[Pkg-libvirt-maintainers] Bug#753306: libvirt0: libvirt builds should include packager information

[Daniel P. Berrange]

Package: libvirt0
Version: 0.9.12.3-1
Severity: normal

Dear Maintainer,
The libvirt configure script has a special feature especially for distro
vendors to use when building binary packages which lets them encode a bit of
information about the builds, which then ends up in log files. This does not
appear to be used in Ubuntu builds which makes it impossible to determine
exactly which particular build of libvirt was used by the bug reporter

For example, on Debian currently if you turn on libvirt logging you'll see a
message like this:

  2014-06-27 15:12:33.274+0000: 20830: info : libvirt version: 0.9.12.3

By comparison on Fedora / RHEL systems you'd see something like this:

  2014-06-27 16:30:33.837+0000: 2454: info : libvirt version: 1.2.2,
package: 1.fc20 (Unknown, 2014-06-27-15:41:14, mustard.redhat.com)

In particular notice that it includes the precise RPM release number, so
that you can figure out exactly which binary package the bug reporter used.
eg on Debian this would any part of the version which Debian appends after
the main upstream version number

Debian packages could set this doing something like this

  when=`date +"%%F-%%T"`
  where=`hostname`
  who="Unknown" (or name of the person or entity doing the build)
  what="1" (or whatever current build is)

  ./configure --with-packager="$who $when $where" \
                         --with-packager-version="$what" \
                        ...other args to configure...

And then check that this has then propagated to the log messages
