There are also fixes for the lwIP bindings to improve non-blocking sockets and error codes. The VFS has some regressions fixed including the ability to statvfs the root. All changes are listed below. py core: - modbuiltins: add core-provided version of input() function - objstr: catch case of negative "maxsplit" arg to str.rsplit() - persistentcode: allow to compile with complex numbers disabled - objstr: allow to compile with obj-repr D, and unicode disabled - modsys: allow to compile with obj-repr D and PY_ATTRTUPLE disabled - provide mp_decode_uint_skip() to help reduce stack usage - makeqstrdefs.py: make script run correctly with Python 2.6 - objstringio: if created from immutable object, follow copy on write policy extmod: - modlwip: connect: for non-blocking mode, return EINPROGRESS - modlwip: fix error codes for duplicate calls to connect() - modlwip: accept: fix error code for non-blocking mode - vfs: allow to statvfs the root directory - vfs: allow "buffering" and "encoding" args to VFS's open() - modframebuf: fix signed/unsigned comparison pendantic warning lib: - libm: use isfinite instead of finitef, for C99 compatibility - utils/interrupt_char: remove support for KBD_EXCEPTION disabled tests: - basics/string_rsplit: add tests for negative "maxsplit" argument - float: convert "sys.exit()" to "raise SystemExit" - float/builtin_float_minmax: PEP8 fixes - basics: convert "sys.exit()" to "raise SystemExit" - convert remaining "sys.exit()" to "raise SystemExit" unix port: - convert to use core-provided version of built-in import() - Makefile: replace references to make with $(MAKE) windows port: - convert to use core-provided version of built-in import() qemu-arm port: - Makefile: adjust object-file lists to get correct dependencies - enable micropython.mem_*() functions to allow more tests stmhal port: - boards: enable DAC for NUCLEO_F767ZI board - add support for NUCLEO_F446RE board - pass USB handler as parameter to allow more than one USB handler - usb: use local USB handler variable in Start-of-Frame handler - usb: make state for USB device private to top-level USB driver - usbdev: for MSC implement SCSI SYNCHRONIZE_CACHE command - convert from using stmhal's input() to core provided version cc3200 port: - convert from using stmhal's input() to core provided version teensy port: - convert from using stmhal's input() to core provided version esp8266 port: - Makefile: replace references to make with $(MAKE) - Makefile: add clean-modules target - convert from using stmhal's input() to core provided version zephyr port: - modusocket: getaddrinfo: Fix mp_obj_len() usage - define MICROPY_PY_SYS_PLATFORM (to "zephyr") - machine_pin: use native Zephyr types for Zephyr API calls docs: - machine.Pin: remove out_value() method - machine.Pin: add on() and off() methods - esp8266: consistently replace Pin.high/low methods with .on/off - esp8266/quickref: polish Pin.on()/off() examples - network: move confusingly-named cc3200 Server class to its reference - uos: deconditionalize, remove minor port-specific details - uos: move cc3200 port legacy VFS mounting functions to its ref doc - machine: sort machine classes in logical order, not alphabetically - network: first step to describe standard network class interface examples: - embedding: use core-provided KeyboardInterrupt object 2017-02-24T14:13:07+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-24T14:13:07+00:00 urn:sha1:12fa5b3a66d6f0034113a56c7d647c7bac5be74c 2017-02-16T08:11:34+00:00 Damien George damien.p.george@gmail.com 2017-02-13T04:44:31+00:00 urn:sha1:e6003f466e6f5b7eddd01740666230b62ab5a872 In these cases the heap is anyway used to create a new object so no real need to use the C stack for iterating. It saves a few bytes of code size. 2017-02-16T07:38:06+00:00 Damien George damien.p.george@gmail.com 2016-01-09T23:14:54+00:00 urn:sha1:ae8d86758631e62466a55d179897d2111c3cb1c1 Allows to iterate over the following without allocating on the heap: - tuple - list - string, bytes - bytearray, array - dict (not dict.keys, dict.values, dict.items) - set, frozenset Allows to call the following without heap memory: - all, any, min, max, sum TODO: still need to allocate stack memory in bytecode for iter_buf. 2017-02-16T05:51:16+00:00 Damien George damien.p.george@gmail.com 2017-02-16T05:16:33+00:00 urn:sha1:68cd3a93f0728b61b0d2407f4ae802806dddce4d 2017-02-02T13:27:56+00:00 Damien George damien.p.george@gmail.com 2017-02-02T13:27:56+00:00 urn:sha1:2486c4ff469fdb69555476e342eadda91a4ceadf 2017-02-02T12:33:49+00:00 Damien George damien.p.george@gmail.com 2017-02-02T12:33:49+00:00 urn:sha1:30cf503e978f7ccfedcaf14b46ab9fb3be065370 2016-10-17T01:17:37+00:00 Damien George damien.p.george@gmail.com 2016-10-17T01:17:37+00:00 urn:sha1:7d0d7215d2575a2d36d34c9a13b58cade0610a28 Saves the following number of bytes of code space: 176 for bare-arm, 352 for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.
