If you insert more than 4 billion records into a bloom filter, it is possible to get an error:
[1387236931:360057][5093:00f77f1ee07f0000], file:dbbench_wt-001492.bf, cursor.insert: Bulk bitmap load not aligned on a byte boundary: Invalid argument
The code that is broken is in src/bloom/bloom.c:
/* * Shave off some bytes for pure paranoia, in case WiredTiger * reserves some special sizes. Choose a value so that if * we do multiple inserts, it will be on an byte boundary. */ values.size = (uint32_t)WT_MIN(bloom->m - i, UINT32_MAX - 128); c->set_value(c, &values); WT_ERR(c->insert(c));
The UINT32_MAX - 128 value isn't a multiple of 8.
