ALTER tablets KS validated if RF is not changed by more than 1 for DCs
that already had replicas, but not for DCs that didn't have them yet, so
specifying an RF jump from 0 to 2 was possible when listing a new DC in
ALTER tablets KS statement, which violated internal invariants of
tablets load balancer.
This PR fixes that bug and adds a multi-dc testcases to check if adding
replicas to a new DC and removing replicas from a DC is honoring the RF
change constraints.
Refs: #20039
1. Renamed the testcase to emphasize that it only focuses on testing
changing RF - there are other tests that test ALTER tablets KS
in general.
2. Fixed whitespaces according to PEP8
All current unit tests for scrub in validate mode generate random
SSTables on the fly.
Add some more tests with frozen Cassandra SSTables from the source tree
to verify compatibility with Cassandra. Use some of the existing 3.x
Cassandra SSTables to test the valid case, and use the same schema to
generate some corrupted SSTables for the invalid case. Overall, the new
tests cover the following scenarios:
* valid compressed/uncompressed
* compressed/uncompressed with invalid checksums
* compressed/uncompressed with invalid digest
For the compressed SSTable with invalid checksums, a small chunk length
was used (4KiB) to have more chunks with less disk space. For
uncompressed SSTables the chunk length is not configurable.
Finally, since the SSTables live in the source tree, the quarantine
mechanism was disabled.

The scrub_test_framework, which is the foundation for all scrub-related
tests, always generates a random schema upon initialization and makes it
available to the user. This is useful for running tests with ephemeral
SSTables, but is redundant when the creation of the SSTable predates the
test (e.g., it lives in the source tree).
Turn scrub_test_framework into a template with a boolean parameter to
optionally switch off the random schema generation. Also, add an
overload for run() to support passing a ready-to-use SSTable instead of
mutation fragments.

In a previous patch we extended the validation path of the SSTable layer
to validate the digests along with the checksums.
Add two tests for compressed and uncompressed SSTables to test the
validation API against SSTables with valid checksums but corrupted
digests.
Add two more tests to ensure that the absence of digest does not affect
checksum validation.

Currently, every scrub/validate test is duplicated to cover both
compressed and uncompressed SSTables. However, except for the
compression type, the tests are identical. This leads to some code
bloat.
Introduce common functions parameterized by the compression type to
reduce code duplication. Also, group together the compressed and
uncompressed variants into one compression-agnostic test.

There are two issues in it. First, listing the registry with a consumer callback passes wrong argument to the consumer. Second, the primary key of the registry is wrong. Both issues don't show up, because existing tests that use mock don't read from it, only write. Tests that read from registry are python tests that start scylla and thus use real registry.

This patch adds reproducer tests (still failing) for issue #20755, which
is about missing validation of materialized view names:
1. Unlike table and keyspace names which are limited to 48 characters,
we forgot to limit view name length, and an excessively long name can
cause Scylla to shut down :-(
2. Unlike table and keyspace names which only allow alphanumeric
characters, view names are missing this check and can include any
characters.
3. Luckily, even though we are missing the alphanumeric check, we at
least don't allow "/" in view names (if we allowed them, it could
allow users to write in any directory in the filesystem!). But when
this happens, we get an internal error instead of the expected
errors.
The first test also fails on Cassandra (it doesn't crash it, but leaves
the table in a strange state), but the other two pass.

The one was broken from the very beginning. It only checked that after
creating a table, its directory is created in all datadirs. But it
didn't check that after restart populating happens from the all. That's
because all directories by 0th were always empty, so not-populating from
them didn't skip any data.
Fix it by moving all sstables from datadirs[0] to datadirs[1] before
restart. With that update not-populating data from datadirs[1] will
be noticed instantly. Fortunately, previous patches fixed that, so the
test still passes.

During split prepare phase, there will be more than 1 compaction group with
overlapping token range for a given replica.
Assume tablet 1 has sstable A containing deleted data, and sstable B containing
a tombstone that shadows data in A.
Then split starts:
1) sstable B is split first, and moved from main (unsplit) group to a
split-ready group
2) now compaction runs in split-ready group before sstable A is split
tombstone GC logic today only looks at underlying group, so compaction is step
2 will discard the deleted data in A, since it belongs to another group (the
unsplit one), and so the tombstone can be purged incorrectly.
To fix it, compaction will now work with all uncompacting sstables that belong
to the same replica, since tombstone GC requires all sstables that possibly
contain shadowed data to be available for correct decision to be made.

Following the addition of digest check in the checksummed data source,
add the same feature to the compressed data source as well. This ensures
consistent behavior across any type of SSTable.
This is added as an optional feature so that we can preserve the current
behavior, that is verify only the per-chunk checksums during normal user
reads. To ensure zero cost at runtime when disabled, we introduce the
on/off switch as a template parameter.
The digest calculation for compressed SSTables depends on the SSTable
format, hence the new template argument for the checksum mode. This is
consistent with the compressed data sink.

This is optimization.
Example:
block0: start=aaa, end=aaA
block1: start=bbb, end=bbB
block2: whatever
Before the patch, advance_to("aAA") would skip to block0, and upper
bound probe would skip to block1. This way, the reader would read the
range of block0 from the data file.
After the patch, "end" position is taken into account, so
advance_to("aAA") will notice that block0 doesn't contain the position
and will skip to block1. This is especially important for dense
indexes, as it allows us to skip accessing data file if the search key
is missing.
It also solves the edge case problem related to the fact that single
row reads are using a range which with positions which are not equal
to the key, but are before(key) and after(key) for the lower bound and
upper bound respectively. Before the patch, advance_to(before("bbb"))
would skip to block0, before the position is before the block1's
start. And upper bound probe for after("bbb") would point to
block2. This way the read would scan block0 needlessly. After the
patch, advance_to(before("bbb")) will skip to block1 because we notice
based on "end" that block0 doesn't contain the position.
This change also ensures that the start position of the upper bound
entry of the after_key(pos), where pos is the last advance_to()
position, is warm in cache. This is needed to optimize single-row
reads with a dense index so that they always read exactly one promoted
index block. For this to work, probe_upper_bound() for the
after_key(row) always needs to find the upper bound block in
cache.
Currently, it may happen that the last promoted index block includes
the partition_end marker. That's because we first write the partition
end marker and then emit the unclosed block. This behavior matches
Cassandra (checked in 3.x and 5.0.1).
This is problematic for ruling out data file reads based on index.
The width field is currently unused, but it will be used later where
the width of the last block is used to compute the skip position past
the last block for lookups which land after all keys in the
partition. If width includes the marker then such a skip would land in
the next partition, which is incorrect, as the reader context expects
a cell element. Even if that was recognized, it's wrong - if this is
not a single partition read (so upper bound is not at the next
partition too), then we would read from the wrong (next) partition.
We want to be able to make such skips in order to avoid unnecessary
data file IO for reads of missing rows. Currently, we would always
read the last block even if the key is past its "end" position.
Another way to solve this would be to propagate the "past the last
block" condition from the index cursor to the reader and let it deal
with it, but the logic for that would be complicated. With this fix,
there is no special logic required.

Before these changes, we could create a materialized

This commit makes Scylla respect the option. Now specifying

This way, Scylla's behavior is consistent with Cassandra's.
Because Cassandra doesn't mention the option in its

the semantics of it changes in the future -- we want
to have an open door for any modifications.
Note that Cassandra returns a server error if the provided
ID is already in use, both in the case of regular tables
and MVs. That's most likely a bug. Instead of following that
behavior, we stay consistent with the current semantics of
creating a regular table in Scylla: if the provided ID is
already used, return an InvalidRequest.
The last thing worth pointing out is Cassandra handles
`WITH ID = null` as a special case; normally, specifying
an invalid ID results in a ConfigurationException, but a null
is treated as a syntax error. As in the previous paragraph,
we stay consistent with the semantics of regular tables and
all invalid IDs, null included, lead to a ConfigurationException.
