Attempting to read a partition via `SELECT * FROM MUTATION_FRAGMENTS()`, which the node doesn't own, from a table using tablets causes a crash. This is because when using tablets, the replica side simply doesn't handle requests for un-owned tokens and this triggers a crash. We should probably improve how this is handled (an exception is better than a crash), but this is outside the scope of this PR. This PR fixes this and also adds a reproducer test. Fixes: https://github.com/scylladb/scylladb/issues/18786 Fixes a regression introduced in 6.0, so needs backport to 6.0 and 6.1 (cherry picked from commitde5329157c) (cherry picked from commit46563d719f) (cherry picked from commit4e2d7aa2a2) Refs #20109 Closes scylladb/scylladb#20313 * github.com:scylladb/scylladb: test/tablets: Test that reading tablets' mutations from MUTATION_FRAGMENTS works replica/mutation_dump: enfore pinning of effective replication map replica/mutation_dump: handle un-owned tokens (with tablets)

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.
