rev-branch-cache: stop truncating cache file Truncating the file prevent the safe use of mmap. So instead of overwrite the existing data. If more than 20% of the file is to be overwritten, we rewrite the whole file instead. Such whole rewrite is done by replacing the old one with a new one, so mmap of the old file would be affected. This prepare a more aggressive use of mmap in later patches.

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.
