Forwarding actual permissions to Mercurial processes
Closes #334 (closed)
Normally, the abstraction layers in GitLab mean that the Project
should not be accessible from the low level repository. However,
we need it to pass it down to the hg
processes. Doing it in
hg_env_for_write
is the way to make it really robust, since all
write operations basically have to use it.
To mitigate somewhat this breach of abstraction, we make the
attribute writable only, and we give it a more specific name than
just '@project'. Aesthetically, it would be better to store only
a factory for the UserAccess
instance that we really need, but
that could be done separately.
