Re: Let's Discuss Interim Releases (and a Rolling Release)

To succeed at this we will need both velocity and agility. Therefore, I am starting a discussion about dropping non-LTS releases and move to a rolling release plus LTS releases right now. = Role of the LTS Releases = Many users prefer their OS does not change very often. We have a great system in place for these users. Every 2 years Ubuntu release an LTS and users can ride that LTS for the whole support period. Since the LTS comes out every 2 years, they can set a 2 year cadence of updates if they want to stay "up to date" with LTS releases. I think this 2 year cadence works out very well for these users. So, this proposal maintains those LTS releases as anchors for those users. = Role of the Interim Releases = But what about the 3 releases we do every six months in between (what I call the "interim releases")? Who are they for? Why do we invest so much in supporting multiple interim releases at a time? I think the value of the interim releases has run its course: * Customers (people who pay Canonical and others to support Ubuntu) like OEMs and Enterprises have all adopted an LTS to LTS cadence. * Many community members recommend only LTS releases to new users because of its longevity and stability, but the interim releases cause confusion about what is the “right” version for someone to install. * As Scott James Remnant pointed out some time ago, the six month cadence causes features to be either rushed, or to have to wait for six months to be released (along with other problems). (http://netsplit.com/2011/09/08/new-ubuntu-release-process/) * Due to Daily Quality efforts, the development release is now usable every day, so enthusiasts and community members don’t have to wait for a stable release to get the latest software and can participate more fully in the development of Ubuntu * Supporting interim releases is a costly distraction from future development, a cost in both time and attention. = Ubuntu NG = In the meantime, with Ubuntu Touch, the Phone, the Tablet, and convergence of these device experiences with the Desktop, we are in the process of inventing what is essentially a next generation Ubuntu. There will be lots of new code written and code integrated from new sources to accomplish this. The 13.04 Desktop would not have any of this new code, and therefore will be "old" before it is even released. Therefore, I think we should keep LTS releases, but starting now, stop doing interim releases and start a rolling release. More clearly, I think we should: * Stop making interim releases. * Keep doing daily quality and keep improving our daily quality. * Take a monthly snapshot of the development release, which we support only until the next snapshot That means users could choose: * The LTS release * The rolling release updated daily or as frequently as desired * The rolling release updated at least monthly = Benefits of Moving to a Rolling Release = A rolling release instead of interim releases will benefit users, community members, and developers. == For Users == Users who prefer the LTS releases will be unaffected by this change, at least directly. For users who prefer more up to date software, the rolling release will truly provide the latest and greatest software that they are looking for, but without the 6 month wait for a new release. Developers won’t be under pressure to rush a feature in before the release deadline, so users will be receiving more complete software when they do get updates. == For Community == The community will benefit from the simplified model. They will be able to recommend either the LTS or the rolling release, and the users of each will be clear. People who need to provide support may find their lives dramatically simplified, because on any one day, there will essentially be 2 releases with clearly differentiated user bases instead of their user base being distributed across a minimum of 3 supported releases. For example, on any one day, an ISV typically would only have to worry about the LTS releases and the current rolling release, instead of 11.10, 12.04, 12.10 and the current development releases, Raring. == For Core/MOTU Developers == For the people who are actually making Ubuntu (the people on this thread I hope) there are some clear wins as well. 1.

More time and attention to focus on what we are building instead of what we had built. 2. Features land when they are ready, not earlier or later. 3.

GCC 4.7, STL and binary compatibility of objects built with different language standards
Hi, I've just finished debugging a Unity crash which occurs when we try a test rebuild of Unity and Nux with GCC4.7 in quantal. Although the original issue was caused by mixing 2 C++ ABI's (because libsigc hasn't been rebuilt yet in quantal), it was no better even after rebuilding libsigc with the quantal toolchain. What is happening is, in GCC4.7, std::_List_base::_List_impl has a data member which only exists for compilation units that are built with -std=c++0x (_M_size). This means that the STL ABI is dependent on the language standard. This obviously causes issues when a process loads libraries that are built with different language standards and which pass std::list's across public API's In the Unity case, both Unity and Nux are built with -std=c++0x, but they use libsigc which is not built with it and which exposes STL objects in its public API. Rebuilding libsigc locally with -std=c++0x is sufficient to make Unity work properly. However, uploading this will probably break anything else in the archive using libsigc which isn't built with -std=c++0x, so I'm not sure of the best way to proceed. In addition to welcoming other people's opinions, I also want to make sure that other people are careful here don't fall in to the same trap :) Regards Chris -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel

We actually use Breakpad for Firefox and Thunderbird in Ubuntu already, rather than Apport - primarily so upstream have some visibility of crashes from Ubuntu users.

Re: Removing XULRunner from oneiric - call for help
Hi, I've already spent way too much on time on this and I really need to be doing other things, so unless someone steps up now for a particular application that they care about, the remaining pacakges depending on xulrunner will be dropped from the archive by alpha 2. This includes: - xiphos - needs either porting to Webkit (probably a lot of work, but not sure yet) or switched to using is gtkhtml backend (easy, but gtkhtml sucks). - dehydra - already using Spidermonkey, but needs switching to use the proper lib. Probably just minor build-system changes. - mongodb - same as dehydra. - edbrowse - needs porting to Spidermonkey 1.8.5. Based on experience of doing this already for couchdb, gxine and mongodb, this is probably going to be a lot of work for the unfortunate victim who ends up doing this. The list of remaining work can be found at https://blueprints.launchpad.net/ubuntu/+spec/desktop-o-mozilla-rapid-release-maintenance There are still other outstanding items not mentioned here, either because people really shouldn't bother with them, they have someone assigned or I still plan to look at them (eg, vlc, fennec and eclipse). If I've not heard anything by the end of the week, I will assume that nobody cares about the remaining packages and will start filing removal requests for them.

Removing XULRunner from oneiric - call for help
Hi, At UDS we decided that we are no longer going to maintain XULRunner in the Ubuntu archive from Oneiric onwards (although, this process already started at the end of Natty when we did some last minute work to demote it to universe). The reason for this is that the new rapid release cadence for Firefox [1] makes XULRunner difficult to support for the entire life of an Ubuntu release (up to 3 years for a LTS). The new process doesn't really affect us that much for Firefox - we will still get security updates at a similar frequency as before, and the changes between these updates will be mostly incremental. The main differences are that regular security updates (e.g., the upcoming 4.0.1 => 5.0 update) will bring incremental changes to strings and API, whereas these previously only happened during major version upgrades (such as the recent 3.6 => 4.0 upgrade). There will also only be one supported stable branch in the future, as opposed to the multiple supported stable branches that we've been used to in the past. The development cycle is fairly similar to that of Chrome/Chromium. The reason this makes XULRunner difficult to support is that regular security updates will be exposed to API changes. Although these will be incremental, it means that the security team would have to spend a lot of time every 6 weeks or so transitioning and testing applications to make sure that they continue working. I know this is the case as I maintain a binary extension for Firefox which I've already had to make changes in, to ensure that it continues working on the latest nightly builds of Firefox from mozilla-central. The alternative to this is to just backport major security fixes to the version of XULRunner we ship at release time, but we already know from past experience that this is a lot of work too, and I don't think anybody is going to volunteer to do that. I really don't think we have enough bandwidth to pursue either of these options with an acceptable level of quality. In addition to this, Mozilla have removed the GtkMozEmbed embedding API [2], which is still being used by some applications in the archive (chmsee + anything depending on python-gtkmozembed). The work to remove XULRunner is being tracked in the desktop-o-mozilla-rapid-release-maintenance blueprint [3]. When I started creating work items I realized that we still have quite a lot of applications in the archive that are using it. Over the next few days I'm going to be reviewing these dependencies to work out what we should do with each package. Where applications do have a hard dependency on XULRunner, I will try to spend time removing that dependency, e.g., by porting those to an alternative API (such as Webkit). This is where I would appreciate help from anyone who has a particular interest in any of the affected applications listed on the blueprint. Obviously, it would be a shame to lose applications such as chmsee (I use that, and this is one application which I think is definitely worth keeping), but I'm not going to spend significant amounts of time working on applications which aren't that popular or are not very well maintained. So, the current plan of action is: - Browser plugins that are currently depending on xulrunner-dev just to include the NPAPI headers can depend on firefox-dev for those instead (eg, packagekit). The alternative is to include a local copy of the headers instead (eg, Totem does that). - Browser plugins that are actually using Mozilla interfaces will need to be modified to not do that (or they will be removed from the archive). An example is gecko-mediaplayer which uses nsIPrefService to modify preferences which change the UA string at run-time. This is an easy fix, as this doesn't even work in Firefox 4 any more (the preferences it touches were removed). - Anything using GtkMozEmbed is doomed anyway - they need porting to another embedding API regardless of what our plans are in Ubuntu. This includes chmsee, screenlets and lernid. - Anything just using Spidermonkey can use libmozjs now, as we have a proper library for this. These should be fairly trivial to fix if they are already using xulrunner-2.0, as they will probably just require some build system tweaks. If they are still using xulrunner-1.9.2, then there may be a significant amount of pain involved, as jsapi changed quite a bit between the 2 versions. - Anything that is using XULRunner as a general purpose toolkit (as opposed to just embedding) is going to be difficult to support, and we are probably just going to remove those from the archive without spending any time on them. This includes instantbird. If anyone has any questions or wants to help out, then please feel free to grab me on IRC.
