The mapping between bytecode offsets and source lines (lnotab) did not contain an entry for the beginning of the loop. Now it does, and the lnotab can be a bit larger: in particular, several statements on the same line generate several entries. However, this does not bother the settrace function, which will trigger only one 'line' event. The lnotab seems to be exactly the same as with python2.4. ........ r60584 | amaury.forgeotdarc | 2008-02-05 01:26:21 +0100 (Tue, 05 Feb 2008) | 3 lines Change r60575 broke test_compile: there is no need to emit co_lnotab item when both offsets are zeros. ........ r60587 | skip.montanaro | 2008-02-05 03:32:16 +0100 (Tue, 05 Feb 2008) | 1 line sync with most recent version from python-mode sf project ........ r60588 | lars.gustaebel | 2008-02-05 12:51:40 +0100 (Tue, 05 Feb 2008) | 5 lines Issue #2004: Use mode 0700 for temporary directories and default permissions for missing directories.

All free lists in Object/ are named ``free_list``, the counter ``numfree`` and the upper limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
