trac-admin needs a -q for quiet automated operation

[dbeckham-trac@…]

The trac-admin tool needs a -q option to make it shut up. When using it for automated operations, such as hotcopying for a backup, it's very chatty. Honestly, I'm not interested in it's success status, only it's failure so that I can act accordingly.

I'd like to add cast my vote as a proposed feature/fix as well.

anything happening on this ticket? I would like to have a quiet/silent output too.

[dkg-debian.org@…]

fwiw, I'd also like to see this happen.

Hey, there's a really easy fix for this!

trac-admin hotcopy… >/dev/null

I looked at patching -q into admin.py, but found that the bit in charge of actually running the commands sends errors to STDERR, and most commands send "informative output" to STDOUT. So you can easily discard STDOUT and be assured that you'll still hear about errors. I tested this with normal and failed hotcopies, and it works as advertised.

Recommend documenting this in a FAQ and WORKSFORME'ing this ticket.

Replying to demarco@maya.com:

trac-admin hotcopy… >/dev/null

That won't work so well on Windows. I wanted to test the stdout vs. stderr usage, so I made a simple patch to try out a -q option. That actually worked quite well.

trac-admin -q /path/to/env hotcopy for instance should now just print errors.

I'm just dropping the patch here for future reference in case someone wants to revive this issue - my only intention now was to see if I could make it work…
