rust-repo: make `Send` by not storing functions in `LazyCell`...
rust-repo: make `Send` by not storing functions in `LazyCell` We (Google) want to use `Repo` in a context where we can store it in `Mutex<Repo>`. However, that currently doesn't work because it's not `Send` because the `LazyCell` initialization functions are not `Send`. It's easy to fix that by passing them to the `get_or_init()` and `get_mut_or_init()` functions. We'll probably also want `Repo` to be `Send` (and even `Sync`) in core later, so this seems like a step in the right direction. Differential Revision: https://phab.mercurial-scm.org/D12582

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.
