• Status: RESOLVED FIXED
• Product: Portage Development

[Description John N. Laliberte (RETIRED) 2006-05-11 12:12:53 UTC]

was troubleshooting a problem with antarus about a binary package emerge.

logfile is in URL.

"
antarus AllanonJL|W: basically say that the SLOT detection code in collision detect is broken.
antarus AllanonJL|W: it's pruning packages from the owner search that shouldn't be pruned due to settings["SLOT"] being wrong
"

Let me know if you need more information.

basic steps are:

emerge a newer revision of a package you have installed using a binhost.

watch it fail due to collision-protect.

mysettings["SLOT"] was wrong when binpkg's were being merged.

Fixed in -r3339, thanks a bunch to John for being patient while I debugged and for testing the patch.

[Comment 3 Alec Warner (RETIRED) 2006-05-11 12:48:57 UTC]

tsk tsk, I apparently can't click worth a damn, sorry for the bugspam...

brian pointed out this should be set in doebuild, so I will move it.

It's already done in doebuild_environment().  If that's not working then there's a bug in bindbapi...

Yes so I noticed after taking another look, however it appears emerge is just being daft..

not being called from doebuild = nothing being set, which is scary in and of itself...Not sure how I managed to miss that the first dozen times i was looking at the where output.

[Comment 7 Zac Medico 2006-05-12 11:38:38 UTC]

This was already fixed in svn r3301 (not yet released in pre10-r5).  I wasn't trying to fix this bug, but did so by luck.  So, r3339 isn't needed and I'll revert it.

[Comment 8 Zac Medico 2006-05-13 15:25:53 UTC]

This has been released in 2.1_rc1.
