Fixes #1814 Check that a never free pointer is on the heap. 2019-04-09T22:12:28+00:00 Scott Shawcroft scott@tannewt.org 2019-04-09T22:12:28+00:00 urn:sha1:ee7a77db65f24b3e34a9b9b733887cab3434d225 This fixes a crash on boards with built-in displays which statically allocate the display bus. When the pointer is provided to never free, it tries to allocate on the non-existant heap and crashes. Reorganize board busses into shared-bindings and shared-module. 2019-04-08T23:58:50+00:00 Scott Shawcroft scott@tannewt.org 2019-04-08T23:58:50+00:00 urn:sha1:0f003ac5b8312fafb120e86e05eefd2431014d8c Fix function signature 2019-03-12T21:05:31+00:00 Scott Shawcroft scott@tannewt.org 2019-03-12T21:05:31+00:00 urn:sha1:911509c80c0767bed81a4a3757c7691af9be19ea Enter safe mode when an allocation is attempted on an uninitialized heap. 2019-03-12T18:18:26+00:00 Scott Shawcroft scott@tannewt.org 2019-03-08T23:29:14+00:00 urn:sha1:03be42ab847f04a89d207d98fdb28048cfedf72d WIP: after merge; before testing 2018-07-11T20:45:30+00:00 Dan Halbert halbert@halwitz.org 2018-07-11T20:45:30+00:00 urn:sha1:7c219600a246d8956d0b23ea3f5d125a820e6b6a Analysis fixes and long lived tweaks. 2018-07-03T12:45:50+00:00 Scott Shawcroft scott@tannewt.org 2018-06-27T18:17:13+00:00 urn:sha1:252aacdddf1aae89e3ebe91ca72a3ad666728e37 py/gc: Add gc_sweep_all() function to run all remaining finalisers. 2018-06-12T01:55:29+00:00 Damien George damien.p.george@gmail.com 2018-05-31T13:10:48+00:00 urn:sha1:522ea80f06a80fd799bd57de351373ceaeeae325 This patch adds the gc_sweep_all() function which does a garbage collection without tracing any root pointers, so frees all the memory, and most importantly runs any remaining finalisers. This helps primarily for soft reset: it will close any open files, any open sockets, and help to get the system back to a clean state upon soft reset. py/gc: When GC threshold is hit don't unnecessarily collect twice. 2018-05-21T03:36:21+00:00 Damien George damien.p.george@gmail.com 2018-05-21T03:36:21+00:00 urn:sha1:6bd78741c13849da0570710ad6df80846df812c0 Without this, if GC threshold is hit and there is not enough memory left to satisfy the request, gc_collect() will run a second time and the search for memory will happen again and will fail again. Thanks to @adritium for pointing out this issue, see #3786.
