* py: Include mpconfig.h before all other includes.Paul Sokolovsky2014-06-21
| | | | | | It defines types used by all other headers. Fixes #691.

* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
* py, gc: Only zero out the extra bytes at the end of the heap chunk.Damien George2014-04-26
| | | | | This is a small optimisation to zero out only the additional bytes that the caller did not ask for.

* | py, gc: Zero out newly allocated blocks in the GC.Damien George2014-04-25
|/ | | | | | | | | | | | | | | | | | | | | | | | Also add some more debugging output to gc_dump_alloc_table(). Now that newly allocated heap is always zero'd, maybe we just make this a policy for the uPy API to keep it simple (ie any new implementation of memory allocation must zero all allocations). This follows the D language philosophy. Before this patch, a previously used memory block which had pointers in it may still retain those pointers if the new user of that block does not actually use the entire block. Eg, if I want 5 blocks worth of heap, I actually get 8 (round up to nearest 4). Then I never use the last 3, so they keep their old values, which may be pointers pointing to the heap, hence preventing GC. In rare (or maybe not that rare) cases, this leads to long, unintentional "linked lists" within the GC'd heap, filling it up completely. It's pretty rare, because you have to reuse exactly that memory which is part of this "linked list", and reuse it in just the right way. This should fix issue #522, and might have something to do with issue #510.

* py, gc: Further simplify coding-style of gc_realloc.Damien George2014-04-20
| | | | No logic changes, just coding style to make it easy to read.
* gc: "new" gc_realloc: Rewrite in plain C, fixing bunch of bugs.Paul Sokolovsky2014-04-20
| | | | | | There were typos, various rounding errors trying to do concurrent counting in bytes vs blocks, complex conditional paths, superfluous variables, etc., etc., all leading to obscure segfaults.

* Change object representation from 1 big union to individual structs.Damien2013-12-21
| | | | | | | | | | A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
