Add interfaces sqlite3_prepare_v3() and sqlite3_prepare16_v3() with the extra prepFlags argument. Add the SQLITE_PREPARE_PERSISTENT option as one bit in that argument. Use the new option in FTS3, FTS5, and RTREE. (check-in: 03977248e6 user: drh tags: trunk)
2017-06-28
17:29
Instead of the new sqlite3_prepare_v3() interface, provide the SQLITE_DBCONFIG_PREPARE_FLAGS interface which sets the flags on the single next call to sqlite3_prepare_v2() or its cousins. (Closed-Leaf check-in: 942c3ef8cd user: drh tags: dbconfig-prepare-flags)
15:56
Incorporate recent trunk changes. (Closed-Leaf check-in: 62b8269ba2 user: drh tags: prepare_v3)
15:17
Fix harmless compiler warnings in the CSV extension. (check-in: f02a54599d user: drh tags: trunk)

Merge enhancements and fixes from trunk. (check-in: 3fd050c343 user: drh tags: prepare_v3)

# corresponding array entry to be unset.  The default behavior (without
# the -withoutnulls flags) is for the corresponding array value to get

Bytes of payload

    The amount of payload stored under this category.  Payload is the data
    part of table entries and the key part of index entries.  The percentage
    at the right is the bytes of payload divided by the bytes of storage 
    consumed.











Average payload per entry

    The average amount of payload on each entry.  This is just the bytes of
    payload divided by the number of entries.

Average unused bytes per entry

Bytes of payload

    The amount of payload stored under this category.  Payload is the data
    part of table entries and the key part of index entries.  The percentage
    at the right is the bytes of payload divided by the bytes of storage 
    consumed.

Bytes of metadata

    The amount of formatting and structural information stored in the
    table or index.  Metadata includes the btree page header, the cell pointer
    array, the size field for each cell, the left child pointer or non-leaf
    cells, the overflow pointers for overflow cells, and the rowid value for
    rowid table cells.  In other words, metadata is everything that is neither
    unused space nor content.  The record header in the payload is counted as
    content, not metadata.

Average payload per entry

    The average amount of payload on each entry.  This is just the bytes of
    payload divided by the number of entries.

Average unused bytes per entry
