I wrote an update about breaking the rev lock between LLDB & Python: https://jonasdevlieghere.com/post/breaking-lldb-python-revlock/
Breaking the LLDB/Python Revlock

Since its inception, scripting has been an integral part of LLDB. At the time, Python was chosen as the primary, and for a long time the only supported, scripting language. Python is used within LLDB to automate things, write custom data formatters, and extend core concepts like Processes and Threads with an implementation written in Python.

Read about the work and its implications at our blog: https://ostif.org/bolt-security-engagement-complete/

Huge thank you to Kristof Beyls, creator of the BOLT binary scanner.

LLVM Community Testimonial on Open Access

Clang was initially released in 2007, is freely available, and is one of the most widely deployed compilers for C and C++ in the w...

"Contributing to an open source project is an iterated game and the majority of the value that a contributor can bring to a project lies in the later iterations. In other words, you initially invest some energy (i.e. place a bet) to onboard a new contributor, and you hope that later on that relationship starts paying you back as the contributor becomes more trusted and prolific."
