Use mp_obj_int_get_truncated only when you know the argument is a small or big int. 2015-05-04T10:48:40+00:00 Josef Gajdusek atx@atx.name 2015-05-03T18:26:08+00:00 urn:sha1:04ee5983feadc6945e324eb54cd9e7f8c1d6aa8c 2015-01-28T23:43:01+00:00 Damien George damien.p.george@gmail.com 2015-01-28T23:43:01+00:00 urn:sha1:0d3cb6726ddc1bab9fdd11a0aaa259fb436da4b2 This cleans up vstr so that it's a pure "variable buffer", and the user can decide whether they need to add a terminating null byte. In most places where vstr is used, the vstr did not need to be null terminated and so this patch saves code size, a tiny bit of RAM, and makes vstr usage more efficient. When null termination is needed it must be done explicitly using vstr_null_terminate. 2015-01-24T15:07:50+00:00 Damien George damien.p.george@gmail.com 2015-01-24T15:07:50+00:00 urn:sha1:23342c09ff9e7d5ead4905a4692e9646b4bbc2eb accept might raise an exception, in which case the new socket is not fully created. It has a finaliser so will run close() method when GC'd. Before this patch close would try to close an invalid socket. Now fixed. setsockopt took address of stack value which became out of scope. Now fixed. 2015-01-22T00:16:41+00:00 Damien George damien.p.george@gmail.com 2015-01-22T00:16:41+00:00 urn:sha1:8b77e3dd2fd3005bc67bb59a701c6ea2422bf928 It needs to be scanned by GC.

Always use a vstr to build a str/bytes object. If the size is known beforehand then use vstr_init_len to allocate only required memory. Otherwise use vstr_init and the vstr will grow as needed. Then use mp_obj_new_str_from_vstr to create a str/bytes object using the vstr memory. Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes on unix x64. 2015-01-01T21:06:20+00:00 Damien George damien.p.george@gmail.com 2015-01-01T21:06:20+00:00 urn:sha1:2cf6dfa280a8149941aafc852fbaae8bdfc4999e 2014-12-07T17:03:47+00:00 Damien George damien.p.george@gmail.com 2014-12-07T17:03:47+00:00 urn:sha1:d0caaadaeea48e8f76dca3125a2dea3465a58416 Remove include of stm32f4xx_hal.h, replace by include of MICROPY_HAL_H where needed, and make it compile without float support. This makes these 3 modules much more generic and usable by other ports. 2014-12-05T23:13:52+00:00 Damien George damien.p.george@gmail.com 2014-12-05T23:13:52+00:00 urn:sha1:be6d8be91e133e98117025062df0e63aaf87efd2 mp_obj_int_get_truncated is used as a "fast path" int accessor that doesn't check for overflow and returns the int truncated to the machine word size, ie mp_int_t. Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word sized values. Addresses issues #779 and #998. 2014-12-04T18:57:57+00:00 Damien George damien.p.george@gmail.com 2014-11-29T13:48:45+00:00 urn:sha1:29a1ec1bd6680d1108408cc825935012af10d938 This patch overhauls the network driver interface. A generic NIC must provide a set of C-level functions to implement low-level socket control (eg socket, bind, connect, send, recv). Doing this, the network and usocket modules can then use such a NIC to implement proper socket control at the Python level. This patch also updates the CC3K and WIZNET5K drivers to conform to the new interface, and fixes some bugs in the drivers. They now work reasonably well.
