I just threw together a script for easily attaching a debugger to any of your [overmind](/tags/overmind) run processes. let me know if it's useful!
|
|
|
|
I'm using it for attaching to my [rails](/tags/rails) processes, as I don't like how `overmind connect web` echoes _everything_ the web process outputs.
|
|
|
|
```sh bin/debug
|
|
#!/usr/bin/env sh
|
|
|
|
if [[ "$1" == "--help" ]]; then
|
|
echo "Usage: $0 [web/worker/etc…]"
|
|
echo
|
|
echo "Attach an rdbg debugger to the named overmind process. (default: web)"
|
|
exit 0
|
|
fi
|
|
|
|
PROCESS=${1:-web}
|
|
PROCESS_PID=$(overmind ps | grep -E "^${PROCESS}" | tr -s ' ' | cut -d' ' -f2)
|
|
[[ -z $PROCESS_PID ]] && { echo "There is no running overmind process called '$PROCESS'" >&2; exit 1; }
|
|
DEBUGGER_PID=$(pgrep -P $PROCESS_PID)
|
|
[[ -z $DEBUGGER_PID ]] && { echo "The $PROCESS process doesn't seem to have any child processes" >&2; exit 1; }
|
|
|
|
bundle exec rdbg -An "rdbg-$DEBUGGER_PID"
|
|
```
