I've snipped the rest of your mail, since it's a great task list for the
roadmap to R1. For the immediate next alpha, I believe the above is most
interesting and I would suggest to concentrate on that.
On my laptop, I've seen kernel crashes (I believe all of them have open
tickets). My desktop is running totally stable. The only difference I can
think of is that my Notebook as a supported wireless device, while my desktop
has not. My laptop used to be stable as well, the addition of wireless drivers
is the only thing that changed relative to my desktop. On my desktop though,
which I use more heavily, I've seen issues with running out of memory, without
being able to recover. This issue is also tracked already.
The IRQ routing thing may be our biggest issue. It seems to cause numerous
problems. Other than that, IMHO we should fix the open kernel issues and we
should be good for the next alpha release. I've already expressed my opinion
why I don't believe it's an option to remove the layout and locale API. And
until we go into beta, those don't need to be feature complete.
I was under the impression, that the MTRR issues are now "fixed". I.e. by
ignoring small ranges, we should not run out of MTRR slots so soon.
As far as packaging goes, I am not sure if we need to repackage all packages
like we did for the alpha. I would just rebuild those packages which got
broken by updates to Haiku components.
For libpng, I am not sure if we have a binary compat issue. IIRC, libpng was
provided by BeOS. The library that we now provide as "libpng.so" has a
different ABI. But I am not aware of any apps that directly used this, and
which cannot be rebuilt.
As for creating an alpha 2 branch, I am not sure if we need to do this
immediately. Nobody seems to work on any big features. As long as only bug
fixes go in, or new features that have no possible global impact on stability,
we should be ok with postponing the branching for a while. After all, it does
cause considerable overhead, so it should only be done when necessary.
Best regards,
