Merge lp:~mterry/deja-dup/no-python2 into lp:deja-dup/34

[Michael Terry]

Use packagekit to install duplicity on the fly if needed, removing any dependency on python2 by deja-dup directly.

Add missing function declaration

[Didier Roche-Tolomelli (didrocks)]

Hey Michael! Some review before some general thoughts :)

Code-wise:
I didn't spot anything horrible here at least. Everything should be working fine. It builds as well and seems to work on my existing install (even removing duplicity).

Tests:
I couldn't get the tests passing on sbuild (wily or xenial). The failing tests are here:
60% tests passed, 37 tests failed out of 93

Total Test time (real) = 82.80 sec

The following tests FAILED:

In general:
I feel quite uncomfortable about this change claiming "dropping python support" by installing duplicity on the fly (and so, dropping it as a recommend).
First, I guess that duplicity will need to go to universe so that it's not pulled when we build the iso. Does it means that duplicity isn't supported officially anymore?
Secondly (and that's my main point), from the code and my understanding, duplicity is the only supported backend, right? Meaning, deja-dup is useless without it? That means that we will ship useless software by default and anyone who wants to do backups will then have to install duplicity, assuming it's supported by default as it's coming from an application which is supported. I feel this is just ticking up a box "no python2 on the install" where it's lying to ourself: most of users will still have python2 installed if we apply the same semantic to multiple projects. That's the reason I don't feel that this change is fully right.

Of course, if déjà-dup works well without duplicity for other form of backups, I withdraw that comment :)

review: Needs Fixing

[Michael Terry (mterry)]

@didier, thanks for looking at this!

re: tests, guh! LP doesn't see the failures and I don't see the failures. I don't know what you and Ken have going on. (timezones? locale? -- I will look for something along those lines that could fail the tests).

Regarding your broader point about this approach:

- Yes, duplicity is the only supported backend.

- We don't plan to demote duplicity, we'll leave it in main. It will still be supported. This is just a step on the path to python3-only-in-main. Eventually we will have to port it. (to keep it off the image, we'll move it to a Suggests for deja-dup -- and let the other derivatives know that they need to seed duplicity if they want to keep shipping it on their own images)

- Landscape is a precedent for shipping a hook for functionality that then installs the rest.

- I wasn't going to be able to commit the time necessary to port duplicity to python3 for 16.04. So it's either this or dropping deja-dup unless a volunteer does it -- patches welcome... ;) And I think keeping a user interaction point to nudge people towards backups is better than dropping it from the image.

- We aren't lying to ourselves so much as iterating and reducing the scope of python2 installs. It's still in main. We're working on that over time. And maybe if duplicity remains python2, we'll eventually drop deja-dup. But for 16.04, we're shooting for the base install not having python2 anymore (which is not nothing -- CVEs & bugs affecting python2 will no longer affect every single Ubuntu user; only some of them).

- Note that this MP itself doesn't actually change anything in Ubuntu. This debian/ packaging is just for the upstream PPA (and doesn't even drop duplicity to a Suggests). Your broader concerns are really about the planned followup MP for the deja-dup packaging that updates to this code and then will drop duplicity to a Suggests for Ubuntu. But talking about them here is fine and good. But maybe shouldn't be a blocker for *this* change.

[Didier Roche-Tolomelli (didrocks)]

I'm happy with your answers, even if I still think that brings to "we ditched python2 from the default installed, woooww" at the price of lost functionality that will never be properly fixed. This as well shift the focus on fixing the real issue bringing less pressure to it (and so, will probably never be done) but as you told, it's more a personal opinion than something on this MP itself which is more for upstream déjà-dup.

On the tests, using default sbuild, it shouldn't have any timezone/locale specific issue. I'm building on amd64. Can you reproduce the issue this way?
$ bzr bd -S; cd ..
$ sudo sbuild-launchpad-chroot create -n xenial -s xenial -a amd64
$ sbuild --dist=xenial --arch=amd64 -c xenial deja-dup_0.dsc

(I'm building without -proposed, I can try with it if that's the issue? Note that I tried as well with a wily chroot)

[Michael Terry (mterry)]

@didrocks, fixed the build in sbuild. So I think this branch should be good? (if tests pass for you)

As discussed on IRC, I think you are also reluctantly on board with landing this change + duplicity-as-Suggests in Ubuntu?

[Didier Roche-Tolomelli (didrocks)]

I did another run on xenial or wily sbuild and still got one error that I can reproduce reliably:
      Start 66: read-error.test
66/93 Test #66: read-error.test ..........................***Exception: Other 6.90 sec

/sbuild-nonexistent/2, got (null)

      Start 67: disk-full.test

All the other tests are fixed, nice work! Do not hesitate to ask if you want more debug info if you can't reproduce this one.

"Reluctant" is the word ;) for the reasons we discussed on IRC (shifting the focus, claiming that we removed python3 from the CD which isn't really the truth if you want to use all features that we ship by default), but I understand the constraints and anyway, from a pure upstream perspective, the change is fine.

Guh, stupid HOME tests. I ctrl+c'd the tests once I saw they were passing. Wanted to save myself a whole minute, but I would have seen this failure if I waited. :)

Fixed now. They all pass for me in sbuild.

[Didier Roche-Tolomelli (didrocks)]

Yeah, it's passing now, +1 then :)
