Module InferBase__ResultsDatabase

val database_filename : string

the relative path to the database from the results directory

val database_fullpath : string

the absolute path to the database file

val schema_hum : string

some human-readable string describing the tables

val get_database : unit ‑> Sqlite3.db

The results database. You should always use this function to access the database, as the connection to it may change during the execution (see new_database_connection).

val reset_capture_tables : unit ‑> unit

zero out the tables associated with capture data

val new_database_connection : unit ‑> unit

Closes the previous connection to the database (if any), and opens a new one. Needed after calls to fork(2).

val db_canonicalize : unit ‑> unit

put the database on disk in deterministic form

val db_close : unit ‑> unit

close the current connection to the database

val create_db : unit ‑> unit

create the database file and initialize all the necessary tables

type registered_stmt
val register_statement : ('a, unit, string, registered_stmt) Base.format4 ‑> 'a

Return a function unit -> Sqlite3.stmt that can be called (once the DB has been initialized) to get the prepared statement corresponding to the current DB connection. Use this to prepare statements only once per DB connection.

In particular, clients of this need not worry about calling Sqlite3.finalize on the returned statement, or about generating new statements when the connection to the DB changes: this is all handled internally.

val with_registered_statement : registered_stmt ‑> f:(Sqlite3.db ‑> Sqlite3.stmt ‑> 'a) ‑> 'a
