* We neglected to apply domain constraints on UNKNOWN parameters toNeil Conway2006-01-12
| | | | prepared statements, per report from David Wheeler.
* mbutils was previously doing some allocations, including invokingNeil Conway2006-01-12
| | | | | | | | | | fmgr_info(), in the TopMemoryContext. I couldn't see that the code actually leaked, but in general I think it's fragile to assume that pfree'ing an FmgrInfo along with its fn_extra field is enough to reclaim all the resources allocated by fmgr_info(). I changed the code to do its allocations in a new child context of TopMemoryContext, MbProcContext. When we want to release the allocations we can just reset the context, which is cleaner.
* Repair "Halloween problem" in EvalPlanQual: a tuple that's been inserted byTom Lane2006-01-12
| | | | | | | | our own command (or more generally, xmin = our xact and cmin >= current command ID) should not be seen as good. Else we may try to update rows we already updated. This error was inserted last August while fixing the even bigger problem that the old coding wouldn't see *any* tuples inserted by our own transaction as good. Per report from Euler Taveira de Oliveira.
* Create a standard function pg_sleep() to sleep for a specified amount of time.Tom Lane2006-01-11
| | | | | Replace the former ad-hoc implementation used in the regression tests. Joachim Wieland
* Cosmetic code cleanup: fix a bunch of places that used "return (expr);"Neil Conway2006-01-11
| | | | | | rather than "return expr;" -- the latter style is used in most of the tree. I kept the parentheses when they were necessary or useful because the return expression was complex.
* Remove a confusing pair of parentheses.Neil Conway2006-01-11

* Improve error messages for missing-FROM-entry cases, as per recent discussion.Tom Lane2006-01-10

* Improve patternsel() by applying the operator itself to each valueTom Lane2006-01-10
| | | | | | | | | listed in the column's most-common-values statistics entry. This gives us an exact selectivity result for the portion of the column population represented by the MCV list, which can be a big leg up in accuracy if that's a large fraction of the population. The heuristics involving pattern contents and prefix are applied only to the part of the population not included in the MCV list.
* Change allow_system_table_mods to PGC_POSTMASTER, restoring previousPeter Eisentraut2006-01-09
| | | | behavior.
* 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.
* Recent patch broke guc.c for non-USE_ASSERT_CHECKING case. PerTom Lane2006-01-08
| | | | Stefan Kaltenbrunner.
* Avoid leaking memory while reading toasted entries from pg_rewrite,Tom Lane2006-01-08
| | | | | | | and nail a couple more system indexes into cache. This doesn't make any difference in normal system operation, but when forcing constant cache resets it's difficult to get through the rules regression test without these changes.
* Add a new system view, pg_prepared_statements, that can be used toNeil Conway2006-01-08
| | | | | | | | | | | | | | | | access information about the prepared statements that are available in the current session. Original patch from Joachim Wieland, various improvements by Neil Conway. The "statement" column of the view contains the literal query string sent by the client, without any rewriting or pretty printing. This means that prepared statements created via SQL will be prefixed with "PREPARE ... AS ", whereas those prepared via the FE/BE protocol will not. That is unfortunate, but discussion on -patches did not yield an efficient way to improve this, and there is some merit in returning exactly what the client sent to the backend. Catalog version bumped, regression tests updated.
* Add RelationOpenSmgr() calls to ensure rd_smgr is valid when we try toTom Lane2006-01-07
| | | | | | use it. While it normally has been opened earlier during btree index build, testing shows that it's possible for the link to be closed again if an sinval reset occurs while the index is being built.
* Add comment explaining why RelationOpenSmgr() call is not needed.Tom Lane2006-01-07

* During CatCacheRemoveCList, we must now remove any members that areTom Lane2006-01-07
| | | | | | | | | dead and have become unreferenced. Before 8.1, such members were left for AtEOXact_CatCache() to clean up, but now AtEOXact_CatCache isn't supposed to have anything to do. In an assert-enabled build this bug leads to an assertion failure at transaction end, but in a non-assert build the dead member is effectively just a small memory leak. Per report from Jeremy Drake.
* Fix failure to apply domain constraints to a NULL constant that's added toTom Lane2006-01-06
| | | | an INSERT target list during rule rewriting. Per report from John Supplee.
* Fix Windows-only postmaster code to reject a connection request and continue,Tom Lane2006-01-06
| | | | | | | rather than elog(FATAL), when there is no more room in ShmemBackendArray. This is a security issue since too many connection requests arriving close together could cause the postmaster to shut down, resulting in denial of service. Reported by Yoshiyuki Asaba, fixed by Magnus Hagander.
* Convert Assert checking for empty page into a regular test and elog.Tom Lane2006-01-06
| | | | | The consequences of overwriting a non-empty page are bad enough that we should not omit this test in production builds.
* Fix ReadBuffer() to correctly handle the case where it's trying to extendTom Lane2006-01-06
| | | | | | | | | the relation but it finds a pre-existing valid buffer. The buffer does not correspond to any page known to the kernel, so we *must* do smgrextend to ensure that the space becomes allocated. The 7.x branches all do this correctly, but the corner case got lost somewhere during 8.0 bufmgr rewrites. (My fault no doubt :-( ... I think I assumed that such a buffer must be not-BM_VALID, which is not so.)
* Update x86 Solaris documenation ideas.Bruce Momjian2006-01-05

* Add compile flags sample.Bruce Momjian2006-01-05
|
* Make all command-line options of postmaster and postgres the same. SeePeter Eisentraut2006-01-05
| | | | | http://archives.postgresql.org/pgsql-hackers/2006-01/msg00151.php for the complete plan.
* Remove BEOS port.Bruce Momjian2006-01-05
|
* Remove QNX port.Bruce Momjian2006-01-05
|
* Rearrange backend startup sequence so that ShmemIndexLock can becomeTom Lane2006-01-04
| | | | | | an LWLock instead of a spinlock. This hardly matters on Unix machines but should improve startup performance on Windows (or any port using EXEC_BACKEND). Per previous discussion.
* Fix another case in which autovacuum would fail while analyzingTom Lane2006-01-04
| | | | expressional indexes. Per report from Brian Hirt.
* Assume select() might modify struct timeout, so remove previousBruce Momjian2006-01-03
| | | | optimization.
* Use setitimer() for stats file write, rather than do a gettimeofday()Bruce Momjian2006-01-03
| | | | | call for every stats packet read to adjust select() timeout. Other stylistic improvements.
* Don't assume that LC_MESSAGES is always available on WIN32. Per Magnus.Tom Lane2006-01-02

* Reset flex state in a way that works for both flex 2.5.4 and 2.5.31.Tom Lane2006-01-02
|
* Change if (!(x || y)) construct with if (!x && !y), for clarity.Bruce Momjian2006-01-02
|
* Rewrite ProcessConfigFile() to avoid misbehavior at EOF, as per reportTom Lane2006-01-01
| | | | | | | | from Andrus Moor. The former state-machine-style coding wasn't actually doing much except obscuring the control flow, and it didn't extend readily to fix this case, so I just took it out. Also, add a YY_FLUSH_BUFFER call to ensure the lexer is reset correctly if the previous scan failed partway through the file.
* Remove DOS line endings ("\r\n") from several .po files. DOS line endingsNeil Conway2006-01-01
| | | | | are inconsistent with the rest of the .po files, and apparently cause problems for Sun's cc. Per report on IRC from "bitvector2".
* Rename variable to cmd_str.Bruce Momjian2005-12-31
|
* Rename variable 'what' to 'stat_msg'.Bruce Momjian2005-12-31
|
* Prefix client-side prepare with '[protocol]' rather than '[client]'.Bruce Momjian2005-12-31
|
* Rename send_rfq to send_ready_for_query.Bruce Momjian2005-12-30
|
* Mmark client-side prepare/bind/execute statements with "[client]" soBruce Momjian2005-12-30
| | | | they can be easily distinguished from SQL commands.
* Add support for Solaris x86_64 using Sun's compiler.Bruce Momjian2005-12-30
| | | | Pierre Girard
* Repair EXPLAIN failure when trying to display a plan condition that involvesTom Lane2005-12-30
| | | | | | selection of a field from the result of a function returning RECORD. I believe this case is new in 8.1; it's due to the addition of OUT parameters. Per example from Michael Fuhr.
* Disallow setting ssl = on if SSL is not compiled in.Peter Eisentraut2005-12-30

* Get rid of the SpinLockAcquire/SpinLockAcquire_NoHoldoff distinctionTom Lane2005-12-29
| | | | | | | | | | in favor of having just one set of macros that don't do HOLD/RESUME_INTERRUPTS (hence, these correspond to the old SpinLockAcquire_NoHoldoff case). Given our coding rules for spinlock use, there is no reason to allow CHECK_FOR_INTERRUPTS to be done while holding a spinlock, and also there is no situation where ImmediateInterruptOK will be true while holding a spinlock. Therefore doing HOLD/RESUME_INTERRUPTS while taking/releasing a spinlock is just a waste of cycles. Qingqing Zhou and Tom Lane.
* Revert some careless search-and-replace: "ADD" in comment text shouldNeil Conway2005-12-29
| | | | not be replaced with "ADD_P".
* Arrange to set the LC_XXX environment variables to match our localeTom Lane2005-12-28
| | | | | | setup. This protects against undesired changes in locale behavior if someone carelessly does setlocale(LC_ALL, "") (and we know who you are, perl guys).
* Move plpgsql's fetchArgInfo() into funcapi.c, and rename toTom Lane2005-12-28
| | | | | | | | get_func_arg_info() for consistency with other names there. This code will probably be useful to other PLs when they start to support OUT parameters, so better to have it in the main backend. Also, fix plpgsql validator to detect bogus OUT parameters even when check_function_bodies is off.
* Mention "table" in "violates foreign key constraint" message that wasBruce Momjian2005-12-28
| | | | | lacking it. Perhaps it was suppressed because of line length considerations, but "table" should appear.
* Remove silly use of DLLIMPORT.Tom Lane2005-12-28
|
* Add regression tests for CSV and \., and add automatic quoting of aBruce Momjian2005-12-28
| | | | | single column dump that has a \. value, so the load works properly. I also added documentation describing this issue.
* Implement SQL-compliant treatment of row comparisons for < <= > >= casesTom Lane2005-12-28
| | | | | | | | | | | | | | | | (previously we only did = and <> correctly). Also, allow row comparisons with any operators that are in btree opclasses, not only those with these specific names. This gets rid of a whole lot of indefensible assumptions about the behavior of particular operators based on their names ... though it's still true that IN and NOT IN expand to "= ANY". The patch adds a RowCompareExpr expression node type, and makes some changes in the representation of ANY/ALL/ROWCOMPARE SubLinks so that they can share code with RowCompareExpr. I have not yet done anything about making RowCompareExpr an indexable operator, but will look at that soon. initdb forced due to changes in stored rules.
