Summary

This PR extends the contribution from SIV HARI NAIR (@sivharinair2001) (_thank you! 🙏), cherry-picked from #1071 so the original commit authorship is preserved. Requested by Aaron ("AJ") Steers (@aaronsteers).

Closes #290.

❓ What it does

VenvExecutor assumed the installed executable is named after the connector — _get_connector_path() returned <venv>/bin/<self.name>. When a connector package registers a differently-named console_scripts entry point, that path never exists, so ensure_installation() concluded the install was broken and reinstalled — every time, and then still failed.

It now asks the installed distribution what it actually put on PATH:

# executed by the venv's own interpreter, so we read *its* metadata
[ep.name for ep in metadata.entry_points(group="console_scripts")
 if ep.dist is not None and canonicalize(ep.dist.name) == canonicalize(package_name)]

and resolves the connector path from that name.

❗ Feature or RCA Impact

The root cause is the name assumption, not the installation: pip/uv were installing the connector correctly and PyAirbyte was looking for a file that was never going to exist. Two user-visible consequences go away:

  1. The reinstall loop — a healthy connector reinstalled on every ensure_installation() call, because the missing-executable check could never be satisfied.
  2. The misleading failure — the error claimed the executable could not be found in the virtual environment when it was there under its registered name.

Connectors whose script name already matches are unaffected: resolution checks <bin>/<connector-name> first and returns early, so the common path never spawns a subprocess.

📋 Enumerated changes

  1. _discover_console_script_names() — runs a generated script under the venv's interpreter and returns the sorted console_scripts entry-point names belonging to the connector's distribution.
  2. _resolve_console_script_name() — resolution order is valid cache → <bin>/<connector-name> → discovery, and it resolves from discovery only when an entry point matches the connector name or exactly one candidate exists.
  3. Distribution names are compared PEP 503-canonicalized (lowercased, runs of -/_/. collapsed to -), so Airbyte_Source.Foo matches airbyte-source-foo instead of silently falling through to the reinstall path.
  4. Interpolated values in both generated -c scripts use !r, including the pre-existing version lookup, so a package name can never break out of its string literal.
  5. The cached script name is revalidated against the filesystem before reuse and cleared on install() and uninstall(), so a cache outliving its executable can't make ensure_installation() accept a broken venv.
  6. ensure_installation() keys off _resolve_console_script_name() rather than a hardcoded path, and both failure paths carry discovered_console_scripts so an unresolvable case reports what the package did register.
  7. _get_pypi_package_name() replaces the package-name expression that was inline in get_installed_version().
  8. Coverage: three fixture packages (matching, canonicalization variant, two helper scripts) plus tests/integration_tests/test_console_script_discovery.py, asserting discovery, the normalization case, cache invalidation after the executable is deleted, and that the ambiguous case resolves to nothing.

🙋 Maintainer Decisions

  1. Ambiguity fails instead of guessing. With two or more candidates and none matching the connector name, resolution returns None and the existing installation error surfaces. The contributor's version picked entry_points[0], but nothing makes the first entry point the connector CLI, so that could launch an unrelated helper command instead of failing loudly.
  2. Discovery runs in the venv's interpreter, not ours. The connector's metadata only exists there, which is why this is a generated script rather than an in-process importlib.metadata call.
  3. The reinstall diagnostic names the bin directory, not a resolved path. That branch is reached precisely when resolution failed, so there is no resolved path worth printing.
  4. Tests are integration, not unit. They perform a real uv install of a local fixture package; the behavior can't be exercised without one.
  5. The contributor's commit is untouched. Maintainer cleanup is in separate follow-up commits on top, so the diff still shows who wrote what.

✔️ Repro of Issue, Proof of Fix?

Reproduced on unfixed main (f65f227) and confirmed fixed on this branch (c1b8c0b), using the same procedure both times: install the source-wrong-exe fixture (a package whose console_scripts entry point is wrong-script-name), then call ensure_installation().

Unfixed main — symptom present. Install succeeds, the executable is right there in bin/, and PyAirbyte still reinstalls and then fails:

INSTALL: ok
BIN CONTENTS: [..., 'python3.10', 'wrong-script-name']
Connector executable not found within the virtual environment at
.../.venv-source-wrong-exe/bin/source-wrong-exe.
Reinstalling...
Connector 'source-wrong-exe' installed successfully!
ENSURE_INSTALLATION: FAILED -> AirbyteConnectorInstallationError
    Connector Name: 'source-wrong-exe'
    Connector Path: PosixPath('.../.venv-source-wrong-exe/bin/source-wrong-exe')

That is issue #290 exactly, and it is the name assumption rather than a broken install: wrong-script-name is present and the reinstall changes nothing.

This branch — symptom gone. Same fixture, no reinstall, and the resolved executable answers the protocol:

INSTALL: ok
BIN CONTENTS: [..., 'python3.10', 'wrong-script-name']
ENSURE_INSTALLATION: ok
RESOLVED EXECUTABLE: wrong-script-name
CONNECTOR SPEC CALL: {"type": "SPEC", "spec": {"documentationUrl": ...

The regression test carries the same weight: restoring airbyte/_executors/python.py from main and re-running tests/integration_tests/test_console_script_discovery.py fails with FileNotFoundError: .../bin/source-wrong-exe, so it is the fix that the test is detecting rather than the fixture.

Test Plan

poetry run pytest tests/integration_tests/test_console_script_discovery.py
poetry run pytest tests/unit_tests
poetry run ruff format --check . && poetry run ruff check . && poetry run mypy .

Link to Devin session: https://app.devin.ai/sessions/6889407feb0c4b01be88b94eda0c468e

VenvExecutor no longer assumes the installed CLI name matches the connector
name. When they differ, resolve the executable via console_scripts metadata
instead of triggering a useless reinstall loop.

Closes #290

🟡 Connector executable lookup still fails when the installed package name is written differently

The installed program list is filtered by an exact text match on the package name (ep.dist.name == package_name at airbyte/_executors/python.py:100), so a package whose recorded name differs only in casing or dashes/underscores is skipped and no executable is found.
Impact: Some connectors still fail to launch with "executable could not be found" and get reinstalled repeatedly, exactly the situation this change is meant to remove.

Name-normalization mismatch in the entry-point discovery script

_get_pypi_package_name() (airbyte/_executors/python.py:80-83) returns either the registry's pypi_package_name or the synthesized airbyte-{name}. The discovery snippet compares this string verbatim against ep.dist.name, which is the Name field written into the installed dist-info and can legitimately be Airbyte_Source_Foo, airbyte_source_foo, etc. Per PEP 503/PEP 426 these are the same project, but the equality check treats them as different, entry_points ends up empty, the script prints "", _discover_console_script_name() returns None, and _resolve_console_script_name() returns None. ensure_installation() then takes the uninstall/reinstall branch (airbyte/_executors/python.py:346-365) and afterwards raises AirbyteConnectorInstallationError (airbyte/_executors/python.py:369-377). Comparing canonicalized names (lowercase, [-_.]+ collapsed to -) on both sides would make discovery robust. The same snippet also silently picks entry_points[0] when a dist ships several console scripts, which can select an unrelated helper command.

Suggested change
entry_points = [
ep
for ep in metadata.entry_points(group="console_scripts")
if ep.dist.name == package_name
]
if connector_name in {{ep.name for ep in entry_points}}:
print(connector_name)

else:

☑️ Resolved in 4038186. Good catch — this was a real compatibility hole, not a style point.

ep.dist.name comes back as the distribution's own metadata name, so a package published as Airbyte_Source.Foo never matched a pypi_package_name of airbyte-source-foo, and the entry-point list came out empty. Empty list meant "nothing discovered", which dropped straight back into the reinstall path — silently, and on every call.

Both sides are now compared PEP 503-canonicalized (lowercased, runs of -/_/. collapsed to -), inside the generated discovery script so the comparison happens where the metadata is read. tests/integration_tests/test_console_script_discovery.py covers it with a fixture whose distribution name is a canonicalization variant.

VenvExecutor now discovers installed console-script names from package metadata, caches and resets the result across lifecycle operations, and validates the resolved executable. Integration fixtures and tests cover mismatched, normalized, missing, and ambiguous script names.

Fixtures define mismatched, normalized, and ambiguous console scripts. Integration tests verify discovery and rejection behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to acf3a

The change correctly resolves mismatched console-script names, but some installation errors still omit the scripts that were discovered when automatic repair is disabled, making configuration failures harder to diagnose. The PR is mergeable with explicit owner awareness or a small follow-up to include that diagnostic context.

- Around line 97-109: Update the entry-point resolution logic in the

selecting entry_points[0]. Resolve automatically only when connector_name
matches an entry point or exactly one candidate exists; otherwise preserve the
full discovered-name list for _cli and its error context.
- Around line 358-360: Update the diagnostic print in the executable-not-found
handling to use self._get_connector_path() instead of constructing the path from
get_bin_dir(self._get_venv_path()) and self.name, so the reported path includes
the platform-specific executable suffix.
- Around line 124-131: The cached _console_script_name must be validated before
it is returned. Update the console-script resolution logic to verify the cached
executable path still exists, clear the cache when it is missing, and continue
resolving the default path so ensure_installation() cannot accept a stale cache.

In `@scripts/reproduce_issue_290.py`:
- Around line 1-22: The reproduction script’s module-level lint violations must

🚫 Not fixing — but I did fix the message, in da6ed39 and c1b8c0b.

The reason not to log _get_connector_path() here is that this branch is reached exactly when resolution failed. _get_connector_path() falls back to <bin>/<connector-name> in that case, so it would print a path that is confidently wrong: the file isn't there, and it isn't what we were looking for either. That's how the original misleading error in #290 read.

It now names the bin directory that was searched instead, which is the part that's actually true at that point, and the candidate script names travel in the exception context where they're useful for diagnosis. The Windows .exe suffix concern doesn't apply to a directory path.

☑️ Resolved in 2842edc — by deleting the script rather than fixing its lint.

It was a scratch reproduction artifact, and tests/integration_tests/test_console_script_discovery.py now covers the same ground as an actual test that CI runs. Keeping a hand-run script that duplicates a test is a maintenance liability, so the lint fix would have been polish on something that shouldn't be in the tree.

This PR fixes an installation-validation loop in VenvExecutor by resolving the connector’s actual installed console script name from package metadata (entry points) instead of assuming it matches the connector name. This improves compatibility with connectors whose console_scripts name differs from the connector slug.

Changes:

  • Add console-script discovery + caching to VenvExecutor, and update executable path resolution to use the discovered name.
  • Update ensure_installation() to validate installation based on successful console-script resolution rather than a hard-coded executable path check.
  • Add a regression fixture connector (source-wrong-exe), a unit regression test, and a small reproduction script.

☑️ Resolved in c1b8c0b. You were reading a genuine inconsistency, and the resolution went the other way from the obvious one: the plural key was correct and the singular return was the thing to change.

Discovery now returns all matching entry-point names (that's also what makes ambiguity detectable, in acf3a8e), so the method is _discover_console_script_names() and discovered_console_scripts holds a list. It's populated on both auto_fix=False and post-reinstall failure paths.

☑️ Resolved in 2842edc. Fixed by removing the script — the integration test covers the same scenario and runs in CI, so a lint-clean version of a hand-run duplicate wasn't worth keeping.

☑️ Resolved in acf3a8e. Same conclusion you reached, and this was the change I'd most want a maintainer to look at.

Rather than picking a candidate, resolution now declines: multiple candidates with none matching the connector name yields None, and the installation error surfaces with the candidate names in its context. Failing loudly beats launching some unrelated helper executable and failing later with a protocol error that points nowhere near the real cause.

☑️ Resolved in 2842edc. The test now takes pytest's tmp_path for its install_root, so the virtualenv is cleaned up by the fixture. It also moved to tests/integration_tests/ — it does a real install, so it was misfiled in the unit suite.

Include discovered console scripts in both installation error paths. When auto_fix=False, the error context omits discovered_console_scripts, so mismatched or ambiguous entry points do not report the names needed to diagnose the package configuration. Please include this diagnostic field in that branch as well.

  • This assertion is platform-dependent: on Windows, the installed console script is typically <name>.exe, and _get_connector_path().name will include the .exe suffix, causing the test to fail.
    assert executor._get_connector_path().name == expected_script_name  # noqa: SLF001
