Thanks to @rkojedzinszky for the initial patch, PR #3457. extmod/modlwip: Update to work with lwIP v2.0. 2018-05-17T02:58:34+00:00 Damien George damien.p.george@gmail.com 2018-05-17T02:58:34+00:00 urn:sha1:9c2044717c8852105df25746a8a7b873fbfc3609 lwIP v2.0.3 has been tested with this lwip module and it works very well. extmod/modlwip: In ioctl handle case when socket is in an error state. 2018-05-04T05:15:04+00:00 Damien George damien.p.george@gmail.com 2018-05-04T05:15:04+00:00 urn:sha1:318f874cda22567a55bb004434ed0ec891fd7d61 Using MP_STREAM_POLL_HUP for ERR_RST state follows how *nix handles this case. extmod/modlwip: Check if getaddrinfo() constraints are supported or not. 2018-04-23T06:38:20+00:00 Damien George damien.p.george@gmail.com 2018-04-23T06:38:20+00:00 urn:sha1:bdff68db9c1f7e35d0600841647cffac4b1d9ef0 In particular don't issue a warning if the passed-in constraints are actually supported because they are the default values. py/stream: Switch stream close operation from method to ioctl. 2018-04-10T03:41:32+00:00 Damien George damien.p.george@gmail.com 2018-03-07T06:48:53+00:00 urn:sha1:cf31d384f1d2ca09f817f154892eaa6860c10144 This patch moves the implementation of stream closure from a dedicated method to the ioctl of the stream protocol, for each type that implements closing. The benefits of this are: 1. Rounds out the stream ioctl function, which already includes flush, seek and poll (among other things). 2. Makes calling mp_stream_close() on an object slightly more efficient because it now no longer needs to lookup the close method and call it, rather it just delegates straight to the ioctl function (if it exists). 3. Reduces code size and allows future types that implement the stream protocol to be smaller because they don't need a dedicated close method. Code size reduction is around 200 bytes smaller for x86 archs and around 30 bytes smaller for the bare-metal archs. extmod/modlwip: Commit TCP out data to lower layers if buffer gets full. 2017-11-24T04:52:32+00:00 Damien George damien.p.george@gmail.com 2017-10-31T02:50:08+00:00 urn:sha1:48f6990fbc54ac29b15fa765d431244d1dcb5f21 Dramatically improves TCP sending throughput because without an explicit call to tcp_output() the data is only sent to the lower layers via the lwIP slow timer which (by default) ticks every 500ms. all: Use NULL instead of "" when calling mp_raise exception helpers. 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. all: Remove inclusion of internal py header files. 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.
