* Arrange for SET LOCAL's effects to persist until the end of the current topTom Lane2007-09-11
| | | | | | | | | | | | | | transaction, unless rolled back or overridden by a SET clause for the same variable attached to a surrounding function call. Per discussion, these seem the best semantics. Note that this is an INCOMPATIBLE CHANGE: in 8.0 through 8.2, SET LOCAL's effects disappeared at subtransaction commit (leading to behavior that made little sense at the SQL level). I took advantage of the opportunity to rewrite and simplify the GUC variable save/restore logic a little bit. The old idea of a "tentative" value is gone; it was a hangover from before we had a stack. Also, we no longer need a stack entry for every nesting level, but only for those in which a variable's value actually changed.
* Implement function-local GUC parameter settings, as per recent discussion.Tom Lane2007-09-03
| | | | | | | There are still some loose ends: I didn't do anything about the SET FROM CURRENT idea yet, and it's not real clear whether we are happy with the interaction of SET LOCAL with function-local settings. The documentation is a bit spartan, too.
* Restructure autovacuum in two processes: a dummy process, which runsAlvaro Herrera2007-02-15
| | | | | | | | | continuously, and requests vacuum runs of "autovacuum workers" to postmaster. The workers do the actual vacuum work. This allows for future improvements, like allowing multiple autovacuum jobs running in parallel. For now, the code keeps the original behavior of having a single autovac process at any time by sleeping until the previous worker has finished.
* Wording cleanup for error messages. Also change can't -> cannot.Bruce Momjian2007-02-01
| | | | | | | | | | | | | | Standard English uses "may", "can", and "might" in different ways: may - permission, "You may borrow my rake." can - ability, "I can lift that log." might - possibility, "It might rain today." Unfortunately, in conversational English, their use is often mixed, as in, "You may use this variable to do X", when in fact, "can" is a better choice. Similarly, "It may crash" is better stated, "It might crash".

* Add server support for "plugin" libraries that can be used for add-on tasksTom Lane2006-08-15
| | | | | | | | | | | | | | | | | | such as debugging and performance measurement. This consists of two features: a table of "rendezvous variables" that allows separately-loaded shared libraries to communicate, and a new GUC setting "local_preload_libraries" that allows libraries to be loaded into specific sessions without explicit cooperation from the client application. To make local_preload_libraries as flexible as possible, we do not restrict its use to superusers; instead, it is restricted to load only libraries stored in $libdir/plugins/. The existing LOAD command has also been modified to allow non-superusers to LOAD libraries stored in this directory. This patch also renames the existing GUC variable preload_libraries to shared_preload_libraries (after a suggestion by Simon Riggs) and does some code refactoring in dfmgr.c to improve clarity. Korry Douglas, with a little help from Tom Lane.
* Add a feature for automatic initialization and finalization of dynamicallyTom Lane2006-08-08
| | | | | | | | | loaded libraries: call functions _PG_init() and _PG_fini() if the library defines such symbols. Hence we no longer need to specify an initialization function in preload_libraries: we can assume that the library used the _PG_init() convention, instead. This removes one source of pilot error in use of preloaded libraries. Original patch by Ralf Engelschall, preload_libraries changes by me.

* Arrange for the postmaster (and standalone backends, initdb, etc) toTom Lane2005-07-04
| | | | | | | | chdir into PGDATA and subsequently use relative paths instead of absolute paths to access all files under PGDATA. This seems to give a small performance improvement, and it should make the system more robust against naive DBAs doing things like moving a database directory that has a live postmaster in it. Per recent discussion.
* Fix up problems in write_auth_file and parsing of the auth file.Tom Lane2005-06-28
| | | | | In particular, make hba.c cope with zero-length tokens, which it never did properly before. Also, enforce rolcanlogin.
* Replace pg_shadow and pg_group by new role-capable catalogs pg_authidTom Lane2005-06-28
| | | | | | | | and pg_auth_members. There are still many loose ends to finish in this patch (no documentation, no regression tests, no pg_dump support for instance). But I'm going to commit it now anyway so that Alvaro can make some progress on shared dependencies. The catalog changes should be pretty much done.

* Ipcrm -> ipcclean in error message:Bruce Momjian2005-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | --------------------------------------------------------------------------- While playing around, I got the following error message: -- FATAL: pre-existing shared memory block (key 5432001, ID 90898435) is still in use HINT: If you're sure there are no old server processes still running, remove the shared memory block with the command "ipcrm", or just delete the file "/home/hlinnaka/pgsql/data/postmaster.pid". --- Thats normal because I used "kill -9 postmaster" to shut down. The hint advises me to use "ipcrm", but there's the "ipcclean" script in bin for just this purpose. The hint should probably advise to use ipcclean. The attached patch replaces all occurances of "ipcrm" with "ipcclean" in src/backend/utils/init/miscinit.c and all the translations in src/backend/po. While reviewing the patch, I noticed a likely typo in hr.po. While I don't speak Croatian, the translation seems to advise to use the "icpm(1)" command. I changed that to "ipcclean" too.

* Completion of project to use fixed OIDs for all system catalogs andTom Lane2005-04-14

* Treat EPERM as a non-error case when checking to see if old postmasterTom Lane2005-03-18
| | | | | | | | | is still alive. This improves our odds of not getting fooled by an unrelated process when checking a stale lock file. Other checks already in place, plus one newly added in checkDataDir(), ensure that we cannot attempt to usurp the place of a postmaster belonging to a different userid, so there is no need to error out. Add comments indicating the importance of these other checks.

* Adjust configuration-files GUC behavior as per my recent proposal.Tom Lane2004-10-09
| | | | | | | | The vars are renamed to data_directory, config_file, hba_file, and ident_file, and are guaranteed to be set to accurate absolute paths during postmaster startup. This commit does not yet do anything about hiding path values from non-superusers.
* Suppress getppid test on WIN32, per Dave Page.Tom Lane2004-10-04

* Adjust postmaster to recognize that a lockfile containing its parent's PIDTom Lane2004-10-01
| | | | | | | | must be stale. Tweak example startup scripts to not use pg_ctl but launch the postmaster directly, thereby ensuring that only the postmaster's direct parent shell will be a postgres-owned process. In combination these should fix the longstanding problem of the postmaster sometimes refusing to start during reboot because it thinks the old lockfile is not stale.

| | | | | | | | | | | | number of active subtransaction XIDs in each backend's PGPROC entry, and use this to avoid expensive probes into pg_subtrans during TransactionIdIsInProgress. Extend EOXactCallback API to allow add-on modules to get control at subxact start/end. (This is deliberately not compatible with the former API, since any uses of that API probably need manual review anyway.) Add basic reference documentation for SAVEPOINT and related commands. Minor other cleanups to check off some of the open issues for subtransactions. Alvaro Herrera and Tom Lane.

* Tablespaces. Alternate database locations are dead, long live tablespaces.Tom Lane2004-06-18
| | | | | | | | | There are various things left to do: contrib dbsize and oid2name modules need work, and so does the documentation. Also someone should think about COMMENT ON TABLESPACE and maybe RENAME TABLESPACE. Also initlocation is dead, it just doesn't know it yet. Gavin Sherry and Tom Lane.
* Use the new List API function names throughout the backend, and disable theNeil Conway2004-05-30
| | | | | list compatibility API by default. While doing this, I decided to keep the llast() macro around and introduce llast_int() and llast_oid() variants.
* Reimplement the linked list data structure used throughout the backend.Neil Conway2004-05-26
| | | | | | | | | | | | | | | | In the past, we used a 'Lispy' linked list implementation: a "list" was merely a pointer to the head node of the list. The problem with that design is that it makes lappend() and length() linear time. This patch fixes that problem (and others) by maintaining a count of the list length and a pointer to the tail node along with each head node pointer. A "list" is now a pointer to a structure containing some meta-data about the list; the head and tail pointers in that structure refer to ListCell structures that maintain the actual linked list of nodes. The function names of the list API have also been changed to, I hope, be more logically consistent. By default, the old function names are still available; they will be disabled-by-default once the rest of the tree has been updated to use the new API names.

| | | | | | | | | the relcache, and so the notion of 'blind write' is gone. This should improve efficiency in bgwriter and background checkpoint processes. Internal restructuring in md.c to remove the not-very-useful array of MdfdVec objects --- might as well just use pointers. Also remove the long-dead 'persistent main memory' storage manager (mm.c), since it seems quite unlikely to ever get resurrected.
* Win32 signals cleanup. Patch by Magnus Hagander, with input from ClaudioNeil Conway2004-02-08
| | | | | | | | | | | | | | | | | | | | | | Natoli and Bruce Momjian (and some cosmetic fixes from Neil Conway). Changes: - remove duplicate signal definitions from pqsignal.h - replace pqkill() with kill() and redefine kill() in Win32 - use ereport() in place of fprintf() in some error handling in pqsignal.c - export pg_queue_signal() and make use of it where necessary - add a console control handler for Ctrl-C and similar handling on Win32 - do WaitForSingleObjectEx() in CHECK_FOR_INTERRUPTS() on Win32; query cancelling should now work on Win32 - various other fixes and cleanups
* Here's the latest win32 signals code, this time in the form of a patchBruce Momjian2004-01-27
| | | | | | | | | | | | | | | | | against the latest shapshot. It also includes the replacement of kill() with pqkill() and sigsetmask() with pqsigsetmask(). Passes all tests fine on my linux machine once applied. Still doesn't link completely on Win32 - there are a few things still required. But much closer than before. At Bruce's request, I'm goint to write up a README file about the method of signals delivery chosen and why the others were rejected (basically a summary of the mailinglist discussions). I'll finish that up once/if the patch is accepted. Magnus Hagander
