This is sqlite 3.4.1 This version has some security stuff dealing with the upper bounds of data types. See the change log for more details: http://www.sqlite.org/changes.html#version_3_4_1 -- Shawn Wilsher 08/2007 See http://www.sqlite.org/ for more info. We have a mozilla-specific Makefile.in in src/ (normally no Makefile.in there) that we use to build. To move to a new version: Simply copy the sqlite3.h and sqlite3.c files from the amalgamation of sqlite. Then you need to update sqlite3file.h, which pulls out random bits of the internal files that we need to export. If any of these internal structures change, they need to be changed in sqlite3file.h as well. This may involve downloading the whole souce (not the amalgamation) to check. -- Shawn Wilsher 06/2007 XXX: This is temporarily obsolete (See Bug 385066) You also need to apply preload-cache.patch. This patch provides the preload functionality used by mozIStorageConnection.preload to fill the cache with pages from the disk. -- Brett Wilson 04/2006
