rust: Parse "subinclude"d files along the way, not later...
rust: Parse "subinclude"d files along the way, not later When parsing a `.hgignore` file and encountering an `include:` line, the included file is parsed recursively right then in a depth-first fashion. With `subinclude:` however included files were parsed (recursively) much later. This changes it to be expanded during parsing, like `.hgignore`. The motivation for this is an upcoming changeset that needs to detect changes in which files are ignored or not. The plan is to hash all ignore files while they are being read, and store that hash in the dirstate (in v2 format). In order to allow a potential alternative implementations to read that format, the algorithm to compute that hash must be documented. Having a well-defined depth-first ordering for the tree of (sub-)included files makes that easier. Differential Revision: https://phab.mercurial-scm.org/D10834

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.
