This merge just removes LongToken from SkipListMemtable and it replaces it with
a partitioner-agnostic DatabaseDescriptor.getPartitioner().getRandomToken().
The issues in 4.0 / 4.1 are not present in later branches anymore however we
identified that the changes done in 5.0+ are welcome so we included them as well.
Fix estimateRowOverhead in Memtable: ByteBuffer in Partition key was not counted
Fix non-counted size of "columns" field in Columns.unsharedHeapSize
BTree.sizeOfStructureOnHeap wrongly reported a non-zero size for EMPTY_LEAF shared constant value
Fix MemtableSizeTest flakeness by not measuring of allocator and ColumnFamilyStore/Keyspace

nodetool import requires keyspace and table on the command line to import SSTables to. This
was not always working as specifying keypace and table while having SSTables located in the
directory structure which differed on keyspace and table (dir and parent dir) just
ignored them.
patch by Stefan Miklosovic; reviewed by Brandon Williams for CASSANDRA-19401
– ensure test file paths, and their suite names are unique (the latter was broken for cqlshlib and python dtests)
– removal of properties and system-out in test xml happens in CassandraXMLJUnitResultFormatter
– new jenkins agent labels and introduce agents sizes
- ci_summary.html generation script, ref work submitted in apache/cassandra-builds#99
– fix for stress-test and fqltool-test running on small
- ant generate-test-report is limited to only running on individual test types (ci_parser.py provides ci_summary.html for the overview now)
- each cell has a single retry, and the retry will happen on a different agent
- on ci-cassandra the summary stage happens on the builtin, bc copyArtifacts on 15k+ files takes many hours otherwise
- test-burn only needs two splits
- dependency-check is disabled from the lint target until CASSANDRA-19213
- add $DEBUG env var to in-tree scripts, turns on bash debug
- fix FBUtilities' handling of gcp cos_containerd (kernel version comes with a trailing '+' character)

* remove injected exception and tests - not relevant to the current implementation
* expand randomized testing
* inline getCurrent() -> peek(); rename getCount to getMaxKeys
* redefine skipTo contract to not return a value (which saves unnecessary work when skipTo is called multiple times in a row)
* calling hasNext in skipTo is a pessimization; if the iterator is in DONE state, then skipTo will see it and avoid further effort; if it is not, then we are computing a next value that we're just going to throw away

- avoid randomisation to make tests more consistent
- use heap_buffers for VectorDistributedTest for consistency with other tests
patch by Mike Adamson; reviewed by Ekaterina Dimitrova for CASSANDRA-19185
This patch adds a new configuration file, cassandra_latest.yaml, which changes
some of the settings to use new features we usually recommend to users,
including:
- Big Trie-Indexed SSTables
- Trie memtables
- Unified Compaction Strategy
- Storage Attached Index
- Off-heap objects memtables
- Direct-write commit log
- No storage compatibility
These changes are applied in new test targets for unit, in-jvm and python dtests that are
run pre-commit. When changes are made to the new config file, python dtest will use it
directly, but unit and in-jvm dtests require updates, respectively, to latest_diff.yaml
and InstanceConfig.java.

When a node is decommissioned, it triggers data transfer to other nodes.
During this transfer process, receiving nodes temporarily hold token ranges in a pending state.
However, the current cleanup process doesn't account for these pending ranges when calculating token ownership,
leading to inadvertent cleanup of data already stored in SSTables.
To address this issue, this patch introduces two changes.
Firstly, it backports CASSANDRA-16418, introducing a preventive check in `StorageService#forceKeyspaceCleanup`.
This check disallows the initiation of cleanup when a node contains any pending ranges for the requested keyspace.
Secondly, it reintroduces a similar condition to test for the existence of pending ranges in `CompactionManager#performCleanup`.
This ensures the safety of this API as well.

patch by Mick Semb Wever; reviewed by Brandon Williams, Ekaterina Dimitrova, Josh McKenzie, Maxim Muzafarov for CASSANDRA-18665
In this commit the `org.apache.cassandra.io.sstable.CQLSSTableWriter#build` method synchronizes on the
`Schema.instance` object (instead of the `CQLSSTableWriter.class`) to prevent concurrent schema operations
to fail when the offline tools also updates the schema.
For example, a table creation operation, which modifies the keyspace tables metadata, might end up
missing the update when a concurrent call to the `CQLSSTableWriter#build` method is accessing the
singleton Schema instance.
Patch by Francisco Guerrero, reviewed by Yifan Cai, Maxwell Guo, Alex Petrov for CASSANDRA-18317.
There are a couple of fixes in this patch. As explained on the ticket, some of the flaky failures are a race of two events that cause the termination of the connection. First is a legitimate close as a result of expected failures. In this case, the server sends the error message and closes the connection. The test expects to receive that message. However, the test was sending more messages that couldn't be received because the server already closed the connection, and they were bounced by the OS, causing immediate connection shutdown on the client side, even before it could receive the error message.
The fix is to stop sending the messages after sending the message, which is expected to cause a failure. Some other accompanying modifications include using Awaitility to wait for specific events and consider the configured maximum number of consecutive failures.
Also added some more logging to help investigate failures in the future.

This patch removes deprecated chunk_length_kb and sstable_compression in favor of
chunk_length_in_kb and class parameters.
The only deprecated compression parameter left, crc_check_chance (which is configurable outside
of compression parameters as a standalone table parameter) is meant to be treated separately.
patch by Stefan Miklosovic; reviewed by Maxim Muzafarov and Brandon Williams for CASSANDRA-18742
Refactoring prevents the situation where some sstable components, like
data or index, are created before the new sstable is registered with
lifecycle transaction, which leads to a problem such that there is
a short time when incomplete sstable components are present. At the same
time, no transaction file is created, which leads to the possibility
that the sstable can be recognized as completed by various
transaction-aware listers.

Modify unit tests so that any files created are rooted in the directory
specified by the "tmp.dir" Ant property. Ant already passes the value of

to make use of Files.createTempDirectory to generate per-test work
directories. Also update the test checkstyle rules to catch any future
usage of hardcoded "/tmp".

This commit skips the initialization of `topPartitions` in `org.apache.cassandra.db.ColumnFamilyStore`
when running in client or tool mode. The `TopPartitionTracker` class will attempt to query the system
keyspace, which when running in client or tool mode will not be part of the KeyspaceMetadata. This
causes a warning to be printed out with a stacktrace that can be misleading. The warning is similar to
this:
```
WARN org.apache.cassandra.db.SystemKeyspace: Could not load stored top SIZES partitions for ...
org.apache.cassandra.db.KeyspaceNotDefinedException: keyspace system does not exist
at org.apache.cassandra.schema.Schema.validateTable(Schema.java:xxx) ~[?:?]

at org.apache.cassandra.cql3.QueryProcessor.parseAndPrepare(QueryProcessor.java:xxx) ~[?:?]

```
In this commit, we check whether we run in client or tool mode, and skip initialization
of `topPartitions` in those cases.

Notes on the upgrade path:
- RamIndexOutput is replaced with ResettableByteBuffersIndexOutput, an extension of ByteBuffersIndexOutput, which was the closest thing to a replacement of RamIndexOutput.
- Lucene exposes the code we needed from DirectReaders more or less directly in DirectReader now, so the old copied code has been deleted.
- Lucene changed its data files to be little endian, but to keep its compatibility story simple it retained BE for the header and footer ints. That's the cause of the changes in SAICodecUtils.
- We could gain a bit of performance making our own code natively little endian but that is too big of a change for this patch.
