i18n: use inspect.getsourcelines() to obtain lineno from func or class Before, func must be a function object. I want to make it parse docstring of classes, too.

chg: just take it as EOF if recv() returns 0 hgc->sockfd is a blocking stream socket. recv() should never return 0 other than EOF. See 4fc4b8cc9957 for the original problem.

vfs: use propertycache for open The current open method is currently behaving like a property cache. We use our utility decorator to make this explicit.

check-commit: allow underbars in cffi_-prefix function names It seems reasonable to give cffi functions slightly more verbose names in some circumstances, given the way they interface with C.

bundlerepo: add support for treemanifests in cg3 bundles This is a little messier than I'd like, and I'll probably come back and do some more refactoring later, but as it is this unblocks narrowhg. An alternative approach (which I may do as part of the mentioned refactoring) would be to construct *all* dirlog instances up front, so that we don't have to keep track of the linkmapper method. This would avoid a reference cycle between the bundlemanifest and the bundlerepository, but I was hesitant to do all the work up front like that. With this change, it's possible to do 'hg incoming' and 'hg pull' from bundles in .hg/strip-backup in a treemanifest repository. Sadly, this doesn't make it possible to 'hg clone' one of those (if you do 'hg strip 0'), because the cg3 in the bundle gets written without a treemanifest flag. Since that's going to be an involved refactor in a different part of the code (which I *suspect* won't touch any of the code I've just written here), let's leave it as an idea for Later.

auditvfs: forward options property from nested vfs This was breaking my ability to use treemanifests in bundlerepos, and was deeply mysterious. We should probably just make the options property a formal part of the vfs API, and make it a required construction parameter. Sadly, I don't have time to dive into that refactor right now.

bundlerepo: use supportedincomingversions instead of allsupportedversions Since bundlerepo is really a pull-like operation, this is the correct method to use here.

bundlerepo: introduce method to find file starts and use it This moves us to the modern iter() technique instead of the `while True` pattern since it's easy. Factored out as a function because I'm about to need this in a second place.

bundlerevlog: use for loop over iterator instead of while True The iter() builtin has a neat pattern where you give it a callable of no arguments and a sentinel value, and you can then loop over the function calls like a normal iterator. This cleans up the code a little.

localrepo: jettison now-unused dirlog() method from localrepo

repair: build dirlogs using manifest, rather than repo shortcut method As before, this was rarely used, so let's get rid of the convenience method.

cmdutil: open dirlogs via manifest property, not via repo This was a convenience method that was rarely used, so let's get rid of it.

wirepeer: rename confusing `source` parameter It's named "url" everyplace else this method is defined, so let's be consistent.

develwarn: use the lock helper in local repo We have a helper function to know if a lock is taken. When checking lock usage we now use it instead of manually accessing the locks.

debugextension: change "testedwith" to a list (BC) It wasn't a list since the formatter couldn't process a list. We have no such problem now and the -T option is experimental, so we can change it.

debugextensions: unindent nested if

debugextensions: give short name to util.version()

debugextensions: simply keep testedwith variable as a list There should be no need to distinguish [] and None.

test-treemanifest: ensure manifest command isn't broken I realized we weren't testing this while hunting a broken manifest command bug that ended up being narrowhg's fault.

py3: use unicode literals in pure/osutil.py The first element of _fields_ tuples must be a str in Python 3. Also fix some function calls that were also expecting str.

py3: use unicode literals in crecord.py

py3: use unicode literals in changelog.py collections.namedtuple type and field names must be str in Python 3. Our custom module importer was rewriting them to bytes literals, making this fail. In addition, __slots__ values must also be unicode.

mpatch: write a cffi version of mpatch.patches

mpatch: remove dependency on Python.h in mpatch.c Now all the CPython-related stuff are referenced only from mpatch_module.c with mpatch.c being freely usable from a future cffi module

mpatch: split mpatch into two files

mpatch: provide things that will be exported later with a prefixed name For cffi a bunch of mpatch functions need to be visible through a .h file. This change renames them so it won't create potential c namespace conflicts.

mpatch: change Py_ssize_t to ssize_t in places that will be later copied

discovery: move code to create outgoing from roots and heads changegroup.changegroupsubset() contained somewhat low-level code for constructing an "outgoing" instance from a list of roots and heads nodes. It feels like discovery.py is a more appropriate location for this code. This code can definitely be optimized, as outgoing.missing will recompute the set of changesets we've already discovered from cl.between(). But code shouldn't be refactored during a move, so I've simply inserted a TODO calling attention to that.

bundle2: remove 'experimental.bundle2-exp' boolean config (BC) All users are migrated to 'devel.legacy.exchange', we can clean up the experimental namespace. Marking as (BC) because I know some large installation have bundle2 off and I want to make sure they notice the change.

tests: remove all remaining usage of experimental.bundle2-exp The only remaining usage of the experimental config were enforcing bundle2 on. These are very old remains of when bundle2 was off by default. This was also useful to highlight the fact that this was a bundle2 run and that a bundle1 one was nearby. However, we want a future developer working on bundle3 to notice possible output/behavior change on these tests and take them in account. So we do not enforce bundle2 for these runs. We leave a comment around to make sure dev still notice the bundle1 version.

tests: use 'legacy.exchange' option in various mixed tests The new option will stay around. The experimental option was only meant to be temporary. We update various tests that validate both bundle1 and bundle2 version side by side. This changeset only takes care of enforcing bundle1. The other use of 'experimental.bundle2-exp=True' will be taken care of in the next changeset.
