This is done because the compiler is refusing to inline even after
adding inline hint.
- Get refvalues from directly from registers without using
`make_record`
when updating last_insert_rowid we call return_if_io!(cursor.rowid())
which yields IO on large records. this causes op_insert to insert and
overwrite the same row many times. we need a state machine to ensure
that the insertion only happens once and the reading of rowid can
independently yield IO without causing a re-insert.
Separates cursor.key_exists_in_index() into a state machine. The problem with
the main branch implementation is this:
`return_if_io!(seek)`
`return_if_io!(cursor.record())`
The latter may yield on IO and cause the seek to start over, causing an infinite
loop. With an explicit state machine we can control and prevent this.
Let's make sure we don't keep using a connection after it was dropped.
In case of executing a query that was closed we will try to rollback and
return early.
Was running the sim with I/O faults enabled and fixed some nasty bugs.
Now, there are some more nasty bugs to fix as well. This is the command
that I use to run the simulator `cargo run -p limbo_sim -- --minimum-
tests 10 --maximum-tests 1000`
This PR mainly fixes the following bugs:
- Not decrementing in flight write counter when `pwrite` fails
- not rolling back the transaction on `step` error
- not rolling back the transaction on `run_once` error
- some functions were just being unwrapped when they could suffer io
errors
- Only change max_frame after wal sync's
