Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
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.

Damien George 99dde4ed1f qemu-arm: Enable GC and native code-gen; enable more tests. 2015-01-12 12:07:42 +00:00
Damien George 4a5895c4eb py: Disable stack checking by default; enable on most ports. 2015-01-09 00:10:55 +00:00
Damien George 85e8e2ed5b qemu-arm: Add 'test' target to Makefile to run and verify test suite.
Replaces RUN_TEST=1 definition; now "make test" in qemu-arm directory
will run tests/basics/ and check that they all succeed.

This patch also enables the test on Travis CI.

Paul Sokolovsky 46c3ab2004 modsys: Add sys.print_exception(exc, file=sys.stdout) function.
The function is modeled after traceback.print_exception(), but unbloated,
and put into existing module to save overhead on adding another module.
Compliant traceback.print_exception() is intended to be implemented in
micropython-lib in terms of sys.print_exception().

This change required refactoring mp_obj_print_exception() to take pfenv_t
interface arguments.

Addresses #751.

stijn 4e54c876a7 Add -Wpointer-arith flag to prevent problems with pointer arithmetic on void* 2014-10-29 10:29:09 +01:00
stijn 2fe4cf7761 Implement kwargs for builtin open() and _io.FileIO
This makes open() and _io.FileIO() more CPython compliant.
The mode kwarg is fully iplemented.
The encoding kwarg is allowed but not implemented; mainly to allow
the tests to specify encoding for CPython, see #874

Damien George a91ac2011f py: Make compiler return a proper exception on SyntaxError. 2014-10-05 19:01:34 +01:00
Damien George 52b5d76a6b py: Free non-interned strings in the parser when not needed.
mp_parse_node_free now frees the memory associated with non-interned
strings.  And the parser calls mp_parse_node_free when discarding a
non-used node (such as a doc string).

Also, the compiler now frees the parse tree explicitly just before it
exits (as opposed to relying on the caller to do this).

Addresses issue #708 as best we can.

Chris Dearman 8c56241c82 Declare do_str() function before the implementation
This ensures that GCC does not discard the do_str implementation in
some cases eg when compiling tests with debug enabled:
  make RUN_TESTS=1 DEBUG=1

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

Damien George 8dbbbbc793 Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.
qstr_init is always called exactly before mp_init, so makes sense to
just have mp_init call it.  Similarly with
mp_init_emergency_exception_buf.  Doing this makes the ports simpler and
less error prone (ie they can no longer forget to call these).

Ilya Dmitrichenko c1c32d65af qemu-arm: fully integrated test suite.
This is primarily intended to provide testing of Thumb-specific code within
Travis CI as well as if anyone else want to run it locally.  As discussed in
purposes.  This is currently agains an emulated Cortex-M3 core, however in
the near future it can extended to support M0, M0+ as well M4 (work in
progress exists in sushihangover/qemu).

It's probably true that most of the code base can be covered running uPy
natively on a POSIX system, however we do have the tiny bit of assembly
code.  There may exist bugs related to endianness and type aliases, let
alone potential standard library or compiler bugs or even
architecture-specific optimisations.

This could also incorporate lwIP (or other TCP/IP stack) integration as well
as SDIO+FATFS drivers.

The solution to inline the test cases was chose due to simplicity. It could
alternatively be implemented in a number of different way (see #515), but
this looked the simplest.

Inclusion of tinytest was just to avoid writing boilerplate code for
counting failed tests and other utility functions.  Currently only a few
functions are used, however this could be extended.  Checking in the code
instead of using submodule was a personal preference, but if people do want
the pain of submodules, this can provided.  This particular framework is
also pretty good if one desires to run unit test on target.  The approach
with scripts being inlined is probably not quite suited for the size of
memory an MCU has, but the tinytest itself should be good, if lower-level C
code is to be unit tested.
