Fix relative path references so that make knowns which dependencies refer to one another. Sort out builddir vs srcdir variable namings. Remove some now obsoleted make variables. 2000-08-31 18:12:35 +02:00			`subdir = src/backend/storage/lmgr`

Implement new 'lightweight lock manager' that's intermediate between existing lock manager and spinlocks: it understands exclusive vs shared lock but has few other fancy features. Replace most uses of spinlocks with lightweight locks. All remaining uses of spinlocks have very short lock hold times (a few dozen instructions), so tweak spinlock backoff code to work efficiently given this assumption. All per my proposal on pghackers 26-Sep-01. 2001-09-29 06:02:27 +02:00			`OBJS = lmgr.o lock.o proc.o deadlock.o lwlock.o spin.o s_lock.o`

Move s_lock.c and spin.c into lmgr subdirectory, which seems a much more reasonable location for them. 2001-09-27 21:10:02 +02:00			`s_lock_test: s_lock.c`

Hi, Attached you'll find a (big) patch that fixes make dep and make depend in all Makefiles where I found it to be appropriate. It also removes the dependency in Makefile.global for NAMEDATALEN and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh a little smarter. This no longer requires initdb.sh that is turned into initdb with a sed script when installing Postgres, hence initdb.sh should be renamed to initdb (after the patch has been applied :-) ) This patch is against the 6.3 sources, as it took a while to complete. Please review and apply, Cheers, Jeroen van Vianen 1998-04-06 02:32:26 +02:00			`$(CC) -MM $(CFLAGS) *.c >depend`
