Hi,
The diff from 3.16.2 -> 3.17.0 contains
[[
** table that is being modified.
-** ^The sixth parameter to the preupdate callback is the initial [rowid] of
the
-** row being changes for SQLITE_UPDATE and SQLITE_DELETE changes and is
-** undefined for SQLITE_INSERT changes.
-** ^The seventh parameter to the preupdate callback is the final [rowid] of
-** the row being changed for SQLITE_UPDATE and SQLITE_INSERT changes and is
-** undefined for SQLITE_DELETE changes.
**
+** For an UPDATE or DELETE operation on a [rowid table], the sixth
+** parameter passed to the preupdate callback is the initial [rowid] of the
+** row being modified or deleted. For an INSERT operation on a rowid table,
+** or any operation on a WITHOUT ROWID table, the value of the sixth
+** parameter is undefined. For an INSERT or UPDATE on a rowid table the
+** seventh parameter is the final rowid value of the row being inserted
+** or updated. The value of the seventh parameter passed to the callback
+** function is not defined for operations on WITHOUT ROWID tables, or for
+** INSERT operations on rowid tables.
+**
** The [sqlite3_preupdate_old()], [sqlite3_preupdate_new()],
** [sqlite3_preupdate_count()], and [sqlite3_preupdate_depth()] interfaces
** provide additional information about a preupdate event. These routines
** may only be called from within a preupdate callback. Invoking any of
** these routines from outside of a preupdate callback or with a
]]
I think that last
+** INSERT operations on rowid tables.
Should be
+** DELETE operations on rowed tables.
for it to declare the same undefined behavior on normal tables before and
after 3.17.0.
(I assume the intended change was just documenting the new without rowid
table behavior)
