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

Medium Risk
Changes canonical repo identity for direct generic git URLs on re-sync, which can affect indexing, search filters, and Zoekt shard naming for affected deployments.

Overview
Fixes inconsistent repository naming for direct HTTP(S) generic git connection URLs by decoding percent-encoded path segments (e.g. %20 → spaces) when building name, displayName, and Zoekt gitConfig metadata—matching behavior the file-based generic git path already had.

Malformed percent-encoding in a URL now skips that target and records an INVALID_REPOSITORY_SOURCE discovery issue instead of failing compilation. A regression test covers spaced repo names in URLs, and the changelog is updated.

Note: Repos that were previously registered with literal %20 in the name may appear under a new name after the next connection sync.

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 URL encodings now skip the URL with an INVALID_REPOSITORY_SOURCE discovery issue instead of failing the whole compile.

Adds a regression test for a %20 URL.
Adds a CHANGELOG entry.

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

^{Written for commit 88aec56. 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, and display the decoded names consistently in repository details and Git metadata.
- URLs with malformed percent-encoding are skipped and reported as invalid repository sources, rather than interrupting repository processing.

Walkthrough

The generic Git URL compiler decodes percent-encoded repository paths before building repository names and metadata. If decoding fails with a URIError, it reports an invalid repository source and returns no repositories. Tests and the changelog cover the change.

Changes

Generic Git URL names

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. If decoding throws a `URIError`, it logs a warning, reports an invalid repository source, and returns no repositories. The test verifies decoded names and zoekt metadata. The changelog records the fix.
