And alloca was used in the keyword-arg path to temporarily create the array of elements for the namedtuple, which would then be copied to a heap-allocated object (the namedtuple itself). This patch simplifies the code by combining the no-keyword and keyword paths, and removing the need for the alloca by constructing the namedtuple on the heap before populating it. Heap usage in unchanged, stack usage is reduced, use of alloca is removed, and code size is not increased and is actually reduced by between 20-30 bytes for most ports. 2017-06-20T17:56:05+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-06-20T17:56:05+00:00 urn:sha1:30ee7019ca651bce1fe966c1089fe977d51dc92b Fixes for stmhal USB mass storage, lwIP bindings and VFS regressions This release provides an important fix for the USB mass storage device in the stmhal port by implementing the SCSI SYNCHRONIZE_CACHE command, which is now require by some Operating Systems. 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. Changes in code size (in bytes) due to this patch: bare-arm: -16 minimal (x86): -176 unix (x86-64): -320 unix nanbox: -384 stmhal: -64 cc3200: -32 esp8266: -108 2017-03-29T01:56:17+00:00 Damien George damien.p.george@gmail.com 2017-03-25T08:35:08+00:00 urn:sha1:6213ad7f466df12c734dc527993bbb46c9d9eb5c This patch changes mp_uint_t to size_t for the len argument of the following public facing C functions: mp_obj_tuple_get mp_obj_list_get mp_obj_get_array These functions take a pointer to the len argument (to be filled in by the function) and callers of these functions should update their code so the type of len is changed to size_t. For ports that don't use nan-boxing there should be no change in generate code because the size of the type remains the same (word sized), and in a lot of cases there won't even be a compiler warning if the type remains as mp_uint_t. The reason for this change is to standardise on the use of size_t for variables that count memory (or memory related) sizes/lengths. It helps builds that use nan-boxing. 2017-03-24T06:25:25+00:00 Damien George damien.p.george@gmail.com 2017-03-24T06:25:25+00:00 urn:sha1:f4ee1ba9b48870bb0e3d07dcd6fa3913b500b9ec 2017-02-26T00:00:33+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-25T11:19:33+00:00 urn:sha1:062fac1d43d42b35e0ecdaaec124c29b65db7c68 share space with the file system.
