build: load exporter assets from encoded filesystem paths by minwookshin · Pull Request #3110 · TypeCellOS/BlockNote

minwookshin · 2026-09-23T00:59:58Z

Summary

Vite asset imports percent-encode filesystem paths. loadFileBuffer passes those URLs directly to readFileSync, causing exporter tests to fail with ENOENT when a checkout path contains spaces or non-ASCII characters.

Rationale and changes

Decode the imported asset path once before the existing /@fs and Windows-drive normalization. Add real-file regressions for absolute and /@fs paths containing spaces, Unicode, #, % and a literal %20, plus plain-path and font-data-URL checks.

Impact

This two-file repair affects shared test asset loading. Browser/data-URL behavior, editor behavior, dependencies and snapshots are unchanged. It is independent of the keyboard block-actions example.

Testing

On e5e30798e4a74b55ed7c5158762027b5f30108a2:

New regressions: five failures and one pass before → six passes after.
Existing ODT export suite: two failures and one pass before → three passes after.
Shared declarations rebuild; formatting and whole-tree type-aware lint pass.
All 15 native unit tasks pass with caches disabled: 2,146 tests, 286 existing skips. This broad run used the combined checkout, including the separate example; the example source does not change exporter asset loading.

The full existing browser/exporter matrix was not run. The optional local mkcert CA warning remains; these runs do not establish live TLS/model behavior.

Checklist

Regression tests added and verified red/green.
Formatting and whole-tree lint pass.
Complete existing browser/exporter matrix run.
No user-facing documentation update needed for this test helper repair.

AI-assisted implementation and validation with OpenAI Codex.

Summary by CodeRabbit

Bug Fixes
- Fixed test-mode file loading so existing filesystem paths containing percent signs are handled correctly, while encoded Vite asset paths are decoded when needed.
Tests
- Added coverage for plain and encoded file paths, binary file contents, and font data URL formatting.

Walkthrough

In test mode, loadFileBuffer checks for an existing filesystem path before decoding. It decodes Vite asset URLs when needed and keeps the original path if decoding fails. Tests cover encoded and direct paths, binary reads, and font data URLs.

Changes: Asset path loading

Layer / File(s)	Summary
Load and test asset paths `shared/util/fileUtil.ts`, `tests/src/unit/shared/fileUtil.test.ts`	`loadFileBuffer` preserves existing filesystem paths, decodes `/@fs/` URLs, and decodes other URLs when the original path does not exist. Tests cover encoded and unencoded paths, paths containing percent characters, binary reads, and `loadFontDataUrl`.

Priority: Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: Minimal · up to c611d

Existing and encoded asset paths retain the intended loading behavior. The test gap is narrow and does not block merging.

In `@shared/util/fileUtil.ts`:
- Line 36: Update loadFileBuffer to identify and preserve direct filesystem
paths before applying decodeURIComponent, while continuing to decode both
supported Vite asset URL forms, including encoded absolute paths without /@fs/.
Ensure raw paths containing %20 or %foo reach fs.readFileSync unchanged and do
not trigger URIError, and add regressions covering both cases.

The build and zizmor runs expired before approval; no jobs ran. Could a maintainer rerun and approve these checks?

Why do we need tests for this? that doesn't really make sense
