Before that, the output was truncated to 32 bits. Only "%x" format is
handled, because a typical use is for addresses.
This refactor actually decreased x86_64 code size by 30 bytes.
This allows the function to raise an exception when unknown keyword args
are passed in. This patch also reduces code size by (in bytes):
bare-arm: -24
minimal x86: -76
unix x64: -56
unix nanbox: -84
stm32: -40
esp8266: -68
cc3200: -48
Furthermore, this patch adds space (" ") to the set of ROM qstrs which
means it doesn't need to be put in RAM if it's ever used.
Return the result of called function. If exception happened, return
MP_OBJ_NULL. Allows to use mp_call_function_*_protected() with callbacks
returning values, etc.
The parameter order in the example for ticks_diff was incorrect. If it's
"too early" that means that scheduled time is greater than current time and
if it's "running late" then scheduled time would be less than current time.
This commit essentially reverts aa9dbb1b03
where this if-condition was added. It seems that even when that commit
was made the code was never reached by any tests, nor reachable by
analysis (see below). The same is true with the code as it currently
stands: no test triggers this if-condition, nor any uasyncio examples.
Analysing the flow of the program also shows that it's not reachable:
==START==
-> to trigger this if condition mp_execute_bytecode() must return
MP_VM_RETURN_YIELD with *sp==MP_OBJ_STOP_ITERATION
-> mp_execute_bytecode() can only return MP_VM_RETURN_YIELD from the
MP_BC_YIELD_VALUE bytecode, which can happen in 2 ways:
-> 1) from a "yield <x>" in bytecode, but <x> must always be a proper
object, never MP_OBJ_STOP_ITERATION; ==END1==
-> 2) via yield from, via mp_resume() which must return
MP_VM_RETURN_YIELD with ret_value==MP_OBJ_STOP_ITERATION, which
can happen in 3 ways:
-> 1) it delegates to mp_obj_gen_resume(); go back to ==START==
-> 2) it returns MP_VM_RETURN_YIELD directly but with a guard that
ret_val!=MP_OBJ_STOP_ITERATION; ==END2==
-> 3) it returns MP_VM_RETURN_YIELD with ret_val set from
mp_call_method_n_kw(), but mp_call_method_n_kw() must return a
proper object, never MP_OBJ_STOP_ITERATION; ==END3==
The above shows there is no way to trigger the if-condition and it can be
removed.
Prior to this fix, enabling WebREPL for the first time via webrepl_setup
did not work at all because "boot.py" did not contain any lines with
"webrepl" in them that could be uncommented.
These checks are assumed to be true in all cases where gc_realloc is
called with a valid pointer, so no need to waste code space and time
checking them in a non-debug build.
So long as the input qstr identifier is valid (below the maximum number of
qstrs) the function will always return a valid pointer. This patch
eliminates the "return 0" dead-code.
This time hopefully should work reliably, using make $(wildcard) function,
which in this case either expands to existing prj_$(BOARD).conf file, or to
an empty string for non-existing one.
This patch improves parsing of floating point numbers by converting all the
digits (integer and fractional) together into a number 1 or greater, and
then applying the correct power of 10 at the very end. In particular the
multiple "multiply by 0.1" operations to build a fraction are now combined
together and applied at the same time as the exponent, at the very end.
This helps to retain precision during parsing of floats, and also includes
a check that the number doesn't overflow during the parsing. One benefit
is that a float will have the same value no matter where the decimal point
is located, eg 1.23 == 123e-2.
Put offset first in OR expressions, and use "offset" var instead of
hardcoded numbers. Hopefully, this will make it more self-describing
and show patterns better.
Dramatically improves TCP sending throughput because without an explicit
call to tcp_output() the data is only sent to the lower layers via the
lwIP slow timer which (by default) ticks every 500ms.
Before this patch MP_BINARY_OP_IN had two meanings: coming from bytecode it
meant that the args needed to be swapped, but coming from within the
runtime meant that the args were already in the correct order. This lead
to some confusion in the code and comments stating how args were reversed.
It also lead to 2 bugs: 1) containment for a subclass of a native type
didn't work; 2) the expression "{True} in True" would illegally succeed and
return True. In both of these cases it was because the args to
MP_BINARY_OP_IN ended up being reversed twice.
To fix these things this patch introduces MP_BINARY_OP_CONTAINS which
corresponds exactly to the __contains__ special method, and this is the
operator that built-in types should implement. MP_BINARY_OP_IN is now only
emitted by the compiler and is converted to MP_BINARY_OP_CONTAINS by
swapping the arguments.
In mp_binary_op, there is no need to explicitly check for type->getiter
being non-null and raising an exception because this is handled exactly by
mp_getiter(). So just call the latter unconditionally.
