caa6fc1ba2 Add translation of timespan to interval. 2000-03-18 00:33:45 +00:00
3faa9bab07 Patch possible portability problem: a few places had // style comments,
which is not ANSI C, even though some compilers will take it...

64ef5c82de Typo correction (// -> /) 2000-03-17 23:17:23 +00:00
0e314d747e Add safety check on expression nesting depth. Default value is set by
a config.h #define, and the runtime value can be controlled via SET.

341b328b18 Fix a bunch of minor portability problems and maybe-bugs revealed by
running gcc and HP's cc with warnings cranked way up.  Signed vs unsigned
comparisons, routines declared static and then defined not-static,
that kind of thing.  Tedious, but perhaps useful...

3e4708c45c libpq++ Makefile uses -DDEBUG to turn on debugging trace to
/tmp/trace.out.
However, elog.h uses DEBUG as a log-level flag.  As a result, tracing is
turned on even if the libpq++.so is built with DEBUG commented out in
the Makefile.

This patch changes libpq++ to use DEBUGFILE instead (which is not
defined anywhere else).

d14c8aab99 Turns out that Mazurkiewicz's gripe about 'function inheritance' is
actually a type-coercion problem.  If you have a function defined on
class A, and class B inherits from A, then the function ought to work
on class B as well --- but coerce_type didn't know that.  Now it does.

e64a331179 Fix some (more) problems with subselects in rules. Rewriter failed to
mark query as having subselects if a subselect was added from a rule
WHERE condition (as opposed to a rule action).  Also, fix adjustment
of varlevelsup so that it actually has some prospect of working when
inserting an expression containing a subselect into a subquery.

4a3a1e2cf1 Hi,
small changes in formatting.c code (better memory usage ...etc.) and
better
to_char's cache (will fastly for more to_char()s in one query).

(It is probably end of to_char() development in 7.0 cycle.)

6358e654ca Update comment obsoleted by Thomas's latest fixes. 2000-03-15 23:42:14 +00:00
1763a7c1ea Tweak GROUP BY so that it will still accept result-column names, but only
after trying to resolve the item as an input-column name.  This allows us
to be compliant with the SQL92 spec for queries that fall within the spec,
while still accepting the same out-of-spec queries as 6.5 did.  You'll only
lose if there is an output column name that is the same as an input
column name, but doesn't refer to the same value.  7.0 will interpret
such a GROUP BY spec differently than 6.5 did.  No way around that, because
6.5 was clearly not spec compliant.

84b9507f78 Remove another incorrect UserAbortTransactionBlock() call. 2000-03-15 07:02:56 +00:00
fe189063b8 Remove gratuitous and incorrect begin/commit transaction calls in
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.

ce3b489b97 Add 'datetime' -> 'timestamp' conversion to xlateSqlFunc() to ease
the pain of updating apps to 7.0.  Should we also translate some of
the 'datetime_foo' functions that exist in 6.* ?

34235a295b Cache fmgr lookup data for index's getnext() function in IndexScanDesc,
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.

6456810078 Implement column aliases on views "CREATE VIEW name (collist)".
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.

c40a0a1b52 Marginal performance improvement in LockBuffer --- calculate address
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.

44a9639123 Detect postmaster being ready by calling psql -l rathern than
checking postmaster.pid. It's not enough to check the existence
of postmaster.pid since DB recovery might be running.

6217a8c7ba Fix some bogosities in the code that deals with estimating the fraction
of tuples we are going to retrieve from a sub-SELECT.  Must have been
half asleep when I did this code the first time :-(
2000-03-14 02:23:15 +00:00
a1642089bf Fixed deficiency where an unterminated (no semicolon) command at end of
psql script would be dropped silently.

e631df3c1b Extend numeric_round and numeric_trunc to accept negative scale inputs
(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.
2000-03-13 02:31:13 +00:00
57cf09591b Remove unnecessary limitations on lengths of bpchar and varchar constants.
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.
2000-03-13 01:54:07 +00:00
a84c95634e Performance improvement for lexing long strings: increase flex's
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.
2000-03-13 01:52:06 +00:00
7cb253ed19 Somehow, the variant NATIONAL CHAR [ VARYING ] was missing from the
set of SQL-standard type names that we accept.

1879175b18 Fix performance bug in constant-expression simplifier. After finding
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...

ef3386affe Fix performance problem in fireRIRonSubselect: with nested subqueries,
fireRIRonSubselect was invoked twice at each subselect, leading to an
exponential amount of wasted effort.
2000-03-12 18:57:05 +00:00
117fa25ae1 Clean up grammar's handling of NULL in expressions: a_expr_or_null is
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.
2000-03-12 00:39:52 +00:00
e8be8ffaf0 Further tweaking of logic that decides when to materialize an uncorrelated
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 ...)

category STRING.  Also, if UNKNOWNOID is passed in, return UNKNOWN_TYPE
not USER_TYPE.
