revset: fix keyword arguments to go through optimization process Before, a keyvalue node was processed by the last catch-all condition of _optimize(). Therefore, topo.firstbranch=expr would bypass tree rewriting and would crash if an expr wasn't trivial.

help: add example of '[templates]' usage V2: - move from shortest() with minlength 8 to minlength 4 - mention [templates] in config.txt - better describe the difference between [templatealias] and [templates] V3: - choose a better example template

exchange: correctly specify url to unbundle (issue5145) This parameter is slightly confusingly named in wireproto, so it got mis-specified from the start as 'push' instead of the URL to which we are pushing. Sigh. I've got a patch for that which I'll mail separately since it's not really appropriate for stable. Fixes a regression in bundle2 from bundle1.

convert: move svn config initializer out of the module level The svn_config_get_config config call was being called at the module level, but had the potential to throw permission denied errors if ~/.subversion/servers was not readable. This could happen in certain test environments where the user permissions were very particular. This prevented the remotenames extension from loading, since it imports convert's hg module, which imports convert's subversion module, which calls this. The config is only ever used from this one constructor, so let's just move it in to there.

doc: make previous line of certificate example end with "::" Before this patch, certificate example is formatted just as normal text.

doc: fix incorrect use of rst hg role in help text

doc: use field rst syntax to show keywords in debugdeltachain help correctly List of available keywords is well formatted as a list of fields in doc string, but is formatted as just normal text in online help output.

revset: refactor to make xgettext put i18n comments into hg.pot file xgettext expects both "_()" and (a part of) text to be placed at just next line of "i18n:" comment.

doc: omit useless _() invocation In this case, column positioning isn't needed for i18n, too. Maybe, check-code warning "missing _() in ui message" caused this useless _() invocation in 92d37fb3f1aa.

demandimport: avoid infinite recursion at actual module importing (issue5304) Before this patch, importing C module on Windows environment causes infinite recursion call, if py2exe is used with -b2 option. At importing C module "a.b", extra hooking by zipextimporter of py2exe causes: 0. assumption before accessing "b" of "a": - built-in module object is created for "a", (= "a" is actually imported) - _demandmod is created for "a.b" as a proxy object, and (= "a.b" is not yet imported) - an attribute "b" of "a" is initialized by the latter 1. invocation of __import__ via _hgextimport() in _demandmod._load() for "a.b" implies _demandimport() for "a.b" This is unintentional, because _demandmod might be returned by _hgextimport() instead of built-in module object. 2. _demandimport() at (1) is invoked with not context of "a", but context of zipextimporter Just after invocation of _hgextimport() in _demandimport(), an attribute "b" of the built-in module object for "a" is still bound to the proxy object for "a.b", because context of "a" isn't updated by actual importing "a.b". even though the built-in module object for "a.b" already appears in sys.modules. Therefore, chainmodules() returns _demandmod for "a.b", which is gotten from the attribute "b" of "a". 3. processfromitem() on "a.b" causes _demandmod._load() for "a.b" again _demandimport() takes context of "a" in this case. Therefore, attributes below are bound to built-in module object for "a.b", as expected: - "b" of built-in module object for "a" - _module of _demandmod for "a.b" 4. but _demandimport() invoked at (1) returns _demandmod object because _demandimport() just returns the object returned by chainmodules() at (3) above. 5. then, _demandmod._load() causes infinite recursion call _demandimport() returns _demandmod for "a.b", and it is "self" at _demandmod._load(). To avoid infinite recursion at actual module importing, this patch uses self._module, if _hgextimport() returns _demandmod itself. If _demandmod._module isn't yet bound at this point, execution should be aborted, because actual importing failed. In this patch, _demandmod._module is examined not on _demandimport() side, but on _demandmod._load() side, because: - the former has some exit points - only the latter uses _hgextimport(), except for _demandimport() BTW, this issue occurs only in the code path for non .py/.pyc files in zipextimporter (strictly speaking, in _memimporter) of py2exe. Even if zipextimporter is enabled, .py/.pyc files are handled by zipimporter, and it doesn't imply unintentional _demandimport() at invocation of __import__ via _hgextimport().

packagelib: do not remove packages directory in hggetversion (issue5262) People running packages related code probably do care about the content of this directory. In particular this shound fix the rpm builder process.

make: introduce a target to clean everything but packages Removing the 'packages' directory makes nightly builder life much harder.

url: avoid re-issuing incorrect password (issue3210) Some draconian IT setups lock accounts after a small number of incorrect password attempts. Mercurial's implementation of the urllib2 authentication was causing 5 retry attempts with the same credentials, without prompting the user. The code was attempting to check whether the authorization token had changed, but unfortunately was reading the misleading 'headers' member of the request instead of using the 'get_header' accessor. Modelled on fix for Python issue 8797: https://bugs.python.org/issue8797 https://hg.python.org/cpython/rev/30e8a8f22a2a

date: accept broader range of ISO 8601 time specs The "normal" ISO date/time includes a T between date and time. It also allows dropping the colons and seconds from the timespec. Add new patterns for these forms as well as tests.

date: parse ISO-style Z and +hh:mm timezone specs

date: refactor timezone parsing We want to be able to accept ISO 8601 style timezones that don't include a space separator, so we change the timezone parsing function to accept a full date string and return both the offset and the non-timezone portion.

tests: glob over ssl error We do this in the rest of the file. This bad line was introduced in 3fde328d0913.

keyword: avoid traceback when kwdemo is run outside a repo f0564402d059 causes a fatal AttributeError if kwdemo is run outside a repo because in the temporary repo creation repo is None and therefore cannot have a baseui attribute. In this case fall back to using ui. Add test case.

cmdutil: warnings not issued in cat if subrepopath overlaps Previously a subrepository "sub" would cause no warnings to be issued for a file "subnot/a", if it's not present in the corresponding changeset when calling: hg cat subnot/a

graft: use opts.get() consistently Make life easier for extension writers.

sslutil: work around SSLContext.get_ca_certs bug on Windows (issue5313) SSLContext.get_ca_certs() can raise "ssl.SSLError: unknown error (_ssl.c:636)" on Windows. See https://bugs.python.org/issue20916 for more info. We add a try..except that swallows the exception to work around this bug. If we encounter the bug, we won't print a warning message about attempting to load CA certificates. This is unfortunate. But there appears to be little we can do :/

extdiff: escape path for docstring (issue5301) The existing code (a) assumed path would be specified in encoding.encoding and (b) assumed unicode() objects wouldn't cause other parts of Mercurial to blow up. Both are dangerous assumptions. Since we don't know the encoding of path and can't pass non-ASCII through docstrings, just escape the path and drop the early _(). Will have to suffice until we can teach docstrings to handle UTF-8b escaping. This has the side-effect that the line containing the path is now variable by the time it reaches _() and thus can't be translated.

update: fix bug when update tries to modify folder symlink In 1e4512eac59e0114bc60ecbcdc4157fc0fa0439d, I introduced a new bug: when a symlink points to a folder in commit A and to another folder in commit B, while updating from A to B, Mercurial will try to use removedir on this symlink, which will fail. This is a very bad bug, since it basically renders symlinks to folders unusable in repos. Added test case fails without a fix and passes with it.

templatekw: fix join format of parents keyword (issue5292) Since the default joinfmt() can't process a dict of multiple keywords, we need a dedicated joinfmt for showparents(). Unlike revset(), parents are formatted as '{rev}:{node|formatnode}' by default. We copy the default formatting just like showextras() and showfilecopies() do.

templatekw: fix join format of revset() function It's been broken since e4609ec959f8, which made makemap() return a dict of multiple keywords. Because the default joinfmt() randomly picks one item from a dict, we have to make revset() select d[name] explicitly.

sslutil: improve messaging around unsupported protocols (issue5303) There are various causes for the inability to negotiate common SSL/TLS protocol between client and server. Previously, we had a single, not very actionable warning message for all of them. As people encountered TLS 1.0 servers in real life, it was quickly obvious that the existing messaging was inadequate to help users rectify the situation. This patch makes the warning messages much more verbose in hopes of making them more actionable while simultaneously encouraging users and servers to adopt better security practices. This messaging flirts with the anti-pattern of "never blame the user" by signaling out poorly-configured servers. But if we're going to disallow TLS 1.0 by default, I think we need to say *something* or people are just going to blame Mercurial for not being able to connect. The messaging tries to exonerate Mercurial from being the at fault party by pointing out the server is the entity that doesn't support proper security (when appropriate, of course).

sslutil: capture string string representation of protocol This will be used in a subsequent patch to improve messaging.

sslutil: allow TLS 1.0 when --insecure is used --insecure is our psuedo-supported footgun for disabling connection security. The flag already disables CA verification. I think allowing the use of TLS 1.0 when specified is appropriate.

hg: copy [hostsecurity] options to remote ui instances (issue5305) TIL that ui instances for remote/peer repos don't automagically inherit config options from .hg/hgrc files. This patch makes remote ui instances inherit options from the [hostsecurity] section. We were already inheriting options from [hostfingerprints] and [auth]. So adding [hostsecurity] to the list seems appropriate.

rbc: fix superfluous rebuilding from scratch - don't abuse self._rbcnamescount The code used self._rbcnamescount as if it was the length of self._names ... but actually it is just the number of good entries on disk. This caused the cache to be populated inefficiently. In some cases very inefficiently. Instead of checking the length before lookup, just try a lookup in self._names - that is also in most cases faster. Comments and debug messages are tweaked to help understanding the issue and the fix.

rbc: test case for incorrect and too aggressive invalidation of invalid caches

util: better handle '-' in version string (issue5302) versiontuple() was previously only splitting on '+' and strings like "3.9-rc" were causing it to misreport the version as (3, None). By splitting on either '+' or '-' we can handle our version strings with "-rc" in them.

convert: update use of deprecated bzrlib property The inventory property was deprecated in favor of root_inventory in bzr 2.5.0. Current version is 2.7.0. I noticed this when testing locally on Python 2.6.9, which has warnings turned on by default. The failure that occurs without this patch can be seen on Python 2.7 by running with warnings enabled: $ PYTHONWARNINGS=::DeprecationWarning make 'test-convert-bzr*'

rebase: turn rebase revs into set before filtering obsolete When the inhibit extension from mutable-history is enabled, it attempts to iterate over the rebaseset to prevent the nodes being rebased from being marked obsolete. This happens at the same time as rebase's _filterobsoleterevs function trying to iterate over the rebaseset to figure out which ones are obsolete. The two of these iterating over the same revset generatorset cause a 'generator already executing' exception. This is probably a flaw in the revset implementation, since iterating over the same set twice should be supported. This regression was introduced in 5d16ebe7b14, since it changed _filterobsoleterevs to be called before the rebaseset was turned into a set(). For now let’s just make the rebaseset an actual set again before calling that function. This was caught by the inhibit tests.

commandserver: update comment about setpgid Now setpgid has 2 main purposes: better handling for terminal-generated SIGTSTP, SIGINT, and process-exit-generated SIGHUP. Update the comment to explain things more clearly.

chg: forward SIGINT, SIGHUP to process group These signals are meant to send to a process group, instead of a single process: SIGINT is usually emitted by the terminal and sent to the process group. SIGHUP usually happens to a process group if termination of a process causes that process group to become orphaned. Before this patch, chg will only forward these signals to the single server process. This patch changes it to the server process group. This will allow us to properly kill processes started by the forked server process, like a ssh process. The behavior difference can be observed by setting SSH_ASKPASS to a dummy script doing "sleep 100" and then run "chg push ssh://dest-need-password-auth". Before this patch, the first Ctrl+C will kill the hg process while ssh-askpass and ssh will remain alive. This patch will make sure they are killed properly.
