088740ecc4 py: Optimise storage of iterator so it takes only 4 slots on Py stack. 2017-02-16 18:38:06 +11:00
Damien George
6e769da0da py: Make FOR_ITER opcode pop 1+4 slots from the stack when finished. 
The extra 4 slots correspond to the iterator object stored on the stack.

f4df3aaa72 py: Allow bytecode/native to put iter_buf on stack for simple for loops. 
So that the "for x in it: ..." statement can now work without using the
heap (so long as the iterator argument fits in an iter_buf structure).

ae8d867586 py: Add iter_buf to getiter type method. 
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

TODO: still need to allocate stack memory in bytecode for iter_buf.

f980c70997 tests/basic/: Make various tests skippable. 
To run the testsuite on small ports.

b737c9cbc8 tests/gen_yield_from_close: Use range() instead of reversed(). 
As a "more basic" builtin iterator, present even in smaller ports.

05a4859585 stmhal: Implement a proper thread scheduler. 
This patch changes the threading implementation from simple round-robin
with busy waits on mutexs, to proper scheduling whereby threads that are
waiting on a mutex are only scheduled when the mutex becomes available.

f6c22a0679 py/vm: Add MICROPY_PY_THREAD_GIL_VM_DIVISOR option. 
This improves efficiency of GIL release within the VM, by only doing the
release after a fixed number of jump-opcodes have executed in the current
thread.

Damien George
234f07f16c py/modthread: Use system-provided mutexs for _thread locks. 
It's more efficient using the system mutexs instead of synthetic ones with
a busy-wait loop.  The system can do proper scheduling and blocking of the
threads waiting on the mutex.

06a12ada48 tests/thread: Add stress-test for creating many threads. 2017-02-15 11:12:37 +11:00

2847d7431d tests/thread: Replace busy waiting loops with a loop that sleeps. 
Depending on the thread scheduler, a busy-wait loop can hog the CPU and
make the tests very slow.  So convert such loops to loops that have an
explicit sleep, allowing the worker threads to do their job.

453f98914e zephyr/main: Don't unconditionally dump stats on each GC. 
This was a debug output for initial porting, breaks tests.

c6fd9ba4f3 tests: Add option to not clear MICROPYPATH when running tests 
This allows using the test runner for other scenarios than just
testing uPy itself.
The principle of comparing either to CPython or else to a .exp
file is really handy but to be able to test custom modules not
built into micropython.exe one needs to be able to specify the
module search path a.k.a MICROPYPATH.

ce2703599f zephyr: Add qemu_cortex_m3 config fragment. 
Should work for QEMU networking with soon-to-merged upstream patch.

ee3615d800 docs/uos: Remove mention of uos.sep. 
MicroPython guarantees '/' to be a path separator, so extra constant taking
precious ROM space are not needed. MicroPython never had such constant, only
one vendor port had it (now unmaintained).

dd00d0134b examples/hwapi/soft_pwm: Use Signal on()/off() methods. 
Just one sample is updated with  on()/off() for now, there should be
remaining sample(s) showing .value() use (but more can be converted later,
as long as 1 or so good samples of .value() remains).

0c821f7def docs/library/machine: Make separate TOC for WiPy vs non-WiPy. 
WiPy is the only port with ADC and SD, so they shouldn't be included in
other ports' documentation.

3625afa173 extmod/vfs: Allow to stat the root directory. 
os.stat('/') now works and returns a mostly-empty tuple.  Really all that
is useful is the mode which tells that it's a directory.

2f76c3ca0a docs/library/pyb.Pin: Minor typo fix, B6 should be A0. 
On the PYBv1.0, X1 maps to A0, not B6.

f92f7dd2bc stmhal/boards: For STM32F411DISC, change I2C pin according to datasheet. 
The pin had to be changed to get the I2C sensors on board to work.

16a3534ad4 unix/moduselect: Implement ipoll() method with no-allocation policy. 
ipoll() allows to poll streams without allocating any memory: this method
returns an iterator (a poll object itself), and the iterator yields
preallocated "callee-owned tuple" with polling results for each active
stream. The only operation a caller is allowed to do with this tuple is
extracting values from it (storing the tuple as a whole somewhere is
not allowed).
