Closes #409

Every test now gets a cache database of its own.

A CacheManager built without a db_path, and a conversion run without CLAUDE_CODE_LOG_CACHE_PATH, put the cache at <projects_dir>/claude-code-log-cache.db. A test whose project sits directly in the system temp dir (test_tui.py's temp_project_dir, among others) therefore shared <tmp>/claude-code-log-cache.db with every other such test, every run and every checkout on the machine. That broke in two ways:

• Stale schema. The file outlives the run and keeps the schema of the last code that opened it. A database migrated one step past this tree (a migration dropping a column the code reads) fails 38 tests on main: 24 in test_tui.py, 13 in test_pagination.py, 1 in test_template_rendering.py, all with sqlite3.OperationalError: no such column.
• Migration race. On a fresh temp dir, xdist workers run the migration chain on the same new file at once. test_tui.py -n auto failed 4–5 of its 63 tests per run with UNIQUE constraint failed: _schema_version.version, or with one DDL statement applied twice.

With this change both pass: 123 tests over the same stale database, which is left untouched, and 63 of 63 on each of three fresh temp dirs.

The fixture

An autouse fixture in test/conftest.py, _isolated_cache_path, sets CLAUDE_CODE_LOG_CACHE_PATH to a file in a fresh directory beside each test's tmp_path. The directory sits beside tmp_path rather than inside it, so tmp_path holds only what the test put there.

• Subprocesses and render workers inherit the variable.
• A test that sets the variable itself still wins.
• The fixture uses a MonkeyPatch of its own rather than requesting monkeypatch. An autouse fixture that requests it sets it up before the xunit setup_method fixture, which delays undoing the test's patches until after teardown_method has run.

Opting out: @pytest.mark.default_cache_path

A test that relies on the default location takes this new marker (registered in pyproject.toml). The marker unsets the variable. Every test that carries it keeps its project in a subdirectory of a private temp dir, so the shared file does not come back.

• Tests that assert where the database lands:
  • test_cache.py: test_initialization, test_database_path, test_default_path_without_env_var.
  • test_integration_realistic.py: test_clear_cache_with_projects_dir, test_cache_creation_all_projects.
  • test_codex_walker.py: the four tests that check whether the database is under the output root. The two that assert it is absent would pass vacuously with the cache moved elsewhere.
• Tests that compare two projects' cache rows: test_entry_store.py's TestAppendOnlyWrites, and test_incremental_cache_refresh.py's TestIncrementalEquivalence and TestIncrementalDeclines. Their helpers read every row of the database they open. With one shared database, both sides read both projects' rows: two tests failed, and the rest passed by comparing the rows with themselves.
• A module-scoped fixture whose cache a test looks up again: test_minimal_pages_browser.py, whose module-scoped archive is built before the per-test fixture runs. The module takes the marker, so the archive and each test's search server resolve the same file.

Tests that resolve several project dirs to the one per-test database are otherwise left as they are. They compare rendered output, and every cache table is keyed by project or by file, so several projects in one database is what a real archive is.

test/test_cache_isolation.py pins the fixture and the marker:

• a project made with tempfile.TemporaryDirectory() gets a per-test path,
• a subprocess resolves the same path,
• the marker restores the default.

just test, just test-tui and just test-browser pass, and none of them leaves a claude-code-log-cache.db in the temp dir.

Summary by CodeRabbit

• Tests
  • Improved test isolation by assigning temporary cache locations by default, while preserving default cache-path behavior in tests that explicitly check it.
  • Added coverage for cache-path isolation, including subprocess and browser scenarios.

Walkthrough

The test suite now assigns an isolated cache path to each test by default. Tests marked default_cache_path instead run with the cache-path environment variable unset. New tests check isolation and default-path resolution.

Changes: Test cache path isolation

Layer / File(s)	Summary
Cache-path fixture and marker pyproject.toml, test/conftest.py	The autouse fixture sets a per-test cache path unless a test uses the default_cache_path marker. Marked tests run with the cache-path environment variable unset.
Cache-path isolation tests test/test_cache_isolation.py	Tests verify that temporary projects use a cache path distinct from the shared path, and that the default path is used when the environment variable is absent.
Default-path test coverage test/test_cache.py, test/test_codex_walker.py, test/test_entry_store.py, test/test_incremental_cache_refresh.py, test/test_integration_realistic.py, test/test_minimal_pages_browser.py	Existing tests that check default-path behavior or compare cache state across projects are marked to use the default cache path.

Browser search tests can fail when a cache path is already configured. Unsetting the override is a workaround.

Full details: Title check

Explanation

The title "(Claude) Give every test a cache database of its own" matches the main change. The PR adds an autouse fixture that gives each test its own cache database in a fresh directory beside tmp_path, which addresses linked issue #409 about the shared <tmp>/claude-code-log-cache.db. The title is concise and specific. The "(Claude)" prefix is a minor style note and does not affect the assessment.

Full details: Linked Issues check

Explanation

[#409] requires that tests stop sharing <tmp>/claude-code-log-cache.db. The issue proposes, as one option, an autouse fixture that sets CLAUDE_CODE_LOG_CACHE_PATH to a per-test path for every test that does not set its own. The reviewed head implements this option. test/conftest.py adds the autouse fixture _isolated_cache_path. Unless the test has the default_cache_path marker, it sets the variable to claude-code-log-cache.db in a fresh directory made by tmp_path_factory.mktemp("cache"). Because the fixture applies to all tests, it covers the verified files (test_tui.py, test_pagination.py, test_template_rendering.py) and the unchecked files listed in the issue. The variable reaches subprocesses and render workers through the environment. The default_cache_path marker is registered in pyproject.toml. It unsets the variable only for tests that check the default location. Those tests keep their projects in per-test directories, so they do not reuse the shared file. The issue asks for no coding work beyond this isolation. The author's test results (just test, just test-tui, just test-browser, the stale-database run, and the fresh-temp-dir runs) were not reproduced in this review. The PASS rests on the code at the reviewed head.

Full details: Out of Scope Changes check

Explanation

Every changed file supports the cache-isolation objective of [#409]. test/conftest.py adds the autouse fixture. pyproject.toml registers the default_cache_path marker that the fixture reads. test/test_cache_isolation.py adds tests for the fixture and the marker. The marker is added to tests that assert the default database location (test_cache.py, test_integration_realistic.py, four tests in test_codex_walker.py). It is also added to tests that compare cache rows of two projects (test_entry_store.py, test_incremental_cache_refresh.py), and to the module-scoped browser fixture in test_minimal_pages_browser.py. Without the marker, the isolation change would break these tests or make them pass without checking anything, so each addition is needed. The changes add no unrelated behavior, refactor no production code, and leave the assertions of the marked tests unchanged. No out-of-scope change was found.

Check cache paths across tests.

Add a check that compares cache paths from separate fixture invocations. The current isolation tests can pass if every unmarked test uses the same file under pytest’s base temp directory.

Clear the cache override before building the archive.

If the invoking environment sets CLAUDE_CODE_LOG_CACHE_PATH, archive indexes that path, but server opens the default path. Search tests can then fail because the default database does not exist.
