Package: libtokyocabinet9 Version: 1.4.47-1 Severity: important TokyoCabinet under Debian unconditionally uses --enable-swab option, which has the following two effects:
- It forces tcucodec conf to say that the machine is big-endian (wrong). - It enforces the *non-native* data endianness in DB format. As a result, under Debian on little-endian machines Tokyo Cabinet uses big-endian format for database, and on big-endian machines Tokyo Cabinet uses little-endian format for database, which is - Incompatible with any other build of Tokyo Cabinet on any other operating system/Linux distribution for the same endianness. - Does not achieve database portability, which is declared as a goal for --enable-swab in debian/changelog - Unnecessary slow on all architectures.
