Damien George e33806aaff py/gc: Fix 2 cases of concurrent access to ATB and FTB. 2016-06-28 11:28:49 +01:00
Damien George 7f4658a7ee py/modthread: Satisfy unused-args warning. 2016-06-28 11:28:49 +01:00
Damien George 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.

Damien George 330165a2cc py: Add MP_STATE_THREAD to hold state specific to a given thread. 2016-06-28 11:09:31 +01:00
Paul Sokolovsky c7fba524cb py/objtype: Inherit protocol vtable from base class only if it exists. 2016-06-19 00:56:06 +03:00
Paul Sokolovsky 41167554e4 py/mphal.h: If virtpin API is used, automagically include its header. 2016-06-19 00:12:37 +03:00
Paul Sokolovsky 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.
2016-06-19 00:01:59 +03:00
Paul Sokolovsky 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.

Paul Sokolovsky 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.
2016-06-18 18:44:57 +03:00
Paul Sokolovsky 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).
2016-06-16 01:42:48 +03:00
Paul Sokolovsky 230d5cda05 py/mkrules.mk: Define "lib" outside conditional block.
"lib" happened to be defined inside block conditional on $(PROG).
2016-06-16 01:11:24 +03:00
Paul Sokolovsky 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.
2016-06-16 01:04:42 +03:00
Paul Sokolovsky 0f5bf1aafe py/mpconfig.h: MP_NOINLINE is universally useful, move from unix port. 2016-06-15 23:52:00 +03:00
Paul Sokolovsky 337111ba9e py: Support to build berkeley db 1.85 and "btree" module. 2016-06-15 00:52:45 +03:00
Mark Anthony Palomer 3131053e1a py/objdict: Implemented OrderedDict equality check. 2016-06-12 17:33:48 +03:00
Damien George 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.

Damien George 33168081f4 extmod/machine: Add MICROPY_PY_MACHINE_PULSE config for time_pulse_us.
Since not all ports that enable the machine module have the pin HAL
functions.
2016-05-31 14:25:19 +01:00
Damien George 4940bee62a extmod: Add machine time_pulse_us function (at C and Python level).
The C implementation is taken from the DHT driver.
2016-05-31 13:58:48 +01:00
Damien George 715ee9d925 py/modstruct: Allow to have "0s" in struct format. 2016-05-28 23:27:38 +01:00
Paul Sokolovsky 2ec0ee082a py/moduerrno: Add ECONNREFUSED, one of frequent networking errors. 2016-05-28 00:17:19 +03:00
Paul Sokolovsky 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).
2016-05-27 01:08:43 +03:00
Paul Sokolovsky c76acd8c23 py/moduerrno: Add EEXIST, EISDIR.
Useful to check file/dir operations result, in particular used by upip.
2016-05-25 01:23:57 +03:00
Antonin ENFRUN ca41dc2750 py/objnamedtuple: Allow passing field names as a tuple.
So the documentation's example works.  Besides, a tuple can be more
memory efficient.
2016-05-23 21:08:07 +01:00
Damien George 202d5acd06 py/makeqstrdata.py: Allow to have double-quote characters in qstrs.
When rendering the qstr for a C header file, the double-quate character
must be escaped.
2016-05-23 15:18:55 +01:00
Damien George 274952a117 py: Allow to stat and import frozen mpy files using new frozen "VFS".
Freezing mpy files using mpy-tool.py now works again.

Paul Sokolovsky 9dde6062cc py/objstr: Fix mix-signed comparison in str.center(). 2016-05-22 02:22:14 +03:00
Dave Hylands 6a60fb3cf4 py/objstr*: Properly ifdef str.center(). 2016-05-22 01:54:41 +03:00
Paul Sokolovsky 1b5abfcaae py/objstr: Implement str.center().
Disabled by default, enabled in unix port. Need for this method easily
pops up when working with text UI/reporting, and coding workalike
manually again and again counter-productive.

Paul Sokolovsky 2c573f00b8 py/builtinimport: Unbreak bare-arm build. 2016-05-21 22:37:58 +03:00
Paul Sokolovsky 8a2970e136 py/builtinimport: Unbreak minimal build.
These are workarounds required until frozen .mpy loading following standard
frozen modules code path.
2016-05-21 22:23:08 +03:00
Paul Sokolovsky fb742cdc12 py/{builtinimport,frozenmod}: Rework frozen modules support to support packages.
Now frozen modules is treated just as a kind of VFS, and all operations
performed on it correspond to operations on normal filesystem. This allows
to support packages properly, and potentially also data files.

This change also have changes to rework frozen bytecode modules support to
use the same framework, but it's not finished (and actually may not work,
as older adhox handling of any type of frozen modules is removed).

Paul Sokolovsky 5a2a4e9452 py/mphal.h: Provide default prototypes for mp_hal_delay_us/mp_hal_ticks_us.
Similar to existing mp_hal_delay_ms/mp_hal_ticks_ms.
2016-05-21 02:13:50 +03:00
Paul Sokolovsky 497660fcda py/stream: Add mp_stream_close() helper function. 2016-05-20 21:18:49 +03:00
Damien George 3ff16ff52e py: Declare constant data as properly constant.
Otherwise some compilers (eg without optimisation) will put this read-only
data in RAM instead of ROM.
2016-05-20 12:46:20 +01:00
Paul Sokolovsky 7f7c84b10a py/stream: Support both "exact size" and "one underlying call" operations.
Both read and write operations support variants where either a) a single
call is made to the undelying stream implementation and returned buffer
length may be less than requested, or b) calls are repeated until requested
amount of data is collected, shorter amount is returned only in case of
EOF or error.

These operations are available from the level of C support functions to be
used by other C modules to implementations of Python methods to be used in
user-facing objects.

The rationale of these changes is to allow to write concise and robust
code to work with *blocking* streams of types prone to short reads, like
serial interfaces and sockets. Particular object types may select "exact"
vs "once" types of methods depending on their needs. E.g., for sockets,
revc() and send() methods continue to be "once", while read() and write()
thus converted to "exactly" versions.

These changes don't affect non-blocking handling, e.g. trying "exact"
method on the non-blocking socket will return as much data as available
without blocking. No data available is continued to be signaled as None
return value to read() and write().

From the point of view of CPython compatibility, this model is a cross
between its io.RawIOBase and io.BufferedIOBase abstract classes. For
blocking streams, it works as io.BufferedIOBase model (guaranteeing
lack of short reads/writes), while for non-blocking - as io.RawIOBase,
returning None in case of lack of data (instead of raising expensive
exception, as required by io.BufferedIOBase). Such a cross-behavior
should be optimal for MicroPython needs.

Paul Sokolovsky 2ae6697300 py/objstringio: Add TODO comment about avoiding copying on .getvalue(). 2016-05-14 14:46:13 +03:00
Damien George cc80c4dd59 py/objstr: Make dedicated splitlines function, supporting diff newlines.
It now supports \n, \r and \r\n as newline separators.

Adds 56 bytes to stmhal and 80 bytes to unix x86-64.

Fixes issue #1689.

Paul Sokolovsky 68a7a92cec py/gc: gc_dump_alloc_table(): Dump heap offset instead of actual address.
Address printed was truncated anyway and in general confusing to outsider.
A line which dumps it is still left in the source, commented, for peculiar
cases when it may be needed (e.g. when running under debugger).
2016-05-13 00:16:38 +03:00
Paul Sokolovsky 9a8751b006 gc: gc_dump_alloc_table(): Use '=' char for tail blocks.
'=' is pretty natural character for tail, and gives less dense picture
where it's easier to see what object types are actually there.
2016-05-13 00:16:38 +03:00
Paul Sokolovsky 10503f3534 py/moduerrno: Add EACCES, pretty common error on Unix. 2016-05-13 00:15:38 +03:00
Damien George 9a92499641 py/objexcept: Don't convert errno to str in constructor, do it in print.
OSError's are now printed like:

    OSError: [Errno 1] EPERM

but only if the string corresponding to the errno is found.

Paul Sokolovsky a314b842bb py/emitglue: Fix build on AArch64 (ARMv8, etc.) related to loading .mpy files.
Actual loading of .mpy files isn't tested.

Colin Hogben a896951a9a py/objfloat, py/modmath: Ensure M_PI and M_E defined.
In some compliation enviroments (e.g. mbed online compiler) with
strict standards compliance, <math.h> does not define constants such
as M_PI.  Provide fallback definitions of M_E and M_PI where needed.
