relnotes: mention removed support for mixed log graph lines This adds release notes for 264a2cbb25d0 (graphmod: remove support for graph lines mixing parent/grandparent styles (BC), 2018-10-16). Differential Revision: https://phab.mercurial-scm.org/D6407

tests: fix test-clonebundles on recent openbsd I guess openbsd feels like it needs to stringify this errno in lowercase and omit the "host" part of "hostname. Okay. Reported in a big test diff talking about libressl, see 6122. I'm not flagging this because most of that issue is about a libressl string change, so this doesn't really make a big difference there.

rust-python3: compatibility fix for integer conversion On python3, `to_py_object()` on the usize gives us a PyLong, whereas it is the generic `PyObject` already on python2, which fits the `py.None()` default value. Upcasting to `PyObject` explicitely in all cases solves the issue. Differential Revision: https://phab.mercurial-scm.org/D6396

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
