* all: Make static dicts use mp_rom_map_elem_t type and MP_ROM_xxx macros.Damien George2017-08-21
|
* all: Make use of $(TOP) variable in Makefiles, instead of "..".Damien George2017-08-11
| | | | | $(TOP) is defined in py/mkenv.mk and should be used to refer to the top level of this repository.
* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* all: Remove trailing spaces, per coding conventions.Damien George2017-07-19
|
* all: Move BYTES_PER_WORD definition from ports to py/mpconfig.hDamien George2017-04-01
| | | | | It can still be overwritten by a port in mpconfigport.h but for almost all cases one can use the provided default.
* bare-arm/Makefile: Change C standard from gnu99 to c99.Damien George2017-03-23
|
* all/Makefile: Remove -ansi from GCC flags, its ignored anyway.Krzysztof Blazewicz2017-03-23
| | | | | | The -ansi flag is used for C dialect selection and it is equivalent to -std=c90. Because it goes right before -std=gnu99 it is ignored as for conflicting flags GCC always uses the last one.
* bare-arm/main: Move lexer constructor to within NLR handler block.Damien George2017-03-14
| | | | And raise an exception when mp_lexer_new_from_file is called.
* py/nlr.h: Mark nlr_jump_fail as NORETURN.Damien George2017-03-06
|
* py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.Damien George2016-10-21
| | | | | | | In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros.
* py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled.Delio Brignoli2016-09-05
| | | | | | | | This new config option allows to control whether MicroPython uses its own internal printf or not (if not, an external one should be linked in). Accompanying this new option is the inclusion of lib/utils/printf.c in the core list of source files, so that ports no longer need to include it themselves.
* ports: Remove typedef of machine_ptr_t, it's no longer needed.Damien George2016-08-15
| | | | | | This type was used only for the typedef of mp_obj_t, which is now defined by the object representation. So we can now remove this unused typedef, to simplify the mpconfigport.h file.
* lib/utils/pyexec: Condition-out GC calls from pyexec.Colin Hogben2016-04-19
| | | | | | | | | A port which uses lib/utils/pyexec.c but which does not enable garbage collection should not need to implement the gc_collect function. This patch also moves the gc_collect call to after printing the qstr info. Since qstrs cannot be collected it should not make any difference to the printed statistics.
* ports: Disable async/await on bare-arm, minimal, pic16bit, cc3200.Damien George2016-04-13
| | | | It costs 1188 bytes of code on Thumb 2 archs.
* py: Change type signature of builtin funs that take variable or kw args.Damien George2016-01-11
| | | | | With this patch the n_args parameter is changed type from mp_uint_t to size_t.
* py: Change struct and macro for builtin fun so they can be type checked.Damien George2016-01-03
|
* all: Add py/mphal.h and use it in all ports.Damien George2015-10-31
| | | | | | py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations.
* Makefiles: Remove duplicate object files when linking.Paul Sokolovsky2015-10-24
| | | | | | | | | | | Scenario: module1 depends on some common file from lib/, so specifies it in its SRC_MOD, and the same situation with module2, then common file from lib/ eventually ends up listed twice in $(OBJ), which leads to link errors. Make is equipped to deal with such situation easily, quoting the manual: "The value of $^ omits duplicate prerequisites, while $+ retains them and preserves their order." So, just use $^ consistently in all link targets.
* all: Make netutils.h available to all ports by default.Paul Sokolovsky2015-10-19
| | | | | Generally, ports should inherit INC from py.mk, append to it, not overwrite it. TODO: Likely should do the same for other vars too.
* py: Remove dependency on printf/fwrite in mp_plat_print.Damien George2015-10-15
| | | | See issue #1500.
* py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.Damien George2015-10-02
| | | | | | | | With this patch parse nodes are allocated sequentially in chunks. This reduces fragmentation of the heap and prevents waste at the end of individually allocated parse nodes. Saves roughly 20% of RAM during parse stage.
* bare-arm: Disable enumerate and reversed builtins to make port more bare.Damien George2015-08-02
|
* py: Make qstr hash size configurable, defaults to 2 bytes.Damien George2015-07-20
| | | | | | | This patch makes configurable, via MICROPY_QSTR_BYTES_IN_HASH, the number of bytes used for a qstr hash. It was originally fixed at 2 bytes, and now defaults to 2 bytes. Setting it to 1 byte will save ROM and RAM at a small expense of hash collisions.
* bare-arm, minimal, qemu-arm: Make do_str() take parse-input-kind as arg.Damien George2015-06-22
| | | | | | | The do_str() function is provided essentially as documentation to show how to compile and execute a string. This patch makes do_str take an extra arg to specify how the string should be interpreted: either as a single line (ie from a REPL) or as multiple lines (ie from a file).
* py: Use a wrapper to explicitly check self argument of builtin methods.Damien George2015-06-20
| | | | | | | | | | | | | | | Previous to this patch a call such as list.append(1, 2) would lead to a seg fault. This is because list.append is a builtin method and the first argument to such methods is always assumed to have the correct type. Now, when a builtin method is extracted like this it is wrapped in a checker object which checks the the type of the first argument before calling the builtin function. This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and is enabled by default. See issue #1216.
* py: Add attrtuple object, for space-efficient tuples with attr access.Damien George2015-04-21
| | | | | If you need the functionality of a namedtuple but will only make 1 or a few instances, then use an attrtuple instead.
* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
* py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options.Damien George2015-03-14
| | | | | | These allow to fine-tune the compiler to select whether it optimises tuple assignments of the form a, b = c, d and a, b, c = d, e, f. Sensible defaults are provided.
* py: Protect mp_parse and mp_compile with nlr push/pop block.Damien George2015-02-07
| | | | | | | | | | 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.
* py: Add config option MICROPY_COMP_MODULE_CONST for module consts.Damien George2015-01-10
| | | | | | 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.
* py: Disable stack checking by default; enable on most ports.Damien George2015-01-09
|
* py: Put all global state together in state structures.Damien George2015-01-07
| | | | | | 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.
* bare-arm: Prefix includes with py/; remove need for -I../py.Damien George2015-01-01
|
* Makefiles: Support py/*.h includes per #1022.Paul Sokolovsky2014-12-27
|
* modsys: Add sys.print_exception(exc, file=sys.stdout) function.Paul Sokolovsky2014-12-08
| | | | | | | | | | | | 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.
* py: Optimise lexer by exposing lexer type.Damien George2014-12-05
| | | | | | | | | 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.
* ports: Define mp_off_t.Paul Sokolovsky2014-11-17
|
* py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled.Damien George2014-11-06
| | | | | | | | Going from MICROPY_ERROR_REPORTING_NORMAL to MICROPY_ERROR_REPORTING_TERSE now saves 2020 bytes ROM for ARM Thumb2, and 2200 bytes ROM for 32-bit x86. This is about a 2.5% code size reduction for bare-arm.
* bare-arm: Add dummy __assert_func and __fatal_errorSven Wegener2014-11-05
| | | | | | Required to build bare-arm with debugging. Signed-off-by: Sven Wegener <sven.wegener@stealer.net>
* py: Add builtin memoryview object (mostly using array code).Damien George2014-10-23
|
* Implement kwargs for builtin open() and _io.FileIOstijn2014-10-21
| | | | | | | 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
* py: Make compiler return a proper exception on SyntaxError.Damien George2014-10-05
|
* py: Free non-interned strings in the parser when not needed.Damien George2014-09-23
| | | | | | | | | | | mp_parse_node_free now frees the memory associated with non-interned strings. And the parser calls mp_parse_node_free when discarding a non-used node (such as a doc string). Also, the compiler now frees the parse tree explicitly just before it exits (as opposed to relying on the caller to do this). Addresses issue #708 as best we can.
* py: Print imported module's location (__file__) if available.Damien George2014-09-08
|
* py: Fix bug where GC collected native/viper/asm function data.Damien George2014-08-24
| | | | | | | | Because (for Thumb) a function pointer has the LSB set, pointers to dynamic functions in RAM (eg native, viper or asm functions) were not being traced by the GC. This patch is a comprehensive fix for this. Addresses issue #820.
* py: #if guard qstrs that are optional.Damien George2014-08-12
| | | | Also disable gc module on bare-arm port.
* Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.Damien George2014-08-04
| | | | | | | qstr_init is always called exactly before mp_init, so makes sense to just have mp_init call it. Similarly with mp_init_emergency_exception_buf. Doing this makes the ports simpler and less error prone (ie they can no longer forget to call these).
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* bare-arm: Hint of setting MICROPY_ERROR_REPORTING to REPORTING_TERSE.Paul Sokolovsky2014-06-27
| | | | | Commented out so far, as enabled leads to dozen more bytes used actually (due to string pooling effects).
* bare-arm: Disable array module and even bytearray type.Paul Sokolovsky2014-06-27
| | | | To squeeze few more hundreds of bytes.
