<p><strong>La fonctionnalit&eacute; 8.5 de la semaine</strong></p>
<p>VACUUM FULL a &eacute;t&eacute; modifi&eacute; pour g&eacute;n&eacute;rer maintenant de nouveaux fichiers des tables et index trait&eacute;s. Ceci est bas&eacute; sur l'ancienne commande CLUSTER et s'av&egrave;re plus efficient. L'ancienne fonctionnalit&eacute; est toujours accessible via VACUUM FULL INPLACE, mais sera incompatible avec le Hot Standby.</p>
<p><strong>L'astuce de la semaine</strong></p>
<p>En activant la surveillance des fichiers temporaires gr&acirc;ce &agrave; l'option 'log_temp_files', vous pouvez savoir s'il y a besoin d'augmenter les param&egrave;tres 'work_mem' ou 'maintenance_work_mem' pour vos bases de donn&eacute;es.</p>

<p><strong>Correctifs appliqu&eacute;s</strong></p>
<p>Andrew Dunstan a commit&eacute;&nbsp;:</p>
<ul>
<li>In pgsql/src/tools/msvc/Mkvcbuild.pm, remove use of temp file for perlchunks.h, as in recent change to plperl GNUmakefile</li>
</ul>
<p>Tom Lane a commit&eacute;&nbsp;:</p>
<ul>
<li>In pgsql/src/backend/executor/execQual.c, improve ExecEvalVar's handling of whole-row variables in cases where the rowtype contains dropped columns. Sometimes the input tuple will be formed from a select targetlist in which dropped columns are filled with a NULL of an arbitrary type (the planner typically uses INT4, since it can't tell what type the dropped column really was). So we need to relax the rowtype compatibility check to not insist on physical compatibility if the actual column value is NULL. In principle we might need to do this for functions returning composite types, too (see tupledesc_match()). In practice there doesn't seem to be a bug there, probably because the function will be using the same cached rowtype descriptor as the caller. Fixing that code path would require significant rearrangement, so I left it alone for now. Per complaint from Filip Rembialkowski.</li>
<li>Add some simple support and documentation for using process-specific oom_adj settings to prevent the postmaster from being OOM-killed on Linux systems. Alex Hunsaker and Tom Lane.</li>
<li>In pgsql/src/backend/utils/adt/acl.c, fix aclexplode to not explode on a zero-entry ACL array. (An Assert is no substitute for thinking clearly :-() Minor style kibitzing too. Per report from Robert Treat.</li>
<li>In pgsql/src/backend/utils/cache/relcache.c, fix relcache reload mechanism to be more robust in the face of errors occurring during a reload, such as query-cancel. Instead of zeroing out an existing relcache entry and rebuilding it in place, build a new relcache entry, then swap its contents with the old one, then free the new entry. This avoids problems with code believing that a previously obtained pointer to a cache entry must still reference a valid entry, as seen in recent failures on buildfarm member jaguar. (jaguar is using CLOBBER_CACHE_ALWAYS which raises the probability of failure substantially, but the problem could occur in the field without that.) The previous design was okay when it was made, but subtransactions and the ResourceOwner mechanism make it unsafe now. Also, make more use of the already existing rd_isvalid flag, so that we remember that the entry requires rebuilding even if the first attempt fails. Back-patch as far as 8.2. Prior versions have enough issues around relcache reload anyway (due to inadequate locking) that fixing this one doesn't seem worthwhile.</li>
<li>In pgsql/src/backend/parser/parse_param.c, make fixed_paramref_hook behave properly when there are 'unused' slots in the parameter array. Noted while experimenting with an example from Pavel Stehule. This wouldn't come up in normal use, but it ought to honor the specification that a parameter array can have unused slots.</li>
<li>In pgsql/src/backend/utils/cache/plancache.c, fix bug #5269: ResetPlanCache mustn't invalidate cached utility statements, especially not ROLLBACK. ROLLBACK might need to be executed in an already aborted transaction, when there is no safe way to revalidate the plan. But in general there's no point in marking utility statements invalid, since they have no plans in the normal sense of the word; so we might as well work a bit harder here to avoid future revalidation cycles. Back-patch to 8.4, where the bug was introduced.</li>
<li>In pgsql/src/backend/utils/cache/relcache.c, when loading critical system indexes into the relcache, ensure we lock the underlying catalog not only the index itself. Otherwise, if the cache load process touches the catalog (which will happen for many though not all of these indexes), we are locking index before parent table, which can result in a deadlock against processes that are trying to lock them in the normal order. Per today's failure on buildfarm member gothic_moth; it's surprising the problem hadn't been identified before. Back-patch to 8.2. Earlier releases didn't have the issue because they didn't try to lock these indexes during load (instead assuming that they couldn't change schema at all during multiuser operation).</li>
<li>In pgsql/src/port/exec.c, simplify validate_exec() by using access(2) to check file permissions, rather than trying to implement the equivalent logic by hand. The motivation for the original coding appears to have been to check with the effective uid's permissions not the real uid's; but there is no longer any difference, because we don't run the postmaster setuid (indeed, main.c enforces that they're the same). Using access() means we will get it right in situations the original coding failed to handle, such as ACL-based permissions. Besides it's a lot shorter, cleaner, and more thread-safe. Per bug #5275 from James Bellinger.</li>
<li>In pgsql/src/backend/replication/walreceiver/Makefile, fix bogus subdir setting ... wonder just what that affects ...</li>
<li>In pgsql/src/backend/replication/walreceiver/Makefile, actually, I'll bet the mingw problem is lack of $(BE_DLLLIBS) ...</li>
<li>In pgsql/src/backend/replication/walreceiver/Makefile, no, scratch that, it was getting added twice.</li>
<li>Second try: walreceiver should not be built with -DBUILDING_DLL</li>
<li>Do parse analysis of an EXPLAIN's contained statement during the normal parse analysis phase, rather than at execution time. This makes parameter handling work the same as it does in ordinary plannable queries, and in particular fixes the incompatibility that Pavel pointed out with plpgsql's new handling of variable references. plancache.c gets a little bit grottier, but the alternatives seem worse.</li>
<li>PGDLLIMPORT-ize the remaining variables needed by walreceiver.</li>
<li>In pgsql/src/include/libpq/pqsignal.h, huh, apparently on cygwin we HAVE_SIGPROCMASK, so both variants of the BlockSig/UnBlockSig declaration have to be PGDLLIMPORT'ified. Per buildfarm results.</li>
<li>In pgsql/src/backend/storage/ipc/procarray.c, fix bogus initialization of KnownAssignedXids shared memory state --- didn't work in EXEC_BACKEND case.</li>
<li>In pgsql/src/backend/parser/scan.l, fix unportable use of isxdigit() with char (rather than unsigned char) argument, per warnings from buildfarm member pika. Also clean up code formatting a trifle.</li>
<li>Re-order configure tests to reflect the fact that the code generated for posix_fadvise and other file-related functions can depend on _LARGEFILE_SOURCE and/or _FILE_OFFSET_BITS. Per report from Robert Treat. Back-patch to 8.4. This has been wrong all along, but we weren't really using posix_fadvise in anger before, and AC_FUNC_FSEEKO seems to mask the issue well enough for that function.</li>
<li>In pgsql/src/backend/tcop/postgres.c, remove unnecessary, inconsistent flag resets in ProcessInterrupts.</li>
<li>Improve the handling of SET CONSTRAINTS commands by having them search pg_constraint before searching pg_trigger. This allows saner handling of corner cases; in particular we now say "constraint is not deferrable" rather than "constraint does not exist" when the command is applied to a constraint that's inherently non-deferrable. Per a gripe several months ago from hubert depesz lubaczewski. To make this work without breaking user-defined constraint triggers, we have to add entries for them to pg_constraint. However, in return we can remove the pgconstrname column from pg_constraint, which represents a fairly sizable space savings. I also replaced the tgisconstraint column with tgisinternal; the old meaning of tgisconstraint can now be had by testing for nonzero tgconstraint, while there is no other way to get the old meaning of nonzero tgconstraint, namely that the trigger was internally generated rather than being user-created. In passing, fix an old misstatement in the docs and comments, namely that pg_trigger.tgdeferrable is exactly redundant with pg_constraint.condeferrable. Actually, we mark RI action triggers as nondeferrable even when they belong to a nominally deferrable FK constraint. The SET CONSTRAINTS code now relies on that instead of hard-coding a list of exception OIDs.</li>
<li>In pgsql/doc/src/sgml/ref/set_constraints.sgml, update SET CONSTRAINTS reference page --- it failed to mention EXCLUDE constraints and was lacking a couple of other interesting details.</li>
<li>In pgsql/src/backend/utils/mmgr/portalmem.c, fix portalmem.c to avoid keeping a dangling pointer to a cached plan list after it's released its reference count for the cached plan. There are code paths that might try to examine the plan list before noticing that the portal is already in aborted state. Report and diagnosis by Tatsuo Ishii, though this isn't exactly his proposed patch.</li>
</ul>
<p>Bruce Momjian a commit&eacute;&nbsp;:</p>
<ul>
<li>In pgsql/doc/src/sgml/backup.sgml, remove tabs in SGML file.</li>
<li>Place tablespace directories in their own subdirectory so pg_migrator can upgrade clusters without renaming the tablespace directories. New directory structure format is, e.g.: $PGDATA/pg_tblspc/20981/PG_8.5_201001061/719849/83292814</li>
<li>In src/backend/replication/walreceiver/walreceiver.c, add #include &lt;sys/time.h&gt;gt; for struct timeval definition on BSD/OS.</li>
</ul>
<p>Michael Meskes a commit&eacute;&nbsp;:</p>
<ul>
<li>In pgsql/src/interfaces/ecpg/ecpglib/typename.c, applied Zoltan Boszormenyi's patch to make char the default sqlda type. Given that undefined types are handled as character strings anyway the type translation function can simply return the correcponding ECPGt_char type.</li>
<li>Applied patch by Zoltan Boszormenyi to add DESCRIBE [OUTPUT] statement to ecpg.</li>
<li>In pgsql/src/interfaces/ecpg/ecpglib/descriptor.c, added correct error handling in DESCRIBE statement processing by Zoltan Boszormenyi.</li>
<li>Modified Files: --------------</li>
<li>Removed ecpg Changelog file that was only there for historical reasons and isn't actively used anymore.</li>
<li>Fix SQL3 type return value. For non-SQL3 types ecpg used to return -Oid. This will break if there are enough Oids to fill the namespace. Therefore we play it safe and return 0 if there is no Oid-&gt;gt;SQL3 tyoe mapping available.</li>
</ul>
<p>Magnus Hagander a commit&eacute;&nbsp;:</p>
<ul>
<li>In pgsql/doc/src/sgml/install-win32.sgml, update MSVC build instructions. Updated to reflect building with Visual Studio 2008, with just the Platform SDK, and for 64-bit Windows.</li>
<li>In pgsql/src/tools/msvc/Mkvcbuild.pm, build the walreceiver library on MSVC as well.</li>
<li>In pgsql/doc/src/sgml/installation.sgml, fix spelling error, noticed by Thomas Shinnick.</li>
<li>In pgsql/contrib/xml2/xpath.c, silence compiler warning, noted by Stefan Kaltenbrunner</li>
<li>In pgsql/src/tools/msvc/Mkvcbuild.pm, add include directory for dblink to find fmgroids.h on VS2008 builds.</li>
</ul>
<p>Simon Riggs a commit&eacute;&nbsp;:</p>
<ul>
<li>First part of refactoring of code for ResolveRecoveryConflict. Purposes of this are to centralise the conflict code to allow further change, as well as to allow passing through the full reason for the conflict through to the conflicting backends. Backend state alters how we can handle different types of conflict so this is now required. As originally suggested by Heikki, no longer optional.</li>
<li>Teach standby conflict resolution to use SIGUSR1. Conflict reason is passed through directly to the backend, so we can take decisions about the effect of the conflict based upon the local state. No specific changes, as yet, though this prepares for later work. CancelVirtualTransaction() sends signals while holding ProcArrayLock. Introduce errdetail_abort() to give message detail explaining that the abort was caused by conflict processing. Remove CONFLICT_MODE states in favour of using PROCSIG_RECOVERY_CONFLICT states directly, for clarity.</li>
<li>In pgsql/src/backend/storage/ipc/standby.c, message mentions msec when it should be seconds, so use s instead of ms. Noticed by Andres Freund.</li>
<li>In pgsql/src/backend/commands/dbcommands.c, lock database while running drop database in Hot Standby to protect against concurrent reconnection. Failure during testing showed issue was possible, even though earlier analysis seemed to indicate it would not be required. Use LockSharedObjectForSession() before ResolveRecoveryConflictWithDatabase() and hold lock until end of processing for that WAL record. Simple approach to avoid introducing further bugs at this stage of development on an improbable issue.</li>
</ul>
<p>Teodor Sigaev a commit&eacute;&nbsp;:</p>
<ul>
<li>Add point_ops opclass for GiST.</li>
</ul>
<p>Heikki Linnakangas a commit&eacute;&nbsp;:</p>
<ul>
<li>Introduce Streaming Replication. This includes two new kinds of postmaster processes, walsenders and walreceiver. Walreceiver is responsible for connecting to the primary server and streaming WAL to disk, while walsender runs in the primary server and streams WAL from disk to the client. Documentation still needs work, but the basics are there. We will probably pull the replication section to a new chapter later on, as well as the sections describing file-based replication. But let's do that as a separate patch, so that it's easier to see what has been added/changed. This patch also adds a new section to the chapter about FE/BE protocol, documenting the protocol used by walsender/walreceivxer. Bump catalog version because of two new functions, pg_last_xlog_receive_location() and pg_last_xlog_replay_location(), for monitoring the progress of replication. Fujii Masao, with additional hacking by Heikki Linnakangas.</li>
<li>In pgsql/src/backend/replication/walsender.c, remove unused (in non-assertion-enabled build) variable.</li>
<li>In pgsql/src/Makefile, move build of src/backend/replication/walreceiver/ later in the build process, after src/interfaces, because it depends on libpq. Also add missing lines for clean, etc. targets. Report from Zoltan Boszormenyi.</li>
</ul>
<p>Peter Eisentraut a commit&eacute;&nbsp;:</p>
<ul>
<li>Improved printing of Python exceptions in PL/Python. Mimic the Python interpreter's own logic for printing exceptions instead of just using the straight str() call, so that you get plpy.SPIError instead of &lt;class 'plpy.SPIError'&gt;gt; and for built-in exceptions merely, UnicodeEncodeError. Besides looking better this cuts down on the endless version differences in the regression test expected files.</li>
