| | | | | | | | agreement with what the backend grammar actually accepts (which is a bit looser than what its documentation claims). Per report from Bill Moran, though I did not use his patch since it removed all the undocumented flexibility that the code historically had and the backend still has.

* - Issue a warning if a cursor is declared but not opened.Michael Meskes2004-01-28
| | | | | | - Fixed prototype for ECPGprepared_statement to not moan about "const char" - Fixed parsing of nested structures. - Added option to parse header files.
* Fix oversight in check_ungrouped_columns optimization that avoidsTom Lane2004-01-28
| | | | | | | unnecessary checks for complex grouping expressions: we cannot check whether the expressions are simple Vars until after we apply flatten_join_alias_vars, because in the case of FULL JOIN that routine can introduce non-Var expressions. Per example from Joel Knight.
* simplify_function() mustn't try to evaluate functions that returnTom Lane2004-01-28
| | | | | | | composite types, because TupleTableSlots aren't Datums and can't be stored in Const nodes. We can remove this restriction if we ever adopt a cleaner runtime representation for whole-tuple results, but at the moment it's broken. Per example from Thomas Hallgren.
* Improve the documentation of the 'join_collapse_limit' GUC var. Thanks toNeil Conway2004-01-27
| | | | Tom Lane for some editorial suggestions.
* Run stats test separately, not as part of a parallel group, to avoidTom Lane2004-01-27
| | | | | possible failures due to stats collector not updating fast enough under heavy load. Per report from Jeremy Yoder.
* Pgindent win32 signal code.Bruce Momjian2004-01-27

* Here's the latest win32 signals code, this time in the form of a patchBruce Momjian2004-01-27
| | | | | | | | | | | | | | | | | against the latest shapshot. It also includes the replacement of kill() with pqkill() and sigsetmask() with pqsigsetmask(). Passes all tests fine on my linux machine once applied. Still doesn't link completely on Win32 - there are a few things still required. But much closer than before. At Bruce's request, I'm goint to write up a README file about the method of signals delivery chosen and why the others were rejected (basically a summary of the mailinglist discussions). I'll finish that up once/if the patch is accepted. Magnus Hagander
* [all] Removed call to getppid in SendPostmasterSignal, replacing with aBruce Momjian2004-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | PostmasterPid variable, which gets set (early) in PostmasterMain getppid would not be the postmaster? [fork/exec] Implements processCancelRequest by keeping an array of pid/cancel_key structs in shared mem [fork/exec] Moves AttachSharedMemoryAndSemaphores call for backends into SubPostmasterMain [win32] Implements reaper/waitpid by keeping an arrays of children pids,handles in postmaster local mem - this item is largely untested, for reasons which should be obvious, but appears sound [win32/all] Added extern for pgpipe in Win32 case, and changed the second pipe call (which seems to have been missed earlier) to pgpipe [win32] #define'd ftruncate to chsize in the Win32 case [win32] PG_USLEEP for Win32 has a misplaced paren. Fixed. [win32] DLLIMPORT handling for MingW case Claudio Natoli

| | | | > * -Add checks for fclose() failure (Tom)
* Ensure that close() and fclose() are checked for errors, at least inTom Lane2004-01-26
| | | | | | cases involving writes. Per recent discussion about the possibility of close-time failures on some filesystems. There is a TODO item for this, too.

* Repair incorrect order of operations in GetNewTransactionId(). We mustTom Lane2004-01-26

* Mention that log_statement only prints query on PREPARE, not EXECUTE,Bruce Momjian2004-01-25

* Support named parameters in information_schema.parameters,Tom Lane2004-01-24

* Revert the change to print.c, as this breaks src/bin/scripts. The properNeil Conway2004-01-24
| | | | | | way to fix this is probably implementing safe memory handling functions once in a static lib and then using that in the various client apps, but for the moment I've just reverted the change to un-break the tree.

* This patch makes some of the memory manipulation performed by psql aNeil Conway2004-01-24
| | | | | | | little more sane. Some parts of the code was using a static function xmalloc() that did safe memory allocation (where "safe" means "bail out on OOM"), but most of it was just invoking calloc() or malloc() directly. Now almost everything invokes xmalloc() or xcalloc().

* Repair planner failure for cases involving Cartesian products insideTom Lane2004-01-24
| | | | | | IN (sub-SELECT) constructs. We must force a clauseless join of the sub-select member relations, but it wasn't happening because the code thought it would be able to use the join clause arising from the IN.
* Revise GEQO planner to make use of some heuristic knowledge about SQL, namelyTom Lane2004-01-23
| | | | | | | | | | | | | | that it's good to join where there are join clauses rather than where there are not. Also enable it to generate bushy plans at need, so that it doesn't fail in the presence of multiple IN clauses containing sub-joins. These changes appear to improve the behavior enough that we can substantially reduce the default pool size and generations count, thereby decreasing the runtime, and yet get as good or better plans as we were getting in 7.4. Consequently, adjust the default GEQO parameters. I also modified the way geqo_effort is used so that it affects both population size and number of generations; it's now useful as a single control to adjust the GEQO runtime-vs-plan-quality tradeoff. Bump geqo_threshold to 12, since even with these changes GEQO seems to be slower than the regular planner at 11 relations.
