2014-07-23Report success when Windows kill() emulation signals an exiting process.Noah Misch
This is consistent with the POSIX verdict that kill() shall not report ESRCH for a zombie process. Back-patch to 9.0 (all supported versions). Test code from commit d7cdf6ee36adeac9233678fb8f2a112e6678a770 depends on it, and log messages about kill() reporting "Invalid argument" will cease to appear for this not-unexpected condition.

This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.

Update all files in head, and files COPYRIGHT and legal.sgml in all back branches.
2013-06-28Send SIGKILL to children if they don't die quickly in immediate shutdownAlvaro Herrera
On immediate shutdown, or during a restart-after-crash sequence, postmaster used to send SIGQUIT (and then abandon ship if shutdown); but this is not a good strategy if backends don't die because of that signal. (This might happen, for example, if a backend gets tangled trying to malloc() due to gettext(), as in an example illustrated by MauMau.) This causes problems when later trying to restart the server, because some processes are still attached to the shared memory segment. Instead of just abandoning such backends to their fates, we now have postmaster hang around for a little while longer, send a SIGKILL after some reasonable waiting period, and then exit. This makes immediate shutdown more reliable. There is disagreement on whether it's best for postmaster to exit after sending SIGKILL, or to stick around until all children have reported death. If this controversy is resolved differently than what this patch implements, it's an easy change to make. Bug reported by MauMau in message 20DAEA8949EC4E2289C6E8E58560DEC0@maumau MauMau and Álvaro Herrera

2009-02-15Loop calling CallNamedPipe() several times in case it fails,Magnus Hagander
since it can be transient failures, causing kill() to not properly send signals. Original patch from Steve Marshall, modified by me.

2007-10-23Use snprintf instead of wsprintf, and use getenv("APPDATA") instead ofMagnus Hagander
SHGetFolderPath. This removes the direct dependency on shell32.dll and user32.dll, which eats a lot of "desktop heap" for each backend that's started. The desktop heap is a very limited resource, causing backends to no longer start once it's been exhausted. We still have indirect depdendencies on user32.dll through third party libraries, but those can't easily be removed. Dave Page

2004-12-31Tag appropriate files for rc3PostgreSQL Daemon
Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

2004-08-27Fix Windows emulation of kill(pid, 0). This will now succeed, but onlyTom Lane
if the target PID is a PG postmaster or backend --- for our purposes that is actually better than the Unix behavior. Per Dave Page and Andrew Dunstan.
2004-06-24Include c.h instead of postgres.h in files that need to be usable inTom Lane
both frontend and backend. Per Andreas Pflug.
