transaction: clarify the "quick abort" scenario Right now, the transaction has a code-pass to do a "quick abort" that skip most¹ (too much) of the logic when the right condition are detected² We are about to improve this logic in multiple aspect. We clarify the code first. The conditional return in `_can_quick_abort` looks a bit weird because we are about to make them more complex very soon. [1] actually too much [2] actually not often enough

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.
