* py/compile: Fix async-for/async-with to work with simpler exc on stack.Damien George2016-09-28
| | | | | There is now just the exception instance on the stack when an exception is raised, not the full (type, exc, traceback).
* tests/basics: Add test for set.difference_update with arg being itself.Damien George2016-09-28
|
* py/objset: Ensure that use of frozenset.update raises an exception.Damien George2016-09-28
|
* py/objset: Use mp_check_self() to check args of set/frozenset methods.Damien George2016-09-28
| | | | | | | | | Following how other objects work, set/frozenset methods should use the mp_check_self() macro to check the type of the self argument, because in most cases this check can be a null operation. Saves about 100-180 bytes of code for builds with set and frozenset enabled.
* py/objfun: Use if instead of switch to check return value of VM execute.Damien George2016-09-27
| | | | It's simpler and improves code coverage.
* py/objfun: Remove unnecessary check for viper fun with 5 or more args.Damien George2016-09-27
| | | | | The native emitter/compiler restricts viper functions to 4 args, so there is no need for an extra check in the dynamic dispatch.
* stmhal/modmachine: Fix clearing of reset-cause flags.Damien George2016-09-27
| | | | | | | To reset the flags we should write to the single bit only, not the entire register (otherwise all other settings in the register are cleared). Fixes #2457.
* py/emitbc: Remove/refactor unreachable code, to improve coverage.Damien George2016-09-27
|
* py/objstr: Remove unreachable function used only for terse error msgs.Damien George2016-09-27
|
* tests/float: Add test for parsing a float from an empty string.Damien George2016-09-27
|
* esp8266: Add uos.statvfs() to get filesystem status.Alex March2016-09-27
|
* tests/extmod/vfs_fat_ramdisk: Add test for VFS.statvfs().Alex March2016-09-27
|
* extmod/vfs_fat: Add fat_vfs_statvfs(), reused from stmhal.Alex March2016-09-27
|
* py/modmicropython: Add micropython.const, alias for identity function.Damien George2016-09-27
| | | | | | | | | Having a micropython.const identity function, and writing "from micropython import const" at the start of scripts that use the const feature, allows to write scripts which are compatible with CPython, and with uPy builds that don't include const optimisation. This patch adds such a function and updates the tests to do the import.
* tests/cmdline/cmd_showbc: Fix test now that 1 value is stored on stack.Damien George2016-09-27
| | | | | This corresponds to the change in the way exception values are stored on the Python value stack.
* py/vm: Use MP_OBJ_FROM_PTR to cast a type to an object.Damien George2016-09-27
|
* tests/micropython: Add tests for const names being replaced in parser.Damien George2016-09-27
|
* tests/basics: Add test case for overflowing Py stack in try-finally.Damien George2016-09-27
|
* py: Only store the exception instance on Py stack in bytecode try block.Damien George2016-09-27
| | | | | | | | | | | | | | | | | | | | When an exception is raised and is to be handled by the VM, it is stored on the Python value stack so the bytecode can access it. CPython stores 3 objects on the stack for each exception: exc type, exc instance and traceback. uPy followed this approach, but it turns out not to be necessary. Instead, it is enough to store just the exception instance on the Python value stack. The only place where the 3 values are needed explicitly is for the __exit__ handler of a with-statement context, but for these cases the 3 values can be extracted from the single exception instance. This patch removes the need to store 3 values on the stack, and instead just stores the exception instance. Code size is reduced by about 50-100 bytes, the compiler and VM are slightly simpler, generate bytecode is smaller (by 2 bytes for each try block), and the Python value stack is reduced in size for functions that handle exceptions.
* extmod/uzlib/: Update uzlib to v2.0.3.Paul Sokolovsky2016-09-24
| | | | Fixes for more pedantic warnings.
* tests/uzlib_decompio_gz: Test for DecompIO with gzip bitstream.Paul Sokolovsky2016-09-24
|
* extmod/moduzlib: DecompIO: Add support for gzip-formatted streams.Paul Sokolovsky2016-09-24
| | | | | This uses extension introduced in CPython 3.5: if wbits (dictionary size code) has value 16 + 8..15, it means that gzip-formatted stream expected.
* extmod/uzlib: Add tinfgzip.c (gzip header parsing) from upstream.Paul Sokolovsky2016-09-24
|
* tools: Update upip to 0.8. Fixes IPv6 support.Paul Sokolovsky2016-09-23
|
* py/py.mk: Add support for building modussl_mbedtls.Paul Sokolovsky2016-09-23
|
* py/parse: Only replace constants that are standalone identifiers.Damien George2016-09-23
| | | | | | This fixes constant substitution so that only standalone identifiers are replaced with their constant value (if they have one). I.e. don't replace NAME in expressions like obj.NAME or NAME = expr.
* docs/library/machine: Update description of disable/enable IRQ funcs.Damien George2016-09-23
|
* py: Update opcode format table because 3 opcodes were removed, 1 added.Damien George2016-09-23
| | | | | LIST_APPEND, MAP_ADD and SET_ADD have been removed, and STORE_COMP has been added in adaf0d865cd6c81fb352751566460506392ed55f.
* py: Shrink mp_arg_t struct by using reduced-size integer members.Damien George2016-09-23
| | | | | | | | | qstrs ids are restricted to fit within 2 bytes already (eg in persistent bytecode) so it's safe to use a uint16_t to store them in mp_arg_t. And the flags member only needs a maximum of 2 bytes so can also use uint16_t. Savings in code size can be significant when many mp_arg_t structs are used for argument parsing. Eg, this patch reduces stmhal by 480 bytes.
* extmod/modussl_mbedtls: Add server_hostname param for wrap_socket().Paul Sokolovsky2016-09-23
| | | | | In CPython, module-level .wrap_socket() function actually doesn't accept (or document) this param, only SSLContext.wrap_socket() has.
* extmod/machine_i2c: Add clock stretching support.Radomir Dopieralski2016-09-22
| | | | | | | | | | | | | | When the clock is too fast for the i2c slave, it can temporarily hold down the scl line to signal to the master that it needs to wait. The master should check the scl line when it is releasing it after transmitting data, and wait for it to be released. This change has been tested with a logic analyzer and an i2c slace implemented on an atmega328p using its twi peripheral, clocked at 8Mhz. Without the change, the i2c communication works up to aboy 150kHz frequency, and above that results in the slave stuck in an unresponsive state. With this change, communication has been tested to work up to 400kHz.

* py/stream: Remove unnecessary check for NULL return from vstr_extend.Damien George2016-09-22
| | | | | vstr_extend will now only return NULL if the vstr is a fixed buffer, which in this case it is not.
* README: Remove issue-stats badges, the service is no longer available.Damien George2016-09-22
| | | | | | | The issue-stats service is not well maintained and likely the situation won't improve in the future. See: https://github.com/hstove/issue_stats/issues/41 https://github.com/hstove/issue_stats/issues/46
* extmod/modussl_mbedtls: Use 2-component include paths.Paul Sokolovsky2016-09-22
| | | | | This is required to use mbedTLS versions from various sources, e.g. mainline vs embedded into Zephyr RTOS.
* extmod/modussl_mbedtls: Implement key= and cert= args to wrap_socket().Paul Sokolovsky2016-09-22
| | | | | Unlike standard keyfile= and certfile=, these accept byte buffer objects (to not depend on FS implementation).
* extmod/modubinascii: Fix crc32() function on 32-bit platforms.Pavol Rusnak2016-09-21
|
* extmod/uctypes: Allow full 32-bit address range.Stefan Agner2016-09-21
| | | | | Use mp_obj_int_get_truncated to allow the full 32-bit address range as first parameter.
* extmod/modussl_mbedtls: Initial implementation of mbedTLS ussl module.Paul Sokolovsky2016-09-21
|
* all: Remove 'name' member from mp_obj_module_t struct.Damien George2016-09-22
| | | | One can instead lookup __name__ in the modules dict to get the value.
* stmhal: Use attribute to avoid inlining.Stefan Agner2016-09-20
| | | | | Use MP_NOINLINE macro to avoid inlining of init_flash_fs. This helps to keep stack usage of main() low.
* py/builtinimport: Fix nanbox build after change to better handle -m modules.Paul Sokolovsky2016-09-20
|
* builtinimport: add the module specified by -m to sys.modules as '__main__'Delio Brignoli2016-09-20
|
* esp8266: Extend system microsecond counter to 64-bits; use in ticks_ms.Damien George2016-09-20
| | | | So now ticks_ms can count up to the full 30 bits. Fixes issue #2412.
* travis: Run feature and coverage test for precompiled mpy files.Damien George2016-09-20
|
* tests/run-tests: Add --via-mpy option to run test from precompiled code.Damien George2016-09-20
| | | | | With mpy-cross built, tests can now be run by first compiling them to .mpy files, and then executing the .mpy file. Usage: ./run-tests --via-mpy
* tests: Get cmdline verbose tests running again.Damien George2016-09-20
| | | | | The showbc function now no longer uses the system printf so works correctly.
