gdb-pounce
Wait until a process with a certain name starts and attach to it with gdb. While for many use cases
while ! pidof "$NAME"; do :; done; gdb -p "$(pidof "$NAME")"is sufficient, gdb-pounce will stop right at the loader entry point, as if the process was started under gdb in the first place.
Usage
python3 -m pip install --upgrade --user gdb-pounce
sudo env "PATH=$PATH" gdb-pounce [GDB OPTION]... [NAME]When is this useful?
When an interesting process (usually a part of some complex software) starts in a non-trivial environment, for example:
As a specific user.
In a specific namespace.
With additional environment variables.
With additional file descriptors.
While another process is in a specific state.
and we need to debug its initialization.
Prerequisites
bcc >= 0.15.0
linux kernel >= 5.3 (>= 5.5 for the container support)
nsenter (for the container support, optional)
python3 >= 3.7
pounce?
gdb-pounce lies in wait for its victim process. The very moment the process appears, gdb-pounce pounces at it and seizes it, leaving it no chance to react.
