Hi,

it seems empty directories sometimes get missing in dpkg.  Not sure yet
whether this is a bug and if so, in which package.

# cruft-ng
cruft report: Thu 29 Jun 2017 11:40:30 AM UTC
---- missing: dpkg ----
        /usr/lib/x86_64-linux-gnu/gio
        /usr/lib/x86_64-linux-gnu/gio/modules
[...]

They should be part of libglib2.0-0:

# dpkg -L libglib2.0-0:amd64 | grep /usr/lib/x86_64-linux-gnu/gio
/usr/lib/x86_64-linux-gnu/gio
/usr/lib/x86_64-linux-gnu/gio/modules

But no other files are registered in the path:

# dpkg -S '/usr/lib/x86_64-linux-gnu/gio*'
libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/gio/modules
libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/gio

Reinstalling the package did not help.

It would be nice to have a way to at least manually ignore these.

cheers,
Stefan

Hi,

When I took over cruft, I realized support for "filters-miss/" has never
been fully implemented; so it hasn't been re-implemented in cruft-ng:

See here: nothing
https://sources.debian.net/src/cruft/0.9.12/filters-miss/

libglib2.0-0 is still using deprecated CDBS build system;
a wild guess is that witching to modern Debhelper would
make this problem disapear.

This is likely more globaly usefull than implemeting manual
filtering of missing files in cruft/cruft-ng

Hi,

So you think debhelper would add postinst code to make sure those
directories are present? Because I see no other way the build system
would affect the outcome.

I found more use cases in the meantime...

- /etc/python2.7/sitecustomize.py doesn't get created on
  upgrade/reinstall
- the glib problem/bug sometimes also triggers with
  /usr/share/glib-2.0/schemas
- sometimes I explicitly don't want a config file to be present
  (signalled by renaming it to FOO.dpkg-dist). For example init scripts
  when I only want the binary, not the service. Or the many exim config
  snippets you don't want to activate.

cheers,
Stefan

apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall
libpython2.7-minimal

For this purpose, /etc/cruft/filters or more precisely /etc/cruft/filters-miss
should work with old cruft; I'll have a look on how to implement those
in cruft-ng.

Sample:
        /etc/logcheck/ignore.d.paranoid
        /etc/logcheck/ignore.d.workstation
        /etc/pkcs11
        /etc/pkcs11/modules

The files inside those directories are listed OK
and doesn't come up in cruft-ng output.


I'm adding an heuristic only for the files in /etc in latest release.

dpkg treats /etc differently from the rest,
for the files in /usr the individual packages should be fixed.

Greetings,

Alexandre
