packaging: rework version detection and declaration (
issue4912)
Previously the -rc in our rc tags got dropped, meaning that those
packages looked newer to the packaging system than the later release
build. This rectifies the issue, though some damage may already have
been done on 3.6-rc builds.
I'm mostly cargo-culting the RPM version format - there don't appear
to be rules for RPM about how to handle this. Hopefully an RPM
enthusiast can fix up what I've done as a followup.
hgweb: escape class keyword when used as a js object property (
issue4913)
localrepo: discard objects in _filecache at transaction failure (
issue4876)
'repo.invalidate()' deletes 'filecache'-ed properties by
'filecache.__delete__()' below via 'delattr(unfiltered, k)'. But
cached objects are still kept in 'repo._filecache'.
def __delete__(self, obj):
try:
del obj.__dict__[self.name]
except KeyError:
raise AttributeError(self.name)
If 'repo' object is reused even after failure of command execution,
referring 'filecache'-ed property may reuse one kept in
'repo._filecache', even if reloading from a file is expected.
Executing command sequence on command server is a typical case of this
situation (
5c0f5db65c6b also tried to fix this issue). For example:
1. start a command execution
2. 'changelog.delayupdate()' is invoked in a transaction scope
This replaces own 'opener' by '_divertopener()' for additional
accessing to '00changelog.i.a' (aka "pending file").
3. transaction is aborted, and command (1) execution is ended
After 'repo.invalidate()' at releasing store lock, changelog
object above (= 'opener' of it is still replaced) is deleted from
'repo.__dict__', but still kept in 'repo._filecache'.
4. start next command execution with same 'repo'
5. referring 'repo.changelog' may reuse changelog object kept in
'repo._filecache' according to timestamp of '00changelog.i'
'00changelog.i' is truncated at transaction failure (even though
this truncation is unintentional one, as described later), and
'st_mtime' of it is changed. But 'st_mtime' doesn't have enough
resolution to always detect this truncation, and invalid
changelog object kept in 'repo._filecache' is reused
occasionally.
Then, "No such file or directory" error occurs for
'00changelog.i.a', which is already removed at (3).
This patch discards objects in '_filecache' other than dirstate at
transaction failure.
Changes in 'invalidate()' can't be simplified by 'self._filecache =
{}', because 'invalidate()' should keep dirstate in 'self._filecache'
'repo.invalidate()' at "hg qpush" failure is removed in this patch,
because now it is redundant.
This patch doesn't make 'repo.invalidate()' always discard objects in
'_filecache', because 'repo.invalidate()' is invoked also at unlocking
store lock.
- "always discard objects in filecache at unlocking" may cause
serious performance problem for subsequent procedures at normal
execution
- but it is impossible to "discard objects in filecache at unlocking
only at failure", because 'releasefn' of lock can't know whether a
lock scope is terminated normally or not
BTW, using "with" statement described in PEP343 for lock may
resolve this ?
After this patch, truncation of '00changelog.i' still occurs at
transaction failure, even though newly added revisions exist only in
'00changelog.i.a' and size of '00changelog.i' isn't changed by this
truncation.
Updating 'st_mtime' of '00changelog.i' implied by this redundant
truncation also affects cache behavior as described above.
This will be fixed by dropping '00changelog.i' at aborting from the
list of files to be truncated in transaction.
demandimport: fix TypeError when importing Python regex library (
issue4920)
bundle2: attribute remote failures to remote (
issue4788)
Before bundle2, hook output from hook failures was prefixed with
"remote: ". Up to this point with bundle2, the output was converted to
the message to print in an Abort exception. This had 2 implications:
1) It was unclear whether an error message came from the local repo
or the remote
2) The exit code changed from 1 to 255
This patch changes the handling of error:abort bundle2 parts during push
to prefix the error message with "remote: ". This restores the old
behavior.
We still preserve the behavior of raising an Abort during bundle2
application failure. This is a regression from pre-bundle2 because the
exit code changed.
Because we no longer raise an Abort with the remote's message, we needed
to insert a message for the new Abort. So, I invented a new error
message for that. This is another change from pre-bundle2. However, I
like the new error message because it states unambiguously who aborted
the push failed, which I think is important for users so they can decide
what's next.
tests: add tests for remote hook output (
issue4788)
The added tests don't agree in their output. This demonstrates a
difference in `hg push` behavior between pre-bundle2 and bundle2.
A subsequent patch will attempt to restore some of the pre-bundle2
behavior to bundle2.
debugrevlog: cope with empty revlog files
I have no idea where it came from, but my clone of Mercurial has an
empty filelog for `contrib/hgfixes/__init__.py` - it's *valid*, just
contains no nodes. Without this change, debugrevlog crashes with a
zero division error.
largefiles: don't mute and obfuscate http errors when putlfile fails
'unexpected putlfile response: None' when an http error occurs is not very
helpful.
Instead, leave the handling of urllib2.HTTPError exceptions to other layers.
