Hi,

I'm not perfectly convinced about this RM request, but something should
happen with openchange in stable:

* openchangeproxy (1:2.2-5) is uninstallable in stable (#838671)
samba-libs has a Breaks: openchangeproxy (<< 1:2.2-6) that stems from
the first samba 4.2 upload to jessie-security:

samba (2:4.2.10+dfsg-0+deb8u1) jessie-security; urgency=high

* Revert the change to made libsamba-debug a library, allowing openchange
to link to Samba 4.2
* Add Breaks against openchangeproxy that uses an API and ABI that has changed

* openchange FTBFS in stable (I just mentioned this in #838671)
(the version in stable was most likely built against samba 2:4.1.13+dfsg-4)

* openchange was removed from unstable due to incompatibility with
newer samba versions

* downside: openchange builds a lot more packages than just openchangeproxy
these are all still installable in stable (according to piuparts)

At $work we rely on openchange but not openchangeproxy. We know it was
removed from stretch and later but were assuming we could use it on
jessie, once we have migrated from wheezy. The wheezy to jessie
migration is blocked by some regression bugs in jessie Linux CIFS
support that we are in the process of debugging. Once we have fixed
that, we would like to start migrating systems to jessie. Post-jessie
we don't yet have a strategy but are looking into options.

I guess this could be fixed by a new upload that either drops
openchangeproxy or fixes the API/ABI usage.

This looks like the API issue in openchangeproxy mentioned in the
samba changelog from the build log messages you posted.

This is the openchange bug and patch for this specific FTBFS:

https://github.com/openchange/openchange/issues/249
https://github.com/openchange/openchange/commit/73a49af50bf0a496cfe62f49e60a662f1d04d685.patch

Unfortunately the openchange project is dead upstream so it won't be
coming back.

At $work we rely on openchangeclient and several of the -dev packages.

I've tested that this fixes the FTBFS in openchange.

I'm unable to test that openchangeproxy still works but the patch looks
like a fairly straight forward update to the newer samba APIs.

The rest of the binary packages still work fine in my tests.

I've attached a patch for a pu to the openchange package in jessie.

Thanks for taking over!

But openchangeproxy will still not be installable in jessie since
samba-libs has

Conflicts: openchangeproxy (<< 1:2.2-6)

Lowering this to (<< 1:2.2-5+deb8u1) would require another samba upload
to jessie (or piggybacking it on the next security upload).

Since noone has complained about this uninstallability so far in a
production environment, maybe the package is not in wide use ... and
dropping it might be another option.

I forgot about that. Since 1:2.2-6 was once in Debian, it would be
probably best to use 1:2.2-6~deb8u1 but that doesn't match what samba
used in the Breaks, so it will have to be 1:2.2-6+deb8u1, which should
be fine since 1:2.2-7 was the latest version in Debian stretch.
I'll change the version number and upload once I have an ack.

I think that isn't a useful use of samba maintainer/buildd time :)

Ack, though the version change I mention above should be fine though.
