There are four major code sets in the standard btree source code:
-btree2q.c Single Threaded/MultiProcess with latching supplied by advisory file locking. Works with network file systems.
+btree2s.c Single Threaded/MultiProcess with latching supplied by advisory file locking. Works with network file systems.
-threads2h.c Multi-Threaded/Multi-Process with latching implemented with pthreads/SRW latches in a latch manager.
+threads2h.c Multi-Threaded/Multi-Process with latching implemented by a latch manager with pthreads/SRW latches in the first few btree pages.
-threads2i.c Multi-Threaded/Multi-Process with latching implemented with test & set locks in the btree pages with thread yield system calls during contention.
+threads2i.c Multi-Threaded/Multi-Process with latching implemented by a latch manager with test & set latches in the first few btree pages with thread yield system calls during contention.
-threads2j.c Multi-Threaded/Multi-Process with latching implemented with test & set locks in the btree pages with Linux futex system calls duriing contention.
+threads2j.c Multi-Threaded/Multi-Process with latching implemented by a latch manager with test & set locks in the first few btree pages with Linux futex system calls during contention.
-The Foster set includes three types of latching:
