HDF5 for Debian =============== On thread safety ---------------- Some general notes for developers: since 1.8 series HDF Group deprecates enabling the thread-safe option for the C library and at the same time supporting high level (HL), C++ and Fortran bindings. Those options cannot cohexist for safety because non C libraries wrapper are not thread-aware. Debian GNU/Linux still support a C thread-safe library and the alternative bindings, but it does not imply that the Debian distributed high level, C++ aand Fortranalibraries are thread-safe. For short: DO NOT use HL, C++ or Fortran bindings in multi-thread programs witihout providing yourself mutex infrastructure support for every wrapped function. You can use safely only the C binding in a multi-thread environment. That was not different in 1.6 series, just the issue was ignored. Now, you are warned. -- Francesco Paolo Lovergine <frankie@debian.org> Fri Jun 19 22:09:25 CEST 2009 1.10.0 and 1.10.1 compatibility ------------------------------- From HDF Group newsletter #153: HDF5 releases are always backward compatible. In general, they are also forward compatible in maintenance releases of a major release. However, the HDF5 - 1.10.0 maintenance release will NOT be able to read HDF5 - 1.10.1 files that contain a metadata cache image. The metadata cache image must be removed with the h5clear tool in order for HDF5 - 1.10.0 to read the file. -- Gilles Filippini <pini@debian.fr> Sat, 07 Oct 2017 14:02:39 +0200
