openmano-mpy/lib/embed, branch master MicroPython source and hardware configuration for OpenMano py/stream: Remove mp_stream_errno and use system errno instead. 2020-04-27T13:58:46+00:00 Damien George 2020-04-20T13:48:34+00:00 e08ca78f40bb1948acffa60c0315083acfb02227 This change is made for two reasons: 1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system provided errno for certain errors, and yet MicroPython stream objects that it calls will be using the internal mp_stream_errno. So if the library returns an error it is not known whether the corresponding errno code is stored in the system errno or mp_stream_errno. Using the system errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this ambiguity. 2. For systems that have threading the system-provided errno should always be used because the errno value is thread-local. For systems that do not have an errno, the new lib/embed/__errno.c file is provided.

Helpful when porting existing C libraries to MicroPython. abort()ing in
embedded environment isn't a good idea, so when compiling such library,
-Dabort=abort_ option can be given to redirect standard abort() to this
"safe" version.
