Oliver Joos 419134bea4 tests/extmod: Add test for the precision of utime functions.
According to documentation time() has a precision of at least 1 second.
This test runs for 2.5 seconds and calls all utime functions every 100ms.
Then it checks if they returned enough different results.  All functions
with sub-second precision will return ~25 results.  This test passes with
15 results or more.  Functions that do not exist are skipped silently.

Oliver Joos dc1fd4df73 tests/extmod: Add test to try and mount a block device directly.
Mounting a bdev directly tries to auto-detect the filesystem and if none is
found an OSError(19,) should be raised.

The fourth parameter of readblocks() and writeblocks() must be optional to
support ports with MICROPY_VFS_FAT=1.  Otherwise mounting a bdev may fail
because looking for a FATFS will call readblocks() with only 3 parameters.

Damien George b505971069 extmod/uasyncio: Fix cancellation handling of wait_for.
This commit switches the roles of the helper task from a cancellation task
to a runner task, to get the correct semantics for cancellation of
wait_for.

Some uasyncio tests are now disabled for the native emitter due to issues
with native code generation of generators and yield-from.

Fixes #5797.

Damien George 309dfe39e0 extmod/uasyncio: Add Task.done() method.
This is added because task.coro==None is no longer the way to detect if a
task is finished.  Providing a (CPython compatible) function for this

Damien George ca40eb0fda extmod/uasyncio: Delay calling Loop.call_exception_handler by 1 loop.
When a tasks raises an exception which is uncaught, and no other task
await's on that task, then an error message is printed (or a user function
called) via a call to Loop.call_exception_handler.  In CPython this call is
made when the Task object is freed (eg via reference counting) because it's
at that point that it is known that the exception that was raised will
never be handled.

MicroPython does not have reference counting and the current behaviour is
to deal with uncaught exceptions as early as possible, ie as soon as they
terminate the task.  But this can be undesirable because in certain cases
a task can start and raise an exception immediately (before any await is
executed in that task's coro) and before any other task gets a chance to
await on it to catch the exception.

This commit changes the behaviour so that tasks which end due to an
uncaught exception are scheduled one more time for execution, and if they
are not await'ed on by the next scheduling loop, then the exception handler
is called (eg the exception is printed out).

Arrowana 922f81dfd1 extmod/machine_mem: Only allow integers in machine.memX subscript.
Prior to this change machine.mem32['foo'] (or using any other non-integer
subscript) could result in a fault due to 'foo' being interpreted as an
integer.  And when writing code it's hard to tell if the fault is due to a
bad subscript type, or an integer subscript that specifies an invalid
memory address.

The type of the object used in the subscript is now tested to be an
integer by using mp_obj_get_int_truncated instead of
mp_obj_int_get_truncated.  The performance hit of this change is minimal,
and machine.memX objects are more for convenience than performance (there
are many other ways to read/write memory in a faster way),

Fixes issue #6588.

Damien George 6f34800884 extmod/modurandom: Support urandom.seed() without an argument.
If a port provides MICROPY_PY_URANDOM_SEED_INIT_FUNC as a source of
randomness then this will be used when urandom.seed() is called without
an argument (or with None as the argument) to seed the pRNG.

Other related changes in this commit:
- mod_urandom___init__ is changed to call seed() without arguments, instead
  of explicitly passing in the result of MICROPY_PY_URANDOM_SEED_INIT_FUNC.
- mod_urandom___init__ will only ever seed the pRNG once (before it could
  seed it again if imported by, eg, random and then urandom).
- The Yasmarang state is moved to the BSS for builds where the state is
  guaranteed to be initialised on import of the (u)random module.

This is consistent with the other 'micro' modules and allows implementing

Damien George 2acc087880 extmod/vfs_lfs: Add mtime support to littlefs files.
This commit adds support for modification time of files on littlefs v2
filesystems, using file attributes.  For some background see issue #6114.

Features/properties of this implementation:
- Only supported on littlefs2 (not littlefs1).
- Uses littlefs2's general file attributes to store the timestamp.
- The timestamp is 64-bits and stores nanoseconds since 1970/1/1 (if the
  range to the year 2554 is not enough then additional bits can be added to
  this timestamp by adding another file attribute).
- mtime is enabled by default but can be disabled in the constructor, eg:
  uos.mount(uos.VfsLfs2(bdev, mtime=False), '/flash')
- It's fully backwards compatible, existing littlefs2 filesystems will work
  without reformatting and timestamps will be added transparently to
  existing files (once they are opened for writing).
- Files without timestamps will open correctly, and stat will just return 0
  for their timestamp.
- mtime can be disabled or enabled each mount time and timestamps will only
  be updated if mtime is enabled (otherwise they will be untouched).

Damien George 60f5b941e0 extmod/vfs_reader: Fix mp_reader_new_file to open file in "rb" mode.
mp_reader_new_file() is used to read in files for importing, either .py or
.mpy files, for the lexer and persistent code loader respectively.  In both
cases the file should be opened in raw bytes mode: the lexer handles
unicode characters itself, and .mpy files contain 8-bit bytes by nature.

Before this commit importing was working correctly because, although the
file was opened in text mode, all native filesystem implementations (POSIX,
FAT, LFS) would access the file in raw bytes mode via mp_stream_rw()
calling mp_stream_p_t.read().  So it was only an issue for non-native
filesystems, such as those implemented in Python.  For Python-based
filesystem implementations, a call to mp_stream_rw() would go via IOBase
and then to readinto() at the Python level, and readinto() is only defined
on files opened in raw bytes mode.

Thorsten von Eicken 9aa214077e extmod/modussl: Improve exception error messages.
This commit adds human readable error messages when mbedtls or axtls raise
an exception.  Currently often just an EIO error is raised so the user is
lost and can't tell whether it's a cert error, buffer overrun, connecting
to a non-ssl port, etc.  The axtls and mbedtls error raising in the ussl
module is modified to raise:

    OSError(-err_num, "error string")

For axtls a small error table of strings is added and used for the second
argument of the OSErrer.  For mbedtls the code uses mbedtls' built-in
strerror function, and if there is an out of memory condition it just
produces OSError(-err_num).  Producing the error string for mbedtls is
conditional on them being included in the mbedtls build, via
MBEDTLS_ERROR_C.

Damien George 73c58150f5 extmod/modbtree: Retain reference to underlying stream so it's not GC'd.
For ports that have a system malloc which is not garbage collected (eg
unix, esp32), the stream object for the DB must be retained separately to
prevent it from being reclaimed by the MicroPython GC (because the
berkeley-db library uses malloc to allocate the DB structure which stores
the only reference to the stream).

Although in some cases the user code will explicitly retain a reference to
the underlying stream because it needs to call close() on it, this is not
always the case, eg in cases where the DB is intended to live forever.

Eric Poulsen 01054f2092 py/objdict: Quote non-string types when used as keys in JSON output.
JSON requires that keys of objects be strings.  CPython will therefore
automatically quote simple types (NoneType, bool, int, float) when they are
used directly as keys in JSON output.  To prevent subtle bugs and emit
compliant JSON, MicroPython should at least test for such keys so they
aren't silently let through.  Then doing the actual quoting is a similar
cost to raising an exception, so that's what is implemented by this patch.

Paul Sokolovsky c76445315f extmod/modussl_axtls: Add non-blocking mode support.
It consists of:

1. "do_handhake" param (default True) to wrap_socket(). If it's False,
handshake won't be performed by wrap_socket(), as it would be done in
blocking way normally. Instead, SSL socket can be set to non-blocking mode,
and handshake would be performed before the first read/write request (by
just returning EAGAIN to these requests, while instead reading/writing/
processing handshake over the connection). Unfortunately, axTLS doesn't
really support non-blocking handshake correctly. So, while framework for
this is implemented on MicroPython's module side, in case of axTLS, it
won't work reliably.

2. Implementation of .setblocking() method. It must be called on SSL socket
for blocking vs non-blocking operation to be handled correctly (for
example, it's not enough to wrap non-blocking socket with wrap_socket()
call - resulting SSL socket won't be itself non-blocking).  Note that
.setblocking() propagates call to the underlying socket object, as
expected.

Paul Sokolovsky 6ef783527d tests/uselect_poll_basic: Add basic test for uselect.poll invariants.
This test doesn't check the actual I/O behavior, just "static" invariants
like behavior on duplicate calls or calls when I/O object is not registered
with poller.

Damien George 571295d090 tests/extmod/ujson_dump_iobase.py: Return number of bytes written.
Otherwise returning None indicates that the write would block and nothing
was actually written.  Fixes issue #3990.

Tests for separate input and output buffer (alloc-free operation) and
the same writable buffer used as input and output (inplace operation).
2018-06-27 14:56:46 +10:00
Paul Sokolovsky bf77f34819 tests/extmod/ucryptolib*: Add tests for ucryptolib module. 2018-06-27 14:56:31 +10:00
Damien George 48829cd3c6 tests/extmod: Add test for ujson.dump writing to a user IOBase object. 2018-06-18 12:35:56 +10:00

Damien George c901cc6862 tests/extmod: Add test for VFS and user-defined filesystem and files. 2018-06-12 12:29:26 +10:00
Damien George 5ef0d2ab14 tests/extmod: Remove conditional import of uos_vfs, it no longer exists.
This conditional import was only used to get the tests working on the unix
coverage build, which has now switched to use VFS by default so the uos
module alone has the required functionality.
2018-06-06 14:28:23 +10:00
Damien George 6c02da2eec tests/extmod: Add test for importing a script from a user VFS. 2018-06-06 14:28:23 +10:00

Damien George e3d11b6a6e tests/extmod/time_ms_us: Add test for calling ticks_cpu().
This is just to test that the function exists and returns some kind of
valid value.  Although this file is for testing ms/us functions, put the
ticks_cpu() test here so not to add a new test file.
2018-03-04 00:17:33 +11:00

Ayke van Laethem 7642785881 extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset.
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files.  It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files.  That seems to be a fair compromise.
2018-01-31 17:33:07 +11:00
Damien George d35c6ffc84 tests/extmod: Add some uctypes tests to improve coverage of that module. 2017-12-19 16:48:41 +11:00

Petr Viktorin 34247465c3 extmod/modframebuf: Add 2-bit color format (GS2_HMSB).
This format is used in 2-color LED matrices and in e-ink displays like
SSD1606.
2017-12-14 17:13:02 +11:00

These now should be caught properly and lead to RuntimeError instead of
crash.
