* Add system indexes to match all caches.Bruce Momjian1999-11-22
| | | | | | | Make all system indexes unique. Make all cache loads use system indexes. Rename *rel to *relid in inheritance tables. Rename cache names to be clearer.
* Change backend-side COPY to write files with permissions 644 not 666Tom Lane1999-11-21
| | | | | | | | | (whoever thought world-writable files were a good default????). Modify the pg_pwd code so that pg_pwd is created with 600 permissions. Modify initdb so that permissions on a pre-existing PGDATA directory are not blindly accepted: if the dir is already there, it does chmod go-rwx to be sure that the permissions are OK and the dir actually is owned by postgres.

| | | | | | | | | | | | | | | | | additional argument specifying the kind of lock to acquire/release (or 'NoLock' to do no lock processing). Ensure that all relations are locked with some appropriate lock level before being examined --- this ensures that relevant shared-inval messages have been processed and should prevent problems caused by concurrent VACUUM. Fix several bugs having to do with mismatched increment/decrement of relation ref count and mismatched heap_open/close (which amounts to the same thing). A bogus ref count on a relation doesn't matter much *unless* a SI Inval message happens to arrive at the wrong time, which is probably why we got away with this sloppiness for so long. Repair missing grab of AccessExclusiveLock in DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi. Recommend 'make clean all' after pulling this update; I modified the Relation struct layout slightly. Will post further discussion to pghackers list shortly.

This is now unnecessary because fd.c takes care of cleaning up open files at transaction abort; worse, after fd.c closed the file copy.c would try to do so *again* at the start of the next COPY command. This would result in havoc in most implementations of stdio library.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | been applied. The patches are in the .tar.gz attachment at the end: varchar-array.patch this patch adds support for arrays of bpchar() and varchar(), which where always missing from postgres. These datatypes can be used to replace the _char4, _char8, etc., which were dropped some time ago. block-size.patch this patch fixes many errors in the parser and other program which happen with very large query statements (> 8K) when using a page size larger than 8192. This patch is needed if you want to submit queries larger than 8K. Postgres supports tuples up to 32K but you can't insert them because you can't submit queries larger than 8K. My patch fixes this problem. The patch also replaces all the occurrences of `8192' and `1<<13' in the sources with the proper constants defined in include files. You should now never find 8192 hardwired in C code, just to make code clearer. -- Massimo Dal Zotto
* Revise backend libpq interfaces so that messages to the frontendTom Lane1999-04-25

|
* From: Magnus Hagander <mha@sollentuna.net>Marc G. Fournier1999-01-11
| | | | | | | | | | | | Here is a first patch to cleanup the backend side of libpq. This patch removes all external dependencies on the "Pfin" and "Pfout" that are declared in pqcomm.h. These variables are also changed to "static" to make sure. Almost all the change is in the handler of the "copy" command - most other areas of the backend already used the correct functions. This change will make the way for cleanup of the internal stuff there - now that all the functions accessing the file descriptors are confined to a single directory.

| | | | | | | | | | | | | | | | | | | | | | if MULTIBYTE is not enabled. So be sure to run initdb. o these patches are made against the latest source tree (after Bruce's massive patch, I think) BTW, I noticed that after running regression, the oid field of pg_type seems disappeared. regression=> select oid from pg_type; ERROR: attribute 'oid' not found this happens after the constraints test. This occures with/without my patches. strange... o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer used, and shoud be removed. o GetDatabaseInfo() in utils/misc/database.c removed (actually in #ifdef 0). seems nobody uses. t-ishii@sra.co.jp

* Use Snapshot in heap access methods.Vadim B. Mikheev1998-07-27
|
* From: t-ishii@sra.co.jpMarc G. Fournier1998-07-26
| | | | | | | | | 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).
* I really hope that I haven't missed anything in this one...Marc G. Fournier1998-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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
* pgindent run before 6.3 release, with Thomas' requested changes.Bruce Momjian1998-02-26

* From: Jan Wieck <jwieck@debis.com>Marc G. Fournier1998-02-25
| | | | | | | | | | 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.
