* New async/sync multi-master headings for docs.Bruce Momjian2006-11-22

* Add mention of shared-memory/disk for multi-master clustering.Bruce Momjian2006-11-22
|
* Get rid of retail definitions of HAVE_STRDUP and HAVE_VSNPRINTF inTom Lane2006-11-21
| | | | | some of the Windows-only makefiles; the correct place to assert these things is pg_config.h.win32. Per bug #2677.
* Translate Windows' GMT Standard Time/GMT Daylight Time zones toTom Lane2006-11-21
| | | | | | | | zic's Europe/London, rather than Europe/Dublin as before. This seems a less surprising choice, particularly with respect to dates before 1948. Original suggestion was to translate to straight GMT, but this seems wrong given that these zones *are* DST-aware. Per offlist discussion with Magnus.
* HA doc wording improvement.Bruce Momjian2006-11-21

* Prevent intratransaction memory leak when a subtransaction is abortedTom Lane2006-11-21
| | | | | | in the middle of executing a SPI query. This doesn't entirely fix the problem of memory leakage in plpgsql exception handling, but it should get rid of the lion's share of leakage.
* Suppress timezone (%Z) part of timestamp display when running on Windows,Tom Lane2006-11-21
| | | | | | | | | because on that platform strftime produces localized zone names in varying encodings. Even though it's only in a comment, this can cause encoding errors when reloading the dump script. Per suggestion from Andreas Seltenreich. Also, suppress %Z on Windows in the %s escape of log_line_prefix ... not sure why this one is different from the other two, but it shouldn't be.
* Fix plpython to work (or at least pass its regression tests) withTom Lane2006-11-21
| | | | | | python 2.5. This involves fixing several violations of the published spec for creating PyTypeObjects, and adding another regression test expected output for yet another variation of error message spelling.
* Mention pgpool-II can do Clustering For Parallel Query Execution.Bruce Momjian2006-11-21

* On systems that have setsid(2) (which should be just about everything exceptTom Lane2006-11-21
| | | | | | | | | | | | | Windows), arrange for each postmaster child process to be its own process group leader, and deliver signals SIGINT, SIGTERM, SIGQUIT to the whole process group not only the direct child process. This provides saner behavior for archive and recovery scripts; in particular, it's possible to shut down a warm-standby recovery server using "pg_ctl stop -m immediate", since delivery of SIGQUIT to the startup subprocess will result in killing the waiting recovery_command. Also, this makes Query Cancel and statement_timeout apply to scripts being run from backends via system(). (There is no support in the core backend for that, but it's widely done using untrusted PLs.) Per gripe from Stephen Harris and subsequent discussion.

* In HA/load balancing does:Bruce Momjian2006-11-21
| | | | | | Clarify sync/async replication propogation delay issues. Add SGML comment about Oracle RAC and remove doc mention. Add item about Multi-master replication with conflict resolution.
* VC build patch from Magnus:Neil Conway2006-11-21
| | | | | | | | Typo in the changes to plperl - uses wrong dir, and had a missing slash. Also fixes error checking for xsubpp - it was broken in a way that hid the problem above when run more than once (which is the normal case when developing).
* Move libpq environment reference in psql documentation to a moreBruce Momjian2006-11-21

* remove duplicate declaration, per report from Magnus Hagander.Andrew Dunstan2006-11-21

* If SSL negotiation fails and SSLMODE is 'prefer', then retry without SSL.Tom Lane2006-11-21
| | | | | | | Negotiation failure is only likely to happen if one side or the other is misconfigured, eg. bad client certificate. I'm not 100% convinced that a retry is really the best thing, hence not back-patching this fix for now. Per gripe from Sergio Cinos.
* Add capitalization mention.Bruce Momjian2006-11-21

* I noticed that the Partitioning section of the docs has *two* sectionsBruce Momjian2006-11-21
| | | | | | | | of caveats in different places, but close together. One called caveats, one not. That looks like it just led to somebody not reading some appropriate caveats in the second group of caveats (on -admin). Simon Riggs
* Change the default setting for log_min_error_statement to ERROR. PerTom Lane2006-11-21
| | | | | recent discussion in which majority opinion was that this is a more widely useful setting than the previous default of PANIC.
* Adjust elog.c so that elog(FATAL) exits (including cases where ERROR isTom Lane2006-11-21
| | | | | | | | | | | | | | | | promoted to FATAL) end in exit(1) not exit(0). Then change the postmaster to allow exit(1) without a system-wide panic, but not for the startup subprocess or the bgwriter. There were a couple of places that were using exit(1) to deliberately force a system-wide panic; adjust these to be exit(2) instead. This fixes the problem noted back in July that if the startup process exits with elog(ERROR), the postmaster would think everything is hunky-dory and proceed to start up. Alternative solutions such as trying to run the entire startup process as a critical section seem less clean, primarily because of the fact that a fair amount of startup code is shared by all postmaster children in the EXEC_BACKEND case. We'd need an ugly special case somewhere near the head of main.c to make it work if it's the child process's responsibility to determine what happens; and what's the point when the postmaster already treats different children differently?

* More MSVC build fixes:Tom Lane2006-11-20
| | | | | | | | | | | | | | | | | * New versions of OpenSSL come with proper debug versions, and use suffixed names on the LIBs for that. Adapts library handling to deal with that. * Fixes error where it incorrectly enabled Kerberos based on NLS configuration instead of Kerberos configuration * Specifies path of perl in config, instead of using current one. Required when using a 64-bit perl normally, but want to build pl/perl against 32-bit one (required) * Fix so pgevent generates win32ver.rc automatically Magnus Hagander
* Overhaul the "External Projects" chapter in the manual. ReplaceNeil Conway2006-11-20

| | | | | | | Fix string's length calculation for recoding, fix strlower() to avoid wrong assumption about length of recoded string (was: recoded string is no greater that source, it may not true for multibyte encodings) Thanks to Thomas H. <me@alternize.com> and Magnus Hagander <mha@sollentuna.net>
* When truncating a relation in-place (eg during VACUUM), do not try to unlinkTom Lane2006-11-20
| | | | | | | | | | | | | any no-longer-needed segments; just truncate them to zero bytes and leave the files in place for possible future re-use. This avoids problems when the segments are re-used due to relation growth shortly after truncation. Before, the bgwriter, and possibly other backends, could still be holding open file references to the old segment files, and would write dirty blocks into those files where they'd disappear from the view of other processes. Back-patch as far as 8.0. I believe the 7.x branches are not vulnerable, because they had no bgwriter, and "blind" writes by other backends would always be done via freshly-opened file references.
* Repair problems with hash indexes that span multiple segments: the hash code'sTom Lane2006-11-19
| | | | | | | | | | | | | | | | | | preference for filling pages out-of-order tends to confuse the sanity checks in md.c, as per report from Balazs Nagy in bug #2737. The fix is to ensure that the smgr-level code always has the same idea of the logical EOF as the hash index code does, by using ReadBuffer(P_NEW) where we are adding a single page to the end of the index, and using smgrextend() to reserve a large batch of pages when creating a new splitpoint. The patch is a bit ugly because it avoids making any changes in md.c, which seems the most prudent approach for a backpatchable beta-period fix. After 8.3 development opens, I'll take a look at a cleaner but more invasive patch, in particular getting rid of the now unnecessary hack to allow reading beyond EOF in mdread(). Backpatch as far as 7.4. The bug likely exists in 7.3 as well, but because of the magnitude of the 7.3-to-7.4 changes in hash, the later-version patch doesn't even begin to apply. Given the other known bugs in the 7.3-era hash code, it does not seem worth trying to develop a separate patch for 7.3.
* Clarify description of CIDR-address column of pg_hba.conf, to discourageTom Lane2006-11-17
| | | | | people from trying notations like '10.6/16', which is accepted but does not mean what you probably think. Per example from Paul Forgey.
* Repair two related errors in heap_lock_tuple: it was failing to recognizeTom Lane2006-11-17
| | | | | | | | | cases where we already hold the desired lock "indirectly", either via membership in a MultiXact or because the lock was originally taken by a different subtransaction of the current transaction. These cases must be accounted for to avoid needless deadlocks and/or inappropriate replacement of an exclusive lock with a shared lock. Per report from Clarence Gardner and subsequent investigation.
