Context

2008-03-10
16:17		Remove the #includes of stdlib.h and sys/types.h from sqliteInt.h since they are never used and because they broke the build. (CVS 4851) (check-in: 2668000f user: drh tags: trunk)
14:12		Add explicit !=0 tests in order to suppress warning messages in Borland-C. Ticket #2985 (CVS 4850) (check-in: d4ab14b9 user: drh tags: trunk)
2008-03-09
02:51		Fix for #2981 - specifically use "tclsh8.4" if it's available (CVS 4849) (check-in: 8ced1d64 user: mlcreech tags: trunk)

Changes to src/pager.c.

** atomic commit and rollback through the use of a journal file that
** is separate from the database file.  The pager also implements file
** locking to prevent two processes from writing the same database
** file simultaneously, or one process from reading the database while
** another is writing.
