Contributing Writer: Adam Batkin

[edit] General

Michael DeHaan discussed[1] various Linux system configuration applets and some ideas how to unify/integrate them. On an unrelated note, he also wrote[2] about HTML Slidey[3]: Slide Shows in XHTML.

Gary Benson announced[4] that Zero has passed the Java SE 6 TCK, which means that OpenJDK in Fedora 10 for 32 and 64 bit PowerPC-based systems are now pretty much guaranteed to run anything you can throw at them.

Daniel Walsh explained[5],[6] some SELinux history, voodoo and how to rebuild bits of the policy RPMs.

Jeremy Katz reviewed[7] the book Don't Make Me Think by Steve Krug and how that applies to web usability.

Red Hat Magazine[8] spotlighted[9] Func, which "makes it easy to write commands across large numbers of machines remotely and securely".

Ankur Sinha wrote[10] an article about the history of Fedora and its four core values.

Jef Spaleta wondered[11] how popular Git was, and found some interesting statistics from GitHub. He also discovered that apparently some[12] Canonical developers (the kernel folks) do used Git instead of Bzr.

Ryan Lerch described[13] how to "Create a Lightbulb Icon that follows the tango! guidelines".

Jack Aboutboul wrote[14] about what can be done to rejuvinate Fedora Marketing.

Lennart Poettering explained[15] how to "tag" audio streams so that Pulse Audio can automatically manage sound policy ("For example, starting in 0.9.15, we will automatically pause your media player while a phone call is going on").

Seth Vidal described[16] how to adapt to the change to SHA256 checksums in yum/createrepo on EL5.

[edit] QualityAssurance

In this section, we cover the activities of the QA team[1].

Contributing Writer: Adam Williamson

[edit] Test Days

This week's regular test day[1] was on 20 Second Startup[2]. Harald Hoyer was the developer present, and there was a great turnout of 20 people contributing test results. Further results are still welcome from anyone - a full set of instructions for running tests is available on the Wiki page. As a result of the testing, Harald has made several modifications already that will help to optimize boot times for Fedora 11.

Next week's test day[3] will be on the Crash Catcher[4] feature planned for Fedora 11, which aims to make it easy for non-power uses to file useful reports when an application crashes. It will be held on Thursday (2009-02-26) in the #fedora-qa channel on Freenode IRC. Please drop by if you would like to help test this important new feature for Fedora 11 - no special equipment or expertise required!

[edit] Weekly meetings

The QA group weekly meeting[1] was held on 2009-02-18. The full log is available[2]. Will Woods gave a status report on the progress of the autoqa[3] project, which is working on creating automated test scripts to run whenever certain events happen. The group agreed to create an autoqa component in the fedora-qa trac instance, and create a new mailing list for autoqa reports to be sent to (this will not be a discussion list). Adam Williamson, James Laska and Jóhann Guðmundsson then initiated a discussion about creating a short-term solution for more organized reporting and collection of test results. Follow up a mailing list discussion, a system created by the Laptop.org[4] project, implemented as a Mediawiki plugin, was discussed. The group agreed that it seemed suited to the purpose, and James will propose it to the Infrastructure group, to see if they approve of the system, and whether they would prefer it to be added to the main Wiki or a special-purpose Wiki instance created just for this use. Finally, the group discussed the (then) upcoming test day, and agreed preparations were well in hand.

The Bugzappers group weekly meeting[5] was held on 2009-02-17. The full log is available[6]. A broad initial goal for the Bugzappers project was agreed: to stabilize the number of bugs in NEW (i.e. un-triaged) status on the components previously agreed to be the most significant. Brennan Ashton's metric reporting tool will be used to track this. Brennan demonstrated the current state of his tool on a small set of test data, to general approval. The group voted on Adam Williamson's proposal to have a stock signature appended to comments by members of the Bugzappers team in Bugzilla, both to identify the Bugzappers and to increase the visibility of the project. This was approved, and Matej Cepl will implement it using Greasemonkey, adding it to the Greasemonkey script already used by most Bugzappers.

The next QA weekly meeting will be held on 2009-02-25 at 1600 UTC in #fedora-qa, and the next Bugzappers weekly meeting on 2009-02-24 at 1700 UTC in #fedora-bugzappers.

[edit] Wiki re-organization

Adam Williamson announced[1] that the first phase of the Wiki re-organization project was complete, with the new front page and 'how to join in' page for the QA Wiki space put into place.

  1. http://www.redhat.com/archives/fedora-test-list/2009-February/msg00710.html

[edit] Reporting bugs to Bugzilla

Christopher Beland encouraged[1] testers to report bugs to Bugzilla as well as sending a mail about them to the test-list mailing list, and told the group that he had added some text to this effect to the QA group front page on the Wiki. Adam Williamson suggested[2] that the text might be better placed on the Wiki page about how properly to report bugs, rather than the QA group front page.

[edit] Semantic - test reporting plugin for Mediawiki

James Laska sent in a report[1] on Semantic, the Laptop.org project's Mediawiki extension for managing test reports.

  1. http://www.redhat.com/archives/fedora-test-list/2009-February/msg00756.html

[edit] Encouraging Rawhide testing

Mark McLoughlin made some suggestions[1] about how to improve the ongoing quality and consistency of Rawhide, in order to make it possible for more people to test it. He suggested that a definition should be made of what should be expected to work in Rawhide all the time - e.g. basic installation, booting, network and a few core applications - and a RawhideBlocker tracker bug be created on Bugzilla to track bugs in Rawhide which breaks any of these functions, with the intention that those bugs be addressed as a matter of high priority.

[edit] Developments

In this section the people, personalities and debates on the @fedora-devel mailing list are summarized.

Contributing Writer: Oisin Feeley

[edit] Fedora 11 Mass Rebuild

Some complications resulting from the inconsistent application of Fedora Packaging Guidelines were manifested when the mass rebuild discussed last week(FWN#163[1]) gained[2] a more concrete shape. Jesse Keating posted[3] a request that all maintainers would read the wiki page describing what needs to be done, especially the Maintainer Actions section.

The rebuild should kick-off this Monday (2009-02-23). The wiki page describes the relatively narrow timeframe in which maintainers can attempt their own rebuilds and the way in which they can avoid the auto-rebuild.

Concern was expressed by Tom Lane that the rebuilds were non-ordered. Jesse responded[4] that ordered builds were "[...] generally only are necessary when bumping sonames or otherwise bootstrapping items. Given that neither of those apply for this rebuild, effort spent trying to order and chain builds would be effort wasted." Ralf Corsepius challenged[5] this with the observation that pkgconfig BuildRequires are added automatically. Ralf suggested[6] the problem could be solved by "[...] checking which packages in current rawhide contain *.pc's but do not Provide nor Require pkgconfig(foo) and to rebuild them (in manually presorted order) in advance to the mass rebuild."

Jon Masters appreciated[7] Jesse's work and worried that the rebuild might leave some statically built binaries using i386 instead of the promised i586 (see FWN#162[8]). Subsequent rebuilds were suggested as a means to work around the problem but Jesse preferred to identify specific problems and stated[9]: "I think the most I'd be willing to do would be a second build pass across the static packages. IMHO everything else should be left up to testing discovery and fixing the assumptions rather than hiding them."

Another approach was suggested by Conrad Meyer based on using BuildRequires: *-static. When Ralf replied that this would not work because many packagers who had not used static subpackages Conrad pointed[10] to the guidelines. Nicolas Mailhot ruefully responded[11] that his experience with the fonts guidelines suggested that enforcement was necessary. Later discussion with Jakub Jelínek about the presence of libc.a in glibc-devel suggested[12] that it will not be simple to apply this particular guideline to glibc without gcc -static ceasing to behave as expected.

[edit] Virtual Provides for Login Managers

Following problems reported[1] with booting to runlevel 5 by default with the slim login-manager Chris Lumens suggested[2] that "[...] all packages containing a login manager include a special Provides: that we can query on." This would allow anaconda to determine whether a login-manager is installed without the difficulties of curating a list.

Patrice Dumas, and others, provided[3] a good deal of feedback which seems to have led to a consensus that Provides: service(graphical-login) will be added to all packages which provide a login manager.

An interesting sub-thread developed in which Colin Walters argued[4] that adding display managers (other than gdm and kdm should be strongly discouraged. This was met[5] with a good deal of disagreement from Tom Callaway and Seth Vidal.

Colin explained[6] that the ramifications of changing such an integral part of the OS were complex and that while anyone should be free to add such software it should also be "[...] within the rights of the people working on the desktop to close any bugs filed by people using something else WONTFIX." Jesse Keating and Seth Vidal seemed[7] to agree that it should be possible for the Fedora Project do define specs to which login managers should conform.

The thread blossomed into several discussions. One focused on the technical challenges occasioned[8] by the interaction of GDM, PAM, gnome-keyring, NetworkManager and ConsoleKit. Another saw[9] Toshio Kuratomi and Colin debating the strategic merits of making it more or less easy for interested parties to add their software to the Fedora Project ecosystem.

[edit] Reducing the Number of (Dis)Charge Cycles for Laptop Batteries

A certain amount of excitement resulted when Brad Longo asked[1]: "[...] if Fedora's power management tool has something built in so that when the battery reaches full charge, it will then discharge to lets say around 95% before beginning to charge again." The excitement arose from Brad's premise that "[...] leaving your laptop plugged in and charging with a full battery charge is harmful for the battery."

Several responses rejected[2] the premise and pointed out that smart chargers implement trickle-mode charging. Matthew Garrett replied[3] with some specific information about how laptop battery charging happens at a firmware-controlled threshold level. Matthew speculated that Brad wanted "[...] presumably an interface to modify that threshold. This is device specific. The tp_smapi driver (which is not in the kernel for exceedingly dull reasons) allows this to be configured on Thinkpads. I don't believe that we know how to on any other systems." Hans Ulrich Niedermann had[4] an out-of-kernel module for tm_smapi which was configurable via /etc/sysconfig.

Matthew Saltzman reported[5] some experiences with Windows setting the charge-threshold to 85% which is supposed to lengthen the battery life. Callum Lerwick referenced[6] a Wikipedia article which claimes that the "[...] optimal storage charge for a Li-Ion is %40. Also, heat causes Li-Ion batteries to degenerate much faster, so if you're really worried about preserving your battery, don't leave it in the laptop while it's running. Yet another argument for less power usage. Less power, less heat, longer battery service life. Fewer toxic batteries going in to the land fill if you like that angle."

[edit] config.guess Reporting Incorrect Configuration Name ?

Panu Matilainen asked[1] if it was a problem that the config.guess script from autotools no longer reported "redhat" as the manufacturer part of the configuration triplet. Panu referenced the documentation which suggests that "[...] the manufacturer part of the configuration name is the manufacturer of the CPU, not `OS vendor' so the former `redhat' was always incorrect. I don't know the history behind the decision to stomp `redhat' in there to begin with nor why it was then dropped later on. But having gotten used to it, people occasionally think the `unknown' (or `pc' for that matter) is a bug."

While Jakub Jelínek thought that providing the "redhat" string provided more information than "pc" or "unknown" Stepan Kaspal argued[2] strongly that reverting to maintaining such a patch was wrong. He suggested that either upstream should be convinced to change the use of "manufacturer" or that the %configure macro in the specfile could be used to explicitly avoid calling config.guess. From here on the thread became too technically detailed to summarize although it is relatively brief as of going to press. Those learned in the lore of autotools and cross-compilation will find much to gladden their hearts.

[edit] Build-time Trapping of Python Syntax Errors

Tim Waugh initiated[1] verification that Python code can be parsed correctly: "[...] since we are already byte-compiling Python code at build time, it is no extra effort to verify that it can be parsed and fail if not."

Reaction was[2] uniformly positive and when Panu Matilainen explained the simple errors which the byte compile would catch and suggested[3] a simple method of determining affected packages Florian Festi took up the challenge.

[edit] YUM Plans for Transition to Fedora 12 i686 Architecture

When Paul Howarth asked[1]: "Now that Fedora 11 x86_32 is going to be based on i586 packages rather than i386 packages, does it follow that yum's $basearch will change from i386 to i586 and hence repository directory layouts changing too, or will it stay at i386?" a brief discussion between Seth Vidal and Josh Boyer started[2] with a discussion over whether repositories should be named after specific architectures.

Seth Vidal differentiated between $arch and $basearch and explained[3]: "The whole reason I liked used $arch was that it meant when fedora stopped producing a 586 compatible tree, we didn't stop any one else from making a 586 compat tree and having it available like secondary arches are." Jesse Keating explained[4] that "i386" was a misnomer for the x86 offering. Josh Boyer was[5] unsure whether i586 would actually "go away" for Fedora 12. Dennis Gilmore was sure that it would and offered[6]: "Anyone who wants to continue i586 support post F11 i look forward to talking to about setting up i586 as a secondary arch."

[edit] L10n Infrastructure Team

In response to PaulFrields' call[1] for putting in place an L10n Infrastructure team, FLSCo announced a 4 member team to oversee the Fedora Localization Project Infrastructure operations[2]. The team includes DimitrisGlezos, DiegoZacarao, AsgeirFrimannsson and AnkitPatel.

[edit] Proposed L10n Infrastructure Plan for Fedora 11

Earlier, DimitrisGlezos had announced[1] a proposed roadmap for the L10n Infrastructure for Fedora 11 Translation period. This included using Transifex version 0.5 for generation and display of statistics in place of Damned Lies and Transifex version 0.3 for submissions. A test interface of this setup is currently available at: http://publictest14.fedoraproject.org/tx/languages/

AsgeirFrimannsson suggested[2] an alternative approach to use the new Django supported version of Damned Lies for statistics and to also test its possible utilisation for translation submission.

[edit]

FLSCo member NorikoMizumoto has requested[1] all the coordinators for the existing Translation Teams to inform about their FAS account names so that they could be upgraded to the role of "Sponsor". This would help the new members in their team to be approved faster.

[edit] Evolving Fedora 11 Artwork

Paul Frields expressed[1] concern on @fedora-art about the artwork process and the Fedora 11 schedule: "The F11 Beta freeze arrives on March 10th, and it would be good to have a background ready somewhat before that so there's time to tweak it before the freeze[.]" In reply[2] Máirí­n Duffy was confident: "I *think* we're going to be okay. I'll know by Monday whether or not we might have an issue." and called for a work session over the week-end "I am going to cram this weekend and try to iterate on what we've got. If anyone's with me, pop in #fedora-art this weekend :)"

In the meantime [[Paolo Leoni and Thomas Kole experimented[3][4] with an alternate concept[5] based on world maps, navigation and ships.

[edit] New Options for Guest Cloning

Cole Robinson posted[1] a patch to enable virt-install to "build a guest around an existing disk image, skipping the OS install step." Cole also posted[2] a patch for virt-clone which allows for cloning from an XML file "rather than require the use of a guest defined on the current connection."

[edit] Obtaining Guest IP Address from the Host

Thomas Mackell inquired[1] about a way to obtain the IP address of a guest that was easier than logging into it and running ifconfig. Cole Robinson pointed out Package-x-generic-16.pngvirt-mem[2] which is a collection of utilities for interrogating KVM guests. Tools included are virt-uname, virt-dmesg, virt-ps, and virt-ifconfig.

[edit] Qemu Packaging and noarch BIOS Firmware

The process [1] of building BIOS firmwares to support architecturally diverse guests on architecturally diverse hosts is very involved and repetitive. Glauber Costa learned[2] of changes coming to Koji which could simplify the process by allowing for bundled BIOS images to be built as "noarch" RPMs. These would be readily available to hosts on any architecture in the repository. Save for some "second class citizens"[3] in the repo.

[edit] Libvirt List

This section contains the discussion happening on the libvir-list.

[edit] Support for Snapshot Volumes

Nick Moffitt asked[1] "Is there any interface to libvirtd that allows it to create volumes that are snapshots of existing volumes?" Daniel P. Berrange pointed[2] out this feature was recently added to Package-x-generic-16.pnglibvirt 0.6.0. "Basically when creating a storage volume, you just need to pass information about the backing storage volume. It'll thus create a volume which is a snapshot of this backing store."

[edit] netcf Network Interface Configuration Library

David Lutterkort has been working on the disconnect between Package-x-generic-16.pnglibvirt and host network interface configuration for some time. (See FWN#159 "Configuring Host Interfaces RFC") [1] "After talking with Dan Williams, who is working in Package-x-generic-16.pngNetworkManager", it became[2] clear to David that solving this problem "is also useful for NM and would help them with handling system-wide interface configuration." David then began work on netcf[3]

Mark McLoughlin complimented[4] the work and updated the shared network interface feature page[5]. The goal of this feature in development is to "Enable guest virtual machines to share a physical network interface (NIC) with other guests and the host operating system. This allows guests to independently appear on the same network as the host machine."
