dirstate-v2: Drop cached read_dir results after .hgignore changes Soon we’ll want the status algorithm to be able to skip `std::fs::read_dir` in more cases, notabling when listing unknown files but not ignored files. When ignore patterns change (which we detect by their hash, added to the dirstate-v2 format in a previous changeset), a formerly-ignored file could become unknown without changing its parent directory’s modification time. Therefore we remove any directory mtime from the dirstate, effictively invalidating the existing caches. Differential Revision: https://phab.mercurial-scm.org/D10907

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.
