* py/emitinlinerv32: Add inline assembler support for RV32.Alessandro Gatti2025-01-02
| | | | | | | | | | | | This commit adds support for writing inline assembler functions when targeting a RV32IMC processor. Given that this takes up a bit of rodata space due to its large instruction decoding table and its extensive error messages, it is enabled by default only on offline targets such as mpy-cross and the qemu port.

* py/misc: Add a popcount(uint32_t) implementation.Alessandro Gatti2025-01-01
| | | | | | | | | | This makes the existing popcount(uint32_t) implementation found in the RV32 emitter available to the rest of the codebase. This version of popcount will use intrinsic or builtin implementations if they are available, falling back to a generic implementation if that is not the case.

* py/persistentcode: Add support for loading .mpy files from a ROM reader.Damien George2024-12-23
| | | | | | | | This adds an optimisation for loading .mpy files from a reader that points to ROM. In such a case qstr, str and bytes data, along with bytecode, are all referenced in-place in ROM. Signed-off-by: Damien George <damien@micropython.org>
* py/reader: Provide mp_reader_try_read_rom() function.Damien George2024-12-23
| | | | | | This allows accessing data directly in ROM if the reader supports it. Signed-off-by: Damien George <damien@micropython.org>
* py/qstr: Add qstr_from_strn_static() helper function.Damien George2024-12-23
| | | | | | | Allows an interned string to reference static/ROM data, instead of allocating it on the GC heap. Signed-off-by: Damien George <damien@micropython.org>
* extmod/vfs_rom: Add VfsRom filesystem object.Damien George2024-12-23
| | | | | | | | | | | | | | | | This commit defines a new ROMFS filesystem for storing read-only files that can be memory mapped, and a new VfsRom driver. Files opened from this filesystem support the buffer protocol. This allows naturally getting the memory-mapped address of the file using: - memoryview(file) - uctypes.addressof(file) Furthermore, if these files are .mpy files then their content can be referenced in-place when importing. Such imports take up a lot less RAM than importing from a normal filesystem. This is essentially dynamically frozen .mpy files, building on the revamped v6 .mpy file format.

* py/dynruntime.mk: Delete compiled module file on clean.Alessandro Gatti2024-12-23
| | | | | | | This commit adds the compiled native module file to the list of files to remove when `make clean` is issued in a native module source directory. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* tools/mpy_ld.py: Add native modules support for RV32 code.Alessandro Gatti2024-12-23
| | | | | | | | This commit adds support for RV32IMC native modules, as in embedding native code into a self-contained MPY module and and make its exported functions available to the MicroPython environment. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
* 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

* 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.

* 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.

* py/objstr: Skip whitespace in bytes.fromhex().Glenn Moloney2024-08-19

* 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

* py/modmath: Add option to work around -inf bug in a port's tgamma.Angus Gratton2024-08-07

* 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/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.
