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.

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.

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.

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.

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.

Paul Sokolovsky 76146b3d9a extmod/utime_mphal: Allow ticks functions period be configurable by a port.

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).

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/).

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.

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 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.

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.

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.

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.

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.

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.

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).

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.

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.)

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
function.  The coding pattern follows the stream protocol and helper
methods.
2016-09-01 15:07:20 +10:00
Damien George 531217a06b extmod/modframebuf: Fix pixel accessor to return a 1-bit result. 2016-08-27 18:31:58 +10:00
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
methods on the vfs object.  Some internals had to be exposed (the STATIC
keyword removed) for this to work.

Fixes #2338.

Krzysztof Blazewicz 5a5449d4eb extmod/modbtree: do CHECK_ERROR after __bt_seq()
In `btree_seq()`, when `__bt_seq()` gets called with invalid

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 efee577318 extmod/machine_pinbase: Fix nanbox build.
MP_ROM_PTR() is only for data structures initialization, code should use
MP_OBJ_FROM_PTR().
2016-06-19 00:26:57 +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.
2016-06-18 23:40:28 +03:00
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 080137961d extmod/modbtree: open(): Support "in-memory" database with filename=None.
It's not really in-memory though, just uses anonymous temporary file on
disk.

Robert HH 23067a1422 esp8266: Use RTC to set date & time stamps for files.
The time stamp is taken from the RTC for all newly generated
or changed files. RTC must be maintained separately.
The dummy time stamp of Jan 1, 2000 is set in vfs.stat() for the
root directory, avoiding invalid time values.
2016-06-16 19:31:58 +03:00
Paul Sokolovsky d0416ff915 extmod/modbtree: Actually implement end key support for .items(). 2016-06-16 18:16:33 +03:00

Paul Sokolovsky 8072162170 extmod/modbtree: Initial implementation of "btree" module based on BerkeleyDB.
This implements basic wrapping of native get/put/seq API, and then dictionary
access protocol. Native API is intended to be superceded going forward.
2016-06-14 21:51:59 +03:00
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
Paul Sokolovsky 298c2ae2c7 extmod/vfs_fat: Mark anused "self" arg for fat_vfs_stat(). 2016-05-31 15:42:08 +03:00
Robert HH ee009d713a extmod/vfs_fat.c: Add vfs.stat().
The call to stat() returns a 10 element tuple consistent to the os.stat()
call. At the moment, the only relevant information returned are file
type and file size.
2016-05-31 13:03:12 +03:00
Paul Sokolovsky 480159ca8b extmod/vfs_fat: getcwd(): Use mp_obj_new_exception_arg1().
Copy-paste issue, with the original mistake in stmhal.
2016-05-29 20:04:53 +03:00
Paul Sokolovsky ee5e3f6527 extmod/vfs_fat: chdir(), getcwd() methods should accept VFS object (self). 2016-05-29 18:52:41 +03:00
Paul Sokolovsky cac6c9704e extmod/vfs_fat: Add getcwd() method.
Ported from stmhal.
2016-05-29 18:23:59 +03:00
Paul Sokolovsky f12146cbf6 extmod/vfs_fat: Add chdir() method.
Ported from stmhal.
2016-05-29 18:17:00 +03:00
Robert HH 7c004e794c extmod/vfs_fat*: Replace text error messages by POSIX error numbers.
These changes are in line with similar changes in other modules, and
with standard Python interface.
2016-05-27 23:57:01 +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
Damien George 4b37e775ea extmod/machine_i2c: Redo mp_hal_pin macros to use open_drain and od_low.
mp_hal_pin_config_od is renamed mp_hal_pin_open_drain, and mp_hal_pin_low
is mp_hal_pin_od_low.
2016-05-26 17:06:40 +01:00
Paul Sokolovsky 2ea019f3d3 extmod/modussl: Coverage build fixes. 2016-05-26 02:11:24 +03:00
Paul Sokolovsky 9d04fec5d9 extmod/modussl: Make more compatible with non-default obj representations.
Still not compatible with nanboxing.
2016-05-26 02:10:35 +03:00
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).
2016-05-20 22:20:37 +03:00
Paul Sokolovsky 3a29db8e58 extmod/modwebrepl: Add close() method. 2016-05-20 21:32:41 +03:00
Paul Sokolovsky ccf4e5ab7b extmod/modwebsocket: Add close() method. 2016-05-20 21:18:49 +03:00
Damien George f9dc644017 extmod: When including extmod headers, prefix path with extmod/. 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.
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.
2016-05-15 22:42:12 +03:00
Damien George 0055457b5f extmod/modlwip: Convert errno's to use MP_Exxx symbols. 2016-05-12 12:49:14 +01:00
Paul Sokolovsky cfc94bec9f extmod/modlwip: Implement sendall() method for TCP sockets. 2016-05-03 10:43:11 +03:00
Paul Sokolovsky b8468d12a1 extmod/modwebrepl: Get rid of using strncpy(). 2016-05-02 20:52:34 +03:00
Paul Sokolovsky 859e4e94f3 extmod/modwebrepl: Add support for password.
Request for password then becomes mandatory part of the protocol.
2016-04-30 20:36:32 +03:00
Paul Sokolovsky 18775d3807 extmod/modwebrepl: Set debugging by default to off.
That's production setting. Also, extra UART output may affect behavior of
(subpar) network drivers.
2016-04-29 19:17:37 +03:00
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.
2016-04-29 18:43:19 +03:00
Paul Sokolovsky b3bc2ee1b9 extmod/modwebrepl: More detailed debug output.
So detailed that even commented by default.
2016-04-29 17:37:40 +03:00
Paul Sokolovsky 473b639845 extmod/modwebrepl: GET_FILE: Send length-prefix chunk with one write().
A bit of optimization.
2016-04-29 17:35:21 +03:00
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.
2016-04-29 01:05:02 +03:00
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.
2016-04-28 17:29:11 +03:00
Paul Sokolovsky 2534bfdb92 extmod/modussl: Support server-side SSL sockets.
wrap_socket(sock, server_side=True)
2016-04-28 17:27:20 +03:00

Paul Sokolovsky 480c212009 extmod/modwebsocket: Handle CLOSE control frame.
This fixes situation when clients hangs waiting for disconnect and does
so only on timeout.
2016-04-27 12:49:30 +03:00
Paul Sokolovsky 1c6d91d968 extmod/modlwip: Add print_pcbs() debug function.
This requires lwIP built with LWIP_DEBUG (or it will be no-op).
2016-04-26 16:30:13 +03:00
Damien George 45ac5a85d5 extmod/modlwip: Workaround esp8266 sendto issue where 1 is returned. 2016-04-26 13:19:08 +01:00

Paul Sokolovsky 7a012f4793 extmod/modlwip: Protect recv/accept Python callback against exceptions.
Using usual call_function_*_protected() helper, to avoid NLR jump crashes.
2016-04-25 21:27:55 +03:00
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.
2016-04-17 18:06:45 +03:00
Paul Sokolovsky 8007f84cca extmod/modlwip: lwip_tcp_receive(): Full error handling. 2016-04-17 02:22:26 +03:00

Paul Sokolovsky fef0d9818a extmod/modlwip: lwip_tcp_receive(): Properly handle EOF for non-blocking sock. 2016-04-14 00:59:09 +03:00
Paul Sokolovsky 59a4fee516 extmod/modwebsocket: Another case to propagate EOF. 2016-04-13 22:17:09 +03:00
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.
2016-04-13 16:34:11 +03:00
