perf: ripgrep config file search scans entire home directory including large hidden directories

[RovshanMuradov]

Summary When OpenCode starts, it runs a ripgrep search with the pattern **/opencode/config.* that recursively scans the entire home directory, including large hidden directories like ~/.local, ~/.cache, node_modules, etc. This causes extremely high CPU usage (1000%+) and can take 10+ minutes to complete. Environment

• OpenCode version: 1.0.223
• OS: Linux (also likely affects macOS)
• Shell: fish Steps to Reproduce

1. Have a home directory with large hidden folders (common on most systems):
   • ~/.local (can be 100+ GB)
   • ~/.cache (can be 10+ GB)
   • ~/.npm, ~/.cargo, ~/.rustup, etc.
2. Run opencode in any directory
3. Observe rg process consuming high CPU for extended periods Observed Behavior OpenCode spawns a ripgrep process with the following command: /usr/bin/rg --files --glob=!.git/* --follow --hidden --glob=**/opencode/config.* This command:

• Uses --hidden flag, which includes all hidden directories
• Uses --follow flag, which follows symlinks (potential for infinite loops)
• Searches recursively from the current or home directory
• Takes 9+ minutes and consumes 1000%+ CPU on systems with large hidden directories Activity monitor showing the issue:
• Process running for 9+ minutes at high CPU usage Expected Behavior Config file search should:

1. Only search in documented config locations (~/.config/opencode/, project root, $OPENCODE_CONFIG)
2. Exclude common large directories (.cache, .local, node_modules, etc.) by default
3. Complete within seconds, not minutes Workaround Creating a ~/.ignore file with the following content resolves the issue: .cache/ .local/ .npm/ .bun/ node_modules/ .cargo/ .rustup/ go/ .gradle/ .m2/ After adding this file, the search completes in ~0.01 seconds instead of 9+ minutes. Suggested Fix Consider one of these approaches:
4. Search only documented locations - Instead of recursive glob search, directly check:
   • ~/.config/opencode/opencode.json
   • ./opencode.json (project root)
   • $OPENCODE_CONFIG env var
5. Add default ignore patterns - Include common large directories in the search exclusion list
6. Limit search depth - Use --max-depth flag to prevent deep recursive searches
7. Remove --follow flag - Prevent potential infinite loops from symlinks Additional Context The glob pattern */opencode/config. also doesn't match the actual config filename opencode.json, which may indicate the search is looking for something else (plugins? legacy config names?). If this search is intentional, the ignore patterns should still be added to prevent scanning irrelevant directories.
