7 check-ins using file src/btree.c version 0d377e57

Convert sqlite3PagerGet() into a pointer-dispatched virtual method. This makes it about 25% faster. check-in: 7f88bb44 user: drh tags: trunk
18:34
In the pager, avoid checking for the illegal page number 0 except when creating a new page. Closed-Leaf check-in: dee20ba9 user: drh tags: pager-get-method
16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. check-in: 850877d1 user: dan tags: trunk
15:53
Further refinements to the virtual method implementation of sqlite3PagerGet(). check-in: 67df4446 user: drh tags: pager-get-method
14:32
Make the sqlite3PagerGet() interface into a virtual method, with different implementations based on the current state of the pager. This gives a small performance increase by avoiding unnecessary branches inside the various methods. check-in: df5bb90d user: drh tags: pager-get-method

Add the --mmap option to the speedtest1 program and to the speed-check.sh script that is frequently used to run speedtest1. check-in: 1a636d5e user: drh tags: trunk
18:12
Remove unnecessary MemPage initialization resets in the autovacuum ptrmap processing. check-in: 1b36fbb9 user: drh tags: trunk
