Package: python-apt
Version: 0.8.7
thanks
Hi,
currently loading of apt and aptsources packages will initialize new
configuration instances with apt_pkg.init(). If you have hooks to run
with package manager you will see them multiple times.
Please check if configuration is already initialized, e.g. with commmon
key "APT" (see patch below).
To reproduce this issue you can use following hook and snippet. Place
the one-liner 'echo' hook e.g. in /etc/apt/apt.conf.d/42testing):
DPkg::Pre-Install-Pkgs {"echo preinstallhook1 || exit 1";};
#!/usr/bin/env python
import apt_pkg
import apt # toggle
import aptsources # toggle
apt_pkg.init() # toggle
cache = apt_pkg.Cache()
depcache = apt_pkg.DepCache(cache)
pkgmanager = apt_pkg.PackageManager(depcache)
depcache.mark_delete(cache['apt'])
lock = apt_pkg.SystemLock()
with lock: # use lock to not remove anything
res = pkgmanager.do_install()
exit(res)
Expected behavior is to see this hook only one time.
Regards
Dominique Lasserre
