* Remove gratuitous and incorrect begin/commit transaction calls inTom Lane2000-03-15
| | | | | | | | CREATE DB/DROP DB. If you didn't think they were wrong, try what happens when you compile with -DCLOBBER_FREED_MEMORY --- database name displayed in error messages is trashed, because transaction abort freed it. Also, remove trailing periods in error messages, per our prevailing style.
* Fix a couple of missed changes in expected results.Tom Lane2000-03-15

* Add 'datetime' -> 'timestamp' conversion to xlateSqlFunc() to easeTom Lane2000-03-15
| | | | | the pain of updating apps to 7.0. Should we also translate some of the 'datetime_foo' functions that exist in 6.* ?

|
* Cache fmgr lookup data for index's getnext() function in IndexScanDesc,Tom Lane2000-03-14
| | | | | so that the fmgr lookup only has to happen once per index scan and not once per tuple. Seems to save 5% or so of CPU time for an indexscan.
* Implement column aliases on views "CREATE VIEW name (collist)".Thomas G. Lockhart2000-03-14
| | | | | | | | | | | | | | | | | | Implement TIME WITH TIME ZONE type (timetz internal type). Remap length() for character strings to CHAR_LENGTH() for SQL92 and to remove the ambiguity with geometric length() functions. Keep length() for character strings for backward compatibility. Shrink stored views by removing internal column name list from visible rte. Implement min(), max() for time and timetz data types. Implement conversion of TIME to INTERVAL. Implement abs(), mod(), fac() for the int8 data type. Rename some math functions to generic names: round(), sqrt(), cbrt(), pow(), etc. Rename NUMERIC power() function to pow(). Fix int2 factorial to calculate result in int4. Enhance the Oracle compatibility function translate() to work with string arguments (from Edwin Ramirez). Modify pg_proc system table to remove OID holes.

* Marginal performance improvement in LockBuffer --- calculate addressTom Lane2000-03-14
| | | | | | of BufferLocks[] entry just once. Seems to save 10% or so of the routine's runtime, which'd not be worth worrying about if it weren't such a hotspot.

* Detect postmaster being ready by calling psql -l rathern thanTatsuo Ishii2000-03-14
| | | | | checking postmaster.pid. It's not enough to check the existence of postmaster.pid since DB recovery might be running.
* Fix some bogosities in the code that deals with estimating the fractionTom Lane2000-03-14
| | | | | of tuples we are going to retrieve from a sub-SELECT. Must have been half asleep when I did this code the first time :-(
* Fixed deficiency where an unterminated (no semicolon) command at end ofPeter Eisentraut2000-03-13
| | | | psql script would be dropped silently.
* Extend numeric_round and numeric_trunc to accept negative scale inputsTom Lane2000-03-13
| | | | | | (ie, allow rounding to occur at a digit position left of the decimal point). Apparently this is how Oracle handles it, and there are precedents in other programming languages as well.
* Remove unnecessary limitations on lengths of bpchar and varchar constants.Tom Lane2000-03-13
| | | | | | Since we detect oversize tuples elsewhere, I see no reason not to allow string constants that are 'too long' --- after all, they might never get stored in a tuple at all.
* Performance improvement for lexing long strings: increase flex'sTom Lane2000-03-13
| | | | | | YY_READ_BUF_SIZE, which turns out to have nothing to do with buffer size. It's just a totally arbitrary upper limit on how much data myinput() is asked for at one time.
* Somehow, the variant NATIONAL CHAR [ VARYING ] was missing from theTom Lane2000-03-12
| | | | set of SQL-standard type names that we accept.
* Fix performance bug in constant-expression simplifier. After findingTom Lane2000-03-12
| | | | | | | | | that the inputs to a given operator can be recursively simplified to constants, it was evaluating the operator using the op's *original* (unsimplified) arg list, so that any subexpressions had to be evaluated again. A constant subexpression at depth N got evaluated N times. Probably not very important in practical situations, but it made us look real slow in MySQL's 'crashme' test...
* Fix performance problem in fireRIRonSubselect: with nested subqueries,Tom Lane2000-03-12
| | | | | fireRIRonSubselect was invoked twice at each subselect, leading to an exponential amount of wasted effort.
* Clean up grammar's handling of NULL in expressions: a_expr_or_null isTom Lane2000-03-12
| | | | | | | gone, replaced by plain a_expr. The few places where we needed to distinguish NULL from a_expr are now handled by tests inside the actions rather than by separate productions. This allows us to accept queries like 'SELECT 1 + NULL' without requiring parentheses around the NULL.
* Further tweaking of logic that decides when to materialize an uncorrelatedTom Lane2000-03-11
| | | | | | | subplan: do it if subplan has subplans itself, and always do it if the subplan is an indexscan. (I originally set it to materialize an indexscan only if the indexqual is fairly selective, but I dunno what I was thinking ... an unselective indexscan is still expensive ...)
* Make TypeCategory think that NAME is a member of typeTom Lane2000-03-11
| | | | | category STRING. Also, if UNKNOWNOID is passed in, return UNKNOWN_TYPE not USER_TYPE.
* Further fixes for bogus list-slinging, scribbling on input, etc in typeTom Lane2000-03-11
| | | | | | | | | coercion code. I'm beginning to wonder why we have separate candidate selection routines for functions, operators, and aggregates --- shouldn't this code all be unified? But meanwhile, SELECT 'a' LIKE 'a'; finally works; the code for dealing with unknown input types for operators was pretty busted.
* Karel Zakr's revised patch to fix psql prompt for local host connections.Peter Eisentraut2000-03-11

* exec_simple_check_plan() must not allow a plan having initPlans orTom Lane2000-03-11
| | | | | subPlans to be considered 'simple'. This fixes reported problem with 'return exists (select 1 from foo);' in plpgsql function.
* Finish cleaning up backend's handling of /* ... */ and -- comments,Tom Lane2000-03-11
| | | | | | | per pghackers discussion around 20-Feb. Also add specific error messages for unterminated comments and unterminated quoted strings. These things are nonissues for input coming from psql, but they do matter for input coming from other front ends.
* Update libpq documentation for PQconndefaults() change. Add sectionTom Lane2000-03-11
| | | | about thread-safeness of the library.
* Change PQconndefaults() to return a malloc'd array, instead of a staticTom Lane2000-03-11
| | | | | | | | array. This allows processing of conninfo strings to be made thread-safe, at the cost of a small memory leak in applications that use PQconndefaults() and are not updated to free the returned array via the new PQconninfoFree() function. But PQconndefaults() is probably not used very much, so this seems like a good compromise.

* Hi,Bruce Momjian2000-03-08
| | | | | | | | | The regression test script runcheck.sh doesn't seem able to handle the blank line on the end of the resultmap file. Here's a patch to remove it!! Keith.
* I've made a diff against the 7.0beta1 tree that accomplishes several things:Bruce Momjian2000-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) adds NetBSD shared lib support on both ELF and a.out platforms 2) replaces "-L$(LIBPQDIR) -lpq" with "$(LIBPQ)" defined in Makefile.global. This makes it much easier to build stuff in the source tree after you've already installed the libraries. 3) adds TEMPLATEDIR in Makefile.global that indicates where the database templates are stored. This separates the template files from real libraries that are installed in $(LIBDIR). 4) changes include order of <readline/readline.h> and <readline.h>. The latest GNU readline installs its headers under a readline subdirectory. In addition to applying the patch below the following files need to be copied: backend/port/dynloader: bsd.h -> netbsd.h bsd.c -> netbsd.c include/port: bsd.h -> netbsd.h makefiles: Makefile.bsd -> Makefile.netbsd It would be great to see this incorporated into the source tree before the 7.0 release is cut. Thanks! -- Johnny C. Lam <lamj@stat.cmu.edu>
* Bruce and all:Bruce Momjian2000-03-08
| | | | | | | | | | Here's a patch to fix the " '.' not allowed in db path" problem I ran into. I removed '.' from the set of illegial characters, but added backtick. I also included an explicit test for attempting include a reference to a parent dir. How that? Ross
