What exactly does "attach context" mean in Eclipse Mylyn
eclipse, mylyn
Solution
The Mylyn context is a collection of "landmarks" in your code. A "landmark" is a source file or method, or resource file that is "interesting" (typically means you have opened it when task was active). This article on Mylyn Mylyn 2.0, Part 2: Automated context management may help clear up any confusion on what a context is.
Sharing the context should allow others to see what parts of the code you have been viewing. If you are having issues sharing a context, the Mylyn FAQ on Team support may help.
Problem
the mylyn plugin in Eclipse (Trac connector) contains the option to attach and then retrive the "context" of an issue. Attaching the context results in attaching a zipped XML file to the issue entry in the Trac system. However, I don't quite understand what is this context is. Initially I thought that this was all the opened files and cursor positions in those files. But apparently I was wrong. Searching the net did not help.
