      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: Implement core of OrderedDict type. · 0ef01d0a
      Paul Sokolovsky authored
      Given that there's already support for "fixed table" maps, which are
      essentially ordered maps, the implementation of OrderedDict just extends
      "fixed table" maps by adding an "is ordered" flag and add/remove
      operations, and reuses 95% of objdict code, just making methods tolerant
      to both dict and OrderedDict.
      Some things are missing so far, like CPython-compatible repr and comparison.
      OrderedDict is Disabled by default; enabled on unix and stmhal ports.

      objarray: Implement array slice assignment. · cefcbb22
      Paul Sokolovsky authored
      This is rarely used feature which takes enough code to implement, so is
      controlled by MICROPY_PY_ARRAY_SLICE_ASSIGN config setting, default off.
      But otherwise it may be useful, as allows to update arbitrary-sized data
      buffers in-place.
      Slice is yet to implement, and actually, slice assignment implemented in
      such a way that RHS of assignment should be array of the exact same item
      typecode as LHS. CPython has it more relaxed, where RHS can be any sequence
      of compatible types (e.g. it's possible to assign list of int's to a
      bytearray slice).
      Overall, when all "slice write" features are implemented, it may cost ~1KB
      of code.

      pyexec: Add event-driven variant pyexec_friendly_repl(). · 87bc8e2b
      Paul Sokolovsky authored
      pyexec_friendly_repl_process_char() and friends, useful for ports which
      integrate into existing cooperative multitasking system.
      Unlike readline() refactor before, this was implemented in less formal,
      trial&error process, minor functionality regressions are still known
      (like soft&hard reset support). So, original loop-based pyexec_friendly_repl()
      is left intact, specific implementation selectable by config setting.

      py: Add MICROPY_QSTR_BYTES_IN_LEN config option, defaulting to 1. · 95836f84
      Damien George authored
      This new config option sets how many fixed-number-of-bytes to use to
      store the length of each qstr.  Previously this was hard coded to 2,
      but, as per issue #1056, this is considered overkill since no-one
      needs identifiers longer than 255 bytes.
      With this patch the number of bytes for the length is configurable, and
      defaults to 1 byte.  The configuration option filters through to the
      makeqstrdata.py script.
      Code size savings going from 2 to 1 byte:
      - unix x64 down by 592 bytes
      - stmhal down by 1148 bytes
      - bare-arm down by 284 bytes
      Also has RAM savings, and will be slightly more efficient in execution.

      py: Add option to cache map lookup results in bytecode. · 7ee91cf8
      Damien George authored
      This is a simple optimisation inspired by JITing technology: we cache in
      the bytecode (using 1 byte) the offset of the last successful lookup in
      a map. This allows us next time round to check in that location in the
      hash table (mp_map_t) for the desired entry, and if it's there use that
      entry straight away.  Otherwise fallback to a normal map lookup.
      Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.
      On a few tests it gives >90% cache hit and greatly improves speed of
      Disabled by default.  Enabled for unix and stmhal ports.

      py: Put all global state together in state structures. · b4b10fd3
      Damien George authored
      This patch consolidates all global variables in py/ core into one place,
      in a global structure.  Root pointers are all located together to make
      GC tracing easier and more efficient.

      py: Allow builtins to be overridden. · 78d702c3
      Damien George authored
      This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
      which, when enabled, allows to override all names within the builtins
      module.  A builtins override dict is created the first time the user
      assigns to a name in the builtins model, and then that dict is searched
      first on subsequent lookups.  Note that this implementation doesn't
      allow deleting of names.
      This patch also does some refactoring of builtins code, creating the
      modbuiltins.c file.
      Addresses issue #959.
