Item5949: SubscribePlugin problem in canceling subscription to single topic. Results in subscribing to all topics in web.

Test case:

• A topic called MyTestTopic contains a simple tag.
• A user who has no entries in that webs WebNotify topic clicks on the "Subscribe" link. This results in an entry for that user in WebNotify subscribing to MyTestTopic. So far, so good.
• The user now clicks on the "Unsubscribe" link in the same topic. The result is that in the WebNotify topic, they user is now subscribed to all changes in that web and explicitly unsubscribed from the one topic. I.e. the WebNotify entry reads: " * UserName: * -MyTestTopic".

Also, the %SUBSCRIBE% still shows the Unsubscribe link.

BTW, the problem is in MailerContrib.

I can confirm that the fix that Crawford checked in fixes this. I've change the status to "Waiting for release." We just need to publish it.

it's back! :/

i'm closing Item1508 as it turns out to be a duplicate of this bug:

for a given web, when a user removes a topic notification, and that is the last topic listed on the user's line in WebNotify, then the user's line becomes:

UserName:

which causes the user to be notified for any/all changes for the web.

SubscribePlugin should REMOVE the line if there are no more topics to be monitored.

alternatively, redefine what UserName: (nothing) means...

I think that this can be closed. The big difference is the presence of the colon on the subscription line.

• WikiName:<trailing space>
• WikiName:<eol>
• WikiName

The first line with the colon and a trailing space is subscribed to NO topics. Testing mailnotify results in "... web has no subscribers. where as the 2nd line without the trailing space, and the 3rd line without the colon are subscribed to all topics. The SUBSCRIBE macro does properly result in the line with the colon-space - and no topics subscribed when last topic is clicked with unsubscribe.

See also Item11131 for a variation on this - where the user is subscribed via a group.
