Age	Commit message (Collapse)	Author
2016-04-13	py: Add ability to have frozen persistent bytecode from .mpy files.	Damien George
	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).
2016-04-13	py/makeqstrdata: Factor out some code to functions that can be reused.	Damien George

2016-04-13	py/emitglue: Make mp_raw_code_t* arguments constant pointers.	Damien George

2016-04-13	py/emitglue: Move typedef of mp_raw_code_t from .c to .h file.	Damien George
	It's needed by frozen bytecode.
2016-04-13	py: Fix constant folding and inline-asm to work with new async grammar.	Damien George

2016-04-13	py: add async/await/async for/async with syntax	pohmelie
	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`.
2016-04-13	py/modbuiltins: __repl_print__: Add comment about setting "_" special var.	Paul Sokolovsky

2016-04-12	extmod/machine_i2c: Implement I2C memory reading/writing.	Damien George

2016-04-12	extmod: Add generic machine.I2C class, with bit-bang I2C.	Damien George
	Should work on any machine that provides the correct pin functions.
2016-04-12	extmod: Add initial framebuf module.	Damien George

2016-04-10	py/stream: Move uPy func obj wrappers to below their respective funcs.	Damien George

2016-04-10	py/stream: Simplify arg extraction logic for stream_ioctl.	Damien George
	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.
2016-04-10	py/stream: ioctl(): Properly support 2-arg form.	Paul Sokolovsky

2016-04-10	py/stream: Fix signed comparison issue.	Paul Sokolovsky

2016-04-10	py/stream: Add Python-level ioctl() method.	Paul Sokolovsky
	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.
2016-04-10	py/stream.h: Add bigger inventory of stream ioctl's.	Paul Sokolovsky

2016-04-07	py/objarray: Fix array.append so it doesn't extend if append fails.	Damien George
	Addresses issue #1965.
2016-04-07	py: Implement basic with support in native emitter.	Damien George

2016-04-07	py: Combine continuous block of emit steps into with_cleanup emit call.	Damien George
	Because different emitters need to handle with-cleanup in different ways.
2016-04-05	py: Move stream-related declarations from obj.h to stream.h.	Paul Sokolovsky

2016-04-04	py/obj.h: Add comment why mp_fun_kw_t takes non-const mp_map_t*.	Paul Sokolovsky
	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.
2016-04-01	py/map: Prevent map resize failure from destroying map.	Stephen Kyle

2016-03-30	py/ringbuf.h: Add reusable ring buffer class.	Paul Sokolovsky
	Features inline get/put operations for the highest performance. Locking is not part of implementation, operation should be wrapped with locking externally as needed.
2016-03-29	py/parsenum: Use pow function to apply exponent to decimal number.	Damien George
	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.
2016-03-29	py/formatfloat: Fix further cases of buffer overflow in formatting.	Damien George
	Includes extensive test cases to catch hopefully all cases where buffer might overflow.
2016-03-29	py/formatfloat: Fix case of float format where leading digit was "10".	Damien George
	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.
2016-03-27	py/stream: Fix stupid thinko with variable naming/shadowing.	Paul Sokolovsky

2016-03-25	extmod/modlwip: Add SOL_SOCKET and SO_REUSEADDR constants for setsockopt().	Paul Sokolovsky

2016-03-25	py/modio: io.BufferedWriter: Describe flushing policy.	Paul Sokolovsky

2016-03-25	py/modio: Implement io.BufferedWriter.flush().	Paul Sokolovsky

2016-03-25	py/modio: Initial implementation of io.BufferedWriter class.	Paul Sokolovsky
	Just .write() method implemented currently.
2016-03-24	py/stream: Fix object vs ptr usecase in mp_stream_writeall().	Paul Sokolovsky

2016-03-24	extmod/modwebsocket: Start module for WebSocket helper functions.	Paul Sokolovsky
	Currently, only write support is implemented (of limited buffer size).
2016-03-24	py/stream: Add mp_stream_writeall() helper function.	Paul Sokolovsky
	Spools entire output buffer to a blocking stream (chunk by chunk if needed).
2016-03-19	py/parse: When looking up consts, check they exist before checking type.	Damien George

2016-03-16	py: Don't allocate an extra parse node for power exponent.	Damien George
	Previous to this patch, the "b" in "ab" 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.
2016-03-16	py/frozenmod: Allow port to override lexer to use for frozen modules.	Paul Sokolovsky

2016-03-16	py/objfun: Allow inline-asm functions to be called with 4 arguments.	Damien George

2016-03-15	py/formatfloat: Fix buffer overflow when formatting tiny numbers.	Damien George

2016-03-15	py: For mp_buffer_info_t, change len type from mp_uint_t to size_t.	Damien George

2016-03-14	py/objarray: Fix array slice assignment when array is reallocated.	Damien George
	Addresses issue #1898.
2016-03-14	py/parsenum: Fix compiler warnings for no decl and signed comparison.	Damien George

2016-03-14	py: When printf'ing an object as a pointer, pass the concrete pointer.	Damien George

2016-03-14	py: Fix passing of some wide int types to printf varg format list.	Damien George
	Passing an mp_uint_t to a %d printf format is incorrect for builds where mp_uint_t is larger than word size (eg a nanboxing build). This patch adds some simple casting to int in these cases.
2016-03-14	py/argcheck: Use size_t instead of mp_uint_t to count number of args.	Damien George

2016-03-14	py/parsenum: Use size_t to count bytes, and int for type of base arg.	Damien George
	size_t is the proper type to count number of bytes in a string. The base argument does not need to be a full mp_uint_t, int is enough.
2016-03-10	py: Use MP_SMALL_INT_POSITIVE_MASK to check if uint fits in a small int.	Damien George
	Using the original WORD_MSBIT_HIGH-logic resulted in errors when the object model is not REPR_A or REPR_C.
2016-03-09	extmod/modlwip: Add dummy .makefile() method.	Paul Sokolovsky

2016-03-08	py/objboundmeth: Allocate arg state on stack if heap alloc fails.	Damien George
	If the heap is locked, or memory allocation fails, then calling a bound method will still succeed by allocating the argument state on the stack. The new code also allocates less stack than before if less than 4 arguments are passed. It's also a tiny bit smaller in code size. This was done as part of the ESA project.
2016-03-08	extmod/modlwip: Implement dummy setsockopt().	Paul Sokolovsky
