      py: Don't automatically intern strings in parser. · 5042bce8
      Damien George authored
      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.

      py: Improve handling of memory error in parser. · 1b82e9af
      Damien George authored
      Parser shouldn't raise exceptions, so needs to check when memory
      allocation fails.  This patch does that for the initial set up of the
      parser state.
      Also, we now put the parser object on the stack.  It's small enough to
      go there instead of on the heap.
      This partially addresses issue #558.

      py: Turn down amount of RAM parser and compiler use. · 66e18f04
      Damien George authored
      There are 2 locations in parser, and 1 in compiler, where memory
      allocation is not precise.  In the parser it's the rule stack and result
      stack, in the compiler it's the array for the identifiers in the current
      scope.  All other mallocs are exact (ie they don't allocate more than is
      This patch adds tuning options (MP_ALLOC_*) to mpconfig.h for these 3
      inexact allocations.
      The inexact allocations in the parser should actually be close to
      logarithmic: you need an exponentially larger script (absent pathological
      cases) to use up more room on the rule and result stacks.  As such, the
      default allocation policy for these is now to start with a modest sized
      stack, but grow only in small increments.
      For the identifier arrays in the compiler, these now start out quite
      small (4 entries, since most functions don't have that many ids), and
      grow incrementally by 6 (since if you have more ids than 4, you probably
      have quite a few more, but it wouldn't be exponentially more).
      Partially addresses issue #560.

      Add license header to (almost) all files. · 04b9147e
      Damien George authored
      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 authored
      Implement not, shl and shr in mpz library.  Add function to create mpzs
      on the stack, used for memory efficiency when rhs is a small int.
      Factor out code to parse base-prefix of number into a dedicated function.

      Implement proper exception type hierarchy. · c5966128
      Damien George authored
      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.

      Change object representation from 1 big union to individual structs. · d99b0528
      Damien authored
      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
      Also change name prefix, from py_ to mp_ (mp for Micro Python).
