New description:
This bug tracks the current status of the toric varieties code and the
interdependence of new patches, which should be applied '''on top of Sage
4.7'''. Any (properly ordered) part of positively reviewed patches can be
merged at any time, there is no need to "bundle tickets."
'''Applied to the current Sage alpha/beta/rc:'''
* #10943: Fan morphism fails on not full-dimensional fans
* #10140: Base sage.geometry.cone on the Parma Polyhedra Library (PPL)
* #10882: Add kernel fan to fan morphism
* #11302: Make it easier to construct a fan from a triangulation
* #10023: Compute Hilbert basis of cone
* #11200: Add fibration check to `FanMorphism`
* #10529: dimension() and is_smooth() for algebraic subschemes of toric
varieties
* #11481: LLL for degenerate matrices crashes
* #10540: Spec and patches for singular affine toric varieties /
algebraic schemes.
'''Applied to the next alpha/beta/rc:'''
* #11312: Speed up the computation of the Hilbert basis of a cone
* #11392: Toric ideals over fraction fields
'''Positively reviewed:'''
* #11558: Echelonize with transformation=True oddness for sparse matrix
* #11627: Turn Fan(discard_warning) into an error
These needs-review groups (separated by blank lines) can be applied
independently on top of the positively reviewed ones:
* #11385: Orbit closure as toric variety
* #11599: Wrap fan moriphism in toric morphism
* #10998: Categories for posets
* #11559: Speed up Posets and toric Chow group
* #11384: Construct the complex of a fan
* #11400: Add `PointCollection`
* #11429: Count integral points without PALP
* #11597: Dimension of the singular set
* #11627: Turn Fan(discard_warning) into an error
* #11634: Base Polyhedron on PPL by default
