2017-06-29
13:41
Add the stmts virtual table to testfixture builds. Add new compile-time options SQLITE_ENABLE_QPSG and SQLITE_ENABLE_STMTSVTAB to ctime.c check-in: 60c62829 user: drh tags: trunk
13:35
Compilation fix for lsm1 using MSVC. check-in: b7794cc5 user: mistachkin tags: trunk
13:19
Add the LSM1 extension. check-in: 824e8327 user: drh tags: trunk

Add the "stmts" virtual table to the amalgamation, activated when compiled using -DSQLITE_ENABLE_STMTSVTAB. Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN statistics outputs from sqlite3_stmt_status() and add corresponding columns to the stmts virtual table. Change the numeric value of SQLITE_STMTSTATUS_MEMUSED to get it out of the way of counter values. check-in: 88976ae3 user: drh tags: trunk
12:59
