New issue 3370 by [email protected]: condense diffs function runs out
of memory on larger installs
http://code.google.com/p/reviewboard/issues/detail?id=3370
What version are you running?
2.0
What's the URL of the page containing the problem?
N/A
What steps will reproduce the problem?
1. Running "rb-site manage /var/www/codereview condensediffs"
What is the expected output? What do you see instead?
The operation fails with a MemoryError:
rb-site manage /var/www/codereview condensediffs
Processing 152829 diffs for duplicates...
This may take a while. It is safe to continue using Review Board while this
is
processing, but it may temporarily run slower.
