1998-07-27Use Snapshot in heap access methods.Vadim B. Mikheev
1998-07-26From: t-ishii@sra.co.jpMarc G. Fournier
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).
1998-07-24I really hope that I haven't missed anything in this one...Marc G. Fournier
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.
1998-07-191) Queries using the having clause on base tables should work wellBruce Momjian
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 ??

1998-07-09From: Tom Lane <tgl@sss.pgh.pa.us>Marc G. Fournier
Making PQrequestCancel safe to call in a signal handler turned out to be much easier than I feared. So here are the diffs. Some notes: * I modified the postmaster's packet "iodone" callback interface to allow the callback routine to return a continue-or-drop-connection return code; this was necessary to allow the connection to be closed after receiving a Cancel, rather than proceeding to launch a new backend... Being a neatnik, I also made the iodone proc have a typechecked parameter list. * I deleted all code I could find that had to do with OOB. * I made some edits to ensure that all signals mentioned in the code are referred to symbolically not by numbers ("SIGUSR2" not "2"). I think Bruce may have already done at least some of the same edits; I hope that merging these patches is not too painful.

1998-06-16More mb patches.Bruce Momjian
1998-06-16Hi, here are the patches to enhance existing MB handling. This timeBruce Momjian
I have implemented a framework of encoding translation between the backend and the frontend. Also I have added a new variable setting command: SET CLIENT_ENCODING TO 'encoding'; Other features include: Latin1 support more 8 bit cleaness See doc/README.mb for more details. Note that the pacthes are against May 30 snapshot. Tatsuo Ishii

1998-05-06What I've done:Bruce Momjian
1. Rewritten libpq to allow asynchronous clients. 2. Implemented client side of cancel protocol in library, and patched psql.c to send a cancel request upon SIGINT. The backend doesn't notice it yet :-( 3. Implemented 'Z' protocol message addition and renaming of copy in/out start messages. These are implemented conditionally, ie, the client protocol version is checked; so the code should still work with 1.0 clients. 4. Revised protocol and libpq sgml documents (don't have an SGML compiler, though, so there may be some markup glitches here). What remains to be done: 1. Implement addition of atttypmod field to RowDescriptor messages. The client-side code is there but ifdef'd out. I have no idea what to change on the backend side. The field should be sent only if protocol >= 2.0, of course. 2. Implement backend response to cancel requests received as OOB messages. (This prolly need not be conditional on protocol version; just do it if you get SIGURG.) 3. Update libpq.3. (I'm hoping this can be generated mechanically from libpq.sgml... if not, will do it by hand.) Is there any other doco to fix? 4. Update non-libpq interfaces as necessary. I patched libpgtcl so that it would compile, but haven't tested it. Dunno what needs to be done with the other interfaces. Have at it! Tom Lane

1998-04-27This patch...Bruce Momjian
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. S Darren.

1998-04-07Back out char2-char16 removal. Add later.Bruce Momjian
1998-04-06Hi,Bruce Momjian
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

1998-03-30The buffer overrun while creating sequences turns out to be a readBruce Momjian
access overrun. For the sake of doing things properly here is a patch which fixes it. This patch is for the file backend/commands/sequence.c. Maurice Gittens
1998-03-30There's a patch attached to fix gcc 2.8.x warnings, except for theBruce Momjian
yyerror ones from bison. It also includes a few 'enhancements' to the C programming style (which are, of course, personal). The other patch removes the compilation of backend/lib/qsort.c, as qsort() is a standard function in stdlib.h and can be used any where else (and it is). It was only used in backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c, and backend/storage/page/bufpage.c > > Some or all of these changes might not be appropriate for v6.3, since we > > are in beta testing and since they do not affect the current functionality. > > For those cases, how about submitting patches based on the final v6.3 > > release? There's more to come. Please review these patches. I ran the regression tests and they only failed where this was expected (random, geo, etc). Cheers, Jeroen

1998-02-25From: Jan Wieck <jwieck@debis.com>Marc G. Fournier
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.

1998-02-13From: Jan Wieck <jwieck@debis.com>Marc G. Fournier
Someone changed the parser to build a TypeName node on CREATE FUNCTION in any case. As a side effect, ALL! functions created got the proretset attribute to true. Thus for a SELECT the parser wrapped an Iter node around the Expr and since singleton functions set isDone the Iter returns no tuple up.
