revlog: use radix tree also for matching keys shorter than 4 hex digits I don't know what the reason for the 4-digit limit was, and I can't think of any real disadvantages of using the radix tree also when the requested minimum length is short. This speeds up `hg log -T '{shortest(node,1)}\n'` from 2m16s to 4.5s by making that not fall back to pure code. Differential Revision: https://phab.mercurial-scm.org/D3453

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
