Tom Lane 64b4a48ddc Simplify overly-clever Make rule, which evidently confuses at least
some versions of gmake (mine didn't do the right thing, anyway).

Peter Eisentraut 6a68f42648 The heralded `Grand Unified Configuration scheme' (GUC)
That means you can now set your options in either or all of $PGDATA/configuration,
some postmaster option (--enable-fsync=off), or set a SET command. The list of
options is in backend/utils/misc/guc.c, documentation will be written post haste.

pg_options is gone, so is that pq_geqo config file. Also removed were backend -K,
-Q, and -T options (no longer applicable, although -d0 does the same as -Q).

Added to configure an --enable-syslog option.

changed all callers from TPRINTF to elog(DEBUG)

Tom Lane 0f1e39643d Third round of fmgr updates: eliminate calls using fmgr() and
fmgr_faddr() in favor of new-style calls.  Lots of cleanup of
sloppy casts to use XXXGetDatum and DatumGetXXX ...

Bruce Momjian a12a23f0d0 Remove unused include files. Do not touch /port or includes used by defines. 2000-05-30 00:49:57 +00:00
Tom Lane 6ed00fee53 Convert array_map to use new fmgr interface. 2000-05-29 21:02:32 +00:00
Tom Lane a030113197 Tweak fmgrtab generation so that the F_XXX macros that give OIDs for
built-in procedures are named after the prosrc field of pg_proc (ie,
the actual C function name), not the proname field.  This did not use
to make a difference back when the two were always the same, but in the
presence of overloaded proname values we'd best try to use the C name
instead.  AFAICT this change affects no existing code, but it is
necessary to be able to get at some built-in functions that no macro
was being generated for before.

Tom Lane 22a517a40c Repair problems with overrun of timezone name length. Increase MAXTZLEN
to 10, and be consistent about whether it counts the trailing null (it
does not).  Also increase MAXDATELEN to be sure no buffer overflows are
caused by the longer MAXTZLEN.

Tom Lane 091126fa28 Generated header files parse.h and fmgroids.h are now copied into
the src/include tree, so that -I backend is no longer necessary anywhere.
Also, clean up some bit rot in contrib tree.

Tom Lane 18952f6744 Second round of fmgr changes: triggers are now invoked in new style,
CurrentTriggerData is history.

Tom Lane 305d3ce576 Install fmgr rewrite doc as README file.
Need to update user docs still ...
2000-05-28 18:06:55 +00:00
Tom Lane 0a7fb4e918 First round of changes for new fmgr interface. fmgr itself and the
key call sites are changed, but most called functions are still oldstyle.
An exception is that the PL managers are updated (so, for example, NULL
handling now behaves as expected in plperl and plpgsql functions).
NOTE initdb is forced due to added column in pg_proc.

Tom Lane b71761d280 Reduce eqsel()'s fudge-factor for estimating the frequency of values
other than the most common value in a column.  We had had 0.5, make it
0.1 to make it more likely that an indexscan will be chosen.  Really
need better statistics instead, but this should stem the bleeding
meanwhile ...

Tatsuo Ishii 23b0387a94 Fix too long syslog message problem 2000-05-26 12:17:48 +00:00
Bruce Momjian 0460f0502b I am attempting to integrate postgres (v 7.0) with an open source
project I am working on (Recall - a distributed, fault-tolerant,
replicated, storage framework @ http://www.fault-tolerant.org).
Recall is written in C++.  I need to include the postgres headers and
there are some problems when including the headers w/C++.

Attached is a patch generated from postgres/src that fixes my problems.
I was hoping to get this into the main source.  It's very small (2k) and
3 files are changed: backend/utils/fmgr/fmgr.c,
backend/utils/Gen_fmgrtab.sh.in, and include/access/tupdesc.h.

In C++, you get a multiply defined symbol because the variable
(FmgrInfo *fmgr_pl_finfo) is defined in the header (the patch moves it
to the .c file).  The other problem in tupdesc.h is the use of typeid
is a problem in c++ (I renamed it to oidtypeid).

Thanks,
Neal Norwitz

Tom Lane 9dab9ab5e4 Repair memory leaks that caused CacheCxt to grow without bound. We
really ought to fix relcache entry construction so that it does not
do so much with CurrentMemoryContext = CacheCxt.  As is, relatively
harmless leaks in either sequential or index scanning translate to
permanent leaks if they occur when called from relcache build.
For the moment, however, the path of least resistance is to repair
all such leaks...
2000-05-21 02:28:55 +00:00
Tom Lane aa16179118 Add debug code to aid in memory-leak tracking: if SHOW_MEMORY_STATS is
defined then statistics about memory usage of all the global memory
contexts are printed after each commit.
2000-05-21 02:23:30 +00:00
Tom Lane 25a7a7f446 Clean up grotty references to CacheCxt (externs inside functions,
duplicate global declarations, no points for style at all!)

Bruce Momjian a47e20b049 Several compilation and run-time problems occur when building on SGI
IRIX systems using the native compilers.  A summary is:
- Various files use "//" as a comment delimiter in c files.
- Problems caused by assuming "char" is signed.
  cash.in: building -signed the rules regression test fails as described
    in FAQ_QNX4.  If CHAR_MAX is "255U" then ((signed char)CHAR_MAX) is -1.
  postmaster.c: random number regression test failed without this change.
- Some generic build issues and warning message cleanup.

Tom Lane 6dd06737ba Remove configure check for how to abbreviate 'tr A-Z a-z', and instead
just use the portable form,
tr ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
There were a bunch of places that weren't paying attention to configure's
result anyway (including configure itself!?); clean them up too.

Tom Lane e8e7b6305a Tweak selectivity for area-based operators. Still a crock... 2000-05-13 06:04:46 +00:00
Tom Lane 3bd03b3803 Make the indexes on pg_group be shared system relations. 2000-05-05 03:09:43 +00:00
Tatsuo Ishii 832877e95a Modify getdatabaseencoding(), pg_encoding_to_char()
pg_char_to_encoding() in multibyte disbaled case so that it does not
throw an error, rather return HARD CODED default value (currently SQL_ASCII).
This would solve the "non-mb backend vs. mb-enabled frontend" problem.

Tom Lane 87e701b8d5 Clean up const-vs-not-const compiler warning in MULTIBYTE code.
'Twas my fault, I think.
2000-04-20 22:40:18 +00:00
Tom Lane 82849df6c6 Add new selectivity estimation functions for pattern-matching operators
(LIKE and regexp matches).  These are not yet referenced in pg_operator,
so by default the system will continue to use eqsel/neqsel.
Also, tweak convert_to_scalar() logic so that common prefixes of strings
are stripped off, allowing better accuracy when all strings in a table
share a common prefix.

Tom Lane 4ca7d148cb elog(NOTICE) during COPY incorrectly reset lineno to 0, causing any
subsequent elogs() in the same COPY operation to display the wrong
line number.  Fix is to clear lineno only when elog level is such
that we will not return to caller.

Thomas G. Lockhart d221e149b4 Fix (well, add) support for ISO "week" in date_part(). Needed for ODBC.
Fix spelling of "millennium".

Bruce Momjian 52f77df613 Ye-old pgindent run. Same 4-space tabs. 2000-04-12 17:17:23 +00:00
Bruce Momjian a447ae2221 The constant in backend/utils/misc/trace.c, line 32 limits the length of
logged queries to 1024, truncating longer queries.  That is about half of
the size I need (I have a union that is 2K long).  Can someone consider
bumping it to 4K or so?  Patch attached...

Bruce Momjian 28fb1c196b Update create_rule manual page. 2000-04-07 19:17:51 +00:00
Thomas G. Lockhart a349733bbb Add transcendental math functions (sine, cosine, etc)
Add a random number generator and seed setter (random(), SET SEED)
Fix up the interval*float8 math to carry partial months
 into the time field.
Add float8*interval so we have symmetry in the available math.
Fix the parser and define.c to accept SQL92 types as field arguments.
Fix the parser to accept SQL92 types for CREATE TYPE, etc. This is
 necessary to allow...
Bit/varbit support in contrib/bit cleaned up to compile and load
 cleanly. Still needs some work before final release.
Implement the "SOME" keyword as a synonym for "ANY" per SQL92.
Implement ascii(text), ichar(int4), repeat(text,int4) to help
 support the ODBC driver.
Enable the TRUNCATE() function mapping in the ODBC driver.

Tom Lane 14bc951d30 Fix low-probability bug in relcache startup: write_irels wrote the
pg_internal.init file in-place, which meant that if another backend
started at about the same time, it might read the incomplete file.
init_irels tries to guard against that, but I have now seen a crash
due to reading bad data from a partly-written file.  (This may indicate
a kernel bug on my platform?  Not sure.)  Anyway, clearly the safest
course is to write the new pg_internal.init file under a unique temporary
filename, and rename it into place only after it's all written.
2000-03-31 19:39:22 +00:00
Tom Lane e55985d3be Tweak indexscan cost estimation: round estimated # of tuples visited up
to next integer.  Previously, if selectivity was small, we could compute
very tiny scan cost on the basis of estimating that only 0.001 tuple
would be fetched, which is silly.  This naturally led to some rather
silly plans...

Thomas G. Lockhart 1b113a23e5 Change rules for interpreting date/time input to disallow 1 and 3 character
years. Rejects dates like '0.085', which were accepted previously.
2000-03-29 03:57:18 +00:00
Tom Lane eca02fee2c Rename bytea functions to not have upper-case letters in their names.
Clean up grotty coding in them, too.  AFAICS from the CVS logs, these
have been broken since Postgres95, so I'm not going to insist on an
initdb to fix them now...
2000-03-24 02:41:46 +00:00
Tom Lane 5c63975504 Float-to-int conversion functions should return NULL when given NULL
input, not throw a gratuitous elog().
2000-03-23 07:40:00 +00:00
Tom Lane cad764f349 Improve selectivity estimation involving string constants: pay attention
to more than one character, and try to do the right thing in non-ASCII
locales.

Tom Lane f91dd7880f Clean up minor compiler warnings. 2000-03-18 18:57:16 +00:00
Tom Lane 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...
2000-03-17 02:36:41 +00:00
Thomas G. Lockhart 9e7166096e Support full POSIX-style time zone: EST+3, PST-3, etc.
We probably support a superset of the spec, but I don't have the spec
 to confirm this.
Update regression tests to include tests for this format.
2000-03-16 14:38:42 +00:00
Bruce Momjian 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.)

Thomas G. Lockhart 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.
