Author Commented: (MODPYTHON-48) psp.PSP doesn't work for a text string

dharana commented on MODPYTHON-48:
----------------------------------

Attached psp.diff has bad indentation in this part:

! source = _psp.parsestring(string)
! code = compile(source, "__psp__", "exec")
! mem_scache.store(string,code)
! self.code = code


It should be

! source = _psp.parsestring(string)
! code = compile(source, "__psp__", "exec")
! mem_scache.store(string,code)
! self.code = code

Aside from that, from the fact that the diff mentions 3.1.3 instead of 3.1.4 and aside from the missing header warning it correctly and definitely fixes the bug. Confirmed here.

I've attached graham's patch with the indent typos and the 3.1.4 fixed. Hope it's ok.
