Occasionally, if both the partition_pruning and partition_range tests are run sequentially against the IBMDB2I engine, the partition_range test will fail. Compiler padding on a 64-bit build allowed garbage data in the hash key used for caching open iconv descriptors. As a result, cached descriptors were not found, and multiple duplicate iconv descriptors were opened for a single character set. Eventually, the maximum number of open iconv descriptors was reached, and further iconv_open() calls would fail, leading the storage engine to report incorrectly that the character set was not supported. This patch widens the 16-bit members of the hash key to 32 bits to eliminate compiler padding. The entire length of the hash key is now initialized correctly on both 32-bit and 64-bit builds. storage/ibmdb2i/db2i_charsetSupport.cc: Bug#44856 IBMDB2I gives misleading 2504 error widen the 16-bit members of the hash key to 32 bits to eliminate compiler padding. |
