Consider using service dependencies instead of sleep
Based on the analysis of the codebase, I'm modifying my previous recommendation. The docker-compose.cicd.yaml shows that the agent service properly depends on carla-simulator and roscore services. Instead of using a complex retry mechanism, we should leverage Docker Compose's built-in dependency handling:
Add these service dependencies to ensure proper startup order:
depends_on:
- carla-simulator
- roscore
This approach:
Removes the arbitrary sleep 10 and relies on Docker's service orchestration
Maintains error handling for critical file operations
Improves readability and logging
Preserves the original functionality in a more robust way
🔗 Analysis chain
**Enhance command robustness and readability.**
The current command structure has several potential issues:
1. The `sleep 10` is a brittle way to handle timing dependencies
2. No error handling for critical operations (chmod, chown, mkdir)
3. Multiple sudo operations without checking for failures
Consider refactoring to this more robust approach:
```diff
command: |-
- bash -c "sleep 10 && sudo chown -R ${USER_UID}:${USER_GID} ../ && \
- sudo chmod -R a+w ../ && sudo mkdir -p $${XDG_RUNTIME_DIR} && sudo chmod 0700 $${XDG_RUNTIME_DIR} && sudo chown -R ${USER_UID}:${USER_GID} $${XDG_RUNTIME_DIR} && \
- (rqt_console &) && disown -a && \
- python3 /opt/leaderboard/leaderboard/leaderboard_evaluator.py --debug=0 --routes=$${ROUTE} --agent=/workspace/code/agent/src/agent/agent.py --host=$${CARLA_SIM_HOST} --track=MAP"
+ bash -c '
+ # Setup error handling
+ set -e
+
+ # Function to retry operations with timeout
+ wait_for_service() {
+ local retries=30
+ local wait_time=2
+ while [ $retries -gt 0 ]; do
+ if [ -d "../" ]; then
+ return 0
+ fi
+ retries=$((retries-1))
+ sleep $wait_time
+ done
+ return 1
+ }
+
+ # Wait for services to be ready
+ echo "Waiting for services..."
+ wait_for_service || { echo "Service startup timeout"; exit 1; }
+
+ # Setup permissions

+ sudo chown -R ${USER_UID}:${USER_GID} ../ || { echo "Failed to set ownership"; exit 1; }
+ sudo chmod -R a+w ../ || { echo "Failed to set permissions"; exit 1; }
+
+ # Setup runtime directory

+ sudo chown -R ${USER_UID}:${USER_GID} $${XDG_RUNTIME_DIR} || { echo "Failed to set runtime dir ownership"; exit 1; }
+
+ # Start rqt_console in background
+ echo "Starting rqt_console..."

+ --routes=$${ROUTE} \
+ --agent=/workspace/code/agent/src/agent/agent.py \
+ --host=$${CARLA_SIM_HOST} \

```
This refactored version:
- Replaces static sleep with dynamic service checking
- Adds proper error handling and logging
- Improves readability with structured sections
- Uses `exec` to replace shell with the Python process
Let's verify the service dependencies:
---
Let's search for any service dependencies and timing-related patterns in the build directory to better understand the startup requirements.
---
Let's examine the service dependencies and health check configurations to better understand the startup requirements and validate our recommendation.
