* Revert "py/objstr: .format(): Avoid call to vstr_null_terminated_str()."Paul Sokolovsky2016-05-09
| | | | | | This reverts commit 6de8dbb4880e58c68a08205cb2b9c15940143439. The change was incorrect (correct change would require comparing with end pointer in each if statement in the block).
* py/vstr: vstr_null_terminated_str(): Extend string by at most one byte.Paul Sokolovsky2016-05-09
| | | | | | | vstr_null_terminated_str is almost certainly a vstr finalization operation, so it should add the requested NUL byte, and not try to pre-allocate more. The previous implementation could actually allocate double of the buffer size.
* py/objstr: .format(): Avoid call to vstr_null_terminated_str().Paul Sokolovsky2016-05-09
| | | | | By comparing with string end pointer instead of checking for NUL byte. Should alleviate reallocations and fragmentation a tiny bit.
* py/mpz: Fix mpn_div so that it doesn't modify memory of denominator.Damien George2016-05-09
| | | | | | | | | | | | | Previous to this patch bignum division and modulo would temporarily modify the RHS argument to the operation (eg x/y would modify y), but on return the RHS would be restored to its original value. This is not allowed because arguments to binary operations are const, and in particular might live in ROM. The modification was to normalise the arg (and then unnormalise before returning), and this patch makes it so the normalisation is done on the fly and the arg is now accessed as read-only. This change doesn't increase the order complexity of the operation, and actually reduces code size.
* py/mpz: Do Python style division/modulo within bignum divmod routine.Damien George2016-05-08
| | | | | This patch consolidates the Python logic for division/modulo to one place within the bignum code.
* py/mpz: Fix bug with overflowing C-shift in division routine.Damien George2016-05-08
| | | | | | | When DIG_SIZE=32, a uint32_t is used to store limbs, and no normalisation is needed because the MSB is already set, then there will be left and right shifts (in C) by 32 of a 32-bit variable, leading to undefined behaviour. This patch fixes this bug.
* py/repl: If there're no better alternatives, try to complete "import".Paul Sokolovsky2016-05-08
| | | | | | Also do that only for the first word in a line. The idea is that when you start up interpreter, high chance that you want to do an import. With this patch, this can be achieved with "i<tab>".
* py/runtime: Properly handle passing user mappings to ** keyword args.Damien George2016-05-07
|
* py/objstr: Binary type of str/bytes for buffer protocol is 'B'.Damien George2016-05-07
| | | | | | The type is an unsigned 8-bit value, since bytes objects are exactly that. And it's also sensible for unicode strings to return unsigned values when accessed in a byte-wise manner (CPython does not allow this).
* py/obj: Add warning note about get_array return value and GC blocks.Damien George2016-05-04
|
* py/modcollections: Rename module name have "u" prefix for consistency.Paul Sokolovsky2016-05-02
|
* py/modio: Rename module name to "uio" for consistency with other modules.Paul Sokolovsky2016-05-02
|
* extmod/modwebrepl: Module to handle WebREPL protocol.Paul Sokolovsky2016-04-29
| | | | | | | While just a websocket is enough for handling terminal part of WebREPL, handling file transfer operations requires demultiplexing and acting upon, which is encapsulated in _webrepl class provided by this module, which wraps a websocket object.
* py/vm: "yield from" didn't handle MP_OBJ_STOP_ITERATION optimization.Paul Sokolovsky2016-04-28
| | | | E.g. crashed when yielding from already stopped generators.
* py/mkrules.mk: Typo fixes in comments.Paul Sokolovsky2016-04-26
|
* py/emitnative: Use MP_OBJ_NEW_SMALL_INT instead of manual bit shifting.Damien George2016-04-26
|
* py/obj.h: When constructing a small-int cast to mp_uint_t for bit-shift.Damien George2016-04-26
| | | | | | The C standard says that left-shifting a signed value (on the LHS of the operator) is undefined. So we cast to an unsigned integer before the shift. gcc does not issue a warning about this, but clang does.
* py/makeqstrdefs.py: Windows compatibility.stijn2016-04-25
| | | | | | | | | | - msvc preprocessor output contains full paths with backslashes so the ':' and '\' characters needs to be erased from the paths as well - use a regex for extraction of filenames from preprocessor output so it can handle both gcc and msvc preprocessor output, and spaces in paths (also thanks to a PR from @travnicekivo for part of that regex) - os.rename will fail on windows if the destination file already exists, so simply attempt to delete that file first
* py/makeqstrdefs.py: Remove unused function/variable/import.stijn2016-04-25
|
* py/runtime_utils: Fix nanbox build.Paul Sokolovsky2016-04-25
|
* py: Move call_function_*_protected() functions to py/ for reuse.Paul Sokolovsky2016-04-25
| | | | They almost certainly needed by any C code which calls Python callbacks.
* py/mkrules.mk: Remove obsolete rules for auto qstr generation.Damien George2016-04-22
|
* py/mkenv.mk: Remove -s and -S args from PYTHON variable.Damien George2016-04-21
| | | | | | Qstr auto-generation is now much faster so this optimisation for start-up time is no longer needed. And passing "-s -S" breaks some things, like stmhal's "make deploy".
* py: Fix bug passing a string as a keyword arg in a dict.Damien George2016-04-21
| | | | Addresses issue #1998.
* py: Divide "split" and "cat" phases of qstr extraction for better efficiency.Paul Sokolovsky2016-04-19
| | | | | | | | | E.g. for stmhal, accumulated preprocessed output may grow large due to bloated vendor headers, and then reprocessing tens of megabytes on each build make take couple of seconds on fast hardware (=> potentially dozens of seconds on slow hardware). So instead, split once after each change, and only cat repetitively (guaranteed to be fast, as there're thousands of lines involved at most).
* py/makeqstrdefs.py: Process only CPP line-numbering info.Paul Sokolovsky2016-04-19
| | | | Not stuff like "#pragma", etc.
* py/mkrules.mk: Fix Bashism.Paul Sokolovsky2016-04-19
|
* py/mkrules.mk: Cleanup command passed to shell.Paul Sokolovsky2016-04-19
|
* py/mkrules.mk: Try to detect and emulate make -B behavior for qstr extraction.Paul Sokolovsky2016-04-19
| | | | | | If make -B is run, the rule is run with $? empty. Extract fron all file in this case. But this gets fragile, really "make clean" should be used instead with such build complexity.
* py: Rework QSTR extraction to work in simple and obvious way.Paul Sokolovsky2016-04-19
| | | | | | | | | | | | When there're C files to be (re)compiled, they're all passed first to preprocessor. QSTR references are extracted from preprocessed output and split per original C file. Then all available qstr files (including those generated previously) are catenated together. Only if the resulting content has changed, the output file is written (causing almost global rebuild to pick up potentially renumbered qstr's). Otherwise, it's not updated to not cause spurious rebuilds. Related make rules are split to minimize amount of commands executed in the interim case (when some C files were updated, but no qstrs were changed).
* py/mkenv.mk: Optimize Python startup type during make process.Paul Sokolovsky2016-04-17
| | | | By skipping loading site.py, etc.
* py/frozenmod: Pass the source name of the frozen module to the lexer.Damien George2016-04-17
| | | | | This allows for better error messages, since the name of the file (sans .py) can now be printed when an exception occurs within a frozen script.
* py/mkrules.mk: Suppress line-no output from CPP for qstr auto-gen.Jan Čapek2016-04-16
|
* py/py.mk: Add makefile variable for qstr autogeneration control.Jan Čapek2016-04-16
| | | | | | | - any architecture may explicitely build with qstring make QSTR_AUTOGEN_DISABLE=1 autogeneration disabled and provide its own list of qstrings by the standard mechanisms (qstrdefsport.h).
* py/mkrules.mk: Add mpconfig[port].h dependency to qstr generating rule.Jan Čapek2016-04-16
|
* py: Add rules for automated extraction of qstrs from sources.Jan Čapek2016-04-16
| | | | | | | | | | | | | | | | | | | | | - add template rule that converts a specified source file into a qstring file - add special rule for generating a central header that contains all extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED variable. Each platform appends a list of sources that may contain qstrings into a new build variable: SRC_QSTR. Any autogenerated prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable. - remove most qstrings from py/qstrdefs, keep only qstrings that contain special characters - these cannot be easily detected in the sources without additional annotations - remove most manual qstrdefs, use qstrdef autogen for: py, cc3200, stmhal, teensy, unix, windows, pic16bit: - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.) - remove all port specific qstrdefs except for special strings - append sources for qstr generation in platform makefiles (SRC_QSTR)
* py/makeqstrdefs: Add script to automate extraction of qstr from sources.Pavel Moravec2016-04-16
| | | | | | | | | | This script will search for patterns of the form Q(...) and generate a list of them. The original code by Pavel Moravec has been significantly simplified to remove the part that searched for C preprocessor directives (eg #if). This is because all source is now run through CPP before being fed into this script.
* py/map: Change hash-table allocation policy to be less aggressive.Damien George2016-04-15
| | | | | | | | | | Small hash tables (eg those used in user class instances that only have a few members) now only use the minimum amount of memory necessary to hold the key/value pairs. This can reduce performance for instances that have many members (because then there are many reallocations/rehashings of the table), but helps to conserve memory. See issue #1760.
* py: Declare help, input, open builtins in core.Paul Sokolovsky2016-04-15
| | | | These are *defined* per-port, but why redeclare them again and again.
* py/makeqstrdata: Add special case to handle \n qstr.Damien George2016-04-14
|
* py/makeqstrdata: Reinstate Python2 compatibility.Damien George2016-04-14
|
* py/makeqstrdata: Fix rendering of qstrs that have non-printable ASCII.Damien George2016-04-14
| | | | | The qstr data needs to be turned into a proper C string so non-ASCII chars must be properly escaped according to C rules.
* py: Simplify "and" action within parser by making ident-rules explicit.Damien George2016-04-14
| | | | | | | | | | Most grammar rules can optimise to the identity if they only have a single argument, saving a lot of RAM building the parse tree. Previous to this patch, whether a given grammar rule could be optimised was defined (mostly implicitly) by a complicated set of logic rules. With this patch the definition is always specified explicitly by using "and_ident" in the rule definition in the grammar. This simplifies the logic of the parser, making it a bit smaller and faster. RAM usage in unaffected.
* py/makeqstrdata: Add more names for escaped chars and esc non-printable.Damien George2016-04-13
| | | | | Non-printable characters are escaped as 0xXX, where XX are the hex digits of the character value.
* py: Add ability to have frozen persistent bytecode from .mpy files.Damien George2016-04-13
| | | | | | | The config variable MICROPY_MODULE_FROZEN is now made of two separate parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This allows to have none, either or both of frozen strings and frozen mpy files (aka frozen bytecode).
