Frozen toolchain updated for the new valgrind dependency.
Allow examining partition and clustering keys, by adding support for
full and prefix compound types. The members of the compound type are
specified by passing several types with --type on the command line.
Currently the available actions are documented in several different
places:
* code implementing them
* description
* documentation for --action
* error message that validates value for --action
This is guaranteed to result in incorrect, possibly self-contradicting
documentation. Resolve by generating all documentation from the handler
registry, which now also contains the description of the action.
Also have a separate flag for each action, instead of --action=$ACTION.
We often have to examine raw values, obtained from various sources, like
sstables, logs and coredumps. For some types it is quite simple to
convert raw hex values to human readable ones manually (integers), for
others it is very hard or simply not practical. This command-line tool
aims to ease working with raw values, by providing facilities to print
them in human readable form and compare them. We can extend it with more
functions as needed.
Examples:
$ scylla_types -a print -t Int32Type b34b62d4
-1286905132
$ scylla_types -a compare -t 'ReversedType(TimeUUIDType)' b34b62d46a8d11ea0000005000237906 d00819896f6b11ea00000000001c571b

The xxhash library has been packaged by Fedora, so we can use it
instead of carrying the submodule. This reduces allows us to
receive updates as the OS packages are updated. Build time will
not be reduced since it is a header-only library.
xxhash preserves the hash results across versions so rolling
upgrades will still work.
The frozen toolchain is updated with the new package.
Tests: unit (dev)
podman is compatible with docker, but by default emits a manifest
format that is not understood by old docker clients, so give it
an extra flag to generate the old format instead.

Specify --pull in order to refresh the base image (some Fedora release).
Usually this is not important, because we run `dnf update`. But if the
cached image happens to be a pre-release version of Fedora, the image
will have the update-testing repository enabled, and we may get some
unwanted updates.
It's sad that we need two separate flags for correctness (the other
is --no-cache.

To run Alternator tests, only two additional dependencies need to be added to
install-dependencies.sh: pytest, and python3-boto3. We also need
python3-cassandra-driver, but this dependency is already listed.
This patch only updates the dependencies for Fedora, which is what we need
for dbuild and our Jenkins setups.
Tested by building a new dbuild docker image and verifying that the
Alternator tests pass.

Since we now default to lld if present, and since lld is a faster
linker than either ld or gold, it makes sense to install it
as a dependency and to make it available as part of the frozen
toolchain.
Docker restricts the number of processes in a container to some
limit it calculates. This limit turns out to be too low on large
machines, since we run multiple links in parallel, and each link
runs many threads.
Remove the limit by specifying --pids-limit -1. Since dbuild is
meant to provide a build environment, not a security barrier,
this is okay (the container is still restricted by host limits).
I checked that --pids-limit is supported by old versions of
docker and by podman.
Fixes#5651.

This reduces network traffic and eliminates time for installation when
building packages from the frozen toolchain, as well as isolating the
build from updates to those dependencies which may cause breakage.

Just letting "docker run" fail produces kinda confusing error message,
referring to docker help, but the we want to provide the user
with our own help, so still fail early, just also try to pull the image
if "docker image inspect" failed, indicating it's not present locally.

podman needs to relabel directories in exactly the same cases docker
does. The difference is that podman cannot relabel /tmp.
The reason it was working before is that in practice anyone using
dbuild has already relabeled any directories that need relabeling,
with the exception of /tmp, since it is recreated on every boot.

Docker on Fedora 31 is flakey, and is not supported at all on RHEL 8.
Podman is a drop-in replacement for docker; this series adds support
for using podman in dbuild.
Apart from actually working on Fedora 31 hosts,
podman is nicer in being more secure and not requiring a daemon.
Fixes#5332
At least some versions of 'podman logs --follow' hang when the
container eventually exits (also happens with docker on recent
versions). Fortunately, we don't need to use 'podman logs --follow'
and can use the more natural non-detached 'podman run', because
podman does not proxy SIGTERM and instead shuts down the container
when it receives it.
So, to work around the problem, use the same code path in interactive
and non-interactive runs, when podman is in use instead of docker.
With docker, we went to considerable lengths to ensure that
access to mounted volume was done using the calling user, including
supplementary groups. This avoids root-owned files being left around
after a build, and ensures that access to group-shared files (like
/var/cache/ccache) works as expected.
All of this is unnecessary and broken when using podman. Podman
uses a proxy to access files on behalf of the container, so naturally
all access is done using the calling user's identity. Since it remaps
user and group IDs, assigning the host uid/gid is meaningless. Using
--userns host also breaks, because sudo no longer works.
Fix this by making all the uid/gid/selinux games specific to docker and
ignore them when using podman. To preserve the functionality of tools
that depend on $HOME, set that according to the host setting.
podman refuses to start with duplicate volumes, which routinely
happen if the toplevel directory is the working directory. Detect
this and avoid the duplicate.
This is a minor update as gcc and boost versions do not change.
glibc-langpack-en no longer gets pulled in by default. As it is required
by some locale use somewhere, it is added to the explicit dependencies.
Update previous results dictionary using the update_metrics method.
It calls metric_source.query_list to get a list of results (similar to discover()) then for each line in the response it updates results dictionary.
New results may be appeneded depending on the do_append parameter (True by default).
Previously, with prometheous, each metric.update called query_list resulting in O(n^2) when all metric were updated, like in the scylla_top dtest - causing test timeout when testing debug build.
(E.g. dtest-debug/216/testReport/scyllatop_test/TestScyllaTop/default_start_test/)

"
In this patch set, written by Piotr Sarna and myself, we add Alternator - a new
Scylla feature adding compatibility with the API of Amazon DynamoDB(TM).
DynamoDB's API uses JSON-encoded requests and responses which are sent over
an HTTP or HTTPS transport. It is described in detail on Amazon's site:
https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/
Our goal is that any application written to use Amazon DynamoDB could
be run, unmodified, against Scylla with Alternator enabled. However, at this
stage the Alternator implementation is incomplete, and some of DynamoDB's
API features are not yet supported. The extent of Alternator's compatibility
with DynamoDB is described in the document docs/alternator/alternator.md
included in this patch set. The same document also describes Alternator's
design (and also points to a longer design document).
By default, Scylla continues to listen only to Cassandra API requests and not
DynamoDB API requests. To enable DynamoDB-API compatibility, you must set
the alternator-port configuration option (via command line or YAML) to the port on
which you wish to listen for DynamoDB API requests. For more information, see
docs/alternator/alternator.md. The document docs/alternator/getting-started.md
also contains some examples of how to get started with Alternator.
