- not much speed difference between SuperFastHash and Jenkin's lookup3 but
both are 5-10% faster than what is currently implemented in Foam::string,
albeit inlining probably helps there.
- TODO: integration with existing infrastructure
- compare iteratorBase == iteratorBase by value, not position
thus this works
list[a] == list[b] ...
- compare iterator == iteratorBase and const_iterator == iteratorBase
by position, not value. The inheritance rules means that this works:
iter == list.end() ...
this will compare positions:
iter == list[5];
Of course, this will still compare values:
*iter == list[5];
- make table power-of-two, but since it seems to give 1-2% performance
improvement, maybe forget it too.
- remove two-argument form of hashing classes and do the modulus direclty
within HashTable instead. This simplifies things a fair bit.
- migrate Hash<void*> from db/dlLibrary to primitives/hashes/Hash
- it was possible to create a PackedList::iterator from a
PackedList::const_iterator and violate const-ness
- added HashTable::printInfo for emitting some information
- changed default table sizes from 100 -> 128 in preparation for future
2^n table sizes
- much better performance on empty tables (4-6x speedup), neutral
performance change on filled tables. Since tableSize_ is non-zero when
nElmts_ is, there is no modulus zero problem.
- change system/controlDict to use functions {..} instead of functions (..);
* This is internally more efficient
- fixed formatting of system/controlDict functions entry
- pedantic change: use 'return 0' instead of 'return(0)' in the applications,
since return is a C/C++ keyword, not a function.
- this (now deprecated) idiom:
for (runTime++; !runTime.end(); runTime++) { ... }
has a few problems:
* stop-on-next-write will be off-by-one (ie, doesn't work)
* function objects are not executed on exit with runTime.end()
Fixing these problems is not really possible.
- this idiom
while (runTime.run())
{
runTime++;
...
}
works without the above problems.
- added class OSHA1stream for a stream-based calculation method
- dictionary gets digest() method
- dictionaryEntry tweak: avoid trailing space after dictionary keyword
- OSspecific: chmod() -> chMod(), even although it's not used anywhere
- ListOps get subset() and inplaceSubset() templated on BoolListType
- added UList<bool>::operator[](..) const specialization.
Returns false (actually pTraits<bool>::zero) for out-of-range elements.
This lets us use List<bool> with lazy evaluation and no noticeable
change in performance.
- use rcIndex() and fcIndex() wherever possible.
Could check if branching or modulus is faster for fcIndex().
- UList and FixedList get 'const T* cdata() const' and 'T* data()' members.
Similar to the STL front() and std::string::data() methods, they return a
pointer to the first element without needing to write '&myList[0]', recast
begin() or violate const-ness.
- removed the previously added fileName type(), isDir(), isFile() methods.
- added optional bool parameter to isFile() function to explicitly
enable/disable the check for gzip files.
- fixed minor bugginess where the default usage of isFile() would result in
false positive matches.
- be slightly more stringent and use isDir() and isFile() instead of
exists() function when we actually know the expected type.
- renamed surface regions (formerly patches or groups) to surfZone.
- added surfMesh, but without any of the patch information needed to make it
useful for finiteArea.
- promoted coordinateSystem transformation to surfaceMeshConvert and moved
old to surfaceMeshConvertTesting.
