Finds core files from correct path on CI. According to default core
pattern on CI, core is generated at the location relative to binary is
executed.
It can be safe to set core pattern before running binary but to change a
kernel param(in our case kernel.core_pattern), you need related
privilege in docker container. Or you have to change it at image build.
But, by default, on CI machines, kernel pattern contains a relative path
to binary + pid + process name, so we do not need to set it explicitly
for now. (Example core file name on CI machine:
`core.2559.!usr!lib!postgresql!14!bin!postgres`)

We have lots of flaky tests in CI and most of these random failures are
very hard/impossible to reproduce locally. This adds a job definition to
CI that allows adding a temporary job to rerun the same test in CI a lot
of times. This will very often reproduce the random failures. If you
then try to change the test or code to fix the random failure, you can
confirm that it's indeed fixed by using this job.
A future improvement to this job would be to run it (or a variant of it)
automatically for every newly added test, and maybe even changed tests.
This is not implemented in this PR.
An example of this job running can be found here:

In PG15, tgisinternal is false in that case. However, we don't want to
create this trigger on the partition since it will create a conflict
when we try to attach the partition to the parent table:

generated columns are silently dropped with the original column.

* Alters public schema's owner to pg_database_owner in PG15
In PG15, public schema is owned by pg_database_owner role.
In multi_extension, we drop and recreate the ppublic schema,
hence its owner become the default user in our tests, postgres.
Change that to pg_database_owner for PG15 consistency.
This results in alternative test output for public schema grants

If a test fails sometimes the diff of the output isn't very helpful. In
those cases looking at the postgres logs can help a lot. We were only
storing these logs as artifacts for arbitrary config tests and tap
tests, now we also store them for our regular test runs.
In CI sometimes failure_setup will fail with the following error:
```diff

```
This then breaks all the tests run after it as well, because we're
missing one worker node.
Locally I was able to reproduce this error by sleeping for 10 seconds in
the forked process sleep before actually starting mitmproxy. So I'm
expecting what's happening in CI is that due to limited resources,
mitmproxy is not up yet when we try to add its port as a workernode.
This PR fixes this by waiting until mitmproxy is listening on its socket
before actually starting to run our tests. This fixed it locally for me
when I made the forked process sleep for 10 seconds before starting
mitmproxy.
In passing it also improves the detection and errors that we already
had for the case where something was already listening on the
mitmproxy port.
Because both @gledis69 and me were changing things in our CI images
at the same time this also includes a bump of the style checker tools.
Closes#6200
For working on initial changes to postgres beta versions make the version check in `./configure` default, but optional.
Normal users will still get the postgres version check error when building on other postgres versions, however, advanced users can use this flag to force configure to pass and find the compilation errors Citus would run into.
Use of the flag is not advised for users not understanding what this does.

This PR makes all of the features open source that were previously only
available in Citus Enterprise.
Features that this adds:
1. Non blocking shard moves/shard rebalancer
(`citus.logical_replication_timeout`)
2. Propagation of CREATE/DROP/ALTER ROLE statements
3. Propagation of GRANT statements
4. Propagation of CLUSTER statements
5. Propagation of ALTER DATABASE ... OWNER TO ...
6. Optimization for COPY when loading JSON to avoid double parsing of
the JSON object (`citus.skip_jsonb_validation_in_copy`)
7. Support for row level security
8. Support for `pg_dist_authinfo`, which allows storing different
authentication options for different users, e.g. you can store
passwords or certificates here.
9. Support for `pg_dist_poolinfo`, which allows using connection poolers
in between coordinator and workers
10. Tracking distributed query execution times using
citus_stat_statements (`citus.stat_statements_max`,
`citus.stat_statements_purge_interval`,
`citus.stat_statements_track`). This is disabled by default.
11. Blocking tenant_isolation
12. Support for `sslkey` and `sslcert` in `citus.node_conninfo`

This PR is fixing 2 separate issues related to the local run of citus upgrade tests.
d3e7c825ab fixes the issue that, with our new testing infrastructure, we moved/renamed some of existing folders. This created a problem for local runs of citus upgrade tests since some paths were sensitive to such changes. This commit tries to make it more generic so that this issue is less likely to happen in the future, while also fixing the current issue.
93de6b60c3 we are fixing an issue that a new environment variable was added for citus upgrade tests, which is defined in the CI. 0cb51f8c37/.circleci/config.yml (L294)
This environment variable wasn't set in our local runs hence it would create problems. Instead of defining this environment variable in the local run, we change the citus_upgrade run command to use an existing env variable, which is now also set in the CI.
There is a vulnerability in mitmproxy with the version we are using.
It would be hard to exploit anything with regards to the artifacts we ship as its only used in our test suite. Still its good hygiene to _not_ use software with known vulnerabilities.
This PR updates the version of python, mitmproxy and the crypto libraries used.
The latest version of mitmproxy for python 3.6 is not patched, hence the upgrade of python.
For our CI images this cascades into upgrading debian as well :)
For CI we bake these versions in our images so we need to update them as well.
Changes to the CI images: https://github.com/citusdata/the-process/pull/65
To run tests in parallel use:
```bash
make check-arbitrary-configs parallel=4
```
To run tests sequentially use:
```bash
make check-arbitrary-configs parallel=1
```
To run only some configs:
```bash
make check-arbitrary-base CONFIGS=CitusSingleNodeClusterConfig,CitusSmallSharedPoolSizeConfig
```
To run only some test files with some config:
```bash
make check-arbitrary-base CONFIGS=CitusSingleNodeClusterConfig EXTRA_TESTS=dropped_columns_1
```
To get a deterministic run, you can give the random's seed:
```bash
make check-arbitrary-configs parallel=4 seed=12312
```
The `seed` will be in the output of the run.
In our regular regression tests, we can see all the details about either planning or execution but this means
we need to run the same query under different configs/cluster setups again and again, which is not really maintanable.
When we don't care about the internals of how planning/execution is done but the correctness, especially with different configs
this infrastructure can be used.
With `check-arbitrary-configs` target, the following happens:
- a bunch of configs are loaded, which are defined in `config.py`. These configs have different settings such as different shard count, different citus settings, postgres settings, worker amount, or different metadata.
- For each config, a separate data directory is created for tests in `tmp_citus_test` with the config's name.
- For each config, `create_schedule` is run on the coordinator to setup the necessary tables.
- For each config, `sql_schedule` is run. `sql_schedule` is run on the coordinator if it is a non-mx cluster. And if it is mx, it is either run on the coordinator or a random worker.
- Tests results are checked if they match with the expected.
When tests results don't match, you can see the regression diffs in a config's datadir, such as `tmp_citus_tests/dataCitusSingleNodeClusterConfig`.
We also have a PostgresConfig which runs all the test suite with Postgres.
By default configs use regular user, but we have a config to run as a superuser as well.
So the infrastructure tests:
- Postgres vs Citus
- Mx vs Non-Mx
- Superuser vs regular user
- Arbitrary Citus configs
When you want to add a new test, you can add the create statements to `create_schedule` and add the sql queries to `sql_schedule`.
If you are adding Citus UDFs that should be a NO-OP for Postgres, make sure to override the UDFs in `postgres.sql`.
You can add your new config to `config.py`. Make sure to extend either `CitusDefaultClusterConfig` or `CitusMXBaseClusterConfig`.
On the CI, upon a failure, all logfiles will be uploaded as artifacts, so you can check the artifacts tab.
All the regressions will be shown as part of the job on CI.
In your local, you can check the regression diffs in config's datadirs as in `tmp_citus_tests/dataCitusSingleNodeClusterConfig`.
There are some libpq changes on postgres side that gives some extra
outputs on the pg13.4 and pg12.8. It is possible that we won't get these
outputs in our local and in those cases it is useful to download those
outputs from the CI.
In order to do that, we store the test results as an artifact in CI.
You can go to artifacts tab in CI to download them.
In our testing infra structure, even though we use pinned versions of postgres, the auxiliary libraries might pull in newer versions. This is for example the case for libpq, which will now use the libpq libraries from 14beta3.
The changes in this PR are a lot due to the libpq changes.
We also have changed the citus version that is used as a base for the citus upgrades, from 10.0 to 10.1 . This caused columnar to enforce some extra limits on the settings, which conflicted with our upgrade tests.
The changes in failure tests are due to the libpq changes.
There are also a lot of changes on isolation tests outputs, hence we
updated all of them.

DESCRIPTION: Add tests to verify crash recovery for columnar tables
Based on the Postgres TAP tooling we add a new test suite to the array of test suites for citus. It is modelled after `src/test/recovery` in the postgres project and takes the same place in our repository. It uses the perl modules defined in the postgres project to control the postgres nodes.
The test we add here focus on crash recovery. Our follower tests should cover the streaming replication behaviour.
It is hooked to our CI for both postgres 12 and postgres 13. We omit the recovery tests for postgres 11 as we do not have support for the columnar table access method.
