* Change internal string representation of BitString node to include aPeter Eisentraut2000-10-31
| | | | | leading 'b', as it appears to be more convenient this way for the input and node functions.
* Change the parser to convert SQL "position" and "substring" syntax toPeter Eisentraut2000-10-31
| | | | | | | | | | position() and substring() functions, so that it works transparently for bit types as well. Alias the text functions appropriately. Add position() for bit types. Add new constant node T_BitString that represents literals of the form B'1001 and pass those to zpbit type.

* USE_POSIX_TIME replaced by HAVE_TM_ZONE || HAVE_INT_TIMEZONE, which arePeter Eisentraut2000-10-29
| | | | | | | | equivalent. In linux.h there were some #undef HAVE_INT_TIMEZONE, which are useless because HAVE_TM_ZONE overrides it anyway, and messing with configure results isn't cool.

* Okay, here's my attempt at fixing the problems with parentheses inBruce Momjian2000-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subqueries. It passes the normal 'runcheck' tests, and I've tried a few simple things like select 1 as foo union (((((select 2))))) order by foo; There are a few things that it doesn't do that have been talked about here at least a little: 1) It doesn't allow things like "IN(((select 1)))" -- the select here has to be at the top level. This is not new. 2) It does NOT preserve the odd syntax I found when I started looking at this, where a SELECT statement could begin with parentheses. Thus, (SELECT a from foo) order by a; fails. I have preserved the ability, used in the regression tests, to have a single select statement in what appears to be a RuleActionMulti (but wasn't -- the parens were part of select_clause syntax). In my version, this is a special form. This may cause some discussion: I have differentiated the two kinds of RuleActionMulti. Perhaps nobody knew there were two kinds, because I don't think the second form appears in the regression tests. This one uses square brackets instead of parentheses, but originally was otherwise the same as the one in parentheses. In this version of gram.y, the square bracket form treats SELECT statements the same as the other allowed statements. As discussed before on this list, psql cannot make sense out of the results of such a thing, but an application might. And I have designs on just such an application. ++ kevin o'gorman
* Add --version and --help options to "postgres".Peter Eisentraut2000-10-28

* Remove gcc-only macro definitionTatsuo Ishii2000-10-27

* Disallow bits beyond the mask length for CIDR values, per discussionTom Lane2000-10-27
| | | | | | | on pghackers. Arrange for the sort ordering of general INET values to be network part as major sort key, host part as minor sort key. I did not force an initdb for this change, but anyone who's running indexes on general INET values may need to recreate those indexes.
* Re-implement LIMIT/OFFSET as a plan node type, instead of a hack inTom Lane2000-10-26
| | | | | | ExecutorRun. This allows LIMIT to work in a view. Also, LIMIT in a cursor declaration will behave in a reasonable fashion, whereas before it was overridden by the FETCH count.
* Fix breakage I introduced yesterday in MULTIBYTE compilations.Tom Lane2000-10-26
| | | | Sorry 'bout that, chief...
* Clean up gcc warnings in MULTIBYTE mode.Tom Lane2000-10-26

* Clean up broken test for whether to wait for input in SSL case.Tom Lane2000-10-25
| | | | Per discussion with Magnus Hagander.
* Ensure clause_selectivity() behaves sanely when examining an uplevel VarTom Lane2000-10-25
| | | | or a Var that references a subquery output.
* Support SET/SHOW/RESET client_encoding and server_encoding even whenTom Lane2000-10-25
| | | | | | MULTIBYTE support is not compiled (you just can't set them to anything but SQL_ASCII). This should reduce interoperability problems between MB-enabled clients and non-MB-enabled servers.
* Minor cleanup.Tom Lane2000-10-25
|
* Accept CREATE DATABASE WITH ENCODING 'SQL_ASCII' even when MULTIBYTETom Lane2000-10-25
| | | | | | support is not present. This allows a non-MB server to load a pg_dumpall script produced by an MB-enabled server, so long as only ASCII encoding was used.
* Check for SIGHUP and process config file updates just after waitingTom Lane2000-10-24
| | | | for input, not just before.
* Do not execute fastpath function calls if in transaction ABORT state.Tom Lane2000-10-24
| | | | | Just like queries, doing nothing is better than possibly getting weird error messages. Also, improve comments.
* Integer binary operators, from Marko Kreen <marko@l-t.ee>. Renamed bitxorPeter Eisentraut2000-10-24
| | | | operator to '#' for consistency. Parser still needs work.
* Fix AbortOutOfAnyTransaction logic to avoid notice aboutTom Lane2000-10-24
| | | | | | 'AbortTransaction and not in in-progress state' when client disconnects just after an error. Notice seems pretty harmless, so I'm not going to worry about back-patching this into 7.0.* ...
* WAL miscVadim B. Mikheev2000-10-24

* Remove arbitrary limit on number of simultaneously open large objects.Tom Lane2000-10-24
| | | | | This used to make some sense under the old implementation, but now an open LO is pretty darn cheap, so why restrict it?
* Major overhaul of large-object implementation, by Denis Perchine withTom Lane2000-10-24
| | | | | | | | | | | | | kibitzing from Tom Lane. Large objects are now all stored in a single system relation "pg_largeobject" --- no more xinv or xinx files, no more relkind 'l'. This should offer substantial performance improvement for large numbers of LOs, since there won't be directory bloat anymore. It'll also fix problems like running out of locktable space when you access thousands of LOs in one transaction. Also clean up cruft in read/write routines. LOs with "holes" in them (never-written byte ranges) now work just like Unix files with holes do: a hole reads as zeroes but doesn't occupy storage space. INITDB forced!
* If a field is incompressible ('compressed' data is actually larger thanTom Lane2000-10-23
| | | | | | | | source, due to addition of header overhead), store it as plain data rather than pseudo-compressed data. This saves a few microseconds when reading it out, but much more importantly guarantees that the toaster won't actually expand tuples that contain incompressible data. That's essential to avoid 'Tuple too big' failures with large objects.
* Back out xti.h portion of the patch.Bruce Momjian2000-10-23

* New relcache hash table with RelFileNode as key to be usedVadim B. Mikheev2000-10-23
| | | | | | | from bufmgr - it would be nice to have separate hash in smgr for node <--> fd mappings, but for the moment it's easy to add new hash to relcache. Fixed small bug in xlog.c:ReadRecord.
* Some small polishing of Mark Hollomon's cleanup of DROP command: mightTom Lane2000-10-22
| | | | | | | | | as well allow DROP multiple INDEX, RULE, TYPE as well. Add missing CommandCounterIncrement to DROP loop, which could cause trouble otherwise with multiple DROP of items affecting same catalog entries. Try to bring a little consistency to various error messages using 'does not exist', 'nonexistent', etc --- I standardized on 'does not exist' since that's what the vast majority of the existing uses seem to be.
* Makeover for Unixware 7.1.1Peter Eisentraut2000-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile: Add more standard targets. Improve shell redirection in GNU make detection. * src/backend/access/transam/rmgr.c: Fix incorrect(?) C. * src/backend/libpq/pqcomm.c (StreamConnection): Work around accept() bug. * src/include/port/unixware.h: ...with help from here. * src/backend/nodes/print.c (plannode_type): Remove some "break"s after "return"s. * src/backend/tcop/dest.c (DestToFunction): ditto. * src/backend/nodes/readfuncs.c: Add proper prototypes. * src/backend/utils/adt/numutils.c (pg_atoi): Cope specially with strtol() setting EINVAL. This saves us from creating an extra set of regression test output for the affected systems. * src/include/storage/s_lock.h (tas): Correct prototype. * src/interfaces/libpq/fe-connect.c (parseServiceInfo): Don't use variable as dimension in array definition. * src/makefiles/Makefile.unixware: Add support for GCC. * src/template/unixware: same here * src/test/regress/expected/abstime-solaris-1947.out: Adjust whitespace. * src/test/regress/expected/horology-solaris-1947.out: Part of this file was evidently missing. * src/test/regress/pg_regress.sh: Fix shell. mkdir -p returns non-zero if the directory exists. * src/test/regress/resultmap: Add entries for Unixware.
* Fix incorrect logic for clearing BufferDirtiedByMe in ReleaseRelationBuffersTom Lane2000-10-22
| | | | | | | | | and DropBuffers. Formerly we cleared the flag for each buffer currently belonging to the target rel or database, but that's completely wrong! Must look at BufferTagLastDirtied to see whether the BufferDirtiedByMe flag is relevant to target rel or not; this is *independent* of the current contents of the buffer. Vadim spotted this problem, but his fix was only partially correct...
* Patch VACUUM problem with moving chain of update tuples when sourceTom Lane2000-10-22
| | | | | and destination of a tuple lie on the same page. (Previously fixed in REL7_0 branch, now apply to current.)
* Add new datlastsysoid to pg_database.Philip Warner2000-10-22
| | | | | This field stores the last allocated OID after the database was created. Used by pg_dump in deciding what is user-defined vs. system-defined.
* BACKED OUT.Bruce Momjian2000-10-22
| | | | | | | | > Regression tests opr_sanity and sanity_check are now failing. Um, Bruce, I've said several times that I didn't think Perchine's large object changes should be applied until someone had actually reviewed them.
* Crash on NULL again in system table check.Bruce Momjian2000-10-22

* Move DLSUFFIX, AROPT, and CFLAGS_SL settings from template toPeter Eisentraut2000-10-21
| | | | | | | | | Makefile.port, since they are of no use to configure and much of the library magic happens in Makefile.port anyway. Use __alpha, not __alpha__, since the former is universally available. Remove -DNOFIXADE from the compile command line and put it in the port include file.
* First a core dump which can be relieved by:Bruce Momjian2000-10-21

* here it is as requested by Bruce.Bruce Momjian2000-10-21
| | | | | | | | | I tested it restoring my database with > 100000 BLOBS, and dumping it out. But unfortunatly I can not restore it back due to problems in pg_dump. -- Sincerely Yours, Denis Perchine
* WALVadim B. Mikheev2000-10-21

* Add support for VPATH builds, that is, building somewhere else than in thePeter Eisentraut2000-10-20
| | | | | | | | | source directory. This involves mostly makefiles using $(srcdir) when they might have used ".". (Regression tests don't work with this, yet.) Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword in most places, to preserve necessary flags even when the user overrode the flags.
* WAL need in overwrite mode - restored in new wayVadim B. Mikheev2000-10-20
| | | | | (without PageManagetSetMode -:)) Safe shuffle mode behaviour retained.
