1.6.0: major soname version decremented?

1.6.0: major soname version decremented?

[Jan Nieuwenhuizen]

While preparing the Guile 1.6.0 release for Cygwin, I found that 1.6.0
produces libguile.so.12.3.0, where Guile 1.5.6 was already at
libguile.so.14.1.0.  This means we'll be getting libguile12 packages
replacing libguile14 packages.

Forgive my ignorance, but shouldn't these version numbers increase
only, with newer releases?

Greetings,
Jan.

Sure, but the 1.5.X releases were just beta releases and shouldn't
have been used publically, and so we don't really make any guarantees
wrt sonames.  i.e. we may break binary compatibility without bumping
the sonames at times, etc.

The reason for the decrement is that Thien-Thi asked that I add some
(libtool) "AGE" to the libraries and that seemed reasonable so I did.
This decremented the major number.

Yes, I know.  But 1.5.x has been stable for almost a year; that's what
we've been using for LilyPond, and that's where (Cygwin compatibility)
development was merged.

Aahh, the wonders of libtool.  You're not telling me that libtool is
in control, rather than the developers? ;-)

But as long as LilyPond didn't deploy a version publically using
1.5.X, then I wouldn't expect there to be a problem...

Nope.  I knew it would decrease the major number, I just didn't think
it would matter.  If this *is* in fact a big problem, please explain,
and we'll figure out what should be done about it.

Yes, I did for Cygwin.  I expect no big problems, though.

No, I think we'll be fine.  Cygwin now has an old libguile14, and a
newer libguile12 package.  By the time that we'll see a new libguile14
package it will get a higher version number than the old one, and the
old one will be replaced automatically.

Naughty, naughty.  (No wonder we were hearing complaints about guile
being too unstable for LilyPond.) :>

OK, good.  Feel free to raise the issue again if this turns out to be
more serious.

That depends on how you look at it.  Guile is now part of the Cygwin
distribution, which is not quite the same as Windows proper.

Visit http://cygwin.com for more information.  Cygwin gives you a
fairly complete unix-like environment for Windows.

Jan.
