It consists of: 1. "do_handhake" param (default True) to wrap_socket(). If it's False, handshake won't be performed by wrap_socket(), as it would be done in blocking way normally. Instead, SSL socket can be set to non-blocking mode, and handshake would be performed before the first read/write request (by just returning EAGAIN to these requests, while instead reading/writing/ processing handshake over the connection). Unfortunately, axTLS doesn't really support non-blocking handshake correctly. So, while framework for this is implemented on MicroPython's module side, in case of axTLS, it won't work reliably. 2. Implementation of .setblocking() method. It must be called on SSL socket for blocking vs non-blocking operation to be handled correctly (for example, it's not enough to wrap non-blocking socket with wrap_socket() call - resulting SSL socket won't be itself non-blocking). Note that .setblocking() propagates call to the underlying socket object, as expected.
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Tests of capabilities not supported on all platforms should be written to check for the capability being present. If it is not, the test should merely output 'SKIP' followed by the line terminator, and call sys.exit() to raise SystemExit, instead of attempting to test the missing capability. The testing framework (run-tests in this directory, test_main.c in qemu_arm) recognizes this as a skipped test. There are a few features for which this mechanism cannot be used to condition a test. The run-tests script uses small scripts in the feature_check directory to check whether each such feature is present, and skips the relevant tests if not. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
