Hi, I have collision-protect in my FEATURES and I had only gcc 3.4 installed. When I installed gcc 3.3, it overwrote two files (/sbin/fix_libtool_files.sh and /lib/rcscripts/awk/fixlafiles.awk) that were owned by gcc 3.4. I think portage should have blocked the installation of gcc 3.3. Reproducible: Always Steps to Reproduce: 1. emerge '=gcc-3.4*' 2. emerge -P gcc 3. emerge '=gcc-3.3*' Actual Results: Both gcc 3.3 and 3.4 are installed. Expected Results: gcc 3.3 should have been blocked.

Yeah, I haven't implemented the SLOT check yet.
Created attachment 45274 [details, diff] slot-check.patch Would this be enough? It looks like it...
That is not a valid check. Multiple slots per version are legal, just not well implemented in the database yet. They do gcc-3.3 and gcc-3.4 do not block because they do not affect the same files.

I changed the SLOT in a custom ebuild to "1", and when I pass it to emerge -pv, portage tells me it will replace the current version (with SLOT="0"), not install another version in another slot. Also, if multiple slots per version are legal, it would be impossible for a function to get the slot of an installed package when only knowing the name and version number, yet there is a function (getslot) which does this. I have no doubt that it is indended to be possible with a future version of portage, but are you sure it is allowed now? > They do gcc-3.3 and gcc-3.4 do not block because they do not > affect the same files. The two files I listed in my bug report are provided by both gcc 3.3 and gcc 3.4, and equery belongs confirmed this.
I had the same problem (but the other way around) when upgrading to gcc 3.4.4. Gcc 3.3.6 was installed, 3.4.4 installed as slotted version, some voodoo (emerge -e system, revdep-rebuild, etc) was done. On uninstalling gcc 3.3.6 /sbin/fix_libtool_files.sh got removed. I had to emerge gcc (3.4.4) again to have this file back. Same for /lib/rcscripts/awk/fixlafiles.awk of course. It seems /sbin/fix_libtool_files.sh is exactly the same file with the same md5sum in both versions. FWIW i also have collision-protect enabled in my features.
this is a bug in gcc itself, not portage i'll have the gcc issue fixed shortly
collision-protect is supposed to protect against this. That's the whole point of collision-protect...
oh, i read the report inversed ... i thought people were complaining that portage was flagging a collision between SLOT-ed packages and they wished for it to not do so
this is broken for binpkgs...but otherwise it's in -r3012, half-fixed in -r3339, completely fixed once I get a new patch. Released in 2.1_pre8-9ish, not sure which.
