Thread Sanitizer data race issues. #240

Closed JCash closed 1 year ago

JCash commented 1 year ago

I wanted to create a small threaded test to run it through Clang's thread sanitizer, and it seems to produce a lot of output. I'm not sure how many are false positives, but I think it would be great if we could fix them somehow, since I hope more ppl will use the thread sanitizer (and other tools) on their projects in the future.

I have a branch draft here: https://github.com/Celtoys/Remotery/pull/239

I hope I have setup the test correctly. Currently only tested on macOS, but using pthreads, it should work on linux too.

Compile & run with:

clang -std=c89 -DRMT_ENABLED=1 -g -O0 -fsanitize=thread -Ilib sample/thread.c lib/Remotery.c -o build/test && ./build/test

Here's the output for the online readers:
