Looks like we were right in time: https://www.kernel.org/happy-new-year-and-good-bye-bzip2.html Jean Le Friday 08 November 2013 à 14:19 +0100, Jean Delvare a écrit :
Hi all,
While kernel.org still offers bz2 archives for download, the discussion about dropping them and only leaving gz and xz is coming back every now and then. So I believe we should anticipate a future removal of bz2 archives and get our scripts ready to deal with xz-compressed archives now. If nothing else, that would encourage everyone to use xz-compressed archives whenever possible, which is a great saving of network bandwidth and storage space, plus decompression is twice as fast as with bz2.
Thus I'd like to add support for xz-compressed files to sequence-patch for a starter. I'm attaching the patch. It's only tested locally (outside of the suse network) so not all code paths were tested. Some more testing and review would be welcome.
We could also consider using xz to compress all tar files in tar-up.sh (and update the spec files accordingly.) This may make submission somewhat slower, as compressing with xz is significantly slower than with bzip2, but this would save some upload time, storage space in IBS/OBS and should also improve the build times by a small bit.
