rust: sort dependencies entries in Cargo.toml I should probably write a test to enforce this... Differential Revision: https://phab.mercurial-scm.org/D6398

py3: make contrib/testparseutil.py to work on str(unicodes) contrib/check-code work on unicodes and call functions from testparseutil.py which before this patch used to work on bytes. This path removes that inconsistency and make testparseutil.py work on unicodes. This makes test-check-code.t and test-contrib-check-code.t work on Python 3 again.

rust-filepatterns: call new Rust implementations from Python This change adds the import to the `rust-cpython` bindings and uses them when appropriate. A wrapper function has been defined in the case of `_regex` to keep this patch simple. Differential Revision: https://phab.mercurial-scm.org/D6273

rust-filepatterns: add `rust-cpython` bindings for `filepatterns` This change adds the `rust-cpython` interface for top-level functions and exceptions in the filepatterns module. Contrary to the Python implementation, this tries to have finer-grained exceptions to allow for better readability and flow control down the line.

rust-filepatterns: add a Rust implementation of pattern-related utils This change introduces Rust implementations of two functions related to pattern handling, all located in `match.py`: - `_regex` - `readpatternfile` These utils are useful in the long-term effort to improve `hg status`'s performance using Rust. Experimental work done by Valentin Gatien-Baron shows very promising improvements, but is too different from the current Mercurial core code structure to be used "as-is". This is the first - albeit very small - step towards the code revamp needed down the line. Two dependencies were added: `regex` and `lazy_static`. Both of them will be useful for a majority of the Rust code that will be written, are well known and maintained either by the Rust core team, or by very frequent contributors.

exchange: don't take wlock if bookmarks are stored in .hg/store/ If bookmarks are stored in .hg/store/, there is no need for the wlock(). Differential Revision: https://phab.mercurial-scm.org/D6388

bookmarks: keep bookmarks in .hg/store if new config set Bookmarks storage consists of two parts: (1) the set of bookmarks and their positions, and (2) the current bookmark. The former can get updated by exchange, while the latter cannot. However, they are both stored in directly .hg/ and protected by repo.wlock(). As a result, ugly workarounds were needed. This patch introduces a new config option to store the set of bookmarks and their positions in .hg/store/ but still storing the current bookmark directory in .hg/. The config option only takes effect at repo creation time. It results in a new requirement being set. Differential Revision: https://phab.mercurial-scm.org/D6387

log: flag topo-sorted set as such This isn't required right now, but revs.istopo() should return True.

copies: fix duplicatecopies() with overlay context The reasoning for this check is in 78d760aa3607 (duplicatecopies: do not mark items not in the dirstate as copies, 2013-03-28). The check was then moved to workingfilectx in 754b5117622f (context: add workingfilectx.markcopied, 2017-10-15) and no corresponding check was added later when overlayworkingfilectx was added. Rather than adding the check there, this patch adds a more generic check on the callers side and removes the check in workingfilectx.markcopied().

exthelper: add some semi-useful trace logs It'd be nice to make the trace functions a little better-named in the output, but I'm not sure how much better we can do without overhead. This at least lets you see if a single reposetup function is eating all the time or if it's spread over all of them. I needed this because Google's uber-extension has a long load time and I wasn't sure where the problem was. Differential Revision: https://phab.mercurial-scm.org/D6381

tests: fix share test to actually share the repo "repo2" is clearly meant to be a share from "repo1" but without sharing bookmarks. However, `hg unshare` was called in the repo, so it had become completely unrelated and thus not testing what it was supposed to test. Differential Revision: https://phab.mercurial-scm.org/D6385
