* Regression tests for the COPY CSV header feature. From Andrew Dunstan.Neil Conway2005-05-10

* Update "expected" regression test output for the recent stats collectorNeil Conway2005-05-09
| | | | checkin. My apologies for breaking the tests.

* Add some defenses against functions declared to return set that don'tTom Lane2005-05-09

* Complete the following TODO items:Neil Conway2005-05-09
| | | | | | | | | * Add session start time to pg_stat_activity * Add the client IP address and port to pg_stat_activity Original patch from Magnus Hagander, code review by Neil Conway. Catalog version bumped. This patch sends the client IP address and port number in every statistics message; that's not ideal, but will be fixed up shortly.
* Update release checklist to reflect that HISTORY and INSTALL don'tTom Lane2005-05-08
| | | | need to be created by hand anymore.
* Repair very-low-probability race condition between relation extensionTom Lane2005-05-07
| | | | | | | | and VACUUM: in the interval between adding a new page to the relation and formatting it, it was possible for VACUUM to come along and decide it should format the page too. Though not harmful in itself, this would cause data loss if a third transaction were able to insert tuples into the vacuumed page before the original extender got control back.
* Adjust time qual checking code so that we always check TransactionIdIsInProgressTom Lane2005-05-07
| | | | | | | before we check commit/abort status. Formerly this was done in some paths but not all, with the result that a transaction might be considered committed for some purposes before it became committed for others. Per example found by Jan Wieck.
* Fix case in which a debug printout would print already-pfreed data.Tom Lane2005-05-07

* For some reason access/tupmacs.h has been #including utils/memutils.h,Tom Lane2005-05-06
| | | | | | | which is neither needed by nor related to that header. Remove the bogus inclusion and instead include the header in those C files that actually need it. Also fix unnecessary inclusions and bad inclusion order in tsearch2 files.
* Update comment to mention "Name classification hierarchy" as place toBruce Momjian2005-05-06
| | | | check for reserved words.
* Convert some mulit-line comments in copy.c to single line, as appropriate.Bruce Momjian2005-05-06
|
* Marginal performance improvements in dynahash: make sure that everythingTom Lane2005-05-06
| | | | | | associated with a hashtable is allocated in that hashtable's private context, so that hash_destroy only has to destroy the context and not do any retail pfree's; and tighten the inner loop of hash_seq_search.
* Fix bogus hashtable setup. (This code has quite a few other problemsTom Lane2005-05-05
| | | | too, but that one is in my way at the moment.)
* Make standalone backends ignore pg_database.datallowconn, so that thereTom Lane2005-05-05
| | | | is a way to recover from disabling connections to all databases at once.
* Add comments on WSAStartup usage.Bruce Momjian2005-05-05

* Add WSACleanup() for Win32 socket cleanup.Bruce Momjian2005-05-05
| | | | Jason Erickson
* Adjust nodeBitmapIndexscan to keep the target index opened from planTom Lane2005-05-05
| | | | | | | | | startup to end, rather than re-opening it in each MultiExecBitmapIndexScan call. I had foolishly thought that opening/closing wouldn't be much more expensive than a rescan call, but that was sheer brain fade. This seems to fix about half of the performance lossage reported by Sergey Koposov. I'm still not sure where the other half went.
* Allow implicit cast from any named composite type to RECORD. At theTom Lane2005-05-05
| | | | | | | moment this has no particular use except to allow table rows to be passed to record_out(), but that case seems to be useful in itself per recent example from Elein. Further down the road we could look at letting PL functions be declared to accept RECORD parameters.
* Use postmaster_is_alive() check in pg_ctl restart as well as pg_ctl status,Tom Lane2005-05-04
| | | | so that restart doesn't fail when old postmaster died unbetimes.
* Spell DELIMITER correctly, per Seamus Dean.Tom Lane2005-05-04
|
* Clean up MultiXactIdExpand's API by separating out the case where weTom Lane2005-05-03
| | | | | are creating a new MultiXactId from two regular XIDs. The original coding was unnecessarily complicated and didn't save any code anyway.
* Alter the signature for encoding conversion functions to declare theTom Lane2005-05-03
| | | | | | output area as INTERNAL not CSTRING. This is to prevent people from calling the functions by hand. This is a permanent solution for the back branches but I hope it is just a stopgap for HEAD.
* Change tsearch2 to not use the unsafe practice of creating functionsTom Lane2005-05-03
| | | | | | | | that return INTERNAL without also having INTERNAL arguments. Since the functions in question aren't meant to be called by hand anyway, I just redeclared them to take 'internal' instead of 'text'. Also add code to ProcedureCreate() to enforce the restriction, as I should have done to start with :-(
* Check the file system on postmaster startup and report any unreferencedBruce Momjian2005-05-02
| | | | | | files in the server log. Heikki Linnakangas
* Change SPI functions to use a `long' when specifying the number of tuplesNeil Conway2005-05-02
| | | | | | | | to produce when running the executor. This is consistent with the internal executor APIs (such as ExecutorRun), which also use a long for this purpose. It also allows FETCH_ALL to be passed -- since FETCH_ALL is defined as LONG_MAX, this wouldn't have worked on platforms where int and long are of different sizes. Per report from Tzahi Fadida.
* Change CREATE TYPE to require datatype output and send functions to haveTom Lane2005-05-01
| | | | | | | only one argument. (Per recent discussion, the option to accept multiple arguments is pretty useless for user-defined types, and would be a likely source of security holes if it was used.) Simplify call sites of output/send functions to not bother passing more than one argument.
* Remove the contents of the src/corba subdirectory: this has been dead codeNeil Conway2005-05-01
| | | | for a long time.
* Change catalog entries for record_out and record_send to show only oneTom Lane2005-04-30
| | | | | | argument, since that's all they are using now. Adjust type_sanity regression test so that it will complain if anyone tries to define multiple-argument output functions in future.
* Make record_out and record_send extract type information from the passedTom Lane2005-04-30
| | | | | | | record object itself, rather than relying on a second OID argument to be correct. This patch just changes the function behavior and not the catalogs, so it's OK to back-patch to 8.0. Will remove the now-redundant second argument in pg_proc in a separate patch in HEAD only.
* Use the standard lock manager to establish priority order when thereTom Lane2005-04-30
| | | | | | is contention for a tuple-level lock. This solves the problem of a would-be exclusive locker being starved out by an indefinite succession of share-lockers. Per recent discussion with Alvaro.
* GCC 4.0 includes a new warning option, -Wformat-literal, that emitsNeil Conway2005-04-30
| | | | | | | | | | | | | | | a warning when a variable is used as a format string for printf() and similar functions (if the variable is derived from untrusted data, it could include unexpected formatting sequences). This emits too many warnings to be enabled by default, but it does flag a few dubious constructs in the Postgres tree. This patch fixes up the obvious variants: functions that are passed a variable format string but no additional arguments. Most of these are harmless (e.g. the ruleutils stuff), but there is at least one actual bug here: if you create a trigger named "%sfoo", pg_dump will read uninitialized memory and fail to dump the trigger correctly.
* Fix BCC to not define compiler location.Bruce Momjian2005-04-30

* Restructure LOCKTAG as per discussions of a couple months ago.Tom Lane2005-04-29
| | | | | | | | | | | | | | Essentially, we shoehorn in a lockable-object-type field by taking a byte away from the lockmethodid, which can surely fit in one byte instead of two. This allows less artificial definitions of all the other fields of LOCKTAG; we can get rid of the special pg_xactlock pseudo-relation, and also support locks on individual tuples and general database objects (including shared objects). None of those possibilities are actually exploited just yet, however. I removed pg_xactlock from pg_class, but did not force initdb for that change. At this point, relkind 's' (SPECIAL) is unused and could be removed entirely.
* Remove extern from optreset that was just added.Bruce Momjian2005-04-29

* Improve cleanup from win32 client-only build.Bruce Momjian2005-04-29

* Backpatch BCC compile changes to 8.0.X for psql.Bruce Momjian2005-04-29
|
* This patch fixes a bug in the error message emitted by pg_restore on anNeil Conway2005-04-29
| | | | | incorrect -F argument: write_msg() expects its first parameter to be a "module name", not the format string.
* Implement sharable row-level locks, and use them for foreign key referencesTom Lane2005-04-28
| | | | | | | | | | | | | | | to eliminate unnecessary deadlocks. This commit adds SELECT ... FOR SHARE paralleling SELECT ... FOR UPDATE. The implementation uses a new SLRU data structure (managed much like pg_subtrans) to represent multiple- transaction-ID sets. When more than one transaction is holding a shared lock on a particular row, we create a MultiXactId representing that set of transactions and store its ID in the row's XMAX. This scheme allows an effectively unlimited number of row locks, just as we did before, while not costing any extra overhead except when a shared lock actually has to be shared. Still TODO: use the regular lock manager to control the grant order when multiple backends are waiting for a row lock. Alvaro Herrera and Tom Lane.
* Fix a whitespace problem. From Alvaro Herrera.Dennis Bjorklund2005-04-28
|
* Add psql \set ON_ERROR_ROLLBACK to allow statements in a transaction toBruce Momjian2005-04-28
| | | | | error without affecting the entire transaction. Valid values are "on|interactive|off".
* On further experimentation, there were still a couple of bugs inTom Lane2005-04-25
| | | | ExpandIndirectionStar() ... and in markTargetListOrigin() too.
* Fix ExpandIndirectionStar to handle cases where the expression to beTom Lane2005-04-25
| | | | | | expanded is of RECORD type, eg 'select (foo).* from (select foo(f1) from t1) ss' where foo() is a function declared with multiple OUT parameters.
* get_expr_result_type probably needs to be able to handle OpExpr as wellTom Lane2005-04-25
| | | | | as FuncExpr, to cover cases where a function returning tuple is invoked via an operator.
