Bruce Momjian	46785776c4	Another pgindent run with updated typedefs.	23 years ago
Bruce Momjian	f3c3deb7d0	Update copyrights to 2003.	23 years ago
Bruce Momjian	089003fb46	pgindent run.	23 years ago
Tom Lane	f85f43dfb5	Backend support for autocommit removed, per recent discussions. The ... only remnant of this failed experiment is that the server will take SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit logic in libpq.	23 years ago
Tom Lane	30f609484d	Add binary I/O routines for a bunch more datatypes. Still a few to go, ... 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.	23 years ago
Tom Lane	4db9689d1a	Add transaction status field to ReadyForQuery messages, and make room ... for tableID/columnID in RowDescription. (The latter isn't really implemented yet though --- the backend always sends zeroes, and libpq just throws away the data.)	23 years ago
Peter Eisentraut	b65cd56240	Read-only transactions, as defined in SQL.	23 years ago
Tom Lane	17ac74797a	Put back error test for DECLARE CURSOR outside a transaction block ... ... but do it correctly now.	23 years ago
Bruce Momjian	63e9734542	Update xact.c comments for clarity.	23 years ago
Tom Lane	200b151615	Fix places that were using IsTransactionBlock() as an (inadequate) check ... that they'd get to commit immediately on finishing. There's now a centralized routine PreventTransactionChain() that implements the necessary tests.	24 years ago
Tom Lane	26993b2918	AUTOCOMMIT mode is now an available backend GUC variable; setting it ... to false provides more SQL-spec-compliant behavior than we had before. I am not sure that setting it false is actually a good idea yet; there is a lot of client-side code that will probably be broken by turning autocommit off. But it's a start. Loosely based on a patch by David Van Wie.	24 years ago
Bruce Momjian	d84fe82230	Update copyright to 2002.	24 years ago
Tom Lane	959e61e917	Remove global variable scanCommandId in favor of storing a command ID ... 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.	24 years ago
Tom Lane	838fe25a95	Create a new GUC variable search_path to control the namespace search ... path. The default behavior if no per-user schemas are created is that all users share a 'public' namespace, thus providing behavior backwards compatible with 7.2 and earlier releases. Probably the semantics and default setting will need to be fine-tuned, but this is a start.	24 years ago
Bruce Momjian	ea08e6cd55	New pgindent run with fixes suggested by Tom. Patch manually reviewed, ... initdb/regression tests pass.	24 years ago
Bruce Momjian	6783b2372e	Another pgindent run. Fixes enum indenting, and improves #endif ... spacing. Also adds space for one-line comments.	25 years ago
Bruce Momjian	b81844b173	pgindent run on all C files. Java run to follow. initdb/regression ... tests pass.	25 years ago
Thomas G. Lockhart	9310075a13	Accept an INTERVAL argument for SET TIME ZONE per SQL99. ... Modified the parser and the SET handlers to use full Node structures rather than simply a character string argument. Implement INTERVAL() YEAR TO MONTH (etc) syntax per SQL99. Does not yet accept the goofy string format that goes along with, but this should be fairly straight forward to fix now as a bug or later as a feature. Implement precision for the INTERVAL() type. Use the typmod mechanism for both of INTERVAL features. Fix the INTERVAL syntax in the parser: opt_interval was in the wrong place. INTERVAL is now a reserved word, otherwise we get reduce/reduce errors. Implement an explicit date_part() function for TIMETZ. Should fix coersion problem with INTERVAL reported by Peter E. Fix up some error messages for date/time types. Use all caps for type names within message. Fix recently introduced side-effect bug disabling 'epoch' as a recognized field for date_part() etc. Reported by Peter E. (??) Bump catalog version number. Rename "microseconds" current transaction time field from ...Msec to ...Usec. Duh! date/time regression tests updated for reference platform, but a few changes will be necessary for others.	25 years ago
Thomas G. Lockhart	6f58115ddd	Measure the current transaction time to milliseconds. ... Define a new function, GetCurrentTransactionStartTimeUsec() to get the time to this precision. Allow now() and timestamp 'now' to use this higher precision result so we now have fractional seconds in this "constant". Add timestamp without time zone type. Move previous timestamp type to timestamp with time zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss (note the "T" separating the day from hours information). Remove 'current' from date/time types; convert to 'now' in input. Separate time and timetz regression tests. Separate timestamp and timestamptz regression test.	25 years ago
Tom Lane	bc7d37a525	Transaction IDs wrap around, per my proposal of 13-Aug-01. More ... documentation to come, but the code is all here. initdb forced.	25 years ago
Tom Lane	2589735da0	Replace implementation of pg_log as a relation accessed through the ... buffer manager with 'pg_clog', a specialized access method modeled on pg_xlog. This simplifies startup (don't need to play games to open pg_log; among other things, OverrideTransactionSystem goes away), should improve performance a little, and opens the door to recycling commit log space by removing no-longer-needed segments of the commit log. Actual recycling is not there yet, but I felt I should commit this part separately since it'd still be useful if we chose not to do transaction ID wraparound.	25 years ago
Tom Lane	b9f3a929ee	Create a new HeapTupleSatisfiesVacuum() routine in tqual.c that embodies the ... validity checking rules for VACUUM. Make some other rearrangements of the VACUUM code to allow more code to be shared between full and lazy VACUUM. Minor code cleanups and added comments for TransactionId manipulations.	25 years ago
Bruce Momjian	9e1552607a	pgindent run. Make it all clean.	25 years ago

Tom Lane	ad7b47aa02	Fix sloppy macro coding (not enough parentheses).	26 years ago
Bruce Momjian	20ad43b576	Mark functions as static and ifdef NOT_USED as appropriate.	26 years ago
Tom Lane	48165ec226	Latest round of fmgr updates. All functions with bool,char, or int2 ... inputs have been converted to newstyle. This should go a long way towards fixing our portability problems with platforms where char and short parameters are passed differently from int-width parameters. Still more to do for the Alpha port however.	26 years ago
