* Move pqsignal() to libpgport.Tom Lane2013-03-17
| | | | | | | | | We had two copies of this function in the backend and libpq, which was already pretty bogus, but it turns out that we need it in some other programs that don't use libpq (such as pg_test_fsync). So put it where it probably should have been all along. The signal-mask-initialization support in src/backend/libpq/pqsignal.c stays where it is, though, since we only need that in the backend.

* Remove the use of the pg_auth flat file for client authentication.Tom Lane2009-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | (That flat file is now completely useless, but removal will come later.) To do this, postpone client authentication into the startup transaction that's run by InitPostgres. We still collect the startup packet and do SSL initialization (if needed) at the same time we did before. The AuthenticationTimeout is applied separately to startup packet collection and the actual authentication cycle. (This is a bit annoying, since it means a couple extra syscalls; but the signal handling requirements inside and outside a transaction are sufficiently different that it seems best to treat the timeouts as completely independent.) A small security disadvantage is that if the given database name is invalid, this will be reported to the client before any authentication happens. We could work around that by connecting to database "postgres" instead, but consensus seems to be that it's not worth introducing such surprising behavior. Processing of all command-line switches and GUC options received from the client is now postponed until after authentication. This means that PostAuthDelay is much less useful than it used to be --- if you need to investigate problems during InitPostgres you'll have to set PreAuthDelay instead. However, allowing an unauthenticated user to set any GUC options whatever seems a bit too risky, so we'll live with that.

* Separate out bgwriter code into a logically separate module, ratherTom Lane2004-05-29
| | | | | | | | | than being random pieces of other files. Give bgwriter responsibility for all checkpoint activity (other than a post-recovery checkpoint); so this child process absorbs the functionality of the former transient checkpoint and shutdown subprocesses. While at it, create an actual include file for postmaster.c, which for some reason never had its own file before.
* Here's an attempt at new socket and signal code for win32.Bruce Momjian2004-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It works on the principle of turning sockets into non-blocking, and then emulate blocking behaviour on top of that, while allowing signals to run. Signals are now implemented using an event instead of APCs, thus getting rid of the issue of APCs not being compatible with "old style" sockets functions. It also moves the win32 specific code away from pqsignal.h/c into port/win32, and also removes the "thread style workaround" of the APC issue previously in place. In order to make things work, a few things are also changed in pgstat.c: 1) There is now a separate pipe to the collector and the bufferer. This is required because the pipe will otherwise only be signalled in one of the processes when the postmaster goes down. The MS winsock code for select() must have some kind of workaround for this behaviour, but I have found no stable way of doing that. You really are not supposed to use the same socket from more than one process (unless you use WSADuplicateSocket(), in which case the docs specifically say that only one will be flagged). 2) The check for "postmaster death" is moved into a separate select() call after the main loop. The previous behaviour select():ed on the postmaster pipe, while later explicitly saying "we do NOT check for postmaster exit inside the loop". The issue was that the code relies on the same select() call seeing both the postmaster pipe *and* the pgstat pipe go away. This does not always happen, and it appears that useing WSAEventSelect() makes it even more common that it does not. Since it's only called when the process exits, I don't think using a separate select() call will have any significant impact on how the stats collector works. Magnus Hagander
* Here is a patch that implements setitimer() on win32. With this patchBruce Momjian2004-02-18
| | | | | | | | | | | applied, deadlock detection and statement_timeout now works. The file timer.c goes into src/backend/port/win32/. The patch also removes two lines of "printf debugging" accidentally left in pqsignal.h, in the console control handler. Magnus Hagander
* 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
* Pgindent win32 signal code.Bruce Momjian2004-01-27

* 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

| | | | | | | | We will no longer try to send elog messages to the client before we have initialized backend libpq (oops); however, reporting bogus commandline switches via elog does work now (not irrelevant, because of PGOPTIONS).

* Restructure the key include files per recent pghackers discussion: thereTom Lane2001-02-10
| | | | | | | | | | | are now separate files "postgres.h" and "postgres_fe.h", which are meant to be the primary include files for backend .c files and frontend .c files respectively. By default, only include files meant for frontend use are installed into the installation include directory. There is a new make target 'make install-all-headers' that adds the whole content of the src/include tree to the installed fileset, for use by people who want to develop server-side code without keeping the complete source tree on hand. Cleaned up a whole lot of crufty and inconsistent header inclusions.

* First phase of memory management rewrite (see backend/utils/mmgr/READMETom Lane2000-06-28
| | | | | | | | | | | | | 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.

| | | | | | | | | | | Interfaced a lot of the custom tests to the config.cache, in the process made them separate macros and grouped them out into files. Made naming adjustments. Removed a couple of useless/unused configure tests. Disabled C++ by default. C++ is no more special than Perl, Python, and Tcl. And it breaks equally often. :(
