* Add initial citus upgrade test
* Add restart databases and run tests in all nodes
* Add output for citus versions 8.0 8.1 8.2 and 8.3
* Add verify step for citus upgrade
* Add target for citus upgrade test in makefile
* Add check citus upgrade job
* Fix installation file path and add missing tar
* Run citus upgrade for v8.0 v8.1 v8.2 and v8.3
* Create upgrade_common file and rename upgrade check
* Add pg version to citus upgrade test
* Test with postgres 10 and 11 in citus upgrade tests
* Add readme for citus upgrade test
* Add some basic tests to citus upgrade tests
* Add citus upgrade mixed mode test
* Remove citus artifacts before installing another one
* Refactor citus upgrade test according to reviews
* quick and dirty rewrite of citus upgrade tests to support local execution.
I think we need to change the makefile in such a way that the tar files can be injected from the circle ci config file.
Also I removed some of the citus version checks you had to not have the requirement to pass that in separately from the pre tar file. I am not super happy with it, but two flags that need to be kept in sync is also not desirable. Instead I print out the citus version that is installed per node. This will not cause a failure if they are not what one would expect but it lets us verify we are running the expected version.
* use latest citusupgradetester in circleci
* update readme and use common alias for upgrade_common import
* Add creating a citus cluster script
Creating a citus cluster is automated.
Before running this script:
- Citus should be installed and its control file should be added to postgres. (make install)
- Postgres should be installed.
* Initialize upgrade test table and fill
* Finalize the layout of upgrade tests
Postgres upgrade function is added.
The newly added UDFs(citus_prepare_pg_upgrade, citus_finish_pg_upgrade) are used to
perform upgrade.
* Refactor upgrade test and add config file
* Add schedules for upgrade testing
* Use pg_regress for upgrade tests
pg_regress is used for creating a simple distributed table in
upgrade tests. After upgrading another schedule is used to verify
that the distributed table exists. Router and realtime queries are
used for verifying.
* Run upgrade tests as a postgres user in a temp dir
postgres user is used for psql to be consistent at running tests.
A temp dir is created and the temp dir's permissions are changed so
that postgres user can access it. All psql commands are now run with
postgres user.
"Select * from t" query is changed as "Select * from t order by a"
so that the result is always in the same order.
* Add docopt and arguments for the upgrade script
Docopt dependency is added to parse flags in script.
Some refactoring in variable names is done.
* Add readme for upgrade tests
* Refactor upgrade tests
Use relative data path instead of absolute assuming that this script will
always be run from 'src/test/regress'
Remove 'citus-path' flag
Use specific version for docopt instead of *
Use named args in string formatting
* Resolve a security problem
Instead of using string formatting in subprocess.call, arguments
list is used. Otherwise users could do shell injection.
Shell = True is removed from subprocess call as it is not recommended
to use this.
* Add how the test works to readme
* Refactor some variables to be consistent
* Update upgrade script based on the reviews
It was possible that postgres server would stay running even when the script
crashes, atexit library is used to ensure that we always do a teardown where we stop
the databases.
Some formatting is done in the code for better readability.
Config class is used instead of a dictonary.
A target for upgrade test is added to makefile.
Unused flags/functions/variables are removed.
* Format commands and remove unnecessary flag from readme
