There were quite a few test cases in the gnu bug but I used this one: perl -e 'printf "33\n"x2 ."7\n"x31 ."1\n"' | src/sort -S1 -u and confirmed that the bug is fixed with coreutils version 8.13-3ubuntu3.1 from precise-proposed. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1038468 Title: data loss on sort -u To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/1038468/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello C, or anyone else affected, Accepted coreutils into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/coreutils/8.13-3ubuntu3.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

** Description changed: + [Impact] In some corner cases, 'sort -u' loses data. + [Test Case] http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9780 + [Regression Potential] It's coreutils, and a change to a vital system utility. The coreutils test suite should save us from the worst mistakes, but some paranoia would be justified. Perhaps booting a system with this change and using it for a day or two would be wise. + + Original report follows: + Last year a bug was reported to upstream coreutils [1] about problems on using 'sort -u'. Until recently, there was no known reproducing process; one such process was published last week [2]. Although triggering the bug can be said to be a non-completely trivial use case, data loss in 'sort' should be looked at as a serious issue. Today Jim Meyering committed what looks like the final touches of the fix (incidentally also solving a different issue (a free memory read), also in 'sort'. There are 4 commits affected, and they are shown starting in [3]. Given this is a data loss potential, I am opening this bug for all affected releases (this bug affects Coreutils 8.6 onwards -- Precise and Quantal).

This bug was fixed in the package coreutils - 8.13-3.2ubuntu1 --- coreutils (8.13-3.2ubuntu1) quantal; urgency=low * Resynchronise with Debian. Remaining changes: - [80] Make 'uname -i -p' return the real processor/hardware, instead of unknown. - Build-depend on gettext:any instead of on gettext, so that apt-get can properly resolve build-dependencies on the tool when cross-building. * Backport upstream patches to fix data-loss and free-memory read bugs in 'sort -u' (LP: #1038468). coreutils (8.13-3.2) unstable; urgency=low * Non-maintainer upload. * Don't declare separate build-arch/build-indep targets when they just fall through to the same common build rule, since they don't have correct target dependencies themselves. Closes: #670481. * Enable hardening build flags. Thanks to Moritz Muehlenhoff for the patch. Closes: #653743. * debian/patches/99_Werror-format-string.dpatch: fix the gnulib test suite so that it doesn't fail to build with hardening flags on. * Mark coreutils Multi-Arch: foreign. Thanks to Colin Watson. Closes: #649397. * debian/patches/99_tests-misc-sort-continue-Port-to-Fedora-15.dpatch: cherry-pick from upstream to fix a build failure whenever the build system happens to be holding an fd open, as happens when running in certain environments (e.g., Lucas's test rebuild farm, or bzr-builddeb).
