Paul Sokolovsky 1b44987d0c extmod/modutimeq: Fix warning about unused param. 2016-12-22 00:48:19 +03:00
Paul Sokolovsky d02f6a9956 extmod/modutimeq: Refactor into optimized class.
import utimeq, utime
    # Max queue size, the queue allocated statically on creation
    q = utimeq.utimeq(10)
    q.push(utime.ticks_ms(), data1, data2)
    res = [0, 0, 0]
    # Items in res are filled up with results
    q.pop(res)

Paul Sokolovsky ef23399e32 extmod/modutimeq: Copy of current moduheapq with timeq support for refactoring. 2016-12-22 00:23:11 +03:00
Damien George adf3cb5081 extmod/modframebuf: Store underlying buffer object to prevent GC free. 2016-12-09 12:58:45 +11:00
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.
2016-12-01 16:43:25 +11:00
Damien George 8b8242954e extmod/modurandom: Allow to build with float disabled. 2016-11-30 12:58:54 +11:00
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.
For external use by ports if needed.
2016-11-24 00:11:45 +11:00
Damien George 4c905616f0 extmod/machine_i2c: Remove trivial function wrappers. 2016-11-23 17:05:38 +11:00
Damien George 37333cb00a extmod/machine_i2c: Add 'stop' argument to i2c readfrom/writeto meths. 2016-11-23 17:05:38 +11:00
Damien George 0bc99b4836 extmod/machine_i2c: Make i2c.write[to] methods return num of ACKs recvd. 2016-11-23 17:05:38 +11:00
Damien George 07e83573c8 extmod/machine_i2c: Add 'nack' argument to i2c.readinto. 2016-11-23 17:05:38 +11:00
Damien George ced240e72a extmod/machine_i2c: Make C-level functions return -errno on I2C error. 2016-11-23 17:05:38 +11:00
Damien George 946f8dd46f extmod/machine_i2c: Remove unneeded i2c_write_mem/i2c_read_mem funcs. 2016-11-23 17:05:38 +11:00

Paul Sokolovsky 8f5bc3ffc0 stmhal/moduselect: Move to extmod/ for reuse by other ports. 2016-11-21 00:05:56 +03:00
Radomir Dopieralski e81a5353cb extmod/machine_i2c: Release SDA on bus error 2016-11-17 12:43:13 +11:00
Radomir Dopieralski 9a82b67f39 extmod/machine_i2c: Raise an error when clock stretching times out 2016-11-17 12:43:13 +11:00
Radomir Dopieralski 702928915c extmod/machine_i2c: Make the clock stretching timeout configurable 2016-11-17 12:43:12 +11:00
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.
2016-11-12 02:33:17 +03:00
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.
2016-10-30 03:07:22 +03:00
Paul Sokolovsky 76146b3d9a extmod/utime_mphal: Allow ticks functions period be configurable by a port.
Using MICROPY_PY_UTIME_TICKS_PERIOD config var.
2016-10-30 03:02:07 +03:00
Paul Sokolovsky d86cac4b82 extmod/utime_mphal: Implement ticks_add(), add to all maintained ports. 2016-10-29 17:30:05 +03:00
Paul Sokolovsky 6a87084019 extmod/utime_mphal: Add MP_THREAD_GIL_EXIT/ENTER warppers for sleep functions.
Ported from unix port.
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.
2016-10-24 12:59:20 +11:00
Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.
2016-10-21 16:26:01 +11:00
Alex March 84679e0c06 extmod/vfs_fat_file: Check fatfs f_sync() and f_close() returns for errors. 2016-10-19 15:57:07 +11:00
Paul Sokolovsky 06234a6115 extmod/modussl_mbedtls: Add dummy setblocking() method.
Accepts only value of True.
2016-10-15 23:46:13 +03:00
Paul Sokolovsky 36f97f19b4 extmod/utime_mphal: sleep_us/ms(): Don't wait on negative argument. 2016-10-14 22:19:45 +03:00
Paul Sokolovsky a97284423e extmod/utime_mphal: Factor out implementations in terms of mp_hal_* for reuse.
As long as a port implement mp_hal_sleep_ms(), mp_hal_ticks_ms(), etc.
functions, it can just use standard implementations of utime.sleel_ms(),
utime.ticks_ms(), etc. Python-level functions.
2016-10-14 20:14:01 +03:00
Damien George f2f8ae110b extmod/modujson: Fix nanbox build. 2016-10-13 12:09:18 +11:00
Damien George e93c1ca5da extmod/modujson: Implement ujson.load() to load JSON from a stream.
This refactors ujson.loads(s) to behave as ujson.load(StringIO(s)).

Increase in code size is: 366 bytes for unix x86-64, 180 bytes for
stmhal, 84 bytes for esp8266.
2016-10-13 11:46:14 +11:00
Alex March d02f3a57f4 extmod/vfs_fat: Add file and directory checks for remove and rmdir. 2016-10-11 16:03:52 +11:00
Radomir Dopieralski eaef6b5324 extmod/machine_i2c: Use writes not reads in i2c.scan().
As per discussion in #2449, using write requests instead of read requests
for I2C.scan() seems to support a larger number of devices, especially
ones that are write-only.  Even a read-only I2C device has to implement
writes in order to be able to receive the address of the register to read.
2016-10-11 15:30:46 +11:00
Paul Sokolovsky 39968aaaff extmod/uzlib: Update to upstream v2.1.
Adds check that LZ offsets fall into the sliding dictionary used. This
catches a case when uzlib.DecompIO with a smaller dictionary is used
to decompress data which was compressed with a larger dictionary.
Previously, this would lead to producing invalid data or crash, now
an exception will be thrown.
2016-10-11 07:13:23 +03:00
Damien George dc43508cc2 extmod/vfs_fat_file: Use MP_Exxx errno constants. 2016-10-07 14:14:41 +11:00
Damien George 75af908c0e extmod: Use mp_raise_OSError helper function. 2016-10-07 13:52:14 +11:00
Damien George 06d0083468 extmod/modlwip: Use mp_raise_OSError helper function.
Reduces esp8266 code size by about 230 bytes.
2016-10-07 13:47:57 +11:00
Damien George 620c4c32bf extmod/vfs_fat: Use mp_raise_OSError helper function. 2016-10-07 13:44:55 +11:00
Damien George b0eb0d6153 extmod/machine_spi: Add optional support for fast software SPI.
If a port defines MICROPY_PY_MACHINE_SPI_MIN_DELAY then it can use a
faster software SPI loop that does not make calls to the delay_us
function.
2016-10-04 13:46:40 +11:00
Damien George b932b2dd1f extmod/machine_spi: Use delay_half, not baudrate, for internal timing.
The delay_half parameter must be specified by the port to set up the
timing of the software SPI.  This allows the port to adjust the timing
value to better suit its timing characteristics, as well as provide a
more accurate printing of the baudrate.
2016-10-04 13:43:02 +11:00
Damien George d434ce3fca extmod/machine_spi: Factor out software SPI code from esp8266 to extmod. 2016-10-03 16:43:44 +11:00
Damien George 5bb28c7f10 extmod/machine_spi: Simplify SPI xfer function to only take one buf len.
There is no need to take src_len and dest_len arguments.  The case of
reading-only with a single output byte (originally src_len=1, dest_len>1)
is now handled by using the output buffer as the input buffer, and using
memset to fill the output byte into this buffer.  This simplifies the
implementations of the spi_transfer protocol function.
2016-10-03 12:39:31 +11:00
Radomir Dopieralski 219245e10f extmod/machine_i2c: Add support for the addrsize parameter in mem xfers.
The memory read/write I2C functions now take an optional keyword-only
parameter that specifies the number of bits in the memory address.
Only mem-addrs that are a multiple of 8-bits are supported (otherwise
the behaviour is undefined).

Due to the integer type used for the address, for values larger than 32
bits, only 32 bits of address will be sent, and the rest will be padded
with 0s. Right now no exception is raised when that happens. For values
smaller than 8, no address is sent. Also no exception then.

Tested with a VL6180 sensor, which has 16-bit register addresses.

Due to code refactoring, this patch reduces stmhal and esp8266 builds
by about 50 bytes.
2016-09-28 14:45:29 +10:00
Alex March dcf14c1b18 extmod/vfs_fat: Add fat_vfs_statvfs(), reused from stmhal. 2016-09-27 13:48:45 +10:00
Paul Sokolovsky 67d52d8cb9 extmod/uzlib/: Update uzlib to v2.0.3.
Fixes for more pedantic warnings.
2016-09-24 16:07:18 +03:00
Paul Sokolovsky 7b901d6fb7 extmod/moduzlib: DecompIO: Add support for gzip-formatted streams.
This uses extension introduced in CPython 3.5: if wbits (dictionary size
code) has value 16 + 8..15, it means that gzip-formatted stream expected.
2016-09-24 15:30:11 +03:00
Paul Sokolovsky d8a4d9d67c extmod/uzlib: Add tinfgzip.c (gzip header parsing) from upstream. 2016-09-24 15:28:51 +03:00
Paul Sokolovsky 46ab042230 extmod/modussl_mbedtls: Add server_hostname param for wrap_socket().
In CPython, module-level .wrap_socket() function actually doesn't accept
(or document) this param, only SSLContext.wrap_socket() has.
2016-09-23 01:44:23 +03:00
Radomir Dopieralski ec078af985 extmod/machine_i2c: Add clock stretching support.
When the clock is too fast for the i2c slave, it can temporarily hold
down the scl line to signal to the master that it needs to wait. The
master should check the scl line when it is releasing it after
transmitting data, and wait for it to be released.

This change has been tested with a logic analyzer and an i2c slace
implemented on an atmega328p using its twi peripheral, clocked at 8Mhz.
Without the change, the i2c communication works up to aboy 150kHz
frequency, and above that results in the slave stuck in an unresponsive
state. With this change, communication has been tested to work up to
400kHz.
2016-09-22 14:10:02 +10:00
Paul Sokolovsky 080e4d44f3 extmod/modussl_mbedtls: Use 2-component include paths.
This is required to use mbedTLS versions from various sources, e.g.
mainline vs embedded into Zephyr RTOS.
2016-09-22 01:30:48 +03:00
Paul Sokolovsky 5f0ecb72c2 extmod/modussl_mbedtls: Implement key= and cert= args to wrap_socket().
Unlike standard keyfile= and certfile=, these accept byte buffer objects
(to not depend on FS implementation).
2016-09-22 00:17:44 +03:00
Pavol Rusnak 7f5a541b84 extmod/modubinascii: Fix crc32() function on 32-bit platforms. 2016-09-21 21:40:18 +03:00
Stefan Agner b84e1231c9 extmod/uctypes: Allow full 32-bit address range.
Use mp_obj_int_get_truncated to allow the full 32-bit address range
as first parameter.
2016-09-21 21:37:08 +03:00
Paul Sokolovsky 9ea2882317 extmod/modussl_mbedtls: Initial implementation of mbedTLS ussl module. 2016-09-21 21:25:33 +03:00
Damien George 93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.
2016-09-22 00:23:16 +10:00
Radomir Dopieralski 778729c597 extmod/framebuf: Add the xstep!=0 case to scroll() method.
Adds horizontal scrolling. Right now, I'm just leaving the margins
created by the scrolling as they were -- so they will repeat the
edge of the framebuf. This is fast, and the user can always fill
the margins themselves.
2016-09-05 12:06:56 +10:00
Paul Sokolovsky 1bc5cb4312 extmod/moduzlib: Support wbits arg to DecompIO. 2016-09-04 14:44:12 +03:00
Damien George 47899a1ab8 extmod/modframebuf: Include font from stmhal directory explicitly.
So that users of framebuf don't need to have stmhal directory in their
path.  (Eventually the font can be moved elsewhere.)
2016-09-04 16:39:28 +10:00
Paul Sokolovsky f7c4611523 extmod/moduzlib: Use mperrno.h for error constants. 2016-09-03 00:34:57 +03:00
Paul Sokolovsky a6864a13c7 extmod/moduzlib: Implement zlib stream decompressor class, DecompIO. 2016-09-03 00:19:35 +03:00
Radomir Dopieralski 41ec22632d extmod/modframebuf: Fix fill and scroll when height not divisible by 8.
There was a bug in `framebuf1_fill` function, that makes it leave a few
lines unfilled at the bottom if the height is not divisible by 8.

A similar bug is fixed in the scroll method.
2016-09-02 23:58:34 +10:00
Damien George 0823c1baf8 extmod: Add machine_spi with generic SPI C-protocol and helper methods.
The idea is that all ports can use these helper methods and only need to
provide initialisation of the SPI bus, as well as a single transfer

Radomir Dopieralski d29ca28288 esp8266/modous: Add os.umount method to unmount a filesystem.
This is an object-oriented approach, where uos is only a proxy for the

In `btree_seq()`, when `__bt_seq()` gets called with invalid
`flags` argument it will return `RET_ERROR` and it won't
initialize `val`. If field `data` of uninitialized `val`
is passed to `mp_obj_new_bytes()` it causes a segfault.

Paul Sokolovsky 5071ceea07 extmod/modlwip: Store a chain of incoming pbufs, instead of only one.
Storing a chain of pbuf was an original design of @pfalcon's lwIP socket
module. The problem with storing just one, like modlwip does is that
"peer closed connection" notification is completely asynchronous and out of
band. So, there may be following sequence of actions:

1. pbuf #1 arrives, and stored in a socket.
2. pbuf #2 arrives, and rejected, which causes lwIP to put it into a
queue to re-deliver later.
3. "Peer closed connection" is signaled, and socket is set at such status.
4. pbuf #1 is processed.
5. There's no stored pbufs in teh socket, and socket status is "peer closed
connection", so EOF is returned to a client.
6. pbuf #2 gets redelivered.

Apparently, there's no easy workaround for this, except to queue all
incoming pbufs in a socket. This may lead to increased memory pressure,
as number of pending packets would be regulated only by TCP/IP flow
control, whereas with previous setup lwIP had a global overlook of number
packets waiting for redelivery and could regulate them centrally.

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).

Paul Sokolovsky 0ab372585f extmod/moduos_dupterm: Dumpterm subsystem is responsible for closing stream.
Make dupterm subsystem close a term stream object when EOF or error occurs.
There's no other party than dupterm itself in a better position to do this,
and this is required to properly reclaim stream resources, especially if
multiple dupterm sessions may be established (e.g. as networking
connections).

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.
2016-05-18 02:41:45 +03:00
Paul Sokolovsky afce978aca extmod/modlwip: Rework how Python accept callback is called.
Calling it from lwIP accept callback will lead incorrect functioning
and/or packet leaks if Python callback has any networking calls, due
to lwIP non-reentrancy. So, instead schedule "poll" callback to do
that, which will be called by lwIP when it does not perform networking
activities. "Poll" callback is called infrequently though (docs say
every 0.5s by default), so for better performance, lwIP needs to be
patched to call poll callback soon after accept callback, but when
current packet is already processed.

Paul Sokolovsky b0f3ae58e7 extmod/modwebrepl: Add rate-limiting workaround for broken network drivers.
Like ESP8266 has.
2016-04-29 19:14:03 +03:00
Paul Sokolovsky 8811b0af9c extmod/modwebrepl: Use bigger socket receive buffer.
The smaller chunks we send (and receive), the more packets there to
receive, and higher chance to git internal packet buffer overflow in
WiFi driver.

Paul Sokolovsky f41e1f1bb7 extmod/modwebrepl: Keep reading data when there's something to read.
EAGAIN should be returned only if underlying socket returned it. Wrap
existing read function into external loop to process all data available.

Paul Sokolovsky 6514ff6160 extmod/modwebrepl: Initial implementation of "get file" operation. 2016-04-29 01:02:39 +03:00
Paul Sokolovsky 25d0f7d59d extmod/modwebrepl: Module to handle WebREPL protocol.
While just a websocket is enough for handling terminal part of WebREPL,
handling file transfer operations requires demultiplexing and acting
upon, which is encapsulated in _webrepl class provided by this module,
which wraps a websocket object.
2016-04-29 00:52:52 +03:00
Paul Sokolovsky ba61480df5 extmod/modussl: SSL_OK from ssl_read() means "no user data so far".
SSL_OK is numeric 0, and it's *not* an EOF. So, should keep reading.

so only on timeout.
2016-04-27 12:49:30 +03:00
Paul Sokolovsky 1c6d91d968 extmod/modlwip: Add print_pcbs() debug function.

Damien George 624738ca64 extmod/machine_i2c: Allow mp_hal_pin_obj_t to be any type, not a ptr. 2016-04-22 09:56:02 +01:00
Paul Sokolovsky 7d57037906 extmod/modlwip: Add ability to run callback on "recv" and "accept" events.
To use: .setsockopt(SOL_SOCKET, 20, lambda sock: print(sock)). There's a
single underlying callback slot. For normal sockets, it serves as data
received callback, for listening sockets - connection arrived callback.

Paul Sokolovsky 54ea253f56 extmod/moduos_dupterm: Don't swallow exceptions in dupterm's read()/write().
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.

Paul Sokolovsky 7063210014 extmod/modlwip: Fix for loss of data in unaccepted incoming sockets.
When lwIP creates a incoming connection socket of a listen socket, it
sets its recv callback to one which discards incoming data. We set
proper callback only in accept() call, when we allocate Python-level
socket where we can queue incoming data. So, in lwIP accept callback
be sure to set recv callback to one which tells lwIP to not discard
incoming data.

Paul Sokolovsky 5b1c221785 extmod/modwebsocket: Add option for blocking writes to non-blk sockets.
This is strange asymmetry which is sometimes needed, e.g. for WebREPL: we
want to process only available input and no more; but for output, we want
to get rid of all of it, because there's no other place to buffer/store
it. This asymmetry is akin to CPython's asyncio asymmetry, where reads are
asynchronous, but writes are synchronous (asyncio doesn't expect them to
block, instead expects there to be (unlimited) buffering for any sync write
to completely immediately).

Damien George 4f64f6bfd3 extmod/modlwip: Still process remaining incoming data of a closed socket.
It can happen that a socket gets closed while the pbuf is not completely
drained by the application.  It can also happen that a new pbuf comes in
via the recv callback, and then a "peer closed" event comes via the same
callback (pbuf=NULL) before the previous event has been handled.  In both
cases the socket is closed but there is remaining data.  This patch makes
sure such data is passed to the application.

Damien George b33a770596 extmod/fsusermount: Support mounting of multiple block devices.
This patch adds support to fsusermount for multiple block devices
(instead of just one).  The maximum allowed is fixed at compile time by
the size of the fs_user_mount array accessed via MP_STATE_PORT, which
in turn is set by MICROPY_FATFS_VOLUMES.

With this patch, stmhal (which is still tightly coupled to fsusermount)
is also modified to support mounting multiple devices   And the flash and
SD card are now just two block devices that are mounted at start up if
they exist (and they have special native code to make them more
efficient).

Damien George c33ad60a67 extmod/fsusermount: Change block protocol to support ioctl method.
The new block protocol is:
- readblocks(self, n, buf)
- writeblocks(self, n, buf)
- ioctl(self, cmd, arg)

The new ioctl method handles the old sync and count methods, as well as
a new "get sector size" method.

The old protocol is still supported, and used if the device doesn't have
the ioctl method.
