      lib/utils/pyexec: Condition-out GC calls from pyexec. · 8aa3cbf1
      Colin Hogben authored
      A port which uses lib/utils/pyexec.c but which does not enable garbage
      collection should not need to implement the gc_collect function.
      
      This patch also moves the gc_collect call to after printing the qstr
      info.  Since qstrs cannot be collected it should not make any difference
      to the printed statistics.

      py: Overhaul and simplify printf/pfenv mechanism. · 7f9d1d6a
      Damien George authored
      Previous to this patch the printing mechanism was a bit of a tangled
      mess.  This patch attempts to consolidate printing into one interface.
      
      All (non-debug) printing now uses the mp_print* family of functions,
      mainly mp_printf.  All these functions take an mp_print_t structure as
      their first argument, and this structure defines the printing backend
      through the "print_strn" function of said structure.
      
      Printing from the uPy core can reach the platform-defined print code via
      two paths: either through mp_sys_stdout_obj (defined pert port) in
      conjunction with mp_stream_write; or through the mp_plat_print structure
      which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
      on the platform.  The former is only used when MICROPY_PY_IO is defined.
      
      With this new scheme printing is generally more efficient (less layers
      to go through, less arguments to pass), and, given an mp_print_t*
      structure, one can call mp_print_str for efficiency instead of
      mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
      Thumb2 archs.

      py: Protect mp_parse and mp_compile with nlr push/pop block. · 0bfc7638
      Damien George authored
      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.

      modsys: Add sys.print_exception(exc, file=sys.stdout) function. · 46c3ab20
      Paul Sokolovsky authored
      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.

      py: Optimise lexer by exposing lexer type. · a4c52c5a
      Damien George authored
      mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer
      functions (like checking current token kind) are now inlined.
      
      This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460
      bytes on bare-arm.  It also saves a tiny bit of RAM since mp_lexer_t
      is a bit smaller.  Also will run a bit more efficiently.

      Implement kwargs for builtin open() and _io.FileIO · 2fe4cf77
      stijn authored
      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

      py: Free non-interned strings in the parser when not needed. · 52b5d76a
      Damien George authored
      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.
