2000-12-23Improve comments.Tom Lane
2000-12-23Compute reasonable cost and output-row-count estimates for LIMIT planTom Lane
nodes.
2000-12-23Replace overly-cute coding with code that (a) has defined behaviorTom Lane
according to the ANSI C spec, (b) gets the boundary conditions right, and (c) is about a third as long and three times more intelligible.
2000-12-22Small cleanup of temp-table handling. Disallow creation of a non-tempTom Lane
table that inherits from a temp table. Make sure the right things happen if one creates a temp table, creates another temp that inherits from it, then renames the first one. (Previously, system would end up trying to delete the temp tables in the wrong order.)
2000-12-22Repair not-too-well-thought-out code to do rangechecking of OIDs onTom Lane
64-bit machines. Also, make oidvectorin use the same code as oidin.
2000-12-22Avoid XLogFlush for clean buffers in BufferSync.Vadim B. Mikheev
2000-12-22Improve error message for case where DROP TABLE is rejected becauseTom Lane
table has a child table.
2000-12-22Add 'ONLY' to queries generated by RI triggers, so as to preserve pre-7.1Tom Lane
semantics of RI operations. Eventually we ought to look at making RI work properly across inheritance trees, but not for 7.1 ...
2000-12-22Change default output formatting for CIDR to be unabbreviated, perTom Lane
recommendation from Paul Vixie. Add a new abbrev() function to produce abbreviated format as text. No forced initdb, but new function is not available unless you do an initdb or add the pg_proc row manually.
2000-12-22- Fixed bug in a connect statement using varchars.Michael Meskes
- Synced parser.
2000-12-22Fix PQsetdbLogin() backward compatibility problem.Tatsuo Ishii
If pghost == "" and pgport == "" then PQsetdbLogin() fails with a error message: Is the postmaster running locally and accepting connections on Unix socket '/tmp/.s.PGSQL.0'? I see many applications such as PHP fails due to this behavior. Now if pgport == "", then it is assumed to be a DEF_PGPORT_STR. This is the same behavior as the version prior 7.1.
2000-12-22Clean up CREATE TYPE/OPERATOR/AGGREGATE productions, so that parserTom Lane
will not accept types named with operator names or vice versa.
2000-12-22In looking at the 7.1beta1 code for JDBC, I noticed that support wasBruce Momjian
added to support character set encodings. However I noticed that the encoding that is used isn't obtained from the DB. Since Java uses unicode UCS2 internally the character set encoding is used to translate strings from/to the DB encoding. So it seems logical that the code would get the encoding from the DB instead of the current method of requiring the user pass it as a parameter. Attached is a patch that gets the DB encoding from the DB in the same manner as is done in libpq/fe-connect.c. The patch is created off of the latest CVS sources (Connection.java version 1.10).

2000-12-22Revise lock manager to support "session level" locks as well as "transactionTom Lane
level" locks. A session lock is not released at transaction commit (but it is released on transaction abort, to ensure recovery after an elog(ERROR)). In VACUUM, use a session lock to protect the master table while vacuuming a TOAST table, so that the TOAST table can be done in an independent transaction. I also took this opportunity to do some cleanup and renaming in the lock code. The previously noted bug in ProcLockWakeup, that it couldn't wake up any waiters beyond the first non-wakeable waiter, is now fixed. Also found a previously unknown bug of the same kind (failure to scan all members of a lock queue in some cases) in DeadLockCheck. This might have led to failure to detect a deadlock condition, resulting in indefinite waits, but it's difficult to characterize the conditions required to trigger a failure.
2000-12-21Repair round(numeric) function. An initdb would be required to get thePeter Eisentraut
fixed version, otherwise you'll continue to encounter breakage.
2000-12-21Fix longstanding bug with VIEW using BETWEEN: OffsetVarNodes would getTom Lane
applied to the duplicated subtree twice. Probably someday we should fix the parser not to generate multiple links to the same subtree, but for now a quick copyObject() is the path of least resistance.
2000-12-20Remove multi.c and single.c, which have been dead code forTom Lane
over two years.
2000-12-20Prevent freshly-started backend from ignoring SIGUSR1, per race conditionTom Lane
observed by Inoue. Also, don't call ProcRemove() from postmaster if we have detected a backend crash --- too risky if shared memory is corrupted. It's not needed anyway, considering we are going to reinitialize shared memory and semaphores as soon as the last child is dead.
2000-12-20Finished build.xml and updated Driver.java.in and buildDriver to match how ↵Peter Mount
Makefile and ANT operate.
2000-12-19Rename --accounts-only to --globals-only, polish documentation.Peter Eisentraut
2000-12-19Polish PL/Perl documentation. The README file got shrunk to being aPeter Eisentraut
pointer into the real documentation.
2000-12-19Remove inclusions of <malloc.h>.Peter Eisentraut
2000-12-19Finally created ant build.xml filePeter Mount

2000-12-18Ensure that 'errno' is saved and restored by all signal handlers thatTom Lane
might change it. Experimentation shows that the signal handler call mechanism does not save/restore errno for you, at least not on Linux or HPUX, so this is definitely a real risk.
2000-12-18Updates for 7.1 branding.Bruce Momjian
2000-12-18 - Synced gram.y and preproc.y.Michael Meskes
- Synced keyword.c. - Added several small patches from Christof.
2000-12-18Make sure make_rels_by_clause_joins doesn't return multiple referencesTom Lane
to same joinrel. Although make_rels_by_joins doesn't mind, GEQO has an Assert that doesn't like this.
2000-12-18Tweak regressplans.sh to use any already-set PGOPTIONS.Tom Lane
2000-12-18Repair mishandling of PRIMARY KEY declaration that references anTom Lane
inherited column, per bug report from Elphick 12/15/00.
2000-12-18Clean up backend-exit-time cleanup behavior. Use on_shmem_exit callbacksTom Lane
to ensure that we have released buffer refcounts and so forth, rather than putting ad-hoc operations before (some of the calls to) proc_exit. Add commentary to discourage future hackers from repeating that mistake.
2000-12-17Tweak select_common_type() to deal with possibility of multiple preferredTom Lane
types in a category --- it was taking the last preferred type among the inputs, rather than the first one as intended.
2000-12-16Fix linker options for ODBC driver. See comment inPeter Eisentraut
src/interfaces/odbc/GNUmakefile.
2000-12-16Fix rules to re-generate config.h. The examples in the Autoconf manual arePeter Eisentraut
flawed because the timestamp file is already updated when Makefile.global is remade, and the rule for config.h never gets run.
2000-12-15Remove current->old mapping.Bruce Momjian
2000-12-15Change ET_WARN to ET_NOTICE to match internal codes, leave message asBruce Momjian
WARNING. Fix German FAQ mention about warning.
2000-12-15Make algorithm for resolving UNKNOWN function/operator inputs beTom Lane
insensitive to the order of arguments. Per pghackers discussion 12/10/00.
2000-12-15here is a patch fixing today's bug report:Bruce Momjian
> Date: Thu, 14 Dec 2000 12:44:47 +0100 (CET) > From: Kovacs Zoltan Sandor <tip@pc10.radnoti-szeged.sulinet.hu> > To: pgsql-bugs@postgresql.org > Subject: [BUGS] to_char() causes backend to close connection > > Hi, this query gives different strange results: > > select to_char(now()::abstime,'YYMMDDHH24MI'); > > I get e.g. a "backend closed the channel unexpectedly..." error with > successful or failed resetting attempt (indeterministic) Again thanks Kovacs, you found really designing bug, that appear if anyone write bad format template to "number" version of to_char() (as you with 'DD'). Karel
2000-12-15there is one problem with Zoltan patches commited into the tree:Bruce Momjian
if we set autocommit off and issued COMMIT (or ROLLBACK) on a connection new transaction is not started Max Khon
2000-12-15List .o file explicitly as dependency, to work around a gmake bugPeter Eisentraut
(intermediate .o file gets deleted and rebuild on next make invocation).
2000-12-15Remove obsolete comment.Tom Lane
2000-12-15Print the error message before attempting to reset the connection after aPeter Eisentraut
backend crash.
2000-12-15Remove a few remaining vestiges of elog(WARN).Tom Lane
2000-12-14BugfixJan Wieck
Trying to connect to template0 left a global referenced buffer because the scan of pg_database wasn't ended properly before elog(FATAL). Jan
2000-12-14Planner speedup hacking. Avoid saving useless pathkeys, so that pathTom Lane
comparison does not consider paths different when they differ only in uninteresting aspects of sort order. (We had a special case of this consideration for indexscans already, but generalize it to apply to ordered join paths too.) Be stricter about what is a canonical pathkey to allow faster pathkey comparison. Cache canonical pathkeys and dispersion stats for left and right sides of a RestrictInfo's clause, to avoid repeated computation. Total speedup will depend on number of tables in a query, but I see about 4x speedup of planning phase for a sample seven-table query.
2000-12-14Make sure to not handle deactivated system indexesHiroshi Inoue
2000-12-14Change StoreCatalogInheritance() to work from a list of parent relationTom Lane
OIDs rather than names. Aside from being simpler and faster, this way doesn't blow up in the face of 'create temp table foo () inherits (foo)'. Which is a rather odd thing to do, but it seems some people want to.
2000-12-13Fix thinko for case of outer join where inner table is empty: shouldTom Lane
output first outer tuple before advancing...
2000-12-12Cache eval cost of qualification expressions in RestrictInfo nodes toTom Lane
avoid repeated evaluations in cost_qual_eval(). This turns out to save a useful fraction of planning time. No change to external representation of RestrictInfo --- although that node type doesn't appear in stored rules anyway.
2000-12-11Remove elog for online log files.Vadim B. Mikheev
