1.28.0rc2

Release Candidate

This is a release candidate! Only to be used in testing environments!

Upgrade Instructions

This feature release requires a database schema upgrade. Please consult the documentation about upgrading your database schema.

The following changes are necessary and are covered by the alembic upgrade head command:

  1. Introduction of the transfer_hops table for the transfer system. (Alembic revision 0f1adb7a599a)

  2. third_party_copy_read and third_party_copy_write replace the third_party_copy priority for protocols (rse_protocols table) (Alembic revision fe1a65b176c9)

    • Introduction of default values for third_party_copy_read and third_party_copy_write (rse_protocols table)

    • Migrate script copies third_party_copy values to the third_party_copy_read and third_party_copy_write column

    • third_party_copy column will be removed from the table at a later release

Important changes

  • This release drops the gfalv2 protocol implementation which is replaced by the gfal.NoRename protocol.

  • In case you run multiple releases (e.g. 1.28.0rc1 for integration, 1.27.X in production) in your Rucio deployment, please be aware that this release is in general incompatible with older releases, due to the changes in the transfer machinery. Such a mixed production/integration deployment will only be possible with the Rucio 1.27.11 release.
