Damien George f935bce3c5 py/{emitbc,asmbase}: Only clear emit labels to -1 when in debug mode.
Clearing the labels to -1 is purely a debugging measure.  For release
builds there is no need to do it as the label offset table should always
have the correct value assigned.

Paul Sokolovsky 9ef4be8b41 py/gc: Add CLEAR_ON_SWEEP option to debug mis-traced objects.
Accessing them will crash immediately instead still working for some time,
until overwritten by some other data, leading to much less deterministic
crashes.

Paul Sokolovsky 9ebc037eee py/malloc: Allow to use debug logging if !MICROPY_MALLOC_USES_ALLOCATED_SIZE.
This is mostly a workaround for forceful rebuilding of mpy-cross on every
codebase change. If this file has debug logging enabled (by patching),
mpy-cross build failed.

Paul Sokolovsky 88a8043a27 py/malloc: MICROPY_MEM_STATS requires MICROPY_MALLOC_USES_ALLOCATED_SIZE.

Paul Sokolovsky f5e097021c py/mpprint: Fix "%x" vs "%X" regression introduced in previous commit. 2017-12-07 10:31:14 +02:00
Paul Sokolovsky 5a10e63543 py/mpprint: Support "%lx" format on 64-bit systems.
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.

Paul Sokolovsky 5f8ad284f8 py/mpprint: Make "%p" format work properly on 64-bit systems.
Before, the output was truncated to 32 bits.

Paul Sokolovsky ada1dc1c03 zephyr/CMakeLists.txt: Properly separate CFLAGS parts gotten from CMake.
Lack of spaces between them led to weird option artifacts like -Ifoo-Dbar.

Damien George 58f00d7c0e py/modbuiltins: Use standard arg-parsing helper func for builtin print.
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.

Paul Carver 7d25a19220 docs/library/utime: Fix incorrect example with ticks_diff args order.
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.

Damien George 64f11470be py/objgenerator: Remove unreachable code for STOP_ITERATION case.
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.

Damien George 4e056d82cc esp8266/modules/webrepl_setup: Fix first-time enable of WebREPL.
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.

Damien George 74fad3536b py/gc: In gc_realloc, convert pointer sanity checks to assertions.
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.

Damien George 8e323b8fa8 py/qstr: Rewrite find_qstr to make manifest that it returns a valid ptr.
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.

Paul Sokolovsky b369c1bb96 zephyr/Makefile: Make prj_$(BOARD).conf optional, again.
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.

Damien George 84895f1a21 py/parsenum: Improve parsing of floating point numbers.
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.

these flags aren't valid in the input eventmask. Instead, they can be
returned in unsolicited manner in the output eventmask at any time.

Paul Sokolovsky 50cffcfe2c docs/uctypes: Tweak descriptor reference to hopefully be easier to follow.
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.

Damien George 48f6990fbc extmod/modlwip: Commit TCP out data to lower layers if buffer gets full.
Dramatically improves TCP sending throughput because without an explicit

Damien George 505671b698 tests/basics: Add test for containment of a subclass of a native type. 2017-11-24 14:48:41 +11:00
Damien George 5e34a113ea py/runtime: Add MP_BINARY_OP_CONTAINS as reverse of MP_BINARY_OP_IN.
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.

Damien George 5b2f62aff3 py/opmethods: Include the correct header for binary op enums.
By directly including runtime0.h the mpconfig.h settings are not included
and so the enums in runtime0.h can be incorrect.
