While generally better to reduce inline code, here we get
rid of the clustering_interval_set.hh dependency, which in turns
depends on boost interval_set, a large dependency.
incremental_compaction_test.cc is adjusted for a missing header.
Closesscylladb/scylladb#22957
the log.hh under the root of the tree was created keep the backward
compatibility when seastar was extracted into a separate library.
so log.hh should belong to `utils` directory, as it is based solely
on seastar, and can be used all subsystems.
in this change, we move log.hh into utils/log.hh to that it is more
modularized. and this also improves the readability, when one see
`#include "utils/log.hh"`, it is obvious that this source file
needs the logging system, instead of its own log facility -- please
note, we do have two other `log.hh` in the tree.

'static inline' is always wrong in headers - if the same header is
included multiple times, and the function happens not to be inlined,
then multiple copies of it will be generated.
Fix by mechanically changing '^static inline' to 'inline'.
Move mutation-related files to a new mutation/ directory. The names
are kept in the global namespace to reduce churn; the names are
unambiguous in any case.
mutation_reader remains in the readers/ module.
mutation_partition_v2.cc was missing from CMakeLists.txt; it's added in this
patch.
This is a step forward towards librarization or modularization of the
source base.
Closes#12788
This patch switches memtable and cache to use mutation_partition_v2,
and all affected algorithms accordingly.
The memtable reader was changed to use the same cursor implementation
which cache uses, for improved code reuse and reducing risk of bugs
due to discrepancy of algorithms which deal with MVCC.
Range tombstone eviction in cache has now fine granularity, like with
rows.
Fixes#2578Fixes#3288Fixes#10587
Currently the active range tombstone change is validated in the high
level `mutation_fragment_stream_validating_stream`, meaning that users of
the low-level `mutation_fragment_stream_validator` don't benefit from
checking that tombstones are properly closed.
This patch moves the validation down to the low-level validator (which
is what the high-level one uses under the hood too), and requires all
users to pass information about changes to the active tombstone for each
fragment.
Currently, frozen_mutation is not consumed in position_in_partition
order as all range tombstones are consumed before all rows.
This violates the range_tombstone_generator invariants
as its lower_bound needs to be monotonically increasing.
Fix this by adding mutation_partition_view::accept_ordered
and rewriting do_accept_gently to do the same,
both making sure to consume the range tombstones
and clustering rows in position_in_partition order,
similar to the mutation consume_clustering_fragments function.
Add a unit test that verifies that.
Fixes#11198

Memtables and cache will compact eagerly, so tests should not expect
readers to produce exact mutations written, only those which are
equivalant after applying copmaction.
This reverts commit e0670f0bb5, reversing
changes made to 605ee74c39. It causes failures
in debug mode in
database_test.test_database_with_data_in_sstables_is_a_mutation_source_plain,
though with low probability.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
The plan is to move the unstructured content of tests/ directory
into the following directories of test/:
test/lib - shared header and source files for unit tests
test/boost - boost unit tests
test/unit - non-boost unit tests
test/manual - tests intended to be run manually
test/resource - binary test resources and configuration files
In order to not break git bisect and preserve the file history,
first move most of the header files and resources.
Update paths to these files in .cc files, which are not moved.
