RELEASING NOTES

See SOFTWARE_README.md for commandline scripts. This document covers the larger release process.

Note: These instructions assume the user has sufficient permissions for both github functions and Google Cloud Appengine deployments.

Technical pre-conditions for release

Overview

Code, schema, examples and supporting documentation should be in a stable state.

Pay particular attention to release-specific structures and docs/releases.html (e.g. no stray '2.x', '2.*' etc. in hidden markup or tables)

We declare the current version. This should match the number chosen in /docs/releases.html (check markup assigns an HTML ID too).

The following steps assume a general healthy freeze (tested / QA as below).

in versions.json:

"schemaversion": "3.9",
"releaseLog": {

. . "3.9": "2019-08-01", "3.8": "2019-07-01", } becomes "schemaversion": "4.0", "releaseLog": { . . "4.0": "2019-10-01", "3.9": "2019-08-01", "3.8": "2019-07-01", }

... this should have a release date for the current release and all previous releases that are archived under data/releases/{version}/*

e.g. data/releases/2.1 data/releases/2.1/all-layers.nq data/releases/2.1/core.nq data/releases/2.1/ext-auto.nq data/releases/2.1/ext-bib.nq data/releases/2.1/README.md data/releases/2.1/schema-all.html data/releases/2.1/schema.nt data/releases/2.1/schema.rdfa

PRE-RELEASE STEPS

In a checked out version of the main branch:

  • Successfully run the ./software/util/buildsite.py --release command. This will:

    • assign missing example ids
    • complete a full build of the site, proceeded by tests.
    • copy working copies of release files into data/releases directory

  • The resultant version [to be released] should be committed and pushed to github and CI tests completed successfully.

DEPLOY RELEASE

Use command ./software/gcloud/deploy2schema.org.sh

Note: Supplying the -m option to the deploy2schema.org.sh command will disable the step in the deploy process that migrates web traffic to the newly deployed version. This step can be undertaken manually later via the google cloud appengine console.

Warning: Because of Google cloud caching processes it may take several minutes before new versions of all released files are supplied in response to a browser request. As this includes javascript and css files, initial unusual behavior may be experienced. It is recommended that a full reload of pages, at least 10 minutes after deployment and migration, is performed before analysing a new release.

POST-RELEASE STEPS

  • Tag gitub version vXX.X-release

git tag [tagname] [commmit code]

eg. git tag v14.0-release 9d691a8 Note capitalisation

Then push git push origin [tag name]

After push, release should be auto created and be visible on the repo home page (takes a few minutes)

  • Set up versions.json file for next version - use 2022-XX-XX wildcard date until actual release date confirmed.

GENERAL PRE-Release conditions

  1. General preconditions / process and QA for release.

1-a) Steering Group have signed off on changes and release plan, and no active and unresolved disputes in the Community Group.

1-b) All code is committed to appropriate release branch at Github (usually configured as the current default github branch for /schemaorg/ project).

1-c) All tests pass. It is best to test against a fresh checkout to avoid depending on uncommitted files.

To run tests: ./software/util/runtests.py

Example transcript:

$ git clone https://github.com/schemaorg/schemaorg.git Cloning into 'schemaorg'... ...

.... $ cd schemaorg/ $ ./software/util/runtests.py [...]

Ran 70 tests in 21.168s

OK (expected failures=3)

1-d) Latest candidate release branch is pushed to the generic unstable upstream site (i.e. webschemas.org).

Use command ./software/gcloud/deploy2webschemas.org.sh

1-e) The manual QA page /docs/qa.html has been reviewed to ensure representative pages of each type appear to be in a healthy state.

e.g. see http://webschemas.org/docs/qa.html
