[vmchecker-dev] storing submissions

[Alexandru Moșoi]

I've been working on the new storing-in-git schema, but I have the
following problems:
* how do I get a transaction? what if a homework is submitted very fast?
* how do I retrieve old submissions? how do I browse old submissions?
I can manually revert to the last submission, but automatically
retrieving an arbitrary past submission is close to impossible.


Now I have two solutions:
1) use MySQL + BLOBs
2) go back to the traditional way: store each submission to it's own directory.

Personally, I prefer the second solution because I don't trust databases :).
Any third solution? Other remarks?
