Tom Lane 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.

Tom Lane 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.

Tom Lane 7cb253ed19 Somehow, the variant NATIONAL CHAR [ VARYING ] was missing from the
set of SQL-standard type names that we accept.

Tom Lane 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...

Tom Lane ef3386affe Fix performance problem in fireRIRonSubselect: with nested subqueries,
fireRIRonSubselect was invoked twice at each subselect, leading to an
exponential amount of wasted effort.

Tom Lane 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.

Tom Lane 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 ...)

Tom Lane bbe1ff7404 Make TypeCategory think that NAME is a member of type
category STRING.  Also, if UNKNOWNOID is passed in, return UNKNOWN_TYPE
not USER_TYPE.

Tom Lane c9f287e49b Further fixes for bogus list-slinging, scribbling on input, etc in type
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.

Tom Lane 73f5b0847b exec_simple_check_plan() must not allow a plan having initPlans or
subPlans to be considered 'simple'.  This fixes reported problem with
'return exists (select 1 from foo);' in plpgsql function.

Tom Lane f3a9d75ebd Finish cleaning up backend's handling of /* ... */ and -- comments,
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.

Tom Lane 370186e807 Update libpq documentation for PQconndefaults() change. Add section
about thread-safeness of the library.
2000-03-11 03:09:28 +00:00
Tom Lane a71daab4b4 Change PQconndefaults() to return a malloc'd array, instead of a static
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.

Tom Lane dad5bb01ba Redo permissions-checking code so that it does the right thing at APPEND
nodes.  The former version failed to check permissions of relations that
were referenced in second and later clauses of UNIONs, and it did not
check permissions of tables referenced via inheritance.

Bruce Momjian 791bc6838d Hi,
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!!

Bruce Momjian f43ec05d05 I've made a diff against the 7.0beta1 tree that accomplishes several things:
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!

Bruce Momjian 26c953e373 Bruce and all:
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?

Bruce Momjian 326e2155d9 Hi Peter,
I try change prompt in the psql, but it is set '.' (as '%m') for
non-TCP/IP
connection. This small patch try use uname() information for non-TCP/IP
instead '.'.

Bruce Momjian eae5184d11 Hi,
the to_char() source code is large, here are regression tests for
numeric/timestamp/int8 part. It is probably enough test for formatting
code in the formatting.c module. The others (float4/float8/int4) types
share this formatting code and eventual bugs for these types aren't
few probable.

 Patch fix timestamp_to_char() for infinity/invalid timestamp too.

Bruce Momjian 8fa8f80c1a I've recently written to pgsql-ports about a problem with PG7.0 on NT
(Subj: [PORTS] initdb problem on NT with 7.0).  Since nobody helped me,
I had to find out the reson.  The difference between NT and Linux (for
instance) is that "open( path, O_RDWR );" opens a file in text mode.  So
sometime less block can be read than required.

I suggest a following patch.  BTW the situation appeared before, see
hba.c, pqcomm.c and others.

Bruce Momjian 91124a2f66 Fix problems with pg_upgrade found by Kardos, Dr. Andrea 2000-03-07 23:09:34 +00:00
Bruce Momjian 52d39d519a Sorting for the inet data type randomly returns the wrong result
when you have networks with the same prefix, but different netmasks.

This is due to the fact that occassionally there is random
(uninitialized?)
data in the extra bits past the point where the netmask cares about
them.

ie (real data from a real live database):

  10.0/10 == 00001010.00100000.00100000.00011000
  10.0/11 == 00001010.00000000.00000000.00000000
                        ^ Bad data, normally never seen

The v4bitncmp() function was only taking one bit length argument so
it would determine that the networks were different, even though
they really aren't (and the netmask test wouldn't be used).  This
ONLY happens if the tuple with the longer bit length is used as the
ip_bits() for the v4bitncmp call AND there happens to be junk data
in place in the shorter tuple.  Odd and random, but I saw it happen
a couple times so...
