Here're the minutes from last week's meeting. Topics: * Use fast linking style:
The linker & glibc in 10.2 support the --hash-style=both (or just gnu) flag, which halves linking time [ still a major cost on all startup]. Unfortunately - it seems we only re-compiled glibc with this flag, and not all the other applications in the system :-) Risk wise this is a no-brainer, Red Hat are already shipping with --hash-style=gnu [ this is unfortunate since the binaries are then not back-compatible ]. We should most likely use --hash-style=both (at some small size penalty) - but after some time switch over to --hash-style=gnu to save size. The size difference is < 0.1 %. We will enable it by default. * libata per default (see minutes from last time - the partitioning question is still open) Moved to next meeting since one (critical) participant was missing. * Enable -fstack-protector for the new distros for every package by default Red Hat according to their press statements builds all of their distribution using -fstack-protector, the heuristic stack overflow detection. While we use -D_FORTIFY_SOURCE=2, this one only covers known arrays. I think we should also enable -fstack-protector for all packages. If we enable it by default in the compiler, all software will automatically get the benefit too. To analyze what effect this will have on performance we will run SPEC2000 and build one distribution with and one without the flag. -fstack-protector only adds protection to those functions that might overflow but not to all (-fstack-protector=all would instrument all). We will add it to RPM_OPT_FLAGS at the end of next week. AI: Run SPEC2000 AI: Build Alpha0plus without -fstack-protector and then rebuild with it. AI: Analyze performance and size differences. * Handling of compat packages These packages are inherited from old releases. The question is which libraries are really needed. AI: to ask on opensuse mailing list what is needed and start working on tracking list. Proposal: We consider having a library naming proposal that includes the version number so that people can easily grab an library RPM package from an older distro if needed. AI: write up proposal and discuss it on opensuse-packaging. * Avahi/mDNSResponder compatibility: Please assign all bugs to gnome-maintainers, they will look at it from March on. * Blacklisting /opt/gnome We can blacklist this path in autobuild and then packages still using /opt/gnome for FACTORY will not build. We will first prepare a list of packages still using it and later blacklist.
