* Fix two issues introduced by issue #71031 by changing the signature ofBrett Cannon2009-04-021-1/+1
| | | | PyImport_AppendInittab() to take a const char *.
* PyImport_AppendInittab() took a char * as a first argument even though thatBrett Cannon2009-04-021-1/+1
| | | | | | | string was stored beyond the life of the call. Changed the signature to be const char * to help make this point. Closes issue #1419652.
* Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} withJeffrey Yasskin2009-02-281-1/+3
| | | | | | POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing a POP_TOP on each conditional and sometimes allows the peephole optimizer to skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.

| | | | | | | http://mail.python.org/pipermail/python-dev/2008-June/079988.html Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names in the spirit of 3.0 are available via a #define only. See the email thread.

* Bug #1520864 (again): unpacking singleton tuples in list comprehensions andNeal Norwitz2006-09-051-1/+2
| | | | | | | | | | | | | generator expressions (x for x, in ... ) works again. Sigh, I only fixed for loops the first time, not list comps and genexprs too. I couldn't find any more unpacking cases where there is a similar bug lurking. This code should be refactored to eliminate the duplication. I'm sure the listcomp/genexpr code can be refactored. I'm not sure if the for loop can re-use any of the same code though. Will backport to 2.5 (the only place it matters).

* Bug #1191458: tracing over for loops now produces a line eventNeal Norwitz2006-08-041-1/+2
| | | | | | | | | | | | on each iteration. I'm not positive this is the best way to handle this. I'm also not sure that there aren't other cases where the lnotab is generated incorrectly. It would be great if people that use pdb or tracing could test heavily. Also: * Remove dead/duplicated code that wasn't used/necessary because we already handled the docstring prior to entering the loop. * add some debugging code into the compiler (#if 0'd out).
