I tested QDBM on BSD platforms and found problems about using mmap. On OpenBSD(i386), the test suite failed by `no item' error. This problem is not caused if QDBM was built with `--enable-nommap'. When using `mmap', the system call `write' seems not to work right way. Though the return value is 0, nil codes are written instead of data of the parameter. On FreeBSD(Alpha), the test suite failed by `memory mapping' error. This problem is also not caused if QDBM was built with `--enable-nommap'. `msync' fails if the size of mapping region is larger than about 1.2MB (bnum is 16300). Does anyone know the reason for these problems? For the nonce, the next version will disable mmap features as for the two platforms. Regards. // Mikio Hirabayashi --6c2NcOVqGQ03X4Wi--
