Missing import in deploy_trac.fcgi

Reported by: ebourg@… Owned by: Jun Omae
Priority: normal Milestone: 1.4.4
Component: general Version: 1.5.4
Severity: trivial Keywords:
Cc: Branch:
Release Notes:

Removed unnecessary exception handling from deploy_trac.fcgi template.

API Changes:
Internal Changes:

Description

deploy_trac.fcgi calls sys.stdout but doesn't import sys, the Apache error.log reports it:

NameError: name 'sys' is not defined: /var/www/projects/myproject/cgi-bin/trac.fcgi

Due to this stacktraces are displayed in the Apache log and not on the web page.

Good catch. Looks like it was overlooked in r17541 / #13403.

We should likely fix it before releasing 1.6.

The fastcgi script writes traceback of the exception which formatted "Content-Type: text/plain", however the output is received by the process that started the fascgi script (e.g. mod_fcgid), not the web client. So that I don't think the script needs to catch and format the exception.
