2022-10-11py/modsys: Add support for sys.executable.Jim Mussared
Only intended to be used on Unix and other "OS" ports. Matches CPython. This should give the absolute path to the executing binary. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com> Signed-off-by: Damien George <damien@micropython.org>
2022-07-18py/modsys: Use MP_REGISTER_ROOT_POINTER().David Lechner
This uses MP_REGISTER_ROOT_POINTER() to register cur_exception, sys_exitfunc, mp_sys_path_obj, mp_sys_argv_obj and sys_mutable instead of using a conditional inside of mp_state_vm_t. Signed-off-by: David Lechner <david@pybricks.com>
2022-06-02all: Remove third argument to MP_REGISTER_MODULE.Damien George
It's no longer needed because this macro is now processed after preprocessing the source code via cpp (in the qstr extraction stage), which means unused MP_REGISTER_MODULE's are filtered out by the preprocessor. Signed-off-by: Damien George <damien@micropython.org>
2022-05-18py: Make builtin modules use MP_REGISTER_MODULE.Jim Mussared
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
2022-04-28py/modsys: Introduce sys.implementation._machine constant.Damien George
This contains a string useful for identifying the underlying machine. This string is kept consistent with the second part of the REPL banner via the new config option MICROPY_BANNER_MACHINE. This makes os.uname() more or less redundant, as all the information in os.uname() is now available in the sys module. Signed-off-by: Damien George <damien@micropython.org>
2022-04-28py/modsys: Rename sys.implementation.mpy to sys.implementation._mpy.Damien George
Per CPython docs, non-standard attributes must begin with an underscore. Signed-off-by: Damien George <damien@micropython.org>
2022-04-28py/modsys: Append MicroPython git version and build date to sys.version.Damien George
This commit adds the git hash and build date to sys.version. This is allowed according to CPython docs, and is what PyPy does. The docs state: A string containing the version number of the Python interpreter plus additional information on the build number and compiler used. Eg on CPython: Python 3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.version '3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0]' and PyPy: Python 2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30) [PyPy 5.6.0 with GCC 6.2.0 20161109] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>> import sys >>>> sys.version '2.7.12 (5.6.0+dfsg-4, Nov 20 2016, 10:43:30)\n[PyPy 5.6.0 with GCC ... With this commit on MicroPython we now have: MicroPython v1.18-371-g9d08eb024 on 2022-04-28; linux [GCC 11.2.0] v... Use Ctrl-D to exit, Ctrl-E for paste mode >>> import sys >>> sys.version '3.4.0; MicroPython v1.18-371-g9d08eb024 on 2022-04-28' Note that the start of the banner is the same as the end of sys.version. This helps to keep code size under control because the string can be reused by the compiler. Signed-off-by: Damien George <damien@micropython.org>
2022-03-10py/modsys: Add optional mutable attributes sys.ps1/ps2 and use them.Damien George
This allows customising the REPL prompt strings. Signed-off-by: Damien George <damien@micropython.org>
2022-03-10py/modsys: Add optional sys.tracebacklimit attribute.Damien George
With behaviour as per CPython. Signed-off-by: Damien George <damien@micropython.org>
2022-03-10py/modsys: Add optional attribute delegation.Damien George
To be enabled when needed by specific sys attributes. Signed-off-by: Damien George <damien@micropython.org>
2021-11-19py/modsys: Replace non-ASCII quote char with ASCII char.Damien George
The source code should stay 7-bit ASCII clean. Signed-off-by: Damien George <damien@micropython.org>
2021-07-15py/modsys: Optimise sys.exit for code size by using exception helpers.Damien George
Signed-off-by: Damien George <damien@micropython.org>
2020-05-28py/modsys: Use consistent naming pattern for module-level const objects.David Lechner
This renames a few identifiers to follow the usual naming convention of mp_<module>_<name>. This makes them easier to find, e.g. when grep'ing.
2020-02-28all: Reformat C and Python source code with tools/codeformat.py.Damien George
This is run with uncrustify 0.70.1, and black 19.10b0.
2019-11-04py/modsys: Report .mpy version in sys.implementation.Damien George
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')`.
2019-08-30py: Integrate sys.settrace feature into the VM and runtime.Milan Rossa
This commit adds support for sys.settrace, allowing to install Python handlers to trace execution of Python code. The interface follows CPython as closely as possible. The feature is disabled by default and can be enabled via MICROPY_PY_SYS_SETTRACE.
2019-08-15py: Implement new sys.atexit feature.Milan Rossa
This patch implements a new sys.atexit function which registers a function that is later executed when the main script ends. It is configurable via MICROPY_PY_SYS_ATEXIT, disabled by default. This is not compliant with CPython, rather it can be used to implement a CPython compatible "atexit" module if desired (similar to how sys.print_exception can be used to implement functionality of the "traceback" module).
2018-12-22py/mpconfig: Move MICROPY_VERSION macros to static ones in mpconfig.h.Damien George
It's more robust to have the version defined statically in a header file, rather than dynamically generating it via git using a git tag. In case git doesn't exist, or a different source control tool is used, it's important to still have the uPy version number available.
2018-06-20py: Add checks for stream objects in print() and sys.print_exception().Damien George
2018-04-04py/modsys: Don't compile getsizeof function if feature is disabled.Damien George
2017-10-04all: Remove inclusion of internal py header files.Damien George
Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed.
2017-08-30py: Change obsolete "///" comment formatting to normal comments.Damien George
This comment style is no longer used because the docs are written by hand, not generated.
2017-08-11py/modsys: Initial implementation of sys.getsizeof().Paul Sokolovsky
Implemented as a new MP_UNARY_OP. This patch adds support lists, dicts and instances.
2017-07-31all: Use the name MicroPython consistently in commentsAlexander Steffen
There were several different spellings of MicroPython present in comments, when there should be only one.
2017-07-31py/modsys: Use MP_ROM_INT for int values in an mp_rom_map_elem_t.Damien George
2017-06-08py/modsys: Allow to compile with obj-repr D and PY_ATTRTUPLE disabled.Damien George
2017-05-14py/modsys: update conditionals for code referencing sys.stdoutTom Collins
Working on a build with PY_IO enabled (for PY_UJSON support) but PY_SYS_STDFILES disabled (no filesystem). There are multiple references to mp_sys_stdout_obj that should only be enabled if both PY_IO and PY_SYS_STDFILES are enabled.
2017-03-06py/modsys: Use MP_SMALL_INT_MAX for sys.maxsize in case of LONGINT_IMPL_NONE.Paul Sokolovsky
INT_MAX used previosly is indeed max value for int, whereas on LP64 platforms, long is used for mp_int_t. Using MP_SMALL_INT_MAX is the correct way to do it anyway.
2016-09-22all: Remove 'name' member from mp_obj_module_t struct.Damien George
One can instead lookup __name__ in the modules dict to get the value.
2016-01-11py: Change type signature of builtin funs that take variable or kw args.Damien George
With this patch the n_args parameter is changed type from mp_uint_t to size_t.
2015-12-16py/modsys: Fix module globals table to use MP_ROM_QSTR.Damien George
2015-12-05py/modsys: Use MP_ROM_PTR() initializer for sys.modules.Paul Sokolovsky
Based on similar usage for sys.argv/sys.path.
2015-12-05py/modsys: Implement sys.modules.Paul Sokolovsky
This for example will allow people to reload modules which didn't load successfully (e.g. due to syntax error).
2015-11-29py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.Damien George
This allows the mp_obj_t type to be configured to something other than a pointer-sized primitive type. This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts.
2015-11-29py: Add MP_ROM_* macros and mp_rom_* types and use them.Damien George
2015-11-21py/modsys: Consistently use indented #if's.Paul Sokolovsky
2015-09-04py: Eliminate some cases which trigger unused parameter warnings.Damien George
2015-04-28py: Replace py-version.sh with makeversionhdr.py, written in Python.Damien George
Also rename py-version.h to mpversion.h for consistency with mpconfig.h.
2015-04-25modsys: Add basic sys.exc_info() implementation.Paul Sokolovsky
The implementation is very basic and non-compliant and provided solely for CPython compatibility. The function itself is bad Python2 heritage, its usage is discouraged.
2015-04-21py: Add sys.implementation, containing uPy name and version number.Damien George
Uses attrtuple if it's enabled, otherwise just a normal tuple.
2015-04-16py: Make mp_sys_stdout_print object, wrapping sys.stdout for mp_print*.Damien George
So now all printing should go via either mp_plat_print or mp_sys_stdout_print.
2015-04-16py: Overhaul and simplify printf/pfenv mechanism.Damien George
Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
2015-04-09py: Use a dummy type for referring to extern structsstijn
Fixes msvc linker warnings about mismatching sizes between the mp_obj_fdfile_t struct defined in file.c and the mp_uint_t declarations found in modsys.c and modbuiltins.c
2015-02-07py: Put mp_sys_path, mp_sys_argv and gc_collected in mp_state_ctx_t.Damien George
Without mp_sys_path and mp_sys_argv in the root pointer section of the state, their memory was being incorrectly collected by GC.
2015-01-12py: Can compile with -Wmissing-declarations and -Wmissing-prototypes.Damien George
2015-01-01py: Move to guarded includes, everywhere in py/ core.Damien George
Addresses issue #1022.
2014-12-08modsys: Add sys.print_exception(exc, file=sys.stdout) function.Paul Sokolovsky
The function is modeled after traceback.print_exception(), but unbloated, and put into existing module to save overhead on adding another module. Compliant traceback.print_exception() is intended to be implemented in micropython-lib in terms of sys.print_exception(). This change required refactoring mp_obj_print_exception() to take pfenv_t interface arguments. Addresses #751.
2014-11-29Use MP_DEFINE_CONST_DICT macro to define module dicts.Damien George
This is just a clean-up of the code. Generated code is exactly the same.
2014-09-15py: Move definition of mp_sys_exit to core.Damien George
sys.exit always raises SystemExit so doesn't need a special implementation for each port. If C exit() is really needed, use the standard os._exit function. Also initialise mp_sys_path and mp_sys_argv in teensy port.
2014-08-10doc: Fix up a few docs in sys module.Damien George
