fix(backend): decode percent-encoded characters in generic git URL repo names by Tyagiquamar · Pull Request #1666 · sourcebot-dev/sourcebot

Tyagiquamar · 2026-09-17T17:06:44Z

Direct-URL generic git configs built the repo name from the raw percent-encoded pathname, while the file-based path already decodes it. This reuses the same decodeURIComponent approach so both paths produce consistent names and zoekt metadata.

Verified: added a regression test with a %20 URL. It fails on main (name keeps %20) and passes with this change. Backend vitest suite for repoCompileUtils (15 tests) and tsc build pass in Docker (node:24-bookworm).

Note

Low Risk
Narrow change to generic git URL repo naming with explicit handling for bad encodings; existing repos with literal %20 in names could rename on re-sync.

Overview
Fixes inconsistent repository naming for direct HTTP(S) generic git URLs by decoding percent-encoded path segments (e.g. %20 → spaces) before building name, displayName, and Zoekt gitConfig metadata—matching the existing file:// generic git compile path.

Malformed URL encoding is handled safely: a URIError from decodeURIComponent logs a warning, reports an INVALID_REPOSITORY_SOURCE discovery issue, and skips the URL instead of failing the whole compile.

Adds a regression test for a %20 clone URL and documents the fix in CHANGELOG.

Summary by cubic

Fixes #1384 by decoding percent-encoded characters (like %20) in repo names for direct-URL generic git configs, so they match the file-based path and zoekt metadata. Malformed encodings are now handled safely: the URL is skipped with an INVALID_REPOSITORY_SOURCE discovery issue instead of failing the whole compile.

Adds a regression test for a %20 URL that fails on main and passes with this change.
Adds a CHANGELOG entry.

Existing repos with literal %20 in their names could rename on re-sync.

^{Written for commit b4c6f86. Summary will update on new commits.}

Summary by CodeRabbit

Bug Fixes
- Repository names from direct generic Git URLs now correctly decode percent-encoded characters, such as spaces.
- Decoded names are consistently reflected in repository displays and Git metadata.
- Malformed percent-encoded URLs are now skipped with a clear repository source issue instead of causing processing failures.
Documentation
- Added an unreleased changelog entry documenting the URL decoding fix.

Walkthrough

The generic Git URL compiler now decodes percent-encoded repository path characters before creating repository names and metadata. Malformed encodings produce an invalid repository source issue. Tests and the changelog cover the fix.

Changes

Layer / File(s)	Summary
Decode repository path names `packages/backend/src/repoCompileUtils.ts`, `packages/backend/src/repoCompileUtils.test.ts`, `CHANGELOG.md`	The compiler decodes the URL pathname before stripping `.git` and building repository names. It reports malformed URI decoding as an invalid repository source. The test verifies decoded names and zoekt metadata. The changelog records the fix.
