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 2017-04-12T03:22:21+00:00 Damien George damien.p.george@gmail.com 2017-04-06T02:09:01+00:00 urn:sha1:816413e4b20ccd463321558458bb63c310712bca The common cases for inheritance are 0 or 1 parent types, for both built-in types (eg built-in exceptions) as well as user defined types. So it makes sense to optimise the case of 1 parent type by storing just the type and not a tuple of 1 value (that value being the single parent type). This patch makes such an optimisation. Even though there is a bit more code to handle the two cases (either a single type or a tuple with 2 or more values) it helps reduce overall code size because it eliminates the need to create a static tuple to hold single parents (eg for the built-in exceptions). It also helps reduce RAM usage for user defined types that only derive from a single parent.

Aligning for mp_obj_t should be sufficient for emergency exceptions, but in general the memory buffer should aligned to the maximum alignment of the machine (eg on a 32-bit machine with mp_obj_t being 4 bytes, a double may not be correctly aligned). This patch fixes a bug for certain nan-boxing builds, where mp_obj_t is 8 bytes and must be aligned to 8 bytes (even though the machine is 32 bit). 2017-02-24T16:47:02+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-24T16:47:02+00:00 urn:sha1:aef0586ee101aa1ba9f0cda38f23b0fdef3312a6 2017-02-16T05:51:17+00:00 Damien George damien.p.george@gmail.com 2017-02-16T05:38:14+00:00 urn:sha1:fa5a591757569136a444715cce2248b63ad73512 2017-01-17T06:03:16+00:00 Damien George damien.p.george@gmail.com 2017-01-17T06:03:16+00:00 urn:sha1:5bea080737ee4a22e2a99aa03743cdf4b6396b7d 2016-11-13T23:29:09+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-11-13T23:23:30+00:00 urn:sha1:c3d96d387c461c25ca3298dfa73d2a4efb45f1e7 We allow 'exc.__traceback__ = None' assignment as a low-level optimization of pre-allocating exception instance and raising it repeatedly - this avoids memory allocation during raise. However, uPy will keep adding traceback entries to such exception instance, so before throwing it, traceback should be cleared like above. 'exc.__traceback__ = None' syntax is CPython compatible. However, unlike it, reading that attribute or setting it to any other value is not supported (and not intended to be supported, again, the only reason for adding this feature is to allow zero-memalloc exception raising). 2016-05-12T13:27:52+00:00 Damien George damien.p.george@gmail.com 2016-05-12T13:27:52+00:00 urn:sha1:9a9249964155f333131bbd728ffc755e80dc68a2 OSError's are now printed like: OSError: [Errno 1] EPERM but only if the string corresponding to the errno is found.
