* Put #ifdef NOT_USED around posix_fadvise call. We may want to resurrectTom Lane2006-06-27
| | | | | | this someday, but right now it seems that posix_fadvise is immature to the point of being broken on many platforms ... and we don't have any benchmark evidence proving it's worth spending time on.

* Extend the MinimalTuple concept to tuplesort.c, thereby reducing theTom Lane2006-06-27
| | | | | | | | | per-tuple space overhead for sorts in memory. I chose to replace the previous patch that tried to write out the bare minimum amount of data when sorting on disk; instead, just dump the MinimalTuples as-is. This wastes 3 to 10 bytes per tuple depending on architecture and null-bitmap length, but the simplification in the writetup/readtup routines seems worth it.

* Create infrastructure for 'MinimalTuple' representation of in-memoryTom Lane2006-06-27
| | | | | | | | tuples with less header overhead than a regular HeapTuple, per my recent proposal. Teach TupleTableSlot code how to deal with these. As proof of concept, change tuplestore.c to store MinimalTuples instead of HeapTuples. Future patches will expand the concept to other places where it is useful.

* Change the row constructor syntax (ROW(...)) so that list elements foo.*Tom Lane2006-06-26
| | | | | | | | | | will be expanded to a list of their member fields, rather than creating a nested rowtype field as formerly. (The old behavior is still available by omitting '.*'.) This syntax is not allowed by the SQL spec AFAICS, so changing its behavior doesn't violate the spec. The new behavior is substantially more useful since it allows, for example, triggers to check for data changes with 'if row(new.*) is distinct from row(old.*)'. Per my recent proposal.

* Tweak dynahash.c to avoid wasting memory space in non-shared hash tables.Tom Lane2006-06-25
| | | | | | | | palloc() will normally round allocation requests up to the next power of 2, so make dynahash choose allocation sizes that are as close to a power of 2 as possible. Back-patch to 8.1 --- the problem exists further back, but a much larger patch would be needed and it doesn't seem worth taking any risks.

* Our version of getopt_long does not set optarg upon detecting an error, asAlvaro Herrera2006-06-25

* Fix Win32/Cygwin problems:Bruce Momjian2006-06-25
| | | | | | | | | | | | | | After updating to the latest cvs, and also building most of the addons (like PLs), the following patch is neededf for win32 + Visual C++. * Switch to use the new win32 semaphore code * Rename win32_open to pgwin32_open. win32_open collides with symbols defined in Perl. MingW didn't detect ig, MSVC did. And it's a bit too generic a name to export globally, imho... * Python defines some partially broken #pragmas in the headers when doing a debug build. Workaround.

* Move setup_cancel_handler() up near start of psql main(), where theTom Lane2006-06-21
| | | | | setup_win32_locks() call formerly was, to ensure that cancelConnLock is valid when it needs to be. Per Yoshiyuki Asaba.
* Remove ancient kluge that kept nodeAgg.c from crashing on UPDATEs involvingTom Lane2006-06-21
| | | | | | aggregates. We just disallowed that, and AFAICS there should be no other cases where direct (non-aggregated) references to input columns are allowed in a query with aggregation and no GROUP BY.
* Disallow aggregate functions in UPDATE commands (unless within a sub-SELECT).Tom Lane2006-06-21
| | | | | | | | This is disallowed by the SQL spec because it doesn't have any very sensible interpretation. Historically Postgres has allowed it but behaved strangely. As of PG 8.1 a server crash is possible if the MIN/MAX index optimization gets applied; rather than try to "fix" that, it seems best to just enforce the spec restriction. Per report from Josh Drake and Alvaro Herrera.
* Eliminate a gratuitously different wording of the 'cannot use aggregate ↵Tom Lane2006-06-21
| | | | function in check constraint' error message.
* Clean up psql variable code a little: eliminate unnecessary tests inTom Lane2006-06-21
| | | | | | | GetVariable() and be consistent about treatment of the list header. Motivated by noticing strspn() taking an unreasonable percentage of runtime --- the call removed from GetVariable() was the only one that could be in a high-usage path ...

* Remove redundant gettimeofday() calls to the extent practical withoutTom Lane2006-06-20
| | | | | | | | | | | changing semantics too much. statement_timestamp is now set immediately upon receipt of a client command message, and the various places that used to do their own gettimeofday() calls to mark command startup are referenced to that instead. I have also made stats_command_string use that same value for pg_stat_activity.query_start for both the command itself and its eventual replacement by <IDLE> or <idle in transaction>. There was some debate about that, but no argument that seemed convincing enough to justify an extra gettimeofday() call.
* Split definitions for md5.c out of crypt.h and into their own headerTom Lane2006-06-20
| | | | | | | | | libpq/md5.h, so that there's a clear separation between backend-only definitions and shared frontend/backend definitions. (Turns out this is reversing a bad decision from some years ago...) Fix up references to crypt.h as needed. I looked into moving the code into src/port, but the headers in src/include/libpq are sufficiently intertwined that it seems more work than it's worth to do that.
* Do not use already free'ed errmsg, bug found by Joachim WielandMichael Meskes2006-06-19
| | | | <joachim.wieland@credativ.de>
* Take the statistics collector out of the loop for monitoring backends'Tom Lane2006-06-19
| | | | | | | current commands; instead, store current-status information in shared memory. This substantially reduces the overhead of stats_command_string and also ensures that pg_stat_activity is fully up to date at all times. Per my recent proposal.
* Don't try to call posix_fadvise() unless <fcntl.h> supplies a declarationTom Lane2006-06-18
| | | | | | | | for it. Hopefully will fix core dump evidenced by some buildfarm members since fadvise patch went in. The actual definition of the function is not ABI-compatible with compiler's default assumption in the absence of any declaration, so it's clearly unsafe to try to call it without seeing a declaration.
* Fix saveHistory() to not emit bogus complaint during psql exit when usingTom Lane2006-06-18
| | | | | Darwin's libedit; per my proposal last August. Also, suppress cast-away- const warnings.
* Increase timeout in statement_timeout test from 1 second to 2 seconds.Tom Lane2006-06-18
| | | | | | | | | We have once or twice seen failures suggesting that control didn't get to the exception block before the timeout elapsed, which is unlikely but not impossible in a parallel regression test (with a dozen other backends competing for cycles). This change doesn't completely prevent the problem of course, but it should reduce the probability enough that we don't see it anymore. Per buildfarm results.

* Fix problems with cached tuple descriptors disappearing while still in useTom Lane2006-06-16
| | | | | | | | | | by creating a reference-count mechanism, similar to what we did a long time ago for catcache entries. The back branches have an ugly solution involving lots of extra copies, but this way is more efficient. Reference counting is only applied to tupdescs that are actually in caches --- there seems no need to use it for tupdescs that are generated in the executor, since they'll go away during plan shutdown by virtue of being in the per-query memory context.
