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.

Switching to _estack fixes this by relying on the location from the linker. Fixes #124 2017-04-12T03:52:04+00:00 Damien George damien.p.george@gmail.com 2017-04-12T03:52:04+00:00 urn:sha1:c7e8c6f7dec539aae4ca6445541533bfbc1a1405 If a finaliser raises an exception then it must not propagate through the GC sweep function. This patch protects against such a thing by running finaliser code via the mp_call_function_1_protected call. This patch also adds scheduler lock/unlock calls around the finaliser execution to further protect against any possible reentrancy issues: the memory manager is already locked when doing a collection, but we also don't want to allow any scheduled code to run, KeyboardInterrupts to interupt the code, nor threads to switch. 2016-11-29T22:11:32+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-11-29T22:11:32+00:00 urn:sha1:05c14dfe7809d4ac17c1e18b6ade8786212fc79f This reverts commit 93218281588b42331d83e4aaa45ac1abe4af130b. 2016-11-24T01:31:53+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2016-11-24T01:31:53+00:00 urn:sha1:a8fbad5d8bfd6c0abca8a6759785c61d1f553b3f 2016-11-21T22:11:52+00:00 Scott Shawcroft scott@chickadee.tech 2016-11-03T22:50:59+00:00 urn:sha1:ccbb5e84f980e252f7380d96fcc5c417a8a64523 Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/ It differs from upstream's machine in the following ways: * Python API is identical across ports due to code structure. (Lives in shared-bindings) * Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC). * Documentation lives with code making it easy to ensure they match. * Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut). * All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware. * All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.
