Thorsten von Eicken e880c8dfaa travis: Split esp32 ESP-IDF v3 and v4 builds to separate jobs.
To make it easier to see what is happening when there is a failure.  This
commit also fixes the ESP-IDF v4 build to use the correct GCC 8.2.0.

Damien George e292296d52 py/objexcept: Remove optional TimeoutError exception.
TimeoutError was added back in 077812b2ab for
the cc3200 port. In f522849a4d the cc3200
port enabled use of it in the socket module aliased to socket.timeout.  So
it was never added to the builtins.  Then it was replaced by
OSError(ETIMEDOUT) in 047af9b10b.

The esp32 port enables this exception, since the very beginning of that
port, but it could never be accessed because it's not in builtins.

It's being removed: 1) to not encourage its use; 2) because there are a lot
of other OSError subclasses which are not defined at all, and having
TimeoutError is a bit inconsistent.

Note that ports can add anything to the builtins via MICROPY_PORT_BUILTINS.
And they can also define their own exceptions using the
MP_DEFINE_EXCEPTION() macro.

Damien George 4914731e58 py/parse: Remove unnecessary check in const folding for ** operator.
In this part of the code there is no way to get the ** operator, so no need
to check for it.

This commit also adds tests for this, and other related, invalid const
operations.

stijn bd5633778f travis: Make OSX build work again by not installing pkgconfig.
Recent builds are failing with the following error:

    Error: pkg-config 0.29.2 is already installed

Assuming this will be the case form now on, we don't have to install
pkgconfig anymore.

Damien George 899e89d4c6 extmod/btstack: Pass through SCAN_RSP events.
The latest version of BTstack has a bug fixed so that it correctly
configures scan parameters if they are set right after activating the
stack.  This means that BLE.gap_scan() will correctly set the scanning to
passive and so SCAN_RSP events are not passed through, so we don't need to
explicitly filter them in our bindings.

Making it more specific to use 0x02 for display with an aspect ratio > 2
(resolutions 96x16 and 128x32) and 0x12 for all other sizes as recommended
by @mcauser.  Tested with a 64x32 display which did not work before.

Jim Mussared def76fe4d9 all: Use MP_ERROR_TEXT for all error messages. 2020-04-05 15:02:06 +10:00
Jim Mussared 85858e72df py/objexcept: Allow compression of exception message text.
The decompression of error-strings is only done if the string is accessed
via printing or via er.args.  Tests are added for this feature to ensure
the decompression works.

Jim Mussared 154b4eb354 py: Implement "common word" compression scheme for error messages.
The idea here is that there's a moderate amount of ROM used up by exception
text.  Obviously we try to keep the messages short, and the code can enable
terse errors, but it still adds up.  Listed below is the total string data
size for various ports:

    bare-arm 2860
    minimal 2876
    stm32 8926  (PYBV11)
    cc3200 3751
    esp32 5721

This commit implements compression of these strings.  It takes advantage of
the fact that these strings are all 7-bit ascii and extracts the top 128
frequently used words from the messages and stores them packed (dropping
their null-terminator), then uses (0x80 | index) inside strings to refer to
these common words.  Spaces are automatically added around words, saving
more bytes.  This happens transparently in the build process, mirroring the
steps that are used to generate the QSTR data.  The MP_COMPRESSED_ROM_TEXT
macro wraps any literal string that should compressed, and it's
automatically decompressed in mp_decompress_rom_string.

There are many schemes that could be used for the compression, and some are
included in py/makecompresseddata.py for reference (space, Huffman, ngram,
common word).  Results showed that the common-word compression gets better
results.  This is before counting the increased cost of the Huffman
decoder.  This might be slightly counter-intuitive, but this data is
extremely repetitive at a word-level, and the byte-level entropy coder
can't quite exploit that as efficiently.  Ideally one would combine both
approaches, but for now the common-word approach is the one that is used.

For additional comparison, the size of the raw data compressed with gzip
and zlib is calculated, as a sort of proxy for a lower entropy bound.  With
this scheme we come within 15% on stm32, and 30% on bare-arm (i.e. we use
x% more bytes than the data compressed with gzip -- not counting the code
overhead of a decoder, and how this would be hypothetically implemented).

The feature is disabled by default and can be enabled by setting
MICROPY_ROM_TEXT_COMPRESSION at the Makefile-level.

Jim Mussared 1921224272 extmod/modubinascii: Make code private and module self-contained.
This commit makes all functions and function wrappers in modubinascii.c
STATIC and conditional on the MICROPY_PY_UBINASCII setting, which will
exclude the file from qstr/ compressed-string searching when ubinascii is
not enabled.  The now-unused modubinascii.h header file is also removed.

The cc3200 port is updated accordingly to use this module in its entirety
instead of providing its own top-level definition of ubinascii.

This was originally like this because the cc3200 port has its own ubinascii
module which referenced these methods.  The plan appeared to be that the
API might diverge (e.g. hardware crc), but this should be done similar to
I2C/SPI via a port-specific handler, rather than the port having its own
definition of the module.  Having a centralised module definition also
enforces consistency of the API among ports.

Jim Mussared c34e7b9d4c py/dynruntime.mk: Set MICROPY_ENABLE_DYNRUNTIME instead of per module.
So this setting could be used by other source files if needed.

Jim Mussared a9a745e4b4 py: Use preprocessor to detect error reporting level (terse/detailed).
Instead of compiler-level if-logic.  This is necessary to know what error
strings are included in the build at the preprocessor stage, so that string
compression can be implemented.

Damien George 312c699491 esp32: Change from FAT to littlefs v2 as default filesystem.
This commit changes the default filesystem type for esp32 to littlefs v2.
This port already enables both VfsFat and VfsLfs2, so either can be used
for the filesystem, and existing systems that use FAT will still work.

Damien George ad2b3185da travis: Build GENERIC_1M board as part of esp8266 job. 2020-04-04 16:37:51 +11:00
Damien George 497ca99eb2 esp8266/makeimg.py: Print out info about RAM segments when building fw. 2020-04-04 16:30:39 +11:00
Damien George e0905e85a7 esp8266: Change from FAT to littlefs v2 as default filesystem.
This commit changes the esp8266 boards to use littlefs v2 as the
filesystem, rather than FAT.  Since the esp8266 doesn't expose the
filesystem to the PC over USB there's no strong reason to keep it as FAT.
Littlefs is smaller in code size, is more efficient in use of flash to
store data, is resilient over power failure, and using it saves about 4k of
heap RAM, which can now be used for other things.

This is a backwards incompatible change because all existing esp8266 boards
will need to update their filesystem after installing new firmware (eg
backup old files, install firmware, restore files to new filesystem).

As part of this commit the memory layout of the default board (GENERIC) has
changed.  It now allocates all 1M of memory-mapped flash to the firmware,
so the filesystem area starts at the 2M point.  This is done to allow more
frozen bytecode to be stored in the 1M of memory-mapped flash.  This
requires an esp8266 module with 2M or more of flash to work, so a new board
called GENERIC_1M is added which has the old memory-mapping (but still
changed to use littlefs for the filesystem).

In summary there are now 3 esp8266 board definitions:
- GENERIC_512K: for 512k modules, doesn't have a filesystem.
- GENERIC_1M: for 1M modules, 572k for firmware+frozen code, 396k for
  filesystem (littlefs).
- GENERIC: for 2M (or greater) modules, 968k for firmware+frozen code,
  1M+ for filesystem (littlefs), FAT driver also included in firmware for
  use on, eg, external SD cards.

Damien George df156b18e5 docs,tests: Add docs and test for uasyncio custom exc handler methods. 2020-04-04 10:47:48 +11:00
Kevin Köck 15f41c2dbf extmod/uasyncio: Add global exception handling methods.
This commit adds support for global exception handling in uasyncio
according to the CPython error handling:
https://docs.python.org/3/library/asyncio-eventloop.html#error-handling-api

This allows a program to receive exceptions from detached tasks and log
them to an appropriate location, instead of them being printed to the REPL.

The implementation preallocates a context dictionary so in case of an
exception there shouldn't be any RAM allocation.

The approach here is compatible with CPython except that in CPython the
exception handler is called once the task that threw an uncaught exception
is freed, whereas in MicroPython the exception handler is called
immediately when the exception is thrown.

Damien George b389bc0afa extmod/uasyncio: Implement Loop.stop() to stop the event loop. 2020-04-02 00:14:18 +11:00
Damien George 711dd392d3 extmod/uasyncio: Don't create a Loop instance in get_event_loop().
The event loop is (for now) just a singleton so make it so that Loop
instances are not needed.

Damien George 8fff0b0acd unix/mpthreadport: Ensure enough thread stack to detect overflow.
Following up to 5e6cee07ab, some systems (eg
FreeBSD 12.0 64-bit) will crash if the stack-overflow margin is too small.
It seems the margin of 8192 bytes (or thereabouts) is always needed.  This
commit adds this much margin if the requested stack size is too small.

Fixes issue #5824.

David Lechner 581f9135a4 tests/run-tests: Add commands to print and clean *.exp,out files.
This adds a couple of commands to the run-tests script to print the diffs
of failed tests and also to clean up the .exp and .out files after failed
tests.  (And a spelling error is fixed while we are touching nearby code.)

Travis is also updated to use these new commands, including using it for
more builds.

David Lechner 6110cd3078 tests/float: Add new lexer test to test parsing of float without prefix.
Since automatically formatting tests with black, we have lost one line of
code coverage.  This adds an explicit test to ensure we are testing the
case that is no longer covered implicitly.
2020-03-30 13:23:05 +11:00
David Lechner 3dc324d3f1 tests: Format all Python code with black, except tests in basics subdir.
This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py.  The basics/ subdirectory is excluded for now so we
aren't changing too much at once.

In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.

David Lechner 488613bca6 tests/micropython/heapalloc_fail_set.py: Remove extra trailing comma.
Unlike tuples, sets do not need trailing comma when there is only one item.

David Lechner 2461349b27 travis: Build full unix coverage build on osx job.
This should help catch more compile errors with the clang compiler.
2020-03-30 12:05:22 +11:00
David Lechner a2110bd3fc all: Fix implicit casts of float/double, and signed comparison.
These were found by buiding the unix coverage variant on macOS (so clang
compiler).  Mostly, these are fixing implicit cast of float/double to
mp_float_t which is one of those two and one mp_int_t to size_t fix for
good measure.

Using new options enabled in the uncrustify configuration.
2020-03-28 23:36:44 +11:00
Damien George b56caaf104 travis: Build NUCLEO_L073RZ instead of B_L072Z_LRWAN1 for stm32 job.
The NUCLEO_L073RZ build is slightly bigger and this MCU has only 192k flash
so this helps to catch flash overflow.
2020-03-28 13:56:16 +11:00
Damien George 83461e37d4 stm32/boards: Disable pend_throw, uheapq, utimeq on small-flash boards.
These are mainly used by the previous version of uasyncio which is now
replaced by a newer version, with built-in C module _uasyncio.  Saves about
1300 bytes of flash.

David Lechner 0608fbff29 travis: Use custom PPA to get pre-built uncrustify.
Use PPA so that we don't have to rebuild uncrustify from source, speeding

David Lechner 9418611c8a unix: Implement PEP 475 to retry syscalls failing with EINTR.
https://www.python.org/dev/peps/pep-0475/

This implements something similar to PEP 475 on the unix port, and for the
VfsPosix class.

There are a few differences from the CPython implementation:
- Since we call mp_handle_pending() between any ENITR's, additional
  functions could be called if MICROPY_ENABLE_SCHEDULER is enabled, not
  just signal handlers.
- CPython only handles signal on the main thread, so other threads will
  raise InterruptedError instead of retrying.  On MicroPython,
  mp_handle_pending() will currently raise exceptions on any thread.

A new macro MP_HAL_RETRY_SYSCALL is introduced to reduce duplicated code
and ensure that all instances behave the same.  This will also allow other
ports that use POSIX-like system calls (and use, eg, VfsPosix) to provide
their own implementation if needed.
