* Remove remnants of ImmediateInterruptOK handling.Andres Freund2015-02-03
| | | | | | | Now that nothing sets ImmediateInterruptOK to true anymore, we can remove all the supporting code. Reviewed-By: Heikki Linnakangas

| | | | Backpatch certain files through 9.0
* pgindent run for 9.4Bruce Momjian2014-05-06
| | | | | This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.
* Teach on_exit_reset() to discard pending cleanups for dsm.Robert Haas2014-03-10
| | | | | | | | | If a postmaster child invokes fork() and then calls on_exit_reset, that should be sufficient to let it exit() without breaking anything, but dynamic shared memory broke that by not updating on_exit_reset() to discard callbacks registered with dynamic shared memory segments. Per investigation of a complaint from Tom Lane.
* Update copyright for 2014Bruce Momjian2014-01-07
| | | | | Update all files in head, and files COPYRIGHT and legal.sgml in all back branches.
* Allow on-detach callbacks for dynamic shared memory segments.Robert Haas2013-12-18
| | | | | | | | | | | | | | | | | | | | | Just as backends must clean up their shared memory state (releasing lwlocks, buffer pins, etc.) before exiting, they must also perform any similar cleanups related to dynamic shared memory segments they have mapped before unmapping those segments. So add a mechanism to ensure that. Existing on_shmem_exit hooks include both "user level" cleanup such as transaction abort and removal of leftover temporary relations and also "low level" cleanup that forcibly released leftover shared memory resources. On-detach callbacks should run after the first group but before the second group, so create a new before_shmem_exit function for registering the early callbacks and keep on_shmem_exit for the regular callbacks. (An earlier draft of this patch added an additional argument to on_shmem_exit, but that had a much larger footprint and probably a substantially higher risk of breaking third party code for no real gain.) Patch by me, reviewed by KaiGai Kohei and Andres Freund.

* Remove support for on_exit()Peter Eisentraut2011-12-27
| | | | | | All supported platforms support the C89 standard function atexit() (SunOS 4 probably being the last one not to), and supporting both makes the code clumsy.

* Use symbolic names not octal constants for file permission flags.Tom Lane2010-12-10
| | | | | | | | Purely cosmetic patch to make our coding standards more consistent --- we were doing symbolic some places and octal other places. This patch fixes all C-coded uses of mkdir, chmod, and umask. There might be some other calls I missed. Inconsistency noted while researching tablespace directory permissions issue.

* Clear error_context_stack and debug_query_string at the beginning of proc_exit,Tom Lane2010-03-20
| | | | | | | | | | | | | so that we won't try to attach any context printouts to messages that get emitted while exiting. Per report from Dennis Koegel, the context functions won't necessarily work after we've started shutting down the backend, and it seems possible that debug_query_string could be pointing at freed storage as well. The context information doesn't seem particularly relevant to such messages anyway, so there's little lost by suppressing it. Back-patch to all supported branches. I can only demonstrate a crash with log_disconnections messages back to 8.1, but the risk seems real in 8.0 and before anyway.

* Fix all the server-side SIGQUIT handlers (grumble ... why so many identicalTom Lane2009-05-15
| | | | | | | copies?) to ensure they really don't run proc_exit/shmem_exit callbacks, as was intended. I broke this behavior recently by installing atexit callbacks without thinking about the one case where we truly don't want to run those callback functions. Noted in an example from Dave Page.
* Install an atexit(2) callback that ensures that proc_exit's cleanup processingTom Lane2009-05-05
| | | | | | | | | | will still be performed if something in a backend process calls exit() directly, instead of going through proc_exit() as we prefer. This is a second response to the issue that we might load third-party code that doesn't know it should not call exit(). Such a call will now cause a reasonably graceful backend shutdown, if possible. (Of course, if the reason for the exit() call is out-of-memory or some such, we might not be able to recover, but at least we will try.)

* Repair two places where SIGTERM exit could leave shared memory stateTom Lane2008-04-16
| | | | | | | | | | | | | | corrupted. (Neither is very important if SIGTERM is used to shut down the whole database cluster together, but there's a problem if someone tries to SIGTERM individual backends.) To do this, introduce new infrastructure macros PG_ENSURE_ERROR_CLEANUP/PG_END_ENSURE_ERROR_CLEANUP that take care of transiently pushing an on_shmem_exit cleanup hook. Also use this method for createdb cleanup --- that wasn't a shared-memory-corruption problem, but SIGTERM abort of createdb could leave orphaned files lying around. Backpatch as far as 8.2. The shmem corruption cases don't exist in 8.1, and the createdb usage doesn't seem important enough to risk backpatching further.

* Prevent continuing disk-space bloat when profiling (with PROFILE_PID_DIRTom Lane2007-11-04
| | | | | | | | | | enabled) and autovacuum is on. Since there will be a steady stream of autovac worker processes exiting and dropping gmon.out files, allowing them to make separate subdirectories results in serious bloat; and it seems unlikely that anyone will care about those profiles anyway. Limit the damage by forcing all autovac workers to dump in one subdirectory, PGDATA/gprof/avworker/. Per report from Jšrg Beyer and subsequent discussion.

* Patch against 7.2.1 sources. Uses Solaris Intimate Shared MemoryBruce Momjian2002-04-13
| | | | | | | | | | | | | | | for Solaris on SPARC. Scott Brunza (sbrunza@sonalysts.com) gets credit for identifying the issue, making the change, and doing the regression tests. Earlier testing on 7.2rc2 and 7.2 showed performance gains of 1% to 10% on pgbench, osdb-pg, and some locally developed apps. Solaris Intimate Shared Memory is described in "SOLARIS INTERNALS Core Kernel Components" by Jim Mauro and Richard McDougall, Copyright 2001 Sun Microsystem, Inc. ISBN 0-13-022496-0 P.J.

* Change made to elog:Bruce Momjian2002-03-06
| | | | | | | | | | | | | | | | | | | o Change all current CVS messages of NOTICE to WARNING. We were going to do this just before 7.3 beta but it has to be done now, as you will see below. o Change current INFO messages that should be controlled by client_min_messages to NOTICE. o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc. to always go to the client. o Remove INFO from the client_min_messages options and add NOTICE. Seems we do need three non-ERROR elog levels to handle the various behaviors we need for these messages. Regression passed.
