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.
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>
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.
The fix introduced in 3509b9cf8f86 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.
Brifly explain why rewriting subrepository paths can be necessary.
Explain that relative subrepository paths are made absolute before
rewrite rules are applied.
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 :-)
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.
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 (5cc0d3ba11f9).
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)
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.
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.

Also rename mq.series_dirty into mq.seriesdirty, missed by 9bcf8cbb1bcf, and
without effect since mq.qimport() was setting it already.
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.
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.
The only place where an trailing CR could be meaningful is in the "diff --git"
line as part of a filename, and existing code already rule out this
possibility. Extend the CR/LF filtering to the whole binary hunk.

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.
each help topics describe that patterns are "not rooted" and "rooted"
in themselves, but not describe about each other.
so, this may causes misunderstanding about "rooted"-ness of patterns.
