- "buffered" corresponds to MPI_Bsend (buffered send),
whereas the old name "blocking" is misleading since the
regular MPI_Send also blocks until completion
(ie, buffer can be reused).
ENH: IPstream::read() returns std::streamsize instead of label (#3152)
- previously returned a 'label' but std::streamsize is consistent with
the input parameter and will help with later adjustments.
- use <label> instead of <int> for internal accounting of the message
size, for consistency with the underyling List<char> buffers used.
- improve handling for corner case of IPstream receive with
non-blocking, although this combination is not used anywhere
- manual revert for 44d0fbd594.
Unless required for post-processing the "value" entry should not
written if it is not mandatory for reading.
This is especially crucial with an 'empty' patch field where the
field (size 0) has a different size from the patch.
- the changes made align fvsPatchField behaviour with fvPatchField
- provides a more succinct way of writing
{fa,fv}PatchField<Type>::patchInternalField(*this)
as well as a consistent naming that can be used for patches derived
from valuePointPatchField
ENH: readGradientEntry helper method for fixedGradient conditions
- simplifies coding and logic.
- support different read construct modes for fixedGradient
- constructing with valueRequired as a bool is still supported,
but now also support more refined requirements
(eg, NO_READ, MUST_READ, LAZY_READ)
- continue with LAZY_READ for finite-area fields
