revset: use phasecache.getrevset to calculate public() Other revsets like secret(), draft(), _nonpublic() are using phasescache.getrevset already. The latter is more efficient after D1606. So let's migrate the public() revset function too. Tested using: $ hg debugshell --hidden --cwd hg-committed` In [1]: %timeit len(repo.revs('public()')) * Before D1606: 10 loops, best of 3: 22.5 ms per loop * Before this change, after D1606: 10 loops, best of 3: 28.6 ms per loop * After this change: 10 loops, best of 3: 20.2 ms per loop Therefore `public()` revset becomes even slightly faster after the data structure change by D1606. A similar performance win could also be observed on a large repo. A side effect is `phasecache.getrevset` needs to take a `subset` parameter. That was added with a default value so it won't cause BC issues. Differential Revision: https://phab.mercurial-scm.org/D1620

cHg
===

A fast client for Mercurial command server running on Unix.

Install:

 $ make
 $ make install

Usage:

 $ chg help                 # show help of Mercurial
 $ alias hg=chg             # replace hg command
 $ chg --kill-chg-daemon    # terminate background server

Environment variables:

Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:

 * configuration files are reloaded automatically by default.
 * CHGHG or HG specifies the path to the hg executable spawned as the
   background command server.

The following variables are available for testing:

 * CHGDEBUG enables debug messages.
 * CHGSOCKNAME specifies the socket path of the background cmdserver.
 * CHGTIMEOUT specifies how many seconds chg will wait before giving up
   connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60
