Tom Lane	3606754da9	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

Tom Lane	220db7ccd8	Simplify and standardize conversions between TEXT datums and ordinary C strings. This patch introduces four support functions cstring_to_text, cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and two macros CStringGetTextDatum and TextDatumGetCString. A number of existing macros that provided variants on these themes were removed. Most of the places that need to make such conversions now require just one function or macro call, in place of the multiple notational layers that used to be needed. There are no longer any direct calls of textout or textin, and we got most of the places that were using handmade conversions via memcpy (there may be a few still lurking, though). This commit doesn't make any serious effort to eliminate transient memory leaks caused by detoasting toasted text objects before they reach text_to_cstring. We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few places where it was easy, but much more could be done. Brendan Jurd and Tom Lane	18 years ago
