Backlinks for tickets in comment history


This plugin automatically creates intra-Trac references between tickets. Example: when a comment on ticket A references ticket B, a comment is made on ticket B letting you know that ticket A has referenced it.

Adding the following comment in ticket A (in casu 39):

Results in the following trackback in ticket B (in casu 67):

Note: This plugin will not retroactively create trackbacks for existing comments.

Usage scenario

If developer A is working on ticket 1 and developer B is working on ticket 2 and writes some notes (on ticket 2) how it's related to ticket 1, it automatically makes a (ticket-2)-to-(ticket 1) link that's easy to follow to get more details. So far so good. However, developer A has no idea her ticket has just been discussed on ticket 2, and tinkers on blithely unaware of what is going on around her, because there is no reciprocal (ticket 1)-to-(ticket 2) link.

How can we automatically indicate that tickets are being discussed at other tickets? This plugin creates that reciprocal (ticket 1)-to-(ticket 2) link so that anyone looking at ticket 1 can see it has been talked about on ticket 2 as well.

close #9008 -- In the event that the changelog is empty, cnum_thischange needs to be set to the string "1", not the integer 1

ticket.get_changelog() returns entries that aren't comments (as well as entries that are comments) -- so, if the latest modification on the ticket does not have a comment, tracbacks will cause an internal error by assuming an incorrect data structure. this commit fixes the problem by filtering out all changelog entries that are not comments. (fixes #9743)
