Fix brekage from first merging commit d959319b ("Merge 'Use u64 for file
offsets in I/O and calculate such offsets in u64' from Preston Thorpe")
and then commit 6591b66c ("Merge 'Simulate I/O in memory' from Pedro
Muniz"), which was unaware of the changes.
Revives the `MemorySim` PR and fixes a page cache issue where we could
have a unlocked and unloaded page in the page cache after a FaultyQuery.
The page would continue in the cache and could affect other queries as
the `page_cache` is at the `Connection` level.
Depends on #2785Closes#2693
Using `usize` to compute file offsets caps us at ~16GB on 32-bit
systems. For example, with 4 KiB pages we can only address up to 1048576
pages; attempting the next page overflows a 32-bit usize and can wrap
the write offset, corrupting data. Switching our I/O APIs and offset
math to u64 avoids this overflow on 32-bit targets
Closes#2791
This kind of fault does not semantically represent anything real,
since we already have fault injection for every concrete IO operation
like reading, writing, syncing and so forth.
Moreover, having this feature is the direct cause of the false positive
simulator failure as reported in issue #2727. There, a "run_once fault"
happened immediately after we fsynced following an INSERT, which caused
the simulator to think the INSERT failed, and later a sim assertion failed
because the on-disk database had 1 more row than it thought it would.
This PR updates to version Rust 1.88.0 ([Release
notes](https://releases.rs/docs/1.88.0/)) and fixes all the clippy
errors that come with the new Rust version.
This is possible in the latest Rust version:
```rust
if let Some(foo) = bar && foo.is_cool() {
...
}
```
There are three complications in the migration (so far):
- A BUNCH of Clippy warnings (mostly fixed in
https://github.com/tursodatabase/limbo/pull/1827)
- Windows cross compilation failed; linking `advapi32` on windows fixes
it
- Since Rust 1.87.0, advapi32 is not linked by default anymore
([Release notes](https://github.com/rust-
lang/rust/blob/master/RELEASES.md#compatibility-notes-1),
[PR](https://github.com/rust-lang/rust/pull/138233))
- Rust is more strict with FFIs and aligning pointers now. CI checks
failed with error below
- Fixed in https://github.com/tursodatabase/turso/pull/2064
