ec7fe92531 py/objarray: Split out header to allow direct access to object. 
This follows source code/header file organization similar to few other
objects, and intended to be used only is special cases, where efficiency/
simplicity matters.

426112ce88 extmod/moduos_dupterm: Reserve buffer bytearray object for dupterm. 
Allocating it for each read/write operation is a memory fragmentation
hazard.

737bd9c314 py/mpconfig.h: Mention MICROPY_PY_BTREE config option. 
However, as it requires linking with external libraries, it actually
should be ste on Makefile level.

ae184cb9de py/builtinimport: Disable "imported as namespace package" warning. 
Namespace packages are natural part of Python3, CPython3 doesn't have such
warning, it made sense only from point of view of Python2 legacy.

749cbaca7f py/gc: Calculate (and report) maximum contiguous free block size. 
Just as maximum allocated block size, it's reported in allocation units
(not bytes).

6a6e0b7e05 py/gc: Be sure to count last allocated block at heap end in stats. 
Previously, if there was chain of allocated blocks ending with the last
block of heap, it wasn't included in number of 1/2-block or max block
size stats.

94238d4ae5 py/nlrsetjmp: Update to take into account new location of nlr_top. 
It's now accessed via the MP_STATE_THREAD macro.

1df4168c33 py/nlrthumb: Convert NLR thumb funcs from asm to C with inline-asm. 
Now only the bits that really need to be written in assembler are written
in it, otherwise C is used.  This means that the assembler code no longer
needs to know about the global state structure which makes it much easier
to maintain.

df95f52583 py/modthread: Allow to properly set the stack limit of a thread. 
We rely on the port setting and adjusting the stack size so there is
enough room to recover from hitting the stack limit.

e90b6ce0b5 py/mpthread.h: Move GIL macros outside MICROPY_PY_THREAD block. 
The GIL macros are needed even if threading is not enabled.

a1c93a62b1 py: Don't use gc or qstr mutex when the GIL is enabled. 
There is no need since the GIL already makes gc and qstr operations
atomic.

4cec63a9db py: Implement a simple global interpreter lock. 
This makes the VM/runtime thread safe, at the cost of not being able to
run code in parallel.

3653f5144a py/gc: Fix GC+thread bug where ptr gets lost because it's not computed. 
GC_EXIT() can cause a pending thread (waiting on the mutex) to be
scheduled right away.  This other thread may trigger a garbage
collection.  If the pointer to the newly-allocated block (allocated by
the original thread) is not computed before the switch (so it's just left
as a block number) then the block will be wrongly reclaimed.

This patch makes sure the pointer is computed before allowing any thread
switch to occur.

c93d9caa8b py/gc: Make memory manager and garbage collector thread safe. 
By using a single, global mutex, all memory-related functions (alloc,
free, realloc, collect, etc) are made thread safe.  This means that only
one thread can be in such a function at any one time.

41167554e4 py/mphal.h: If virtpin API is used, automagically include its header. 2016-06-19 00:12:37 +03:00

413c3e10b4 py/objtype: instance: Inherit protocol vtable from a base class. 
This allows to define an  abstract base class which would translate
C-level protocol to Python method calls, and any subclass inheriting
from it will support this feature. This in particular actually enables
recently introduced machine.PinBase class.

3fecbb2462 extmod/machine_pinbase: Implementation of PinBase class. 
Allows to translate C-level pin API to Python-level pin API. In other
words, allows to implement a pin class and Python which will be usable
for efficient C-coded algorithms, like bitbanging SPI/I2C, time_pulse,
etc.

07209f8592 all: Rename mp_obj_type_t::stream_p to protocol. 
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.

f469c76442 py: Rename __QSTR_EXTRACT flag to NO_QSTR. 
It has more usages than just qstr extraction, for example, embedding (where
people don't care about efficient predefined qstrs).

dcb904416a py/makeqstrdefs.py: Remove restriction that source path can't be absolute. 
That's arbitrary restriction, in case of embedding, a source file path may
be absolute. For the purpose of filtering out system includes, checking
for ".c" suffix is enough.

b1533c4366 py/parse: Treat constants that start with underscore as private. 
Assignments of the form "_id = const(value)" are treated as private
(following a similar CPython convention) and code is no longer emitted
for the assignment to a global variable.

See issue #2111.

33168081f4 extmod/machine: Add MICROPY_PY_MACHINE_PULSE config for time_pulse_us.

functions.

751e3b7a82 extmod/virtpin: Initial implementation of open-ended C-level Pin interface. 
Using usual method of virtual method tables. Single virtual method,
ioctl, is defined currently for all operations. This universal and
extensible vtable-based method is also defined as a default MPHAL
GPIO implementation, but a specific port may override it with its
own implementation (e.g. close-ended, but very efficient, e.g. avoiding
virtual method dispatch).
