to stop. This assumption broke at least when path is '', that is the repository root, which always returned 'stop' revision despited being empty. The workaround is to first trust ra.stat() but if the returned revision appear empty, search the whole path history from stop to r1 until some changes are found.

convert/svn: refactor svn_source.latest() with a nested function We will call it more than once for reasons detailed later.

convert/svn: clarify svn_source.latest() stop arg default value stop=0 could pass for a valid default value at first sight.

merge default into stable for 2.2 code freeze

commit: add option to amend the working dir parent The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by "hg status", if there are any. The old commit is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle" and "hg help unbundle" on how to restore it). Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit. It is not possible to amend public changesets (see "hg help phases") or changesets that have children. Behind the scenes, first commit the update (if there is one) as a regular child of the current parent. Then create a new commit on the parent's parent with the updated contents. Then change the working copy parent to this new combined changeset. Finally, strip the amended commit and update commit created in the beginning. An alternative (cleaner?) approach of doing this is suggested here: http://selenic.com/pipermail/mercurial-devel/2012-March/038540.html It is currently not possible to amend merge commits or recursively, this can be added at a later time.

transplant: remove extraneous whitespace

journal: use tryread helper to backup files (issue3375)

opener: introduce tryread helper This makes it easier to follow the common pattern "read a file or give an empty string if it's missing".

tests: add test for fileset 'subrepo' keyword

revset: make matching() work on python 2.4 tuple.index() was apparently added to python 2.6: http://bugs.python.org/issue1696444 Also remove a trailing comma to make check-code.py happy.

revset: use list instead of tuple for compatibility with python before 2.6 'string elements'.split() instead of explicitly typing a list of strings is used. This is done in other parts of Mercurial code, too.

merge with stable

archive: make it work with svn subrepos (issue3308) - _svncommand() in files() returns a tuple since 0ae98cd2a83f not a string. - _svncommand() in filedata() returns a tuple not a string. - "svn list" returns files but also directories. - "svn list" is not recursive by default. I have no idea what happens to svn:externals possibly embedded in the svn subrepository.

largefiles: hide .hglf/ prefix for largefiles in hgweb This makes the manifest view in hgweb match what you see in the working copy and what you get when you download an archive in hgweb.

hgweb: add hook for remapping repository path into virtual paths Extensions such as largefiles can use this to remap files so they appear in the same location as they do in the user's working copy.

tests: add tests for matching keyword This adds a couple of tests for the revset "matching" keyword: 1. Test that the 2nd parameter is optional 2. Test that all the 1st argument can be a revset and that all the supported fields of the 2nd argument work.

revset: speedup matching() by first matching fields that take less time to match This patch sorts the fields that are passed to the matching function so that it always starts by matching those fields that take less time to match. Not all fields take the same amount of time to match. I've done several measurements running the following command: hg --time log -r "matching(1, field)" on the mercurial repository, and where 'field' was each one of the fields accepted by match. In order to avoid the print overhead (which could be different for different fields, given the different number of matches) I used a modified version of the matching() function which always returns no matches. These tests showed that different fields take wildly different amounts of time to match. Particulary the substate field takes up to 25 seconds to match on my machine, compared to the 0.3 seconds that takes to match the phase field or the 2 seconds (approx) that takes to match most fields. With this patch, matching both the phase and the substate of a revision takes the same amount of time as matching the phase. The field match order introduced by this patch is as follows: phase, parents, user, date, branch, summary, files, description, substate An extra nice thing about this patch is that it makes the match time stable.

revset: speedup matching() by stopping the match early if a field does not match Rather than getting all the fields that are being matches from every revision and then comparing them to those of the target revision, compare each field one by one and stop the match as soon as there is a match failure. This can greatly reduce the match time when matching multiple fields. The impact on match time when matching a single field seems negligible (according to my measurements).

revset: make matching keyword not match summary when matching for description

fileset: add "subrepo" fileset symbol This new fileset symbol returns a list of subrepos whose paths match a given pattern. If the argument has no pattern type set, an exact match is performed. If no argument is passed, return a list of all subrepos.

plan9: finalize documentation for next release

localrepo: do not complain about missing journal files

repair: fix missing import introduced by: b5c0c7d0f83fe56240ce7a919581f1cbff4f5ee5

largefiles: fix cat for largefiles (issue3352) This is a fix to largefiles so that 'hg cat' will work correctly when a largefile is specified. As per discussion on Issue 3352: 1) The file will be printed regardless if it is binary or large. 2) The file is downloaded if it is not readily available (not found in the system cache), so that it can be printed. If the download fails, then we abort.

pure: quiesce build warnings The following patch fixes the following warning when building pure: package init file 'mercurial/pure/__init__.py' not found (or not a regular file)

util.h: replace ntohl/htonl with get/putbe32

scmutil: fix systemrcpath regression introduced in f5dd179bfa4a Changeset f5dd179bfa4a introduced a 'root' path component to look for hgrc files, which is used both as an absolute path and a path relative to the <install-root>. The latter one was broken since 'root' was set to an absolute location and the subsequent os.path.join discarded the <install-root> path prefix.

revlog: fix partial revision() docstring (from d7d64b89a65c)

graphlog: fix --follow FILE and relative paths The situation is complicated because filelog() revset uses a match object in relpath mode while follow() revset interprets the filename as a manifest entry.

graphlog: reduce duplication in --follow code

graphlog: add all log options to glog command glog and log -G should be equivalent.

graphlog: implement --hidden

revert: add support for reverting subrepos without --no-backup and/or --all When a subrepo is reverted but --no-backup is not set, call revert on the subrepo that is being reverted prior to updating it to the revision specified in the parent repo's .hgsubstate file. The --all flag is passed down to the subrepo when it is being reverted. If the --all flag is not set, all files that are modified on the subrepo will be reverted.
