Re: Bug in Panther HID support for Powerbook keyboards



Hi Garth,

Is this a known bug?

If not (or if an additional report will make a difference), I will report it in radar.

There's no need to worry about whether a problem is known or not. Just file the bug report, including everything needed for us to reproduce the problem. A large number of related reports can tell us how widespread a problem is.

I can see why at your end there is no reason to worry whether a bug is know or not. For me, as a developer it does make a huge difference for several reasons:


1) It could be that I am wrong and that it is no bug but an error on my end or a "feature" that behaves as expected (no need to write it up in these cases).

2) If it is a know bug a workaround may also be available. if I just file the bug it can take weeks if not months before someone tells me it is a known bug and that there is an easy work around.

3) If it is a known bug it could be that it is already fixed for a future release. No need for me to write up a bug report in that case.

4) If it is not just a know but a well known bug chances are that adding yet another report is not going to make much of a difference.

5) If it is an unknown bug or one not going to be prioritized (because Apple deems it low priority) unless many people write in bug reports on it then it is worthwhile writing up a report.

6) Writing up a report for a known bug may be useful to prioritize it but it is very ungratifying for a developer to write up such a bug because it will be marked as a duplicate and the developer will not be kept informed if and when the bug will be fixed nor can he see anything in radar but the fact that it is a duplicate. The only way to find out about the progress on a duplicate is to write into devbugs and ask. that is not something anyone would want to do weekly or so as it waistes everyones time and bandwidth.

7) Writing up a good bug report "including everything needed for us to reproduce the problem", as you state it, takes quite a bit of time and may even involve making a sample project to demonstrate the issue. Writing up a good bug report can take anywhere from 15-30 minutes to a couple of hours depending on the issue. I would happily invest that time if I know it will make a difference, but not if it is not neccesary for one of the reasons mentioned above. Or, in case it is a known issue that can use some more priotarization, I would write up a minimal report in 5-10 minutes without all the detailed documentation needed to isolate a new issue.

Anyway, to make a long story short I have just reported the bug as Bug ID 3524888.

Is it possible that you somehow got the cookies reversed for the two keys?

I don't think so. I lookup the relation between cookies and usage values on the fly after the user selects a particular keyboard to work with. Also, the problem does not occur with an external keyboard only with the build in Powerbook keyboard.


Instructions to reproduce the problem are in my bug report (Bug ID 3524888).

At this point for me the most important thing to know is whether this is likely to be a problem only with the built-in keyboards of the powerbooks, or also with the iBooks or even with all ADB keyboards. I don't have the machines available to test this but it would be worthwhil knowing this in order to create a temporary workaround.

Thanks,

david.
