overlayworkingctx: remove misleading trailing slash from directory pattern The paths passed into the matcher are normalized (this applies to include patterns and regular patterns, and to both glob kind and path kind), so the regex for input "foo/" ended up being "foo(?:/|$)". Once we have a (recursive) pattern kind only for directories, we could switch to that here and remove the "mfiles[0] == path" check. Until then, let's at least make it not misleading.

overlayworkingctx: fix file/dir audit to be repo-relative Before this patch, test-rebase-inmemory.t would stop erroring out about the conflict if you added a "cd a" before line 252. That was because a glob matcher (which are relative) was unintentionally used. That happened because the matcher was given "include" patterns (not regular patterns), and "include" patterns are always glob by default (i.e. unless you write them including the kind prefix). IOW, the "default='path'" argument passed to ctx.match() was ignored. Differential Revision: https://phab.mercurial-scm.org/D6223

messages: replace some instances of "folder" by "directory" I'm pretty sure this is our preferred term. Differential Revision: https://phab.mercurial-scm.org/D6222

match: fix re2 compability broken in 2e2699af5649 When using re2, we call test_match() instead of match() on the compiled regex object. While match() returns a matcher object or None, test_match() returns True or False. So since 2e2699af5649 running test on a machine with a re2 install fails in many places. Instead we make the code a bit more general and everything goes back to normal.

cext: cast s# arguments of Py_BuildValue() to Py_ssize_t The doc doesn't state that "s#" of Py_BuildValue() is controlled by PY_SSIZE_T_CLEAN (unlike the one for PyArg_ParseTuple()), but actually it's switched to Py_ssize_t. https://docs.python.org/2/c-api/arg.html#c.Py_BuildValue https://github.com/python/cpython/blob/2.7/Python/modsupport.c#L432 Follow up for b01bbb8ff1f2 and 896b19d12c08.

remotefilelog: correctly reject wdir filenodes This fixes `hg grep -r 'wdir()'` when remotefilelog is enabled and the working directory contains uncommitted modifications. Differential Revision: https://phab.mercurial-scm.org/D6217

remotefilelog: add tests of `hg grep -r 'wdir()'` This demonstrates how remotefilelog breaks grepping dirtied working directories. A future change will introduce a fix. Differential Revision: https://phab.mercurial-scm.org/D6216

config: read configs from directories in lexicographical order Mercurial currently reads the .rc files specified in HGRCPATH (and the system-default paths) in directory order, which is unspecified. My team at work maintains a set of .rc files. So far there has been no overlap between them, so we had not noticed this behavior. However, we would now like to release some common .rc files and then have another one per plaform with platform-specific overrides. It would be nice if we can determine the load order by choosing names carefully. This patch enables that by loading the .rc files in lexicographical order. Before this patch, the added test case would consistently say "30" on my file system (whatever I have -- some Linux FS). Differential Revision: https://phab.mercurial-scm.org/D6193

remotefilelog: fix crash on `hg addremove` of added-but-deleted file If you `hg add` a file and then delete it from disk, and then run `hg addremove`, the file ends up in the "removed" set that gets passed to the findrenames() override. We then crash because the file is not in the working copy parent. This patch fixes that. Differential Revision: https://phab.mercurial-scm.org/D6194

packaging: ensure that --python is an absolute path when building on Windows For whatever reason, even though only python2 is on PATH, passing `python.exe` causes the later check that it's not py3 to bail out.
