see if we shouldn't block whenever we insert ourselves anywhere before the end of the queue, not only at the front.

rewrite of deadlock checking. Lock holder objects are now reachable from the associated LOCK as well as from the owning PROC. This makes it practical to find all the processes holding a lock, as well as all those waiting on the lock. Also, clean up some of the grottier aspects of the SHMQueue API, and cause the waitProcs list to be stored in the intuitive direction instead of the nonintuitive one. (Bet you didn't know that the code followed the 'prev' link to get to the next waiting process, instead of the 'next' link. It doesn't do that anymore.)

are treated more like 'cancel' interrupts: the signal handler sets a flag that is examined at well-defined spots, rather than trying to cope with an interrupt that might happen anywhere. See pghackers discussion of 1/12/01.

are now critical sections, so as to ensure die() won't interrupt us while we are munging shared-memory data structures. Avoid insecure intermediate states in some code that proc_exit will call, like palloc/pfree. Rename START/END_CRIT_CODE to START/END_CRIT_SECTION, since that seems to be what people tend to call them anyway, and make them be called with () like a function call, in hopes of not confusing pg_indent. I doubt that this is sufficient to make SIGTERM safe anywhere; there's just too much code that could get invoked during proc_exit().

level" locks. A session lock is not released at transaction commit (but it is released on transaction abort, to ensure recovery after an elog(ERROR)). In VACUUM, use a session lock to protect the master table while vacuuming a TOAST table, so that the TOAST table can be done in an independent transaction. I also took this opportunity to do some cleanup and renaming in the lock code. The previously noted bug in ProcLockWakeup, that it couldn't wake up any waiters beyond the first non-wakeable waiter, is now fixed. Also found a previously unknown bug of the same kind (failure to scan all members of a lock queue in some cases) in DeadLockCheck. This might have led to failure to detect a deadlock condition, resulting in indefinite waits, but it's difficult to characterize the conditions required to trigger a failure.

might change it. Experimentation shows that the signal handler call mechanism does not save/restore errno for you, at least not on Linux or HPUX, so this is definitely a real risk.

to ensure that we have released buffer refcounts and so forth, rather than putting ad-hoc operations before (some of the calls to) proc_exit. Add commentary to discourage future hackers from repeating that mistake.

IPC key assignment will now work correctly even when multiple postmasters are using same logical port number (which is possible given -k switch). There is only one shared-mem segment per postmaster now, not 3. Rip out broken code for non-TAS case in bufmgr and xlog, substitute a complete S_LOCK emulation using semaphores in spin.c. TAS and non-TAS logic is now exactly the same. When deadlock is detected, "Deadlock detected" is now the elog(ERROR) message, rather than a NOTICE that comes out before an unhelpful ERROR.

after that dynamic loading isn't working and shared memory handling is broken. Attached with this message, there is a Zip file which contain : * beos.diff = patch file generated with difforig * beos = folder with beos support files which need to be moved in / src/backend/port * expected = foler with three file for message and precision difference in regression test * regression.diff = rule problem (need to kill the backend manualy) * dynloader = dynloader files (they are also in the pacth files, but there is so much modification that I have join full files) Everything works except a problem in 'rules' Is there some problems with rules in the current tree ? It used to works with last week tree. Cyril VELTER

working on the VERY latest version of BeOS. I'm sure there will be alot of comments, but then if there weren't I'd be disappointed! Thanks for your continuing efforts to get this into your tree. Haven't bothered with the new files as they haven't changed. BTW Peter, the compiler is "broken" about the bool define and so on. I'm filing a bug report to try and get it addressed. Hopefully then we can tidy up the code a bit. I await the replies with interest :) David Reid

for details). It doesn't really do that much yet, since there are no short-term memory contexts in the executor, but the infrastructure is in place and long-term contexts are handled reasonably. A few long- standing bugs have been fixed, such as 'VACUUM; anything' in a single query string crashing. Also, out-of-memory is now considered a recoverable ERROR, not FATAL. Eliminate a large amount of crufty, now-dead code in and around memory management. Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and backend startup.

That means you can now set your options in either or all of $PGDATA/configuration, some postmaster option (--enable-fsync=off), or set a SET command. The list of options is in backend/utils/misc/guc.c, documentation will be written post haste. pg_options is gone, so is that pq_geqo config file. Also removed were backend -K, -Q, and -T options (no longer applicable, although -d0 does the same as -Q). Added to configure an --enable-syslog option. changed all callers from TPRINTF to elog(DEBUG)

* Buffer refcount cleanup (per my "progress report" to pghackers, 9/22). * Add links to backend PROC structs to sinval's array of per-backend info, and use these links for routines that need to check the state of all backends (rather than the slow, complicated search of the ShmemIndex hashtable that was used before). Add databaseOID to PROC structs. * Use this to implement an interlock that prevents DESTROY DATABASE of a database containing running backends. (It's a little tricky to prevent a concurrently-starting backend from getting in there, since the new backend is not able to lock anything at the time it tries to look up its database in pg_database. My solution is to recheck that the DB is OK at the end of InitPostgres. It may not be a 100% solution, but it's a lot better than no interlock at all...) * In ALTER TABLE RENAME, flush buffers for the relation before doing the rename of the physical files, to ensure we don't get failures later from mdblindwrt(). * Update TRUNCATE patch so that it actually compiles against current sources :-(. You should do "make clean all" after pulling these changes.
