Hello,

with the upstream release 1.0.27 are some libraray functions
are removed.

According to Debian Policy 8.6.2, renaming of the SONAME and the
library package name is possible for non-backwards compatible ABI
changes.

As the maintainer of this package, I object to the withdrawal
of my changes by the NMU in version 1.0.27-3.1.

Can you please share also some examples of such libraries?
Are them public or private?

this seems legit, if you can prove that the ABI changes are affecting
the public library, I would say that a SONAME change is appropriate.

So far, everybody failed at it...

/me is not RT member, no hat on his head

For sure, we should cleanup symbols file wrt the public/private stuff inside them
(cfr: #911597)

Hello Jörg!

you might feel somewhat lost, at least I'm feeling that way, so I'll try to sum up what changed
(tl;dr, the current status quo seems to be appropriate and I think the package needs no changes right now).

You never answered to what Julien asked you, and his were legit questions:
"libsane was renamed to libsane1 for apparently no good reason.  Renames
for library packages should be tied to ABI breakage (and associated
SONAME changes).

Either there was ABI breakage and the SONAME should be bumped (and
Provides: libsane would be wrong), or there wasn't and the package name
change ought to be reverted."

I get your "hey, the soname was wrong and not matching upstream, change it and now they match" idea, and I think it had good reasons,
but the problem is really another.

You can't just change SONAME if you don't have good reasons to do it, and this was the reason for the whole mess.

The flow chart is usually when an upstream library gets ABI breakages:

1) check for ABI changes and in case upstream SONAME didn't change, well this is an upstream issue, so ask them to release
a new library and bump SONAME.

Bumping it in Debian, without upstream doing it, is a mess, because third party libraries might start crashing if they find the linked library in the system, but with different ABI.

2) if upstream didn't change SONAME, and ABI didn't change, upload as-is


in your case, what happened was a contradicting explanation for the renaming.

You said "ABI changed, so the renaming is appropriate", but you started providing the old binary name in the new one.

This is the error that has been pointed out by Release Team, and no answer has been provided for it (as far as I can see).

Claiming an ABI change, and provide the old package, is a good way to tell apt to not enforce the upgrade of reverse-dependencies, and the best way you can have to make reverse-dependencies crash if that code is run :)

So, to sum up, please provide some clear details about ABI changes, and in that case contact upstream to make them aware of the issue.
Otherwise, the current package might be ok as-is.

thanks for understanding, don't hesitate to contact me also privately in case I missed something, or I didn't explain my reasoning
correctly.

I have build for testing the symbolsfiles from release 1.0.25-4.1
and 1.0.27-4 with --exclude=/sane/ to get only the public symbols.

The resulting diff (diff -Naur symbols_1.0.25-4.1 symbols_1.0.27-4
>1.0.25-4.1_1.0.27-4.diff) is attached.

This diff doesn't look correct.

I've started with 1.0.25, excluding private symbols via

override_dh_makeshlibs-arch:
       dh_makeshlibs -plibsane -X/usr/lib/$(DEB_HOST_MULTIARCH)/sane/ -V

The resulting libsane.symbols is attached.

I then built 1.0.27 with this symbols file, the result is:

dh_makeshlibs: failing due to earlier errors

So, there were quite a few additions (some of them probably shouldn't
be, like the posix_dlsym  and md5_* functions).

The removal of toupper_ascii is strictly speaking an ABI break, but this
never was part of the public API (checking the header files of 1.0.25).
So no bumping the soname for the removal of toupper_ascii is okayish.

Let me add here, that many of those (new) symbols are not part of the
public API as declared in sane.h, so should probably be hidden upstream
or at least marked as optional downstream. The former is preferrable.

Attached is the list of symbols which are part of the ABI but not part
of the public API. Ideally those should not be exported by libsane.so.1

Hello,

I have build the release 1.0.25-4.1 with

override_dh_makeshlibs-arch:
	dh_makeshlibs -X/usr/lib/$(DEB_HOST_MULTIARCH)/sane/  -- -v$(DEB_VERSION_UPSTREAM)  -Pdebian/libsane -plibsane

and the release 1.0.27-4 with

override_dh_makeshlibs-arch:
	dh_makeshlibs -X/usr/lib/$(DEB_HOST_MULTIARCH)/sane/  -- -v$(DEB_VERSION_UPSTREAM)  -Pdebian/libsane1 -plibsane1

and extract the symbols files from the resulting *.deb files.

Both are attached.

The symbols files you attached include the symbols for the backends. You
need to exclude those.
Picking the first symbol in your list as an example:

Given my findings, I'm downgrading the severity as there is not really
an ABI break.

Or another way to investigate this is to use
objdump -T /usr/lib/x86_64-linux-gnu/libsane.so.1.0.27

Seems you have missed what I wrote there or you deliberately ignored it.

Since you bumped it back to serious, can you please elaborate where the
removal of the private symbol is causing issues?
afaics, toupper_ascii should have been marked as optional to begin with.

Quoting man dpkg-gensymbols

Respectfully, the soname was not bumped. If you think that it should
be, why don't you ask the sane-backends developers to do that?

But I agree with the analysis done in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913125#52 and I
think the sane-backends developers will agree that a soname bump isn't
necessary either.

It is unnecessary and unwanted to bump the Debian library package name
when symbols are changed or removed if they are not part of the public
API.

It feels to me like there is widespread agreement that the 1.0.27-3.1
packaging is the best way to handle this (although we should clean up
the symbols files in a future upload). Jörg, what can we do now to
make you happy with this situation so that we can let this version
migrate to Testing and end this dispute we've had for 3 months?

Thanks,
Jeremy Bicha
