Root pointers are all located together to make GC tracing easier and more efficient. py: Move to guarded includes, everywhere in py/ core. 2015-01-01T20:32:09+00:00 Damien George damien.p.george@gmail.com 2015-01-01T20:27:54+00:00 urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde Addresses issue #1022. py: Fix function type: () -> (void). 2014-12-10T18:05:42+00:00 Damien George damien.p.george@gmail.com 2014-12-10T18:05:42+00:00 urn:sha1:b4fe6e28eb3bbf70b1f1da08a13a40a4ac3ee1db py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h. 2014-08-30T13:59:21+00:00 Damien George damien.p.george@gmail.com 2014-08-30T13:59:21+00:00 urn:sha1:4abff7500fb05430a2ce952a2430d4d0ba16047e Part of code cleanup, working towards resolving issue #50. stackctrl: Add "mp_" prefix. 2014-06-30T23:14:08+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-06-30T23:13:42+00:00 urn:sha1:caa7334141e6d67ab6f3064b250e6729095ae56c py: Add portable framework to query/check C stack usage. 2014-06-26T21:03:55+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-06-25T00:03:34+00:00 urn:sha1:23668698cba9bf861c697e65e3d07f9433396b8b Such mechanism is important to get stable Python functioning, because Python function calling is handled with C stack. The idea is to sprinkle STACK_CHECK() calls in places where there can be C recursion. TODO: Add more STACK_CHECK()'s.
