subrepo/svn: cache _wcrev() value in merge()

subrepo/svn: fix checked out rev number retrieval (issue2968) The initial version was to take the "Revision" field from svn info. It works but produces false positive when parent paths are being moved or unrelated changes are being committed, causing it to change while the svn checkout itself remains the same. To avoid spurious commit, we took "Revision" and "Last Changed Rev" for general comparison and kept the latter to answer "what is your revision?" question. This is better but fails when the subrepo path exists at "Revision" but not at "Last Changed Rev". This patch adds a check for this, and returns "Revision" if the path does not exist. We try to avoid doing this as much as possible at it implies an extra, *remote* call.

amend: fix copy records handling (issue3410) Messing with the dirstate before the intermediate commit seems error prone. Instead, commit and recompute the copies with copies.pathcopies(), then use that with commitctx(). Since copies.pathcopies() does not support file replacement very well, the whole .renamed() condition in samefile() is removed and the "file replacement caused by differing copy source" effect is discarded. Test shamelessly stolen from Idan Kamara <idankk86@gmail.com>

test-commit-amend: exhibit an --amend weirdness The weirdness is --amend let you replace one file with another with same data and flags if the new file copy record differ from the one in the parent revision. In theory, there is no problem with this kind of thing, subversion supports it, but here we see log and status disagree. The reason is log reads the copy record from the filelog, while status calls copies.pathcopies() which eventually invokes some expensiveness argument to discard this case (copies.py, _forwardcopies(), line 132). Since the next patch will side with pathcopies(), I prefer to call this behaviour a bug.

localrepo: add setparents() to adjust dirstate copies (issue3407) The fix introduced in eab9119c5dee was only partially successful. It is correct to turn dirstate 'm' merge records into normal/dirty ones but copy records are lost in the process. To adjust them as well, we need to look in the first parent manifest to know which files were added and preserve only related records. But the dirstate does not have access to changesets, the logic has to moved at another level, in localrepo.

test-rebase-parameters: more tests for revset/opts - --source and revset - --base and revset - --rev and revset - --rev and --source combination - --rev and --base combination

help/config: expand [subpaths] help Brifly explain why rewriting subrepository paths can be necessary. Explain that relative subrepository paths are made absolute before rewrite rules are applied.

doc: update copyright years to 2012 I sometimes look at a piece of software and if the man page says "Copyright 2004", then I'm inclined to think that the project is stale or that the authors are lazy. Neither is good publicity for us :-)

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.
