Translate filenames of the form "/c:/*" into just "c:/*" on WinRT and Cygwin. (SQLite has long done this for Win32/WinNT.) check-in: f8470ffc user: drh tags: trunk

Fix lempar.c so that the shift-reduce optimization works for error processing. This is a Lemon issue only and has no impact on SQLite. check-in: 3665a2f5 user: drh tags: trunk

Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree. (3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are combined into a single sqlite3BtreePayloadFetch() routine. The result of these changes is a smaller binary and fewer CPU cycles needed to run queries. check-in: 2d831074 user: drh tags: trunk

Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and make it only work for table btrees. Change sqlite3BtreeDataSize() into sqlite3BtreePayloadSize() and make it work for all btrees. Combine sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single sqlite3BtreePayloadFetch() routine. These changes seem to make the b-tree interface more rational and they reduce both binary size and CPU usage. check-in: bef35e18 user: drh tags: btree-refactor

An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid. The current check-in almost works, but there are still serious issues. check-in: 49638f18 user: drh tags: without-rowid-vtab

Enhance the sqlite3_load_extension() API so that the first parameter (the "db" parameter) can be NULL. An extension that is not associated with any database connection remains loaded for the life of the process. Closed-Leaf check-in: 3a461043 user: drh tags: persistent-extensions

Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. check-in: 37de3eab user: dan tags: trunk
