Lunar: Reproducible builds: week 22 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Packages fixed The following 22 packages became reproducible due to changes in their build dependencies: breathe, cdi-api, geronimo-jpa-2.0-spec, geronimo-validation-1.0-spec, gradle-propdeps-plugin, jansi, javaparser, libjsr311-api-java, mac-widgets, mockito, mojarra, pastescript, plexus-utils2, powerline, python-psutil, python-sfml, python-tldap, pythondialog, tox, trident, truffle, zookeeper. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: diffoscope development The changes to make diffoscope run under Python 3, along with many small fixes, entered the archive with version 35 on September 21th. Another release was made the very next day fixed two encoding-related issues discovered when running diffoscope on more Debian packages. strip-nondeterminism development Version 0.12.0 now preserves file permissions on modified zip files and dh_strip_nondeterminism has been made compatible with older debhelper. disorderfs development Version 0.3.0 implemented a multi-user mode that was required to build Debian packages using disorderfs. It also added command line options to control the ordering of files in directory (either shuffled or reversed) and another to do arbitrary changes to the reported space used by files on disk. A couple days later, version 0.4.0 was released to support locks, flush, fsync, fsyncdir, read_buf, and write_buf. Almost all known issues have now been fixed. reproducible.debian.net disorderfs is now used during the second build. This makes file ordering issue very easy to identify as such. (h01ger) Work has been done on making the distributed build setup more reliable. (h01ger) Documentation update Matt Kraii fixed the example on how to fix issues related to dates in Sphinx. Recent Sphinx versions should also be compatible with SOURCE_DATE_EPOCH. Package reviews 53 reviews have been removed, 85 added and 13 updated this week. 46 packages failing to build from source has been identified by Chris Lamb, Chris West, and Niko Tyni. Chris Lamb was the lucky reporter of bug #800000 on vdr-plugin-prefermenu. Issues related to disorderfs are being tracked with a new issue.

Bdale Garbee: FreedomBox in Banja Luka

FreedomBox activities at Debconf11 I spent the last two weeks of July 2011 in Banja Luka. The occasion was the annual Debian developer's conference, Debconf11 and preceding work week known as Debcamp. This was my tenth successive year attending Debconf, and I had a very productive and pleasant time! The facilities were good, the local team was friendly, enthusiastic, and very helpful, and in addition to giving three talks and hosting a couple panel discussions, I managed to put a burst of energy into work on FreedomBox. Several other developers working on FreedomBox were also present, and a good number of Sheeva and Dream plugs were evident in the hacklabs sporting new FreedomBox stickers. Working together in the same place for several days, we made good progress on several projects, and also had some great discussions about what we want to do going forward. image building tools For some time, I've been working towards a light-weight tool set to build FreedomBox software images. Shortly before Debconf started, I chose the name 'freedom-maker' for this tool and shared a link to a readable copy of my git repository with other developers I expected to work with in Banja Luka. With input from Bert Agaz and Jonas Smedegaard during Debcamp, freedom-maker went from almost useful to actually useful. It still deserves work to be more useful to others, but I have now pushed a copy of the git repository to git.debian.org so that we can take advantage of the tools supported there to enable others to more easily contribute to the code. Very soon, Bert plans to add support to freedom-maker for using Lars Wirzenius' vmdebootstrap to build x86 images suitable for testing in a virtualized environment. At the same time, we plan to refactor the existing code slightly to enable lists of desired packages for the various image flavors we expect to produce independently of the configuration for each specific image building tool. Jonas continued in parallel to work on his alternate packaging toolset boxer. It offers some potentially interesting features for the future, and we may eventually merge some or all of it into freedom-maker, but for now it remains a separate utility. uAP user space tools Several weeks ago, we received from Marvell the source code to two user space programs that are necessary for configuring and monitoring the binary firmware provided for the uAP wireless chip used in the DreamPlug. Early during my stay in Banja Luka, I packaged these for Debian as uaputl and uapevent, and I am pleased to note that they were quickly accepted into the archive and are now present in Debian mirrors. u-boot Another bit of code received very shortly before Debconf started was the source for the version of u-boot shipped by Globalscale in the DreamPlug units we're working with. During Debcamp, Clint Adams passed a copy of this source to Jason Cooper, who was already trying to add support for the DreamPlug to upstream u-boot, but had stalled due to a lack of information. Jason has now merged his own work with the sources we got from the manufacturer, and is making good progress towards merging DreamPlug support into upstream u-boot. Once that happens, we should be able to flash our Sheeva and Dream plug devices with a u-boot image built from the source in the Debian u-boot package, in the process enabling things that matter to us like the ability to boot from an ext2 partition, and hopefully the ability to execute command scripts from that partition instead of having to hard-code kernel filenames in flash. This will allow us to support the ongoing effort in Debian to move away from the need for kernel symlinks. DreamPlug kernels With respect to kernels, another work stream at Debconf primarily involving H ctor Or n and Nick Bane was to analyze the current state of the patches from Marvell and Globalscale used to support the DreamPlug against both upstream and current Debian kernel sources. To my surprise and our collective pleasure, the remaining patch set required against current upstream kernels is much smaller than we previously believed! There are still several patches critical to us that are not merged upstream, but the work remaining to be able to build images for our devices from mainline and Debian kernel source trees now seems like something we might be able to complete before Debian's next stable release. One of our discoveries during the u-boot and kernel work during Debconf was that Globalscale did not obtain a new machine id for the DreamPlug, but instead re-used the one for the GuruPlug series, despite there being some differences in the hardware that require at least one additional driver. After much discussion, we plan to continue using the existing machine id instead of requesting another, particularly because the ARM kernel community has apparently stopped issuing new ids for the moment. We will add a new kernel config option for the DreamPlug, however, and are likely to build distinct Sheeva and Dream kernel packages that do not require initrd for use in FreedomBox images, even if doing so is not strictly necessary. This will allow us to optimize both the in-memory footprint and boot times for our devices. software configuration Another area of investigation in Banja Luka was technology for package configuration. Mirsal Ennaime performed various tests using debconf and Config::Model, with some results reflected in this commit relating to configuring the bitcoind daemon in the bitcoin package for Debian. identity and trust management While we did not actually do any FreedomBox specific work on the trust management layer we know is necessary, after several rounds of conversation, I am now more convinced than ever that the right path forward is to base our trust relationships on OpenPGP keys using GnuPG and Monkeysphere as starting software elements. Our thinking to date is captured on an Identity Management page in the wiki. communication services Another thing that became fairly clear to me during discussions at Debconf is that in the near term, planning to build communication services around XMPP is the approach most likely to give good results. Investigating the software choices available to build an interesting XMPP infrastructure is now a high priority for me. Jonas has done some work towards configuring and integrating ejabberd or Prosody, I've started studying yate as a possible call manager and VoIP server choice with XMPP/jingle support, and we await with great interest a release from the Buddycloud developers to evaluate as a possible basis for deploying social network services. Some of these software choices will lead us to use Apache as our web services base technology because of the need for features that only it supports well among daemons that are Free Software. Jonas completed packaging GNU Sip Witch for Debian, and it is now available in the mirror network. Tzafrir Cohen and Jonas did some initial testing on its use. documentation A number of new wiki pages were written (or at least started) in order to sum up ideas, design various aspects of FreedomBox, and reflect discussions that happened during DebConf11. A lot of work is needed to complete these pages though, as well as others to capture more of the current state of the project. press coverage Finally, while in Banja Luka I got some great press coverage for FreedomBox! On Sunday the 24th, I was interviewed by the main television network serving the Republika Srpska. This led to a couple of minutes of coverage near the top of the national news program that night, immediately following the lead story about the President and several ministers appearing at Debian Day that morning to help open the conference. This interview was later re-used in another TV program that summarized Debconf11. On the morning of Thursday the 28th, I was part of a small group that spent more than an hour meeting with the Minister of Science and Technology in his office, and the relationship between Debian and our work on FreedomBox was one of the items of discussion in that meeting and the associated press conference. I'm told this resulted in more press coverage, but if true I have not seen it yet. summary On Friday afternoon the 29th, I gave a talk in the main Debconf program containing a FreedomBox Progress Report . In it, I talked about the structure of the FreedomBox Foundation, progress the foundation has made, and the work that was still then underway in Banja Luka. It was streamed live over the internet, and replays are available online. The reaction from Debian developers present was very positive, which was good to learn since by that time my energy level was quite low after the nearly two weeks of intense technical and social interaction that is Debconf! All in all, we got lots of work done on FreedomBox in Banja Luka, enough that I think at least the next few steps along the road towards an eventual "1.0" release of a reference implementation are now much clearer than they were two weeks ago!

Philipp Kern: Stable Point Release: Etch 4.0r4 (aka etchnhalf)

Another point release for Etch has been done; now it's the time for the CD team to roll out new images after the next mirror pulse. The official announcements (prepared by Alexander Reichle-Schmehl, thanks!) will follow shortly afterwards. FTP master of the day was Joerg Jaspert, who did his first point release since Woody, as he told us on IRC. We appreciate your work and you spending your time that shortly before going to Argentina. This point release includes the etchnhalf update introducing a new kernel image (based on 2.6.24) and some driver updates. Additionally the infamous openssl hole will be fixed for good, even for new installs. Again I want to present you a list of people who contributed to this release. It cannot be complete as I got the information out of the Changed-by fields of the uploads. From the Release Team we had dann frazier (who drove the important kernel part of etchnhalf), Luk Claes, Neil McGovern, Andreas Barth, Martin Zobel-Helas and me working on it. ;-)
