The bitmap implementation defines two template Bitmap classes. One optimized for 64-bit (default) wide bitmaps while the other is used for all other widths. In order to optimize the computations, Bitmap<64> class has defined its own member functions for bitmap operations, the other one, however, relies on mysys' bitmap implementation (mysys/my_bitmap.c). Issue 1: In case of non 64-bit Bitmap class, intersect() wrongly reset the received bitmap while initialising a new local bitmap structure (bitmap_init() clears the bitmap buffer) thus, the received bitmap was getting cleared. Fixed by initializing the local bitmap structure by using a temporary buffer and later copying the received bitmap to the initialised bitmap structure. Issue 2: The non 64-bit Bitmap class had the Iterator missing which caused compilation failure. Also added a cmake variable to hold the MAX_INDEXES value when supplied from the command prompt. (eg. cmake .. -DMAX_INDEXES=128U). Checks have been put in place to trigger build failure if MAX_INDEXES value is greater than 128. Test modifications: * Introduced include/have_max_indexes_[64|128].inc to facilitate skipping of tests for which the output differs with different MAX_INDEXES. * Introduced include/max_indexes.inc which would get modified by cmake to reflect the MAX_INDEXES value used to build the server. This file simply sets an mtr variable '$max_indexes' to show the MAX_INDEXES value, which will then be consumed by the above introduced include file. * Some tests (portions), dependent on MAX_INDEXES value, have been moved to separate test files. |
