Prevent multiple uploads of the same file

main-- commented 9 years ago

Cases we're handling / need to handle:

[x] User drops the same file twice (simultaneously)
[x] User drops the same file twice (sequentially)
[ ] Two users drop the same file at the same time
[X] Anyone upload the same demo again after the analysis is finished

We actually don't need this I guess. Why should we? Parsing is cheap, demos are small. Non-issue.

Back then, parsing wasn't cheap, but fortunately we solved that one.

Still, the issue refers to functionality as well: Have we considered possible interactions between the two simultaneous analyses carefully? They'll probably overwrite each other's work all the time, but can this result in corrupt data? (And when we still saved the demo files, things were even funnier: We identified them by md5, but how would we handle two identical files?)

All of these are not necessarily failures or issues, just things we need to look at and keep in mind.
