#callgraph — Public Fediverse posts

What happens during a #TYPO3 #v13 frontend call? #DDEV integrates the #PHP #Profiler #XHProf which visualizes the process as a #svg #callgraph. This will be useful for research in our #Translation Handling #Initiative. Are you able to follow the path? 🕸️😄 https://www.youtube.com/watch?v=HMInYFu1LqU

@joxean I think a fine-grained callgraph including call site information would break this tie.

Match the call sites in the two binaries, using instruction-level comparisons. You can then differentiate between the two call edges, based on which call site they are from.

I'm happy to share that I just released #MetaCG version 0.5.0 \o/

Besides a number of important bug fixes, we have *finally* reworked some internals that gave us a great performance improvement. For several use cases from minutes to seconds.
Thank you so much to everybody who contributed.

@ehmatthes you could roll your own with Python's ast module, I reckon.

Try :github: CodeQL for this (free for open source). It'd be pretty easy to get call graph nodes and edges and make a GraphViz diagram (or other graph):

Another option would be TreeSitter, again by :github:. There's a :rust: crate for making graphs from TreeSitter: https://github.com/tree-sitter/tree-sitter-graph

(I work at GitHub)

Joern also supports Python: https://docs.joern.io/cpgql/calls/
