I'm not sure how much this will clash with @TcMits's parser rewrite,
hopefully not too much. If it does and we eventually have to remove it,
at least we'll have two new regression tests.
Closes https://github.com/tursodatabase/turso/issues/2484Closes#2499
Use the same rusqlite version in every crate and use a bundled up-to-
date sqlite version
(the impetus for this PR is still me trying to figure out why sqlite in
the insert benchmark doesn't seem to be fsyncing, even when instructed)
Closes#2507
- When the rowid is changed in UPDATE, it is handled as a combination of DELETE + INSERT,
so we dont need to delete the old values in that case
- We should only update the views after the operation on the btree is done
- A proper state machine is needed to handle IO yielding points
Convert Sorter code to use state machines and not ignore completions.
Also simplifies some logic that seemed redundant to me. Also, I was
getting some IO errors because we were opening one file per Chunk, so I
fixed this by using only one file per sorter, and just using offsets in
the file for each chunk.
Builds on top of #2520Closes#2473
I was getting IO errors for too many files when running the simulator
locally. It seemed that the simulator did not delete files after a
successful run. After this change, I did not get anymore errors

Implement very basic views using DBSP
This is just the bare minimum that I needed to convince myself that this
approach will work. The only views that we support are slices of the
main table: no aggregations, no joins, no projections.
* drop view is implemented.
* view population is implemented.
* deletes, inserts and updates are implemented.
much like indexes before, a flag must be passed to enable views.
Closes#2530
Add support for more of the SQLite C API.
Bind functions:
- sqlite3_bind_text (with destructor callback)
- sqlite3_bind_blob
Column functions:
- sqlite3_column_text
- sqlite3_column_blob
- sqlite3_column_bytes
Closes#2528
Currently, we have a borrow problem because parse_schema_rows() already
borrows `schema`, but then `apply_view_deltas` does the same:
```

```
However, this is a read transaction and views are not even enabled,
let's just make `apply_view_deltas()` return early if there's no
processing needed, to skip the schema borrow altogether.
