Tom Lane fd785441ff When using the OSSP UUID library, cache its uuid_t state object. ... The original coding in contrib/uuid-ossp created and destroyed a uuid_t object (or, in some cases, even two of them) each time it was called. This is not the intended usage: you're supposed to keep the uuid_t object around so that the library can cache its state across uses. (Other UUID libraries seem to keep equivalent state behind-the-scenes in static variables, but OSSP chose differently.) Aside from being quite inefficient, creating a new uuid_t loses knowledge of the previously generated UUID, which in theory could result in duplicate V1-style UUIDs being created on sufficiently fast machines. On at least some platforms, creating a new uuid_t also draws some entropy from /dev/urandom, leaving less for the rest of the system. This seems sufficiently unpleasant to justify back-patching this change.		12 years ago
