v1.17.x regression: 'fff scan timed out' crashes app in home directory #31682
Description
Bug Description
Running opencode in the home directory (~) crashes with Unexpected server error on v1.17.0 and v1.17.1. The same scenario works fine on v1.16.2.
Steps to Reproduce
- Install opencode v1.17.1
cd ~- Run
opencode
Expected Behavior
opencode should start normally (or gracefully handle the large directory), as it did in v1.16.2.
Actual Behavior
Crashes immediately with:
Error: Unexpected server error. Check server logs for details.
at <anonymous> (/$bunfs/root/chunk-j3wpssn9.js:8:7615)
at processTicksAndRejections (native:7:39)
Server log shows:
level=ERROR message=failed ref=err_846e2c9b error="fff scan timed out" cause="Error: fff scan timed out\n at KU (/$bunfs/root/chunk-kxc6dk47.js:12:2852)"
Regression Confirmation
| Version | Result |
|---|---|
| 1.16.2 | ✅ Works — TUI launches normally in home directory |
| 1.17.1 | ❌ Crashes — fff scan timed out |
Environment
- OS: macOS (Darwin 25.3.0, arm64)
- opencode version: 1.17.1 (regression), 1.16.2 (working)
- Home directory size: ~28,000 files within 4 levels depth, 122 top-level directories
Suggestion
The fff scan timeout should be handled gracefully — either by extending the timeout for large directories, skipping the scan with a warning, or falling back to lazy indexing. A scan timeout should not crash the entire application.

Worth noting:
I use opencode under WSL, repo is in mounted file system.

Additional confirmation from another macOS arm64 setup:
1.17.1crashes from$HOMEwith the sameUnexpected server error/fff scan timed outpath.--pureand with all external TUI plugins disabled, so it is not caused by user TUI plugins.opencode upgrade 1.17.0made the same$HOMEstartup stable again. That differs slightly from the original report's version table, but may help narrow affected builds/configs.Thanks for already fixing this in the upcoming release.
