Debconf not updating gui when ucf is used and detect a conffile-change

[Windkracht8]

Binary package hint: update-manager

1 Upgrade from dapper to edgy by running 'update-manager -c', while having previously changed a configuration file (fe: /etc/exports)
2 A 'debconf' window appears to ask if you want to keep the changed version of the file or if you want the package's version or if you want to see the difference between them.
3 Click on the 'distribution upgrade' window which then overlaps the 'debconf' window.
4 Bring the 'debconf' window back to the front.

The part of the 'debconf' window which was behind the 'distribution upgrade' window is not updating, thus leaving that part blanc.
Also when clicking 'applications', 'places' or 'system' which results in a menu overlapping the other part of the 'debconf' window. Makes the other part blanc.
Have a look at the screen shot (http://www.windkracht8.com/debconf_crash.png) for clarification.

Thanks for your bugreport.

I can confirm this problem here in a test-upgrade. The issue is that the ucf application is used to detect changes in the configuration file and presents a nice debconf frontend. Unfortunately it starts the diff (to show the differences) in the terminal that is hidden by default.

We should change ucf to not show stuff in the terminal under X but to invoke a new window to show the diff or to let dpkg deal with the conffile. This way it will send this information over the status-fd to the update-manager and that will present a nicer and better integrated conffile prompt with similar options.

Hi,

attached is a patch that uses debconf to display the diff. This avoids
that the GUI freeze when using the gnome debconf frontend.

It uses the "escape" capability of debconf, this is why I updated the
debconf version and removed cdebconf (it does not support this feature
currently).

Feedback is very welcome.

Cheers,
 Michael

P.S. I did the patch against a slightly older version, but it applies
fine to the latest version in unstable.

[Michael Vogt (mvo)]

I reject the update-manager task and move the 7.04 target to ucf.

[Michael Vogt (mvo)]

I send the debdiff upstream, hoping for feedback.

[Michael Vogt (mvo)]

This is fixed in the latest version of our ucf package in the archive.

Hi,

     The following change has been committed for this bug, and so the
  fix will be in the next upload.
===================================================================
2007-05-05 GMT Manoj Srivastava <email address hidden>

    Summary:
      Add support for displaying diffs using debconf itself
    Revision:
      ucf--devel--2.0--patch-2

    Users using a Graphical frontend are surprised when the display apparently
    just blocks when they ask to see a diff (or 3-way diff) of the
    configuration file being handled, when actually the diff is displayed on
    the terminal window ucf was run on. Until the debconf-escape utility and
    the escape CAPB support, db_subst ran into newline and line length
    issues. Patch from Michael Vogt.

    Closes: Bug#325576

    * ucf (show_diff): Added a function to show the diff using debconf

    * ucf (newsum): Use it

 ucf - Update Configuration File: preserves user changes to config files
Closes: 325576 421141
Changes:
 ucf (3.001) unstable; urgency=low
 .
   * Bug fix: "ucf: [INTL:ru] Russian debconf template translation", thanks
     to Yuri Kozlov (Closes: #421141).
   * Bug fix: "ucf: should use debconf to display the diff results", thanks
     to Gustavo Noronha Silva. Users using a Graphical frontend are
     surprised when the display apparently just blocks when they ask to see
     a diff (or 3-way diff) of the configuration file being handled, when
     actually the diff is displayed on the terminal window ucf was run
     on. Until the debconf-escape utility and the escape CAPB support,
     db_subst ran into newline and line length issues. Patch from Michael
     Vogt. (Closes: #325576).
   * From Michael Vogt's patch: use a debconf note for the diff. updated
     dependency of debconf to 1.4.72 (this is the version that supports the
     "escape" capability)
   * Left in the debconf-2.0 as is, since I am assuming anything that
     provides debconf-2.0 should be a drop in replacement, or that should
     be considered a bug. This is a change from Michael Vogt's patch.
