Traceback mailer[edit]

The python cgitb is an incredibly useful module. It is an enhanced traceback that includes states of the variables in use. Here's a script that will email us the information if/when one of our tools breaks.

First enable the module in each of your scripts:

# Change traceback handling and log to ~/public_html/cgi-bin/tracebacks/
import cgitb; cgitb.enable(logdir='./tracebacks/')

Automatic HTML mailing script:

#!/bin/bash
# This script will email all files from $LOGSDIR in HTML format
# Useful for automatic traceback reports

LOGSDIR=$HOME/public_html/cgi-bin/tracebacks

# Remove "Broken pipe" errors from Solaris installations
if [ "$(grep -s -l "Broken pipe" $LOGSDIR/*)" ]
then
    rm $(grep -s -l "Broken pipe" $LOGSDIR/*)
fi

# Dump the python exception html log
if [ "$(ls $LOGSDIR/)" ]
then
    cat $LOGSDIR/* | mutt -s "Python exceptions" \
      -e 'my_hdr From: Error reporter' \
      -e 'set copy=no' \
      -e 'set content_type="text/html"' \
      $(whoami)
    rm $LOGSDIR/*
fi
