Damien George 69661f3343 all: Reformat C and Python source code with tools/codeformat.py.
This is run with uncrustify 0.70.1, and black 19.10b0.

Damien George abe2caf6df py/scheduler: Move clearing of kbd traceback to mp_keyboard_interrupt.
This is a more logical place to clear the KeyboardInterrupt traceback,
right before it is set as a pending exception.  The clearing is also
optimised from a function call to a simple store of NULL.

Damien George 9efb36bfa6 py/scheduler: Move mp_keyboard_interrupt from lib/utils to py core.
This function is tightly coupled to the state and behaviour of the
scheduler, and is a core part of the runtime: to schedule a pending
exception.  So move it there.

Damien George 5a91cd9ff3 lib/utils/pyexec: Handle pending exceptions after disabling kbd intrs.
Pending exceptions would otherwise be handled later on where there may not
be an NLR handler in place.

A similar fix is also made to the unix port's REPL handler.

Fixes issues #4921 and #5488.

odewdney b51a2c266a lib/utils: Change default value of pyexec_mode_kind to 0 to put in bss.
By simply reordering the enums for pyexec_mode_kind_t it eliminates a data
variable which costs ROM to initialise it.  And the minimal build now has
nothing in the data section.

It seems the compiler is smart enough so that the generated code for
if-logic which tests these enum values is unchanged.

Yonatan Goldschmidt 61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.

Damien George 09376f0e47 py: Introduce MP_ROM_NONE macro for ROM to refer to None object.
This helps to prevent mistakes, and allows easily changing the ROM value of
None if needed.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.
mp_compile no longer takes an emit_opt argument, rather this setting is now
provided by the global default_emit_opt variable.

Now, when -X emit=native is passed as a command-line option, the emitter
will be set for all compiled modules (included imports), not just the
top-level script.

In the future there could be a way to also set this variable from a script.

Fixes issue #4267.

Damien George b7da67cdaa lib/utils/sys_stdio_mphal: Add support to poll sys.stdin and sys.stdout.
A port must provide the following function for this to work:

    uintptr_t mp_hal_stdio_poll(uintptr_t poll_flags);

Damien George 2459162599 lib/utils/interrupt_char: Invalidate interrupt char at start up.
Otherwise mp_interrupt_char will have a value of zero on start up (because
it's in the BSS) and a KeyboardInterrupt may be raised during start up.
For example this can occur if there is a UART attached to the REPL which
sends spurious null bytes when the device turns on.

Andrew Leech 859596ce25 lib/utils: Make pyexec_file_if_exists run frozen scripts if they exist.
So that boot.py and/or main.py can be frozen (either as STR or MPY) in the
same way that other scripts are frozen.  Frozen scripts have preference to
scripts in the VFS.
2019-05-01 11:27:51 +10:00
Damien George 06a532c227 lib/utils/pyexec: Add pyexec_file_if_exists() helper function.
It will only execute the script if it can be stat'd and is a file.

Mike Causer 812969d615 all: Change PYB message prefix to MPY.
Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between
ports, which is a general goal.  And this change won't break pyboard.py
because that tool only looks for "soft reboot".

Damien George 90e1303b2d lib/utils/gchelper_m3: Add license header and clean up code.
This file generates the same code with the cortex-m3 and cortex-m4
assembler directive, so use cortex-m3 to support more CPUs.

Damien George f5d46a88aa lib/utils/pyexec: Forcefully unlock the heap if locked and REPL active.
Otherwise there is really nothing that can be done, it can't be unlocked by
the user because there is no way to allocate memory to execute the unlock.

See issue #4205 and #4209.

Damien George da2d2b6d88 py/mpconfig.h: Introduce MICROPY_DEBUG_PRINTER for debugging output.
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct.  This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.

Ports are updated to use the new macro name.

Glenn Ruben Bakke 8a4a05c1ee lib/utils: Expose pyb_set_repl_info function public
The patch enables the possibility to disable or initialize the repl
info from outside of the module. Can also be used to initialize the
repl_display_debugging_info in pyexec.c if not startup file is clearing
.bss segment.

stijn 8ad30fa433 lib/utils/printf: Make DEBUG_printf implementation more accessible.
The definition of DEBUG_printf doesn't depend on
MICROPY_USE_INTERNAL_PRINTF so move it out of that preprocessor
block and compile it conditionally just depending on the
MICROPY_DEBUG_PRINTERS macro. This allows a port to use DEBUG_printf
while providing it's own printf definition.

Damien George 925c5b1da2 lib/utils/pyexec.h: Include py/obj.h because its decls are needed. 2018-01-31 18:21:07 +11:00
Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
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.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Alexander Steffen 299bc62586 all: Unify header guard usage.
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.

This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.

The rules are as follows.

Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _

In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.

py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h

Damien George 4f9858e86d stmhal: Move pybstdio.c to lib/utils/sys_stdio_mphal.c for common use.
It provides sys.stdin, sys.stdout, sys.stderr for bare-metal targets based

Damien George ab954ed513 lib/utils/interrupt_char: Remove support for KBD_EXCEPTION disabled.
If a port is using interrupt_char.c then it must enable
MICROPY_KBD_EXCEPTION.  This is the case for all official ports.

Damien George 895807137e lib/utils: Remove old pyhelp helper, replaced with py/builtinhelp.c.
Ports should no longer use pyhelp_print_obj but instead should define
MICROPY_PY_BUILTINS_HELP to 1 and then specify their help text using
MICROPY_PY_BUILTINS_HELP_TEXT.

Damien George d89cafd5c3 lib/utils/interrupt_char: Use core-provided mp_kbd_exception if enabled.
Ultimately all ports that use lib/utils/interrupt_char would enable
MICROPY_KBD_EXCEPTION, so this is an interim solution.

Paul Sokolovsky 3cdccb9b14 zephyr: Fix mp_hal_set_interrupt_char() declaration to be compatible.
With other ports. Other ports declare it in mphalport.h, it can be
inline or macro.

Paul Sokolovsky 6832cbd69d lib/utils/pyexec: Fix compilation warning of type vs format mismatch.
This happens with some compilers on some architectures, which don't define
size_t as unsigned int. MicroPython's printf() dooesn't support obscure
format specifiers for size_t, so the obvious choice is to explicitly cast
to unsigned, to match %u used in printf().

Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Damien George ad3724e0bc lib/utils/pyexec: Allow behaviour of SystemExit to be configurable.
Setting the pyexec_system_exit variable to PYEXEC_FORCED_EXT allows
SystemExit exceptions to terminate the pyexec functions.

Damien George 824f5c5a32 py/vstr: Combine vstr_new_size with vstr_new since they are rarely used.
Now there is just one function to allocate a new vstr, namely vstr_new
(in addition to vstr_init etc).  The caller of this function should know
what initial size to allocate for the buffer, or at least have some policy
or config option, instead of leaving it to a default (as it was before).

Paul Sokolovsky 4021b1e1b8 lib/utils/pyexec: Don't treat SystemExit as "forced exit".
"Forced exit" is treated as soft-reboot (Ctrl+D). But expected effect of
calling sys.exit() is termination of the current script, not any further
and more serious actions like mentioned soft reboot.
