[1932819331hy-debug]

Fixes #912.
Fixes #839: sqlite:///abs and sqlite://rel now reach sqlx unchanged, preserving its path semantics.

Root cause

SqliteConnector::connect reconstructed sqlite://{db_path} from ConnectionInfo, dropping all URI query parameters. This silently discarded security-sensitive mode=ro, mode=rw and mode=rwc, along with other sqlx-supported options.

Changes

• Pass an explicitly supplied sqlite: URI to sqlx unchanged, allowing its native parser to honor mode, cache, immutable and vfs (and preserving absolute vs relative URI path semantics).
• Preserve existing conversion of bare file paths and :memory: to SQLx connection strings.
• Environment credentials (DATABASE_URL, SQLITE_*) are no longer applied to SQLite connection strings.
• Add SQLite-feature integration regressions for mode=rwc creating a missing DB, mode=rw refusing to create a missing DB, and mode=ro denying a write.

Testing status — 2026-10-19 JST

Current tested head: f791a56b54193cd81042310fea3a28925243ae2c (the latest change explicitly enables environment credential loading in the isolated regression; no production logic change). GitHub-hosted runs on this head are all PASS:

• CI 39200004072: formatting/Code Quality, Rust core/features, SQLite database integration, Python 3.10–3.14 and wheel-smoke matrix.
• Security 39200003981: PASS.
• Benchmarks 39200003999: PASS.
• Bounded Fuzzing 39200004074: PASS (stable corpus on Ubuntu/Windows and four ASan jobs).

Earlier CI failed only at cargo fmt --all -- --check for sqlite_url_options.rs; commit 8c791b9 applies the exact formatter layout without changing runtime semantics. The PR is now Ready for Review. These are hosted CI outcomes, not a claim of local Rust-toolchain testing.

AI assistance disclosure: GPT-6 generated the patch and tests; the changes were independently inspected against the issue and upstream source. Maintainer validation remains necessary.

Summary by CodeRabbit

• Bug Fixes
  • SQLite connections now preserve URL options and path semantics. Create mode can create a missing database, read-write mode rejects missing databases, and read-only mode allows connections to existing databases while preventing writes.
  • SQLite connections retain their specified paths and options when environment credentials are enabled, and explicit SQLite URLs are used even when an unrelated PostgreSQL connection setting is present.

📝 Walkthrough

The SQLite connector now passes connection strings beginning with sqlite: unchanged to SQLx. Environment credentials are not applied to SQLite. Tests cover URL mode behavior and explicit SQLite URLs alongside an unrelated PostgreSQL DATABASE_URL.

Changes: SQLite connection handling

Layer / File(s)	Summary
Preserve SQLite connection settings crates/dataprof-db/src/connectors/sqlite.rs, crates/dataprof-db/src/lib.rs	The connector passes SQLite URLs through to SQLx and retains path-based construction for other connection strings. Credential application skips SQLite targets.
Verify SQLite URL behavior crates/dataprof-db/tests/sqlite_url_options.rs	Tests verify that mode=rwc creates a missing database, mode=rw rejects a missing database, and mode=ro rejects writes. A subprocess test checks an explicit SQLite URL when an unrelated PostgreSQL DATABASE_URL is set.

SQLite URIs now keep their query options, and unrelated PostgreSQL environment credentials no longer override them. No merge-blocking risk remains; a small optional test tweak is suggested.

Full details: Linked Issues check

Explanation

The implementation satisfies [#912]. SqliteConnector::connect passes explicit sqlite: URIs to SQLx without rebuilding them, so mode, cache, immutable, and vfs remain available. Bare paths and :memory: retain their conversion. The SQLite regression tests cover mode=rwc, mode=rw, and mode=ro behavior. The environment-credential guard prevents an unrelated DATABASE_URL from replacing an explicit SQLite target.

Full details: Out of Scope Changes check

Explanation

The changes stay within [#912]. The connector change, SQLite regression tests, and environment-credential guard all protect explicit SQLite URI behavior and its query options. No unrelated product behavior is demonstrated.

Make environment loading explicit in the child regression.

DatabaseConfig::default() currently enables environment loading, so create_connector reaches the SQLite guard. The test should set this field explicitly so a future default change cannot make the test pass without exercising that guard.

Suggested fix

     let mut connector = create_connector(DatabaseConfig {
         connection_string: sqlite_url(&path, "rwc"),
+        load_credentials_from_env: true,
         ..Default::default()
     })

Thanks, this fixes #912 and, by passing the URL through unchanged, #839 as well.

Checked locally on Windows, since CI runs the SQLite tests only on Linux: cargo test -p dataprof-db --features sqlite --test sqlite_url_options passes 5/5, so the sqlite:///C:/... form built by sqlite_url works there too. Reverting connectors/sqlite.rs alone fails three tests, and reverting lib.rs alone fails explicit_sqlite_mode_survives_unrelated_database_url, so both halves are guarded.

Two additions to the description before merge:

• Fixes #839: sqlite:///abs and sqlite://rel now reach sqlx with the meaning sqlx gives them.
• The behaviour change: environment credentials (DATABASE_URL, SQLITE_*) are no longer applied to a SQLite connection string.

The inline notes are non-blocking.

[AndreaBozzo]

Non-blocking: connect accepts any sqlite: prefix here, but create_connector in lib.rs still routes only sqlite:// to this connector, so sqlite::memory: (the form sqlx documents) is rejected as unsupported before it gets here. Matching the prefix there too would line the two up:

    } else if connection_str.starts_with("sqlite:")
        || connection_str.ends_with(".db")
        || connection_str.ends_with(".sqlite")
        || connection_str == ":memory:"

Fine as a follow-up.

[AndreaBozzo]

Non-blocking: with environment credentials skipped for SQLite, a URL that carries its own (sqlite://user:pw@host:1/x.db) now goes to sqlx as is, and sqlx reads user:pw@host:1/x.db as a file name. #897 adds a check in SqliteConnector::new that rejects credentials and ports on SQLite URLs; that can land separately.
