# There are certain conditions with secure media when the security of
|
||
|
# uploads will need to change depending on the context they reside in.
|
||
|
#
|
||
|
# For example on these conditions:
|
||
|
# * Topic category change
|
||
|
# * Topic switching between PM and public topic
|
||
|
# * Post moving between topics
|
||
|
#
|
||
|
# We need to go through all of the posts in that topic that
|
||
|
# own uploads via access_control_post_id, then for those uploads determine
|
||
|
# if they still need to be secure or not. For example an upload could be
|
||
|
# secure if it is in a PM, and then when the topic gets converted to a public
|
||
|
# topic the upload no longer needs to remain secure as it is no longer in
|
||
|
# a secure context.
