Tom Lane	0007490e09	Convert the arithmetic for shared memory size calculation from 'int' ... to 'Size' (that is, size_t), and install overflow detection checks in it. This allows us to remove the former arbitrary restrictions on NBuffers etc. It won't make any difference in a 32-bit machine, but in a 64-bit machine you could theoretically have terabytes of shared buffers. (How efficiently we could manage 'em remains to be seen.) Similarly, num_temp_buffers, work_mem, and maintenance_work_mem can be set above 2Gb on a 64-bit machine. Original patch from Koichi Suzuki, additional work by moi.	21 years ago

Tom Lane	eee5abce46	Refactor EXEC_BACKEND code so that postmaster child processes reattach ... to shared memory as soon as possible, ie, right after read_backend_variables. The effective difference from the original code is that this happens before instead of after read_nondefault_variables(), which loads GUC information and is apparently capable of expanding the backend's memory allocation more than you'd think it should. This should fix the failure-to-attach-to-shared-memory reports we've been seeing on Windows. Also clean up a few bits of unnecessarily grotty EXEC_BACKEND code.	21 years ago
Tom Lane	8f6278d907	Put in place some defenses against being fooled by accidental match of ... shared memory segment ID. If we can't access the existing shmem segment, it must not be relevant to our data directory. If we can access it, then attach to it and check for an actual match to the data directory. This should avoid some cases of failure-to-restart-after-boot without introducing any significant risk of failing to detect a still-running old backend.	21 years ago

Tom Lane	5e2b99db95	Avoid assuming that type key_t is 32 bits, since it reportedly isn't ... on 64-bit Solaris. Use a non-system-dependent datatype for UsedShmemSegID, namely unsigned long (which we were already assuming could hold a shmem key anyway, cf RecordSharedMemoryInLockFile).	22 years ago

Tom Lane	f8a769b47a	Cause stats processes to detach from shared memory when started, so that ... they do not prevent the postmaster from deleting the shmem segment during a post-backend-crash restart cycle. Per recent discussion.	22 years ago

Tom Lane	72a3902a66	Create an internal semaphore API that is not tied to SysV semaphores. ... As proof of concept, provide an alternate implementation based on POSIX semaphores. Also push the SysV shared-memory implementation into a separate file so that it can be replaced conveniently.	24 years ago
