Damien George 9e29217c73 unix/modffi: Use a union for passing/returning FFI values.
This fixes a bug where double arguments on a 32-bit architecture would not
be passed correctly because they only had 4 bytes of storage (not 8).  It
also fixes a compiler warning/error in return_ffi_value on certian
architectures: array subscript 'double[0]' is partly outside array bounds
of 'ffi_arg[1]' {aka 'long unsigned int[1]'}.

Fixes issue #7064.

Damien George 3c4bfd1dec py/objexcept: Support errno attribute on OSError exceptions.
This commit adds the errno attribute to exceptions, so code can retrieve
errno codes from an OSError using exc.errno.

The implementation here simply lets `errno` (and the existing `value`)
attributes work on any exception instance (they both alias args[0]).  This
is for efficiency and to keep code size down.  The pros and cons of this
are:

Pros:
- more compatible with CPython, less difference to document and learn
- OSError().errno will correctly return None, whereas the current way of
  doing it via OSError().args[0] will raise an IndexError
- it reduces code size on most bare-metal ports (because they already have
  the errno qstr)
- for Python code that uses exc.errno the generated bytecode is 2 bytes
  smaller and more efficient to execute (compared with exc.args[0]); so
  bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute,
  and bytecode that is frozen saves 2 bytes flash/ROM for each use
- it's easier/shorter to type, and saves 2 bytes of space in .py files that
  use it (for each use)

Cons:
- increases code size by 4-8 bytes on minimal ports that don't already have
  the `errno` qstr
- all exceptions now have .errno and .value attributes (a cpydiff test is
  added to address this)

Damien George 8459f538eb tests/feature_check: Check for lack of pass result rather than failure.
Commit cb68a5741a broke automatic Python
feature detection when running tests, because some detection relied on a
crash of a feature script returning exactly b"CRASH".

of a known pass result, rather than an exact failure result.

stijn a66286f3a0 unix: Improve command line argument processing.
Per CPython everything which comes after the command, module or file
argument is not an option for the interpreter itself.  Hence the processing
of options should stop when encountering those, and the remainder be passed
as sys.argv.  Note the latter was already the case for a module or file but
not for a command.

This fixes issues like 'micropython myfile.py -h' showing the help and
exiting instead of passing '-h' as sys.argv[1], likewise for
'-X <something>' being treated as a special option no matter where it
occurs on the command line.

Thorsten von Eicken c10d431819 esp32: Add basic support for Non-Volatile-Storage in esp32 module.
This commit implements basic NVS support for the esp32.  It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace.  The initial support provided is only for signed 32-bit integers
and binary blobs.  It's easy (albeit a bit tedious) to add support for
more types.

Damien George 0a59938574 py/mpz: Fix overflow of borrow in mpn_div.
For certain operands to mpn_div, the existing code path for
`DIG_SIZE == MPZ_DBL_DIG_SIZE / 2` had a bug in it where borrow could still
overflow in the `(x >= *n || *n - x <= borrow)` branch, ie
`borrow + x - (mpz_dbl_dig_t)*n` overflows the borrow variable.  In such
cases the subsequent right-shift of borrow would not bring in the overflow
bit, leading to an error in the result.  An example division that had
overflow when MPZ_DIG_SIZE = 16 is `(2 ** 48 - 1) ** 2 // (2 ** 48 - 1)`.

This is fixed in this commit by simplifying the code and handling the low
digits of borrow first, and then the upper bits (to shift down) separately.
There is no longer a distinction between `DIG_SIZE < MPZ_DBL_DIG_SIZE / 2`
and `DIG_SIZE == MPZ_DBL_DIG_SIZE / 2`.

This commit also simplifies the second part of the calculation so that
borrow does not need to be negated (instead the code just works knowing
that borrow is negative and using + instead of - in calculations involving
borrow).

Fixes #6777.

stijn 108183fcc0 tests/misc/sys_settrace: Make test output independent of invoked path.
The original logic of reducing a full path to a relative one assumes
"tests/misc" is in the filename which is limited in usage: it never works
for CPython on Windows since that will use a backslash as path separator,
and also won't work when the filename is a path not relative to the tests
directory which happens for example in the common case of running
"./run-tests -d misc".

Fix all cases by printing only the bare filename, which requires them all
to start with sys_settrace_ hence the renaming.

Joris Peeraer 5020b14d54 py/mpprint: Fix length calculation for strings with precision-modifier.
Two issues are tackled:

1. The calculation of the correct length to print is fixed to treat the
   precision as a maximum length instead as the exact length.
   This is done for both qstr (%q) and for regular str (%s).

2. Fix the incorrect use of mp_printf("%.*s") to mp_print_strn().

   Because of the fix of above issue, some testcases that would print
   an embedded null-byte (^@ in test-output) would now fail.
   The bug here is that "%s" was used to print null-bytes. Instead,
   mp_print_strn is used to make sure all bytes are outputted and the
   exact length is respected.

Test-cases are added for both %s and %q with a combination of precision
and padding specifiers.

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),

stijn 405893afc6 tests/run-tests: Use absolute paths where possible.
Replace some usages of paths relative to the current working directory
with absolute paths relative to the tests directory.

Fixes and resulting changes:
- default values of MICROPYTHON and MPYCROSS are absolute paths and
  always correct
- likewise, the correct full paths for tools and extmod directories
  are appended to sys.path
- printing/cleaning failures works properly since it expects the .exp
  and .out files in the tests directory which is also where they
  are written to now, plus no more need for changing directories

This fixes #5872 and allows running custom tests which use run-tests
without having to cd to the tests directory first, and the test output
still is in the tests/ directory instead of the current working directory.

Discovery of tests and all skip test logic based on paths relative to
the current working directory remains unchanged which essentially means
that for running most of MicroPython's own tests, run-tests must still
be ran from within it's directory, so document that.

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.

Damien George 9883d8e818 py/persistentcode: Maintain root ptr list of imported native .mpy code.
On ports where normal heap memory can contain executable code (eg ARM-based
ports such as stm32), native code loaded from an .mpy file may be reclaimed
by the GC because there's no reference to the very start of the native
machine code block that is reachable from root pointers (only pointers to
internal parts of the machine code block are reachable, but that doesn't
help the GC find the memory).

This commit fixes this issue by maintaining an explicit list of root
pointers pointing to native code that is loaded from an .mpy file.  This
is not needed for all ports so is selectable by the new configuration
option MICROPY_PERSISTENT_CODE_TRACK_RELOC_CODE.  It's enabled by default
if a port does not specify any special functions to allocate or commit
executable memory.

A test is included to test that native code loaded from an .mpy file does
not get reclaimed by the GC.

Jonathan Hogg 37e1b5c891 py/compile: Don't await __aiter__ special method in async-for.
MicroPython's original implementation of __aiter__ was correct for an
earlier (provisional) version of PEP492 (CPython 3.5), where __aiter__ was
an async-def function.  But that changed in the final version of PEP492 (in
CPython 3.5.2) where the function was changed to a normal one.  See
https://www.python.org/dev/peps/pep-0492/#why-aiter-does-not-return-an-awaitable
See also the note at the end of this subsection in the docs:
https://docs.python.org/3.5/reference/datamodel.html#asynchronous-iterators
And for completeness the BPO: https://bugs.python.org/issue27243

To be consistent with the Python spec as it stands today (and now that
PEP492 is final) this commit changes MicroPython's behaviour to match
CPython:  __aiter__ should return an async-iterable object, but is not
itself awaitable.

The relevant tests are updated to match.

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.

Jim Mussared e152d0c197 extmod/btstack: Schedule notify/indicate/write ops for bg completion.
The goal of this commit is to allow using ble.gatts_notify() at any time,
even if the stack is not ready to send the notification right now.  It also
addresses the same issue for ble.gatts_indicate() and ble.gattc_write()
(without response).  In addition this commit fixes the case where the
buffer passed to write-with-response wasn't copied, meaning it could be
modified by the caller, affecting the in-progress write.

The changes are:

- gatts_notify/indicate will now run in the background if the ACL buffer is
  currently full, meaning that notify/indicate can be called at any time.

- gattc_write(mode=0) (no response) will now allow for one outstanding
  write.

- gattc_write(mode=1) (with response) will now copy the buffer so that it
  can't be modified by the caller while the write is in progress.

All four paths also now track the buffer while the operation is in
progress, which prevents the GC free'ing the buffer while it's still
needed.

Damien George 332d83343f py: Rework mp_convert_member_lookup to properly handle built-ins.
This commit fixes lookups of class members to make it so that built-in
functions that are used as methods/functions of a class work correctly.

The mp_convert_member_lookup() function is pretty much completely changed
by this commit, but for the most part it's just reorganised and the
indenting changed.  The functional changes are:

- staticmethod and classmethod checks moved to later in the if-logic,
  because they are less common and so should be checked after the more
  common cases.

- The explicit mp_obj_is_type(member, &mp_type_type) check is removed
  because it's now subsumed by other, more general tests in this function.

- MP_TYPE_FLAG_BINDS_SELF and MP_TYPE_FLAG_BUILTIN_FUN type flags added to
  make the checks in this function much simpler (now they just test this
  bit in type->flags).

- An extra check is made for mp_obj_is_instance_type(type) to fix lookup of
  built-in functions.

robert 0f83ef395c extmod/vfs_lfsx: Fix rename to respect cur dir for new path.
If the new name start with '/', cur_dir is not prepened any more, so that
the current working directory is respected.  And extend the test cases for
rename to cover this functionality.

robert d3ea28d04a extmod/vfs_lfsx: Normalize path name in chdir.
This change scans for '.', '..' and multiple '/' and normalizes the new
path name.  If the resulting path does not exist, an error is raised.
Non-existing interim path elements are ignored if they are removed during
normalization.

robert a5ea4b9f3f extmod/vfs_lfsx: Fix path handling in uos.stat() to consider cur dir.
This fixes the bug, that stat(filename) would not consider the current
working directory.  So if e.g. the cwd is "lib", then stat("main.py") would
return the info for "/main.py" instead of "/lib/main.py".

  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ValueError: size not valid: 32768 bytes

So increase the CPython value in the test to 512k so it runs on more
systems (on modern Linux the default stack size is usually 8MB).

Damien George 4ede703687 py/parse: Support constant folding of power operator for integers.
Constant expression like "2 ** 3" will now be folded, and the special form

now a constant.

Thorsten von Eicken 952ff8a8ea esp32: Improve support for OTA updates.
This commit adds several small items to improve the support for OTA
updates on an esp32:

- a partition table for 4MB flash modules that has two OTA partitions ready
  to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
  automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
  signal that the boot is successful and should not be rolled back at the
  next reset
- an automated test for doing an OTA update
- documentation updates

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.

Fixes issue #5940.

Thorsten von Eicken 1ae7e0e561 esp32: Consolidate check_esp_err functions and add IDF error string.
This commit consolidates a number of check_esp_err functions that check
whether an ESP-IDF return code is OK and raises an exception if not.  The
exception raised is an OSError with the error code as the first argument
(negative if it's ESP-IDF specific) and the ESP-IDF error string as the
second argument.

This commit also fixes esp32.Partition.set_boot to use check_esp_err, and
uses that function for a unit test.

This commit adds an idf_heap_info(capabilities) method to the esp32 module
which returns info about the ESP-IDF heaps.  It's useful to get a bit of a
picture of what's going on when code fails because ESP-IDF can't allocate
memory anymore.  Includes documentation and a test.

stijn f31f9a8b70 py/objint: Do not use fpclassify.
For combinations of certain versions of glibc and gcc the definition of
fpclassify always takes float as argument instead of adapting itself to
float/double/long double as required by the C99 standard.  At the time of
writing this happens for instance for glibc 2.27 with gcc 7.5.0 when
compiled with -Os and glibc 3.0.7 with gcc 9.3.0.  When calling fpclassify
with double as argument, as in objint.c, this results in an implicit
narrowing conversion which is not really correct plus results in a warning
when compiled with -Wfloat-conversion.  So fix this by spelling out the
logic manually.

stijn 7fb9edf436 tests/float: Fix cmath_fun_special for MICROPY_FLOAT_IMPL_FLOAT.
When the unix and windows ports use MICROPY_FLOAT_IMPL_FLOAT instead of
MICROPY_FLOAT_IMPL_DOUBLE, the test output has for example
complex(-0.15052, 0.34109) instead of the expected
complex(-0.15051, 0.34109).

Use one decimal place less for the output printing to fix this.

Damien George dd0bc26e65 extmod/modbluetooth: Change scan result's "connectable" to "adv_type".
This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.

Damien George df9a949891 tests/run-multitests.py: Add new test runner for multiple Py instances.
This commit adds a test runner and initial test scripts which run multiple
Python/MicroPython instances (eg executables, target boards) in parallel.
This is useful for testing, eg, network and Bluetooth functionality.

Each test file has a set of functions called instanceX(), where X ranges
from 0 up to the maximum number of instances that are needed, N-1.  Then
run-multitests.py will execute this script on N separate instances (eg
micropython executables, or attached boards via pyboard.py) at the same
time, synchronising their start in the right order, possibly passing IP
address (or other address like bluetooth MAC) from the "server" instance to
the "client" instances so they can connect to each other.  It then runs
them to completion, collects the output, and then tests against what
CPython gives (or what's in a provided .py.exp file).

The tests will be run using the standard unix executable for all instances
by default, eg:

    $ ./run-multitests.py multi_net/*.py

Or they can be run with a board and unix executable via:

    $ ./run-multitests.py --instance pyb:/dev/ttyACM0 --instance exec:micropython multi_net/*.py

Nicko van Someren 3aab54bf43 py: Support non-boolean results for equality and inequality tests.
This commit implements a more complete replication of CPython's behaviour
for equality and inequality testing of objects.  This addresses the issues
discussed in #5382 and a few other inconsistencies.  Improvements over the
old code include:

- Support for returning non-boolean results from comparisons (as used by
  numpy and others).
- Support for non-reflexive equality tests.
- Preferential use of __ne__ methods and MP_BINARY_OP_NOT_EQUAL binary
  operators for inequality tests, when available.
- Fallback to op2 == op1 or op2 != op1 when op1 does not implement the
  (in)equality operators.

The scheme here makes use of a new flag, MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST,
in the flags word of mp_obj_type_t to indicate if various shortcuts can or
cannot be used when performing equality and inequality tests.  Currently
four built-in classes have the flag set: float and complex are
non-reflexive (since nan != nan) while bytearray and frozenszet instances
can equal other builtin class instances (bytes and set respectively).  The
flag is also set for any new class defined by the user.

This commit also includes a more comprehensive set of tests for the
behaviour of (in)equality operators implemented in special methods.

Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

Damien George 80df377e95 py/modsys: Report .mpy version in sys.implementation.
This commit adds a sys.implementation.mpy entry when the system supports
importing .mpy files.  This entry is a 16-bit integer which encodes two
bytes of information from the header of .mpy files that are supported by
the system being run: the second and third bytes, .mpy version, and flags
and native architecture.  This allows determining the supported .mpy file
dynamically by code, and also for the user to find it out by inspecting
this value.  It's further possible to dynamically detect if the system
supports importing .mpy files by `hasattr(sys.implementation, 'mpy')`.

Damien George 23f0691fdd py/persistentcode: Make .mpy more compact with qstr directly in prelude.
Instead of encoding 4 zero bytes as placeholders for the simple_name and
source_file qstrs, and storing the qstrs after the bytecode, store the
qstrs at the location of these 4 bytes.  This saves 4 bytes per bytecode
function stored in a .mpy file (for example lcd160cr.mpy drops by 232
bytes, 4x 58 functions).  And resulting code size is slightly reduced on
ports that use this feature.

Damien George 809d89c794 py/runtime: Fix PEP479 behaviour throwing StopIteration into yield from.
Commit 3f6ffe059f implemented PEP479 but did
not catch the case fixed in this commit.  Found by coverage analysis, that
the VM had uncovered code.

Damien George 82c494a97e py/vm: Fix handling of unwind jump out of active finally.
Prior to this commit, when unwinding through an active finally the stack
was not being correctly popped/folded, which resulting in the VM crashing
for complicated unwinding of nested finallys.

This should be fixed with this commit, and more tests for return/break/
continue within a finally have been added to exercise this.
2019-10-04 23:01:29 +10:00
Petr Viktorin 25a9bccdee py/compile: Disallow 'import *' outside module level.
This check follows CPython's behaviour, because 'import *' always populates
the globals with the imported names, not locals.

Since it's safe to do this (doesn't lead to a crash or undefined behaviour)
the check is only enabled for MICROPY_CPYTHON_COMPAT.

Fixes issue #5121.
