Release v1.9.1: Fixes for stmhal USB mass storage, lwIP bindings and VFS regressions · micropython/micropython (original) (raw)

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:

• 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)

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

examples:

• embedding: use core-provided KeyboardInterrupt object
