Molybdenum

A github tree viewer when your repo isn't on Github (or even if it is).

This is a node.js server that provides a web-browsable view of your git repos. Basically, you setup post-receive hooks for notifying Molybdenum of your repo pushes and that's it.

Currently basic repo browsing (somewhat Github-esque) is supported and integration with Jira for adding ticket comments for pushes referencing Jira tickets.

We're using this internally at Joyent.

WARNING: Unfortunately, right now I don't have bandwidth to support this well for others. I'm scratching a personal itch here, and a significant chunk of hacking and duct tape is involved. Also, this is significantly under-documented.

Overview

TODO

post-receive hook

To tell a Molybdenum server about a push to your git repo, you'll want to add something like this to your master git repo's "hooks/post-receive" file:

MOLYBDENUM_CREDENTIALS=user:pass
MOLYBDENUM_URL=https://molybdenum.example.com
echo "Pinging Molybdenum at ${MOLYBDENUM_URL} about push."
echo '{
    "repository": {
        "url": "git@code.example.com:cool-product.git",
        "name": "cool-product"
    }
}' | curl --connect-timeout 2 -Ss -k -u "${MOLYBDENUM_CREDENTIALS}" \
    "${MOLYBDENUM_URL}/api/repos" -H "Content-Type: application/json" \
    -X POST -d @- >/dev/null || echo "Error telling Molybdenum. Continuing anyway."

Note: Be sure to make "hooks/post-receive" executable (commonly overlooked).

If your repo is on github (even if private), you can use something like the following as a "Post-Receive URL" in "Service Hooks" panel of your repositories admin pages:

https://user:pass@molybdenum.example.com/api/repos

Obviously you need to adjust the URL and auth for whereever you are hosting Molybdenum.

Molybdenum post-fetch hooks

(TODO: this is slightly out of date. See the equiv section in docs/index.restdown.)

The "postFetchHooks" (global) config var is a comma-separate list of post-fetch hooks. These are either a hook name (for built-in hooks that ship with Molybdenum) or the full path to a separately installed post-fetch hook. For example:

postFetchHooks=jira,/home/mo/hooks/my-custom-post-fetch-hook

The built-in hooks are all at "tools/${NAME}-post-fetch-hook".

Each post-fetch hook is called for each branch/revision-range fetched whenever a repo is updated. They are called with the same signature as a regular git post-receive hook:

.../foo-post-fetch-hook OLDREV NEWREV REFNAME

with the addition that the "MOLYBDENUM_CONFIG" and "CONFIG" envvars are set to the full path to the Molybdenum json config file. This allows a post-fetch script to get configuration info. For example:

CONFIG=/home/mo/config/molybdenum.json \
    MOLYBDENUM_CONFIG=/home/mo/config/molybdenum.json \
    /home/mo/hooks/my-custom-post-fetch-hook ea8d8c5 8d83628 refs/heads/master

By convention a post-fetch hook needing config info should use a "${name}PostFetchHook" key in the json config file, E.g.:

...
"jiraPostFetchHook": {
    "moUrl": "https://mo.example.com",
    "jiraUrl": "https://jira.example.com/jira",
    "jiraCredentials": "somebody:somepassword",
    "jiraProjects": ["FOO", "BAR", "BAZ"],
    "branchWhitelist": ["*/master", "*/release-*", "special-repo/important-branch"],
    "branchBlacklist": []
}
...

Jira built-in post-fetch hook

This is a post-fetch hook to add a comment describing a commit to a Jira ticket if that ticket id (e.g. "PROJECTA-42") is mentioned in the commit message.
