Definition of "Support levels", 1.9.1 supported platforms andrecruitment for platform maintainers

[Yugui (Yuki Sonoda)]

Hi, all.

Ruby committers had the Ruby developers camp 20080811
(http://redmine.ruby-lang.org/wiki/ruby/DevelopersCamp20080811 ). We
talked about platforms which Ruby will support, and decided 4 "support
levels" yesterday.

== support levels
The support levels are "supported", "best effort", "perhaps" and "not
supported". Note that "Platform has a maintainer" includes "Some of core
developers always develop Ruby on it", for example, Debian GNU/Linux.

Supported:
Officially, fully supported. Ruby will be never released while Ruby
has errors on "supported" platforms.

A platform is "supported" when
* The platform has at least one maintainer. One or more maintainer(s)
maintains Ruby on it.
* We can build Ruby for it.
* We can expect that "make test-all" almost succeed.
* We have the nightly build&test environment for it.


Best effort:
We want Ruby to support the platform but some errors occur constantly
on it.
Ruby will be never released while Ruby has serious errors on
"best effort" platforms.

A platform is "best effort" when
* The platform has at least one maintainer.
* We can build Ruby for it.
* We can expect that "make test-all" success except some known
problems.
OR
We have no nightly build&test environemnt for it.

Perhaps:
We think Ruby can work on the platform but it is not officially
supported. Ruby can be released even if Ruby has errors on it.

A platform is "perhaps"
* A similar platform is "supported" or "best effort".

Not supported:
We don't know whether Ruby works on it or not.


== Support plan of Ruby 1.9.1
Supported:
* Debian GNU/Linux 4.0 on IA32
Best effort:
* mswin32, x64-mswin64, mingw32
* Mac OS X (Intel)
* FreeBSD (amd64, IA32)
Perhaps:
* Other Linux distributions
* Mac OS X (PPC)
* mingw64
* cygwin
* Other POSIX compatible systems.
* BeOS (Haiku)
Not supported:
Anything other. But, I think the following platforms can be
"best effort" or "supported" if someone become a maintainer.
* OpenVMS
* WinCE
* OS/2
* bcc32
* Classic MacOS

== Maintainers are wanted
I want someone to become a maintainer and maintains Ruby 1.9 for one of
the following platforms.

These 7 platforms are now "perhaps", they can be "best effort" if a
maintainer appears.
* cygwin
* Interix
* Itanium platforms (Windows, GNU/Linux, ...)
* PPC platforms
* x64 GNU/Linux
* *BSD
* BeOS (Haiku)

These 5 platforms are now "not supported", they can be "best effort" if
a maintainer appears.
* OpenVMS
* WinCE
* OS/2
* bcc32
* Classic MacOS

The tasks which a maintainer should do are:
* Subscribe (e-mail address removed) list.
* Also, subscribe (e-mail address removed) if you can read Japanese.
* Port thread_{win32,pathread}.c to the platform if it has no
implementation of pthread.
* Resolve other build errors and platform specific problems.
* Constantly build and test the trunk version of Ruby on it.
* Effort to succeed in "make test-all" by 20 Dec.

Please send a mail to (e-mail address removed) list and run for a
maintainer if you can.

Regards,

== Support plan of Ruby 1.9.1
Supported:
* Debian GNU/Linux 4.0 on IA32

1. You might want to change that to "Lenny" -- I believe it will be
released/stable before Ruby 1.9.1 is.

2. Most of the Linux distros have Ruby maintainers/herds already, so I
don't think you need to worry about supporting them. And Gentoo builds
from source, so that one is more or less automatic once you release a
source tarball. But I think it's a serious mistake not to support
Fedora. At the very least, you should seriously consider building RPMs
as well as .debs.

These 7 platforms are now "perhaps", they can be "best effort" if a
maintainer appears.
* x64 GNU/Linux

I do builds from source on my Gentoo x86_64 all the time with no trouble
at all. And, as I mentioned above, chances are pretty good it will be in
Gentoo for all of the platforms where it compiles, or at least, it will
be in the Ruby overlay. They've got jRuby and a rather ancient Rubinius
too.

The tasks which a maintainer should do are:
* Subscribe (e-mail address removed) list.
* Also, subscribe (e-mail address removed) if you can read Japanese.
* Port thread_{win32,pathread}.c to the platform if it has no
implementation of pthread.

Is there a Linux distro that *doesn't* have pthread?

* Resolve other build errors and platform specific problems.

As noted above, I do this all the time on Gentoo x86_64. I don't have
any plans to "downgrade" to a 32-bit box anytime soon, although if
you're *real nice*, I might test it on my One Laptop Per Child XO.

* Constantly build and test the trunk version of Ruby on it.

Define "constantly" ... is once a week enough?

* Effort to succeed in "make test-all" by 20 Dec.

Please send a mail to (e-mail address removed) list and run for a
maintainer if you can.

Well ... between me and the Gentoo Ruby herd, I think we can help out.
See https://bugs.gentoo.org/show_bug.cgi?id=203706 for the status of
Ruby 1.9.x on Gentoo.

Hi, all.

Ruby committers had the Ruby developers camp 20080811
(http://redmine.ruby-lang.org/wiki/ruby/DevelopersCamp20080811). We
talked about platforms which Ruby will support, and decided 4 "support
levels" yesterday.

Thanks for this kind of email. It helps me understand the rationale
and process that's going into 1.9.x. I appreciate the efforts by ruby
core.

hi there, we are supporting/maintaining Ruby 1.8 and 1.9 for OSX (intel
and ppc) - for leopard, tiger, panther and also older versions. see the
project site http://rubyosx.com
