• semantic versioning for UT

    With the new idea for changing up OTA process, I also want to propose new version system that makes sense.

    I propose to use Semantic Versioning
    https://semver.org/

    0_1539724648267_c4f00cf3-507c-4db6-bbb8-be949563f74f-image.png

    This way we could completely get rid of framework and only rely on the version to describe both version and api/abi compat. It would also give you a lot more info about the version you are on example that a major bump has a much bigger change then for example patch.

    MAJOR: bigger change that Breaks ABI/API
    MINOR: adds backwards-compatible bug fixes, changes and functionality (may break smaller library ABI in really special cases, but this should be notified about!)
    PATCH: adds backwards-compatible bug fixes.

    Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

    This would be how our different channels would look
    1.6.2-beta2 -> 1.6.2-rc1 -> 1.6.2
    beta -> rc -> stable

    This way you would know what version becomes what, example you know that 1.6.2-rc will become 1.6.2 stable.

    This fits great in with the "gotta go fast" proposal by dalton, here is an example how that would work

    1 week:

    • 1.5.6-devel0
    • 1.5.6-devel1
    • ----- / ----- Devel continues like this daily
    • Last weeks rc becomes stable: 1.5.5-rc1 -> 1.5.6
    • Last devel build of the week becomes rc: 1.5.6-devel6 -> 1.5.6-rc1

    2 week:

    • New devel version starts: 1.5.7-devel1
    • Last weeks rc becomes stable: 1.5.6-rc1 -> 1.5.7
    • Last devel build of the week becomes rc: 1.5.7-devel6 -> 1.5.7-rc1
    • This continues weekly.

    Then monthly we do a minor bump with more advances feathers.

    We could also do a mix between slow and fast, where we are releasing stable monthly:
    1 week:

    • 1.5.6-devel0
    • 1.5.6-devel1
    • ----- / ----- Devel continues like this daily
    • Last devel build of the week becomes rc: 1.5.6-devel6 -> 1.5.6-rc1

    2 week:

    • Devel continues daily
    • Last devel build of the week becomes rc: 1.5.6-devel12 -> 1.5.6-rc2
    • This continues weekly

    Then after the month is over last weeks rc becomes stable: 1.5.6-rc1 -> 1.5.7

    Examples:

    xenial stable: 1.6.2
    xenial rc: 1.6.2-rc0
    xenial rc: 1.6.2-rc1
    xenial devel: 1.6.2-devel1
    bionic devel: 2.6.2-devel1

    We would also make a clear build date in settings, this way we can know we are on the latest build.

  • RE: Fix technical debt

    Hi @domubpkm, I've forked this post to keep the original on topic.

    We are planning to use OTA-6 only to fix bugs rather than new features. "Fixing technical debt" is basically "paying attention to the code that's already here, rather than bringing in anything new".

  • Gotta release fast

    The current OTA cadence isn't working with our development tooling and workflow. Let's fix that.

    The problem(s)

    The release of OTA-5 was a bit rough.

    • The decision to release came too late and didn't appropriately echo through every team involved.
    • There wasn't enough time to appropriately review all release material and make it the best it could be
    • It wasn't well communicated that the release would be phased over 5 days -- it'll be in everyone's hands on Wednesday

    All seems like communication problems, right?

    The hindsight

    Knowing what we know now (even this early after the release), I think I can speak for the entire team here:

    • We allowed ourselves to be taken away by Target Date Syndrome. That is, while hitting your target date is important, great software is more important.
    • We should have delayed the release rather than pushing it exactly when it said on the GitHub milestone. Even with the Ubuntu release clouding the news for the next couple of weeks, another week of development (and another of hard testing) would have been preferred to a hard push out the door.
    • We should have made a new framework version. The OpenStore (starting today) is able to hold updates back from people who don't have a framework version. This would have solved the pain people are experiencing with the Notes app.

    But the release still had some good points:

    • It was on time according to the GitHub milestone (we had pushed the release back a week earlier in the cycle)
    • The new features are impressive. Our browser is faster and more secure than it's ever been. New users are hearing better sounds (thanks @malditobastardo!). Upgraders are being met with a guided setup. Our Korean users have a keyboard all their own.
      • That doesn't mean that OTA-5 is perfect. It has its bugs, and we'd appreciate if you report any you find.

    So what now?

    Some of the issues and hindsight I mentioned above are just lessons that we needed to learn sooner or later. Now that we've been bitten, we'll let the scar remind us to do right. ;)

    We have a couple of options that I'll present here that should help us improve the pre-, during-, and post-release process.

    Gotta release slower...

    Our first option, which we were previously leaning toward, is to release on an 8-week cadence (with the option to delay if needed). We'd split out every milestone (and associated Stable release) like this:

    • Week 1: Introspection
      • Watch for critical issues coming in as the release phases in, be ready to stop
      • Discussion of what went well, what didn't go well, and what is looking promising but could improve from our last cycle (also called "roses, thorns, and buds")
      • Accept bugs into the current milestone by what developers say they will take during the cycle
    • Weeks 2-6: development
      • Merge larger changes earlier in cycle
      • bug fixes and performance improvements
      • Whenever anything happens, write it down to prepare for release announcements
    • Week 7: Does it test okay?
      • Required "Release OKs" are entered based on each team's testing and completed work:
        • Core development (Either @mariogrip or myself)
        • App development (@bhdouglass for sure)
        • Quality Assurance head (@neothethird or another leader of the QA team)
      • If any "Release OK" is not received or is denied, the release moves back to development to mend the problem.
    • Week 8: It's done, prep for release!
      • Make release pre-announcements heard throughout all the halls of UBports. No one should be surprised that an OTA is coming, unless they're living under a rock and their ISP is buried under a mountain of rubble
      • Continue testing just in case
      • Prepare release blog posts
      • Inform press that a release is coming

    As always, devel ships nightly, rc (Release Candidate) ships every week, and stable ships upon completion of all of this.

    The reason this would be pinned to an 8-week cycle is simple... with our set of (highly skilled and totally appreciated, I must say) contributors, it isn't feasible to promise any less than this without being in a constant state of "crunch time." That isn't safe for contributors, paid or otherwise.

    As I type this, I find there is no reason that the week numbers must be hardcoded, though... at any point during the cycle where all major teams OK the release, it is ready to ship. When all these OKs occur, a full week is needed to complete the release.

    Possible benefits

    • Formalizes our current release method
    • Encourages involvement of community members (OK'ers need to get their team's blessing to put in their Release OK)

    Possible problems

    • Security fixes are getting to users of Stable only every 8+ weeks. That is widely regarded as unacceptable in today's climate.
    • Real emphasis on testing isn't applied until week 7. Ideally we'd be hitting testing hard on weeks 1-8, but we are humans after all...
      • RC also doesn't make much sense until week 7, unless you're a developer
    • Since many changes can happen in 6 weeks, we've found this can be scary for upgrading users
    • The "Release OK" process could be a cause for contention among teams and their leaders
      • I really don't expect this, but I've been proven wrong before

    Gotta release fast!!!

    I hear you say: Ah, so that's where the title came from...

    This is the polar opposite of "Gotta release slower". If you must wave the buzzword flag, this is closer to an "Agile" method. Instead of slowing down the cadence, we ensure that there is one release to the stable channel almost every week. The release of a stable image looks like this:

    • Devel images built nightly
    • On Thursday (example October 18th), the devel image from Tuesday (example October 16th) is promoted to RC (unless there is an issue on ubports/ubuntu-touch labeled critical-devel)
    • The following Thursday (example October 25th), the RC image is promoted to Stable (unless there is an issue labeled critical-rc). The image is phased in over a period of 4-5 days.

    At most, users of Stable will be 15 days behind the current devel (Please correct me if I'm wrong... I'm not always the best with date logic). I'm open to adjusting the dates slightly as needed.

    If we felt it important, we could have the QA team OK these releases too. Nothing severe, just a "type the version number, check the box if no one's phone is broke".

    Our milestone system would move to milestones for each major feature rather than each major release, followed by Epics on GitLab for the same purpose as we slowly transition over. As parts of features land, the milestone becomes more complete.

    I'm not 100% sure how we'd label releases at this point... @mariogrip insists on using semantic versioning based on the API stability of the development framework. I say that we should use the week number of the devel build that creates the stable build, so someone getting the build on Thursday, the 18th of October, 2018, would receive 2018-W41. You can discuss that over here.

    Possible benefits

    • We are never more than 15 days (again, correct me if I'm wrong) behind upstream Ubuntu security fixes on the Stable channel
    • There is always a clearly testable image (you get new shiny things faster on RC)
    • There is always a clear need for testing (if you're on RC, you're helping protect users on Stable)
    • People don't press the big red button
      • Without the "OK!" process, there is less chance for major disagreement harming users
      • Less chance for mistakes while releasing or phasing
    • Bugfixes get to users faster
    • Developers (who should be using devel, glare) are using software closer to our users. When we were nearing the end of the OTA-4 cycle, the Ubuntu Touch we were using was very different from what most people were using.

    Possible problems

    • We're asking users to update a lot
      • Not necessarily a bad thing. Most desktop distributions I've used default to notifying users of updates every week. LineageOS also checks once per week.
    • Faster releases mean less potential testing (bugs hit users faster)
    • Higher chance of SystemImage failure (since we update more)

    So... what now?

    Personally, I'm leaning toward releasing fast... I think that the best way to release as a community is to make the computers do it instead.

    Depending on the methodology we decide as a community (and how fast we do it!), OTA-6 may be released under either option. If we decide in fewer than 2 weeks, OTA-6 will definitely use whatever we decide. If OTA-6 is ready before we decide, it will be the last release before we move to the new method.

  • RE: Set partition sizes when flashing

    No, actually...

    The devices which Canonical shipped have Ubuntu Touch installed on their /system partition. It is generally unsafe to resize this partition because Android devices are weird... More akin to a doomsday than stepping on a Lego

    The others (the Nexus 5, Oneplus One, and Fairphone 2) are installed to an image file which resides on /data/.

  • RE: Set partition sizes when flashing

    The image file can be resized, and I'm considering ways to make ubports-qa do this in case the user would prefer to use apt and turn off system-image upgrades. Of course we wouldn't be able to help people if they broke things in this state, but we can give them just enough rope to shoot themselves in the foot...

    I don't have one in particular. We're using the parts from the 16.04 showcase. At the moment I think we've got a great roundup (including your submissions). Might you have your ringtones in .ogg format, maybe?

  • RE: Apps using Oxide

    @doniks Yes there will be a transition phase, we wont "just remove" oxide :) The phase time really depends if and how many apps it breaks, since we keep Ubuntu.Web we really hope the transition would be minimal.

    What i meant with 100% QtWebEngine is that every part that is "pre-installed" like browser, web container etc would be moved over, not that we would remove oxide.

    Ubuntu.Web will still exist and will not go anywhere, It will still be based on oxide until oxide is removed, once oxide is removed it will be moved over to QtWebEngine so it will continue to work (unless it uses oxide only apis)

    The oxide api will be removed at some point, when is still unsure. We would need to go over and see how many apps use this raw, and how many apps will break as an result of this. We will also try our best to create a compat layer to be able to make the transition without breaking apps (like webapps+)
