Package: dpkg-dev
Version: 1.14.16.6
Severity: important
File: /usr/bin/dpkg-shlibdeps
When a binary links against a library without using its symbols, and the
library is in a package providing .symbols file, dpkg-shlibdeps does put
a reference to the package in shlibs, but without a version number.
e.g.
$ dpkg-shlibdeps -v debian/libnss3-1d/usr/bin/test
Scanning debian/libnss3-1d/usr/bin/test (for Depends field)
Library libxml2.so.2 found in /usr/lib/libxml2.so.2
Library libc.so.6 found in /lib/libc.so.6
Looking up shlibs dependency of libc.so.6 provided by 'libc6'
Found libc6 (>= 2.7-1) in /var/lib/dpkg/info/libc6.shlibs
Using symbols file /var/lib/dpkg/info/libxml2.symbols for libxml2.so.2
dpkg-shlibdeps: warning: debian/libnss3-1d/usr/bin/test shouldn't be linked
with libxml2.so.2 (it uses none of its symbols).
$ cat debian/substvars
shlibs:Depends=libxml2 , libc6 (>= 2.7-1)
This is what happens without symbols file:
$ dpkg-shlibdeps -v debian/libnss3-1d/usr/bin/test
Scanning debian/libnss3-1d/usr/bin/test (for Depends field)
Library libxslt.so.1 found in /usr/lib/libxslt.so.1
Library libc.so.6 found in /lib/libc.so.6
Looking up shlibs dependency of libc.so.6 provided by 'libc6'
Found libc6 (>= 2.7-1) in /var/lib/dpkg/info/libc6.shlibs
Looking up shlibs dependency of libxslt.so.1 provided by 'libxslt1.1'
Found libxslt1.1 (>= 1.1.18) in /var/lib/dpkg/info/libxslt1.1.shlibs
dpkg-shlibdeps: warning: debian/libnss3-1d/usr/bin/test shouldn't be linked
with libxslt.so.1 (it uses none of its symbols).
$ cat debian/substvars
shlibs:Depends=libc6 (>= 2.7-1), libxslt1.1 (>= 1.1.18)
While this is not really a problem in such a simple case, it can become
problematic when library packages contain several different libraries,
one of which was not in previous versions of the package.
This is what happens in #474007: /usr/lib/purple-2/ssl-nss.so is linked
against libnssutil3 without using any of its symbols, but libnssutil3
doesn't exist before version 3.7.0~beta2-1 of the libnss3-1d package.
So dpkg-shlibdeps calculates the version dependency without taking into
account libnssutil3 and ends up writing a dependency on older versions,
which don't contain libnssutil3.
Surely, the nss.pc file could be enhanced to do the right thing, but that
won't prevent people linking against libnssutil3 anyways. And strangely,
in this case, -Wl,--as-needed *is* being used when linking
/usr/lib/purple-2/ssl-nss.so, but sadly, it still keeps the dependency
on libnssutil3 while not using its symbols.
Anyways, I think when using no symbol, the minimum version of all symbols
from the library should be used instead of not version. Or maybe the
symbols file should be ignored and the standard shlibs used.

Changes:

.
[ Guillem Jover ]
* Bump po4a version in Build-Depends to 0.33.1-1, as usage of UTF-8
in original man pages was causing build failures. Closes: #473498
* Add triggers documentation to dpkg-dev. Closes: #473449
* Add deb-triggers.5 and dpkg-trigger.1 man pages, and document new
statuses and options in dpkg.1.
.
[ Raphael Hertzog ]
* When dpkg-source builds a source package of Format: 2.0 or 3.0 (quilt) it
applies the patches before the build if
debian/patches/.dpkg-source-applied doesn't exist. This file is created
during extraction if patches are applied, and is auto-excluded from the
debian tarball. This enables on-the-fly conversion of source packages from
Format: 1.0 to Format: 3.0 (quilt) without manual intervention of the
user. This feature can be disabled with the option --no-preparation.
* The dpkg-source option --skip-patches disables application of patches
during extraction of source packages using Format: 2.0 or Format: 3.0
(quilt).
* Ensure the Files field is last in *.dsc and *.changes. This is a
work-around for some braindead dsc parsers (dupload and sbuild for
instance, see #473518 and #470440).
* Initialize dependencies for libraries having symbols files with the
smallest minimal version listed in the symbols file instead of using
an unversioned dependency. It's the only way to ensure the library
presence if it wasn't available in all versions of the package that ever
existed. Closes: #474079
* Don't use the -p option of diff for Format: 1.0 source packages.
dpkg-source of sarge doesn't accept data after @@. Closes: #474417
