dirstate-v2: Reuse existing nodes when appending to a data file When writing a dirstate in v2 format by appending to an existing data file, nodes that are still "unparsed" from the previous on-disk representation have been unchanged and can therefore be reused. This makes the new data point to previously-existing data for tree nodes. Differential Revision: https://phab.mercurial-scm.org/D11095

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.
