4fc7be5042 as we have DROP table now, if we want to generate extensional queries eagerly, without affecting how we document interactions with MVCC, we need to travel forward in time and shadow queries eagerly so we can generate queries correctly. This involves cloning the tables unfortunately which is inneficient but correct 2025-10-07 11:38:47 -03:00

46fab87634 Replaced manual validation in SimulatorCLI::validate with Clap features:
- Added `conflicts_with` for mutually exclusive flags
- Removed redundant default values for bool flags.
- Dropped manual validation checks in favor of Clap's built-in parsing guarantees.

860627942a Merge 'core: Rename IO::run_once() to IO::step()' from Pekka Enberg
The `run_once()` name is just a historical accident. Furthermore, it now
started to appear elsewhere as well, so let's just call it IO::step() as
we should have from the beginning.

Closes #3001

8204fbc8ec simulator: Fix 64-bit offset build failures
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.

6591b66c3d Merge 'Simulate I/O in memory' from Pedro Muniz
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 #2785

Closes #2693

d959319b42 Merge 'Use u64 for file offsets in I/O and calculate such offsets in u64' from Preston Thorpe
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
