* More binary I/O routines.Tom Lane2003-05-13
|
* COPY BINARY uses the new binary I/O routines. Update a few more datatypesTom Lane2003-05-09
| | | | so that COPY BINARY regression test passes.
* Add explicit tests for division by zero to all user-accessible integerTom Lane2003-03-11
| | | | | | | | division and modulo functions, to avoid problems on OS X (which fails to trap 0 divide at all) and Windows (which traps it in some bizarre nonstandard fashion). Standardize on 'division by zero' as the one true spelling of this error message. Add regression tests as suggested by Neil Conway.
* Avoid gratuitous variation in spelling of same error message.Tom Lane2003-01-21

* Point does not return a center of lseg.Tom Lane2002-12-30
| | | | Kenji Sugita
* Repair prehistoric logic error in lseg_eq and lseg_ne.Tom Lane2002-11-29
|
* Add new palloc0 call as merge of palloc and MemSet(0).Bruce Momjian2002-11-13
|
* Back out use of palloc0 in place if palloc/MemSet. Seems constant lenBruce Momjian2002-11-11
| | | | to MemSet is a performance boost.
* Merge palloc()/MemSet(0) calls into a single palloc0() call.Bruce Momjian2002-11-10
|
* Replace imprecise value of PI with a better one, and tweak circle_polyTom Lane2002-11-08
| | | | | | in hopes of reducing platform-to-platform variations in its results. This will cause the geometry regression test to start failing on some platforms. I plan to update the test later today.
* Add extra_float_digits GUC parameter to allow adjustment of displayedTom Lane2002-11-08
| | | | | | | precision for float4, float8, and geometric types. Set it in pg_dump so that float data can be dumped/reloaded exactly (at least on platforms where the float I/O support is properly implemented). Initial patch by Pedro Ferreira, some additional work by Tom Lane.
* Be careful to include postgres.h *before* any system headers, to ensureTom Lane2002-09-05
| | | | | | that the right flavors of largefile-related definitions are seen. Most of these changes are probably unnecessary, but better safe than sorry.
* pgindent run.Bruce Momjian2002-09-04

I've attached a patch which should fix these problems. Neil Conway
* Mark 'line' as 'not implemented' in SGML and psql \dT, per ThomasBruce Momjian2002-07-16
| | | | Lockhart. initdb not forced.
* Update copyright to 2002.Bruce Momjian2002-06-20
|
* Remove unnecessary pfree's in geometric operators. At least one of theseTom Lane2002-05-14
| | | | | | | is actively dangerous, per bug report from Ewald Geschwinde 14-May-02, and several of the rest look suspicious to me. Since there is no longer any significant value in retail pfree's in these functions, just get rid of all of them for safety's sake.
* pgindent run on all C files. Java run to follow. initdb/regressionBruce Momjian2001-10-25
| | | | tests pass.
* path_inter, path_distance, path_length, dist_ppath now do the rightTom Lane2001-10-13
| | | | | things with closed paths --- ie, include the closing line segment in their calculations. Per bug report from Curtis Barrett 9-Oct-01.
* pgindent run. Make it all clean.Bruce Momjian2001-03-22
|
* Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.Bruce Momjian2001-01-24
|
* Repair erroneous use of hashvarlena() for MACADDR, which is not aTom Lane2000-12-08
| | | | | | | varlena type. (I did not force initdb, but you won't see the fix unless you do one.) Also, make sure all index support operators and functions are careful not to leak memory for toasted inputs; I had missed some hash and rtree support ops on this point before.
* Ensure that all uses of <ctype.h> functions are applied to unsigned-charTom Lane2000-12-03
| | | | | values, whether the local char type is signed or not. This is necessary for portability. Per discussion on pghackers around 9/16/00.
* Convert all remaining geometric operators to new fmgr style. ThisTom Lane2000-07-30
| | | | | | | | allows fixing problems with operators that expected to be able to return a NULL, such as the '#' line-segment-intersection operator that tried to return NULL when the two segments don't intersect. (See, eg, bug report from 1-Nov-99 on pghackers.) Fix some other bugs in passing, such as backwards comparison in path_distance().
* PATH and POLYGON datatypes are now TOASTable. Associated functionsTom Lane2000-07-29
| | | | | updated to new fmgr style. Deleted hoary old functions for compatibility with pre-6.1 representations of these datatypes.
* Big warnings cleanup for Solaris/GCC. Down to about 40 now, butPeter Eisentraut2000-06-14
| | | | | | | | | | | we'll get there one day. Use `cat' to create aclocal.m4, not `aclocal'. Some people don't have automake installed. Only run the autoconf rule in the top-level GNUmakefile if the invoker specified `make configure', don't run it automatically because of CVS timestamp skew.
* Another batch of fmgr updates. I think I have gotten all old-styleTom Lane2000-06-13
| | | | | functions that take pass-by-value datatypes. Should be ready for port testing ...
* Ye-old pgindent run. Same 4-space tabs.Bruce Momjian2000-04-12
|
* 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.
* Add:Bruce Momjian2000-01-26
| | | | | | * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.
* Fixed all elog related warnings, as well as a few others.Peter Eisentraut2000-01-15

* This patch will avoid SIGFPE on some geo functions , if PostgreSQL is compiledBruce Momjian1999-12-21
| | | | | | | | | | | with DEC C. DEC C doesn't handle double values greater than DBL_MAX, but some PostgreSQL geo functions assign greater than DBL_MAX values to some vars in some special cases - that couses SIGFPE. I dunno if that is the only place to fix to work well with DEC C. Kirill Nosov.
* Move some system includes into c.h, and remove duplicates.Bruce Momjian1999-07-17
|
* Update #include cleanupsBruce Momjian1999-07-16
|
* Clean up #include in /include directory. Add scripts for checking includes.Bruce Momjian1999-07-15
|
* Cleanup of /include #include's, for 6.6 only.Bruce Momjian1999-07-14
|
* From: Tatsuo Ishii <t-ishii@sra.co.jp>Marc G. Fournier1999-02-21
| | | | | | Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef NOT_USED" for current. I have tested these patches in that the postgres binaries are identical.
* Change my-function-name-- to my_function_name, and optimizer renames.Bruce Momjian1999-02-13
|
* Very minor cleanup of no-op code.Thomas G. Lockhart1998-10-29
|
* Get rid of some minor compiler warnings.Tom Lane1998-10-26
|
* OK, folks, here is the pgindent output.Bruce Momjian1998-09-01
|
* Renaming cleanup, no pgindent yet.Bruce Momjian1998-09-01
|
* Disable not-ready-to-use support code for the line data type.Thomas G. Lockhart1998-08-16
| | | | | | Bracket things with #ifdef ENABLE_LINE_TYPE. The line data type has always been used internally to support other types, but I/O routines have never been defined for it.
* Some old cleanup fixes for close_ps() from G. Thaker.Thomas G. Lockhart1998-08-15
|
* Remove un-needed braces around single statements.Bruce Momjian1998-06-15
|
* Make a few line routines visible.Thomas G. Lockhart1998-05-09
| | | | Incorporate patches from Gautam for line/point intersection.
* pgindent run before 6.3 release, with Thomas' requested changes.Bruce Momjian1998-02-26
|
* Define boolean functions for lseg <, <=, <>, >=, >Thomas G. Lockhart1998-02-03
| | | | | | | | | Define close_ls(), close_lseg(), lseg_length(). Write real code for close_sb(), close_pb(), inter_sb(), inter_lb(). Repair lseg_perp() which determines if two lsegs are perpendicular. Repair lseg_dt() distance between two lsegs. Note: close_sl() is clearly broken but will repair later (calculating point on lseg rather than point on line).
* Allow varchar() to only store needed bytes. Remove PALLOC,PALLOCTYPE,PFREE. ↵Bruce Momjian1998-01-07
| | | | Clean up use of VARDATA.
* Change some ABORTS to ERROR. Add line number when COPY Failure.Bruce Momjian1998-01-05
