bundlerepo: disable filtering of changelog while constructing revision text
This avoids the following error that happened if base revision of bundle file
was hidden. bundlerevlog needs it to construct revision texts from bundle
content as revlog.revision() does.
File "mercurial/context.py", line 485, in _changeset
return self._repo.changelog.read(self.rev())
File "mercurial/changelog.py", line 319, in read
text = self.revision(node)
File "mercurial/bundlerepo.py", line 124, in revision
text = self.baserevision(iterrev)
File "mercurial/bundlerepo.py", line 160, in baserevision
return changelog.changelog.revision(self, nodeorrev)
File "mercurial/revlog.py", line 1041, in revision
node = self.node(rev)
File "mercurial/changelog.py", line 211, in node
raise error.FilteredIndexError(rev)

merge: run update hook after the last wlock release
There were 2 test failures in 3.4-rc when running test-hook.t with the
largefiles extension enabled. For context, the first is a commit hook:

make sure --verbose (and --quiet/--debug etc.) are propagated to the local ui
In both cases, largefiles acquires the wlock before calling into core, which
also acquires the wlock. The first case was fixed in
57f1dbc99631 by ensuring
the hook only runs after the lock has been fully released. The full release is
important, because that is what writes dirstate to the disk, allowing external
hooks to see the result of the update. This simply changes how the update hook
is called, so that it too is deferred until the lock is finally released.
There are many uses of mergemod.update(), but in terms of commands, it looks
like the following commands take wlock while calling mergemod.update(), and
therefore will now have their hook fired at a later time:
backout, fetch, histedit, qpush, rebase, shelve, transplant
Unlike the others, fetch immediately unlocks after calling update(), so for all
intents and purposes, its hook invocation is not deferred (but the external hook
still sees the proper state).
censor: remove meaningless explanation about .hgcensored
There is no code path handling ".hgcensored" in Mercurial source tree.
This meaningless explanation may make users misunderstand about
censor.
parsers: avoid signed integer overflow in calculation of leaf-node index
If v = -INT_MAX - 1, -v would exceed INT_MAX. I don't think this would cause
problems such as
issue4627, but we can't blame it as a compiler bug because
signed integer overflow is undefined in C.
bundle2: disable ouput capture unless we use http (
issue4613 issue4615)
The current bundle2 processing was capturing all output. This is nice as it
provide better meta data about what output what, but this was changing two
things:
1) adding a prefix "remote: " to "other" output during local push (
issue4613)
2) local and ssh push does not provide real time output anymore (
issue4615)
As we are unsure about what form should be used in (1) and how to solve (2) we
disable output capture in this two cases. Output capture can be forced using an
experimental option.
subrepo: propagate the --hidden option to hg subrepositories
With many commands accepting a '-S' or an explicit path to trigger recursing
into subrepos, it seems that --hidden needs to be propagated too.
Unfortunately, many of the subrepo layer methods discard the options map, so
passing the option along explicitly isn't currently an option. It also isn't
clear if other filtered views need to be propagated, so changing all of those
commands may be insufficient anyway.
The specific jam I got into was amending an ancestor of qbase in a subrepo, and
then evolving. The patch ended up being hidden, and outgoing said it would only
push one unrelated commit. But push aborted with an 'unknown revision' that I
traced back to the patch. (Odd it didn't say 'filtered revision'.) A push with
--hidden worked from the subrepo, but that wasn't possible from the parent repo
before this.
Since the underlying problem doesn't actually require a subrepo, there's
probably more to investigate here in the discovery area. Yes, evolve + mq is
not exactly sane, but I don't know what is seeing the hidden revision.
In lieu of creating a test for the above situation (evolving mq should probably
be blocked), the test here is a marginally useful case where --hidden is needed
in a subrepo: cat'ing a file in a hidden revision. Without this change, cat
aborts with:
$ hg --hidden cat subrepo/a
skipping missing subrepository: subrepo
