* Change s_lock to not use any zero-delay select() calls; these are just aTom Lane2001-02-18
| | | | | | | | | | waste of cycles on single-CPU machines, and of dubious utility on multi-CPU machines too. Tweak s_lock_stuck so that caller can specify timeout interval, and increase interval before declaring stuck spinlock for buffer locks and XLOG locks. On systems that have fdatasync(), use that rather than fsync() to sync WAL log writes. Ensure that WAL file is entirely allocated during XLogFileInit.
* Remove bogus set_ps_display call --- changing displayed status here isTom Lane2001-02-18
| | | | | | either wrong or unnecessary in most cases, and on systems where setting status takes a kernel call, the overhead of setting status three times per command rather than two is annoying.

* Some more updates...Peter Mount2001-02-16
| | | | | | | | | | | | | Fri Feb 17 15:11:00 GMT 2001 peter@retep.org.uk - Reduced the object overhead in PreparedStatement by reusing the same StringBuffer object throughout. Similarly SimpleDateStamp's are alse reused in a thread save manner. - Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp using Calendar, setBlob(), setCharacterStream() - Clob's are now implemented in ResultSet & PreparedStatement! - Implemented a lot of DatabaseMetaData & ResultSetMetaData methods. We have about 18 unimplemented methods left in JDBC2 at the current time.

* Fix bugs in pltcl's new return_null command: it was liable to go belly upTom Lane2001-02-16
| | | | | | | if the return datatype's input converter was at all strict, because the converter would get called on junk data when returning NULL. Also ensure that it gives an error rather than coredumping if someone tries to use it in a trigger function.
* Fix erroneous sort request in pltcl selftest.Tom Lane2001-02-16

* Clean up two rather nasty bugs in operator selection code.Tom Lane2001-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. If there is exactly one pg_operator entry of the right name and oprkind, oper() and related routines would return that entry whether its input type had anything to do with the request or not. This is just premature optimization: we shouldn't return the single candidate until after we verify that it really is a valid candidate, ie, is at least coercion-compatible with the given types. 2. oper() and related routines only promise a coercion-compatible result. Unfortunately, there were quite a few callers that assumed the returned operator is binary-compatible with the given datatype; they would proceed to call it without making any datatype coercions. These callers include sorting, grouping, aggregation, and VACUUM ANALYZE. In general I think it is appropriate for these callers to require an exact or binary-compatible match, so I've added a new routine compatible_oper() that only succeeds if it can find an operator that doesn't require any run-time conversions. Callers now call oper() or compatible_oper() depending on whether they are prepared to deal with type conversion or not. The upshot of these bugs is revealed by the following silliness in PL/Tcl's selftest: it creates an operator @< on int4, and then tries to use it to sort a char(N) column. The system would let it do that :-( (and evidently has done so since 6.3 :-( :-(). The result in this case was just a silly sort order, but the reverse combination would've provoked coredump from trying to dereference integers. With this fix you get more reasonable behavior: pltcl_test=# select * from T_pkey1 order by key1, key2 using @<; ERROR: Unable to identify an operator '@<' for types 'bpchar' and 'bpchar' You will have to retype this query using an explicit cast
* Add casting for numeric/float4/float8 type valueHiroshi Inoue2001-02-16
| | | | | | | | | | | automatically to compensate the lack of automatic conversion functionality of PostgreSQL server. For example if there's a numeric type binding 1.2567 --> 1.2567::numeric. I hope this change would enable the use of numeric type in MS-Access etc. Thanks Hiroki Kataoka for his checking my code.
* Take OUTER JOIN semantics into account when estimating the size of joinTom Lane2001-02-16
| | | | | relations. It's not very bright, but at least it now knows that A LEFT JOIN B must produce at least as many rows as are in A ...

* Although we can't support out-of-line TOAST storage in indexes (yet),Tom Lane2001-02-15
| | | | | | | | compressed storage works perfectly well. Might as well have a coherent strategy for applying it, rather than the haphazard store-what-you-get approach that was in the code before. The strategy I've set up here is to attempt compression of any compressible index value exceeding BLCKSZ/16, or about 500 bytes by default.
* Reduce default selectivity estimates for geometric operators; it seemsTom Lane2001-02-15
| | | | | | | the old ones were not small enough to ensure r-tree and gist indexes would get picked when available. These numbers are totally bogus anyway, but in the absence of any real estimation technique, we'd like to select indexes when available ...
* Update a couple of obsolete comments.Tom Lane2001-02-15

* 1) Change transaction boundary in autocommit off modeHiroshi Inoue2001-02-15
| | | | | | | | | | per recent discussion in pgsql-odbc. Now SELECT is a boundary but VACUUM isn't. 2) Put back the error handling behavior. When elog(ERROR) was detected the driver automatically issue "ABORT" if a transaction is in progress. 3) Driver version is 7.01.0003(Dave already set it but it was put back).

* Arrange for ORDER BY an expression on a UNION/INTERSECT/EXCEPT result,Tom Lane2001-02-15
| | | | | | | | | | such as SELECT f1 FROM foo UNION SELECT ... ORDER BY upper(f1) to draw 'ORDER BY on a UNION/INTERSECT/EXCEPT result must be on one of the result columns' rather than the uninformative 'f1 not found' we were producing before. Eventually this should actually work, but that looks much too hard to try to implement in late beta...
* Repair problems with duplicate index names generated when CREATE TABLETom Lane2001-02-14
| | | | specifies redundant UNIQUE conditions.
* Change scoping of table and join refnames to conform to SQL92: a JOINTom Lane2001-02-14
| | | | | | | | | clause with an alias is a <subquery> and therefore hides table references appearing within it, according to the spec. This is the same as the preliminary patch I posted to pgsql-patches yesterday, plus some really grotty code in ruleutils.c to reverse-list a query tree with the correct alias name depending on context. I'd rather not have done that, but unless we want to force another initdb for 7.1, there's no other way for now.

* Comments about GetFreeXLBuffer().Vadim B. Mikheev2001-02-13
| | | | | GetFreeXLBuffer(): use Insert->LgwrResult instead of private LgwrResult copy if it's more fresh (attempt to avoid acquiring info_lck/lgwr_lck).
* Some more including the patch to DatabaseMetaData backed out by Bruce.Peter Mount2001-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk - More TestCases implemented. Refined the test suite api's. - Removed need for SimpleDateFormat in ResultSet.getDate() improving performance. - Rewrote ResultSet.getTime() so that it uses JDK api's better. Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk - Added MiscTest to hold reported problems from users. - Fixed PGMoney. - JBuilder4/JDBCExplorer now works with Money fields. Patched Field & ResultSet (lots of methods) for this one. Also changed cash/money to return type DOUBLE not DECIMAL. This broke JBuilder as zero scale BigDecimal's can't have decimal places! - When a Statement is reused, the previous ResultSet is now closed. - Removed deprecated call in ResultSet.getTime() Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk - Changed a couple of settings in DatabaseMetaData where 7.1 now supports those features - Implemented the DatabaseMetaData TestCase. Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk - Added comment to Connection.isClosed() explaining why we deviate from the JDBC2 specification. - Fixed bug where the Isolation Level is lost while in autocommit mode. - Fixed bug where several calls to getTransactionIsolationLevel() returned the first call's result.
