Attached are 2 files needed to create a pgkill facility for Windows, and a complementary patch for src/bin/Makefile It is adapted from the facility on the Win32 page, but uses the builtin signal definitions rather than using its own. This facility is needed for shutting down postgres cleanly as part of 'make check', as we don't really use signals in Windows, we only emulate them using our own scheme, so any native kill program doesn't have the desired effect. cheers andrew #------------------------------------------------------------------------- # # Makefile for src/bin/pgkill # # Portions Copyright (c) 1996-2003, PostgreSQL Global Development Group # Portions Copyright (c) 1994, Regents of the University of California # # $PostgreSQL: pgsql-server/src/bin/pgkill/Makefile,v 1.36 2004/04/26 17:40:48 momjian Exp $ # #------------------------------------------------------------------------- subdir = src/bin/pgkill top_builddir = ../../.. include $(top_builddir)/src/Makefile.global override CPPFLAGS := -DPGBINDIR=\"$(bindir)\" -DPGDATADIR=\"$(datadir)\" -I$(libpq_srcdir) $(CPPFLAGS) OBJS= pgkill.o all: pgkill pgkill: $(OBJS) $(CC) $(CFLAGS) $(OBJS) $(LDFLAGS) -o $@$(X) install: all installdirs $(INSTALL_PROGRAM) pgkill$(X) $(DESTDIR)$(bindir)/pgkill$(X) installdirs: $(mkinstalldirs) $(DESTDIR)$(bindir) uninstall: rm -f $(DESTDIR)$(bindir)/pgkill$(X) clean distclean maintainer-clean: rm -f pgkill$(X) $(OBJS) # ensure that changes in bindir etc. propagate into object file pgkill.o: pgkill.c $(top_builddir)/src/Makefile.global Index: src/bin/Makefile =================================================================== RCS file: /projects/cvsroot/pgsql-server/src/bin/Makefile,v retrieving revision 1.43 diff -c -r1.43 Makefile *** src/bin/Makefile 20 Apr 2004 00:40:06 -0000 1.43 --- src/bin/Makefile 10 May 2004 16:17:52 -0000 *************** *** 15,20 **** --- 15,24 ---- DIRS := initdb initlocation ipcclean pg_ctl pg_dump \ psql scripts pg_config pg_controldata pg_resetxlog + ifeq ($(host_os), mingw32) + DIRS := $(DIRS) pgkill + endif + all install installdirs uninstall depend distprep: @for dir in $(DIRS); do $(MAKE) -C $$dir $@ || exit; done #include <stdio.h> #include <stdlib.h> #define WIN32_LEAN_AND_MEAN #include <windows.h> #include <signal.h> #include "pqsignal.h" static void Usage(void) { printf("Usage: pgkill <signal> <pid>\n"); printf("Signal must be uppercase..\n"); exit(1); } static int pgkill(int pid, int sig) { char pipename[128]; BYTE sigData = sig; BYTE sigRet = 0; DWORD bytes; wsprintf(pipename, "\\\\.\\pipe\\pgsignal_%i", pid); if (!CallNamedPipe(pipename, &sigData, 1, &sigRet, 1, &bytes, 1000)) { printf("Failed in call: %ld\n",GetLastError()); return -1; } if (bytes != 1 || sigRet != sig) { printf("Invalid return value!\n"); return -1; } return 0; } int main(int argc, char *argv[]) { int sig = -1; int pid = 0; if (argc != 3) Usage(); if (!strcmp(argv[1],"HUP")) sig = SIGHUP; else if (!strcmp(argv[1],"INT")) sig = SIGINT; else if (!strcmp(argv[1],"QUIT")) sig = SIGQUIT; else if (!strcmp(argv[1],"ABRT")) sig = SIGABRT; else if (!strcmp(argv[1],"KILL")) sig = SIGKILL; else if (!strcmp(argv[1],"TERM")) sig = SIGTERM; else if (!strcmp(argv[1],"USR1")) sig = SIGUSR1; else if (!strcmp(argv[1],"USR2")) sig = SIGUSR2; if (sig == -1) Usage(); pid = atoi(argv[2]); if (pid == 0) Usage(); printf("Got: %i\n",pgkill(pid,sig)); exit(0); }
