I agree my patch for numeric fields is kind of temporary until a more
generic field system is introduced. Hopefully one with less iterating
over the fields list so much

[Trac-dev] Re: Ticket id before creating ticket

Hi Remy,

I parse the values in ITicketManipulator.validate_ticket(), because
ITicketChangeListener.ticket_changed won't be called if only the
budget info would be changed and nothing at the core ticket fields
itself. Isn't it that way?

When saving, I check in "post_process_request" if ticket and ticket-id
is correct.

Regards,
Franz

Heh, that's a good idea, my bad for not doing that in the first place.
Care to provide a patch?

This is usually a permission issue, more precisely the user running
trac-admin doesn't have permission to read trac.ini. I think we already
have an open ticket for this issue.

I can't help you there, I haven't ever used bzr.

I would do it with great pleasure, but I don't have yet the dev
environment for trac. I just thought about setting up one, but I need
some time... Any suggestion on how to set it up (I use eclipse with
pydev) in a efficient way will be more that welcome

oh, should I just use sudo trac-admin for the time being? or will I get
in other troubles?

Ok, here's the (very) short story, for Linux. Completely untested, of
course, but you should get the idea.

Create a checkout and set up the development environment:

  svn co http://svn.edgewall.org/repos/trac/trunk trac-trunk
  cd trac-trunk
  virtualenv venv
  . venv/bin/activate
  python setup.py develop

Create an environment:

  trac-admin env initenv
  trac-admin env permission add bogdan TRAC_ADMIN
  python contrib/htdigest.py -c htdigest trac bogdan

Run tracd in development mode on port 8000:

  tracd --http11 -p 8000 -a *,htdigest,trac env -r -s

... and hack away! tracd should auto-reload every time you save your
changes (you may have to restart it from time to time, for example when
you introduce a syntax error).

Every time you open a new shell, you have to activate the virtualenv:

  cd trac-trunk
  . venv/bin/activate

For more details, see:

  http://trac.edgewall.org/wiki/TracDev/DevelopmentEnvironmentSetup

I use that to sudo as the user running my web server.

[Trac-dev] post-commit hook

hi there,

I am setting up a trac env with svn, and i try to fix the hooks. I have
one question:

what should be the PYTHON_EGG_CACHE path?

the example reads:

#!/bin/sh
export PYTHON_EGG_CACHE="/path/to/cache/dir"
/usr/bin/trac-admin /var/lib/trac/YourProject changeset added "$1" "$2"

what should be "/path/to/cache/dir"?

thank you!

Wherever it fits: it is the path to a temporary directory where Trac
will extract the contents of the plugins (which are eggs == zip
files). It's really up to you. The directory should be read/writable
for the Trac application (ex: www-data if you use Apache or lighttpd
on  Ubuntu/Apache).

HTH,
Manu
