* Clean up backend-exit-time cleanup behavior. Use on_shmem_exit callbacksTom Lane2000-12-18
| | | | | | to ensure that we have released buffer refcounts and so forth, rather than putting ad-hoc operations before (some of the calls to) proc_exit. Add commentary to discourage future hackers from repeating that mistake.
* Remove a few remaining vestiges of elog(WARN).Tom Lane2000-12-15
|
* Planner speedup hacking. Avoid saving useless pathkeys, so that pathTom Lane2000-12-14
| | | | | | | | | | | | comparison does not consider paths different when they differ only in uninteresting aspects of sort order. (We had a special case of this consideration for indexscans already, but generalize it to apply to ordered join paths too.) Be stricter about what is a canonical pathkey to allow faster pathkey comparison. Cache canonical pathkeys and dispersion stats for left and right sides of a RestrictInfo's clause, to avoid repeated computation. Total speedup will depend on number of tables in a query, but I see about 4x speedup of planning phase for a sample seven-table query.
* Cache eval cost of qualification expressions in RestrictInfo nodes toTom Lane2000-12-12
| | | | | | | avoid repeated evaluations in cost_qual_eval(). This turns out to save a useful fraction of planning time. No change to external representation of RestrictInfo --- although that node type doesn't appear in stored rules anyway.

* Correct one description, add one.Peter Eisentraut2000-12-10

* Repair erroneous use of hashvarlena() for MACADDR, which is not aTom Lane2000-12-08
| | | | | | | varlena type. (I did not force initdb, but you won't see the fix unless you do one.) Also, make sure all index support operators and functions are careful not to leak memory for toasted inputs; I had missed some hash and rtree support ops on this point before.
* Resurrect -F switch: it controls fsyncs again, though the fsyncs areTom Lane2000-12-08
| | | | | mostly just on the WAL logfile nowadays. But if people want to disable fsync for performance, why should we say no?
* REINDEX under WAL.Hiroshi Inoue2000-12-08
|
* Make OVERLAPS operators conform to SQL92 spec regarding NULL handling.Tom Lane2000-12-07
| | | | | | | | | | As I read it, the spec requires a non-null result in some cases where one of the inputs is NULL: specifically, if the other endpoint of that interval is between the endpoints of the other interval, then the result is known TRUE despite the missing endpoint. The spec could've been a lot simpler if they did not intend this behavior. I did not force an initdb for this change, but if you don't do one you'll still see the old strict-function behavior.
* Clean up handling of FOR UPDATE inside views and subselects ... make itTom Lane2000-12-06
| | | | | | | work where we can (given that the executor only handles it at top level) and generate an error where we can't. Note that while the parser has been allowing views to say SELECT FOR UPDATE for a few weeks now, that hasn't actually worked until just now.
* Don't include miscadmin.h in elog.h, since the former is not part ofTom Lane2000-12-06
| | | | the installed header file set.
* Repair breakage of rules containing INSERT ... SELECT actions, per bugTom Lane2000-12-05
| | | | | | | | | | | report from Joel Burton. Turns out that my simple idea of turning the SELECT into a subquery does not interact well *at all* with the way the rule rewriter works. Really what we need to make INSERT ... SELECT work cleanly is to decouple targetlists from rangetables: an INSERT ... SELECT wants to have two levels of targetlist but only one rangetable. No time for that for 7.1, however, so I've inserted some ugly hacks to make the rewriter know explicitly about the structure of INSERT ... SELECT queries. Ugh :-(
* Ensure that all uses of <ctype.h> functions are applied to unsigned-charTom Lane2000-12-03
| | | | | values, whether the local char type is signed or not. This is necessary for portability. Per discussion on pghackers around 9/16/00.
* Don't use 'private' as a parameter name in visible headers ... makes C++Tom Lane2000-12-03
| | | | very unhappy ...
* Repair usage of the OVERLAPS operator.Thomas G. Lockhart2000-12-03
| | | | | | | | Allow some operator-like tokens to be used as function names. Flesh out support for time, timetz, and interval operators and interactions. Regression tests pass, but non-reference-platform horology test results will need to be updated.
* Support IBM S/390. Patches from Neale Ferguson@softwareAG-usa.com.Thomas G. Lockhart2000-12-03
|
* Disable elog(ERROR|FATAL) in signal handlers inVadim B. Mikheev2000-12-03
| | | | critical sections of code.
* Don't cause --enable-cassert to define COPY_PARSE_PLAN_TREES automaticallyTom Lane2000-12-02
| | | | | | | | anymore. That won't teach us anything new for the rest of this release cycle, so it seems better to keep the --assert environment more like the non-assert environment for beta. I'm going to leave CLOBBER_FREED_MEMORY and MEMORY_CONTEXT_CHECKING turned on by --enable-cassert for now, however.
* Make tuple receive/print routines TOAST-aware. Formerly, printtup wouldTom Lane2000-12-01
| | | | | leak memory when printing a toasted attribute, and printtup_internal didn't work at all...
* Pursuant to a pghackers discussion back around 11-Jul-00, get rid of aset.c'sTom Lane2000-12-01
| | | | | | | not-very-good handling of mid-size allocation requests. Do everything via either the "small" case (chunk size rounded up to power of 2) or the "large" case (pass it straight off to malloc()). Increase the number of freelists a little to set the breakpoint between these behaviors at 8K.
* Clean up MEMORY_CONTEXT_CHECKING code, and apply it more thoroughly. Also,Tom Lane2000-12-01
| | | | | apply Karel Zak's patch to recycle residual space in an exhausted allocation block. (Bet you thought I'd forgot about that, Karel?)
* Make default socket directory location configurable from config.h.Tom Lane2000-11-30
| | | | | If we're going to let it be run-time configurable, might as well allow this too...
* Remove DISABLE_COMPLEX_MACRO definitions, since people seem to be gettingPeter Eisentraut2000-11-30
| | | | | | | by without them. Don't check for preprocessor symbols from system header files in port include files, since those header files aren't included at this point.
* Remove VARLENA_FIXED_SIZE hack, which is irreversibly broken now thatTom Lane2000-11-30
| | | | | | | | both MULTIBYTE and TOAST prevent char(n) from being truly fixed-size. Simplify and speed up fastgetattr() and index_getattr() macros by eliminating special cases for attnum=1. It's just as fast to handle the first attribute by presetting its attcacheoff to zero; so do that instead when loading the tupledesc in relcache.c.
* No more #ifdef XLOG.Vadim B. Mikheev2000-11-30
|
* XLOG stuff for sequences.Vadim B. Mikheev2000-11-30
| | | | CommitDelay in guc.c
* Rearrange bufmgr header files so that buf_internals.h need not beTom Lane2000-11-30
| | | | | | | included by everything that includes bufmgr.h --- it's supposed to be internals, after all, not part of the API! This fixes the conflict against FreeBSD headers reported by Rosenman, by making it unnecessary for s_lock.h to be included by plperl.c.
* Get rid of not-very-portable fcntl(F_SETLK) mechanism for locking the UnixTom Lane2000-11-29
| | | | | | | | | socket file, in favor of having an ordinary lockfile beside the socket file. Clean up a few robustness problems in the lockfile code. If postmaster is going to reject a connection request based on database state, it will now tell you so before authentication exchange not after. (Of course, a failure after is still possible if conditions change meanwhile, but this makes life easier for a yet-to-be-written pg_ping utility.)
* Significant cleanups in SysV IPC handling (shared mem and semaphores).Tom Lane2000-11-28
| | | | | | | | | | | IPC key assignment will now work correctly even when multiple postmasters are using same logical port number (which is possible given -k switch). There is only one shared-mem segment per postmaster now, not 3. Rip out broken code for non-TAS case in bufmgr and xlog, substitute a complete S_LOCK emulation using semaphores in spin.c. TAS and non-TAS logic is now exactly the same. When deadlock is detected, "Deadlock detected" is now the elog(ERROR) message, rather than a NOTICE that comes out before an unhelpful ERROR.
* Make PGLC_setlocale() static, and document that it can't be used safelyTom Lane2000-11-25
| | | | | | | | | | | for any other purpose than PGLC_localeconv()'s internal save/restore of locale settings. Fix cash.c to call PGLC_localeconv() rather than making a direct call to localeconv() --- the old way, if PGLC_localeconv() had already cached a locale result, it would be overwritten by the first cash_in or cash_out operation, leading to wrong-locale results later. Probably no demonstrable bug today, since we only appear to be looking at the LC_MONETARY results which should be the same anyway, but definitely a gotcha waiting to strike.
* Move connection defines to miscadmin.h.Bruce Momjian2000-11-25
|
* Store current LC_COLLATE and LC_CTYPE settings in pg_control during initdb;Tom Lane2000-11-25
| | | | | | | | | | re-adopt these settings at every postmaster or standalone-backend startup. This should fix problems with indexes becoming corrupt due to failure to provide consistent locale environment for postmaster at all times. Also, refuse to start up a non-locale-enabled compilation in a database originally initdb'd with a non-C locale. Suppress LIKE index optimization if locale is not "C" or "POSIX" (are there any other locales where it's safe?). Issue NOTICE during initdb if selected locale disables LIKE optimization.
* here is a patch for formatting.c (to_char/timestampt()), for 7.1Bruce Momjian2000-11-25
| | | | | | | | | | | | it fixing Y,YY,YYY,YYYY conversion, the docs and regress tests update are included too. During the patch testing I found small bug in miscadmin.h in convertstr() declaration. Here it's fixed too. Thanks Karel
* Rename GUC name from unixsocket to unix_socket_directoryBruce Momjian2000-11-25
|
* Make SET SESSION CHARACTERISTICS compliant with SQL 99. Remove redundant,Peter Eisentraut2000-11-24
| | | | | non-standard clauses. Allow CHARACTERISTICS as unquoted identifier. Merge related reference pages.
* A catalog cache that never caches isn't much of a cache :-(. Mea culpa.Tom Lane2000-11-24
| | | | Thanks to Brian Hirt for pointing out the performance lossage.
* Recommit socket path fix. It works now.Bruce Momjian2000-11-22
|
* Back out socket path until it works.Bruce Momjian2000-11-22
|
* Back out socket file path change until it works.Bruce Momjian2000-11-22
|
* Make socket option specify just the directory, not the full path.Bruce Momjian2000-11-22
|
* Extend accept/AF_UNIX bug workaround to SCO OpenServer.Peter Eisentraut2000-11-21
|
* Put external declarations into header files.Peter Eisentraut2000-11-21
|
* Make oidin/oidout produce and consume unsigned representation of Oid,Tom Lane2000-11-21
| | | | | | | | | | | | rather than just being aliases for int4in/int4out. Give type Oid a full set of comparison operators that do proper unsigned comparison, instead of reusing the int4 comparators. Since pg_dump is now doing unsigned comparisons of OIDs, it is now *necessary* that we play by the rules here. In fact, given that btoidcmp() has been doing unsigned comparison for quite some time, it seems likely that we have index- corruption problems in 7.0 and before once the Oid counter goes past 2G. Fixing these operators is a necessary step before we can think about 8-byte Oid, too.
* No casting to LSN (XLogRecPtr) is required.Vadim B. Mikheev2000-11-20
|
* Revise handling of oldstyle/newstyle functions per recent discussionsTom Lane2000-11-20
| | | | | | | | | in pghackers list. Support for oldstyle internal functions is gone (no longer needed, since conversion is complete) and pg_language entry 'internal' now implies newstyle call convention. pg_language entry 'newC' is gone; both old and newstyle dynamically loaded C functions are now called language 'C'. A newstyle function must be identified by an associated info routine. See src/backend/utils/fmgr/README.
* Enable WAL in config.h, not Makefile.global.Peter Eisentraut2000-11-20
|
* Add configure checks for strtoll, strtoull (or strto[u]q). DisablePeter Eisentraut2000-11-20
| | | | | 'long long int' portions of ecpg if the type or these functions don't exist.
* Compile WAL by default.Vadim B. Mikheev2000-11-20
