Paul Sokolovsky	59c675a64c	py: Include mpconfig.h before all other includes. It defines types used by all other headers. Fixes #691.	2014-06-21 22:43:22 +03:00
mux	5c8db48541	Fix asser_func warning/error * Add while(1) to assert_func to avoid func returns warning * Define a weak attr in mpconfig.h	2014-06-21 17:24:55 +02:00
Paul Sokolovsky	4c4b9d15ab	mkrules.mk: Pass $(COPT) to link stage. In generalize case, optimization options should be passed to all stages of the build process.	2014-06-20 23:49:30 +03:00
Paul Sokolovsky	0fc7efb663	makefile: Pass STRIPFLAGS_EXTRA to strip. Expected to be set on command line, with the idea being that for different targets, there're different smartass ABIs which strive to put unneeded sections into executables, etc., so let people have flexible way to strip that. The option name is similar to previously introduced CLFAGS_EXTRA & LDFLAGS_EXTRA.	2014-06-20 20:25:35 +03:00
Paul Sokolovsky	3b6f7b95eb	py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT. One thing is wanting to do 1 / 2 and get something else but 0, and quite another - doing rocket science ;-).	2014-06-20 18:00:23 +03:00

Dave Hylands	4f1b7fec9f	Updated teensy to build. Refactored some stmhal files which are shared with teensy.	2014-06-15 22:48:05 -07:00
Paul Sokolovsky	0294661da5	parsenum: Signedness issues. char can be signedness, and using signedness types is dangerous - it can lead to negative offsets when doing table lookups. We apparently should just ban char usage.	2014-06-14 18:02:21 +03:00
Paul Sokolovsky	e3cfc0d33d	objstr: Refactor to work with char pointers instead of indexes. In preparation for unicode support.	2014-06-14 06:30:30 +03:00
Paul Sokolovsky	7ddbd1bee7	unicode: Add trivial implementation of unichar_charlen().	2014-06-14 06:30:30 +03:00
Paul Sokolovsky	b0bb458810	unicode: String API is const byte*. We still have that char vs byte dichotomy, but majority of string operations now use byte.	2014-06-14 06:22:11 +03:00
Paul Sokolovsky	2ec38a17d4	objstr: Be 8-bit clean even for repr(). This will allow roughly the same behavior as Python3 for non-ASCII strings, for example, print("<phrase in non-Latin script>".split()) will print list of words, not weird hex dump (like Python2 behaves). (Of course, that it will print list of words, if there're "words" in that phrase at all, separated by ASCII-compatible whitespace; that surely won't apply to every human language in existence).	2014-06-14 01:21:13 +03:00
Damien George	c037694957	py, gc: Revert ret_ptr to void, casting to byte for memset.	2014-06-13 22:33:31 +01:00

Paul Sokolovsky	e22cddbe2a	stream: Use mp_obj_is_true() for EOF testing. Getting a length of string may be expensive, depending on the underlying implementation.	2014-06-13 23:53:10 +03:00
stijn	f33385f56d	gc: Use byte* pointers instead of void* for pointer arithmetic void* is of unknown size	2014-06-13 20:42:06 +02:00
Damien George	8340c48389	py: Revert change of include, "" back to <> for mpconfigport.h.	2014-06-12 19:50:17 +01:00
Paul Sokolovsky	fbdf2f1d63	py: Rename builtin "io" to "_io". Functionality we provide in builtin io module is fairly minimal. Some code, including CPython stdlib, depends on more functionality. So, there's a choice to either implement it in C, or move it _io, and let implement other functionality in Python. 2nd choice is pursued. This setup matches CPython too (_io is builtin, io is Python-level).	2014-06-12 01:22:25 +03:00

Chris Angelico	1f44e118f0	Remove unnecessary bounds check from mp_seq_get_fast_slice_indexes. At this point, start will be >= 0, so checking if stop < 0 is redundant with checking if start > stop a few lines later.	2014-06-10 03:59:55 +10:00
Paul Sokolovsky	195de3247b	objtype: Fix passing of class param to inherited classmethods. This is getting more and more tangled, but that's old news.	2014-06-08 22:28:44 +03:00
Paul Sokolovsky	639863d36e	objtype: Optimize stack usage mp_obj_class_lookup(). As before, instead of pushing constant values on stack again and again, just pass around pointer to a structure.	2014-06-08 20:50:12 +03:00

Paul Sokolovsky	7e4a2b0edc	py: Add generic mp_not_implemented() func to use instead of assert(). Benefits: won't crash baremetal targets, will provide Python source location when not implemented feature used (it will no longer provide C source location, but just grep for error message).	2014-06-07 23:26:27 +03:00
Damien George	aabd83ea20	py: Merge mp_execute_bytecode into fun_bc_call. This reduces stack usage by 16 words (64 bytes) for stmhal/ port. See issue #640.	2014-06-07 14:16:08 +01:00
Damien George	82ed3d62f6	py, mk: Revert change where build variables set with ?=. ?= operator does not do delayed expansion (unlike =).	2014-06-07 13:14:45 +01:00

Marcus von Appen	8ffc02495f	- Let the build environment decide about the toolchain to be used, in case there are special tweaks and paths to be considered. Just provide some defaults, in case the values are undefined. - py-version.sh does not need any bash specific features. - Use libdl only on Linux for now.

Damien George	d4c2bddd0c	py: Raise TypeError when trying to format non-int with %x,%o,%X. This behaviour follows Python 3.5 standard (in 3.4 it's a DeprecationWarning which we'd rather make a TypeError).	2014-06-05 19:44:54 +01:00
Paul Sokolovsky	f675ff3957	Merge pull request #665 from Rosuav/naming3.3 Change comments (mainly URLs) to no longer specifically say Python 3.3	2014-06-05 21:17:46 +03:00
Damien George	11de8399fe	py: Small changes to objstr.c, including a bug fix. Some small fixed: - Combine 'x' and 'X' cases in str format code. - Remove trailing spaces from some lines. - Make exception messages consistently begin with lower case (then needed to change those in objarray and objtuple so the same constant string data could be used). - Fix bug with exception message having %c instead of %%c.	2014-06-05 18:57:38 +01:00
Chris Angelico	daf973ae00	Change comments (mainly URLs) to no longer specifically say Python 3.3	2014-06-06 03:51:03 +10:00
Paul Sokolovsky	75ce9256b2	objstr: Implement "%(key)s" % {} formatting for strings and dicts. Also, make sure that args to "*" format specifiers are bounds-checked properly and don't lead for segfaults in case of mismatch.	2014-06-05 20:06:15 +03:00

Damien George	65ec33200a	py: Fix configuration of math module.	2014-06-03 12:33:38 +00:00
Damien George	bcb6ca4d5e	py: Implement full behaviour of dict.update(), and dict(). Add keyword args to dict.update(), and ability to take a dictionary as argument. dict() class constructor can now use dict.update() directly. This patch loses fast path for dict(other_dict), but is that really needed? Any anyway, this idiom will now re-hash the dictionary, so is arguably more memory efficient. Addresses issue #647.	2014-06-03 12:53:44 +01:00
Paul Sokolovsky	411732e93b	vm: If there's no lineno info, set lineno in traceback to 0, not 1. To clearly signify that lineno is not known.	2014-06-03 12:32:59 +03:00
Paul Sokolovsky	b8f117dd32	py: For optimization level -O3 and higher, remove lineno info from bytecode.	2014-06-03 12:32:59 +03:00
Paul Sokolovsky	d3439d0c60	py: Instead of having "debug on" var, have "optimization level" var. This allows to have multiple "optimization" levels (CPython has two (-OO removes docstrings), we can have more).	2014-06-03 12:32:59 +03:00

Paul Sokolovsky	b325d25e46	lexer: Add another comment for somewhat obscure way __debug__ is handled.	2014-06-02 16:35:57 +03:00
Paul Sokolovsky	62798831be	modstruct: Add one more extension to typecodes - 'S', a pointer to C string. Also, add comment with description of extension to CPython's typecodes.	2014-06-02 16:35:56 +03:00
Damien George	fcc9cf63f1	py, str: Replace enum with actual function pointer. This way, it's slightly more efficient, uses less ROM (60 bytes less for stmhal), and doesn't require to raise exception if bad operation given.	2014-06-01 18:22:09 +01:00
Damien George	c49ddb9315	py: Fix configurability of builtin slice.	2014-06-01 13:49:35 +01:00

Damien George	fb510b3bf9	Rename bultins config variables to MICROPY_PY_BUILTINS_*. This renames: MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT See issue #35 for discussion.	2014-06-01 13:32:54 +01:00
Damien George	c60a261ef0	py, vm: Replace save_ip, save_sp with code_state->{ip, sp}. This may seem a bit of a risky change, in that it may introduce crazy bugs with respect to volatile variables in the VM loop. But, I think it should be fine: code_state points to some external memory, so the compiler should always read/write to that memory when accessing the ip/sp variables (ie not put them in registers). Anyway, it passes all tests and improves on all efficiency fronts: about 2-4% faster (64-bit unix), 16 bytes less stack space per call (64-bit unix) and slightly less executable size (unix and stmhal). The reason it's more efficient is save_ip and save_sp were volatile variables, so were anyway stored on the stack (in memory, not regs). Thus converting them to code_state->{ip, sp} doesn't cost an extra memory dereference (except maybe to get code_state, but that can be put in a register and then made more efficient for other uses of it).	2014-06-01 12:32:28 +01:00
Damien George	1b87d1098a	Merge branch 'vm-alloca' of github.com:pfalcon/micropython into pfalcon-vm-alloca Conflicts: py/vm.c Fixed stack underflow check. Use UINT_FMT/INT_FMT where necessary. Specify maximum VM-stack byte size by multiple of machine word size, so that on 64 bit machines it has same functionality as 32 bit.	2014-06-01 12:06:17 +01:00
Damien George	5b5562c1d1	py: Fix stack underflow with optimised for loop.	2014-05-31 17:59:11 +01:00
Paul Sokolovsky	b4ebad3310	vm: Factor out structure with code execution state and pass it around. This improves stack usage in callers to mp_execute_bytecode2, and is step forward towards unifying execution interface for function and generators (which is important because generators don't even support full forms of arguments passing (keywords, etc.)).	2014-05-31 18:22:01 +03:00
Paul Sokolovsky	b16523aa95	vm: Don't unconditionally allocate state on stack, do that only if needed. This makes sure that only as much stack allocated as actually used, reducing stack usage for each Python function call.	2014-05-31 18:19:33 +03:00

Damien George	d8675541a9	py, vm: Where possible, make variables local to each opcode. This helps the compiler do its optimisation, makes it clear which variables are local per opcode and which global, and makes it consistent when extra variables are needed in an opcode (in addition to old obj1, obj2 pair, for example). Could also make unum local, but that's for another time.	2014-05-25 22:58:04 +01:00
Damien George	f600a6a085	py: Slightly improve efficiency of mp_obj_new_str; rename str_new. Reorder interning logic in mp_obj_new_str, to be more efficient. str_new is globally accessible, so should be prefixed with mp_obj_.	2014-05-25 22:34:34 +01:00
Damien George	2617eebf2f	Change const byte* to const char* where sensible. This removes need for some casts (at least, more than it adds need for new casts!).	2014-05-25 22:27:57 +01:00
Damien George	f88fc7bd23	Merge branch 'pfalcon-keep-strings-uninterned'	2014-05-25 22:13:47 +01:00
Damien George	5042bce8fb	py: Don't automatically intern strings in parser. This completes non-automatic interning of strings in the parser, so that doc strings don't take up RAM. It complicates the parser and compiler, and bloats stmhal by about 300 bytes. It's complicated because now there are 2 kinds of parse-nodes that can be strings: interned leaves and non-interned structs.	2014-05-25 22:06:06 +01:00

Even if we have to add something eventually, look up from there might be handled in adhoc manner, as last resort (that's not compliant with Python3 MRO, but we're already non-compliant). Hence: 1) no need to spend type trying to lookup anything in object; 2) no need to allocate subobject when explicitly inheriting from object; 3) and having multiple bases inheriting from object is not a case of incompatible multiple inheritance.	2014-05-10 16:56:20 +03:00

Damien George	66e18f04d8	py: Turn down amount of RAM parser and compiler use. There are 2 locations in parser, and 1 in compiler, where memory allocation is not precise. In the parser it's the rule stack and result stack, in the compiler it's the array for the identifiers in the current scope. All other mallocs are exact (ie they don't allocate more than is needed). This patch adds tuning options (MP_ALLOC_*) to mpconfig.h for these 3 inexact allocations. The inexact allocations in the parser should actually be close to logarithmic: you need an exponentially larger script (absent pathological cases) to use up more room on the rule and result stacks. As such, the default allocation policy for these is now to start with a modest sized stack, but grow only in small increments. For the identifier arrays in the compiler, these now start out quite small (4 entries, since most functions don't have that many ids), and grow incrementally by 6 (since if you have more ids than 4, you probably have quite a few more, but it wouldn't be exponentially more).

stijn	1dc7f0427b	More relaxed parsing of preprocessed qstr header The original parsing would error out on any C declarations that are not typedefs or extern variables. This limits what can go in mpconfig.h and mpconfigport.h, as they are included in qstr.h. For instance even a function declaration would be rejected and including system headers is a complete no-go. That seems too limiting for a global config header, so makeqstrdata now ignores everything that does not match a qstr definition.	2014-05-03 10:26:31 +02:00

Damien George	daab651c5c	py, gc: Zero out newly allocated blocks in the GC. Also add some more debugging output to gc_dump_alloc_table(). Now that newly allocated heap is always zero'd, maybe we just make this a policy for the uPy API to keep it simple (ie any new implementation of memory allocation must zero all allocations). This follows the D language philosophy. Before this patch, a previously used memory block which had pointers in it may still retain those pointers if the new user of that block does not actually use the entire block. Eg, if I want 5 blocks worth of heap, I actually get 8 (round up to nearest 4). Then I never use the last 3, so they keep their old values, which may be pointers pointing to the heap, hence preventing GC. In rare (or maybe not that rare) cases, this leads to long, unintentional "linked lists" within the GC'd heap, filling it up completely. It's pretty rare, because you have to reuse exactly that memory which is part of this "linked list", and reuse it in just the right way. This should fix issue #522, and might have something to do with issue #510.	2014-04-25 23:37:55 +01:00

Damien George	66ae8c9f49	py: Tidy up variables in VM, probably fixes subtle bugs. Things get tricky when using the nlr code to catch exceptions. Need to ensure that the variables (stack layout) in the exception handler are the same as in the bit protected by the exception handler. Prior to this patch there were a few bugs. 1) The constant mp_const_MemoryError_obj was being preloaded to a specific location on the stack at the start of the function. But this location on the stack was being overwritten in the opcode loop (since it didn't think that variable would ever be referenced again), and so when an exception occurred, the variable holding the address of MemoryError was corrupt. 2) The FOR_ITER opcode detection in the exception handler used sp, which may or may not contain the right value coming out of the main opcode loop. With this patch there is a clear separation of variables used in the opcode loop and in the exception handler (should fix issue (2) above). Furthermore, nlr_raise is no longer used in the opcode loop. Instead, it jumps directly into the exception handler. This tells the C compiler more about the possible code flow, and means that it should have the same stack layout for the exception handler. This should fix issue (1) above. Indeed, the generated (ARM) assembler has been checked explicitly, and with 'goto exception_handler', the problem with &MemoryError is fixed. This may now fix problems with rge-sm, and probably many other subtle bugs yet to show themselves. Incidentally, rge-sm now passes on pyboard (with a reduced range of integration)! Main lesson: nlr is tricky. Don't use nlr_push unless you know what you are doing! Luckily, it's not used in many places. Using nlr_raise/jump is fine.	2014-04-17 16:50:23 +01:00

Damien George	df8127a17e	py: Remove unique_codes from emitglue.c. Replace with pointers. Attempt to address issue #386. unique_code_id's have been removed and replaced with a pointer to the "raw code" information. This pointer is stored in the actual byte code (aligned, so the GC can trace it), so that raw code (ie byte code, native code and inline assembler) is kept only for as long as it is needed. In memory it's now like a tree: the outer module's byte code points directly to its children's raw code. So when the outer code gets freed, if there are no remaining functions that need the raw code, then the children's code gets freed as well. This is pretty much like CPython does it, except that CPython stores indexes in the byte code rather than machine pointers. These indices index the per-function constant table in order to find the relevant code.	2014-04-13 11:04:33 +01:00

Working towards trying to support compile-time constants (see discussion in issue #227), this patch allows the compiler to look inside arbitrary uPy objects at compile time. The objects to search are given by the macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects), and the constant folding occures on forms base.attr (both base and attr must be id's).

Damien George	88d7bba961	py: Make it so that printing a small int does not allocate heap memory. With the implementation of proper string formatting, code to print a small int was delegated to mpz_as_str_inpl (after first converting the small int to an mpz using stack memory). But mpz_as_str_inpl allocates heap memory to do the conversion, so small ints needed heap memory just to be printed. This fix has a separate function to print small ints, which does not allocate heap, and allocates less stack. String formatting, printf and pfenv are now large beasts, with some semi-duplicated code.	2014-04-08 23:30:46 +01:00

Damien George	a12a0f78b0	py: Rename pfenv_print_int to pfenv_print_mp_int, and add back former. stmhal relies on pfenv_* to implement its printf. Thus, it needs a pfenv_print_int which prints a proper 32-bit integer. With latest change to pfenv, this function became one that took mp_obj_t, and extracted the integer value from that object. To fix temporarily, pfenv_print_int has been renamed to pfenv_print_mp_int (to indicate it takes a mp_obj_t for the int), and pfenv_print_int has been added (which takes a normal C int). Currently, pfenv_print_int proxies to pfenv_print_mp_int, but this means it looses the MSB. Need to find a way to fix this, but the only way I can think of will duplicate lots of code.	2014-04-08 01:29:53 +01:00

Two things: 1) set flags in copy properly; make mp_map_init() not be too smart and do something with requested alloc size. Policy of using prime numbers for alloc size is high-level policy which should be applied at corresponding high levels. Low-level functions should just do what they're asked to, because they don't have enough context to be smarter than that. For example, munging with alloc size of course breaks dict copying (as changing sizes requires rehashing).	2014-04-06 21:31:42 +03:00

Damien George	882b363564	py: Move to Python 3.4.0 compatibility. Very little has changed. In Python 3.4 they removed the opcode STORE_LOCALS, but in Micro Python we only ever used this for CPython compatibility, so it was a trivial thing to remove. It also allowed to clean up some dead code (eg the 0xdeadbeef in class construction), and now class builders use 1 less stack word. Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not yet understood. Still, all tests (apart from bytecode test) still pass. Bytecode tests needs some more attention, but they are not that important anymore.	2014-04-02 15:56:31 +01:00

For example, native code adjusts the stack pointer on entry to the function. Native code doesn't need to know n_state for any other reason. So putting the state size in the bytecode prelude is sensible. It reduced ROM usage on STM by about 30 bytes :) And makes it easier to pass information about the bytecode between functions.	2014-03-27 11:07:04 +00:00

Damien George	9b196cddab	Remove mp_obj_type_t.methods entry and use .locals_dict instead. Originally, .methods was used for methods in a ROM class, and locals_dict for methods in a user-created class. That distinction is unnecessary, and we can use locals_dict for ROM classes now that we have ROMable maps. This removes an entry in the bloated mp_obj_type_t struct, saving a word for each ROM object and each RAM object. ROM objects that have a methods table (now a locals_dict) need an extra word in total (removed the methods pointer (1 word), no longer need the sentinel (2 words), but now need an mp_obj_dict_t wrapper (4 words)). But RAM objects save a word because they never used the methods entry. Overall the ROM usage is down by a few hundred bytes, and RAM usage is down 1 word per user-defined type/class. There is less code (no need to check 2 tables), and now consistent with the way ROM modules have their tables initialised. Efficiency is very close to equivaluent.	2014-03-26 21:47:19 +00:00
