Mixing different versions (e.g., libgcc_s from lang/gcc7 with libgfortran from lang/gcc8) may destabilize runtime. Rebuild is necessary to ensure the consistent state, mainly for portmaster/portupgrade that don't rebuild every time dependency is upgraded. USE_GCC is implicitly set by USES=compiler on architectures stuck with GCC in base i.e., powerpc*/sparc64/mips*/riscv*. > This will lead to a delay of probably several days in getting updated > packages built for LATEST repos and will consume hours of CPU time for > everyone using poudriere or building from ports. According to 11.2 amd64 builder[1] /latest rarely finishes faster than in ~1.575 days as the median queue is ~8201 packages. GCC bump occured in r487333 build. During that time Boost (with bumps) and ImageMagick also updated, forcing a big number[2] of consumers rebuilt. [1] http://beefy9.nyi.freebsd.org/jail.html?mastername=112amd64-default [2] poudriere aggressively obsoletes packages if it detects dependency changed, taking down even indirect consumers in a chain reaction. $ poudriere bulk -j 112amd64 devel/magit www/emacs-w3m [...] Checking packages for incremental rebuild needs Deleting ImageMagick6-6.9.10.14_2,1.txz: new version: 6.9.10.16,1 Deleting emacs-26.1_4,3.txz: missing dependency: ImageMagick6-6.9.10.14_2,1 Deleting flim-emacs26-1.14.9_20,1.txz: missing dependency: emacs-26.1_4,3 Deleting ghub-emacs26-3.0.0.txz: missing dependency: emacs-26.1_4,3 Deleting graphql.el-emacs26-0.1.1.txz: missing dependency: emacs-26.1_4,3 Deleting magit-emacs26-2.90.1.txz: missing dependency: emacs-26.1_4,3 Deleting magit-popup-emacs26-2.12.4_1.txz: missing dependency: emacs-26.1_4,3 Deleting semi-emacs26-1.14.6_22.txz: missing dependency: emacs-26.1_4,3 Deleting treepy.el-emacs26-0.1.1.txz: missing dependency: emacs-26.1_4,3 Deleting with-editor-emacs26-2.8.0_1.txz: missing dependency: emacs-26.1_4,3 Deleting apel-emacs26-10.8_17.txz: missing dependency: emacs-26.1_4,3 Deleting dash.el-emacs26-2.14.1_1.txz: missing dependency: emacs-26.1_4,3 Deleting emacs-w3m-emacs26-1.4.632.b.20181110.txz: missing dependency: emacs-26.1_4,3 Deleting stale symlinks... done Deleting empty directories... done Cleaning the build queue Sanity checking build queue Processing PRIORITY_BOOST Balancing pool Recording filesystem state for prepkg... done Building 13 packages using 8 builders [...]
