Damien George 30f3bcdd29 gitattributes: Remove obsolete lines. 2017-02-17 10:27:34 +11:00
Damien George 9214e39b3c gitattributes: Add .mpy files to list of binary files. 2017-02-17 10:23:14 +11:00
Damien George 6a11048af1 py/persistentcode: Bump .mpy version due to change in bytecode. 2017-02-17 00:19:34 +11:00
Damien George c264414746 py/lexer: Don't generate string representation for period or ellipsis. 
It's not needed.

Damien George 0ec957d7c5 tests/cmdline: Update cmd_parsetree test for changes to grammar order. 2017-02-16 19:45:07 +11:00
Damien George 71019ae4f5 py/grammar: Group no-compile grammar rules together to shrink tables. 
Grammar rules have 2 variants: ones that are attached to a specific
compile function which is called to compile that grammar node, and ones
that don't have a compile function and are instead just inspected to see
what form they take.

In the compiler there is a table of all grammar rules, with each entry
having a pointer to the associated compile function.  Those rules with no
compile function have a null pointer.  There are 120 such rules, so that's
120 words of essentially wasted code space.

By grouping together the compile vs no-compile rules we can put all the
no-compile rules at the end of the list of rules, and then we don't need
to store the null pointers.  We just have a truncated table and it's
guaranteed that when indexing this table we only index the first half,
the half with populated pointers.

This patch implements such a grouping by having a specific macro for the
compile vs no-compile grammar rules (DEF_RULE vs DEF_RULE_NC).  It saves
around 460 bytes of code on 32-bit archs.

Damien George 7839b8b827 tests/micropython/heapalloc_iter: Add tests for contains and unpack. 2017-02-16 19:11:34 +11:00
Damien George e6003f466e py: De-optimise some uses of mp_getiter, so they don't use the C stack. 
In these cases the heap is anyway used to create a new object so no real
need to use the C stack for iterating.  It saves a few bytes of code size.
 2017-02-16 19:11:34 +11:00
Damien George 019048a6dc tests/micropython: Add test for iterating with the heap locked. 2017-02-16 19:11:34 +11:00
Damien George 86b3db9cd0 tests/cmdline/cmd_showbc: Update to work with recent changes. 2017-02-16 18:38:07 +11:00
Damien George 4d2bab1444 py/compile: Optimise list/dict/set comprehensions to use stack iter. 2017-02-16 18:38:07 +11:00
Damien George 861b001783 tests/cmdline: Update tests to pass with latest changes to bytecode. 2017-02-16 18:38:07 +11:00
Damien George cb6300697c py/runtime: Optimise case of identity iterator so it doesn't alloc RAM. 2017-02-16 18:38:06 +11:00
Damien George 30b42dd72d py: Remove unused "use_stack" argument from for_iter_end emit function. 2017-02-16 18:38:06 +11:00
Damien George 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.
 2017-02-16 18:38:06 +11:00
Damien George 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).
 2017-02-16 18:38:06 +11:00
Damien George 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.

Paul Sokolovsky f980c70997 tests/basic/: Make various tests skippable. 
To run the testsuite on small ports.
 2017-02-15 18:11:16 +03:00
Paul Sokolovsky b737c9cbc8 tests/gen_yield_from_close: Use range() instead of reversed(). 
As a "more basic" builtin iterator, present even in smaller ports.
 2017-02-15 17:05:27 +03:00
Paul Sokolovsky eb101a2701 examples/embedding/README: Convert to markdown, grammar and clarity fixes. 2017-02-15 13:27:24 +03:00
Damien George e5cc681cb1 stmhal: Use generic interrupt char code. 2017-02-15 16:39:30 +11:00
Damien George 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.
 2017-02-15 13:28:48 +11:00
Damien George 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.
 2017-02-15 11:28:15 +11:00
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.
 2017-02-15 11:28:02 +11:00
Damien George 06a12ada48 tests/thread: Add stress-test for creating many threads. 2017-02-15 11:12:37 +11:00
Damien George 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.

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