[petsc-dev] obscure changes in TSGetStages_Theta

[Zhang, Hong]

Done. Please check https://gitlab.com/petsc/petsc/-/merge_requests/3583

Sorry for any disturbance it caused. It was for the convenience of the adjoint implementation. The stages returned by TSGetStages_Theta currently do not reflect the true stages associated with these methods. The endpoint variant actually has two stages. This will be changed in a separate forthcoming MR, where TSRestoreStages() will be added and TSGetStages will return an array of vectors for the endpoint variant.

Hong,

I do not understand why you changed the behavior of TSGetStages_Theta https://gitlab.com/petsc/petsc/-/merge_requests/3500/diffs#a582bbaec75f4ae14bbf97d1d0404073ca89ff09_1194_1209 with this MR https://gitlab.com/petsc/petsc/-/merge_requests/3500

Now, the non-endpoint variant does no longer use th->X as stage!

Please revert this change
Thanks

Stefano
