See also http://bugs.gentoo.org/show_bug.cgi?id=89475 about original problem with bzip2 implementation changes and checksum errors, and http://bugs.gentoo.org/show_bug.cgi?id=160283 about bzip2-1.0.4 availablilty. It is clear that original intention of fix available in deltup sources (concerning bzip2 algorithm changes in bzip2-1.0.3) was to treat all bzip2 versions >= 1.0.3 as "new format". Seems like there is a typo in implementation of that fix, which introduces strict matching for bzip2-1.0.3 version and makes bzip2-1.0.4 a problem. Solution is to match for ">=1.0.3" version (one-liner). Patch attached, please apply (while upstream fix is not available). Reproducible: Always Steps to Reproduce: Prepare: 1. Follow http://gentoo-wiki.com/TIP_Gentoo_for_dialup_users to set up getdelta.sh to fetch package changes via deltup. 2. install bzip2-1.0.4 package Reproduce e.g. with libX11 update: 3. make sure /usr/portage/distfiles/libX11-1.0.3.tar.bz2 is the latest libX11 package available, and portage tree has x11-libs/libX11-1.1.1 so you have an upgrade and need to download new source 4. emerge -f libX11 Actual Results: libX11-1.0.3.tar.bz2-libX11-1.1.1.tar.bz2.dtu is found and applied without errors, resulting in libX11-1.1.1.tar.bz2 package in the process deltup reports that bzip2_old is used for recompression (which is bad, because dtu file requires at least bzip2-1.0.3) portage refuses the result because of checksum mismatch Expected Results: libX11-1.0.3.tar.bz2-libX11-1.1.1.tar.bz2.dtu is found and applied without errors, resulting in libX11-1.1.1.tar.bz2 package in the process deltup reports that bzip2 is used for recompression (which is now OK, bzip2-1.0.4 is correctly used) portage accepts the result, checksums are OK
Created attachment 107673 [details, diff] patch to check for bzip2 >= 1.0.3
already fixed in -r1, thank you very much for reporting and fixing this!
