/*
* LIB/CONFIG.H
*
*
* USE_BSTRING - define if <bstring.h> must be included to get bcopy() and
* related prototypes.
*
*
* NOTE REGARDING USE_SMALL_HASH .. If you wish to set this to continue to
* use small 1 million entry hash tables, set it in lib/vendor.h. As of
* Diablo V1.10, the default dhistory hash table size will be 4 million
* entries.
*
* NOTE REGARDING CHANGING FEATURES: Change these features in LIB/VENDOR.H,
* do *NOT* change these features here unless you are editing this file for
* submission back to me. When adding special features as defaults, the
* operating system version must be explicitly tested.
*
* General notes:
*
* IRIX 6.2 or greater, FreeBSD 2.2 or greater, and Sun/Solaris should
* be able to handle most mmap/shm features, but they have only been tested
* on FreeBSD. Due to the way the code uses READ+WRITE maps, msync()
* is irrelevant so you don't have to worry about that.
*
* All versions of BSDI including 3.0 are known to have serious mmap
* problems even for read-only maps and Diablo may crash the kernel.
*
* Special Features:
*
* USE_PCOMMIT_RW_MAP if mmap() supports shared r+w mmaps, this
* causes diablo to update the precommit cache
* directly rather then with an lseek/write,
* which can reduce filesystem contention.
*
* USE_PCOMMIT_SHM Diablo will use SYSV shared memory for the
* precommit cache. USE_PCOMMIT_RW_MAP is also
* required if you set this option (but it will
* use SYSV shared memory rather then mmap())
*
* USE_SPAM_RW_MAP if mmap() supports shared r+w mmaps, this
* causes diablo to update the spam cache
* directly rather then with an lseek/write,
* which can reduce filesystem contention.
*
* USE_SPAM_SHM Diablo will use SYSV shared memory for the
* spam cache. USE_SPAM_RW_MAP is also required
* if you set this option (but it will use
* SYSV shared memory rather then mmap()).
*
* DO_PCOMMIT_POSTCACHE use the precommit cache as a recent-history
* cache. Suggested only if USE_PCOMMIT_RW_MAP
* or USE_PCOMMIT_SHM are set.
*
*
* USE_ANON_MMAP lib/alloc.c uses MAP_ANON mmap's to allocate
* private memory.
*
* USE_FALL_MMAP lib/alloc.c uses MAP_PRIVATE mmaps on a
* temporary file to allocate private memory.
* (note: the memory winds up being swap-backed
* just like MAP_ANON).
*
* If neither option is set, memory is allocated
* with malloc()/free() but this is not
* recommended if you run more then 10 feeds.
