Hi,

    as  proposed here comes the first patch for the query rewrite
    system.

Vadim B. Mikheev be8300b18f Use Snapshot in heap access methods. 1998-07-27 19:38:40 +00:00
Marc G. Fournier 5979d73841 From: t-ishii@sra.co.jp
As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.

P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).

Marc G. Fournier bf00bbb0c4 I really hope that I haven't missed anything in this one...
From: t-ishii@sra.co.jp

Attached are patches to enhance the multi-byte support.  (patches are
against 7/18 snapshot)

* determine encoding at initdb/createdb rather than compile time

Now initdb/createdb has an option to specify the encoding. Also, I
modified the syntax of CREATE DATABASE to accept encoding option. See
README.mb for more details.

For this purpose I have added new column "encoding" to pg_database.
Also pg_attribute and pg_class are changed to catch up the
modification to pg_database.  Actually I haved added pg_database_mb.h,
pg_attribute_mb.h and pg_class_mb.h. These are used only when MB is
enabled. The reason having separate files is I couldn't find a way to
use ifdef or whatever in those files. I have to admit it looks
ugly. No way.

* support for PGCLIENTENCODING when issuing COPY command

commands/copy.c modified.

* support for SQL92 syntax "SET NAMES"

See gram.y.

* support for LATIN2-5
* add UNICODE regression test case
* new test suite for MB

New directory test/mb added.

* clean up source files

Basic idea is to have MB's own subdirectory for easier maintenance.
These are include/mb and backend/utils/mb.

Bruce Momjian 460b20a43f 1) Queries using the having clause on base tables should work well
now. Here some tested features, (examples included in the patch):

1.1) Subselects in the having clause 1.2) Double nested subselects
1.3) Subselects used in the where clause and in the having clause
     simultaneously 1.4) Union Selects using having 1.5) Indexes
on the base relations are used correctly 1.6) Unallowed Queries
are prevented (e.g. qualifications in the
     having clause that belong to the where clause) 1.7) Insert
into as select

2) Queries using the having clause on view relations also work
   but there are some restrictions:

2.1) Create View as Select ... Having ...; using base tables in
the select 2.1.1) The Query rewrite system:

2.1.2) Why are only simple queries allowed against a view from 2.1)
? 2.2) Select ... from testview1, testview2, ... having...; 3) Bug
in ExecMergeJoin ??

Bruce Momjian 09baa3cc81 This patch...
1. Removes the unnecessary "#define AbcRegProcedure 123"'s from
pg_proc.h.

2. Changes those #defines to use the names already defined in
fmgr.h.

3. Forces the make of fmgr.h in backend/Makefile instead of having
it
   made as a dependency in access/common/Makefile  *hack*hack*hack*

4. Rearranged the #includes to a less helter-skelter arrangement,
also
    changing <file.h> to "file.h" to signify a non-system header.

5. Removed "pg_proc.h" from files where its only purpose was for
the
   #defines removed in item #1.

6. Added "fmgr.h" to each file changed for completeness sake.

Turns out that #6 was not necessary for some files because fmgr.h
was being included in a roundabout way SIX levels deep by the first
include.

"access/genam.h"
 ->"access/relscan.h"
   ->"utils/rel.h"
     ->"access/strat.h"
       ->"access/skey.h"
	 ->"fmgr.h"

So adding fmgr.h really didn't add anything to the compile, hopefully
just made it clearer to the programmer.

Bruce Momjian db21523314 Back out char2-char16 removal. Add later. 1998-04-07 18:14:38 +00:00
Bruce Momjian 1e801a8f16 Hi,
Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.

It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.

This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )

This patch is against the 6.3 sources, as it took a while to
complete.

Please review and apply,

Cheers,

Jeroen van Vianen

Bruce Momjian 57b5966405 The following uuencoded, gzip'd file will ...
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql.  4. Modify
the regression test scripts and outputs to match up.

Might require new regression.{SYSTEM} files...

Bruce Momjian c579ce0fb0 I started adding the Having Clause and it works quite fine for
sequential scans! (I think it will also work with hash, index, etc
but I did not check it out! I made some High level changes which
should work for all access methods, but maybe I'm wrong. Please
let me know.)

Now it is possible to make queries like:

select s.sname, max(p.pid), min(p.pid) from part p, supplier s
where s.sid=p.sid group by s.sname having max(pid)=6 and min(pid)=1
or avg(pid)=4;

Having does not work yet for queries that contain a subselect
statement in the Having clause, I'll try to fix this in the next
days.

If there are some bugs, please let me know, I'll start to read the
mailinglists now!

Now here is the patch against the original 6.3 version (no snapshot!!):

Marc G. Fournier 780068f812 From: Jan Wieck <jwieck@debis.com>
seems  that  my last post didn't make it through. That's good
    since  the  diff  itself  didn't  covered  the  renaming   of
    pg_user.h to pg_shadow.h and it's new content.

    Here  it's  again.  The  complete regression test passwd with
    only some  float  diffs.  createuser  and  destroyuser  work.
    pg_shadow cannot be read by ordinary user.
1998-02-25 13:09:49 +00:00
Marc G. Fournier 7b30490bc9 First step done,
below  is  the patch to have views to override the permission
    checks for the accessed tables. Now we can do the following:

    CREATE VIEW db_user AS SELECT
         usename,
         usesysid,
         usecreatedb,
         usetrace,
         usecatupd,
         '**********'::text as passwd,
         valuntil
        FROM pg_user;

    REVOKE ALL ON pg_user FROM public;
    REVOKE ALL ON db_user FROM public;
    GRANT SELECT ON db_user TO public;

Fix crash when doing:

	select sum(x+1) from test where 1 > 0;

Marc G. Fournier 374bb5d261 Some *very* major changes by darrenk@insightdist.com (Darren King)
==========================================
What follows is a set of diffs that cleans up the usage of BLCKSZ.

As a side effect, the person compiling the code can change the
value of BLCKSZ _at_their_own_risk_.  By that, I mean that I've
tried it here at 4096 and 16384 with no ill-effects.  A value
of 4096 _shouldn't_ affect much as far as the kernel/file system
goes, but making it bigger than 8192 can have severe consequences
if you don't know what you're doing.  16394 worked for me, _BUT_
when I went to 32768 and did an initdb, the SCSI driver broke and
the partition that I was running under went to hell in a hand
basket. Had to reboot and do a good bit of fsck'ing to fix things up.

The patch can be safely applied though.  Just leave BLCKSZ = 8192
and everything is as before.  It basically only cleans up all of the
references to BLCKSZ in the code.

If this patch is applied, a comment in the config.h file though above
the BLCKSZ define with warning about monkeying around with it would
be a good idea.

Darren  darrenk@insightdist.com

(Also cleans up some of the #includes in files referencing BLCKSZ.)

Marc G. Fournier 6e337eef45 Major cleanout of PORTNAME variables from Makefiles...bound to screw up

1997-12-20 00:29:35 +00:00
Marc G. Fournier 5379b84eff More cleanups. I can now compile without PORTNAME being defined n
Makefile.global.

End result, if all goes well, should allow for much easier porting, since
there will no longer be a concept of a "port".  Most, if not everything,
*should* be determined by configure, or by the compiler itself.  Still
work to be done though :)

Marc G. Fournier b7559f94cd This change should have no practical effect but it is the more
correct way to do this.  Theoretically you could have a NULL
pointer that isn't represented internally as all 0 bits.  This
guarantees that it convert correctly.
