usage: configure uncompressed chunk cache through resource configuration
Let's use this new concept for what it is meant for.
This provides a sizable speed up for reading multiple revision for some complexe
repositories.
### data-env-vars.name = pypy-2018-08-01-zstd-sparse-revlog
# benchmark.name = hg.perf.read-revisions
# benchmark.variants.order = reverse
memory-medium: 1.892400
memory-high: 1.722934 (-8.61%)
# benchmark.variants.order = default
memory-medium: 1.751542
memory-high: 1.589340 (-9.49%)
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.
