@timo can we go ahead and get tracks allocated for this?

In hindsight we likely should not have published to stable but oh well

[Touch-packages] [Bug 1663048] Re: libmirclient in snaps gets out of sync with archive

[Timo Jyrinki]

UAP would probably like to move to the new tracks, like 1/stable,
2/stable etc. At the Hague sprint it was recommended to use what we
currently use, ie have "content" field with ubuntu-app-platform1, where
that 1 could be bumped to 2.

Tracks add another piece to the puzzle, where the latest stable content:
ubuntu-app-platform1 providing snap could continue to be available in
1/stable track. However I'm not sure if everything would work out yet in
practice if we'd have 2/stable with ubuntu-app-platform2 and apps
defining to plug into that - could ubuntu-app-platform1, ubuntu-app-
platform2 and apps using either co-exist fully with snap pulling updates
correctly to everything.

For now, and the mirlibs case, we might not want to go to that though
yet, but it's good that features needed are appearing.

OK, I found a way to work around that with symlinks, so unity8-session
is now using mir-libs.

Though don't rush to upgrade; something (else?) broke, so edge isn't
rendering on screen.  I think it's a gsettings issue, digging into it.

>From my end, I don't know of blockers for the UAP-without-Mir upload.

However, I would like to just take this moment to note that I haven't
heard any talk of actually bumping the UAP interface number.  Which
means that by removing libraries, we're breaking our snap interface
contract -- one we've released into the stable channel.

Now that's fine, teething pains and all that.  And maybe we don't expect
anyone to seriously be using the Mir libraries from UAP.  (Though
someone might be...)

Has the UAP team considered what the Right Thing would look like here?
At least as a thought experiment for next time.  But maybe even if it's
easy, we can do it here too.

mir-libs is only 0.26.0, but xenial overlay has 0.26.1.  I can't fix
unity8-session to use mir-libs until that's updated.

[Touch-packages] [Bug 1663048] Re: libmirclient in snaps gets out of sync with archive

[Michael Terry]

Didier and I settled on a version of desktop-launch that tries to use
mir-libs first, falling back to ubuntu-app-platform (while the libs are
in there), and if not, then falling back to an internal copy of the
libraries.

That should help the transition and doesn't encode a requirement on mir-
libs inside of desktop-launch.  But should enable the use of them if the
snap chooses.

This has landed and now also sets LD_LIBRARY_PATH to point inside mir-
libs for your snap, if mir-libs is connected.

So go ahead and update your snaps.  All you need to do is define the
plug and create the $SNAP/mir-libs folder.  Everything else should be
done for you.

[Touch-packages] [Bug 1663048] Re: libmirclient in snaps gets out of sync with archive

[Didier Roche]

I still think that this proposal creates a real burden, ABI breakage to
developers. This isn't part of the desktop helper for sure as it doesn't
follow any of the snappy best practices.

To compare paradigms, libwayland has a versioned protocol which is part
of the GNOME and KDE runtime in flatpak. I don't see this concept being
different from us and make it more difficult to package desktop snap
running on Mir than desktop flatpacks running on wayland.

I guess if the Mir team doesn't want to work on some stability, maybe
get the Mir team to document how to do it, what they should depend on,
and adding their own env variable to every single snap in the store (as
this needs rebuilding them all already)?

[Touch-packages] [Bug 1663048] Re: libmirclient in snaps gets out of sync with archive

[Michael Terry]

Didier, I mostly agree with you, but you are missing the context and
meetings that led to this approach.  I'm just the messenger here, and
anyone please correct me if I mess something up.

- The Mir team is actively working on a stable ABI 1.0 release.  That's
coming in short term (but will involve an ABI change when it lands).

- The Mir team is so-far uninterested in providing a stable socket
protocol, certainly in the short or medium term.  (Preferring instead to
say the library is the interface.)  This isn't a very snappy approach,
granted.  But it's been the approach they've used in the archive for a
while.

- *IF* the Mir team says "using a content snap is the only supported
way", we really don't want to make that content snap be u-a-p.  Partly
because there are Mir clients that don't care about the rest of u-a-p
(GTK has a Mir backend for example).  And partly because all the issues
around LD_LIBRARY_PATH and library content snaps (which is sort of a
nightmare that just hasn't happened to bite us yet) make it advantageous
to strongly limit the scope of an always-required content snap.

- I agree in theory Mir is not different than those other system
libraries.  Except that those system libraries tend to have a more
stable library and protocol interface policies.  Policies that mean the
interface can survive the lifetime of a Core series (which is all that
we care about, right?).  But Mir is not able to make such promises yet.

FWIW, the UAP branch for removing mir libs is available and linked now.
Since we agreed not to publish anything new to even edge for now (not to
mention beta or candidate), I'm not merging it yet or uploading anything
to the store.

[Touch-packages] [Bug 1663048] Re: libmirclient in snaps gets out of sync with archive

[Didier Roche]

I'm not really found of this decision from a pure developer experience 
perspective.
What would make Mir special compared to other system libraries, like 
libsystemd, pulseaudio, evolution-data-server, your email service libs, and so 
on and so on?

Sure, we can separate all of them, but we are back in the deb world, which is 
exactly what we want to avoid with snap. Also, changing all existing snaps for 
that change really shows something isn't coorrect.
It will mean that every applications that depends on mir-libs needs to declare 
an additional plug, create an empty directory and so on…

I guess a better solution to pave the way forward is either:
- get a version and stable ABI/API between the libs and the server (or this 
won't work on the long term anyway).
- get that transparently transition for applications. Meaning, the content 
ubuntu-app-platform interfaces still ship the Mir functionality. However, this 
could be done either directly or via another content interface snap. It may 
needs some upstream development.

Please discuss those changes on the snapcraft mailing list to not only
base on my opinion.
