An SRE at PingCAP here. Got it. Thanks! We found that using JS to toggle page visibility has some usability issues. We just removed the JS loading animation and will deliver content with good compatibility and progressive enhancement. Sorry for the issues with the display!

Thank you for the information, very helpful, I will learn and try it in our test.

Author here. Thanks for your great advice. We will apply this experimental project to testing TiDB in the future and output the report to https://github.com/fuzzdebugplatform/fuzz_debug_platform/iss.... Through the statistics of code block coverage, we can not only identify suspicious code blocks but also count code coverage.

The fuzzer we implemented is driven by BNF expressions. We can adjust the inputs of the fuzzer based on the statistics.

Author here. Functional languages indeed avoid many code defects from its own design, and it is also easier to locate the problematic code. That's why we originally chose Rust rather than C++ to develop the TiKV project in PingCAP.

It's hard to implement a bot to do auto-debugging. The purpose of this Hackathon project was to develop a tool to improve debugging efficiency. Check out our progress on https://github.com/fuzzdebugplatform/fuzz_debug_platform.
