* py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.Damien George2015-10-02
| | | | | | | | With this patch parse nodes are allocated sequentially in chunks. This reduces fragmentation of the heap and prevents waste at the end of individually allocated parse nodes. Saves roughly 20% of RAM during parse stage.
* py: Expose compile.c:list_get as mp_parse_node_extract_list.Damien George2015-02-13

* py: Parse big-int/float/imag constants directly in parser.Damien George2015-02-08
| | | | | | | | | Previous to this patch, a big-int, float or imag constant was interned (made into a qstr) and then parsed at runtime to create an object each time it was needed. This is wasteful in RAM and not efficient. Now, these constants are parsed straight away in the parser and turned into objects. This allows constants with large numbers of digits (so addresses issue #1103) and takes us a step closer to #722.
* py: Protect mp_parse and mp_compile with nlr push/pop block.Damien George2015-02-07
| | | | | | | | | | To enable parsing constants more efficiently, mp_parse should be allowed to raise an exception, and mp_compile can already raise a MemoryError. So these functions need to be protected by an nlr push/pop block. This patch adds that feature in all places. This allows to simplify how mp_parse and mp_compile are called: they now raise an exception if they have an error and so explicit checking is not needed anymore.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01

* py: Convert [u]int to mp_[u]int_t where appropriate.Damien George2014-10-03
| | | | Addressing issue #50.

* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* py: Fix check of small-int overflow when parsing ints.Damien George2014-05-28
| | | | Also unifies use of SMALL_INT_FITS macro across parser and runtime.
* py: Don't automatically intern strings in parser.Damien George2014-05-25
| | | | | | | | This completes non-automatic interning of strings in the parser, so that doc strings don't take up RAM. It complicates the parser and compiler, and bloats stmhal by about 300 bytes. It's complicated because now there are 2 kinds of parse-nodes that can be strings: interned leaves and non-interned structs.

* 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: Check explicitly for memory allocation failure in parser.Damien George2014-04-10
| | | | | | Previously, a failed malloc/realloc would throw an exception, which was not caught. I think it's better to keep the parser free from NLR (exception throwing), hence this patch.

* parse: Refactor parse node encoding to support full range of small ints.Paul Sokolovsky2014-02-22
| | | | | Based on suggestion by @dpgeorge at https://github.com/micropython/micropython/pull/313
* parse: Note that fact that parser's small ints are different than VM small int.Paul Sokolovsky2014-02-21
| | | | | | Specifically, VM's small ints are 31 bit, while parser's only 28. There's already MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to MP_PARSE_FITS_SMALL_INT().
* Implement proper exception type hierarchy.Damien George2014-02-15
| | | | | | | | | | | | | | Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency.

* Add parse_node_free_struct() and use it to free parse tree after compilation.Paul Sokolovsky2014-01-25
| | | | TODO: Check lexer/parse/compile error path for leaks too.
* py: Add module/function/class name to exceptions.Damien George2014-01-19
| | | | | | | Exceptions know source file, line and block name. Also tidy up some debug printing functions and provide a global flag to enable/disable them.
* Add source file name and line number to error messages.Damien George2014-01-18
| | | | | Byte code has a map from byte-code offset to source-code line number, used to give better error messages.
* Convert parse errors to exceptions.Damien George2014-01-15
| | | | | Parser no longer prints an error, but instead returns an exception ID and message.
* 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).
