Can I merge #9470 and #9326 now, or should I wait until every ticket has a positive review?

comment:3 follow-up: Changed 4 years ago by vbraun

#9470 and #9326 are ready to be merged, but I thought that 4.5.2 is in feature freeze now?

comment:4 in reply to: ↑ 3 Changed 4 years ago by mpatel

Replying to vbraun:

#9470 and #9326 are ready to be merged, but I thought that 4.5.2 is in feature freeze now?

Indeed, we'll release 4.5.2 very soon. I've been preparing a 4.5.3.alpha0.

I'll put bugs in front of toric divisors, since they have chances to be settled quickly.

I sneaked in yet another patch in front of toric divisors, in case it will be useful for Kaehler/Mori? cones (maybe not due to dimension limitations), but so far it is independent of #9337 and can be shifted down.

trac_9664_add_toric_potter.patch depends on trac_9972_add_toric_lattice_morphisms.patch. No logical dependency, but thats how the patch works out. I don't think order matters too much on that one, just wanted to get it right.

No more dependence ;-)

Sorry for temporarily making #10513 a dependency. This ticket isn't ready, yet. Thus I reoved the dependency again.

comment:40 Changed 4 years ago by novoselt

  • Description modified (diff)

Tried to make all dependencies and especially their absences more clear.

Volker, I am a little confused by comments on #8169 and #9918 - do they depend on/conflict with each other somehow?

comment:41 Changed 4 years ago by vbraun

#9918 uses the TOPCOM spkg (in #8169) if it is available, and falls back to its own implementation if not. So there is no dependency either way. Except that applying #8169 without #9918 would be meaningless as there would be nothing in the sage library to use TOPCOM.

comment:42 Changed 4 years ago by novoselt

So none of the patches of #8169 should be applied, it just provides an optional package, correct?

comment:43 Changed 4 years ago by vbraun

Yes, none of the patches in #8169 should be applied.
