2022-09-19py/obj: Add accessors for type slots and use everywhere.Jim Mussared
This is a no-op, but sets the stage for changing the mp_obj_type_t representation. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
2022-06-28py/builtinhelp: Don't show help for an MP_MODULE_ATTR_DELEGATION_ENTRY.Damien George
Otherwise it can lead to a crash. Fixes issue #8816. Signed-off-by: Damien George <damien@micropython.org>
2021-12-18py: Only search frozen modules when '.frozen' is found in sys.path.Jim Mussared
This changes makemanifest.py & mpy-tool.py to merge string and mpy names into the same list (now mp_frozen_names). The various paths for loading a frozen module (mp_find_frozen_module) and checking existence of a frozen module (mp_frozen_stat) use a common function that searches this list. In addition, the frozen lookup will now only take place if the path starts with ".frozen", which needs to be added to sys.path. This fixes issues #1804, #2322, #3509, #6419.

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.
2020-01-09py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.Damien George
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer, so enforce this const-ness throughout the code base. If a type ever needs to be modified (eg a user type) then a simple cast can be used.
2019-10-22py: Automatically provide weak links from "foo" to "ufoo" module name.Damien George
This commit implements automatic module weak links for all built-in modules, by searching for "ufoo" in the built-in module list if "foo" cannot be found. This means that all modules named "ufoo" are always available as "foo". Also, a port can no longer add any other weak links, which makes strict the definition of a weak link. It saves some code size (about 100-200 bytes) on ports that previously had lots of weak links. Some changes from the previous behaviour: - It doesn't intern the non-u module names (eg "foo" is not interned), which saves code size, but will mean that "import foo" creates a new qstr (namely "foo") in RAM (unless the importing module is frozen). - help('modules') no longer lists non-u module names, only the u-variants; this reduces duplication in the help listing. Weak links are effectively the same as having a set of symbolic links on the filesystem that is searched last. So an "import foo" will search built-in modules first, then all paths in sys.path, then weak links last, importing "ufoo" if it exists. Thus a file called "foo.py" somewhere in sys.path will still have precedence over the weak link of "foo" to "ufoo". See issues: #1740, #4449, #5229, #5241.

2018-07-08py: Simplify some cases of accessing the map of module and type dict.Damien George
mp_obj_module_get_globals() returns a mp_obj_dict_t*, and type->locals_dict is a mp_obj_dict_t*, so access the map entry of the dict directly instead of needing to cast this mp_obj_dict_t* up to an object and then calling the mp_obj_dict_get_map() helper function.
2018-05-02py/builtinhelp: Change occurrence of mp_uint_t to size_t.Damien George
2017-11-16py/objstr: Remove "make_qstr_if_not_already" arg from mp_obj_new_str.Damien George
This patch simplifies the str creation API to favour the common case of creating a str object that is not forced to be interned. To force interning of a new str the new mp_obj_new_str_via_qstr function is added, and should only be used if warranted. Apart from simplifying the mp_obj_new_str function (and making it have the same signature as mp_obj_new_bytes), this patch also reduces code size by a bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).
2017-09-12py/builtinhelp: Change signature of help text var from pointer to array.Damien George
As a pointer (const char *) it takes up an extra word of storage which is in RAM.
2017-09-10py/builtinhelp: Simplify code slightly by extracting object type.Damien George
Reduces code size by about 10 bytes.
2017-01-22py/builtinhelp: Implement help('modules') to list available modules.Damien George
This is how CPython does it, and it's very useful to help users discover the available modules for a given port, especially built-in and frozen modules. The function does not list modules that are in the filesystem because this would require a fair bit of work to do correctly, and is very port specific (depending on the filesystem).
2017-01-22py: Add builtin help function to core, with default help msg.Damien George
This builtin is configured using MICROPY_PY_BUILTINS_HELP, and is disabled by default.
