[serialization]Thread-safety of serialization lib
There are many places in serialization library that use a pattern like the following: static oserializer & instantiate(){ static oserializer instance; return instance; } AFAIK, not all compilers guarantee the initialization of a function level (or class member level) static variable is thread-safe. If I understand the code correctly, this essentially means that simultaneously serializing objects of the same type is not thread-safe. Am I missing something here? Thanks, Sean
Hmm - I would have to think about that. This would only be a problem in the case where multiple threads are simultaneously serializing to different archive instances. (I can't imagine multiple threads serializating to the same archive). Sorry I don't have much to say here. Robert Ramey Sean Huang wrote:

Robert, Did you mean same TYPE of archive? I think it would be common that multiple threads writes to arhives of same type. Sean From: "Robert Ramey" ramey@rrsd.com
