Hibernate integration for Jakarta Persistence 3.2 (Jakarta EE 11) on Open Liberty Beta

[Emily-Jiang]

Description

Since Hibernate is driving the Jakarta Persistence 4, it might be the earliest implementation for the next version of Jakarta Persistence. Some customers already use Hibernate with Liberty today by bundling Hibernate with their application. By offering Hibernate as a beta Open Liberty EE 11 Feature, Hibernate will be packaged and integrated by Open Liberty. Liberty team would like to use this feature to get usage and feedback.

Process Overview

• Sizing
• Prioritization
• Design
• Implementation
• Legal and Translation
• Beta
• GA
  • Focal Point Approvals
• Other Deliverables

General Instructions

The process steps occur roughly in the order as presented. Process steps occasionally overlap.

Each process step has a number of tasks which must be completed or must be marked as not applicable ("N/A").

Unless otherwise indicated, the tasks are the responsibility of the feature owner or a delegate of the feature owner.

If you need assistance, reach out to the OpenLiberty/release-architect.

Important: Labels are used to trigger particular steps and must be added as indicated.

Sizing (Complete Before Development Starts)

Sizing features helps inform prioritization decisions by telling us how much investment a given feature will require.

• Feature owner determines the size of the feature.
• Feature owner tells the Open Liberty Project Manager, Release Architect, or Chief Architect what the size of the feature is.

Consider this as the scale to use to gauge sizes:

Size	Guide
XS	<= 1 person week's (PW) worth of work
S	2-3 PW
M	4-5 PW
L	6-9 PW
XL	10-15 PW
2XL	16-20 PW
3XL	21+ PW

---

Prioritization (Complete Before Development Starts)

The OpenLiberty/chief-architect and area leads are responsible for prioritizing the features and determining which features are being actively worked on.

Prioritization

• Feature owner adds label Prioritization - Requested
  • This puts the feature on the radar of the OpenLiberty/chief-architect and OpenLiberty/project-manager. They are responsible for querying for new features that need to be prioritized.
• OpenLiberty/project-manager adds feature to the "New" column of the Open Liberty project board
• Priority assigned
  • Attend the Liberty Backlog Prioritization meeting
  • Prioritization - Requested label removed (OpenLiberty/project-manager or feature owner)

---

Design (Complete Before Development Starts)

Design preliminaries determine whether a formal design, which will be provided by an Upcoming Feature Overview (UFO) document, must be created and reviewed. A formal design is required if the feature requires any of the following: UI, Serviceability, SVT, Performance testing, or non-trivial documentation/ID. Furthermore, each identified item places a blocking requirement on another team so it must be identified early in the process. The feature owner may check-off the item if they know it doesn't apply, but otherwise they should work with the focal point to determine what work, if any, will be necessary and make them aware of it.

Design Preliminaries

• UI requirements identified, or N/A. (Feature owner and UI focal point)
• Accessibility requirements identified, or N/A. (Feature owner and Accessibility focal point)
• ID requirements identified, or N/A. (Feature owner and ID focal point)
  • Refer to Documenting Open Liberty.
  • Feature owner adds label ID Required, if non-trivial documentation needs to be created by the ID team.
  • If seeking No Design approval and the feature requires documentation, verify with the ID team that the doc updates are trivial. If so, add the ID Required - Trivial label.
• Serviceability requirements identified, or N/A. (Feature owner and Serviceability focal point)
• SVT requirements identified, or N/A. (Feature owner and SVT focal point)
• Performance testing requirements identified, or N/A. (Feature owner and Performance focal point)

Governance requests

If work is required in any the following areas for the feature, a request for the Governance Team must be opened for each respective area:

• UI
• ID
• SVT
• Performance

The personnel working in these areas use these issues to prioritize and track work.

Design

• POC Design / UFO review scheduled.
  • Follow the instructions in the README in the POC-Forum repo.
  • Schedule a design review only if the feature has already been prioritized.
• POC Design / UFO review completed.
  • Feature owner adds label Design Socialized
• POC / UFO Review follow-ons completed.
• POC Design / UFO approval requested.
  • Feature owner adds label Design Approval Request
• Design / UFO approved. (OpenLiberty/chief-architect) or N/A
  • (OpenLiberty/chief-architect) adds label Design Approved
  • Add the public link to the UFO in Box to the Documents section.
  • The UFO must always accurately reflect the final implementation of the feature. Any changes must be first approved. Afterwards, update the UFO by creating a copy of the original approved slide(s) at the end of the deck and prepend "OLD" to the title(s). A single updated copy of the slide(s) should take the original's place, and have its title(s) prepended with "UPDATED".

No Design

• No Design requested.
  • Feature owner adds label No Design Approval Request
• No Design / No UFO approved. (OpenLiberty/chief-architect) or N/A
  • Approver adds label No Design Approved
• Feature / Capability stabilization or discontinuation or N/A
  • Feature owner adds label Product Management Approval Request and notifies OpenLiberty/product-management
  • Approver adds label Product Management Approved (OpenLiberty/product-management)
  • Note: For stabilized, superseded, and discontinued feature/capability, skip the Beta section of the template (you may delete it). Otherwise, proceed as normal.

Design Approval Request

Request design approval no later than 4 weeks before the Feature Complete date for the release.

Ideally, submit UFOs for design approval from the Chief Architect as soon as possible after addressing any feedback from the socialization. But that should be no later than 4 weeks before Feature Complete.

That gives the Chief Architect time to review the design and have developers make any necessary updates before the Feature Complete date hits for the release you’re trying to go out in.

See the WebSphere Dates Monday.com board or Current Liberty Release Schedule for relevant dates.

FAT Documentation

• "Feature Test Summary" child task created
  • Use the Feature Test Summary Template
  • Add FTS issue link to the Documents section.

Serviceability Documentation

• "Feature Serviceability Summary" child task created
  • Use the Feature Serviceability Summary Template
  • Add issue link to the Documents section.

Implementation

A feature must be prioritized before any implementation work may begin to be delivered (inaccessible/no-ship). However, a design focused approach should still be applied to features, and developers should think about the feature design prior to writing and delivering any code.
Besides being prioritized, a feature must also be socialized (or No Design Approved) before any beta code may be delivered. All new Liberty content must be inaccessible in our GA releases until it is Feature Complete by either marking it kind=noship or beta fencing it.
Code may not GA until this feature has obtained the Design Approved or No Design Approved label, along with all other tasks outlined in the GA section.

Feature Development Begins

• Add the In Progress label

Legal and Translation

In order to avoid last minute blockers and significant disruptions to the feature, the legal items need to be done as early in the feature process as possible, either in design or as early into the development as possible. Similarly, translation is to be done concurrently with development. All items below MUST be completed before beta & GA is requested.

Innovation (Complete 1 week before Beta & GA Feature Complete Date)

• Consider whether any aspects of the feature may be patentable. If any identified, disclosures have been submitted.

Legal (Complete before Beta & GA Feature Complete Date)

• Changed or new open source libraries are cleared and approved, or N/A. (Legal Release Services/Cass Tucker/Release PM).

Translation (Complete by Beta & GA Feature Complete Date)

• PII (Program Integrated Information) updates are merged (i.e. all English strings due for translation have been delivered), or N/A.

---

Beta

In order to facilitate early feedback from users, all new features and functionality should first be released as part of a beta release.

Beta Code

• Beta fence the functionality
  • E.g. kind=beta, ibm:beta, ProductInfo.getBetaEdition()
• Beta development complete and feature ready for inclusion in a beta release
  • Add label target:beta and the appropriate target:YY00X-beta (where YY00X is the targeted beta version) to the feature issue.

    • Note: This is expected to be done whenever there is new functionality being added for this feature.

      Example scenario: If you are introducing a new feature to the 26.0.0.1-beta release, you would add the target:26001-beta label to the feature issue. Once that beta is released, the target:26001-beta and target:beta labels can be removed from the feature issue. If additional functionality is added to the feature in the 26.0.0.3-beta release, you would re-add the target:beta label as well as the target:26003-beta label to the feature issue. This indicates that there is additional functionality being targeted for a beta release, and which specific beta is being targeted.

• Feature delivered into beta
  • (OpenLiberty/release-manager) adds label release:YY00X-beta (where YY00X is the first beta version that included the functionality).
    • Continuing from the example scenario above, after the 26.0.0.3 beta is released, the feature issue should have the release:26001-beta and release:26003-beta labels on the feature issue. The target:beta label can be removed at this point if there is no additional work being targeted for a beta release.

Beta Blog (Complete by beta eGA)

• Beta blog issue created and populated using the Open Liberty BETA blog post template.
  • Add a link to the beta blog issue in the Documents section.
  • Note: This is for inclusion into the overall beta release blog post. If, in addition, you'd also like to create a dedicated blog post about your feature, then follow the "Standalone Feature Blog Post" instructions under the Other Deliverables section.
  • A feature may have multiple beta blogs associated with it. This is especially useful for features that are continuously adding functionality each release and want to advertise what is new since the previous beta.
    • Each beta blog issue should have the appropriate target:YY00X-beta label added to it.
    • Include each beta blog issue in the Documents section.

---

GA

A feature is ready to GA after it is Feature Complete and has obtained all necessary Focal Point Approvals.

Feature Complete

• Feature implementation and tests completed.
  • All PRs are merged.
  • All related/child issues are closed.
  • All stop ship issues are completed.
• Legal: all necessary approvals granted.
• Innovation: IP identified and any applicable disclosures submitted
• Translation: Feature may only proceed to GA if it has either Translation - Not Required, Translation - Complete, or Translation - Missing label
  • If the feature does not have anything that required translation, the feature owner adds the label Translation - Not Required.
  • If all translation has been delivered to release branch, feature owner adds label Translation - Complete.
  • If missing translation does not cause a break in functionality, nor a security or production outage risk, feature owner adds label Translation - Missing.
    • Once all missing translations are delivered, the Translation - Missing label is replaced with Translation - Complete.
  • If missing translation could cause a break in functionality or a security or production outage risk, feature owner adds the Translation - Blocked label.
    • Features with Translation - Blocked may NOT proceed to GA until the label has been replaced with either Translation - Missing or Translation - Complete.
  • For further guidance, contact Globalization focal point or the Release Architect.
• GA development complete and feature ready for inclusion in a GA release
  • Add label target:ga and the appropriate target:YY00X (where YY00X is the targeted GA version).
  • Inclusion in a release requires the completion of all Focal Point Approvals.
