rhg: desambiguate status without decompressing filelog if possible When status is unsure based on `stat()` and the dirstate if a file is clean or modified, we need to compare it against the filelog. This comparison can skip looking at contents if the lengths differ. This changeset optimize this further to deduce what we can about the length if the filelog without decompressing it or resolving deltas. Differential Revision: https://phab.mercurial-scm.org/D11965

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

Build environment variables:

* HGPATH: the path to the hg executable to call when CHGHG and HG are not set,
instead of "hg"
* HGPATHREL=1: when CHGHG and HG are not set, the hg executable will be ./hg
relative to the chg executable. Only works on linux, falls back to "hg"
otherwise.
