* Correct bogus mktime() calls.Tom Lane2001-04-03
|
* Check for failure of malloc() and realloc() when allocating space forTom Lane2001-04-03
| | | | | | VFD entries. On platforms where dereferencing a null pointer doesn't lead to coredump, it's possible that this omission could have led to unpleasant behavior like deleting the wrong file.
* open(2) flags saved for re-opening a virtual file should probably notTom Lane2001-04-03
| | | | include O_CREAT.
* Restore pre-7.1 behavior of allowing DROP of a table whose underlyingTom Lane2001-04-02
| | | | | | physical file has disappeared. There is no really good reason why relcache should be opening the underlying file at all, AFAICS. In any case we needn't raise a hard error here.
* _mdfd_getrelnfd() should include kernel error code in failure message.Tom Lane2001-04-02
|
* Complain if the same column name is inherited from multiple parentsTom Lane2001-04-02
| | | | | | with different default values, unless the child table redeclares the column with an explicit default. This was judged to be the approach least likely to cause unpleasant surprises.
* Disable creation of indexes on system tables.Bruce Momjian2001-04-02
|
* Remove duplicate definition of DLLLIBS, per gripe from Fred Yankowski.Tom Lane2001-04-02
|
* Tom Ivar Helbekkmo <tih@kpnQwest.no> says that dynamic linking worksTom Lane2001-04-02
| | | | now on VAX NetBSD. Hence, remove #ifdef'd disable tests.
* Planner wasn't correctly handling adjustment of tuple_fraction for theTom Lane2001-04-01
| | | | case of LIMIT in a sub-select.
* Re-allow specification of a new default value for an inherited columnTom Lane2001-03-30
| | | | | | in CREATE TABLE, but give a warning notice. Clean up inconsistent handling of defaults and NOT NULL flags from multiply-inherited columns. Per pghackers discussion 28-Mar through 30-Mar.
* Rename 'random_seed' back to 'seed'.Peter Eisentraut2001-03-29
|
* Quick hack to fix Oliver Elphick's problem with subselects in anTom Lane2001-03-27
| | | | | | | inheritance query: make duplicate copies of subplans in adjust_inherited_attrs. When we redesign querytrees we really gotta do something about this issue of whether querytrees are read-only and can share substructure or not.
* Repair pgindent damage to comments.Tom Lane2001-03-27
|
* The following patch updates the FAQ_AIX and makes C++ code work withBruce Momjian2001-03-27
| | | | | | | | | | | | | | | | | | more recent versions of the IBM C++ compiler (now called VisualAge C++). The C++ part was previously broken (g++ and xlC), thus this is zero risk. Only AIX specific parts are touched (1 Makefile.shlib line (link with $(COMPILER ) instead of $(CC) and one shell script line (parameter -C to nm to not demangle C++ symbo ls for .exp file)). I thus ask you to please apply this patch before release. With or without this patch RC1 on AIX 4.3.2 RS6000 passes "gmake check" for both the native compiler vac.C 5.0.1 and gcc 2.95.2 :-) Andreas
* Spell __volatile__ correctly.Tom Lane2001-03-27
|
* Add period to message.Bruce Momjian2001-03-26
|
* Change message to _the_ administrator. There is only one administrativeBruce Momjian2001-03-26
| | | | | | account. This connection has been terminated by the administrator.
* Fix unportable assumptions about alignment of local char[n] variables.Tom Lane2001-03-25
|
* Fix code that incorrectly assumed a 'char foo[N]' local variable wouldTom Lane2001-03-25
| | | | be aligned on a word boundary. Per report from Steve Nicolai.
* When using 'long long int' for int64 type, check to see if the compilerTom Lane2001-03-23
| | | | | | accepts nnnLL syntax for long long constants. If so, decorate the CRC64 constants with LL to avoid warnings and/or erroneous results from certain non-standards-compliant compilers.
* Mark exception and assert global variables as DLLIMPORT, so that plpgsqlTom Lane2001-03-23
| | | | can be compiled with asserts enabled on Windoze.
* Fix comments that were mis-wrapped, for Tom Lane.Bruce Momjian2001-03-23
|
* Fix Joubert's complaint that int8-sized numeric literals are mishandledTom Lane2001-03-22
| | | | | | | | | on Alpha (because parser mistakenly assumes that a nonoverflow result from strtol means the value will fit into int4). A scan for other uses of strtol and strtoul found a couple other places with the same mistake; fix them too. The changes are all conditional on HAVE_LONG_INT_64 to avoid complaints from compilers that think x != x is a silly test (cf. pg_atoi).
* Remove dashes in comments that don't need them, rewrap with pgindent.Bruce Momjian2001-03-22
|
* pgindent run. Make it all clean.Bruce Momjian2001-03-22
|
* Check bufHdr->cntxDirty and call StartBufferIO in BufferSync()Vadim B. Mikheev2001-03-21
| | | | | | | | *before* acquiring shlock on buffer context. This way we should be protected against conflicts with FlushRelationBuffers. (Seems we never do excl lock and then StartBufferIO for the same buffer, so there should be no deadlock here, - but we'd better check this very soon).
* Fix 'ps' WAIT status display bug on setproctitle() platforms, cleared byBruce Momjian2001-03-20
| | | | Tom Lane.
* Tweak out-of-memory error messages to include the request size, so thatTom Lane2001-03-19
| | | | | it's easier to tell whether a bug report is talking about progressive memory exhaustion or a wacko requested chunk size.
* Make regular-expression error messages a tad less obscure,Tom Lane2001-03-19
| | | | per gripe from Josh Berkus.
* Remove NEXTXID xlog record type to avoid three-way deadlock risk.Tom Lane2001-03-18
| | | | | NEXTXID isn't really necessary, per previous discussion in pghackers, but I mulishy insisted we should put it in anyway. Mea culpa.
* When we add 'waiting' to the ps_status display, there should be aTom Lane2001-03-18
| | | | space in front of it. Improve comments a little.
* Considering the BeOS port didn't compile without IPC_STAT and shm_nattch,Tom Lane2001-03-18
| | | | I'm betting the QNX4 port does not either ...
* Patches from Cyril Velter to make shared-memory-conflict-detection codeTom Lane2001-03-18
| | | | work in BeOS port.
* Make sure ControlFile logId/logSeg don't go backwards (barely possible given aTom Lane2001-03-18
| | | | slow backend, if we update unconditionally as the code did before).
* Rearrange XLogFileInit so that control-file spinlock is not held while fillingTom Lane2001-03-17
| | | | | the new log file with zeroes, only while renaming it into place. This should prevent problems with 'stuck spinlock' errors under heavy load.
* Support syncing WAL log to disk using either fsync(), fdatasync(),Tom Lane2001-03-16
| | | | | | | | O_SYNC, or O_DSYNC (as available on a given platform). Add GUC parameter to control sync method. Also, add defense to XLogWrite to prevent it from going nuts if passed a target write position that's past the end of the buffers so far filled by XLogInsert.
* Give a more reasonable error message for a bad attribute name appliedTom Lane2001-03-14
| | | | to a join or subselect alias ... cf. Oliver Elphick's complaint 13-Mar.
* Reduce amount of memory used per tuple for after-event triggers. ThisTom Lane2001-03-14
| | | | is still a memory leak, but a little less bad than it was.
* COPY should handle after-insert triggers the same as execMain.c does.Tom Lane2001-03-14
| | | | | | I'm not sure that it's really necessary to save insert events when there are only after update or delete triggers, but certainly it's wrong for COPY to behave differently from an INSERT query.
* Use SEP_CHAR consistently in forming XLOG pathnames.Tom Lane2001-03-14
|
* Remove obsolete PowerPC-specific hack for comparisons to DBL_MINTom Lane2001-03-14
| | | | | (per recent discussion with Tatsuo). Hopefully the compilers with that old bug are all long gone.
* 'waiting' status display had extra space, removed.Bruce Momjian2001-03-14
| | | | Change the administrator to 'an' administrator.
* Don't go belly-up if fork() fails for a routine checkpoint subprocess.Tom Lane2001-03-14
| | | | Just try again later.
* Fix numeric modulo operator for case of fractional right argument.Tom Lane2001-03-14
|
* New shutdown wording:Bruce Momjian2001-03-14
| | | | This connection has been terminated by the administrator
* ifdef out reindex stuff in VACUUM for safety.Hiroshi Inoue2001-03-14
|
* Change xlog page-header format to include StartUpID. Use the SUI toTom Lane2001-03-13
| | | | | | | | | detect case that next page in log came from an older run than the prior page. This avoids the necessity to re-zero the log after recovery from a crash, which is good because we need not risk destroying valuable log information. This forces another initdb since yesterday :-(. Need to get that log reset utility done...
* XLOG (and related) changes:Tom Lane2001-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Store two past checkpoint locations, not just one, in pg_control. On startup, we fall back to the older checkpoint if the newer one is unreadable. Also, a physical copy of the newest checkpoint record is kept in pg_control for possible use in disaster recovery (ie, complete loss of pg_xlog). Also add a version number for pg_control itself. Remove archdir from pg_control; it ought to be a GUC parameter, not a special case (not that it's implemented yet anyway). * Suppress successive checkpoint records when nothing has been entered in the WAL log since the last one. This is not so much to avoid I/O as to make it actually useful to keep track of the last two checkpoints. If the things are right next to each other then there's not a lot of redundancy gained... * Change CRC scheme to a true 64-bit CRC, not a pair of 32-bit CRCs on alternate bytes. Polynomial borrowed from ECMA DLT1 standard. * Fix XLOG record length handling so that it will work at BLCKSZ = 32k. * Change XID allocation to work more like OID allocation. (This is of dubious necessity, but I think it's a good idea anyway.) * Fix a number of minor bugs, such as off-by-one logic for XLOG file wraparound at the 4 gig mark. * Add documentation and clean up some coding infelicities; move file format declarations out to include files where planned contrib utilities can get at them. * Checkpoint will now occur every CHECKPOINT_SEGMENTS log segments or every CHECKPOINT_TIMEOUT seconds, whichever comes first. It is also possible to force a checkpoint by sending SIGUSR1 to the postmaster (undocumented feature...) * Defend against kill -9 postmaster by storing shmem block's key and ID in postmaster.pid lockfile, and checking at startup to ensure that no processes are still connected to old shmem block (if it still exists). * Switch backends to accept SIGQUIT rather than SIGUSR1 for emergency stop, for symmetry with postmaster and xlog utilities. Clean up signal handling in bootstrap.c so that xlog utilities launched by postmaster will react to signals better. * Standalone bootstrap now grabs lockfile in target directory, as added insurance against running it in parallel with live postmaster.
* Avoid O(N^2) behavior in deferredTriggerAddEvent() for large numbers ofTom Lane2001-03-12
