Recently I (and probably not only I) got a number of issue tracker letters for old issues (bugs mainly) that they would be closed if no comment on their relevance would be done in a month. I.e. if no one in the Moodle HQ cares about a bug for the year, reporter expected to re-test them on new Moodle version or the bug would be closed. I'm not particulary sure this policy is best. Let's explain.
For me there are two kinds of bug reports: bugs that are particular nasty and really annoy me, and bugs that I just come across and spotted. I usually write bug reports even for the second kind of bugs as a way to give back and free investment to make Moodle better. Such policy makes me an author of quite a lot of bug reports.
Now if the bug is really important in the daily work I'd find time to re-test it on the new Moodle version in the month (we are still using 1.9 due to too many dubious "enhancements" in 2.x versions). But having limited time I may not find enought time and inclination to re-create a tests for rare bugs I just spotted in everyday work on some Moodle installation for the new versions (some bugs require quite an effort to reproduce). So they will be closed, but that doesn't really mean they are fixed. I may not be the only one doing so.
Now, the question for Moodle HQ - did you really want to forget about bug report if an original reporter doesn't have time to re-test it on the new Moodle version? You may lose a useful testing information. And for the bugs I care about, but Moodle HQ is not - would I be expected to re-test each bug every year in similar fashion until someone in Moodle at last look at it?
And question for the bug reporters - how do you feel about new policy and how much of you old bug reports you actually going to re-test?
