A caching Git HTTP server

Mirror remote repositories and serve them over HTTP, automatically updating them as needed.

Currently supported client operations are fetch and clone. Authentication to the upstream repository is always enforced (for now, only HTTP Basic is supported), but public repositories can be used as well.

Usage

Usage:
  git-cache-http-server.js [options]

Options:
  -c,--cache-dir <path>   Location of the git cache [default: /var/cache/git]
  -p,--port <port>        Bind to port [default: 8080]
  -h,--help               Print this message
  --version               Print the current version

The upstream remote is extracted from the URL, taking the first component as the remote hostname.

Example:

git-cache-http-server --port 1234 --cache-dir /tmp/cache/git &
git clone http://localhost:1234/github.com/jonasmalacofilho/git-cache-http-server

If you run your git-cache on a dedicated server or container (i.e. named gitcache), you can then also configure git to always use your cache like in the following example (don't use this configuration on the git-cache machine itself):.

git config --global url."http://gitcache:1234/".insteadOf https:// && \

Installing

Requirements: nodejs and git.

Install: npm install -g git-cache-http-server

To install as a service, check the doc/git-cache-http-server.service example service file.

For Systemd init users, this file should not require major tweaks other than specifying a different than default port number or cache directory. After installed in the proper Systemd unit path for your distribution, issue:

systemctl daemon-reload
systemctl start git-cache-http-server

Building from source

This is needed only if you change the Haxe source code in src/.

Requirements: haxe and hmm. If you prefer to manage the build dependencies manually, check out hmm.json for the required libraries.

hmm install
haxe build.hxml

Implementation

The current implementation is somewhat oversimplified; any help in improving it is greatly appreciated!
