* Redefine Datum as uintptr_t, instead of unsigned long.Tom Lane2009-12-31
| | | | | | | This is more in keeping with modern practice, and is a first step towards porting to Win64 (which has sizeof(pointer) > sizeof(long)). Tsutomu Yamada, Magnus Hagander, Tom Lane

* Allow float8, int8, and related datatypes to be passed by value on machinesTom Lane2008-04-21
| | | | | | | | | | where Datum is 8 bytes wide. Since this will break old-style C functions (those still using version 0 calling convention) that have arguments or results of these types, provide a configure option to disable it and retain the old pass-by-reference behavior. Likewise, provide a configure option to disable the recently-committed float4 pass-by-value change. Zoltan Boszormenyi, plus configurability stuff by me.
* Modify the float4 datatype to be pass-by-val. Along the way, remove the lastAlvaro Herrera2008-04-18
| | | | | | | | | | | | | | | uses of the long-deprecated float32 in contrib/seg; the definitions themselves are still there, but no longer used. fmgr/README updated to match. I added a CREATE FUNCTION to account for existing seg_center() code in seg.c too, and some tests for it and the neighbor functions. At the same time, remove checks for NULL which are not needed (because the functions are declared STRICT). I had to do some adjustments to contrib's btree_gist too. The choices for representation there are not ideal for changing the underlying types :-( Original patch by Zoltan Boszormenyi, with some adjustments by me.
* Reduce the need for frontend programs to include "postgres.h" by refactoringTom Lane2008-03-27
| | | | | | | | | | | | inclusions in src/include/catalog/*.h files. The main idea here is to push function declarations for src/backend/catalog/*.c files into separate headers, rather than sticking them into the corresponding catalog definition file as has been done in the past. This commit only carries out that idea fully for pg_proc, pg_type and pg_conversion, but that's enough for the moment --- if pg_list.h ever becomes unsafe for frontend code to include, we'll need to work a bit more.

* Avoid assuming that struct varattrib_pointer doesn't get padded by theTom Lane2007-10-01
| | | | | | | | | | | compiler --- at least on ARM, it does. I suspect that the varvarlena patch has been creating larger-than-intended toast pointers all along on ARM, but it wasn't exposed until the latest tweak added some Asserts that calculated the expected size in a different way. We could probably have fixed this by adding __attribute__((packed)) as is done for ItemPointerData, but struct varattrib_pointer isn't really all that useful anyway, so it seems cleanest to just get rid of it and have only struct varattrib_1b_e. Per results from buildfarm member quagga.
* Add an extra header byte to TOAST-pointer datums to represent their sizeTom Lane2007-09-30
| | | | | | | explicitly. This means a TOAST pointer takes 18 bytes instead of 17 --- still smaller than in 8.2 --- which seems a good tradeoff to ensure we won't have painted ourselves into a corner if we want to support multiple types of TOAST pointer later on. Per discussion with Greg Stark.
* Fix typos in two comments. Spotted by Brendan JurdTom Lane2007-09-27

* Rename DLLIMPORT macro to PGDLLIMPORT to avoid conflict withMagnus Hagander2007-07-25

* Update comments for PG_DETOAST_PACKED and VARDATA_ANY on a structuresBruce Momjian2007-05-15
| | | | | | | | | that require alignment. Add a paragraph to the "User-Defined Types" chapter on using these macros since it seems like they're a hit. Gregory Stark
* A few fixups in error handling: mark pg_re_throw() as noreturn for gcc,Tom Lane2007-05-04
| | | | | | | and for other compilers, insert a dummy exit() call so that they understand PG_RE_THROW() doesn't return. Insert fflush(stderr) in ExceptionalCondition, per recent buildfarm evidence that that might not happen automatically on some platforms. And const-ify ExceptionalCondition's declaration while at it.
* Support varlena fields with single-byte headers and unaligned storage.Tom Lane2007-04-06
| | | | | | | | | This commit breaks any code that assumes that the mere act of forming a tuple (without writing it to disk) does not "toast" any fields. While all available regression tests pass, I'm not totally sure that we've fixed every nook and cranny, especially in contrib. Greg Stark with some help from Tom Lane
* Adjust DatumGetBool macro so that it isn't fooled by garbage in the DatumTom Lane2007-03-23
| | | | | | | | | | to the left of the actual bool value. While in most cases there won't be any, our support for old-style user-defined functions violates the C spec to the extent of calling functions that might return char or short through a function pointer declared to return "char *", which we then coerce to Datum. It is not surprising that the result might contain garbage high-order bits ... what is surprising is that we didn't see such cases long ago. Per report from Magnus.
* Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).Tom Lane2007-02-27
| | | | | | | | | | | Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers. Greg Stark and Tom Lane

* I've created a new shared catalog table pg_shdescription to storeBruce Momjian2006-02-12
| | | | | | | | | | | | | | | | | | comments on cluster global objects like databases, tablespaces, and roles. It touches a lot of places, but not much in the way of big changes. The only design decision I made was to duplicate the query and manipulation functions rather than to try and have them handle both shared and local comments. I believe this is simpler for the code and not an issue for callers because they know what type of object they are dealing with. This has resulted in a shobj_description function analagous to obj_description and backend functions [Create/Delete]SharedComments mirroring the existing [Create/Delete]Comments functions. pg_shdescription.h goes into src/include/catalog/ Kris Jurka
* Fix the assert_enabled issue properly. This eliminates the former ABITom Lane2006-01-08
| | | | | difference between USE_ASSERT_CHECKING and not: the assert_enabled variable is always there.
* First phase of project to use fixed OIDs for all system catalogs andTom Lane2005-04-14
| | | | | | | | | | | | | | | | indexes. Extend the macros in include/catalog/*.h to carry the info about hand-assigned OIDs, and adjust the genbki script and bootstrap code to make the relations actually get those OIDs. Remove the small number of RelOid_pg_foo macros that we had in favor of a complete set named like the catname.h and indexing.h macros. Next phase will get rid of internal use of names for looking up catalogs and indexes; but this completes the changes forcing an initdb, so it looks like a good place to commit. Along the way, I made the shared relations (pg_database etc) not be 'bootstrap' relations any more, so as to reduce the number of hardwired entries and simplify changing those relations in future. I'm not sure whether they ever really needed to be handled as bootstrap relations, but it seems to work fine to not do so now.
* Tag appropriate files for rc3PostgreSQL Daemon2004-12-31
| | | | | | | | Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

* Tighten short-circuit tests for deciding whether we need to invokeTom Lane2004-01-16
| | | | | | | tuptoaster.c --- fields that are compressed in-line are not a reason to invoke the toaster. Along the way, add a couple more htup.h macros to eliminate confusing negated tests, and get rid of the already vestigial TUPLE_TOASTER_ACTIVE symbol.

* Make 'dummy' declarations in header files be 'extern int no_such_variable'Tom Lane2002-10-18
| | | | | instead of 'extern int errno'; the latter is unsafe according to the ANSI C standard, as well as in practice on some platforms.
* pgindent run.Bruce Momjian2002-09-04

* Clean up comments to be careful about the distinction between variable-Tom Lane2002-08-25
| | | | | | | | | | width types and varlena types, since with the introduction of CSTRING as a more-or-less-real type, these concepts aren't identical. I've tried to use varlena consistently to denote datatypes with typlen = -1, ie, they have a length word and are potentially TOASTable; while the term variable width covers both varlena and cstring (and, perhaps, someday other types with other rules for computing the actual width). No code changes in this commit except for renaming a couple macros.
* This patch removes a lot of unused code related to assertions andBruce Momjian2002-08-10
| | | | | | | | | | | | error handling, and simplifies the code that remains. Apparently, the code that left Berkeley had a whole "error handling subsystem", which exceptions and whatnot. Since we don't use that anymore, there's no reason to keep it around. The regression tests pass with the patch applied. Unless anyone sees a problem, please apply. Neil Conway

* Support toasting of shared system relations, and provide toast tables forTom Lane2002-04-27
| | | | | | | | | pg_database, pg_shadow, pg_group, all of which now have potentially-long fields. Along the way, get rid of SharedSystemRelationNames list: shared rels are now identified in their include/pg_catalog/*.h files by a BKI_SHARED_RELATION macro, while indexes and toast rels inherit sharedness automatically from their parent table. Fix some bugs with failure to detoast pg_group.grolist during ALTER GROUP.

* Ensure that all TransactionId comparisons are encapsulated in macrosTom Lane2001-08-23
| | | | | (TransactionIdPrecedes, TransactionIdFollows, etc). First step on the way to transaction ID wrap solution ...
* Make OIDs optional, per discussions in pghackers. WITH OIDS is still theTom Lane2001-08-10
| | | | | | | | | | | | default, but OIDS are removed from many system catalogs that don't need them. Some interesting side effects: TOAST pointers are 20 bytes not 32 now; pg_description has a three-column key instead of one. Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey has some usefulness; pg_dump dumps comments on indexes, rules, and triggers in a valid order. initdb forced.
* Clean up various to-do items associated with system indexes:Tom Lane2001-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg_database now has unique indexes on oid and on datname. pg_shadow now has unique indexes on usename and on usesysid. pg_am now has unique index on oid. pg_opclass now has unique index on oid. pg_amproc now has unique index on amid+amopclaid+amprocnum. Remove pg_rewrite's unnecessary index on oid, delete unused RULEOID syscache. Remove index on pg_listener and associated syscache for performance reasons (caching rows that are certain to change before you need 'em again is rather pointless). Change pg_attrdef's nonunique index on adrelid into a unique index on adrelid+adnum. Fix various incorrect settings of pg_class.relisshared, make that the primary reference point for whether a relation is shared or not. IsSharedSystemRelationName() is now only consulted to initialize relisshared during initial creation of tables and indexes. In theory we might now support shared user relations, though it's not clear how one would get entries for them into pg_class &etc of multiple databases. Fix recently reported bug that pg_attribute rows created for an index all have the same OID. (Proof that non-unique OID doesn't matter unless it's actually used to do lookups ;-)) There's no need to treat pg_trigger, pg_attrdef, pg_relcheck as bootstrap relations. Convert them into plain system catalogs without hardwired entries in pg_class and friends. Unify global.bki and template1.bki into a single init script postgres.bki, since the alleged distinction between them was misleading and pointless. Not to mention that it didn't work for setting up indexes on shared system relations. Rationalize locking of pg_shadow, pg_group, pg_attrdef (no need to use AccessExclusiveLock where ExclusiveLock or even RowExclusiveLock will do). Also, hold locks until transaction commit where necessary.
* Mark exception and assert global variables as DLLIMPORT, so that plpgsqlTom Lane2001-03-23
| | | | can be compiled with asserts enabled on Windoze.
* pgindent run. Make it all clean.Bruce Momjian2001-03-22

* Restructure the key include files per recent pghackers discussion: thereTom Lane2001-02-10
| | | | | | | | | | | are now separate files "postgres.h" and "postgres_fe.h", which are meant to be the primary include files for backend .c files and frontend .c files respectively. By default, only include files meant for frontend use are installed into the installation include directory. There is a new make target 'make install-all-headers' that adds the whole content of the src/include tree to the installed fileset, for use by people who want to develop server-side code without keeping the complete source tree on hand. Cleaned up a whole lot of crufty and inconsistent header inclusions.
