From b6a7d49b6f1f7c494372fd1b9aab3982c9a299c7 Mon Sep 17 00:00:00 2001 From: Eric Eastwood Date: Tue, 16 May 2023 08:56:42 -0500 Subject: [PATCH] `traceback.format_exception(...)` usage that is compatible with Python 3.7 and 3.11 (#15599) * Usage that is compatible with Python 3.8 and 3.11 > Since Python 3.10, instead of passing value and tb, an exception object can be passed as the first argument. If value and tb are provided, the first argument is ignored in order to provide backwards compatibility. > > -- https://docs.python.org/3/library/traceback.html * Add changelog --- changelog.d/15599.bugfix | 1 + synapse/app/_base.py | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) create mode 100644 changelog.d/15599.bugfix diff --git a/changelog.d/15599.bugfix b/changelog.d/15599.bugfix new file mode 100644 index 000000000..b58af8ad5 --- /dev/null +++ b/changelog.d/15599.bugfix @@ -0,0 +1 @@ +Print full error and stack-trace of any exception that occurs during startup/initialization. diff --git a/synapse/app/_base.py b/synapse/app/_base.py index 4dfcf484f..936b1b043 100644 --- a/synapse/app/_base.py +++ b/synapse/app/_base.py @@ -214,7 +214,7 @@ def handle_startup_exception(e: Exception) -> NoReturn: # the reactor are written to the logs, followed by a summary to stderr. logger.exception("Exception during startup") - error_string = "".join(traceback.format_exception(e)) + error_string = "".join(traceback.format_exception(type(e), e, e.__traceback__)) indented_error_string = indent(error_string, " ") quit_with_error(
