Item11844: UpdateAttachmentsPlugin breaks TopicInteractionPlugin thumbnails

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Normal	New	Extension	UpdateAttachmentsPlugin

Symptoms

The TopicInteractionPlugin attaching to the the topic thumbnail images like igp_abab3b2631407b50836ccdfb42413d8b_filename.jpg.

When run the update rest handler for the UpdateAttachmentsPlugin, like:

    ./rest /UpdateAttachmentsPlugin/update -topic Sandbox.TestTopic1 -user AdminUser

for the topic, what already contain attachments (with above thumbnails), the UpdateAttachmentsPlugin adds those thumbnails as regular attachments, so getting two attachments:

• one attachment for the original, like filename.jpg
• and another one for generated thumbnail, like igp_abab3b2631407b50836ccdfb42413d8b_filename.jpg

OFC, the TopicInteractionPlugin plugin generating another thumbnail, so get igp_abab3b2631407b50836ccdfb42413d8b_igp_abab3b2631407b50836ccdfb42413d8b_filename.jpg , and so on...

The UpdateAttachmentsPlugin should exclude the igp_ (thumbnail) files when generating the update.

Enhancement idea

The UpdateAttachmentsPlugin should remove the *,v files at the update, when the main file does not exists, so probably those attachments are already removed. If this behavior is dangerous, maybe should be configurable...
