* Fix subtransaction behavior for large objects, temp namespace, files,Tom Lane2004-07-28
| | | | | | | password/group files. Also allow read-only subtransactions of a read-write parent, but not vice versa. These are the reasonably noncontroversial parts of Alvaro's recent mop-up patch, plus further work on large objects to minimize use of the TopTransactionResourceOwner.
* Reimplement the linked list data structure used throughout the backend.Neil Conway2004-05-26
| | | | | | | | | | | | | | | | In the past, we used a 'Lispy' linked list implementation: a "list" was merely a pointer to the head node of the list. The problem with that design is that it makes lappend() and length() linear time. This patch fixes that problem (and others) by maintaining a count of the list length and a pointer to the tail node along with each head node pointer. A "list" is now a pointer to a structure containing some meta-data about the list; the head and tail pointers in that structure refer to ListCell structures that maintain the actual linked list of nodes. The function names of the list API have also been changed to, I hope, be more logically consistent. By default, the old function names are still available; they will be disabled-by-default once the rest of the tree has been updated to use the new API names.

* Restructure smgr API as per recent proposal. smgr no longer depends onTom Lane2004-02-10
| | | | | | | | | the relcache, and so the notion of 'blind write' is gone. This should improve efficiency in bgwriter and background checkpoint processes. Internal restructuring in md.c to remove the not-very-useful array of MdfdVec objects --- might as well just use pointers. Also remove the long-dead 'persistent main memory' storage manager (mm.c), since it seems quite unlikely to ever get resurrected.

* Adjustments for Win32-specific rename code, and add include file.Bruce Momjian2004-02-02

* Adjust rename on Win32 to only link to temp name while holding lock,Bruce Momjian2004-02-02
| | | | then release locks and loop over renaming to active file name.
* Ensure that close() and fclose() are checked for errors, at least inTom Lane2004-01-26
| | | | | | cases involving writes. Per recent discussion about the possibility of close-time failures on some filesystems. There is a TODO item for this, too.
* More janitorial work: remove the explicit casting of NULL literals to aNeil Conway2004-01-07
| | | | | | | | pointer type when it is not necessary to do so. For future reference, casting NULL to a pointer type is only necessary when (a) invoking a function AND either (b) the function has no prototype OR (c) the function is a varargs function.

* Cross-data-type comparisons are now indexable by btrees, pursuant to myTom Lane2003-11-12
| | | | | | | | | | pghackers proposal of 8-Nov. All the existing cross-type comparison operators (int2/int4/int8 and float4/float8) have appropriate support. The original proposal of storing the right-hand-side datatype as part of the primary key for pg_amop and pg_amproc got modified a bit in the event; it is easier to store zero as the 'default' case and only store a nonzero when the operator is actually cross-type. Along the way, remove the long-since-defunct bigbox_ops operator class.
* Add operator strategy and comparison-value datatype fields to ScanKey.Tom Lane2003-11-09
| | | | | | | | | | | Remove the 'strategy map' code, which was a large amount of mechanism that no longer had any use except reverse-mapping from procedure OID to strategy number. Passing the strategy number to the index AM in the first place is simpler and faster. This is a preliminary step in planned support for cross-datatype index operations. I'm committing it now since the ScanKeyEntryInitialize() API change touches quite a lot of files, and I want to commit those changes before the tree drifts under me.

* First bits of work on error message editing.Tom Lane2003-07-18

* First batch of object rename commands.Peter Eisentraut2003-06-27
|
* Add binary I/O routines for a bunch more datatypes. Still a few to go,Tom Lane2003-05-12
| | | | | but that was enough tedium for one day. Along the way, move the few support routines for types xid and cid into a more logical place.
* Get rid of last few unadorned 'permission denied' messages.Tom Lane2003-01-27

* Make CREATE/ALTER/DROP USER/GROUP transaction-safe, or at least prettyTom Lane2002-10-21

* Translation updatesPeter Eisentraut2002-09-14

* pgindent run.Bruce Momjian2002-09-04

* Remove sys/types.h in files that include postgres.h, and hence c.h,Bruce Momjian2002-09-02
| | | | because c.h has sys/types.h.
* Group-manipulating code neglected to fill in array element type,Tom Lane2002-08-30
| | | | which is now required.
* 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.
* Restructure system-catalog index updating logic. Instead of havingTom Lane2002-08-05
| | | | | | | | | hardwired lists of index names for each catalog, use the relcache's mechanism for caching lists of OIDs of indexes of any table. This reduces the common case of updating system catalog indexes to a single line, makes it much easier to add a new system index (in fact, you can now do so on-the-fly if you want to), and as a nice side benefit improves performance a little. Per recent pghackers discussion.
* Remove unused system table columns:Peter Eisentraut2002-07-24

For pg_type, there is no warning (yet) because pg_dump scripts still contain these attributes. Also remove new but already obsolete spellings isVolatile, isStable, isImmutable in WITH clause. (Use new syntax instead.)

* Remove global variable scanCommandId in favor of storing a command IDTom Lane2002-05-21
| | | | | | | | | | | in snapshots, per my proposal of a few days ago. Also, tweak heapam.c routines (heap_insert, heap_update, heap_delete, heap_mark4update) to be passed the command ID to use, instead of doing GetCurrentCommandID. For catalog updates they'll still get passed current command ID, but for updates generated from the main executor they'll get passed the command ID saved in the snapshot the query is using. This should fix some corner cases associated with functions and triggers that advance current command ID while an outer query is still in progress.
* Restructure indexscan API (index_beginscan, index_getnext) perTom Lane2002-05-20
| | | | | | | yesterday's proposal to pghackers. Also remove unnecessary parameters to heap_beginscan, heap_rescan. I modified pg_proc.h to reflect the new numbers of parameters for the AM interface routines, but did not force an initdb because nothing actually looks at those fields.
* Merge the last few variable.c configuration variables into the genericTom Lane2002-05-17
| | | | | | | | | GUC support. It's now possible to set datestyle, timezone, and client_encoding from postgresql.conf and per-database or per-user settings. Also, implement rollback of SET commands that occur in a transaction that later fails. Create a SET LOCAL var = value syntax that sets the variable only for the duration of the current transaction. All per previous discussions in pghackers.

* 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.

| | | | | | | divide backend/commands by object type, let's try to pay at least minimal attention to respecting that structure, eh? Also reorder the contents of tablecmds.c; it seems odd to me to put ALTER commands before creation/deletion commands.

* Authentication improvements:Bruce Momjian2002-04-04
| | | | | | | | | | | | | | A new pg_hba.conf column, USER Allow specifiction of lists of users separated by commas Allow group names specified by + Allow include files containing lists of users specified by @ Allow lists of databases, and database files Allow samegroup in database column to match group name matching dbname Removal of secondary password files Remove pg_passwd utility Lots of code cleanup in user.c and hba.c New data/global/pg_pwd format New data/global/pg_group file
