Given how many packages use autoconf, I think so. -- I've already volunteered my tester to help shake out this change. It's actually a really good fit because of the autoconf/LTO interactions we had to sort out for F33/LTO. The plan is to spin it up next week. In simplest terms autoconf generated code to test for the existence of certain capabilities can be optimized away completely by LTO. This results in autoconf incorrectly claiming certain capabilities exist. This can cause packages to FTBFS or to even mis-behave at runtime. Thus it was critical to find these cases and deal with them as part of the LTO effort. So my tester has the ability to capture generated config.h files across its control and test builds and will report a failure if the generated config.h files differ (with an ability to exclude those where timestamps and such end up in the generated config.h files). In the test I'm going to run the only difference between the control and test build will be the version of autoconf. So the failures should give us a highly accurate picture of how autoconf-2.70 will impact the distribution as a whole. jeff _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
