[atishgoswami]

Preconditions

Project Environment

Magento Version: 2.3.x CE
PHP: 7.2
Database: MySQL 5.7
OS: CentOS 7
Caching: Varnish Cache and OPcache

Steps to reproduce

1. Create a schema patch with a class name e.g. ExampleSchemaPatch
2. Add a logger inside the apply method for the schema patch class to indicate that the apply method was executed
3. Run setup:upgrade
4. Check the patch_list table a fully qualified class name for the patch class would be present
5. Check the log file to confirm that the apply method for the patch was executed
6. Now change the class name of the applied patch to some something else e.g. ChangedExampleSchemaPatch
7. Added the old class name as an array item for the return array for the getAliases() method

public function getAliases()
{
    return [
        ExampleSchemaPatch::class
    ];
}

8. Run setup upgrade one more time

Actual Result

1. The patch gets reapplied. This can be verified by checking the log file
2. A new entry of the renamed patch is added to the patch_list table

Expected Result

The patch should not be reapplied.

Note: This issue can be replicated for Data as well as schema patches
