* Hi all,Bruce Momjian1998-08-28
| | | | | | | | | | | | | | | | | | | | | | | I don't know if this is really related to the initdb problem discussion (haven't followed it enough). But seems so because it fixes a damn problem during index tuple insertion on CREATE TABLE into pg_attribute_relid_attnum_index. Anyway - this bug was really hard to find. During startup the relcache reads in some prepared information about index strategies from a file and then reinitializes the function pointers inside the scanKey data. But for sake it assumed single attribute index tuples (hasn't that changed recently). Thus not all the strategies scanKey entries where initialized properly, resulting in invalid addresses for the btree comparision functions. With the patch at the end the regression tests passed excellent except for the sanity_check that crashed at vacuum and the misc test where the select unique1 from onek2 outputs the two rows in different order.

| | | | | | | | | | lock.patch I have rewritten lock.c cleaning up the code and adding better assert checking I have also added some fields to the lock and xid tags for better support of user locks. There is also a new function which returns an array of pids owning a lock. I'm using this code from over six months and it works fine.

| | | | | | | | assert.patch adds a switch to turn on/off the assert checking if enabled at compile time. You can now compile postgres with assert checking and disable it at runtime in a production environment.
* Can someone please apply this portability patch to genbki.sh ?Bruce Momjian1998-08-25
| | | | | | | | | | | | (Mark or Bruce?) It fixes a problem when cpp gives a warning when precompiling /dev/null like: "/dev/null", line 1: 1506-229 (W) File is empty. This leads to a hangup when doing the description load during initdb, since stderr also ends up in the global1.description and local1_template1.description stderr has to be redirected to /dev/null: Andreas Zeugswetter
* Support SERIAL column type. Expand column marked is_sequence into threeThomas G. Lockhart1998-08-25
| | | | | | | | | | statements: - the table definition with a default clause referencing the sequence; - a CREATE SEQUENCE statement; - a UNIQUE constraint, which expands into a CREATE INDEX statement. This is not a perfect solution, since the sequence will remain even if the table is dropped. Also, there is no absolute protection on updating the sequence column.

| | | | | | | | | | | | | | | | | [AC_MSG_RESULT(yes) AC_DEFINE(HAVE_LONG_INT_64)], this line produces something like: echo "$ac_t""yes" 1>&6 cat >> confdefs.h <<\EOF and would append garbage "yes cat" to confdefs.h. Of course the result confdefs.h is not syntactically correct therefore following tests using confdefs.h would all fail. To avoid the problem, we could switch the order of AC_MSG_RESULT and AC_DEFINE (see attached patch). This happend on my LinuxPPC box. Tatsuo Ishii t-ishii@sra.co.jp

* This is the final state of the rule system for 6.4 after theBruce Momjian1998-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patch is applied: Rewrite rules on relation level work fine now. Event qualifications on insert/update/delete rules work fine now. I added the new keyword OLD to reference the CURRENT tuple. CURRENT will be removed in 6.5. Update rules can reference NEW and OLD in the rule qualification and the actions. Insert/update/delete rules on views can be established to let them behave like real tables. For insert/update/delete rules multiple actions are supported now. The actions can also be surrounded by parantheses to make psql happy. Multiple actions are required if update to a view requires updates to multiple tables. Regular users are permitted to create/drop rules on tables they have RULE permissions for (DefineQueryRewrite() is now able to get around the access restrictions on pg_rewrite). This enables view creation for regular users too. This required an extra boolean parameter to pg_parse_and_plan() that tells to set skipAcl on all rangetable entries of the resulting queries. There is a new function pg_exec_query_acl_override() that could be used by backend utilities to use this facility. All rule actions (not only views) inherit the permissions of the event relations owner. Sample: User A creates tables T1 and T2, creates rules that log INSERT/UPDATE/DELETE on T1 in T2 (like in the regression tests for rules I created) and grants ALL but RULE on T1 to user B. User B can now fully access T1 and the logging happens in T2. But user B cannot access T2 at all, only the rule actions can. And due to missing RULE permissions on T1, user B cannot disable logging. Rules on the attribute level are disabled (they don't work properly and since regular users are now permitted to create rules I decided to disable them). Rules on select must have exactly one action that is a select (so select rules must be a view definition). UPDATE NEW/OLD rules are disabled (still broken, but triggers can do it). There are two new system views (pg_rule and pg_view) that show the definition of the rules or views so the db admin can see what the users do. They use two new functions pg_get_ruledef() and pg_get_viewdef() that are builtins. The functions pg_get_ruledef() and pg_get_viewdef() could be used to implement rule and view support in pg_dump. PostgreSQL is now the only database system I know, that has rewrite rules on the query level. All others (where I found a rule statement at all) use stored database procedures or the like (triggers as we call them) for active rules (as some call them). Future of the rule system: The now disabled parts of the rule system (attribute level, multiple actions on select and update new stuff) require a complete new rewrite handler from scratch. The old one is too badly wired up. After 6.4 I'll start to work on a new rewrite handler, that fully supports the attribute level rules, multiple actions on select and update new. This will be available for 6.5 so we get full rewrite rule capabilities. Jan
* o note that now pg_database has a new attribuite "encoding" evenBruce Momjian1998-08-24
| | | | | | | | | | | | | | | | | | | | | | 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
* Attached is a patch that uses autoconf to determine whether thereBruce Momjian1998-08-23
| | | | | | | | | | | | | | | is a working 64-bit-int type available. In playing around with it on my machine, I found that gcc provides perfectly fine support for "long long" arithmetic ... but sprintf() and sscanf(), which are system-supplied, don't work :-(. So the autoconf test program does a cursory test on them too. If we find that a lot of systems are like this, it might be worth the trouble to implement binary<->ASCII conversion of int64 ourselves rather than relying on sprintf/sscanf to handle the data type. regards, tom lane
