Bug#730768: [uscan] Allow a different compression scheme when repacking upstream tarballs

[Rafael Laboissiere]

Package: devscripts
Version: 2.13.4
Severity: wishlist
Tags: patch

Please, find enclosed below a patch for allowing uscan to use a different 
compression scheme when repacking upstream tarballs.  The patch should 
apply cleanly to the master branch of the Git repository, as today.

The changes introduced by this patch were originally done by Andreas 
Tille <tille at debian.org> and were discussed in the context of Bug#685787. 
I just merged the relevant changes from Andreas' private Git repository 
into the master branch of the Git repository of devscripts.

The --repack-compression option of uscan accepts now an argument that 
indicates the type of the compression that will be used when repacking the 
upstream tarball, either because there are files listed in the 
Files-Excluded field of debian/copyright or because the --repack option 
was given and there is need for repacking. The current alternatives are 
gz, bz, xz, and lzma.

The documentation in scripts/uscan.1 has been changed accordingly and 
the test in test/test_uscan has been extended to exercise the option 
--repack-compression=xz, which will repack the gz upstream tarball 
using xz.  For that to work, a build-dependency on xz-utils has also 
been added.

Best regards,

Rafael Laboissiere
