* Repo collab now supports basic default roles developer/user/guest like
project collab does
* User/Anon collab for repos and projects are now stored as fields instead of
in dedicated tables, there was never a need for dedicated tables but I didn't
see that before
* Repo push op is now part of `ProjectOperation`
* `RepoRole` and related code has been entirely removed, only project roles
remain and they're used for both repos and projects
* This is the first not-totally-trivial DB migration in Vervis, it's automatic
but please be careful and report errors
I used this chance to make some name changes, add some utils, tweak some
imports, remove more `setTitle`s and so on. I also made person, repo,
key and project creation forms verify CI-uniqueness.
I decided to add some safety to routes:
- Use dedicated newtypes
- Use CI for the CI-unique DB fields
Since such a change requires so many changes in many source files, this
is also a chance to do other such breaking changes. I'm recording the
change gradually. It won't build until I finish, so for now don't waste
time trying to build the app.
Darcs does export most of its module tree, but there's a problem: Darcs
relies on the current directory. It changes the current directory of the
process to the repo, and then proceeds using paths relative to the repo
dir. This is bad for my case here. If some other thread uses a relative
path (e.g. currently any repo path is relative by default) in parallel,
it will fail.
For now, the quick path around this problem is to use the `darcs`
program.
At the beginning the rendering was invalid because it parsed the entire
content as a single line. For some reason, when I read the ticket
description from the DB, all newlines are returned as CRLF. I don't know
why yet or whether it can or should be changed, but as a quick fix, I
made the handler function filter out the CRs from the text. Then the
rendering is correct.
This matches the documentation of Pandoc, which mentions the readers
assume newlines are encoded as LF.
