Comment 2 Jindrich Sedek 2009-08-04 08:38:46 UTC 
I found that one of sql files was a DB dump of about 500MB, not sure what we can do about such situation, but some 
warning or skipping the file in diff would be probably better than block AWT for such a long time.
Comment 3 Jiri Skrivanek 2009-09-17 11:53:52 UTC 
It is a general problem of diff module. You can reproduce it even with plain text 500 MB file.
Comment 4 Ondrej Vrabec 2009-09-21 12:38:50 UTC 
I guess we could show a warning dialog when trying to diff a too big file with possibility to skip diffing such file.
But not in 6.8 (it's not a trivial change, it involves not only diff module but also all versioning systems, where the
file could also be opened). Planning for the next release.
