Debug with GDB on macOS 11

The big reason to do this is that LLDB has no ability to "follow-fork-mode child", in other words, a multi-process target that doesn't have a single-process mode (or, a bug that only manifests when in multi-process mode) is going to be difficult or impossible to debug, especially if you have to run the target over and over in order to make the bug manifest. If you have a repeatable bug, no big deal, break on the fork from the parent process and attach to the child in a second lldb instance. Otherwise, read on.

Install GDB

Don't make the mistake of thinking you can just brew install gdb. Currently this is version 10.2 and it's mostly broken, with at least two annoying bugs as of April 29th 2021, but the big one is https://sourceware.org/bugzilla/show_bug.cgi?id=24069

# Update GDB's Python paths with the `sys.path` values of the local Python installation,
#  whether that is brew'ed Python, a virtualenv, or another system python.

# Convert GDB to interpret in Python
python
import os,subprocess,sys
# Execute a Python using the user's shell and pull out the sys.path (for site-packages)
paths = subprocess.check_output('python -c "import os,sys;print(os.linesep.join(sys.path).strip())"',shell=True).decode("utf-8").split()

Workbench

We extract our test repos from this small Zip file.

• main is a "container" repository with its working copy,
• plugin is a "shared" repository with its working copy,
• remotes emulates remote bare repos for both, to better resemble regular usage.

The idea is to use plugin as a subtree of main in a vendor/plugins/demo path, and allow maintenance both ways:
