20-25: ⚡ Quick winConsider binding and using the connection explicitly.
The context manager opens a connection but doesn't bind it to a variable, then
inspect(engine)is called which may obtain a different connection from the pool. While the current code works correctly, it would be clearer to bind the connection and pass it directly toinspect().♻️ Proposed refactor for clarity

Pull request overview
Fixes an exception-masking bug in check_external_config_db() (used by the Docker entrypoint) so an unreachable external config DB results in a clean False rather than an unhandled exception.
Changes:
- Replace manual connection close logic with a connection context manager and dispose the SQLAlchemy engine.
- Add a release note entry for the external config DB unreachable crash.

Cannot merge in current shape — the PR is built against a stale base. The - hunk removes a finally: connection.close() block from a version of check_external_config_db.py that doesn't match current master:
- master line 10:
from db_utils import normalize_database_uri(absent in PR base) - master line 19:
create_engine(normalize_database_uri(database_uri))— PR base uses barecreate_engine(database_uri) - master line 20:
connection = Noneguard already added — PR base has no guard
If this merges as-is it silently drops normalize_database_uri, regressing the #9984 fix that handled 'url'-quoted URIs from config_distro.py. The NameError is also already partially fixed on master via the None guard, so the headline motivation is partly moot.
Please rebase, preserve normalize_database_uri, and remove the dead return False after return inspect(...) on master line 24 while you're in there.
Separately worth noting (not introduced by this PR, but worth a follow-up): the entrypoint suppresses Python stderr via 2>/dev/null and falls through to first-launch setup on any failure. except Exception: return False makes the silent-fallback explicit but doesn't address that misconfiguration produces no visible signal.

@asheshv the branch is rebased onto current master now (head is 76740f8).
With those already on master, what this PR still contributes is turning any failure to reach the database - not just the NameError - into an explicit Tests cover an unreachable host, a malformed URI, and a reachable database with and without the Noted on the stderr-suppression point in the entrypoint - agreed that's worth a follow-up, but leaving it out of scope here. Ready for another look when you have a chance. |
The commit message is worth restating because most of the original motivation has already been fixed on master: normalize_database_uri() and the "connection = None" guard landed with pgadmin-org#9984, so the NameError itself is gone. What remains is that any failure to reach the database still propagates out of check_external_config_db() rather than being answered, along with the unreachable "return False" left stranded after the return above it. The container entrypoint currently papers over that by discarding stderr and keeping its own "False" default when the helper prints nothing, so the behaviour a user sees does not change. Making the fallback explicit does mean the helper now honours its contract for any other caller, and the comment records why False is the right answer: first launch has to proceed and create the user from PGADMIN_DEFAULT_EMAIL and PGADMIN_DEFAULT_PASSWORD, rather than leaving an installation nobody can log in to. create_engine() is inside the try as well, since it is what rejects a malformed URI, and the engine is now disposed rather than only its connection being closed, so a failed check does not leave a pool behind. Tests cover an unreachable host, a malformed URI and a reachable database with and without a server table. They import the module the way the entrypoint does, as a top level module from its own directory, so they also fail if that arrangement is broken.
…cking _uri() built the test URI by dropping the configured host straight into the authority component. On the Linux/macOS CI runners that host is a Unix domain socket directory, and a "/" there is parsed as the start of the path rather than part of the host, leaving the host/port undetermined and the database name mangled - which is why the "reachable database with a server table" scenario failed there while passing on Windows (TCP host). Detect a socket-directory host and use libpq's query-parameter form instead, and URL-encode the username and password in both branches. Also record self.created_table immediately after CREATE TABLE succeeds rather than after the isolation-level restore and commit, so tearDown still drops the table if either of those later steps fails; tearDown's DROP now uses IF EXISTS to stay safe either way.
inspect(engine) checks out its own connection from the pool, so the one opened by the context manager was never used and the check could open two. Binding the inspector to the managed connection means has_table() runs on the connection whose lifetime the with block controls.

Problem
check_external_config_db()is used by the container entrypoint to decide whether to run first-launch user setup. #9984 already fixed the originalNameError(it addednormalize_database_uri()and aconnection = Noneguard), but any failure to reach the database, whether an unreachable host, a wrong password or a malformed URI, still propagates out of the function as an exception rather than being answered. The entrypoint only copes because it discards stderr and falls back to its ownFalsedefault.Fix
create_engine()moves inside thetry, since it is what rejects a malformed URI, and any exception now returnsFalse, with a comment explaining why that is the right answer for first launch.finallyso a failed check does not leave a pool behind.return Falseafter thereturn inspect(...)is gone.Tests
web/pgadmin/utils/tests/test_check_external_config_db.pycovers an unreachable host, a malformed URI and a reachable database with and without aservertable, importing the module the way the entrypoint does. All pass locally against PostgreSQL 18.Summary by CodeRabbit
