To accomplish this, you must create your changes in +a branch, then {\bf push} them to some public repository -- it can be your +own repository that you publish or another.

This +allows you to modify statuses and close bugs. + +The first thing is if you want to take over a bug, rather than just make a +note, you should assign the bug to yourself. This helps other developers +know that you are the principal person to deal with the bug. You can do so +by going into the bug and clicking on the {\bf Update Issue} button. Then +you simply go to the {\bf Assigned To} box and select your name from the +drop down box. To actually update it you must click on the {\bf Update +Information} button a bit further down on the screen, but if you have other +things to do such as add a Note, you might wait before clicking on the {\bf +Update Information} button. + +Generally, we set the {\bf Status} field to either acknowledged, confirmed, +or feedback when we first start working on the bug. Feedback is set when +we expect that the user should give us more information. + +Normally, once you are reasonably sure that the bug is fixed, and a patch +is made and attached to the bug report, and/or in the SVN, you can close +the bug. If you want the user to test the patch, then leave the bug open, +otherwise close it and set {\bf Resolution} to {\bf Fixed}. We generally +close bug reports rather quickly, even without confirmation, especially if +we have run tests and can see that for us the problem is fixed. However, +in doing so, it avoids misunderstandings if you leave a note while you are +closing the bug that says something to the following effect: +We are closing this bug because ... If for some reason, it does not fix +your problem, please feel free to reopen it, or to open a new bug report +describing the problem". + +We do not recommend that you attempt to edit any of the bug notes that have +been submitted, nor to delete them or make them private.
