2021-04-30py/scheduler: Add mp_sched_exception() to schedule a pending exception.Damien George
This helper is added to properly set a pending exception, to mirror mp_sched_schedule(), which schedules a function. Signed-off-by: Damien George <damien@micropython.org>
2021-04-30py/profile: Use mp_handle_pending() to raise pending exception.Damien George
If MICROPY_ENABLE_SCHEDULER is enabled then MP_STATE_VM(sched_state) must be updated after handling the pending exception, which is done by the mp_handle_pending() function. Signed-off-by: Damien George <damien@micropython.org>
2021-04-28py/dynruntime.h: Add mp_obj_get_array() function.Damien George
Signed-off-by: Damien George <damien@micropython.org>
2021-04-27py: Add option to compile without any error messages at all.Damien George
This introduces a new option, MICROPY_ERROR_REPORTING_NONE, which completely disables all error messages. To be used in cases where MicroPython needs to fit in very limited systems. Signed-off-by: Damien George <damien@micropython.org>
2021-04-23py/objexcept: Support errno attribute on OSError exceptions.Damien George
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) See also #2407.

2021-04-12py/runtime: Make sys.modules preallocate to a configurable size.matejcik
This allows configuring the pre-allocated size of sys.modules dict, in order to prevent unwanted reallocations at run-time (3 sys-modules is really not quite enough for a larger project).
2021-04-12py/profile: Resolve name collision with STATIC unset.matejcik
When building with STATIC undefined (e.g., -DSTATIC=), there are two instances of mp_type_code that collide at link time: in profile.c and in builtinevex.c. This patch resolves the collision by renaming one of them.
2021-04-09py/py.cmake: Introduce MICROPY_INC_CORE as a list with core includes.Damien George

2021-03-31rp2: Add support for USER_C_MODULES to CMake build system.Phil Howard
The parts that are generic are added to py/ so they can be used by other ports that use CMake. py/usermod.cmake: * Creates a usermod target to hang user C/CXX modules from. * Gathers sources from user C/CXX modules and libs for QSTR scan. ports/rp2/CMakeLists.txt: * Includes py/usermod.cmake. * Links the resulting usermod library to the MicroPython target. py/mkrules.cmake: Add cxxflags to qstr.i.last custom command for CXX modules: * MICROPY_CPP_FLAGS so CXX modules will find includes. * -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h". Usage: The rp2 port can be linked against user C modules by running: make USER_C_MODULES=/path/to/module/micropython.cmake CMake will print a list of included modules.

2021-03-26py: Rename remaining object types to be of the form mp_type_xxx.Damien George
For consistency with all other object types in the core. Signed-off-by: Damien George <damien@micropython.org>
2021-03-17py/vm: For tracing use mp_printf, and print state when thread enabled.Damien George
mp_printf should be used to print the prefix because it's also used in mp_bytecode_print2 (otherwise, depending on the system, different output streams may be used). Also print the current thread state when threading is enabled to easily see which thread executes what opcode. Signed-off-by: Damien George <damien@micropython.org>
2021-03-11py/nlrx64: Fix typo in comment.Yonatan Goldschmidt

2021-02-21py/mkrules.cmake: Add MICROPY_QSTRDEFS_PORT to qstr build process.Damien George
This allows a port to specify a custom qstrdefsport.h file, the same as the QSTR_DEFS variable in a Makefile. Signed-off-by: Damien George <damien@micropython.org>
2021-02-21py/mkrules.cmake: Rename QSTR_DEFS variables to QSTRDEFS.Damien George
And also MICROPY_PY_QSTRDEFS to MICROPY_QSTRDEFS_PY. These variables are all related. Signed-off-by: Damien George <damien@micropython.org>
2021-02-16py: Expand lists in core cmake custom commands.Maureen Helm
The core cmake rules use custom commands to invoke qstr processing scripts. For the zephyr port, it's possible that list arguments to these commands may contain generator expressions, therefore we need to expand them properly. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>
2021-02-15py,extmod: Add core cmake rule files.Damien George
These allow a port to use cmake natively instead of make. Signed-off-by: Damien George <damien@micropython.org>
2021-02-08py/mpz: Fix overflow of borrow in mpn_div.Damien George
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. Signed-off-by: Damien George <damien@micropython.org>
2021-02-05py/gc: Change include of stdint.h to stddef.h.Damien George
No std-int types are used in gc.h, but size_t is which needs stddef.h. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04py: Rename WORD_MSBIT_HIGH to MP_OBJ_WORD_MSBIT_HIGH.Damien George
To make it clear it is for mp_obj_t/mp_uint_t "word" types, and to prefix this macro with MP_. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04all: Rename BYTES_PER_WORD to MP_BYTES_PER_OBJ_WORD.Damien George
The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t which is not always the same as the size of a pointer on the target architecture. So rename this config value to better reflect what it measures, and also prefix it with MP_. For uses of BYTES_PER_WORD in setting the stack limit this has been changed to sizeof(void *), because the stack usually grows with machine-word sized values (eg an nlr_buf_t has many machine words in it). Signed-off-by: Damien George <damien@micropython.org>
2021-02-04py: Rename BITS_PER_BYTE to MP_BITS_PER_BYTE.Damien George
To give this macro a standard MP_ prefix. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04py: Remove BITS_PER_WORD definition.Damien George
It's only used in one location, to test if << or >> will overflow when shifting mp_uint_t. For such a test it's clearer to use sizeof(lhs_val), which will be valid even if the type of lhs_val changes. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04py/gc: Don't include mpconfig.h and misc.h in gc.h.Xiang Xiao

2021-01-31py/makeversionhdr: Honor SOURCE_DATE_EPOCH if present.iTitou
This environment variable, if defined during the build process, indicates a fixed time that should be used in place of "now" when such a time is explicitely referenced. This allows for reproducible builds of micropython. See https://reproducible-builds.org/specs/source-date-epoch/ Signed-off-by: iTitou <moiandme@gmail.com>
2021-01-30py/persistentcode: Introduce MICROPY_PERSISTENT_CODE_SAVE_FILE option.David CARLIER
This should be enabled when the mp_raw_code_save_file function is needed. It is enabled for mpy-cross, and a check for defined(__APPLE__) is added to cover Mac M1 systems.
2021-01-30py/gc: Fix debug printing of pointer.stijn
When DEBUG_printf is the standard printf, compilers require the value for %p to be an actual pointer instead of an integer.
2021-01-30py/qstr.h: Remove QSTR_FROM_STR_STATIC macro.stijn
It practically does the same as qstr_from_str and was only used in one place, which should actually use the compile-time MP_QSTR_XXX form for consistency; qstr_from_str is for runtime strings only.

2021-01-29py/asmthumb: Add support for ARMv6M in native emitter.graham sanderson
Adds a new compile-time option MICROPY_EMIT_THUMB_ARMV7M which is enabled by default (to get existing behaviour) and which should be disabled (set to 0) when building native emitter support (@micropython.native) on ARMv6M targets.
2021-01-29py/objfun: Support fun.__globals__ attribute.Damien George
This returns a reference to the globals dict associated with the function, ie the global scope that the function was defined in. This attribute is read-only but the dict itself is modifiable, per CPython behaviour. Signed-off-by: Damien George <damien@micropython.org>

2020-12-07py/mpprint: Fix length calculation for strings with precision-modifier.Joris Peeraer
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.

2020-10-29py/py.mk: Support C++ code for user C modules.stijn
Support C++ code in .cpp files by providing CXX counterparts of the _USERMOD_ flags we have for C already. This merely enables the Makefile of user C modules to use variables specific to C++ compilation, it is still up to each port's main Makefile to also include these in the build.
2020-10-29py: Workaround clang error when building misc.h with C++ compiler.stijn
2020-10-29py/makeqstrdefs.py: Support preprocessing C++ files for QSTR generation.stijn
When SCR_QSTR contains C++ files they should be preprocessed with the same compiler flags (CXXFLAGS) as they will be compiled with, to make sure code scanned for QSTR occurrences is effectively the code used in the rest of the build. The 'split SCR_QSTR in .c and .cpp files and process each with different flags' logic isn't trivial to express in a Makefile and the existing principle for deciding which files to preprocess was already rather complicated, so the actual preprocessing is moved into makeqstrdefs.py completely.
2020-10-29py/mkrules.mk: Add target for compiling C++ files.stijn
Move the target from the ESP32 Makefile since that does what is needed already, but also include files from user C modules as is done for the C files.
2020-10-29py/makeqstrdefs.py: Process C++ files as well.stijn
Preprocessed C++ code isn't different from C code when it comes to QSTR instances so process it as well.
2020-10-29py/makeqstrdefs.py: Fix beaviour when scanning non-C preprocessed files.stijn
When process_file() is passed a preprocessed C++ file for instance it won't find any lines containing .c files and the last_fname variable remains None, so handle that gracefully.
