Damien George f4059dcc0c all: Use NULL instead of "" when calling mp_raise exception helpers.
This is the established way of doing it and reduces code size by a little
bit.

Damien George 9725a654bd extmod/uos_dupterm: Swallow any errors from dupterm closing the stream.
Without this the board will crash when deactivating a stream that doesn't
have a close() method (eg UART) or that raises an exception within the
method (eg user-defined function).
2017-10-19 14:10:17 +11:00
Damien George 37282f8fc1 extmod/uos_dupterm: Update uos.dupterm() and helper funcs to have index.
The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs.  It has minor backwards incompatibility in that
it no longer accepts zero arguments.

The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.

A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.

The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.

Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

Paul Sokolovsky aba1f9167a extmod/modure: Add stack overflow checking when executing a regex. 2017-10-03 00:20:10 +03:00
Paul Sokolovsky c9a0b2a818 extmod/re1.5: Upgrade to v0.8.2, adds hook for stack overflow checking. 2017-10-02 21:20:47 +03:00
Paul Sokolovsky 4a314a6f63 extmod/re1.5: Update to 0.8.1.
Allow literal minus in char classes to be in trailing position, e.g. [a-c-].
(Previously, minus was allowed only at the start.)

This increases ARM Thumb2 code size by 8 bytes.
2017-09-24 10:19:24 +03:00
Damien George b02be234e1 extmod/machine_pinbase: Put PinBase singleton in ROM.
This patch also removes the empty type "pinbase_type" (which crashes if
accessed) and uses "machine_pinbase_type" instead as the type of the
PinBase singleton.
2017-09-12 16:00:21 +10:00
Damien George beeb7483d8 extmod/modussl_mbedtls: Allow to compile with MBEDTLS_DEBUG_C disabled.
With MBEDTLS_DEBUG_C disabled the function mbedtls_debug_set_threshold()
doesn't exist.  There's also no need to call mbedtls_ssl_conf_dbg() so a
few bytes can be saved on disabling that and not needing the mbedtls_debug
callback.
2017-09-06 17:34:45 +10:00
Damien George 4a93801c12 all: Update Makefiles and others to build with new ports/ dir layout.

Damien George 71c9cfb028 all: Convert remaining "mp_uint_t n_args" to "size_t n_args".
This is to have consistency across the whole repository.
2017-08-30 10:59:58 +10:00
Damien George 58321dd985 all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriate
The unary-op/binary-op enums are already defined, and there are no
arithmetic tricks used with these types, so it makes sense to use the
correct enum type for arguments that take these values.  It also reduces
code size quite a bit for nan-boxing builds.

Damien George 4c736ea8fc extmod,unix: For uos.stat interpret st_size member as an unsigned int.
This prevents large files (eg larger than 2gb on a 32-bit arch) from
showing up as having a negative size.  Fixes issue #3227.
2017-08-21 20:47:22 +10:00
Alex Robbins c89254fd0f extmod/modubinascii: Rewrite mod_binascii_a2b_base64.
This implementation ignores invalid characters in the input. This allows
it to decode the output of b2a_base64, and also mimics the behavior of
CPython.
2017-08-17 09:25:51 +03:00
Eric Poulsen d5191edf7f extmod/modussl_mbedtls.c: Add ussl.getpeercert() method.
Behaviour is as per CPython but only the binary form is implemented here.
A test is included.
2017-08-16 15:01:00 +10:00
Javier Candeira 35a1fea90b all: Raise exceptions via mp_raise_XXX
- Changed: ValueError, TypeError, NotImplementedError
  - OSError invocations unchanged, because the corresponding utility
    function takes ints, not strings like the long form invocation.
  - OverflowError, IndexError and RuntimeError etc. not changed for now
    until we decide whether to add new utility functions.
2017-08-13 22:52:33 +10:00
Damien George 0f12082f5b py,extmod,stmhal: Use "static inline" for funcs that should be inline.
"STATIC inline" can expand to "inline" if STATIC is defined to nothing, and
this case can lead to link errors.

Radomir Dopieralski 363087aa11 extmod/modframebuf: Fix invalid stride for odd widths in GS4_HMSB fmt.
Since the stride is specified in pixels, in a 4-bit horizontal format it

Damien George 761e4c7ff6 all: Remove trailing spaces, per coding conventions. 2017-07-19 13:12:10 +10:00
Alexander Steffen 299bc62586 all: Unify header guard usage.
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.

This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.

The rules are as follows.

Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _

In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.

py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h

Paul Sokolovsky 82b9915b34 extmod/modussl_axtls: Implement server_hostname arg to wrap_socket().
As enabled by SNI support in axTLS v2+.
2017-06-14 01:01:12 +03:00
Paul Sokolovsky 75c3f2a7ab extmod/modussl_axtls: Update for axTLS 2.1.3.

Damien George 7ecfbb8267 extmod/vfs: Allow "buffering" and "encoding" args to VFS's open().
These args are currently ignored but are parsed to make it easier to
write portable scripts between CPython and MicroPython.
2017-06-07 15:29:53 +10:00

Paul Sokolovsky 50de6d2fab extmod/modlwip: accept: Fix error code for non-blocking mode.
In non-blocking mode, if no pending connection available, should return
EAGAIN, not ETIMEDOUT.
2017-06-04 13:45:37 +03:00
Paul Sokolovsky 5da8de2b66 extmod/modlwip: Fix error codes for duplicate calls to connect().
If socket is already connected, POSIX requires returning EISCONN. If
connection was requested, but not yet complete (for non-blocking
socket), error code is EALREADY.

2017-06-04 12:30:41 +03:00
Paul Sokolovsky a0dbbbebb8 extmod/modlwip: connect: For non-blocking mode, return EINPROGRESS.

Scott Shawcroft 790c38e18c atmel-samd: Rework boot, main and REPL order.
Boot will only run once now before USB is started. Its output goes to

Damien George d70f688f25 extmod/vfs: Use MP_S_IFDIR, MP_S_IFREG consts instead of magic numbers. 2017-05-10 12:30:34 +10:00
Damien George d4cd4831b0 extmod/vfs_fat: Replace listdir() with implementation of ilistdir().
VfsFat no longer has the listdir() method.  Rather, if listdir()
functionality is needed then one should use uos.listdir() which will call
VfsFat.ilistdir().
2017-05-10 11:39:28 +10:00
Damien George 87283c1974 extmod/vfs: Implement mp_vfs_ilistdir().
uos.ilistdir() is the core function, returning an iterator that yields
3-tuples.  uos.listdir() is implemented in terms of ilistdir().
2017-05-10 11:39:28 +10:00
Damien George c9a3a68a49 extmod/vfs: Allow a VFS to be mounted at the root dir.
This patch allows mounting of VFS objects right at the root directory, eg
os.mount(vfs, '/').  It still allows VFS's to be mounted at a path within
the root, eg os.mount(vfs, '/flash'), and such mount points will override
any paths within a VFS that is mounted at the root.

Paul Sokolovsky 5db55e63f3 extmod/modlwip: ioctl POLL: Fix handling of peer closed socket.
Peer-closed socket is both readable and writable: read will return EOF,
write - error. Without this poll will hang on such socket.

Note that we don't return POLLHUP, based on argumentation in
http://www.greenend.org.uk/rjk/tech/poll.html that it should apply to
deeper disconnects, for example for networking, that would be link layer
disconnect (e.g. WiFi went down).
2017-05-01 18:20:09 +03:00
Paul Sokolovsky 4c2402e41e extmod/modlwip: getaddrinfo: Allow to accept all 6 standard params.

Damien George 61616e84ce extmod/machine_signal: Rename "inverted" arg to "invert", it's shorter.
A shorter name takes less code size, less room in scripts and is faster to
type at the REPL.

Tests and HW-API examples are updated to reflect the change.
2017-04-15 21:01:47 +03:00
Paul Sokolovsky 605ff91efd extmod/machine_signal: Support all Pin's arguments to the constructor.
This implements the orginal idea is that Signal is a subclass of Pin, and
thus can accept all the same argument as Pin, and additionally, "inverted"
param. On the practical side, it allows to avoid many enclosed parenses for
a typical declararion, e.g. for Zephyr:

Signal(Pin(("GPIO_0", 1))).

Of course, passing a Pin to Signal constructor is still supported and is the
most generic form (e.g. Unix port will only support such form, as it doesn't
have "builtin" Pins), what's introduces here is just practical readability
optimization.

"value" kwarg is treated as applying to a Signal (i.e. accounts for possible
inversion).

Peter Hinch 468c6f9da1 extmod/modframebuf: Make monochrome bitmap formats start with MONO_.
MONO_xxx is much easier to read if you're not familiar with the code.
MVLSB is deprecated but kept for backwards compatibility, for the time
being.

This patch also updates the associated docs and tests.
2017-04-04 17:38:33 +10:00
Damien George b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils.
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.
2017-03-31 22:29:39 +11:00
Jan Pochyla e9d7c3ea0e modutimeq: Add peektime() function (provisional).
Allows to get event time for a head item in the queue. The usecase
if waiting for the next event *OR* I/O completion. I/O completion may
happen before event triggers, and then wait should continue for the
remaining event time (or I/O completion may schedule another earlier
event altogether).

The new function has a strongly provisional status - it may be converted

Damien George 2e3fc77809 extmod/utime_mphal: Don't exit/enter the GIL in generic sleep functions.
GIL behaviour should be handled by the port.  And ports probably want to
define sleep_us so that it doesn't release the GIL, to improve timing
accuracy.

Damien George 1831034be1 py: Allow lexer to raise exceptions during construction.
This patch refactors the error handling in the lexer, to simplify it (ie
reduce code size).

A long time ago, when the lexer/parser/compiler were first written, the
lexer and parser were designed so they didn't use exceptions (ie nlr) to
report errors but rather returned an error code.  Over time that has
gradually changed, the parser in particular has more and more ways of
raising exceptions.  Also, the lexer never really handled all errors without
raising, eg there were some memory errors which could raise an exception
(and in these rare cases one would get a fatal nlr-not-handled fault).

This patch accepts the fact that the lexer can raise exceptions in some
cases and allows it to raise exceptions to handle all its errors, which are
for the most part just out-of-memory errors during construction of the
lexer.  This makes the lexer a bit simpler, and also the persistent code
stuff is simplified.

What this means for users of the lexer is that calls to it must be wrapped
in a nlr handler.  But all uses of the lexer already have such an nlr
handler for the parser (and compiler) so that doesn't put any extra burden
on the callers.

Damien George 0a3ac07ec7 extmod/vfs: Rewrite path lookup algo to support relative paths from root.
For example, if the current directory is the root dir then this patch
allows one to do uos.listdir('mnt'), where 'mnt' is a valid mount point.
Previous to this patch such a thing would not work, on needed to do
uos.listdir('/mnt') instead.

If the mounted object doesn't have a "mount" method then assume it's a

support FAT filesystems, the behaviour is to just try and create a VfsFat
object automatically, using the given block device.

Paul Sokolovsky 181f7d1450 extmod/machine_signal: Implement Signal .on() and .off() methods.
Each method asserts and deasserts signal respectively. They are equivalent
to .value(1) and .value(0) but conceptually simpler (and may help to avoid
confusion with inverted signals, where "asserted" state means logical 0
output).

Damien George dee47949cc extmod/machine_spi: Remove EVENT_POLL_HOOK from soft-SPI transfer func.
SPI needs to be fast, and calling the EVENT_POLL_HOOK every byte makes it
unusable for ports that need to do non-trivial work in the EVENT_POLL_HOOK
call.  And individual SPI transfers should be short enough in time that
EVENT_POLL_HOOK doesn't need to be called.

If something like this proves to be needed in practice then we will need
to introduce separate event hook macros, one for "slow" loops (eg
select/poll) and one for "fast" loops (eg software I2C, SPI).

Paul Sokolovsky d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.

Damien George dcb9ea7215 extmod: Add generic VFS sub-system.
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are

then be mounted.

These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.

This feature is controlled by MICROPY_VFS, disabled by default.

Support for Xtensa emitter and assembler, and upgraded F4 and F7 STM HAL

This release adds support for the Xtensa architecture as a target for the
native emitter, as well as Xtensa inline assembler.  The int.from_bytes
and int.to_bytes methods now require a second argument (the byte order)
per CPython (only "little" is supported at this time).  The "readall"
method has been removed from all stream classes that used it; "read" with
no arguments should be used instead.  There is now support for importing
packages from compiled .mpy files.  Test coverage is increased to 96%.

The generic I2C driver has improvements: configurable clock stretching
timeout, "stop" argument added to readfrom/writeto methods, "nack"
argument added to readinto, and write[to] now returns num of ACKs
received.  The framebuf module now handles 16-bit depth (generic colour
format) and has hline, vline, rect, line methods.  A new utimeq module is
added for efficient queue ordering defined by modulo time (to be
compatible with time.ticks_xxx functions).  The pyboard.py script has been
modified so that the target board is not reset between scripts or commands
that are given on a single command line.

For the stmhal port the STM Cube HAL has been upgraded: Cube F4 HAL to
v1.13.1 (CMSIS 2.5.1, HAL v1.5.2) and Cube F7 HAL to v1.1.2.  There is a
more robust pyb.I2C implementation (DMA is now disabled by default, can be
enabled via an option), and there is an implementation of machine.I2C with
robust error handling and hardware acceleration on F4 MCUs.  It is now
recommended to use machine.I2C instead of pyb.I2C.  The UART class is now
more robust with better handling of errors/timeouts.  There is also more
accurate VBAT and VREFINT measurements for the ADC.  New boards that are
supported include: NUCLEO_F767ZI, STM32F769DISC and NUCLEO_L476RG.

For the esp8266 port select/poll is now supported for sockets using the
uselect module.  There is support for native and viper emitters, as well
as an inline assembler (with limited iRAM for storage of native functions,
or the option to store code to flash).  There is improved software I2C
with a slight API change: scl/sda pins can be specified as positional only
when "-1" is passed as the first argument to indicate the use of software
I2C.  It is recommended to use keyword arguments for scl/sda.  There is
very early support for over-the-air (OTA) updates using the yaota8266
project.

Paul Sokolovsky eac22e29a5 all: Consistently update signatures of .make_new and .call methods.
Otherwise, they serve reoccurring source of copy-paste mistakes and
breaking nanbox build.
2017-01-04 16:10:42 +03:00
Paul Sokolovsky 7327966da7 extmod/modutimeq: Make time_less_than be actually "less than", not less/eq.
This fixes an obvious case of non-fair scheduling of 2 tasks with the same
deadline.
2016-12-24 00:06:29 +03:00

Paul Sokolovsky ffe807f349 extmod/moduheapq: Revert change for adhoc relative-time queue support.
Now that specialized utimeq module has been implenented, revert previous
adhoc changes to uheapq.

This reverts commit 0cbc07227c.

    q = utimeq.utimeq(10)
    q.push(utime.ticks_ms(), data1, data2)

Damien George 898d4c1217 extmod/modframebuf: Make framebuf implement the buffer protocol.
So that one can easily access the underlying data of the frame buffer, eg
to write the data out to a display.
2016-12-08 15:17:47 +11:00
Damien George 1eb3c66e91 extmod/machine_spi: Provide reusable software SPI class.
So long as a port defines relevant mp_hal_pin_xxx functions (and delay) it
can make use of this software SPI class without the need for additional
code.
2016-12-08 13:47:01 +11:00
Damien George 374ed317c5 extmod/modframebuf: Add hline, vline, rect and line methods.
These are basic drawing primitives.  They work in a generic way on all
framebuf formats by calling the underlying setpixel or fill_rect C-level
primitives.
2016-12-05 11:52:51 +11:00
Paul Sokolovsky 4463d8a910 extmod/modbtree: Rename "sync" method to "flush" for consistency.
Rename recently introduced "sync" method to "flush" for consistency with
usual files.
2016-12-05 01:50:55 +03:00
w4kpm ec22d1739d extmod/modbtree: Add method to sync the database.
If you have longish operations on the db (such as logging data) it may
be desirable to periodically sync the database to the disk.  The added
btree.sync() method merely exposes the berkley __bt_sync function to the
user.
2016-12-02 17:30:53 +11:00
w4kpm bd476acd41 extmod/vfs_fat_file: Allow file obj to respond to ioctl flush request. 2016-12-02 17:26:37 +11:00
Damien George cb53226b0c extmod/modlwip: Add ioctl method to socket, with poll implementation.
Implementation of polling may need further fine tuning, but basic
functionality works (tested on esp8266).
2016-12-02 16:41:51 +11:00
Damien George 2d329c4a56 extmod/moduselect: Use configurable EVENT_POLL_HOOK instead of WFI.
To make moduselect be usable by any port.
2016-12-02 16:40:39 +11:00
Damien George ebc8d730f1 extmod/moduselect: Use stream helper function instead of ad-hoc code. 2016-12-02 16:39:50 +11:00
Damien George 304cfda8c4 py/stream: Move ad-hoc ioctl constants to stream.h and rename them.
The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.
2016-12-02 16:37:29 +11:00
Damien George b7df3e541a extmod/vfs_fat: Implement POSIX behaviour of rename, allow to overwrite.
If the destination of os.rename() exists then it will be overwritten if it
is a file.  This is the POSIX behaviour, which is also the CPython
behaviour, and so we follow suit.

See issue #2598 for discussion.
2016-12-02 15:06:09 +11:00
Damien George a081b49d55 extmod/modframebuf: Optimise fill and fill_rect methods.
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.

This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.
2016-12-01 16:51:31 +11:00
Damien George 81e171b7bb extmod/modframebuf: Add back legacy FrameBuffer1 "class".
For backwards compatibility.  It simple creates a frame buffer with the
MVLSB format.
2016-12-01 16:43:25 +11:00
Radomir Dopieralski 225e22b287 extmod/modframebuf: Make FrameBuffer handle 16bit depth.
Rename FrameBuffer1 into FrameBuffer and make it handle different bit
depths via a method table that has getpixel and setpixel.  Currently
supported formats are MVLSB (monochrome, vertical, LSB) and RGB565.

Also add blit() and fill_rect() methods.

Damien George 5d2279bec1 extmod/machine_i2c: Add hook to constructor to call port-specific code.
If MICROPY_PY_MACHINE_I2C_MAKE_NEW is defined then it is called when an
I2C object is constructed with an id which is not -1.
2016-11-24 00:12:51 +11:00
Damien George 8b74048d2a extmod/machine_i2c: Expose soft I2C obj and readfrom/writeto funcs.
