Question

I have local machine (A), testing server (B) and repository server (C).
I have following workflow:

1. Code something on A
2. Mirror changes to test machine B
3. If it works well commit from B to C

For now, I use rsync for mirroring, but since repository grows it takes some time (~10 sec) to get file list from B. I want to use Git instead of rsync, because it would be much faster and I would have local history along with repository C.

The problem is I haven’t found any way to do live-mirroring with git. I can do

git add . && git commit -m "mirroring" && git push

on local machine, but what about server?

Is cronjob for every few second

git checkout | awk '{print $2;}' | git checkout

a right way?

P. S.: I new in git and maybe there is more appropriate tools for this job.

Live-mirroring with Git can be done via git hooks.

You can set up update hook, which can execute actions rigt after a branch was updated. Set this hook up at server B. The hook will be launched at B‘s site each time you push changes to it. Inside this hook, you may just push changes forward to C (for which you should create a remote). The hook would look like this:

#!/bin/bash
git push remote-of-c $3:$1
[ $? -ne 0 ] && { 
  echo 'Mirroring failed, check server settings and try again.'
  exit 1
}

So each time you update B, C will also get updated. If something failed during that push, you’ll see the relevant messages in console, and your initial push won’t succeed. That’s what’s called “mirroring”, isn’t it?
