From eec08b95e74b6065efa5bc1ea5fd5844e7a95bbd Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Mon, 26 Jan 2004 22:59:54 +0000 Subject: [all] Removed call to getppid in SendPostmasterSignal, replacing with a PostmasterPid variable, which gets set (early) in PostmasterMain getppid would not be the postmaster? [fork/exec] Implements processCancelRequest by keeping an array of pid/cancel_key structs in shared mem [fork/exec] Moves AttachSharedMemoryAndSemaphores call for backends into SubPostmasterMain [win32] Implements reaper/waitpid by keeping an arrays of children pids,handles in postmaster local mem - this item is largely untested, for reasons which should be obvious, but appears sound [win32/all] Added extern for pgpipe in Win32 case, and changed the second pipe call (which seems to have been missed earlier) to pgpipe [win32] #define'd ftruncate to chsize in the Win32 case [win32] PG_USLEEP for Win32 has a misplaced paren. Fixed. [win32] DLLIMPORT handling for MingW case Claudio Natoli --- src/backend/storage/ipc/ipci.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'src/backend/storage/ipc/ipci.c') diff --git a/src/backend/storage/ipc/ipci.c b/src/backend/storage/ipc/ipci.c index 15692684e3..7de7d85e74 100644 --- a/src/backend/storage/ipc/ipci.c +++ b/src/backend/storage/ipc/ipci.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/storage/ipc/ipci.c,v 1.62 2004/01/26 22:54:57 momjian Exp $ + * $PostgreSQL: pgsql/src/backend/storage/ipc/ipci.c,v 1.63 2004/01/26 22:59:53 momjian Exp $ * *------------------------------------------------------------------------- */ @@ -63,6 +63,9 @@ CreateSharedMemoryAndSemaphores(bool makePrivate, size += LWLockShmemSize(); size += SInvalShmemSize(maxBackends); size += FreeSpaceShmemSize(); +#ifdef EXEC_BACKEND + size += ShmemBackendArraySize(); +#endif #ifdef STABLE_MEMORY_STORAGE size += MMShmemSize(); #endif @@ -132,6 +135,13 @@ CreateSharedMemoryAndSemaphores(bool makePrivate, * Set up child-to-postmaster signaling mechanism */ PMSignalInit(); + +#ifdef EXEC_BACKEND + /* + * Alloc the win32 shared backend array + */ + ShmemBackendArrayAllocation(); +#endif } -- cgit v1.2.1
