Summary
Adds a new environment variable
OPENCODE_DISABLE_FILETIME_CHECKthat allows users to skip the FileTime verification check before editing files.Problem
Currently, OpenCode enforces that files must be read before editing, tracked by timestamps. This causes issues:
Solution
Added
OPENCODE_DISABLE_FILETIME_CHECKflag that:true: Skips all FileTime checks, allowing edits without re-readingfalse: Maintains existing default behavior for safetyChanges
OPENCODE_DISABLE_FILETIME_CHECKconstant inpackages/opencode/src/flag/flag.tsFileTime.assert()inpackages/opencode/src/file/time.tsto check flagpackages/opencode/test/file/time-flag.test.tsTesting
All tests pass:
Usage
```bash
Temporary (single command)
OPENCODE_DISABLE_FILETIME_CHECK=true bun dev
Permanent (add to ~/.bashrc or ~/.zshrc)
export OPENCODE_DISABLE_FILETIME_CHECK=true
```
Trade-offs
This is a convenience vs safety trade-off:
Users who are confident in their workflow can enable this flag for better experience.
Closes #4406
