Subject: [PATCH] [1.8.x] Simplified the lazy CSRF token implementation in csrf
context processor.
This significantly improves performance on PyPy. The previous
implementation would generate a new class on every single request,
which is relatively slow.
Backport of 8099d33b6553c9ee7de779ae9d191a1bf22adbda from master
