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.

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.

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

Damien George b86c65d31c extmod/modubinascii: Add check for empty buffer passed to hexlify.
Previous to this patch hexlify(b'', b':') would lead to a bad crash due to

Paul Sokolovsky 5da8de2b66 extmod/modlwip: Fix error codes for duplicate calls to connect().
If socket is already connected, POSIX requires returning EISCONN. If

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).

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
to e.g. peek() function returning all of the event fields, not just time.

Damien George b568448306 extmod/modlwip: Use mp_obj_str_get_str instead of mp_obj_str_get_data. 2017-03-26 19:19:35 +11:00
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.
2017-03-22 12:49:21 +11:00
Peter Hinch 231cfc84a7 extmod/modframebuf: Add support for monochrome horizontal format.
MHLSB and MHMSB formats are added to the framebuf module, which have 8
adjacent horizontal pixels represented in a single byte.

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.

Damien George 643876fb77 extmod/vfs_fat: Allow to compile with MICROPY_VFS_FAT disabled.

Paul Sokolovsky 830ce74f32 extmod/modutimeq: Make scheduling fair (round-robin).
By adding back monotonically increasing field in addition to time field.
As heapsort is not stable, without this, among entried added and readded
at the same time instant, some might be always selected, and some might
never be selected, leading to scheduling starvation.

Paul Sokolovsky 0982884655 extmod/modurandom: Use mp_raise_ValueError().
For the standard unix x86_64 build, this saves 11 bytes on object file

- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

Damien George 3625afa173 extmod/vfs: Allow to stat the root directory.

Damien George ec7dc7f8d7 extmod/vfs: Allow to mount a block device, not just a VFS object.
If the mounted object doesn't have a "mount" method then assume it's a
block device and try to detect the filesystem.  Since we currently only
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).
2017-02-08 11:14:23 +03:00
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).
2017-02-06 14:38:33 +11:00
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.

pin = machine.Pin(...)

signal has the same .value() and __call__() methods as a pin.

Damien George f488fa29e4 extmod/modlwip: Add socket.readinto() method. 2017-01-27 21:01:18 +11:00
Damien George 6c23c7587f extmod/vfs: Add ability for VFS sub-system to import using VfsFat. 2017-01-27 17:21:45 +11:00
Damien George fb3ae1784e extmod/vfs_fat: Rework to support new generic VFS sub-system.
The VfsFat object can now be mounted by the generic VFS sub-system.
2017-01-27 17:19:06 +11:00
Damien George dcb9ea7215 extmod: Add generic VFS sub-system.
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
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.
2017-01-27 17:19:06 +11:00
Damien George 32a1138b9f extmod: Rename vfs_fat_file.h to vfs_fat.h.
And move declaration of mp_fat_vfs_type to this file.
2017-01-27 15:04:17 +11:00
Damien George f5f4cdae89 extmod/vfs_fat: Rework so it can optionally use OO version of FatFS.
If MICROPY_VFS_FAT is enabled by a port then the port must switch to using
MICROPY_FATFS_OO.  Otherwise a port can continue to use the FatFs code
without any changes.

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).

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 e5ef15a9d7 py/lexer: Provide generic mp_lexer_new_from_file based on mp_reader.
If a port defines MICROPY_READER_POSIX or MICROPY_READER_FATFS then
lexer.c now provides an implementation of mp_lexer_new_from_file using
the mp_reader_new_file function.
2016-11-16 18:13:51 +11:00
Damien George 6b239c271c py: Factor out persistent-code reader into separate files.
Implementations of persistent-code reader are provided for POSIX systems
and systems using FatFS.  Macros to use these are MICROPY_READER_POSIX and
MICROPY_READER_FATFS respectively.  If an alternative implementation is
needed then a port can define the function mp_reader_new_file.
2016-11-16 18:13:50 +11:00
Paul Sokolovsky 59a1201da9 all: Remove readall() method, which is equivalent to read() w/o args.
Its addition was due to an early exploration on how to add CPython-like
stream interface. It's clear that it's not needed and just takes up
bytes in all ports.
2016-11-14 00:24:22 +03:00
Paul Sokolovsky 0cbc07227c extmod/moduheapq: Adhoc changes to support ordering by utime.ticks_ms().
As required for further elaboration of uasyncio, like supporting baremetal
systems with wraparound timesources. This is not intended to be public
interface, and likely will be further refactored in the future.

Paul Sokolovsky 9b345a9e48 extmod/utime_mphal: ticks_diff/ticks_add: Don't hardcode 32-bit types.
Use normal mp_int_t/mp_uint_t types, algorithms (hm, formulas) can work
with any type width.
2016-11-03 23:54:16 +03:00
Paul Sokolovsky 10bde6933e extmod/utime_mphal: ticks_diff(): Optimize to avoid if conditions. 2016-11-02 02:50:48 +03:00
Paul Sokolovsky e429daa572 extmod/utime_mphal: Fix implementation of new semantics of ticks_diff().
Now the function properly uses ring arithmetic to return signed value
in range (inclusive):
[-MICROPY_PY_UTIME_TICKS_PERIOD/2, MICROPY_PY_UTIME_TICKS_PERIOD/2-1].

That means that function can properly process 2 time values away from
each other within MICROPY_PY_UTIME_TICKS_PERIOD/2 ticks, but away in
both directions. For example, if tick value 'a' predates tick value 'b',
ticks_diff(a, b) will return negative value, and positive value otherwise.
But at positive value of MICROPY_PY_UTIME_TICKS_PERIOD/2-1, the result
of the function will wrap around to negative -MICROPY_PY_UTIME_TICKS_PERIOD/2,
in other words, if a follows b in more than MICROPY_PY_UTIME_TICKS_PERIOD/2 - 1
ticks, the function will "consider" a to actually predate b.

2016-10-29 13:42:36 +03:00
Paul Sokolovsky 6ed5583f8c extmod/utime_mphal: ticks_diff(): switch arg order, return signed value.
Based on the earlier discussed RFC. Practice showed that the most natural
order for arguments corresponds to mathematical subtraction:

ticks_diff(x, y) <=> x - y

Also, practice showed that in real life, it's hard to order events by time
of occurance a priori, events tend to miss deadlines, etc. and the expected
order breaks. And then there's a need to detect such cases. And ticks_diff
can be used exactly for this purpose, if it returns a signed, instead of
unsigned, value. E.g. if x is scheduled time for event, and y is the current
time, then if ticks_diff(x, y) < 0 then event has missed a deadline (and e.g.
needs to executed ASAP or skipped). Returning in this case a large unsigned
number (like ticks_diff behaved previously) doesn't make sense, and such
"large unsigned number" can't be reliably detected per our definition of
ticks_* function (we don't expose to user level maximum value, it can be
anything, relatively small or relatively large).
2016-10-29 05:02:24 +03:00
Paul Sokolovsky f00ecdb54d extmod/moduos_dupterm: Renamed to uos_dupterm.
As part of file naming clean up (moduos_dupterm doesn't implement a
full module, so should skip "mod" prefix, similar to other files in
extmod/).
2016-10-26 02:08:37 +03:00
Damien George 5694201930 extmod/vfs_fat_file: Make file.close() a no-op if file already closed.
As per CPython semantics.  In particular, file.__del__() should not raise
an exception if the file is already closed.
