- missed consistency in a few places.
- return nullptr (with automatic conversion to tmp) on failures
instead of tmp<....>(nullptr), for cleaner coding.
INT: add support for an 'immovable' tmp pointer
- this idea is from openfoam.org, to allow creation of a tmp that is
protected from having its memory reclaimed in field operations
ENH: tmp NewImmovable factory method, forwards as immovable/movable
- no-op implementations, but makes the call to
GeometricBoundaryField::evaluate() less dependent on PatchField type
- add updated()/manipulatedMatrix() methods to faePatchField,
fvsPatchField etc. These are mostly no-ops, but provide name
compatible with fvPatchField etc.
- similar to UPstream::parRun(), the setter returns the previous value.
The accessors are prefixed with 'comm':
Eg, commGlobal(), commWarn(), commWorld(), commSelf().
This distinguishes them from any existing variables (eg, worldComm)
and arguably more similar to MPI_COMM_WORLD etc...
If demand-driven communicators are added in the future, the function
call syntax can help encapsulate that.
Previously:
const label oldWarnComm = UPstream::warnComm;
const label oldWorldComm = UPstream::worldComm;
UPstream::warnComm = myComm;
UPstream::worldComm = myComm;
...
UPstream::warnComm = oldWarnComm;
UPstream::worldComm = oldWorldComm;
Now:
const label oldWarnComm = UPstream::commWarn(myComm);
const label oldWorldComm = UPstream::commWorld(myComm);
...
UPstream::commWarn(oldWarnComm);
UPstream::commWorld(oldWorldComm);
STYLE: check (warnComm >= 0) instead of (warnComm != -1)
- 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
- interpret as '-decomposeParDict xyz' for simpler scripting:
A empty value ("") as well as "none" or "false" values are ignored.
Eg,
unset decompDict
if some_condition; then decompDict=decomposeParDict-12; fi
runParallel -decompose-dict=$decompDict ...
ENH: more generous when scanning decomposeParDict for numberOfSubdomains
- assume file is in system/ directory if not otherwise found
- useful when regular contents are to be read via an IOobject and
returned.
Eg, dictionary propsDict(IOdictionary::readContents(dictIO));
vs. dictionary propsDict(static_cast<dictionary&&>(IOdictionary(dictIO)));
Commonly these would have simply been constructed directly as the
IO container:
eg, IOdictionary propsDict(dictIO);
However, that style may not ensure proper move semantics for return
types.
Now,
=====
labelList decomp(labelIOList::readContents(io));
... something
return decomp;
=====
Previously,
=====
labelIOList decomp(io);
// Hope for the best...
return decomp;
// Or be explicit and ensure elision occurs...
return labelList(std::move(static_cast<labelList&>(decomp)));
=====
Note:
labelList list(labelIOList(io));
looks like a good idea, but generally fails to compile
- the iterator/const_iterator now skip any nullptr entries,
which enables the following code to work even if the PtrList
contains nullptr:
for (const auto& intf : interfaces)
{
// Do something
...
}
- this is a change in behaviour compared to OpenFOAM-v2212 and earlier,
but is non-breaking:
* Lists without null entries will traverse exactly as before.
* Lists with null entries will now traverse correctly without
provoking a FatalError.
- allows unambiguous of count() for other classes.
Naming as per std::shared_ptr.
STYLE: qualify use_count() and unique() methods with the refCount base
- clearer/consistent meaning
- the null output adapter was previously used for the HashTables API
when HashSet actually stored key/value. Now that the node only
contains the key, having suppressed output is redundant, as is the
zero::null class (reduces clutter)
STYLE: replace one::minus dispatch in extendedEdgeMesh
GIT: remove Foam::nil typedef (deprecated since May-2017)
ENH: add pTraits and IO for std::int8_t
STYLE: cull some implicitly available includes
- pTraits.H is included by label/scalar etc
- zero.H is included by UList
STYLE: cull redundant forward declarations for Istream/Ostream
- in earlier versions: used 'fixed' notation
to force floating point numbers to be printed with at least
some decimal digits. However, in the meantime we are more
flexible with handling float/int input so remove this constraint.
- use ITstream::toString, which makes the string expansion of ${var}
and the expression expansion of $[var] consistent.
- other systems (eg, ARM64 linux with clang) do not have a separate
mpfr library configured so also check for mpfr (gmp is assumed to be
the same) and return corresponding cgal flavour (eg, header-no-mpfr)
