What I have learned during recent rebuild of Ruby packages is that the
.specs, which contains conditions to support different versions of
Fedora or EPEL are the one, which are the hardest to maintain. There
is no simple way how to automatically migrate them to support newer
guidelines. This exactly prohibits the innovation. This prohibits any
new feature which we could benefit.
If the .spec would be specific to the Fedora version, it could follow
the latest and greatest development. However there are some version
specific branches which prevent that.
There is no rule prohibiting maintainers from doing so. It's up to a
package's maintainer's discretion.
Yes there is no, that is why this thread started. Limited sharing =>
greater innovation of our packaging => less work for new packages as
well as less learning for newcoming packagers, less possibility for error.
I disagree on the less learning for new packagers, if they package
something that they want on the 4/5 branch available, they'll have to go
through each version of the guidelines.
At the moment we have one set of guidelines which mentions:
Note: for EPEL5, you MUST have a %clean section
Note: for EPEL5 the %defattr is mandatorry
...
If I understand correctly your proposal, to build a package for 4
different branches, I'll have to go through all these branches'
guidelines and find out how they different from devel which is the
mandatory branch.
You have to do it anyway, that is the point. Claiming anything else is
not true. If there is inline note about exception, it makes it even
harder to notice it. You cannot do diff between two guidelines and
really see what is different.
At the moment, there is the main guideline to check and they do mention
what's specific to EL5/EL6. There are not 5 pages mentioning the
guidelines to package for that specific branch.
Yes, if you are not speaking about language specific guidelines, where
it gets interesting.
In addition, we are a community of volunteer, I think we have to be
careful on making their life easier rather than harder and to me, not
having the possibility to merge my changes between branches would make
my life harder.
Yes, that is definitely intention to do your life easier and with every
release of RPM, your life could be easier if you migrate your spec to
the latest greatest features RPM provides, but you don't wan't to. I
can't help you with that, sorry
Well, it might make your life easier for one branch, but not overall.
That's at least my opinion/feeling.
Anyway, we have a difference of opinion here.
What you find unacceptable I find minor or manageable, you really want
different spec per branch, I tend to avoid that as much as I can (even
if I agree, there is a point where having different spec makes sense).
All I can say is that if you bring this proposal to a wider audience,
I'm pretty sure there will be a lot of people feeling the same way.
It is managable if you care just about your packages. I care about Ruby
and hence I care about every other package which depends on Ruby. In
such case it is unmanagable.
And we are speaking about possible changes in RPM, that might affect all
packages in Fedora.
But since you do various branches in one .spec file, the .spec file
becomes un-updatable by script.
The current system allows each maintainer to use the latest version of
the guidelines or to maintain one spec consistent across branches if he
wishes to. I think this is the approach that has the most flexibility
and changing it will crease some feathers.
As well as non-changing it. If beginer takes a look on some hugely
conditionalized .spec file, he will screaming escape. .spec file should
be sort of configuration file, not a script.
