[Qemu-devel] release date of qemu 0.9.2?

Hash: SHA1

When will qemu be given the status of 0.9.2?  I was browsing the  
source code of the Qemu that ships with OpenSuSE and noticed that  
there are a lot of patches.  It would probably be helpful if there was  
a release that didn't depend on GCC 4.

Also, what targets still depend on dyngen?  And is anyone working on  
porting them to TCG?

You probably meant gcc 3 which is a requirement for dyngen targets.

Only PowerPC targets still depend on dyngen, and it's being worked on.

Only PowerPC depends on dyngen. I am currently working on converting it
to TCG as my free time allow it, and a few other persons are also
sending patches. I expect that the conversion will be finished in about
one month (this target has a high number of existing dyngen-ops due to
the number of supported CPU with specific extensions).

Unfortunately that also means I will spend less time on merging patches
from the mailing-list.

A lot of previously supported hosts are no longer supported with TCG.  I 
would think adding those hosts would be more important than completing 
the TCG conversion before cutting a new release.

I disagree. The most important hosts are supported, the other hosts
were largely experimental anyway, and getting rid of dyngen / gcc3
is IMHO worth a release.

Personally, I'd like to see much more frequent releases (every 3-6 
months).  I'm okay with not having complete features (like the 
dyngen->TCG conversion) or host regressions because I think there's 
value in having releases regularly compared to feature based releases.

What do other people think?  I'd be willing to do the leg work of releases.

I believe there's a lot of users who grab the stable releases, but
won't grab the development snapshots.
So usually releasing official releases more often means more testing happening.

I believe it's worthy.

I agree with you I think that the kernel way of release is good and can be
used for qemu

I agree with Thiemo. Removing dyngen is more important than new TCG host 
support.

Cutting releases is the easy. Making sure the tree is in a suitable state to 
be released is the hard bit.  Releases without good quality control are IMHO 
pointless.

Given the speed of qemu development, I think 3 months is way too short for a 
release cycle.  You may as well just have everyone pull from SVN.

The kernel has too many -rcX , which I believe does not suit qemu well.
This is because of the size of the user and developer base. The merge window is
also something that we would have a hard time doing without a distribuited scm.

So, kernel + adaptations is fine.

Yeah, what I meant by leg work was doing deep testing and nagging people 
to fix things up before a release.  Cutting a release is very simple.

How do you feel about 6 months?

I think switching to a hard time driven release schedule would be a mistake.
In particular I think we should complete the TCG conversion before the next 
release.

That said, 6 months between releases may be a reasonable starting point.

Shouldn't it be feature driven rather then time?

Yes, I was thinking that to start with aiming for 6 month release

Agreed, 6 months sounds like it will catch enough worthwile features
for a new release.

Personally I'd appreciate a decision process involving the community,  
e.g. a last call for patches period before doing the release.

Something to consider is that distros would probably prefer maintained  
releases over frequent releases. Now that we've switched to SVN, it  
would be possible to branch for a release (not just tag it) and to  
apply security/build fixes to the branch so that distros/users can  
pull from here rather than from an external location like Launchpad.  
In that case, branching more often could mean more legwork maintaining  
branches.

Andreas
