Subject: libgpmg1: Gpm_Event struct expanded

Date: Mon, 31 Mar 2008 11:40:06 +1100

Package: libgpmg1
Version: 1.20.3~pre3-3
Severity: normal

I see the Gpm_Event struct in gpm 1.20.3 has gained new wdx and wdy
fields over what 1.19.6 had.  I think that may be a break of binary
compatility for programs using the low-level library, requiring a bump
of the soname and/or packagename.

Oops, wdx and wdy are not new, they've just moved.  I think that'll
cause problems for programs built against the old and running against
the new, in particular the "type" field has moved, which hurts a program
of mine.

Yes, sorry about that - I haven't really had time to figure out the
best plan to deal with that.  In summary:

- Debian patched libgpm 1.19 a long long time ago, to add those fields,
  among many other changes.  (Without changing the SONAME.  Don't look
  at me, I wasn't involved yet.)  This made Debian libgpm binary
  incompatible with upstream, and we have in fact gotten a few
  complaints about that.

- Upstream 1.20 now has the same fields but they put them in a
  different place.  Now there are 3 different ABIs to worry about,
  without the SONAME of the library having been changed.  Though
  upstream's 2 ABIs are probably backward-compatible since they added
  the fields at the end of the struct.

- Our initial 1.20 release keeps the upstream ordering, hence this bug.
  I've known about it for a long time, I just haven't sat down to
  formulate the best solution.

So, in lenny, we can either be binary compatible with upstream (i.e.,
with Fedora et. al), or we can be binary compatible with sarge and
etch, or we can be incompatible with both (by gratuitously changing our
SONAME).  I'm leaning toward the latter.

I'd suspect not, if the struct grows.  I make it 24 bytes in the
unmodified upstream 1.19.5, now 28 in 1.20, so an old binary would have
space for 24 but Gpm_GetEvent in the new library would plonk 28 there.
There'd be an upstream soname bump for that, would there, maybe ...?

Oh, you don't meant just to libgpm.so.1.20.0?
I think that's still a soname of "libgpm.so.1".

> yes, in 1.20.3 the version bumps

I've just checked and in 1.20.3 the library has the same SOVERSION,
the SONAME is «libgpm.so.1», although the library name is
«libgpm.so.1.20.0». It would be really helpful if you could bump it so
that the SONAME becomes something like «libgpm.so.2», and release a
new upstream version.

I think most of the freezes reported lately are due to that.

Ok no problem, although if you told us what SONAME are you going to
use on the next release, we could go ahead and start the transition,
given that changing SONAME implies changing a package name and the
Debian ftp-masters need to approve this manually, which might take
some time.
