* Replaced $Header$ by $§PosgreSQL$Michael Meskes2006-07-30

* Added missing $Header$ entries.Michael Meskes2006-07-30
|
* Modify snapshot definition so that lazy vacuums are ignored by otherAlvaro Herrera2006-07-30
| | | | | | | | | vacuums. This allows a OLTP-like system with big tables to continue regular vacuuming on small-but-frequently-updated tables while the big tables are being vacuumed. Original patch from Hannu Krossing, rewritten by Tom Lane and updated by me.
* Fix WIN32 wait() return value macros to be accurate, particularlyBruce Momjian2006-07-30
| | | | | | | | | because they are used for testing the return value from system(). (WIN32 doesn't overlay the return code with other failure conditions like Unix does, so they are just simple macros.) Fix regression checks to properly handle diff failures on Win32 using the new macros.
* prevent multiplexing Windows kernel event objects we listen for across ↵Andrew Dunstan2006-07-29
| | | | various sockets - should fix the occasional stats test regression failures we see.
* Don't use #include <crtdefs.h> for MSVC <= 1400.Bruce Momjian2006-07-29
| | | | Hiroshi Saito
* Add #include postgres_fe.h in two win32-specific files, because there isBruce Momjian2006-07-29
| | | | pg-specific code in those files, or might be some day.
* Adjust initialization sequence for timezone_abbreviations so thatTom Lane2006-07-29
| | | | | | | | | it's handled just about like timezone; in particular, don't try to read anything during InitializeGUCOptions. Should solve current startup failure on Windows, and avoid wasted cycles if a nondefault setting is specified in postgresql.conf too. Possibly we need to think about a more general solution for handling 'expensive to set' GUC options.
* SQL2003-standard statistical aggregates, by Sergey Koposov. I've added onlyTom Lane2006-07-28
| | | | | | | the float8 versions of the aggregates, which is all that the standard requires. Sergey's original patch also provided versions using numeric arithmetic, but given the size and slowness of the code, I doubt we ought to include those in core.
* Variables should be free'ed only once.Michael Meskes2006-07-28

* Removed superfluous commentMichael Meskes2006-07-28

* And one more:Michael Meskes2006-07-28
| | | | Connection identifier has to be unique
* Added more SoC changes by Joachim Wieland <joe@mcknight.de>:Michael Meskes2006-07-28
| | | | | - SHOW statement puts result into a variable - COPY TO STDOUT works
* Aggregate functions now support multiple input arguments. I also tookTom Lane2006-07-27
| | | | | | | | the opportunity to treat COUNT(*) as a zero-argument aggregate instead of the old hack that equated it to COUNT(1); this is materially cleaner (no more weird ANYOID cases) and ought to be at least a tiny bit faster. Original patch by Sergey Koposov; review, documentation, simple regression tests, pg_dump and psql support by moi.
* Original coding of pg_regress.c made the results and log directoriesTom Lane2006-07-27
| | | | | with restrictive permissions, which was not the behavior of the shell script and doesn't seem very desirable. Use the umask setting instead.
* Allow LDAP lookups from pg_service.conf.Bruce Momjian2006-07-27
| | | | Albe Laurenz
* Allow units to be specified with configuration settings.Peter Eisentraut2006-07-27
|
* Code review for bigint-LIMIT patch. Fix missed planner dependency,Tom Lane2006-07-26
| | | | | | eliminate unnecessary code, force initdb because stored rules change (limit nodes are now supposed to be int8 not int4 expressions). Update comments and error messages, which still all said 'integer'.
* Work around bug in strxfmt() but in MS VS2005.Bruce Momjian2006-07-26
| | | | William ZHANG
* When a GUC string variable is not set, print the empty string (in SHOW etc.),Peter Eisentraut2006-07-26
| | | | | | not "unset". An "unset" state doesn't really exist; all variables behave like an empty string value if the string being pointed to has not been initialized.
* Convert effective_cache_size to an integer, for better integration withPeter Eisentraut2006-07-26
| | | | upcoming units feature.
* Change LIMIT/OFFSET to use int8Bruce Momjian2006-07-26
| | | | Dhanaraj M
* Modify btree to delete known-dead index entries without an actual VACUUM.Tom Lane2006-07-25
| | | | | | | | | | When we are about to split an index page to do an insertion, first look to see if any entries marked LP_DELETE exist on the page, and if so remove them to try to make enough space for the desired insert. This should reduce index bloat in heavily-updated tables, although of course you still need VACUUM eventually to clean up the heap. Junji Teramoto
* Add missing @OVERRIDE to 'India' config file, per Michael Fuhr.Tom Lane2006-07-25
| | | | Add $PostgreSQL$ lines for CVS identity, too.
* Remove hard-wired lists of timezone abbreviations in favor of providingTom Lane2006-07-25
| | | | | | | | | configuration files that can be altered by a DBA. The australian_timezones GUC setting disappears, replaced by a timezone_abbreviations setting (set this to 'Australia' to get the effect of australian_timezones). The list of zone names defined by default has undergone a bit of cleanup, too. Documentation still needs some work --- in particular, should we fix Table B-4, or just get rid of it? Joachim Wieland, with some editorializing by moi.
* Use correct ifdef test for cygwin, namely __CYGWIN__ (note underscores).Andrew Dunstan2006-07-25

* Make the order of operations in PostmasterMain a bit saner ... someTom Lane2006-07-25
| | | | recent patches had added stuff in rather random spots.
* DTrace support, with a small initial set of probesPeter Eisentraut2006-07-24

* Remove dubious and redundant (we think) setting of libdir in PATH for non ↵Andrew Dunstan2006-07-24
| | | | temp-install case.
* Add a fudge factor to genericcostestimate() to prevent the planner fromTom Lane2006-07-24
| | | | | | | thinking that indexes of different sizes are equally attractive. Per gripe from Jim Nasby. (I remain unconvinced that there's such a problem in existing releases, but CVS HEAD definitely has got a problem because of its new count-only-leaf-pages approach to indexscan costing.)
* Convert the lock manager to use the new dynahash.c support for partitionedTom Lane2006-07-23
| | | | | hash tables, instead of the previous kluge involving multiple hash tables. This partially undoes my patch of last December.
* Fix oversight in sizing of shared buffer lookup hashtable. BecauseTom Lane2006-07-23
| | | | | | | | | BufferAlloc tries to insert a new mapping entry before deleting the old one for a buffer, we have a transient need for more than NBuffers entries --- one more in 8.1, and as many as NUM_BUFFER_PARTITIONS more in CVS HEAD. In theory this could lead to an "out of shared memory" failure if shmem had already been completely claimed by the time the extra entries were needed.
* Split the buffer mapping table into multiple separately lockableTom Lane2006-07-23
| | | | | partitions, as per discussion. Passes functionality checks, but I don't have any performance data yet.
* Add support to dynahash.c for partitioning shared hashtables accordingTom Lane2006-07-22
| | | | | | to the low-order bits of the entry hash value. Also make some incidental cleanups in the dynahash API, such as not exporting the hash header structs to the world.
* Hmm, seems --disable-spinlocks has been broken for awhile and nobodyTom Lane2006-07-22
| | | | | noticed. Fix SpinlockSemas() to report the correct count considering that PG 8.1 adds a spinlock to each shared-buffer header.
* In the recent changes to make the planner account better for cacheTom Lane2006-07-22
| | | | | | | effects in a nestloop inner indexscan, I had only dealt with plain index scans and the index portion of bitmap scans. But there will be cache benefits for the heap accesses of bitmap scans too, so fix cost_bitmap_heap_scan() to account for that.
* Add libdir to PATH for Cygwin as well as WIN32 - should fix buildfarm eel.Andrew Dunstan2006-07-22
|
* For automatic dependency tracking, replace our sed hackery with the GCC-Peter Eisentraut2006-07-21
| | | | | | -built-in mechanism through the -MP flag. Adjust the file extensions to look more like Automake practice. This frees up the .d suffix for use by DTrace.
* Add the full set of comparison functions for type TID, including a btreeTom Lane2006-07-21
| | | | | | | | opclass. This is not so much because anyone's likely to create an index on TID, as that sorting TIDs can be useful. Also added max and min aggregates while at it, so that one can investigate the clusteredness of a table with queries like SELECT min(ctid), max(ctid) FROM tab WHERE ... Greg Stark and Tom Lane
* Ah, I finally realize why Magnus wanted to add a --bindir option toTom Lane2006-07-21
| | | | | | | | | pg_regress: there's no other way to cope with testing a relocated installation. Seems better to call it --psqldir though, since the only thing we need to find in that case is psql. It'd be better if we could use find_other_exec, but that's not happening unless we are willing to install pg_regress alongside psql, which seems unlikely to happen.
* As a stopgap to get the Windows buildfarm members running again, hot-wireTom Lane2006-07-20
| | | | | | the check on diff's exit status to check for literally 0 or 1. Someone should look into why WIFEXITED/WEXITSTATUS don't work for this, but I've spent more than enough time on it already.
* Make pg_config location overridable for pgxs builds.Peter Eisentraut2006-07-20
|
* Print out diff status code when we think there's a hard failure.Tom Lane2006-07-20
| | | | May help in debugging behavior on Windows.
* Suppress unused-variable compiler warning, per Andrew Dunstan.Tom Lane2006-07-20
|
* Fix pg_regress.c to report tests in a parallel group when they finish,Tom Lane2006-07-20
| | | | | | not when they're started. This mimics a subtle point of the behavior of the old shell script, and gives better feedback when watching the tests.
* Make pg_regress.c get paths from pg_config_paths.h, instead of -DTom Lane2006-07-20
| | | | | switches passed from the Makefile. This looks like it will fix problem with virtual vs real paths under msys.
* Don't try to truncate multixact SLRU files in checkpoints done during xlogTom Lane2006-07-20
| | | | | | | | | | | recovery. In the first place, it doesn't work because slru's latest_page_number isn't set up yet (this is why we've been hearing reports of strange "apparent wraparound" log messages during crash recovery, but only from people who'd managed to advance their next-mxact counters some considerable distance from 0). In the second place, it seems a bit unwise to be throwing away data during crash recovery anwyway. This latter consideration convinces me to just disable truncation during recovery, rather than computing latest_page_number and pushing ahead.
* Adjust spawn_process() to avoid unnecessary overhead processes: we canTom Lane2006-07-19
| | | | | | just exec instead of creating a subprocess. This reduces process usage from four processes per parallel test to two. I have no idea whether a comparable optimization is possible or useful in the Windows port.
* Update WIN32 quoting roles documentation.Bruce Momjian2006-07-19
