| * extmod: Add machine time_pulse_us function (at C and Python level).Damien George2016-05-31
| | | | | | | | The C implementation is taken from the DHT driver.
| * extmod/virtpin: Initial implementation of open-ended C-level Pin interface.Paul Sokolovsky2016-05-27
| | | | | | | | | | | | | | | | | | Using usual method of virtual method tables. Single virtual method, ioctl, is defined currently for all operations. This universal and extensible vtable-based method is also defined as a default MPHAL GPIO implementation, but a specific port may override it with its own implementation (e.g. close-ended, but very efficient, e.g. avoiding virtual method dispatch).

The ESP8266 port has many improvements and additions, including: websocket and webrepl modules, deep-sleep mode, reading on UART, enhanced I2C support, enhanced network configuration, full sequence of start-up scripts (built-in _boot.py, boot.py and main.py), improved filesystem support with automatic flash-size detection as well as documentation and a tutorial. Known issues with ESP8266 port are: - Basic SSL support is available but it works only with relatively short data lengths (a few kilobytes). - WebREPL over SSL is not supported. - Only 5 or so WebREPL sessions in succession can be started (including file transfer sessions), after that the board requires a hard reset. - File transfer over WebREPL has issues with large files (above a few tens of kilobytes). - By design, only one concurrent WebREPL connection is supported. - Soft reset doesn't reset the network stack. In addition to ESP8266 support, this release brings frozen bytecode which allows to compile bytecode offline and link it into the firmware, completely eliminating the need for compilation (and the associated RAM usage) at runtime. Basic async/await syntax is now supported, and qstrs are now auto-generated in the build system. A detailed list of changes is given below. README: - explicitly point to required dependencies section - promote "docs" and "tests" to "major components" - mention support "async" keyword from Python 3.5 ACKNOWLEDGEMENTS: - add list of 842 backers from the ESP8266 campaign py core: - modbuiltins: add comment about setting "_" special var - add async/await/async for/async with syntax - fix constant folding and inline-asm to work with new async grammar - emitglue: move typedef of mp_raw_code_t from .c to .h file -

| * 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: 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/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: 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)
| * extmod: Add generic machine.I2C class, with bit-bang I2C.Damien George2016-04-12

* extmod/modurandom: Add "urandom" module.Paul Sokolovsky2016-01-17
| | | | | | | | Seedable and reproducible pseudo-random number generator. Implemented functions are getrandbits(n) (n <= 32) and seed(). The algorithm used is Yasmarang by Ilya Levin: http://www.literatecode.com/yasmarang
* extmod/moduos_dupterm: Make uos.dupterm() implementation reusable.Paul Sokolovsky2016-01-01
| | | | | That's just function which sets/gets dup terminal object, and can be easily reused across ports.
* py/objpolyiter: Implement instance-polymorphic iterator type.Paul Sokolovsky2015-12-14
| | | | | | | This allows to have single itertaor type for various internal iterator types (save rodata space by not having repeating almost-empty type structures). It works by looking "iternext" method stored in particular object instance (should be first object field after "base").
* unix: Move modmachine into unix directoryDave Hylands2015-12-13
| | | | | This leaves behind the common functionality in extmod/machine_mem.c which can be used by all ports.
* extmod: Move fsusermount.c from stmhal for cross-port reuse.Paul Sokolovsky2015-11-25

* extmod/modlwip: slip: Use stream protocol and be port-independent.Paul Sokolovsky2015-10-27
| | | | | Based on the original patch by Galen Hazelwood: https://github.com/micropython/micropython/pull/1517 .
* 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.
* modussl: SSL socket wrapper module based on axTLS.Paul Sokolovsky2015-10-06
|
* unix-cpy: Remove unix-cpy. It's no longer needed.Damien George2015-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unix-cpy was originally written to get semantic equivalent with CPython without writing functional tests. When writing the initial implementation of uPy it was a long way between lexer and functional tests, so the half-way test was to make sure that the bytecode was correct. The idea was that if the uPy bytecode matched CPython 1-1 then uPy would be proper Python if the bytecodes acted correctly. And having matching bytecode meant that it was less likely to miss some deep subtlety in the Python semantics that would require an architectural change later on. But that is all history and it no longer makes sense to retain the ability to output CPython bytecode, because: 1. It outputs CPython 3.3 compatible bytecode. CPython's bytecode changes from version to version, and seems to have changed quite a bit in 3.5. There's no point in changing the bytecode output to match CPython anymore. 2. uPy and CPy do different optimisations to the bytecode which makes it harder to match. 3. The bytecode tests are not run. They were never part of Travis and are not run locally anymore. 4. The EMIT_CPYTHON option needs a lot of extra source code which adds heaps of noise, especially in compile.c. 5. Now that there is an extensive test suite (which tests functionality) there is no need to match the bytecode. Some very subtle behaviour is tested with the test suite and passing these tests is a much better way to stay Python-language compliant, rather than trying to match CPy bytecode.
* py: Rebuild port if mpconfigport.mk changed (if any).Paul Sokolovsky2015-06-11
| | | | | | | | mpconfigport.mk contains configuration options which affect the way MicroPython is linked. In this regard, it's "stronger" configuration dependency than even mpconfigport.h, so if we rebuild everything on mpconfigport.h change, we certianly should of that on mpconfigport.mk change too.
* py: Wrap qstr defs in quotes to protect from C preprocessor.Damien George2015-05-30
| | | | | | | | | This patch converts Q(abc) to "Q(abc)" to protect the abc from the C preprocessor, then converts back after the preprocessor is finished. So now we can safely put includes in mpconfig(port).h, and also preprocess qstrdefsport.h (latter is now done also in this patch). Addresses issue #1252.
* objsingleton: New home for Ellipsis and NotImplemented.Paul Sokolovsky2015-05-05
| | | | | | | Having NotImplemented as MP_OBJ_SENTINEL turned out to be problematic (it needs to be checked for in a lot of places, otherwise it'll crash as would pass MP_OBJ_IS_OBJ()), so made a proper singleton value like Ellipsis, both of them sharing the same type.
* modmachine: Add new module to access hardware, starting with physical memory.Paul Sokolovsky2015-05-04
| | | | | Refactored from "stm" module, provides mem8, mem16, mem32 objects with array subscript syntax.
* py: Replace py-version.sh with makeversionhdr.py, written in Python.Damien George2015-04-28
| | | | Also rename py-version.h to mpversion.h for consistency with mpconfig.h.
* 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, compiler: Remove emit_pass1 code, using emit_bc to do its job.Damien George2015-03-26
| | | | | | | | | | | | | | | First pass for the compiler is computing the scope (eg if an identifier is local or not) and originally had an entire table of methods dedicated to this, most of which did nothing. With changes from previous commit, this set of methods can be removed and the methods from the bytecode emitter used instead, with very little modification -- this is what is done in this commit. This factoring has little to no impact on the speed of the compiler (tested by compiling 3763 Python scripts and timing it). This factoring reduces code size by about 270-300 bytes on Thumb2 archs, and 400 bytes on x86.
* 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: Implement very simple frozen modules support.Paul Sokolovsky2015-01-20
| | | | | Only modules (not packages) supported now. Source modules can be converted to frozen module structures using tools/make-frozen.py script.
* 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.
* py: Add basic framework for issuing compile/runtime warnings.Paul Sokolovsky2015-01-01

* py: Allow builtins to be overridden.Damien George2014-12-09
| | | | | | | | | | | | | | 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.

* py: Fix order-only dependencies in mkrules.mk and py.mk.Sven Wegener2014-11-06
| | | | | | | | | Currently compilation sporadically fails, because the automatic dependency gets created *during* the compilation of objects. OBJ is a auperset of PY_O and the dependencies apply to all objects. Signed-off-by: Sven Wegener <sven.wegener@stealer.net>
* py: Add order-only dependency for py-version.hSven Wegener2014-11-05
| | | | | | Else the directory might not exist. Signed-off-by: Sven Wegener <sven.wegener@stealer.net>
