Okay, not exactly. What it really does is pass in details of any commits made as soon as it's notified about them -
how and when it gets notified is flexible, though it was primarily built to be triggered by a
post-receive git hook;
e.g. when someone performs a
git push. You can use it as a
post-commit hook if you like, or however you want (your
mileage may vary).
How It Works
Pretty crudely at the moment. Your post-receive hook (or other, whatever's most suitable) invokes your node server and passes it information about any updated commit references, which in turn updates a local git repo, gets the log details for the input revision references and then writes the output to stdout, which is piped into gource's stdin. Gource itself takes care of everything else - all goursome does is provide a way of getting it new data in a manner which lends itself well to simplistic remote invocation (e.g. over http).
Make sure you've got node (>= 0.4.0), gource (>= 0.35) and
on your machine(s) you wish to run goursome on. You'll need the
node_redis driver too.
1) Clone this repository to wherever you choose
This will start an instance of the HTTP server which is responsible for listening to incoming notifications before publishing them to a Redis channel.
./goursome.js /path/to/local/git/repo/ project_name | gource --log-format git -i 0 --key -
You can now invoke as many instances of goursome as you want project visualisations for.
4) On a remote, slap this in your
post-receive, and make sure it has execute permissions:
#!/bin/bash read oldrev newrev refname curl -d "oldrev=$oldrev&newrev=$newrev&refname=$refname&namespace=project_name" http://your-server-address:2424/ > /dev/null 2>&1
5) You're done!
The primary use case is to have a permanent, up-to-date visualisation of a project's source tree on show in a team environment. Given the distributed nature of git, goursome will work best as a post-receive hook on a remote repository which everyone in the team pushes to - e.g. in the most svn-esque use case where everyone in the team pushes to a main remote.
Plenty of them:
each visualisation is bound to a single HTTP server - can't run more than one per machine without altering port bindings (easily solved)
- visualised repository must be on the local filesystem - this was a design decision but can't remember why now. Far less HTTP traffic involved in just sending commit refs rather than log messages was definitely one concern
- visualised repository must be able to perform a
git pullwithout interaction (e.g. no password or passphrase prompt)
- no concept of branches - post-receive will always trigger, so it's master or bust for now
- error intolerant - if something goes wrong, goursome won't really tell you, and bad things will probably happen
- namespace stuff is a bit rubbish -
it was just a quick fix to stop multiple post-receive hooks tieing the server process in knots firing commit hashes at it it knew nothing about (as it's always bound to just one repository for now)
