* py/builtinimport: Remove partially-loaded modules from sys.modules.David Grayson2023-06-05
| | | | | | | | | | | | | | | | | | | Prior to this commit, importing a module that exists but has a syntax error or some other problem that happens at import time would result in a potentially-incomplete module object getting added to sys.modules. Subsequent imports would use that object, resulting in confusing error messages that hide the root cause of the problem. This commit fixes that issue by removing the failed module from sys.modules using the new NLR callback mechanism. Note that it is still important to add the module to sys.modules while the import is happening so that we can support circular imports just like CPython does. Fixes issue #967.

* tests/import/import_pkg9.py: Add test for subpackage attribute.Jim Mussared2023-06-01
| | | | | | | | | | | When foo.bar is imported, bar is added as an attribute to foo. Previously this happened on every import, but should only happen on first import. This verifies the behavior for relative imports and overriding. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
* tests/import/builtin_ext.py: Add test for built-in module override.Jim Mussared2023-06-01
| | | | | | | | | | | This verifies the behavior: - Exact matches of built-ins bypass filesystem. - u-prefix modules can be overridden from the filesystem. - Builtin import can be forced using either u-prefix or sys.path=[].

* examples/usercmodule: Add a sub-package example.Jim Mussared2023-06-01
| | | | | | | | | | | This demonstrates how to add a sub-package in a user c module, as well as how to define the necessary qstrs and enable the feature in the build. This is used by the unix coverage build to test this feature. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
* py/objint: Allow int() to parse anything with the buffer protocol.Damien George2023-06-01
| | | | | | | | This generalises and simplifies the code and follows CPython behaviour. See similar change for floats in a07fc5b6403b9a8bf7e7cb64f857272e5346d7e2. Signed-off-by: Damien George <damien@micropython.org>
* py/obj: Accept user types in mp_obj_get_int_maybe.Damien George2023-06-01
| | | | | | | | | This is possible now that MP_UNARY_OP_INT_MAYBE exists. As a consequence mp_obj_get_int now also supports user types, which was previously possible with MP_UNARY_OP_INT but no tests existed for it. Signed-off-by: Damien George <damien@micropython.org>

* py/runtime: If inplace binop fails then try corresponding normal binop.Damien George2023-05-19
| | | | | | | | The code that handles inplace-operator to normal-binary-operator fallback is moved in this commit from py/objtype.c to py/runtime.c, making it apply to all types, not just user classes. Signed-off-by: Damien George <damien@micropython.org>
* py/objstr: Return unsupported binop instead of raising TypeError.Damien George2023-05-19

* py/objslice: Ensure slice is not hashable.David Lechner2023-05-19
| | | | | | | | As per https://bugs.python.org/issue408326, the slice object should not be hashable. Since MicroPython has an implicit fallback when the unary_op slot is empty, we need to fill this slot. Signed-off-by: David Lechner <david@pybricks.com>
* tests/run-tests.py: Ensure correct cwd for mpy tests.Jim Mussared2023-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously when using --via-mpy, the file was compiled to tests/<tmp>.mpy and then run using `micropython -m <tmp>` in the current cwd (usually tests/). This meant that an import in the test would be resolved relative to tests/. This is different to regular (non-via-mpy) tests, where we run (for example) `micropython basics/test.py` which means that an import would be resolved relative to basics/. Now --via-mpy matches the .py behavior. This is important because: a) It makes it so import tests do the right thing. b) There are directory names in tests/ that match built-in module names. Furthermore, it always ensures the cwd (for both micropython and cpython) is the test directory (e.g. basics/) rather than being left unset. This also makes it clearer inside the test that e.g. file access is relative to the Python file. Updated tests with file paths to match. This work was funded through GitHub Sponsors.

* py/compile: Remove over-eager optimisation of tuples as if condition.Damien George2023-05-03
| | | | | | | | | | | | | | | | | | | | | | | | When a tuple is the condition of an if statement, it's only possible to optimise that tuple away when it is a constant tuple (ie all its elements are constants), because if it's not constant then the elements must be evaluated in case they have side effects (even though the resulting tuple will always be "true"). The code before this change handled the empty tuple OK (because it doesn't need to be evaluated), but it discarded non-empty tuples without evaluating them, which is incorrect behaviour (as show by the updated test). This optimisation is anyway rarely applied because it's not common Python coding practice to write things like `if (): ...` and `if (1, 2): ...`, so removing this optimisation completely won't affect much code, if any. Furthermore, when MICROPY_COMP_CONST_TUPLE is enabled, constant tuples are already optimised by the parser, so expression with constant tuples like `if (): ...` and `if (1, 2): ...` will continue to be optimised properly (and so when this option is enabled the code that's deleted in this commit is actually unreachable when the if condition is a constant tuple).

* esp32,esp8266: Add support for the Espressif ESP-NOW protocol.Glenn Moloney2023-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ESP-NOW is a proprietary wireless communication protocol which supports connectionless communication between ESP32 and ESP8266 devices, using vendor specific WiFi frames. This commit adds support for this protocol through a new `espnow` module. This commit builds on original work done by @nickzoic, @shawwwn and with contributions from @zoland. Features include: - Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO. - Signal strength (RSSI) monitoring. - Core support in `_espnow` C module, extended by `espnow.py` module. - Asyncio support via `aioespnow.py` module (separate to this commit). - Docs provided at `docs/library/espnow.rst`. Methods available in espnow.ESPNow class are: - active(True/False) - config(): set rx buffer size, read timeout and tx rate - recv()/irecv()/recvinto() to read incoming messages from peers - send() to send messages to peer devices - any() to test if a message is ready to read - irq() to set callback for received messages - stats() returns transfer stats: (tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts) - add_peer(mac, ...) registers a peer before sending messages - get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt) - mod_peer(mac, ...) changes peer info parameters - get_peers() returns all peer info tuples - peers_table supports RSSI signal monitoring for received messages: {peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...} ESP8266 is a pared down version of the ESP32 ESPNow support due to code size restrictions and differences in the low-level API. See docs for details. Also included is a test suite in tests/multi_espnow. This tests basic espnow data transfer, multiple transfers, various message sizes, encrypted messages (pmk and lmk), and asyncio support. Initial work is from https://github.com/micropython/micropython/pull/4115. Initial import of code is from: https://github.com/nickzoic/micropython/tree/espnow-4115.

* extmod/vfs_posix: Do not filter '..*' in ilistdir when filtering '..'.Jeremy Rand2023-03-21
| | | | | | | | | | | When iterating over os.ilistdir(), the special directories '.' and '..' are filtered from the results.

* py/compile: Fix scope of assignment expression target in comprehensions.Damien George2023-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When := is used in a comprehension the target variable is bound to the parent scope, so it's either a global or a nonlocal. Prior to this commit that was handled by simply using the parent scope's id_info for the target variable. That's completely wrong because it uses the slot number for the parent's Python stack to store the variable, rather than the slot number for the comprehension. This will in most cases lead to incorrect behaviour or memory faults. This commit fixes the scoping of the target variable by explicitly declaring it a global or nonlocal, depending on whether the parent is the global scope or not. Then the id_info of the comprehension can be used to access the target variable. This fixes a lot of cases of using := in a comprehension.

* py/modmath: Fix two-argument math function domain check.Damien George2023-02-24
| | | | | | | | | | | | | | | | Prior to this fix, pow(1.5, inf) and pow(0.5, -inf) (among other things) would incorrectly raise a ValueError, because the result is inf with the first argument being finite. This commit fixes this by allowing the result to be infinite if the first or second (or both) argument is infinite. This fix doesn't affect the other three math functions that have two arguments: - atan2 never returns inf, so always fails isinf(ans) - copysign returns inf only if the first argument x is inf, so will never reach the isinf(y) check - fmod never returns inf, so always fails isinf(ans) Signed-off-by: Damien George <damien@micropython.org>

* extmod/modussl_mbedtls: Fix support for ioctl(MP_STREAM_POLL).Damien Tournoud2022-12-15
| | | | | | | | | | | | | | | | | During the initial handshake or subsequent renegotiation, the protocol might need to read in order to write (or conversely to write in order to read). It might be blocked from doing so by the state of the underlying socket (i.e. there is no data to read, or there is no space to write). The library indicates this condition by returning one of the errors `MBEDTLS_ERR_SSL_WANT_READ` or `MBEDTLS_ERR_SSL_WANT_WRITE`. When that happens, we need to enforce that the next poll operation only considers the direction that the library indicated. In addition, mbedtls does its own read buffering that we need to take into account while polling, and we need to save the last error between read()/write() and ioctl().
