[Anthony Baxter] Hm. Would it be a smaller change to expose head_mutex so that the external module could use it? No, in part because `head_mutex` may not exist (depends on the build type). What an external module would actually need is 3 new public C API functions, callable workalikes for

[Python-Dev] Unary minus bug

2006-07-09 Thread Neil Schemenauer
The bug was reported by Armin in SF #1333982: the literal -2147483648 (i.e. the value of -sys.maxint-1) gives a long in 2.5, but an int in = 2.4. I have a fix but I wonder if it's the right thing to do. I suppose returning a long has the chance of breaking someone code. Here's the test

Just to make life harder ;-), I should note that code, docs and tests for sys._current_frames() are done, on the tim-current_frames branch. All tests pass, and there are no leaks in the new code. It's just a NEWS blurb away from being just another hectic release memory :-)
