Paul Sokolovsky bbaf68f2cb modffi: Implement 'O' type handling for func arguments. 2015-02-25 23:38:22 +02:00
Damien George 5cbeacebdb py: Make math special functions configurable and disabled by default.
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

Paul Sokolovsky 99bcaa2fb6 modffi: Add toplevel func() function to create a function by pointer. 2015-02-11 07:21:03 +08:00
Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

Damien George d95b519aa1 unix, windows: Don't call mp_unix_mark_exec on windows. 2015-01-14 11:43:51 +00:00
Damien George 2127e9a844 py, unix: Trace root pointers with native emitter under unix port.
Native code has GC-heap pointers in it so it must be scanned.  But on
unix port memory for native functions is mmap'd, and so it must have
explicit code to scan it for root pointers.
2015-01-14 00:11:09 +00:00

Damien George ddd1e18801 py: Add config option MICROPY_COMP_MODULE_CONST for module consts.
Compiler optimises lookup of module.CONST when enabled (an existing
feature).  Disabled by default; enabled for unix, windows, stmhal.
Costs about 100 bytes ROM on stmhal.
2015-01-10 14:07:24 +00:00
Damien George 89deec0bab py: Add MICROPY_PY_MICROPYTHON_MEM_INFO to enable mem-info funcs.
This allows to enable mem-info functions in micropython module, even if
MICROPY_MEM_STATS is not enabled.  In this case, you get mem_info and
qstr_info but not mem_{total,current,peak}.

stijn afd6c8e1d2 Remove obsolete bss-related code/build features
GC for unix/windows builds doesn't make use of the bss section anymore,
so we do not need the (sometimes complicated) build features and code related to it
2015-01-08 15:29:44 +01:00
Damien George 7ee91cf861 py: Add option to cache map lookup results in bytecode.
This is a simple optimisation inspired by JITing technology: we cache in
the bytecode (using 1 byte) the offset of the last successful lookup in
a map. This allows us next time round to check in that location in the
hash table (mp_map_t) for the desired entry, and if it's there use that
entry straight away.  Otherwise fallback to a normal map lookup.

Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.

On a few tests it gives >90% cache hit and greatly improves speed of
code.

Disabled by default.  Enabled for unix and stmhal ports.
2015-01-07 21:07:23 +00:00
Damien George b4b10fd350 py: Put all global state together in state structures.
This patch consolidates all global variables in py/ core into one place,
in a global structure.  Root pointers are all located together to make
GC tracing easier and more efficient.
2015-01-07 20:33:00 +00:00
Paul Sokolovsky ae58795c44 unix: Enable -fno-crossjumping for fast build.
Confirmed that it improves perfomance of simple "for i in range(N): pass"
loop by 15% on Core2.

Damien George 9ddbe291c4 py: Add include guards to mpconfig,misc,qstr,obj,runtime,parsehelper. 2014-12-29 01:02:19 +00:00
Damien George e37dcaafb4 py: Allow to properly disable builtin "set" object.
This patch makes MICROPY_PY_BUILTINS_SET compile-time option fully
disable the builtin set object (when set to 0).  This includes removing
set constructor/comprehension from the grammar, the compiler and the
emitters.  Now, enabling set costs 8168 bytes on unix x64, and 3576
bytes on stmhal.
2014-12-27 17:33:30 +00:00
Paul Sokolovsky 3b74c91684 Makefiles: Support py/*.h includes per #1022. 2014-12-27 16:32:52 +02:00
Paul Sokolovsky 9c658b6afc unix, windows: Add _os.system() call.
system() is the basic function to support automation of tasks, so have it
available builtin, for example, for bootstrapping rest of micropython
environment.
2014-12-23 12:56:24 +00:00
Paul Sokolovsky 8427c5b76c unix/windows: Make sure that process exit code is portable 8-bit value.
This fixes FORCED_EXIT internal flag leaking into Windows exit code.
2014-12-19 00:01:49 +02:00
Paul Sokolovsky 9d944c7fb2 unix: Rename "time" module to "utime" to allow extensibility.
Name choosen per latest conventions and for compatibiity with stmhal port.
2014-12-17 00:13:32 +02:00
Paul Sokolovsky 0078561303 modffi: Support void (None) return value for Python callback functions. 2014-12-16 00:28:12 +02:00

Nikita Nazarenko d51107927d unix: add unlink function to os module 2014-12-10 21:49:24 +00:00
Damien George 78d702c300 py: Allow builtins to be overridden.
This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
which, when enabled, allows to override all names within the builtins
module.  A builtins override dict is created the first time the user
assigns to a name in the builtins model, and then that dict is searched
first on subsequent lookups.  Note that this implementation doesn't
allow deleting of names.

This patch also does some refactoring of builtins code, creating the
modbuiltins.c file.

Addresses issue #959.
2014-12-09 16:19:48 +00:00
Paul Sokolovsky 46c3ab2004 modsys: Add sys.print_exception(exc, file=sys.stdout) function.
The function is modeled after traceback.print_exception(), but unbloated,
and put into existing module to save overhead on adding another module.
Compliant traceback.print_exception() is intended to be implemented in
micropython-lib in terms of sys.print_exception().

This change required refactoring mp_obj_print_exception() to take pfenv_t
interface arguments.

Addresses #751.
2014-12-08 20:25:49 +00:00
Damien George be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.

Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.

Addresses issues #779 and #998.
2014-12-05 23:13:52 +00:00
Damien George a4c52c5a3d py: Optimise lexer by exposing lexer type.
mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer
functions (like checking current token kind) are now inlined.

This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460
bytes on bare-arm.  It also saves a tiny bit of RAM since mp_lexer_t
is a bit smaller.  Also will run a bit more efficiently.

Paul Sokolovsky 838eb1fa2d stream: Implement seek operation support via ioctl, wrapped in generic method.
Also, implement for unix port.
2014-11-17 00:16:14 +02:00
Paul Sokolovsky 98d8d59c33 unix: Allow -X heapsize number take 'w' specifier for word size adjustment.
The specifier should go after the number, before size suffix like 'k' or 'm'.
E.g.: "-X heapsize=100wk" will use 100K heap on 32-bit system and 200K - on
64-bit.
2014-11-05 22:47:30 +00:00
Paul Sokolovsky 346aacf27f unix: fast: Set initial module dict size big to have high pystone score.
For this, introduce MICROPY_MODULE_DICT_SIZE config setting.
2014-11-05 00:30:21 +02:00
Paul Sokolovsky 1060baa2c2 unix: Provide "fast" target to build interpreter for benchmarking.
This build is primarily intended for benchmarking, and may have random
features enabled/disabled to get high scores in synthetic benchmarks.
The intent is to show/prove that MicroPython codebase can compete with
CPython, when configured appropriately. But the main MicroPython aim
still remains to optimize for memory usage (which inevitibly leads to
performance degradation in some areas on some workloads).
2014-11-02 18:17:43 +02:00
Damien George 109c1de015 py: Make gc.enable/disable just control auto-GC; alloc is still allowed.
gc.enable/disable are now the same as CPython: they just control whether
automatic garbage collection is enabled or not.  If disabled, you can
still allocate heap memory, and initiate a manual collection.

stijn 4e54c876a7 Add -Wpointer-arith flag to prevent problems with pointer arithmetic on void* 2014-10-29 10:29:09 +01:00
Paul Sokolovsky 429e3f077e unix: Make -v dump memory info at exit.
Also, move bytecode dumps to -v -v, because they're too verbose for just -v.
2014-10-26 22:36:56 +00:00
Paul Sokolovsky e503512f83 unix: Implement -m option (execute module from stdlib).
Support for packages as argument not implemented, but otherwise error and
exit handling should be correct. This for example will allow to do:

pip-micropython install micropython-test.pystone
micropython -m test.pystone

Damien George c76af32575 unix/windows: Disable sigaction on windows port. 2014-10-26 00:42:41 +01:00
Damien George 124df6f8d0 py: Add mp_pending_exception global variable, for VM soft interrupt.
This allows to implement KeyboardInterrupt on unix, and a much safer
ctrl-C in stmhal port.  First ctrl-C is a soft one, with hope that VM
will notice it; second ctrl-C is a hard one that kills anything (for
both unix and stmhal).

One needs to check for a pending exception in the VM only for jump
opcodes.  Others can't produce an infinite loop (infinite recursion is
caught by stack check).
2014-10-25 23:37:57 +01:00
Damien George c9fc620723 py: Implement compile builtin, enabled only on unix port.
This should be pretty compliant with CPython, except perhaps for some
corner cases to do with globals/locals context.

stijn 2fe4cf7761 Implement kwargs for builtin open() and _io.FileIO
This makes open() and _io.FileIO() more CPython compliant.
The mode kwarg is fully iplemented.
The encoding kwarg is allowed but not implemented; mainly to allow
the tests to specify encoding for CPython, see #874
2014-10-21 22:10:01 +03:00
Paul Sokolovsky 1a55b6a787 unix, stmhal: Implement file.readinto() method.
Also, usocket.readinto(). Known issue is that .readinto() should be available
only for binary files, but micropython uses single method table for both
binary and text files.

Damien George b0261341d3 py: For malloc and vstr functions, use size_t exclusively for int type.
It seems most sensible to use size_t for measuring "number of bytes" in
malloc and vstr functions (since that's what size_t is for).  We don't
use mp_uint_t because malloc and vstr are not Micro Python specific.

Damien George 25fc41dd31 unix, modtermios: Make it properly configurable; fix spelling mistake. 2014-08-24 13:19:22 +01:00
Paul Sokolovsky 4f9ebade60 modtermios: Add "termios" unix module, subset of CPython's.
Also provides setraw() function from "tty" module (which in CPython is
implemented in Python). The idea here is that 95% of "termios" module usage
