rust-index: honour incoming using_general_delta in `deltachain`
It looks to be a leftover from some past, but the C index considers
only the value passed from Python whereas up to now the Rust index
was using the value of its attribute.
As a middle ground, we make this argument of `deltachain` optional from
the Python side, with the Rust implementation only defaulting to its
attribute. This way, we reduce false leads when a difference in results
is spotted.
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.
