Mailman Patch #668685: Corrects an error in SystemExit exception handling by $prefix/script/driver

Description

The code in the $prefix/scripts/driver script concedes that it is valid for a script it is supervising to exit using sys.exit rather than just returning from the main function.

However, if the script being supervised does use sys.exit, the driver script fails to pass on the output generated by the supervised script.

In the case of cgi scripts this means that an internal server error is reported by the http server because no output has been returned. And finding the reason for this is tedious!

Applicability

The changes made by this patch have been incorporated into Mailman 2.1.2 and thus it is not required for that and later releases.

This patch is applicable to Mailman 2.1 final and 2.1.1

Necessary Precursors

None

Changes Made
