* Do not call `import socket` on each send()/recv() when using rustls Use method references cached during socket creation. * Implement reading of at most one TLS record from socket Previous algorithm didn't take into account that recv() may return less data than requested even for blocking sockets. * Remove special handling of rustls "buffer full" errors First of all, existing code does not really work and this leads to an infinite loop: https://github.com/RustPython/RustPython/issues/7891 Second, this should never happen when rustls used properly (wrt wants_read() and wants_write()) and thus all such errors are implementation bugs that must be properly fixed. * Replace own TlsConnection with rustls::Connection * Fix waiting on a socket 1) Ensure that socket_wait() called from TLS glue code allows threads 2) Ensure that socket_wait() called from TLS glue code properly handles EINTR on *nix 3) Ensure that select() or poll() error conditions are checked 4) Use poll() on *nix so socket descriptor values are not limited * Remove dead code from rustls glue * Do not present rustls errors as OSError(0, "Success") * Remove infinite loop "detection" from rustls glue TLS handshake cannot be infinite. Any infinite loop here is a serious bug in implementation and should be fixed properly. This code triggers in some cases (very short reads) with misleading `ssl_error.SSLWantReadError: The operation did not complete (read)`. * Add test for 1-byte max recv in TLS client * Add regression test for https://github.com/RustPython/RustPython/issues/7891 * Fix constants in rustls glue code * Deduplicate verify flags / record-size constants * Larger "max encrypted TLS record length"
Test snippets
This directory contains two sets of test snippets which can be run in Python.
The snippets/ directory contains functional tests, and the benchmarks/
directory contains snippets for use in benchmarking RustPython's performance.
Setup
Our testing depends on pytest, which you can install using pip.
Running
Simply run pytest -v in this directory, and the tests should run (and hopefully
pass). If it hangs for a long time, that's because it's building RustPython in
release mode, which should take less time than it would to run every test
snippet with RustPython compiled in debug mode.
