* Revert ill-conceived change of libpq linkage --- breaks ecpg.Tom Lane2005-03-24
|
* array_map can't use the fn_extra field of the provided fcinfo struct asTom Lane2005-03-24
| | | | | its private storage, because that belongs to the function that it is supposed to call. Per report from Ezequiel Tolnay.
* Force PG client applications to link to non-shared libpgport beforeBruce Momjian2005-03-24
| | | | | | | linking to libpq. This insulates applications from changes in libpq's usage of libpgport functions. Backpatched to 8.0.X.
* Tweak planner to use a minimum size estimate of 10 pages for aTom Lane2005-03-24
| | | | | | | | never-yet-vacuumed relation. This restores the pre-8.0 behavior of avoiding seqscans during initial data loading, while still allowing reasonable optimization after a table has been vacuumed. Several regression test cases revert to 7.4-like behavior, which is probably a good sign. Per gripes from Keith Browne and others.
* Fix python regression testing script to bail out early if languageTom Lane2005-03-24
| | | | creation fails ... no point in running the tests.
* Adjust plpython to convert \r\n and \r to \n in Python scripts,Tom Lane2005-03-24
| | | | | per recent discussion concluding that this is the Right Thing. Add regression test check for this behavior. Michael Fuhr
* Change Win32 O_SYNC method to O_DSYNC because that is what the methodBruce Momjian2005-03-24
| | | | | | | | | | | currently does. This is now the default Win32 wal sync method because we perfer o_datasync to fsync. Also, change Win32 fsync to a new wal sync method called fsync_writethrough because that is the behavior of _commit, which is what is used for fsync on Win32. Backpatch to 8.0.X.
* Add missing error checking in readdir() loops.Tom Lane2005-03-24

* WAL must log CREATE and DROP DATABASE operations *without* using anyTom Lane2005-03-23
| | | | | | | | | | | explicit paths, so that the log can be replayed in a data directory with a different absolute path than the original had. To avoid forcing initdb in the 8.0 branch, continue to accept the old WAL log record types; they will never again be generated however, and the code can be dropped after the next forced initdb. Per report from Oleg Bartunov. We still need to think about what it really means to WAL-log CREATE TABLESPACE commands: we more or less have to put the absolute path into those, but how to replay in a different context??
* Fix quote_ident to use quote_identifier rather than its own, not quiteTom Lane2005-03-21
| | | | | | up-to-speed logic; in particular this will cause it to quote names that match keywords. Remove unnecessary multibyte cruft from quote_literal (all backend-internal encodings are 8-bit-safe).
* Put 'dump complete' message in the right place, so it comes out whereTom Lane2005-03-18
| | | | it's supposed to when --file option is used.
* Need to reset local buffer pin counts, not only shared buffer pins,Tom Lane2005-03-18
| | | | before we attempt any file deletions in ShutdownPostgres. Per Tatsuo.
* Added patch by Christof Petig <christof@petig-baender.de> to work around gcc ↵Michael Meskes2005-03-18
| | | | bug on powerpc and amd64.
* Need to release buffer pins before attempting to drop files duringTom Lane2005-03-18
| | | | backend exit. Per report from Bruce.
* Treat EPERM as a non-error case when checking to see if old postmasterTom Lane2005-03-18
| | | | | | | | | is still alive. This improves our odds of not getting fooled by an unrelated process when checking a stale lock file. Other checks already in place, plus one newly added in checkDataDir(), ensure that we cannot attempt to usurp the place of a postmaster belonging to a different userid, so there is no need to error out. Add comments indicating the importance of these other checks.
* Backpatch to 8.0.X, already in HEAD:Bruce Momjian2005-03-17
| | | | | Allow Win32 to support the O_SYNC open flag as an wal_sync_method method.
* Add missing include for new lc_ctype_is_c() function.Bruce Momjian2005-03-16
| | | | Per Neil.
* Prevent locale-aware handling of upper, lower, and initcap when theBruce Momjian2005-03-16
| | | | | | | locale is C. Backpatch to 8.0.X because some operating systems were throwing errors for such operations, rather than ignoring the locale when it was C.
* Increment all major version numbers in 8.0.X to force recompile ofBruce Momjian2005-03-13
| | | | | client aplications so 7.4.X releases can be installed on the same machine as 8.0.X.
* Fix ALTER DATABASE RENAME to allow the operation if user is a superuserTom Lane2005-03-12
| | | | | who for some reason isn't marked usecreatedb. Per report from Alexander Pravking. Also fix sloppy coding in have_createdb_privilege().
* Fix problem with infinite recursion between write_syslogger_file andTom Lane2005-03-12
| | | | | | | | elog if the former has trouble writing its file. Code review for Magnus' patch to redirect stderr to syslog on Windows (Bruce's version seems right, but did some minor prettification). Backpatch both changes to 8.0 branch.
* Properly implement "Response files" for bcc. Add URL's to describe theBruce Momjian2005-03-07
| | | | feature for Win32 and bcc.
* Replace ARC cache management algorithm with the similar but slightlyTom Lane2005-03-03
| | | | | | | | | simpler 2Q algorithm, to avoid possible problems with the pending patent on ARC. Testing so far suggests that there is little if any performance loss from doing this. Note that this patch is going into the 8.0 branch only; a much more extensive revision is planned for HEAD.
* Release proclock immediately in RemoveFromWaitQueue() if it representsTom Lane2005-03-01
| | | | | | no held locks. This maintains the invariant that proclocks are present only for procs that are holding or awaiting a lock; when this is not true, LockRelease will fail. Per report from Stephen Clouse.
* Adjust OR indexscan logic to not generate redundant condition-free ORTom Lane2005-03-01
| | | | | | indexscans involving partial indexes. These would always be dominated by a simple indexscan on such an index, so there's no point in considering them. Fixes overoptimism in a patch I applied last October.
* Revert the logic for expanding AND/OR conditions in pred_test() to whatTom Lane2005-03-01
| | | | | | it was in 7.4, and add some comments explaining why it has to be this way. I broke it for OR'd index predicates in a fit of code cleanup last summer. Per example from Sergey Koshcheyev.
* Tab indent all actions in bcc32.mak, and do it on win32.mak too forBruce Momjian2005-02-27
| | | | consistency. Backpatch only bcc32.mak to 8.0.X.
* Add linking from /port to bcc makefile.Bruce Momjian2005-02-25
|
* Try to get Borland CC to compile.Bruce Momjian2005-02-21
| | | | Backpatch to 8.0.X which doesn't work right now.
* New arrangement to always let the bgwriter do checkpoints brokeTom Lane2005-02-19
| | | | | CHECKPOINT and some other commands in the context of a standalone backend. Allow a standalone backend to do its own checkpoints.
* Ensure that the resolved datatype of any unknown Param is propagatedTom Lane2005-02-19
| | | | | into the sub-SELECT targetlist when it appears in the context INSERT INTO foo SELECT $1 ... Per report from Abhijit Menon-Sen.
* ALTER LANGUAGE RENAME has never worked. Per Sergey Yatskevich.Tom Lane2005-02-14

* Print file name and errno string on rmtree failure.Bruce Momjian2005-02-13
| | | | Backpatch to 8.0.X.
* Translation updatesPeter Eisentraut2005-02-11
|
* Fix SPI cursor support to allow scanning the results of utility commandsTom Lane2005-02-10
| | | | | | that return tuples (such as EXPLAIN). Per gripe from Michael Fuhr. Side effect: fix an old bug that unintentionally disabled backward scans for all SPI-created cursors.
* Fixed more parsing bugs in other CREATE statements.Michael Meskes2005-02-10

* ALTER TABLE ADD COLUMN exhibits a significant memory leak when adding aNeil Conway2005-02-09
| | | | | | | | | | | | | | | | | | | | column with a default expression. In that situation, we need to rewrite the heap relation. To evaluate the new default expression, we use ExecEvalExpr(); however, this can allocate memory in the current memory context, and ATRewriteTable() does not switch out of the active portal's heap memory context. The end result is a rather large memory leak (on the order of gigabytes for a reasonably sized table). This patch changes ATRewriteTable() to switch to the per-tuple memory context before beginning the per-tuple loop. It also removes an explicit heap_freetuple() in the loop, since that is no longer needed. In an unrelated change, I noticed the code was scanning through the attributes of the new tuple descriptor for each tuple of the old table. I changed this to use precomputation, which should slightly speed up the loop. Thanks to steve@deefs.net for reporting the leak.
* Fixed bug in parsing of CREATE AS statement.Michael Meskes2005-02-09

* If we're gonna check for array overrun, we really should do so beforeTom Lane2005-02-08
| | | | overrunning the array, not after.
* Prevent 4 more buffer overruns in the PL/PgSQL parser. This is just aNeil Conway2005-02-07
| | | | | minimally-invasive fix for stable branches; a cleaner fix will be committed to HEAD soon.
* Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns outTom Lane2005-02-06
| | | | | | | there are corner cases involving dropping toasted columns in which the previous coding would fail, too: the new version of the table might not have any TOAST table, but we'd still propagate possibly-wide values of dropped columns forward.
* Fix minor thinko in logic to set dump order when dumping from a pre-7.3Tom Lane2005-02-03
| | | | | database: aggregates should be dumped in the same pass as operators, not in the same pass as functions.
* Ensure that all details of the ARC algorithm are hidden within freelist.c.Tom Lane2005-02-03
| | | | | This refactoring does not change any algorithms or data structures, just remove visibility of the ARC datastructures from other source files.
* Improve performance of fmgr.c calling routines for cases with more thanTom Lane2005-02-02
| | | | two arguments. Per suggestions from A. Ogawa.
* Adjust constant-folding of CASE expressions so that the simple comparisonTom Lane2005-02-02
| | | | | | | | form of CASE (eg, CASE 0 WHEN 1 THEN ...) can be constant-folded as it was in 7.4. Also, avoid constant-folding result expressions that are certainly unreachable --- the former coding was a bit cavalier about this and could generate unexpected results for all-constant CASE expressions. Add regression test cases. Per report from Vlad Marchenko.
* Fix a bug induced by the list-rewrite that resulted in incrementing theNeil Conway2005-02-01
| | | | command counter more than necessary. Per report from Michael Fuhr.
* Adjust estimate_num_groups() to not clamp per-relation group countTom Lane2005-02-01
| | | | | | | estimate to less than the number of values estimated for any one grouping Var, as suggested by Manfred. This is intuitively right, and what's more it puts the plan choices in the subselect regression test back the way they were before ...
* Adjust plpgsql to allow assignment to an element of an array that isTom Lane2005-02-01
| | | | | | initially NULL. For 8.0 we changed the main executor to have this behavior in an UPDATE of an array column, but plpgsql's equivalent case was overlooked. Per report from Sven Willenberger.
* Sync inet formatting code with recent BIND releases. In particular,Tom Lane2005-02-01
| | | | | fix bug with inconsistent selection of default mask length for "class D" addresses. Per report from Steve Atkins.
* Stamp 8.0 branch as 8.0.1.Tom Lane2005-01-30
