Bug #4666: set ruby compatibility version to 1.9.3 in trunk
http://redmine.ruby-lang.org/issues/4666

Author: Lucas Nussbaum
Status: Open

ruby -v: 1.9.3


Hi,

(I am one of the Debian maintainers for Ruby)

The trunk branch of Ruby still has a ruby compatibility version of 1.9.1, according to include/ruby/version.h.

The confusion between ruby version and ruby compatibility version caused a lot of questions in the ruby community. Even if 1.9.3 is still binary-compatible with 1.9.1, I think that it would be easier to change its ruby compat version to 1.9.3. This would:
- enable users to co-install (1.9.1 or 1.9.2) and 1.9.3. In debian, 1.9.3 could be provided as a separate ruby1.9.3 package.
- advertise the fact that there are API changes in 1.9.3 that could break apps

Thank you,

There are symbol visibility changes with newer GCC that break
things for extensions relying on functions not declared in
public headers.  I have issue #4328 open for one case I hit.

Extensions relying on accessing members of rb_io_t buffers (exported in
ruby/io.h) won't rebuild under 1.9.3 if they were built for 1.9.2.  No
ABI breakage for already built extensions from the looks of it, though.
ref: r29826[1].

There may be other examples, but I don't remember...


I agree with Lucas that the compatibility version should be raised

Backwards compatibility is too much work if it slows down progress and
improvements that could be made in Ruby 1.9.

The Ruby ecosystem is mostly Free Software and fixable by users.  While
API compatibility is often justified (developer time needed to update
software) and ABI compatibility is /way/ too much work if a rebuild can
fix it.


[1] - My personal take on most structures such as rb_io_t is to make it
      opaque and have stable functions access them, but that's a lot
      of work.

Easier to whom?  You?  You know I have compilers so it's 100% OK for me to
recompile my extension libraries, but I think that's not for everyone --
especially for Windows users.  Even if a Windows user had a compiler (rare!),
recompiling an extension lib is painfully slow on that arch.  So it's not
always "easier".

I know it makes _you_ at ease and I'm not against your motivation.  I hope
there is a good trade-off.

Why do debian have to provide a distro-standard way to have multiple ruby?
That is, why you have to retain 1.9.2 installations once after you have 1.9.3?

> - advertise the fact that there are API changes in 1.9.3 that could break apps

Is this, if any, intentional?  I think such breakage is rather a bug.

I agree with Shyouhei.
The confusion seems to be not for CRuby but for debian's package.

You posted the plan of future debian's package in Apr 2010, and I replied to it.
http://www.mail-archive.com/debian-ruby@lists.debian.org/msg00745.html

Those mails described about this issue and you said as following,
and you finally decided that 1.9.2 will be installed as 1.9.1.

It is your decision, not ours.

I was under the impression that users would be interested in being able
to co-install 1.9.2 and 1.9.3. Of course, if that's not the case, it
changes things a bit.

I agree that we could improve the situation by introducing an additional
ruby1.9.3 package and using symlinks.

However, I am still wondering whether 1.9.3 is really ABI-compatible
with 1.9.{1,2}, which is required if we want to ship it as a drop-in
replacement (same SONAME).

I looked at the symbols exported by libruby.so in 1.9.2 and 1.9.3, and
many symbols were removed (list below). Is that expected? Are they only
symbols that were not supposed to be used by third-party libraries?

Thanks,

- Lucas

[ruby-core:36129] Re: [Ruby 1.9 - Bug #4666][Open] set ruby compatibility version to 1.9.3 in trunk

This is the point.  If we broke binary compatibility already, then it is WRONG
for us to ship 1.9.3 with compatibility version 1-9-1.  I wonder if that
situation (if any) is intentional or just an accident.

I think so.  These symbols are not listed in our C header files.  Until 1.9.2
you needed some tricks to reach to those symbols, like, manually calling
dlsym(3) or something.  I think that is beyond what "binary compatibility" is
meant.

[ruby-core:40047] [Ruby 1.9 - Feature #4666] set ruby compatibility version to 1.9.3 in trunk

[Lucas Nussbaum]

Issue #4666 has been updated by Lucas Nussbaum.


I this that this bug should be closed.

Either the ABI changed between 1.9.2 and 1.9.3, or it did not.

If it changed, then we are required to bump the SONAME, and that means upgrading the ruby compatibility level to 1.9.3.

If it did not change, there's no real interest (even for Debian) in providing co-installation of 1.9.2 and 1.9.3.

According to the discussion, it seems that the ABI should not be considered to have changed, even if some symbols were removed. Hence, let's just close this.

Feature #4666: set ruby compatibility version to 1.9.3 in trunk
http://redmine.ruby-lang.org/issues/4666

Author: Lucas Nussbaum
Status: Third Party's Issue
Priority: Low
Assignee: 
Category: 
Target version: 


Hi,

(I am one of the Debian maintainers for Ruby)

The trunk branch of Ruby still has a ruby compatibility version of 1.9.1, according to include/ruby/version.h.

The confusion between ruby version and ruby compatibility version caused a lot of questions in the ruby community. Even if 1.9.3 is still binary-compatible with 1.9.1, I think that it would be easier to change its ruby compat version to 1.9.3. This would:
- enable users to co-install (1.9.1 or 1.9.2) and 1.9.3. In debian, 1.9.3 could be provided as a separate ruby1.9.3 package.
- advertise the fact that there are API changes in 1.9.3 that could break apps

Thank you,
