From e43de3ae4b33fb2fad7a4db042f413ecd7448545 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Thu, 28 Sep 2017 13:44:47 +0100 Subject: Improve logging of failures in matrixfederationclient * don't log exception types twice * not all exceptions have a meaningful 'message'. Use the repr rather than attempting to build a string ourselves. --- synapse/http/matrixfederationclient.py | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) diff --git a/synapse/http/matrixfederationclient.py b/synapse/http/matrixfederationclient.py index 747a791f83..6fc3a41c29 100644 --- a/synapse/http/matrixfederationclient.py +++ b/synapse/http/matrixfederationclient.py @@ -204,18 +204,15 @@ class MatrixFederationHttpClient(object): raise logger.warn( - "{%s} Sending request failed to %s: %s %s: %s - %s", + "{%s} Sending request failed to %s: %s %s: %s", txn_id, destination, method, url_bytes, - type(e).__name__, _flatten_response_never_received(e), ) - log_result = "%s - %s" % ( - type(e).__name__, _flatten_response_never_received(e), - ) + log_result = _flatten_response_never_received(e) if retries_left and not timeout: if long_retries: @@ -578,12 +575,14 @@ class _JsonProducer(object): def _flatten_response_never_received(e): if hasattr(e, "reasons"): - return ", ".join( + reasons = ", ".join( _flatten_response_never_received(f.value) for f in e.reasons ) + + return "%s:[%s]" % (type(e).__name__, reasons) else: - return "%s: %s" % (type(e).__name__, e.message,) + return repr(e) def check_content_type_is_json(headers): -- cgit 1.4.1
