Hi,
To the best of my knowledge no one is actively working on any of those
items at the moment, although some has shown interest in SpanQueries. If
someone does - please let us all know.
So if you implement any of them and can contribute back this will really
help.
Re #3 - you are right, I originally implemented it as a while loop and
in commit ac29f3cbc it was converted to for. This was also spotted by
Veit. I fixed and committed to master. If there are tests in Java for
this class that weren't ported yet to cl_test, I strongly suggest to
port them to verify this fix seals all leaks from this class.
Re #4 - there isn't one, but it shouldn't be too difficult to add one,
or you can use ValueArray and delete or decref them yourself. We are
about to finish work on the smart_pointers branch, which does
refcounting more efficiently using Boost. If you can work with that
instead and provide feedback, that would be even better.
What do you mean by "the Array implementation does hardly allow reusing
already allocated arrays"?
Itamar.
