Damien George 00137b8c11 py/map: Change hash-table allocation policy to be less aggressive.
Small hash tables (eg those used in user class instances that only have a
few members) now only use the minimum amount of memory necessary to hold
the key/value pairs.  This can reduce performance for instances that have
many members (because then there are many reallocations/rehashings of the
table), but helps to conserve memory.

See issue #1760.

Paul Sokolovsky 9b0714b24c py: Declare help, input, open builtins in core.
These are *defined* per-port, but why redeclare them again and again.

Damien George a649d72606 py/makeqstrdata: Add special case to handle \n qstr. 2016-04-14 15:22:36 +01:00
Damien George 2243d68345 py/makeqstrdata: Reinstate Python2 compatibility. 2016-04-14 14:37:04 +01:00
Damien George 49bb04ee64 py/makeqstrdata: Fix rendering of qstrs that have non-printable ASCII.
The qstr data needs to be turned into a proper C string so non-ASCII
chars must be properly escaped according to C rules.

Damien George 0c1de1cdee py: Simplify "and" action within parser by making ident-rules explicit.
Most grammar rules can optimise to the identity if they only have a single
argument, saving a lot of RAM building the parse tree.  Previous to this
patch, whether a given grammar rule could be optimised was defined (mostly
implicitly) by a complicated set of logic rules.  With this patch the
definition is always specified explicitly by using "and_ident" in the rule
definition in the grammar.  This simplifies the logic of the parser,
making it a bit smaller and faster.  RAM usage in unaffected.

Damien George f30b6f0af5 py/makeqstrdata: Add more names for escaped chars and esc non-printable.
Non-printable characters are escaped as 0xXX, where XX are the hex
digits of the character value.

Damien George 0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files.
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

Damien George 6d24dc23b8 py/emitglue: Move typedef of mp_raw_code_t from .c to .h file.
It's needed by frozen bytecode.

Damien George eacbd7aeba py: Fix constant folding and inline-asm to work with new async grammar. 2016-04-13 15:26:39 +01:00
pohmelie 81ebba7e02 py: add async/await/async for/async with syntax
They are sugar for marking function as generator, "yield from"
and pep492 python "semantically equivalents" respectively.

@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.

Damien George 657aef66ff py/stream: Simplify arg extraction logic for stream_ioctl.
Saves 16 bytes of code.

Also, use mp_obj_get_int_truncated to allow integers as big as a machine
word to be passed as the value.

Paul Sokolovsky 558fd5d228 py/stream: ioctl(): Properly support 2-arg form. 2016-04-10 13:36:44 +03:00

Paul Sokolovsky 0c97e4c414 py/stream: Add Python-level ioctl() method.
Will call underlying C virtual methods of stream interface. This isn't
intended to be added to every stream object (it's not in CPython), but
is convenient way to expose extra operation on Python side without
adding bunch of Python-level methods.

Damien George ce8b4e8749 py: Combine continuous block of emit steps into with_cleanup emit call.
Because different emitters need to handle with-cleanup in different ways.

Paul Sokolovsky e6a4d4e23c py: Move stream-related declarations from obj.h to stream.h. 2016-04-05 22:06:52 +03:00
Paul Sokolovsky 069654f2be py/obj.h: Add comment why mp_fun_kw_t takes non-const mp_map_t*.
mp_fun_kw_t takes mp_map_t* (and not const mp_map_t*) to ease passing
this arg to mp_map_lookup(), which may modify its arg, depending on
flags.

Paul Sokolovsky b1dfdaf6cb py/ringbuf.h: Add reusable ring buffer class.
Features inline get/put operations for the highest performance. Locking
is not part of implementation, operation should be wrapped with locking
externally as needed.

Damien George 2599672384 py/parsenum: Use pow function to apply exponent to decimal number.
Pow is already a dependency when compiling with floats, so may as well
use it here to reduce code size and speed up the conversion for most
cases.

Damien George e1e7657277 py/formatfloat: Fix further cases of buffer overflow in formatting.
Includes extensive test cases to catch hopefully all cases where
buffer might overflow.

Damien George 03b8bb7ec9 py/formatfloat: Fix case of float format where leading digit was "10".
When taking the logarithm of the float to determine the exponent, there
are some edge cases that finish the log loop too large.  Eg for an
input value of 1e32-epsilon, this is actually less than 1e32 from the
log-loop table and finishes as 10.0e31 when it should be 1.0e32.  It
is thus rendered as :e32 (: comes after 9 in ascii).

There was the same problem with numbers less than 1.

Paul Sokolovsky 24342dd65e extmod/modwebsocket: Start module for WebSocket helper functions.
Currently, only write support is implemented (of limited buffer size).
2016-03-24 19:16:00 +02:00
Paul Sokolovsky d4c8e626f2 py/stream: Add mp_stream_writeall() helper function.
Spools entire output buffer to a blocking stream (chunk by chunk if
needed).

Damien George 8d4d6731f5 py/parse: When looking up consts, check they exist before checking type. 2016-03-19 21:36:32 +00:00
Damien George 3acaa28b52 py: Don't allocate an extra parse node for power exponent.
Previous to this patch, the "**b" in "a**b" had its own parse node with
just one item (the "b").  Now, the "b" is just the last element of the
power parse-node.  This saves (a tiny bit of) RAM when compiling.
