| | | | | | | query representation. Note that GEQO_RELS setting is now interpreted as the number of top-level items in the FROM list, not necessarily the number of relations in the query. This seems appropriate since we are only doing join-path searching over the top-level items.
* Implement differentiation between CURRENT_USER and SESSION_USER as per SQL.Peter Eisentraut2000-09-195-45/+85
| | | | | | There is still no effective difference but it will kick in once setuid functions exist (not included here). Make old getpgusername() alias for current_user.

* Parse JOIN/ON conditions with the proper visibility of input columns,Tom Lane2000-09-171-30/+115
| | | | | | | | ie, consider only the columns coming from the JOIN clause's sub-clauses. Also detect attempts to reference columns belonging to other tables (which would still be possible using an explicitly-qualified name). I'm not sure this implements the spec's semantics 100% accurately, but at least it gives plausible behavior.
* Support for DESTDIR make variable. This is used as in `make installPeter Eisentraut2000-09-172-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | DESTDIR=/else/where' and prepends the value of DESTDIR to the full installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows users to install the package into a location different from the one that was configured and hard-coded into various scripts, e.g., for creating binary packages. DESTDIR is in many cases preferrable over `make install prefix=/else/where' because a) `prefix' affects the path that is hard-coded into the files, which can lead to a `make install prefix=xxx' (as done by the regression test driver) corrupting the files in the source tree with wrong paths. b) it doesn't work at all if a directory was overridden to not depend on `prefix', e.g., --sysconfdir=/etc. (Updating the regression test driver to use DESTDIR is a separate undertaking.)

* This patch implements a different "relkind"Bruce Momjian2000-09-1210-32/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for views. Views are now have a "relkind" of RELKIND_VIEW instead of RELKIND_RELATION. Also, views no longer have actual heap storage files. The following changes were made 1. CREATE VIEW sets the new relkind 2. The executor complains if a DELETE or INSERT references a view. 3. DROP RULE complains if an attempt is made to delete a view SELECT rule. 4. CREATE RULE "_RETmytable" AS ON SELECT TO mytable DO INSTEAD ... 1. checks to make sure mytable is empty. 2. sets the relkind to RELKIND_VIEW. 3. deletes the heap storage files. 5. LOCK myview is not allowed. :) 6. the regression test type_sanity was changed to account for the new relkind value. 7. CREATE INDEX ON myview ... is not allowed. 8. VACUUM myview is not allowed. VACUUM automatically skips views when do the entire database. 9. TRUNCATE myview is not allowed. THINGS LEFT TO THINK ABOUT o pg_views o pg_dump o pgsql (\d \dv) o Do we really want to be able to inherit from views? o Is 'DROP TABLE myview' OK? -- Mark Hollomon

| | | | | | | | | | | | | | | | | | | Here's the multibyte aware version of my patch to fix the truncation of the rulename autogenerated during a CREATE VIEW. I've modified all the places in the backend that want to construct the rulename to use the MakeRetrieveViewRuleName(), where I put the #ifdef MULTIBYTE, so that's the only place that knows how to construct a view rulename. Except pg_dump, where I replicated the code, since it's a standalone binary. The only effect the enduser will see is that views with names len(name) > NAMEDATALEN-4 will fail to be created, if the derived rulename clases with an existing rule: i.e. the user is trying to create two views with long names whose first difference is past NAMEDATALEN-4 (but before NAMEDATALEN: that'll error out after the viewname truncation.) In no case will the user get left with a table without a view rule, as the current code does. Ross Reedstrom

* Code cleanup of user name and user id handling in the backend. The currentPeter Eisentraut2000-09-0624-262/+203
| | | | | | | | | | | user is now defined in terms of the user id, the user name is only computed upon request (for display purposes). This is kind of the opposite of the previous state, which would maintain the user name and compute the user id for permission checks. Besides perhaps saving a few cycles (integer vs string), this now creates a single point of attack for changing the user id during a connection, for purposes of "setuid" functions, etc.

* * to_char:Bruce Momjian2000-08-293-59/+151
| | | | | | | | | | | | | | | | | | | | | | | - full support for IW (ISO week) and vice versa conversion for IW too (the to_char 'week' support is now complete and I hope correct). Thomas, I use for IW code from timestamp.c, for this I create separate function date2isoweek() from original 'case DTK_WEEK:' code in the timestamp_part(). I mean will better use one code for same feature in date_part() and in to_char(). The isoweek2date() is added to timestamp.c too. Right? IMHO in 7.1 will all to_char's features complete. It is cca 41 templates for date/time and cca 21 for numbers. * to_ascii: - gcc, is it correct now? :-) In the patch is documentation for to_char's IW and for to_ascii(). Karel
* This is mostly the same as an earlier patch IBruce Momjian2000-08-292-7/+239
| | | | | | | | | | | | | | | | | | | didn't hear anything about, but which would have broken with the function manager changes anyway. Well, this patch checks that a unique constraint of some form (unique or pk) is on the referenced columns of an FK constraint and that the columns in the referencing table exist at creation time. The former is to move closer to SQL compatibility and the latter is in answer to a bug report. I also added a basic check of this functionality to the alter table and foreign key regression tests.

* Make the location of the Kerberos server key file run time configurablePeter Eisentraut2000-08-254-37/+40
| | | | | | | | | (rather than compile time). For libpq, even when Kerberos support is compiled in, the default user name should still fall back to geteuid() if it can't be determined via the Kerberos system. A couple of fixes for string type configuration parameters, now that there is one.
