[Piuparts-devel] reporting partial upgrade file overwrite bugs

[Andreas Beckmann]

Hi,

looks like the most common bug we find with potential-cross-conflicts.py
are file overwrites during partial upgrades:

$ ./show-status cross-wheezy-sid | grep overw

These are usually caused by moving files around between binary packages
of the same source package, so they don't show up during intra-
distribution checks.

IMO these bugs should be reported against the new binary package
(rightmost column) with an Affects: overwritten-package, ...

Ralf, you you use some script to prepare your bug reports?
Do you want to copy+adjust your file-overwrite template for this case?
Should we use the same usertag or a new one?

I have the following files that should help preparing a bug report by
filling some template automatically:
 * candidate file
    - file name provides package names and versions
      (pkgold=verold_pkgnew=vernew)
    - contains list of files
 * piuparts logfile
    - grep -C 5 'trying to overwrite' $logfile | sed '/^--/,$ d'
      reports the interesting lines

Anyone who wants to do this?
