Hot patching

The README mentions hot patch support. Is there anywhere I can read more about this?

Support returning errors from query API

1

The query API is iterator based. Each iteration is technically fallible but there's no great way to report errors. I played around with making the iterator type by `Result` but...

Copying child process output

1

pexpect has `child.logfile*` APIs to log child process output to a file-like destination. I looked around the docs but I didn't seem to find anything similar for `rexpect`. Is there...

We have remote viewing implemented internally at FB. Laziness and dependency issues have kept it closed source. If there's any interest/desire from other folks to have it open sourced I...

dmesg stack trace does not match `prog.crashed_thread().stack_trace()`

Allow pinning entire object files at once instead of on a per-map or per-prog basis. Also make it work for bpf2go users. See individual commits for motivation and details.

These help with maintaining some uniformity in code. I think the codebase is already pretty good about these rules, so it's just codifying it. ##### Checklist - [ ] Language...

Variables declared inside loop does not respect lexical scope

Set up clang-tidy in CI

2

`clang-tidy` seems like a useful linter. C++ could really use all the linters it can get. https://github.com/marketplace/actions/clang-tidy-review looks useful but it might be nice to be able to run clang-tidy...

Audit all runtime tests that use regex for output parsing

We've noticed quite a few runtime tests that use regex to validate output are overly permissive in accepted input or are flat out wrong. For example `other.positional lhist` is probably...
