Hi Steffen Hoffmann,
Thanks for you reply. It gives me a starting pont.
I followed your suggestion. What I did is:
1. Create MyTicketChangeScriptCaller.py (chmod 755) in my <env>/plugins
folder. Below is its content:
> from subprocess import Popen
> from trac.core import *
> from trac.config import Option
> from trac.ticket import ITicketChangeListener
> class TicketChangeScript(Component):
> """ Calling a script file on ticket changes."""
> implements(ITicketChangeListener)
> script = Option('ticket_change_script', 'call', '',
> doc="/usr/local/bin/test.sh")
> # ITicketChangeListener Interface
> def ticket_created(self, ticket):
> self._call(ticket, 'created')
> def ticket_changed(self, ticket, comment, author, old_values):
> self._call(ticket, 'modified')
> # def ticket_deleted(self, ticket):
> # # Beware: We may not have all ticket properties here,
> # # just ticket number.
> # self._call(ticket, 'deleted')
> def _call(self, tkt, tkt_change):
> Popen([' '.join([script, tkt.id, tkt['summary'], tkt_change])],
> shell=True)
2. Add these lines in my trac.ini file
> [ticket_change_script]
> call = /usr/local/bin/test.sh

3. Create a test shell script /usr/local/bin/test.sh (chmod 755), which
doesn't need a common arguments. Below is its content:
> #!/bin/sh
> tkt_id=$1
> tkt_summary=$2
> tkt_status=$3
> echo $tkt_id > /tmp/test
> echo $tkt_summary >> /tmp/test
> echo $tkt_status >> /tmp/test
For my understanding when I create/modify a ticket in Trac , I should
get something in /tmp/test file. But there is nothing, even the file
(/tmp/test) wasn't created.
What I missed from your explanation?
Thank you for your patience and help
