@GabrielBrascher removing unused code is good; less is more. These are API calls and related stuff however. A large test set should be run and I am surprised no test code would be touched by this change.

GabrielBrascher · 2016-03-21T13:19:51Z

@DaanHoogland the lack of test in some classes indeed is a problem. However, these classes that I removed are not being used.

I used UCDetector (http://www.ucdetector.org/) as a plugin for Eclipse. With this tool, I discovered a lot of code without any reference (variables, methods and classes).

This pull request had the goal of removing some of these classes. To ensure that I wasn't missing anything I searched for any file that could reference some answer or API command. As I haven't found any way of these classes being used, I removed them.

Any of those API commands that I deleted are not using org.apache.cloudstack.api.APICommand (with @APICommand). Therefore, those commands are not exposed in the ACS API.

DaanHoogland · 2016-03-21T13:25:24Z

Ok, that is somewhat comforting, however still a large integration test suite should be run on this.

swill · 2016-03-21T22:07:42Z

With these major stripping out of unused code, we need to be very careful that we do not introduce integration test issues. Can you please validate that the integration test output does not change based on this code being removed?

GabrielBrascher · 2016-03-21T22:42:28Z

@DaanHoogland @swill thank you for the concern. I agree with the need for executing integration/functional tests to keep the code stable. Unfortunately, our test environment is not set yet and it may take a while. As soon as we have it operational I will run the test.

swill · 2016-03-21T22:46:48Z

Thank you @GabrielBrascher. I am also getting my CI setup so I can get tests running against these PRs, so I should be able to start validating this stuff as well. Thanks for the continued effort. :)

…asses2 Remove classes with no referencesI used UCDetector (http://www.ucdetector.org/) as a plugin for Eclipse. With this tool, I discovered a lot of code without any reference (variables, methods and classes). Following the work that was done at [#1448]; this pull request had the goal of removing some of these classes. To check if I wasn't missing anything I searched for any file that could reference some of those classes. As I haven't found any way of these classes being used, they were removed. Note that some of them I found other references, but references such as commented lines or tests, nothing that could indicate their use (as XML files configuring beans or another class instantiating an object with "new"). Waiting for tests. Please tell me if I am missing something. Removed Classes: - org.apache.cloudstack.framework.jobs.JobCancellationException (**Note:** removed variable JobCancellationException in com.cloud.utils.SerialVersionUID) - org.apache.cloudstack.ldap.NoSuchLdapUserException (**Note:** removed test file /cloud-plugin-user-authenticator-ldap/test/groovy/org/apache/cloudstack/ldap/NoSuchLdapUserExceptionSpec.groovy) - com.cloud.agent.api.storage.CreateVolumeOVAAnswer - com.cloud.exception.MissingParameterValueException - org.apache.cloudstack.api.response.StatusResponse - org.apache.cloudstack.api.response.VolumeDetailResponse - org.apache.cloudstack.api.response.UpgradeVmResponse - org.apache.cloudstack.api.response.AddIpToVmNicResponse - org.apache.cloudstack.api.response.TemplateZoneResponse (**Note:** at org.apache.cloudstack.api.response.TemplateResponse, there is this comment "To avoid breaking backwards compatibility, we still treat a template at different zones as different templates, so not embedding template_zone information in this TemplateZoneResponse set. `private Set<TemplateZoneResponse> zones;`" but right now it is not used) - org.apache.cloudstack.api.response.NicDetailResponse * pr/1453: Removed classes with no reference Signed-off-by: Will Stevens <williamstevens@gmail.com>

 Boolean.class,
 "execute.in.sequence.network.element.commands",
 "false",
- "If set to true, DhcpEntryCommand, SavePasswordCommand, UserDataCommand, VmDataCommand will be synchronized on the agent side."


Also found some reference on the schema-410to420.sql file

Good catch. I will fix that, and create a script to update the database.

LGTM. Verified that classes are unused, just left some minor comment

Can you change this to cloud configuration?

I already did it (https://github.com/apache/cloudstack/pull/1448/files#diff-69537f9fb58dcc5d2b95bb427e8e47e5). I am only creating this script to update that values for environments that already have this entry in the database.

@rafaelweingartner not the comment is to rewrite the update statement as:
UPDATE `cloud`.`configuration` SET ...;

Ah, sure the schema. Done!

yadvr · 2018-10-28T21:26:07Z

Yes @rafaelweingartner test lgtm, the failure are introduced by something else on master. I've left a minor note.
