Print full startup/initialization error (#15569) I found the error in the **Before** really vague and obtuse and didn't realize port `5432` corresponded to the Postgres port until searching the codebase. It says to check the logs but that wasn't my first instinct. It's just more obvious if we just print the full thing which gives context of the error type and the traceback to the relevant area of code. #### Before ``` $ poetry run python -m synapse.app.homeserver -c homeserver.yaml ********************************************************************************** Error during initialisation: connection to server at "localhost" (::1), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? There may be more information in the logs. ********************************************************************************** ``` #### After ```sh $ poetry run python -m synapse.app.homeserver -c homeserver.yaml ********************************************************************************** Error during initialisation: Traceback (most recent call last): File "/home/eric/Documents/github/element/synapse/synapse/app/homeserver.py", line 352, in setup hs.setup() File "/home/eric/Documents/github/element/synapse/synapse/server.py", line 337, in setup self.datastores = Databases(self.DATASTORE_CLASS, self) File "/home/eric/Documents/github/element/synapse/synapse/storage/databases/__init__.py", line 65, in __init__ with make_conn(database_config, engine, "startup") as db_conn: File "/home/eric/Documents/github/element/synapse/synapse/storage/database.py", line 161, in make_conn native_db_conn = engine.module.connect(**db_params) File "/home/eric/.cache/pypoetry/virtualenvs/matrix-synapse-xCtC9ulO-py3.10/lib/python3.10/site-packages/psycopg2/__init__.py", line 122, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) psycopg2.OperationalError: connection to server at "localhost" (::1), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections?
