Lars, is there a test case we can add for this that exercises mysqldump's lz4 capability, so that we know that it still functions?
** Description changed: MySQL 5.7 source package has liblz4-dev as a build-dep, but it isn't actually used because the build defaults to using a bundled version. [Impact] No known user impact at present (other than a small difference in binary footprint), but builds shouldn't use bundled libraries when it's available in the system. + + [racb] However a future security update in liblz4-dev will not update + MySQL. We fixed this in sid, and I think it's appropriate to backport + given that we've tested it in Yakkety. Add cmake flag -DWITH_LZ4=system to use the correct version. [Test case] * Build package * Run ldd on usr/lib/lz4_decompress and see it doesn't link in liblz4 from the system. [Regression potential] This change has been in Yakkety for some time (5.7.15-0ubuntu2). Database dump-related utils like mysqlpump and lz4_decompress could be impacted if any significant changes arise between the version of liblz4 available on user systems and what is used to test upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1631339 Title: Build with lz4 build-dep instead of bundled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1631339/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
