[pkg-GNUstep-maintainers] Bug#262851: rebuild with libtiff4, upload with urgency=medium

[Jay Berkenbilt]

Severity: Serious
Justification: FTBFS
Package: libgnustep-gui0-dev

As of version 0.9.3-3, package libgnustep-gui0-dev has not yet been
rebuilt with libtiff4.  Please rebuild the package with libtiff4 and
upload with urgency=medium.  Note that taking care of this problem is
a prerequisite for ultimately being included in sarge, even if a
version of this package already appears in testing.  No source changes
are required; updating dependencies and rebuilding should be
sufficient.  All packages not uploaded within several days will be
NMUed.  Many thanks for your patience and cooperation.

All maintainers and package tracking system addresses for affected
packages have been previously notified.  As a reminder, here is a copy
of that original notification (slightly edited).  Note that since this
was sent out, there have been various other threads on both
debian-devel and debian-release.

An accidental ABI change was made in libtiff (upstream) between
version 3.5.7 (the version currently in sarge) and 3.6.1 (the version
currently in sid).  This has resulted in 10 merged release-critical
bugs filed against libtiff3g for packages that don't work correctly
when compiled with one of these versions and run with the other.

Unfortunately, since this problem has been left unresolved for some
time, many packages have been compiled with 3.6.1 in sid and have
transitioned into sarge where they may not work correctly with 3.5.7.
Some of these packages are known to work correctly in sid but not in
sarge.  Transitioning version 3.6.1 of libtiff into sarge is
unaccaptable because it would create incompatbility with woody and
third-party applications that were compiled with libtiff 3.5.7 or
earlier.

To ensure that this problem is fully corrected, sarge will not contain
a libtiff.so.3.  Version 3.6.1 of libtiff will be included as
libtiff.so.4, with support of upstream.  All packages that depend upon
libtiff3g or libtiff3g-dev will have to be rebuilt with libtiff4 or
libtiff4-dev.  Doing this update is a precondition for the package
being included in sarge.  Please note that there were no source-level
interface changes between 3.5.7 and 3.6.1, so it should be sufficient
to just update the dependencies and recompile.  Use urgency=medium
when making this change.

It will be important for these changes to be made quickly as, once the
new tiff packages are uploaded, many packages will no longer be
installable or buildable from source.  As such, release-critical bugs
(severity serous, justification FTBFS) will be filed against any
package that still depends upon libtiff3g or libtiff3g-dev a few days
after the upload of the new tiff packages, and any packages that have
not been fixed and uploaded within approximately one week will be
NMUed.  Once all packages that depend upon libtiff have appeared in
sid, all these packages will be able to transition into sarge
together.
