* tools/gen-cpydiff.py: configurable CPython and micropython executablesKrzysztof Blazewicz2017-02-27
|
* docs/Makefile: define and use PYTHON as the interpreter for CPYDIFFKrzysztof Blazewicz2017-02-27
| | | | | | User can override PYTHON executable before running script, gen-cpydiff.py works only with Python3 and most systems register its executable as 'python3'.
* minimal: Add ability and description to build without the compiler.Damien George2017-02-27
|
* lib/utils/pyexec: Allow to compile when the uPy compiler is disabled.Damien George2017-02-27
|
* docs/uhashlib: Provide port-neutral description.Paul Sokolovsky2017-02-26
| | | | TODO: Remove WiPy-specific chunks.
* extmod/modurandom: Use mp_raise_ValueError().Paul Sokolovsky2017-02-24
| | | | | For the standard unix x86_64 build, this saves 11 bytes on object file level, but no difference in executable size due to (bloaty) code alignment.
* py/runtime: mp_raise_msg(): Accept NULL argument for message.Paul Sokolovsky2017-02-24
| | | | | | | | In this case, raise an exception without a message. This would allow to shove few code bytes comparing to currently used mp_raise_msg(..., "") pattern. (Actual savings depend on function code alignment used by a particular platform.)
* esp8266/mpconfigport.h: Enable help('modules') feature.Damien George2017-02-24
|
* drivers/display/lcd160cr: Fix bug with save_to_flash method.Damien George2017-02-24
|
* cc3200/moduos: Remove uos.sep, as it's strictly optional.Paul Sokolovsky2017-02-23
| | | | | | In MicroPython, the path separator is guaranteed to be "/", extra unneeded things take precious code space (in the port which doesn't have basic things like floating-port support).
* py/parse: Simplify handling of errors by raising them directly.Damien George2017-02-24
| | | | | | | | | | | | | | | The parser was originally written to work without raising any exceptions and instead return an error value to the caller. But it's now required that a call to the parser be wrapped in an nlr handler, so we may as well make use of that fact and simplify the parser so that it doesn't need to keep track of any memory errors that it had. The parser anyway explicitly raises an exception at the end if there was an error. This patch simplifies the parser by letting the underlying memory allocation functions raise an exception if they fail to allocate any memory. And if there is an error parsing the "<id> = const(<val>)" pattern then that also raises an exception right away instead of trying to recover gracefully and then raise.
* py: Create str/bytes objects in the parser, not the compiler.Damien George2017-02-24
| | | | | | | | | | | | | | | | | | Previous to this patch any non-interned str/bytes objects would create a special parse node that held a copy of the str/bytes data. Then in the compiler this data would be turned into a str/bytes object. This actually lead to 2 copies of the data, one in the parse node and one in the object. The parse node's copy of the data would be freed at the end of the compile stage but nevertheless it meant that the peak memory usage of the parse/compile stage was higher than it needed to be (by an amount equal to the number of bytes in all the non-interned str/bytes objects). This patch changes the behaviour so that str/bytes objects are created directly in the parser and the object stored in a const-object parse node (which already exists for bignum, float and complex const objects). This reduces peak RAM usage of the parse/compile stage, simplifies the parser and compiler, and reduces code size by about 170 bytes on Thumb2 archs, and by about 300 bytes on Xtensa archs.
* tests/micropython: Add test for consts that are bignums.Damien George2017-02-24
|
* py/parse: Allow parser/compiler consts to be bignums.Damien George2017-02-24
| | | | | | | | | | | This patch allows uPy consts to be bignums, eg: X = const(1 << 100) The infrastructure for consts to be a bignum (rather than restricted to small integers) has been in place for a while, ever since constant folding was upgraded to allow bignums. It just required a small change (in this patch) to enable it.
* tools/gen-cpydiff.py: Set the Python import path to find test modules.Damien George2017-02-22
|
* cc3200: Remove socket.timeout class, use OSError(ETIMEDOUT) instead.Damien George2017-02-22
| | | | | | | socket.timeout is a subclass of OSError, and using the latter is more efficient than having a dedicated class. The argument of OSError is ETIMEDOUT so the error can be distinguished from other kinds of OSErrors. This follows how the esp8266 port does it.
* cc3200/mods/modusocket: Init vars to 0 to silence compiler warnings.Damien George2017-02-22
| | | | | Some compilers can't analyse the code to determine that these variables are always set before being used.
* cc3200: Enable uerrno module with short, custom list of error codes.Damien George2017-02-22
| | | | | | | Since we recently replaced the OSError string messages with simple error codes, having the uerrno module gets back some user friendly error messages. The total code size (after removing strings, replacing with uerrno module) is decreased.
* py/moduerrno: Make list of errno codes configurable.Damien George2017-02-22
| | | | | It's configurable by defining MICROPY_PY_UERRNO_LIST. If this is not defined then a default is provided.
* py/moduerrno: Make uerrno.errorcode dict configurable.Damien George2017-02-22
| | | | | | | | It's configured by MICROPY_PY_UERRNO_ERRORCODE and enabled by default (since that's the behaviour before this patch). Without this dict the lookup of errno codes to strings must use the uerrno module itself.
* cc3200: When raising OSError's use MP_Exxx as arg instead of a string.Damien George2017-02-22
|
* cc3200: Convert to using uPy internal errno numbers.Damien George2017-02-22
|
* cc3200: Move wlan socket glue functions from modwlan to modusocket.Damien George2017-02-22
| | | | | It saves about 400 bytes of code space because the functions can now be inlined.
* cc3200: Remove remaining references to std.h.Damien George2017-02-21
|
* drivers/display/lcd160cr: Fix bugs with lcd.get_pixel().Damien George2017-02-21
| | | | Fixes issues #2880 and #2881.
* cc3200/mods/modwlan: Add int casts to silence compiler warnings.Damien George2017-02-21
|
* cc3200/mods/modwlan: Allow antenna diversity to be fully compiled out.Damien George2017-02-21
|
* cc3200/mods/modwlan: Make multi-threaded a proper compile-time option.Damien George2017-02-21
|
* cc3200/mods/modwlan: Remove unused header includes; simplify others.Damien George2017-02-21
|
* cc3200: Remove util/std.h, can just use stdio.h instead.Damien George2017-02-21
|
* cc3200: Use simplelink API instead of emulated BSD API.Damien George2017-02-21
| | | | | Most of cc3200 uses explicit simplelink calls anyway, and this means there are no longer any clashes with macros from the C stdlib.
* cc3200: Move stoupper to ftp.c and define in terms of unichar_toupper.Damien George2017-02-21
| | | | | | ftp.c is the only user of this function so making it static in that file allows it to be inlined. Also, reusing unichar_toupper means we no longer depend on the C stdlib for toupper, saving about 300 bytes of code space.
* tests/cpydiff: Add a test for storing iterable to a list slice.Damien George2017-02-20

* docs: Modify Makefile and indexes to generate cPy-differences pages.Rami Ali2017-02-20

* tools: Add gen-cpydiff.py to generate docs differences.Rami Ali2017-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the a small framework to track differences between uPy and CPython. The framework consists of: - A set of "tests" which test for an individual feature that differs between uPy and CPy. Each test is like a normal uPy test in the test suite, but has a special comment at the start with some meta-data: a category (eg syntax, core language), a human-readable description of the difference, a cause, and a workaround. Following the meta-data there is a short code snippet which demonstrates the difference. See tests/cpydiff directory for the initial set of tests. - A program (this patch) which runs all the tests (on uPy and CPy) and generates nicely-formated .rst documenting the differences. - Integration into the docs build so that everything is automatic, and the differences appear in a way that is easy for users to read/reference (see latter commits). The idea with using this new framework is: - When a new difference is found it's easy to write a short test for it, along with a description, and add it to the existing ones. It's also easy for contributors to submit tests for differences they find. - When something is no longer different the tool will give an error and difference can be removed (or promoted to a proper feature test).
* tests/cpydiff: Add initial set of tests for uPy-CPython differences.Rami Ali2017-02-20
| | | | | | | These tests are intended to fail, as they provide a programatic record of differences between uPy and CPython. They also contain a special comment at the start of the file which has meta-data describing the difference, including known causes and known workarounds.
* py/objlist: For list slice assignment, allow RHS to be a tuple or list.Damien George2017-02-20
| | | | | Before this patch, assigning anything other than a list would lead to a crash. Fixes issue #2886.
* tests/heapalloc_exc_raise.py: Heap alloc test for raising/catching exc.Paul Sokolovsky2017-02-20

* zephyr/README: Network startup issues with frdm_k64f resolved.Paul Sokolovsky2017-02-17
| | | | | But leave a generic warning that users should be aware of Zephyr's limitations/issues for a board they use.
* docs/library/lcd160cr: Mention the valid values for set_power() method.Damien George2017-02-17

* drivers/display/lcd160cr: Use correct variable in set_power().Stephan Brauer2017-02-17
|
* windows/.gitignore: Ignore VC.db and VC.opendb files from VS2015stijn2017-02-17
| | | | | | Since VS2015 update 2 .db files are used for storing browsing info, instead of .sdf files. If users don't specify a location for these files excplicitly they end up in the project directory so ignore them.

* stmhal/main: Remove unnecessary header includes.Damien George2017-02-17
|
* py/grammar: Remove unused rule.Damien George2017-02-17
| | | | | Since the recent changes to string/bytes literal concatenation, this rule is no longer used.
* py/lexer: Convert mp_uint_t to size_t where appropriate.Damien George2017-02-17

* py: Do adjacent str/bytes literal concatenation in lexer, not compiler.Damien George2017-02-17
| | | | | | | | | | | | | | | | | | | | | It's much more efficient in RAM and code size to do implicit literal string concatenation in the lexer, as opposed to the compiler. RAM usage is reduced because the concatenation can be done right away in the tokeniser by just accumulating the string/bytes literals into the lexer's vstr. Prior to this patch adjacent strings/bytes would create a parse tree (one node per string/bytes) and then in the compiler a whole new chunk of memory was allocated to store the concatenated string, which used more than double the memory compared to just accumulating in the lexer. This patch also significantly reduces code size: bare-arm: -204 minimal: -204 unix x64: -328 stmhal: -208 esp8266: -284 cc3200: -224
* py/lexer: Simplify handling of line-continuation error.Damien George2017-02-17
| | | | | | | | | Previous to this patch there was an explicit check for errors with line continuation (where backslash was not immediately followed by a newline). But this check is not necessary: if there is an error then the remaining logic of the tokeniser will reject the backslash and correctly produce a syntax error.
