Damien George d1e355ea8e py: Fix check of small-int overflow when parsing ints.
Also unifies use of SMALL_INT_FITS macro across parser and runtime.

Damien George 5042bce8fb py: Don't automatically intern strings in parser.
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.

Paul Sokolovsky 9e76b1181b Draft approach towards resolving https://github.com/micropython/micropython/issues/560#issuecomment-42213955 2014-05-08 22:43:46 +03:00
Damien George 04b9147e15 Add license header to (almost) all files.
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/.

Damien George 58ba4c3b4c py: Check explicitly for memory allocation failure in parser.
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.

Paul Sokolovsky 56e5ef203b parse: Refactor parse node encoding to support full range of small ints.
Based on suggestion by @dpgeorge at

Paul Sokolovsky bbf0e2fe12 parse: Note that fact that parser's small ints are different than VM small int.
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().

Damien George c5966128c7 Implement proper exception type hierarchy.
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.

Damien George b829b5caec Implement mp_parse_node_free; print properly repr(string). 2014-01-25 13:51:19 +00:00
Paul Sokolovsky aee2ba70de Add parse_node_free_struct() and use it to free parse tree after compilation.
TODO: Check lexer/parse/compile error path for leaks too.

Damien George cbd2f7482c py: Add module/function/class name to exceptions.
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

Damien George 08335004cf Add source file name and line number to error messages.
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Damien George 9528cd66d7 Convert parse errors to exceptions.
Parser no longer prints an error, but instead returns an exception ID
and message.

Damien d99b05282d Change object representation from 1 big union to individual structs.
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).
