No functional changes. 2017-10-30T04:25:32+00:00 Eric Poulsen eric@zyxod.com 2017-10-27T04:17:35+00:00 urn:sha1:74ec52d85758ad9da7a3abb24257511b22d74964 Per the comment found here https://github.com/micropython/micropython-esp32/issues/209#issuecomment-339855157, this patch adds finaliser code to prevent memory leaks from ussl objects, which is especially useful when memory for a ussl context is allocated outside the uPy heap. This patch is in-line with the finaliser code found in many modsocket implementations for various ports. This feature is configured via MICROPY_PY_USSL_FINALISER and is disabled by default because there may be issues using it when the ussl state *is* allocated on the uPy heap, rather than externally. 2017-10-27T07:01:25+00:00 Damien George damien.p.george@gmail.com 2017-10-27T07:01:25+00:00 urn:sha1:c64eb4f8ce20b025bb5762d9ce6e093d15a19dce VLAs can be expensive on stack usage due to stack alignment requirements, and also the fact that extra local variables are needed to track the dynamic size of the stack. So using fixed-size arrays when possible can help to reduce code size and stack usage. In this particular case, the maximum value of n_args in the VLA is 2 and so it's more efficient to just allocate this array with a fixed size. This reduces code size by around 30 bytes on Thumb2 and Xtensa archs. It also reduces total stack usage of the function: on Thumb2 the usage with VLA is between 40 and 48 bytes, which is reduced to 32; on Xtensa, VLA usage is between 64 and 80 bytes, reduced to 32; on x86-64 it's at least 88 bytes reduced to 80. 2017-10-24T11:39:36+00:00 Damien George damien.p.george@gmail.com 2017-10-24T11:39:36+00:00 urn:sha1:f4059dcc0c5251256a53fcb49f56fdda6e879341 This is the established way of doing it and reduces code size by a little bit. 2017-10-19T03:10:17+00:00 Damien George damien.p.george@gmail.com 2017-10-19T03:10:17+00:00 urn:sha1:9725a654bdfc4ec0b7d6bc6aa3f4365f0825c5f3 Without this the board will crash when deactivating a stream that doesn't have a close() method (eg UART) or that raises an exception within the method (eg user-defined function). 2017-10-13T09:01:57+00:00 Damien George damien.p.george@gmail.com 2017-10-13T09:01:57+00:00 urn:sha1:37282f8fc135a16ff36e2afe0de907cbde531ed0 The uos.dupterm() signature and behaviour is updated to reflect the latest enhancements in the docs. It has minor backwards incompatibility in that it no longer accepts zero arguments. The dupterm_rx helper function is moved from esp8266 to extmod and generalised to support multiple dupterm slots. A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM config macro to an integer, being the number of slots it wants to have; 0 means to disable the dupterm feature altogether. The unix and esp8266 ports are updated to work with the new interface and are otherwise unchanged with respect to functionality. 2017-10-04T01:37:50+00:00 Damien George damien.p.george@gmail.com 2017-10-04T01:37:50+00:00 urn:sha1:a3dc1b1957d2c96d7c60c2c629c95077b03488a1 Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed. 2017-10-02T21:20:10+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-10-02T21:12:06+00:00 urn:sha1:aba1f9167a7db1c0f19d2ab44a8dbfe5c18cc062 2017-10-02T18:20:47+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-10-02T18:20:47+00:00 urn:sha1:c9a0b2a8182abcb87afa1d8766d74ca8fa87cb34 2017-09-24T07:19:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-24T07:19:24+00:00 urn:sha1:4a314a6f63c7157a824aa98c01009a8fbafb7475 Allow literal minus in char classes to be in trailing position, e.g. [a-c-]. (Previously, minus was allowed only at the start.) This increases ARM Thumb2 code size by 8 bytes.
