PackageKit Development

This page is to offer some tips for testing and debugging the conary backend for packagekit.

Misc

• Check out the latest git version for development.

• Here is some documentation (from Fedora project wiki) on building PackageKit and others from source.

Debugging information

• The logging module is used to show debugging info:

import logging as log
log.basicConfig(level=logging.DEBUG, format='%(asctime)s %(levelname)s %(message)s')

####
log.debug("Log phrase")

To remove logging, reset the debug level (or set to any level higher than DEBUG, like INFO):

level=logging.NOTSET

Build packagekit to run locally

Pass these flags to the ./configure script (change --prefix as you need):

NOCONFIGURE=yes ./autogen.sh
./configure --with-default-backend=conary  --disable-qt --enable-local --with-default-backend=conary --enable-conary /
 --enable-dummy --with-security-framework=polkit --disable-gtk-doc   --disable-browser-plugin  --disable-gstreamer-plugin  /
 --disable-ruck --disable-command-not-found --disable-gtk-module --disable-strict

make

(why "--disable-gtk-module --disable-command-not-found --disable-browser-plugin --disable-gstreamer-plugin"?) >> disable extra plugins for only run packagekit

Run packagekit without installing

• The conary backend is in backends/conary/ and the file conaryBackend.py acts as the entrance to the backend. The parameters that conaryBackend.py receives can be get from backends/conary/pk-backend-conary.c (simply search for 'conaryBackend.py').

So you can directly launch pkcon commands on the backend, shown as following.

Before you run the 'python conaryBackend.py <cmd>' commands, some preparation should be done first (TODO):

export NETWORK=
export BACKGROUND=

PackageKit:
pkcon refresh

backend:
python conaryBackend.py refresh-cache 0

Packagekit
pkcon search name gimp

backend:
python conaryBackend.py search-name "installed;available" gimp

PackageKit:
pkcon remove pastebinit

backend:
python conaryBackend.py remove-packages none "pastebinit:runtime;0.7-1-1;x86;/foresight.rpath.org@fl:2-qa/1222042924.172:0.7-1-1,1#x86"

Packagekit:
??

backend:
python conaryBackend.py update-packages "pastebinit;0.7-1-1;x86;/foresight.rpath.org@fl:2-qa/1222042924.172:0.7-1-1,1#x86"

PackageKit:
pkcon install pastebinit

backend:
python conaryBackend.py install-packages "pastebinit;0.7-1-1;x86;/foresight.rpath.org@fl:2-qa/1222042924.172:0.7-1-1,1#x86"

Packagekit:
pkcon resolve <app>

backend:
python conaryBackend.py resolve installed pastebinit
