In most cases it is not necessary to do these checks because it is guaranteed that the input object has the stream protocol and desired C methods. For example, native objects that use the stream wrappers (eg mp_stream_readinto_obj) in their locals dict always have the stream protocol (or else they shouldn't have these wrappers in their locals dict). This patch introduces an efficient mp_get_stream() which doesn't do any checks and just extracts the stream protocol struct. This should be used in all cases where the argument object is known to be a stream. The existing mp_get_stream_raise() should be used primarily to verify that an object does have the correct stream protocol methods. All uses of mp_get_stream_raise() in py/stream.c have been converted to use mp_get_stream() because the argument is guaranteed to be a proper stream object. This patch improves efficiency of stream operations and reduces code size. 2018-05-01T05:54:50+00:00 Ayke van Laethem aykevanlaethem@gmail.com 2018-04-24T15:43:14+00:00 urn:sha1:d43c7377564b3e1be36f627a465df2c5779a1ae8 This is a more consistent use of errno codes. For example, it may be that a stream returns MP_EAGAIN but the mp_is_nonblocking_error() macro doesn't catch this value because it checks for EAGAIN instead (which may have a different value than MP_EAGAIN when MICROPY_USE_INTERNAL_ERRNO is enabled). 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. 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.
