Athough cube is a varlena type, nowhere was a detoasting of cube's value, so fix it. Add macroses DatumGetNDBOX, PG_GETARG_NDBOX and PG_RETURN_NDBOX. Backpatch for 8.2 too. Previous versions use version 0 calling conventions. And fmgr code detoast values for user-defined functions. 2007-03-08 05:25:18 +08:00			`/* $PostgreSQL: pgsql/contrib/cube/cubedata.h,v 1.7.2.1 2007/03/07 21:25:18 teodor Exp $ */`
Add CVS tag lines to files that were lacking them. 2006-03-11 12:38:42 +08:00
This is a comprehensive set of diffs (versus current CVS) that replaces those attached to the same message with the Earth Distance patches. Recent changes include changing the subscript in one place I forgot in the previous bugfix patch. A couple of added regression tests, which should help catch this mistake if it reappears. I also put in a limit of 100 dimensions in cube_large and cube_in to prevent making it easy to create very large cubes. Changing one define in cubedata.h will raise the limit if some needs more dimensions. Bruno Wolff III 2002-09-12 08:26:00 +08:00			`#define CUBE_MAX_DIM (100)`

The changes I have made are described in CHANGES. This was based on diffs to 7.3-devel and may not be applicable to 7.2. I have included a change covered by a previous bugfix patch I submitted (the problem with -.1 not being accepted by cube_in). It does not include a fix for the potential buffer overrun issue I reported for cube_yyerror in cubeparse.y. Bruno Wolff III 2002-08-30 07:03:58 +08:00			`double x[1];`
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-06 01:46:40 +08:00			`} NDBOX;`
