Issue With Date Comparisons In Query `-q` Option

by ADMIN 49 views

Introduction

The -q option in the FCLI (Fusion Command Line Interface) is used to filter data based on specific conditions. However, there seems to be an issue with date comparisons in this option. In this article, we will explore the current behavior, expected behavior, and steps to reproduce the issue. We will also discuss possible solutions to resolve this problem.

Current Behavior

The current behavior of the -q option when it comes to date comparisons is not working as expected. The following command is used to demonstrate the issue:

fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-10000d")'

This command is supposed to return application versions that were created within the last 10,000 days. However, the result is an empty array, indicating that the date comparison is not working correctly.

Expected Behavior

The expected behavior of the -q option when it comes to date comparisons is that it should work correctly. The following command should result in a lot of application versions being returned:

fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-10000d")'

Steps to Reproduce

To reproduce the issue, follow these steps:

  1. Create a session with SSC: First, create a session with the SSC (ServiceSphere Console).
  2. Run the command: Run the following command:
fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-1000d")'

This command should return an empty array, indicating that the date comparison is not working correctly.

Environment

The environment in which this issue is observed is not specified.

Possible Solutions

There are two possible solutions to resolve this issue:

  1. Update the expression handler: The expression handler needs to be updated to compare the epoch times of dates and datetimes correctly.
  2. Expose methods from java.time.OffsetDateTime: If it's too difficult to resolve this issue with the expression handler, we can consider configuring SPeL (Spring Expression Language) to expose some methods from java.time.OffsetDateTime. For example, allowing people to call OffsetDateTime.toEpochSecond() would allow people to update date comparisons in the -q option to look like the following:
fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate).toEpochSecond() > #now("-1000d").toEpochSecond()'

Conclusion

In conclusion, the issue with date comparisons in the -q option of the FCLI is a significant problem that needs to be resolved. The current behavior is not working as expected, and the expected behavior is that the date comparison should work correctly. We have discussed possible solutions to resolve this issue, including updating the expression handler and exposing methods from java.time.OffsetDateTime. By resolving this issue, we can improve the functionality of the FCLI and provide a better experience for usersRecommendations

Based on the analysis of the issue, we recommend the following:

  1. Update the expression handler: Update the expression handler to compare the epoch times of dates and datetimes correctly.
  2. Expose methods from java.time.OffsetDateTime: Consider configuring SPeL to expose some methods from java.time.OffsetDateTime to allow people to update date comparisons in the -q option.

Q: What is the issue with date comparisons in the -q option?

A: The issue is that the date comparison is not working correctly in the -q option. The command fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-10000d")' is supposed to return application versions that were created within the last 10,000 days, but it returns an empty array instead.

Q: What is the expected behavior of the -q option?

A: The expected behavior of the -q option is that it should work correctly and return the expected results. In this case, the command fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-10000d")' should return a list of application versions that were created within the last 10,000 days.

Q: How can I reproduce the issue?

A: To reproduce the issue, follow these steps:

  1. Create a session with SSC.
  2. Run the command fcli ssc av ls -o json=id,name,application.name,creationDate -q '#date(creationDate) > #now("-1000d")'.

Q: What are the possible solutions to resolve this issue?

A: There are two possible solutions to resolve this issue:

  1. Update the expression handler: Update the expression handler to compare the epoch times of dates and datetimes correctly.
  2. Expose methods from java.time.OffsetDateTime: Consider configuring SPeL to expose some methods from java.time.OffsetDateTime to allow people to update date comparisons in the -q option.

Q: How can I update the expression handler?

A: To update the expression handler, you will need to modify the code that handles the -q option. This may involve updating the logic for comparing dates and datetimes.

Q: How can I expose methods from java.time.OffsetDateTime?

A: To expose methods from java.time.OffsetDateTime, you will need to configure SPeL to allow access to these methods. This may involve adding a new configuration file or modifying an existing one.

Q: What are the benefits of resolving this issue?

A: Resolving this issue will improve the functionality of the FCLI and provide a better experience for users. It will also allow users to perform date comparisons in the -q option correctly.

Q: How can I get help with resolving this issue?

A: If you need help with resolving this issue, you can contact the support team for assistance. They will be able to provide guidance and support to help you resolve the issue.

Conclusion

In conclusion, the issue with date comparisons in the -q option is a significant problem that needs to be resolved. By understanding the issue, its causes, and the possible solutions, you can take steps to resolve it and improve the functionality of the FCLI. If you need help with resolving this issue,'t hesitate to contact the support team for assistance.
