* Scm.php: new SCM method "getChanges" which returns all available
change information grouped by type
* Monotone.php: implement getChanges via get_revision
* <other scms>: rename "changes" member for getCommit to "diff" which
matches better
* Source.php: query the commit's changes and set them in the template
* commit.html: render the changes, type-by-type. Link to the tree or
the individual diff if applicable
* styles.css: some initial style sheet work
Instead of returning a command which gets executed and which should
pass through / stream its output data to the client, we're just
returning an instance of Pluf_HTTP_Response. This is needed, because
some SCMs, most noticable monotone, have no locally executable command
to provide a snapshot archive (and probably never will for our kind
of setup).
We therefor added a little BSD-licensed class "ZipArchive" which allows
the creation of pkzip-compatible archives on the fly by letting it eat
the file contents directly feed from the (remote) stdio instance.
Download performance is ok and lies between 15K/s and 110K/s, but at
least we do no longer block the browser while we pre-generate the zip
file server-side.
Thanks to Patrick Georgi for all his work!
indentifiers in IDF - the SCM function isValidRevision has been replaced
by a validateRevision() method which returns one of three states,
valid, invalid or ambiguous.
The source view can then act accordingly and display disambiguate view
for the latter, so the user can select for which revision he actually
wants to execute the requested action. Also, invalid revisions now lead
to another separate view, telling the user that it is invalid / does
not exist and pointing him optionally to the help page where he can read
further how to access his repository to push the first changes into.
(partially resolves issue 525)
We now have a limited support of the code review. Still some work to be
done to allow the submission of new patches on a given review and update
the status. For the moment, only pre-commit review is supported.
This is because git will return an error code when testing if a commit
exists and in fact does not exist. So it means that we get an exception
on all the string "commit foo" when foo is not a commit in the issue
text.
