Bug: gateway does not support deleting originalfiles, etc.

Reported by: jamoore Owned by: cxallan
Priority: major Milestone: OMERO-4.4
Component: API Version: n.a.
Keywords: n.a. Cc: python-team@…, jburel
Resources: n.a. Referenced By: n.a.
References: n.a. Remaining Time: 0.0d
Sprint: 2012-01-17 (6)


If we want the gateway to be the one entry point, then we'll need to support more types then these.

~/git/dist/lib/python $ python ../../ 
Traceback (most recent call last):
  File "../../", line 27, in <module>
    handle = g.deleteObjects("/OriginalFile", file_ids, deleteAnns=True)
  File "/Users/moore/GlencoeSoftware.git/git/omero.git/dist/lib/python/omero/gateway/", line 2852, in deleteObjects
    raise AttributeError(m)
AttributeError: /Originalfile is not an object type. Must be: Project, Dataset, Image, Screen, Plate, Well, Annotation

Where is the defined list of what types the delete service supports?

comment:2 Changed 8 years ago by jmoore

It's defined in server/resources/ome/services/delete/spec.xml and can be retrieved via the API with deleteServicePrx.availableCommands().

When deleting the archived image, the archived flag of image must be set to false

Initial implementation which makes deleteObjects() generic is available on my GitHub branch:

Some thoughts which we might want to take into account as a part of a larger story:

  • "graphspec" rather than "delspec": In my 3532-chgrp branch, the delete spec's have been completely refactored to be delete-independent and are now called "graph specs". As always, open to suggestions, but since we will probably be using these in more places (export, etc) it'd make sense to unify the nomenclature. But since that's not present in develop yet, it could certainly wait.
  • new graph api: Similarly in that branch, the delete APIs has been used as the basis for a generalized async API which can also work with other graphs, which prevents us from having to have a new API per async action. Migrating to that would be useful.
  • multiple uses of delete object: In at least one place, IUpdate.deleteObject is being using with tx-safety. Soonish would be a good time to migrate them. (If we need more specs to make that happen, that's fine). For example:
        def removeAnnotations (self, ns):
            Uses updateService to delete annotations, with specified ns, and their links on the object
            @param ns:      Namespace
            @type ns:       String
            for al in self._getAnnotationLinks(ns=ns):
                a = al.child
                update = self._conn.getUpdateService()

All understood Josh. I've made the nomenclature changes so that they are more generic and in line with the incoming branches and #7772 has been created to attempt to address the non-transactional uses of deleteObject(). Closing as now a pull request has been opened:

(In [cd602078226157a2d7af2ea7bc29b3a0e16f2e8a/ome.git] on branch develop) BlitzGateway? deleteObjects() overhaul. (Fixes #7301)

This completely overhauls the deleteObjects() method of BlitzGateway?,
making it more generic and switching to the use of delete specifications
rather than object names. This makes the user have to prefix their
object with a '/' but also teaches them that delete via this mechanism
is more than just deleting an object. The previous object type style is
preserved albeit with deprecation warnings. Furthermore the use of
.title() on the object type has been removed, ensuring that delete
specifications that use mixed case, like '/OriginalFile?', do not break.

(In [384b4d88b1696b1be1b580fd48a496ded14d31b3/ome.git] on branch develop) Refactor unlinkAnnotations to use a single transaction (Fix #7301)

(In [ecb0ab20019cec7e49ac704c540836d768133a9d/ome.git] on branch develop) Merge pull request #63 from chris-allan/7301_delete_ofile

See #7301. Move deleteObjects, removeAnnotations, and unlinkAnnotations to the use of new-style delete, each within a single transaction.
