worker: avoid reading 1 byte at a time from the OS pipe Apparently `pickle.load` does a lot of small reads, many of them literally 1-byte, so it benefits greatly from buffering. This change enables the buffering, at the cost of more complicated interaction with the `selector` API. On one repository with ~400k files this reduces the time by about ~30s, from ~60 to ~30s. The difference is so large because the actual updating work is parallellized, while these small reads are bottlenecking the central hg process.

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.
