* extmod/vfs: Guard mutating fs functions with MICROPY_VFS_WRITABLE.Damien George2024-12-20
| | | | | | | Enabled by default. Useful for ports that need the VFS but don't have any writable filesystems. Signed-off-by: Damien George <damien@micropython.org>
* py/mkrules.mk: Use partial clone for submodules if available.Andrew Leech2024-12-10
| | | | | | | | | | | | | | | MicroPython relies on a number of submodules for third party and chip vendor libraries. Users need to check these out before building their desired ports and Github Actions CI here needs to clone them all multiple times for every build. Many of these are getting significantly larger over time, slowing down usage and consuming more disk space. Newer versions of git have features to avoid pulling all historic / blob data which can have a significant impact of total data use. This commit uses a standard feature of git to do a partial clone, with automatic fallback to previous behavior on error. Signed-off-by: Andrew Leech <andrew.leech@planetinnovation.com.au>
* py/emitglue: Fix clear cache builtin warning on Clang for AArch32.Alessandro Gatti2024-12-10
| | | | | | | | | This commit fixes a warning occurring on Clang when calling `__builtin___clear_cache` with non-void pointers for its start and end memory area locations. The code now uses a char pointer for the end location, and it still builds without warnings on GCC. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/misc: Fix msvc and C++ compatibility.stijn2024-12-10
| | | | | | | Use an explicit cast to suppress the implicit conversion which started popping up in recent compiler versions (and wasn't there yet in 07bf3179). Signed-off-by: stijn <stijn@ignitron.net>
* esp32: Pass V=1 or BUILD_VERBOSE through to idf.py when building.Angus Gratton2024-12-10
| | | | | | | | | Allows verbose build to work the same on esp32 port as other ports. To minimise copy/paste, split the BUILD_VERBOSE section of mkenv.mk out to its own verbose.mk and include this in the port Makefile. Signed-off-by: Angus Gratton <angus@redyak.com.au>
* py/objfloat: Workaround non-constant NAN definition on Windows MSVC.Angus Gratton2024-11-28
| | | | | | | | | | | Recent MSVC versions have changed the definition of NAN to a non-constant expression! This is a bug, C standard says it should be a constant. Good explanation and workaround at: https://stackoverflow.com/a/79199887 This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>

* py/objdeque: Fix buffer overflow in deque_subscr.Jan Sturm2024-11-04
| | | | | | | | | | | | In `deque_subscr()`, if `index_val` equals `self->alloc`, the index correction `index_val -= self->alloc` does not execute, leading to an out-of-bounds access in `self->items[index_val]`. The fix in this commit ensures that the index correction is applied whenever `index_val >= self->alloc`, preventing access beyond the allocated buffer size.

* pic16bit: Make it build with recent XC16 versions.Alessandro Gatti2024-10-30
| | | | | | | The PIC16 port didn't catch up with the other ports, so it required a bit of work to make it build with the latest version of XC16. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>

* extmod/modtls_mbedtls: Add a thread-global ptr for current SSL context.iabdalkader2024-10-25
| | | | | | | This is necessary for mbedTLS callbacks that do not carry any user state, so those callbacks can be customised per SSL context. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
* py/objtype: Don't delegate lookup of descriptor methods to __getattr__.Damien George2024-10-16
| | | | | | | | When descriptors are enabled, lookup of the `__get__`, `__set__` and `__delete__` descriptor methods should not be delegated to `__getattr__`. That follows CPython behaviour. Signed-off-by: Damien George <damien@micropython.org>
* py/usermod.cmake: Check target exists in usermod_gather_sources.Phil Howard2024-10-15
| | | | | | | Check a target exists before accessing properties. Otherwise usermod_gather_sources would recurse into garbage property names and break. Signed-off-by: Phil Howard <phil@gadgetoid.com>
* py/objtype: Allow passing keyword arguments to native base __init__.stijn2024-10-07
| | | | | | | | | | | | | | | Allowing passing keyword arguments to a native base's __init__, i.e. `make_new` in the C code. Previously only positional arguments were allowed. The main trade-off in this commit is that every call to the native base's `make_new` is now going to be preceded by a call to `mp_map_init_fixed_table` even though most of what that does is unused and instead it merely serves as a way to pass the number of keyword arguments. Fixes issue #15465. Signed-off-by: stijn <stijn@ignitron.net>
* py/nlrrv64: Add RISC-V RV64I NLR implementation.Alessandro Gatti2024-10-03
| | | | | | Add custom NLR support for 64 bits RISC-V RV64I targets. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/parse: Remove old esp32 compiler workaround.Alessandro Gatti2024-09-27
| | | | | | | | | | | | The ESP32 port contains a workaround to avoid having a certain function in `py/parse.c` being generated incorrectly. The compiler in question is not part of any currently supported version of ESP-IDF anymore, and the problem inside the compiler (well, assembler in this case) has been corrected a few years ago. This commit removes all traces of that workaround from the source tree. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/mpz: Skip separators when running out of digits to print.Alessandro Gatti2024-09-26
| | | | | | | | | | This commit fixes the addition of a stray separator before the number when printing an MPZ-backed integer and the first group is three digits long. This fixes #8984. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>

* py/objringio: Add micropython.RingIO() interface for general use.Andrew Leech2024-09-19
| | | | | | | | | | | | This commit adds a new `RingIO` type which exposes the internal ring-buffer code for general use in Python programs. It has the stream interface making it similar to `StringIO` and `BytesIO`, except `RingIO` has a fixed buffer size and is automatically safe when reads and writes are in different threads or an IRQ. This new type is enabled at the "extra features" ROM level. Signed-off-by: Andrew Leech <andrew.leech@planetinnovation.com.au>
* py/scheduler: Only run callbacks on the main thread if GIL is disabled.Angus Gratton2024-09-19
| | | | | | | | | | Otherwise it's very difficult to reason about thread safety in a scheduler callback, as it can run at any time on any thread - including racing against any bytecode operation on any thread. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>

* py/mkrules.mk: Fix 'make submodules' when building out-of-tree.Christian Walther2024-08-26
| | | | | | | | | | When MicroPython is used as a submodule and built from the containing project, e.g. for the embed port, `make submodules` fails because it goes looking for the sub-sub-module paths in the outer repository instead of in the micropython repository. Fix this by invoking git inside the micropython submodule. Signed-off-by: Christian Walther <cwalther@gmx.ch>
* py/asmrv32: Use REG_TEMP2 whenever possible.Alessandro Gatti2024-08-19
| | | | | | | | The RV32 emitter used an additional temporary register, as certain code sequences required extra storage. This commit removes its usage in all but one case, using REG_TEMP2 instead. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/asmrv32: Emit C.LW opcodes only when necessary.Alessandro Gatti2024-08-19
| | | | | | | | | | | The RV32 emitter sometimes generated short load opcodes even when it was not supposed to. This commit fixes an off-by-one error in its offset eligibility range calculation and corrects one case of offset calculation, operating on the raw label index number rather than its effective offset in the stack (C.LW assumes all loads are word-aligned). Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/asmrv32: Fix short/long jumps scheduling.Alessandro Gatti2024-08-19
| | | | | | | | | | The RV32 emitter always scheduled short jumps even outside the emit compiler pass. Running the full test suite through the native emitter instead of just the tests that depend on the emitter at runtime (as in, `micropython/native_*` and `micropython/viper_* tests`) uncovered more places where the invalid behaviour was still present. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* py/objstr: Skip whitespace in bytes.fromhex().Glenn Moloney2024-08-19
| | | | | | | | | Skip whitespace characters between pairs of hex numbers. This makes `bytes.fromhex()` compatible with cpython. Includes simple test in `tests/basic/builtin_str_hex.py`. Signed-off-by: Glenn Moloney <glenn.moloney@gmail.com>
* py: Add new cstack API for stack checking, with limit margin macro.Angus Gratton2024-08-14
| | | | | | | | | | | | | | | | | | | | Currently the stack limit margin is hard-coded in each port's call to `mp_stack_set_limit()`, but on threaded ports it's fiddlier and can lead to bugs (such as incorrect thread stack margin on esp32). This commit provides a new API to initialise the C Stack in one function call, with a config macro to set the margin. Where possible the new call is inlined to reduce code size in thread-free ports. Intended replacement for `MP_TASK_STACK_LIMIT_MARGIN` on esp32. The previous `stackctrl.h` API is still present and unmodified apart from a deprecation comment. However it's not available when the `MICROPY_PREVIEW_VERSION_2` macro is set. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
* py/obj: Remove the legacy object API for version 2.Angus Gratton2024-08-14
| | | | | | | | | These were changed in v1.11 (2019). Prepare to remove the compatibility macros as part of V2 changes. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
* py/modmath: Add option to work around -inf bug in a port's tgamma.Angus Gratton2024-08-07
| | | | | | | | | This is needed for a workaround on esp32 port (in child commit), which produces incorrect results otherwise. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
* py/emitnative: Fix case of clobbered REG_TEMP0 when loading const obj.Damien George2024-08-07
| | | | | | | | | | | | | | | | The `emit_load_reg_with_object()` helper function will clobber `REG_TEMP0`. This is currently OK on architectures where `REG_RET` and `REG_TEMP0` are the same (all architectures except RV32), because all callers of `emit_load_reg_with_object()` use either `REG_RET` or `REG_TEMP0` as the destination register. But on RV32 these registers are different and so when `REG_RET` is the destination, `REG_TEMP0` is clobbered, leading to incorrectly generated machine code. This commit fixes the issue simply by using `REG_TEMP0` as the destination register for all uses of `emit_load_reg_with_object()`, and adds a comment to make sure the caller of this function is careful.

* py/py.mk: Add SRC_USERMOD_LIB_ASM to include assembly files.George Hopkins2024-08-01
| | | | | | | | Introduce SRC_USERMOD_LIB_ASM to allow users to include assembly files as part of their user modules. It could be used to include optimized functions or outputs of other programming languages. Signed-off-by: George Hopkins <george-hopkins@null.net>

* py/misc: Fix msvc and C++ compatibility.stijn2024-07-25
| | | | | | | | | | | Use explicit casts to suppress warnings about implicit conversions, add a workaround for constant expression conditional, and make functions static inline (as is done in the rest of the codebase) to suppress 'warning C4505: unreferenced function with internal linkage has been removed'. (Follow up to fix commit 908ab1ceca15ee6fd0ef82ca4cba770a3ec41894) Signed-off-by: stijn <stijn@ignitron.net>
* py/objtype: Validate super() arguments.stijn2024-07-25
| | | | | | | | | | This fixes various null dereferencing and out-of-bounds access because super_attr assumes the held obj is effectively an object of the held type, which is now verified. Fixes issue #12830. Signed-off-by: stijn <stijn@ignitron.net>
* py/objtype: Avoid crash on calling members of uninitialized native type.Laurens Valk2024-07-25
| | | | | | | | | | | | | When subclassing a native type, calling native members in `__init__` before `super().__init__()` has been called could cause a crash. In this situation, `self` in `mp_convert_member_lookup` is the `native_base_init_wrapper_obj`. The check added in this commit ensures that an `AttributeError` is raised before this happens, which is consistent with other failed lookups. Also fix a typo in a related comment.

* extmod/modmachine: Use sys.exit as implementation of machine.soft_reset.Damien George2024-07-20

* py/gc: Remove commented-out functions.Damien George2024-07-19
| | | | | | | These are old, unused, and most of them no longer compile. The `gc_test()` function is superseded by the test suite. Signed-off-by: Damien George <damien@micropython.org>
* py/sequence: Remove unused len argument from mp_seq_extract_slice.Damien George2024-07-18
| | | | | | | Also put this function inside the `MICROPY_PY_BUILTINS_SLICE` guard, because it's only usable when that option is enabled. Signed-off-by: Damien George <damien@micropython.org>

* py: Remove 5 TODOs in emitbc, objrange and repl.Damien George2024-07-18
| | | | | | | | | | | | | | | | These TODOs don't need to be done: - Calling functions with keyword arguments is less common than without them, so adding an extra byte overhead to all calls regardless of whether they use keywords or not would overall increase generated bytecode size. - Restricting `range` objects to machine-sized ints has been adequate for a long time now, so no need to change that and make it more complicated and slower. - Printing spaces in tab completion does not need to be optimised. Signed-off-by: Damien George <damien@micropython.org>
* extmod/machine_spi: Support firstbit=LSB for machine.SoftSPI.robert-hh2024-07-12
| | | | | | | | | | | | | | | | Being able to send data out in LSB format can be useful, and having support in the low-level driver is much better than requiring Python code to reorder the bits before sending them / after receiving them. In particular if the hardware does not support the LSB format (eg RP2040) then one needs to use the SoftSPI in LSB mode. For this change a default definition of `MICROPY_PY_MACHINE_SPI_MSB/_LSB` was added to `py/mpconfig.h`, making them available to all ports. The identical defines in `esp32/mpconfigport.h` were deleted. Resolves issues #5340, #11404. Signed-off-by: robert-hh <robert@hammelrath.com>
* extmod/modmachine: Allow more than one argument to machine.freq().robert-hh2024-07-11
| | | | | | | | | | | The limit is set by a `MICROPY_PY_MACHINE_FREQ_NUM_ARGS_MAX` define, which defaults to 1 and is set for stm32 to 4. For stm32 this fixes a regression introduced in commit e1ec6af654b1c5c4a973b6c6b029ee68bb92eb89 where the maximum number of arguments was changed from 4 to 1.

* all: Use new mp_obj_new_str_from_cstr() function.Jon Foster2024-07-04
| | | | | | | Use new function mp_obj_new_str_from_cstr() where appropriate. It simplifies the code, and makes it smaller too. Signed-off-by: Jon Foster <jon@jon-foster.co.uk>
* py/objstr: Add new mp_obj_new_str_from_cstr() helper function.Jon Foster2024-07-04
| | | | | | | | | | | | | | | There were lots of places where this pattern was duplicated, to convert a standard C string to a MicroPython string: x = mp_obj_new_str(s, strlen(s)); This commit provides a simpler method that removes this code duplication: x = mp_obj_new_str_from_cstr(s); This gives clearer, and probably smaller, code.
