Build # 983

Build Type

Committed by

Commit Message

Rename LegalMoveGenerator.__len__() to count() (fixes #226)

__len__ is used by list() to pre-allocate memory for the list.
Implementing __len__ basically claims that there is a more efficient
implementation than just iterating over all elements. This was indeed
the case in old python-chess versions, but even then it was less
efficient than just doing more allocations.

Thanks to Martin C. Doege for reporting this issue.

Implementing __length_hint__ with constant values between 32 and 64
does not seem to offer any speedup for list conversion.
