When a user is not authorized to see the list of hooks for a project, he is
still able to access the hooks separately. For example if access to
`GET /projects/:id/hooks` fails and returns a `403 Unauthorized` error it is
still possible to access a hook directly via `GET /projects/:id/hooks/:hook_id`.
Fixes access, also added tests to check access and status codes of hooks.
This option allows to disable users from changing their username.
This is very usefull in environments using strong internal authentication methods like ldap, pam or shibboleth.
You can allow users to change theyr username in these environments, but then new users (users loging in first time) is blocked from gitlab is her username exists.
The previous call `saved?` is restored in the `POST /projects` method in the API.
It is refactored to check if the record is persisted. This is useful to not validate
the record again after saving. This fixes the returned status code in the web client
too. If the last project is created via web client instead of error notification
the project page is shown.
When creating the last project via API when reaching the project limit a status code
of 404 (Not found) is returned instead of 201 (Created). The fix checks now correctly if
the project could be saved.
When reaching the project limit the API returns an error code 404 on the last possible
project. The project itself is created and is available in the database (seems valid).
A similar behavior can be observed when reaching the project limit via web client, but
in this case the user is notified that the maximum number of projects is reached. The project
itself is still created and can be accessed.
Tests are added to check the behavior when reaching the project limit or one tries
to exceed it via the API.
Mac OS uses launchd instead of /etc/init.d to start daemons and tasks to be started by launchd MUST NOT daemon itself. So "nohup" here won't work for Mac OS.
Can we add a "launchd" task to the rake file so that we can start sidekiq as "bundle exec rake sidekiq:launchd" ?
