rust-status: only visit parts of the tree requested by the matcher This is an optimization that the matcher is designed to support, but we weren't doing it until now. This is primarily relevant for supporting "hg status [FILES]", where this optimization is crucial for getting good performance (without this optimization, that command will still scan the entire tree, and just filter it down after the fact). When this optimization fires we have to return false from traverse_fs_directory_and_dirstate, representing that that part of the tree *might* have new files which we didn't see because we skipped parts of it. This only affects the cached result of the status, and is necessary to make future status operations (which might use a different matcher) work properly.

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.

Notes for packagers

Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
