Changes by: tgl(at)svr1(dot)postgresql(dot)org 04/04/21 15:06:30
Modified files:
src/include/storage: buf_internals.h bufmgr.h
src/backend/storage/buffer: buf_init.c bufmgr.c freelist.c
localbuf.c
Log message:
Another round of code cleanup on bufmgr. Use BM_VALID flag to keep track
of whether we have successfully read data into a buffer; this makes the
error behavior a bit more transparent (IMHO anyway), and also makes it
work correctly for local buffers which don't use Start/TerminateBufferIO.
Collapse three separate functions for writing a shared buffer into one.
This overlaps a bit with cleanups that Neil proposed awhile back, but
seems not to have committed yet.
