revlog: create a iteration of a _InnerRevlog object within the revlog
The goal of this object is to isolate a sub-API that can be implemented by a
compiled object (e.g. Rust). So the boundary of this object will be arbitrary
depending of what can we easily implemented in the Compiled code.
For now, we start simple, and move the code that manage the IO objects in the
inner object. More will come in the coming changesets.
Note: the object definition could live in the different module to thin the
`revlog.py` file, however there are other better candidate for extraction first
and I have enought patch stacked on top of the this one for the split in this
patch not to be worth it. So I leave this to future me.
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.
