This is quite useful if tests only need the database and not the whole app.
Then only this fixture is needed instead of the full blown pylonsapp/app fixtures.
Based on my original research, this was the "minimal" starting point. It shows
that three concepts are needed for the "repo_name":
* From the security standpoint we think of the shadow repository having the same
ACL as the target repository of the pull request. This is because the pull
request itself is considered to be a part of the target repository.
Out of this thought, the variable "acl_repo_name" is used whenever we want to
check permissions or when we need the database configuration of the
repository. An alternative name would have been "db_repo_name", but the usage
for ACL checking is the most important one.
* From the web interaction perspective, we need the URL which was originally
used to get to the repository. This is because based on this base URL commands
can be identified. Especially for Git this is important, so that the commands
are correctly recognized.
Since the URL is in the focus, this is called "url_repo_name".
* Finally we have to deal with the repository on the file system. This is what
the VCS layer deal with normally, so this name is called "vcs_repo_name".
The original repository interaction is a special case where all three names are
the same.
When interacting with a pull request, these three names are typically all
different.
This change is minimal in a sense that it just makes the interaction with a
shadow repository barely work, without checking any special constraints yet.
This was the starting point for further work on this topic.
This custom header sets the SCM backend which is in use. It is used to identify
VCS responses in the error handler. VCS responses are skipped during error handling.
Ensuring now that we always disable the vcsserver auto start for the test suite,
since the test suite bootstraps its own vcsserver process.
Also enhanced TestINI.
It currently resembles the logic from the old markup renderer. The
implementation is based on get_nodes though, so that we should usually only have
one call or at most three calls if the directories "doc" and/or "docs" exist.
A difference is that we now ignore the case, this already simplifies the rule
definition.
