Error message
数据库已提交，前端文件发布失败: %w
What it means
This error wraps a failure that occurred while publishing the frontend file batch of an auto-generated code task, raised AFTER the database transaction has already been committed. commitAutoCodeFileTask applies backend files first, persists to the DB, then applies frontend files; if the frontend publish fails the DB write cannot be undone, so the error is annotated to make that irreversible state explicit while the already-applied frontend files are rolled back to their pre-task content.

Solutions
- Check the wrapped cause: if it is '自动代码目标文件已被外部修改', restore or manually reconcile the externally changed target, then re-run the code generation task
- Verify the web/ root and target directories are writable by the server process (permissions/ownership)
- Ensure no process is holding locks on target files (editors, file watchers) during generation
- Note the DB row is already committed: inspect the generated record and re-run only the file-publish phase or manually create the frontend files if rollback also failed
Example fix
// before: fixing by manually editing generated files then retrying blindly $ vim web/src/view/.../xxx.vue # target drifted -> conflict on retry // after: revert external edits so hash matches prepared BeforeHash, then re-run $ git checkout -- web/src/view/.../xxx.vue # re-trigger auto-code commit; frontend publish now succeeds

} Prevention
- Do not hand-edit generated files while a generation task is pending; change the templates instead
- Run the server process with write access to the whole project root (server/ and web/)
- Avoid git pull/stash/checkout and file watchers rewriting targets during generation
- Treat this error as a partial-failure signal: the DB write succeeded even though files may be rolled back
When it happens
Trigger: Calling the auto-code commit flow (commitAutoCodeFileTask with publishPreparedAutoCodeFile) when any frontend target file publish fails: the target was externally modified since preparation (errAutoCodeFileConflict), creating the target directory failed, the atomic rename failed, or hashing the target failed.
Common situations: A developer or editor touched a generated web/ file between task preparation and commit; the frontend root directory is read-only or owned by another user; a target path became a directory or was deleted; cross-device rename issues (staging dir and target on different filesystems).
