errors: make exit codes class variables instead Kyle pointed out to me that we can simply make the exit codes class variables. Python provides some magic for making them accessible as instance variables. This also makes it easier to let subclasses of existing errors override the exit codes by letting them simply define their own values as class variables. That means that there's no need to pass them into the superclass's constructor arguments, so the superclass doesn't need to expose the them as arguments. (Making a subclass set a different exit code for a subclass of `StorageError` was actually the goal with my recent series.) Differential Revision: https://phab.mercurial-scm.org/D10758

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.
