changelog-v2: add a configuration to disable rank computation
We encountered a graph where rank computation was pathologically slow. We add an
option to disable this computation while this is getting fixed.
Disabling the rank computation should allow for testing other changelog-v2
features undisturbed (like changeset-based copy tracing).
I am purposely not adding a test for the new non-default code path, as this is
a temporary work around of an experimental feature.
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.
