TemporaryHashes.db is a temporary sstable component used during ms sstable writes. It's different from other sstable components in that it's not included in the TOC. Because of this, it has a special case in the logic that deletes unfinished sstables on boot. (After Scylla dies in the middle of a sstable write). But there's a bug in that special case, which causes Scylla to forget to delete other components from the same unfinished sstable. The code intends only to delete the TemporaryHashes.db file from the `_state->generations_found` multimap, but it accidentally also deletes the file's sibling components from the multimap. Fix that. Also, extend a related test so that it would catch the problem before the fix. Fixes scylladb/scylladb#26393 Bugfix, needs backport to 2025.4. - (cherry picked from commit16cb223d7f) - (cherry picked from commit6efb807c1a) Parent PR: #26394 Closes scylladb/scylladb#26409 * github.com:scylladb/scylladb: sstables/sstable_directory: don't forget to delete other components when deleting TemporaryHashes.db test/boost/database_test: fix two no-op distributed loader tests

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
