py: Add option to compile without any error messages at all.

2021-04-27T13:51:52+00:00

This introduces a new option, MICROPY_ERROR_REPORTING_NONE, which
completely disables all error messages.  To be used in cases where
MicroPython needs to fit in very limited systems.

py/objexcept: Support errno attribute on OSError exceptions.

2021-04-23T12:03:46+00:00

This commit adds the errno attribute to exceptions, so code can retrieve
errno codes from an OSError using exc.errno.

The implementation here simply lets `errno` (and the existing `value`)
attributes work on any exception instance (they both alias args[0]).  This
is for efficiency and to keep code size down.  The pros and cons of this
are:

Pros:
- more compatible with CPython, less difference to document and learn
- OSError().errno will correctly return None, whereas the current way of
  doing it via OSError().args[0] will raise an IndexError
- it reduces code size on most bare-metal ports (because they already have
  the errno qstr)
- for Python code that uses exc.errno the generated bytecode is 2 bytes
  smaller and more efficient to execute (compared with exc.args[0]); so
  bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute,
  and bytecode that is frozen saves 2 bytes flash/ROM for each use
- it's easier/shorter to type, and saves 2 bytes of space in .py files that
  use it (for each use)

Cons:
- increases code size by 4-8 bytes on minimal ports that don't already have
  the `errno` qstr
- all exceptions now have .errno and .value attributes (a cpydiff test is
  added to address this)

py/runtime: Make sys.modules preallocate to a configurable size.

2021-04-12T12:36:16+00:00

This allows configuring the pre-allocated size of sys.modules dict, in
order to prevent unwanted reallocations at run-time (3 sys-modules is
really not quite enough for a larger project).

py/profile: Resolve name collision with STATIC unset.

2021-04-12T12:31:42+00:00

When building with STATIC undefined (e.g., -DSTATIC=), there are two
instances of mp_type_code that collide at link time: in profile.c and in
builtinevex.c.  This patch resolves the collision by renaming one of them.

rp2: Add support for USER_C_MODULES to CMake build system.

2021-03-30T13:26:01+00:00

The parts that are generic are added to py/ so they can be used by other
ports that use CMake.

py/usermod.cmake:

* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.

ports/rp2/CMakeLists.txt:

* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.

py/mkrules.cmake:

Add cxxflags to qstr.i.last custom command for CXX modules:

* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".

Usage:

The rp2 port can be linked against user C modules by running:

make USER_C_MODULES=/path/to/module/micropython.cmake

CMake will print a list of included modules.

py: Rename remaining object types to be of the form mp_type_xxx.

2021-03-26T02:48:34+00:00

For consistency with all other object types in the core.
