Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/access/heap
from hub.org:/home/projects/pgsql/tmp/cvs-serv92773/src/backend/access/heap
Modified Files:
heapam.c
----------------------------- Log Message -----------------------------
Add more critical-section calls: all code sections that hold spinlocks
are now critical sections, so as to ensure die() won't interrupt us while
we are munging shared-memory data structures. Avoid insecure intermediate
states in some code that proc_exit will call, like palloc/pfree. Rename
START/END_CRIT_CODE to START/END_CRIT_SECTION, since that seems to be
what people tend to call them anyway, and make them be called with () like
a function call, in hopes of not confusing pg_indent.
I doubt that this is sufficient to make SIGTERM safe anywhere; there's
just too much code that could get invoked during proc_exit().
