Michael Bolin 0f4ba60602 Update the hg/post-clone hook to write the .hg/dirstate file. 
Summary:
Now that we make use of the `.hg/dirstate` file, we should ensure that it is
initialized correctly. This takes the commit hash from the `SNAPSHOT` file and
passes it as an argument to the `post-clone` hook. In the Hg `post-clone` hook,
it writes the `.hg/dirstate` file such that the first 20 bytes are the binary
version of the commit hash and the next 20 bytes are nul bytes.

Eden hooks

When Eden is deployed, the output of generate-hooks-dir should be installed in /etc/eden/hooks.

By default, Eden will look in /etc/eden/hooks for hooks. This can be overridden by specifying hooks in the [repository] section of an ~/.edenrc.

Note that hooks may require additional configuration. Hook authors should encourage users to specify such configuration in ~/.edenrc. This can be read from the hook via eden config.

The following files will be recognized in the hooks directory for the appropriate event:

post-clone

This will be run after eden clone. If the <repo_type> is .hg, the script is responsible for creating the .hg directory in the root of the Eden mount. It will receive the following arguments:

/etc/eden/hooks/hg/post-clone <repo_type> <eden_checkout> <repo>
  • <repo_type> is hg or git
  • <eden_checkout> is the path to the mounted Eden checkout.
  • <repo> is the path to the original Mercurial repository.
  • <hash> is the hex id of the initial commit
