  32         <p>Some times I try to figure out which Iceweasel browser plugin to
  33 install to get support for a given MIME type.  Thanks to
  34 <a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
  35 done by Ubuntu</a> and Mozilla, it is possible to do this in Debian.
  36 Unfortunately, not very many packages provide the needed meta
  37 information, Anyway, here is a small script to look up all browser
  38 plugin packages announcing ther MIME support using this specification:</p>
  39
  40 <pre>
  41 #!/usr/bin/python
  42 import sys
  43 import apt
  44 def pkgs_handling_mimetype(mimetype):
  45     cache = apt.Cache()
  46     cache.open(None)
  47     thepkgs = []
  48     for pkg in cache:
  49         version = pkg.candidate
  50         if version is None:
  51             version = pkg.installed
  52         if version is None:
  53             continue
  54         record = version.record
  55         if not record.has_key('Npp-MimeType'):
  56             continue
  57         mime_types = record['Npp-MimeType'].split(',')
  58         for t in mime_types:
  59             t = t.rstrip().strip()
  60             if t == mimetype:
  61                 thepkgs.append(pkg.name)
  62     return thepkgs
  63 mimetype = "audio/ogg"
  64 if 1 < len(sys.argv):
  65     mimetype = sys.argv[1]
  66 print "Browser plugin packages supporting %s:" % mimetype
  67 for pkg in pkgs_handling_mimetype(mimetype):
  68     print "  %s" %pkg
  69 </pre>
  70
  71 <p>It can be used like this to look up a given MIME type:</p>
  72
  73 <pre>
  74 % ./apt-find-browserplug-for-mimetype
  75 Browser plugin packages supporting audio/ogg:
  76   gecko-mediaplayer
  77 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
  78 Browser plugin packages supporting application/x-shockwave-flash:
  79   browser-plugin-gnash
  80 %
  81 </pre>
  82
  83 <p>In Ubuntu this mechanism is combined with support in the browser
  84 itself to query for plugins and propose to install the needed
  85 packages.  It would be great if Debian supported such feature too.  Is
  86 anyone working on adding it?</p>
  87
  88 <p><strong>Update 2013-01-18 14:20</strong>: The Debian BTS
  89 request for icweasel support for this feature is
  90 <a href="http://bugs.debian.org/484010">#484010</a> from 2008 (and
  91 <a href="http://bugs.debian.org/698426">#698426</a> from today).  Lack
  92 of manpower and wish for a different design is the reason thus feature
  93 is not yet in iceweasel from Debian.</p>

 114         <p>The <a href="http://wiki.debian.org/AppStreamDebianProposal">DEP-11
 115 proposal to add AppStream information to the Debian archive</a>, is a
 116 proposal to make it possible for a Desktop application to propose to
 117 the user some package to install to gain support for a given MIME
 118 type, font, library etc. that is currently missing.  With such
 119 mechanism in place, it would be possible for the desktop to
 120 automatically propose and install leocad if some LDraw file is
 121 downloaded by the browser.</p>
 122
 123 <p>To get some idea about the current content of the archive, I decided
 124 to write a simple program to extract all .desktop files from the
 125 Debian archive and look up the claimed MIME support there.  The result
 126 can be found on the
 127 <a href="http://ftp.skolelinux.org/pub/AppStreamTest">Skolelinux FTP
 128 site</a>.  Using the collected information, it become possible to
 129 answer the question in the title.  Here are the 20 most supported MIME
 130 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
 131 The complete list is available from the link above.</p>

 214 <p>I am told that PackageKit can provide an API to access the kind of
 215 information mentioned in DEP-11.  I have not yet had time to look at
 216 it, but hope the PackageKit people in Debian are on top of these
 217 issues.</p>

 240       <div class="body">
 241         <p>Yesterday, I wrote about the
 242 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 243 values provided by the Linux kernel</a> following my hope for
 244 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 245 dongle support in Debian</a>.  Using this knowledge, I have tested how
 246 modalias values attached to package names can be used to map packages
 247 to hardware.  This allow the system to look up and suggest relevant
 248 packages when I plug in some new hardware into my machine, and replace
 249 discover and discover-data as the database used to map hardware to
 250 packages.</p>
 251
 252 <p>I create a modaliases file with entries like the following,
 253 containing package name, kernel module name (if relevant, otherwise
 254 the package name) and globs matching the relevant hardware
 255 modalias.</p>
 256
 257 <p><blockquote>
 258 Package: package-name
 259 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 260 </blockquote></p>
 261
 262 <p>It is fairly trivial to write code to find the relevant packages
 263 for a given modalias value using this file.</p>
 264
 265 <p>An entry like this would suggest the video and picture application
 266 cheese for many USB web cameras (interface bus class 0E01):</p>
 267
 268 <p><blockquote>
 269 Package: cheese
 270 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 271 </blockquote></p>
 272
 273 <p>An entry like this would suggest the pcmciautils package when a
 274 CardBus bridge (bus class 0607) PCI device is present:</p>
 275
 276 <p><blockquote>
 277 Package: pcmciautils
 278 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 279 </blockquote></p>
 280
 281 <p>An entry like this would suggest the package colorhug-client when
 282 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 283
 284 <p><blockquote>
 285 Package: colorhug-client
 286 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 287 </blockquote></p>
 288
 289 <p>I believe the format is compatible with the format of the Packages
 290 file in the Debian archive.  Ubuntu already uses their Packages file
 291 to store their mappings from packages to hardware.</p>
 292
 293 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 294 announce the hardware it support in a way my prototype understand.
 295 This allow those publishing packages in an APT source outside the
 296 Debian archive as well as those backporting packages to make sure the
 297 hardware mapping are included in the package meta information.  I've
 298 tested such header in the pymissile package, and its modalias mapping
 299 is working as it should with my prototype.  It even made it to Ubuntu
 300 Raring.</p>
 301
 302 <p>To test if it was possible to look up supported hardware using only
 303 the shell tools available in the Debian installer, I wrote a shell
 304 implementation of the lookup code.  The idea is to create files for
 305 each modalias and let the shell do the matching.  Please check out and
 306 try the
 307 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 308 shell script.  It run without any extra dependencies and fetch the
 309 hardware mappings from the Debian archive and the subversion
 310 repository where I currently work on my prototype.</p>
 311
 312 <p>When I use it on a machine with a yubikey inserted, it suggest to
 313 install yubikey-personalization:</p>
 314
 315 <p><blockquote>
 316 % ./hw-support-lookup
 317 <br>yubikey-personalization
 318 <br>%
 319 </blockquote></p>
 320
 321 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 322 propose to install the pcmciautils package:</p>
 323
 324 <p><blockquote>
 325 % ./hw-support-lookup
 326 <br>pcmciautils
 327 <br>%
 328 </blockquote></p>
 329
 330 <p>If you know of any hardware-package mapping that should be added to
 331 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 332 database</a>, please tell me about it.</p>
 333
 334 <p>It could be possible to generate several of the mappings between
 335 packages and hardware.  One source would be to look at packages with
 336 kernel modules, ie packages with *.ko files in /lib/modules/, and
 337 extract their modalias information.  Another would be to look at
 338 packages with udev rules, ie packages with files in
 339 /lib/udev/rules.d/, and extract their vendor/model information to
 340 generate a modalias matching rule.  I have not tested any of these to
 341 see if it work.</p>
 342
 343 <p>If you want to help implementing a system to let us propose what
 344 packages to install when new hardware is plugged into a Debian
 345 machine, please send me an email or talk to me on
 346 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

 367         <p>While looking into how to look up Debian packages based on hardware
 368 information, to find the packages that support a given piece of
 369 hardware, I refreshed my memory regarding modalias values, and decided
 370 to document the details.  Here are my findings so far, also available

 375 <p><strong>Modalias decoded</strong></p>
 376
 377 <p>This document try to explain what the different types of modalias
 378 values stands for.  It is in part based on information from
 379 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,

 384 <p>The modalias entries for a given Linux machine can be found using
 385 this shell script:</p>

 390
 391 <p>The supported modalias globs for a given kernel module can be found

 401 <p><strong>PCI subtype</strong></p>
 402
 403 <p>A typical PCI entry can look like this.  This is an Intel Host
 404 Bridge memory controller:</p>
 405
 406 <p><blockquote>
 407 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 408 </blockquote></p>
 409
 410 <p>This represent these values:</p>

 419  i   00        (interface)
 420 </pre>
 421
 422 <p>The vendor/device values are the same values outputted from 'lspci
 423 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 424 0600.  The 0600 class is a host bridge.  Other useful bus values are
 425 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 426
 427 <p>Not sure how to figure out the interface value, nor what it
 428 means.</p>
 429
 430 <p><strong>USB subtype</strong></p>
 431
 432 <p>Some typical USB entries can look like this.  This is an internal

 453 <p>The 0900 device class/subclass means hub.  Some times the relevant
 454 class is in the interface class section.  For a simple USB web camera,
 455 these alias entries show up:</p>
 456
 457 <p><blockquote>
 458 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00

 463
 464 <p>Interface class 0E01 is video control, 0E02 is video streaming (aka
 465 camera), 0101 is audio control device and 0102 is audio streaming (aka
 466 microphone).  Thus this is a camera with microphone included.</p>
 467
 468 <p><strong>ACPI subtype</strong></p>

 543 <p><strong>SerIO subtype</strong></p>
 544
 545 <p>This type is used for PS/2 mouse plugs.  One example is from my

 561 <p>This type is supported by the psmouse driver.  I am not sure what
 562 the valid values are.</p>
 563
 564 <p><strong>Other subtypes</strong></p>
 565
 566 <p>There are heaps of other modalias subtypes according to

 568 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
 569 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
 570 vmbus, x86cpu and zorro.  I did not spend time documenting all of
 571 these, as they do not seem relevant for my intended use with mapping
 572 hardware to packages when new stuff is inserted during run time.</p>
 573
 574 <p><strong>Looking up kernel modules using modalias values</strong></p>
 575
 576 <p>To check which kernel modules provide support for a given modalias,
 577 one can use the following shell script:</p>

 579 <pre>
 580   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \

 583   done
 584 </pre>
 585
 586 <p>The output can look like this (only the first few entries as the
 587 list is very long on my test machine):</p>

 634         <p>As part of my investigation on how to improve the support in Debian
 635 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 636 Launcher and updated the Debian package
 637 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 638 sure udev will fix the device permissions when it is plugged in.  I
 639 also added a "Modaliases" header to test it in the Debian archive and
 640 hopefully make the package be proposed by jockey in Ubuntu when a user
 641 plug in his rocket launcher.  In the process I moved the source to a
 642 git repository under collab-maint, to make it easier for any DD to
 643 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 644 is not very active, but the software still work for me even after five
 645 years of relative silence.  The new git repository is not listed in
 646 the uploaded package yet, because I want to test the other changes a
 647 bit more before I upload the new version.  If you want to check out
 648 the new version with a .desktop file included, visit the
 649 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb

 672         <p>One thing that annoys me with Debian and Linux distributions in
 673 general, is that there is a great package management system with the
 674 ability to automatically install software packages by downloading them
 675 from the distribution mirrors, but no way to get it to automatically
 676 install the packages I need to use the hardware I plug into my
 677 machine.  Even if the package to use it is easily available from the
 678 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 679 suggest to automatically install the python-nxt, nbc and t2n packages
 680 I need to talk to it.  When I plug in a Yubikey, it could propose the
 681 yubikey-personalization package.  The information required to do this
 682 is available, but no-one have pulled all the pieces together.</p>
 683
 684 <p>Some years ago, I proposed to
 685 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 686 the discover subsystem to implement this</a>.  The idea is fairly
 687 simple:
 688
 689 <ul>
 690
 691 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 692   starting when a user log in.</li>
 693
 694 <li>Set this program up to listen for kernel events emitted when new
 695   hardware is inserted into the computer.</li>
 696
 697 <li>When new hardware is inserted, look up the hardware ID in a
 698   database mapping to packages, and take note of any non-installed
 699   packages.</li>
 700
 701 <li>Show a message to the user proposing to install the discovered
 702   package, and make it easy to install it.</li>
 703
 704 </ul>
 705
 706 <p>I am not sure what the best way to implement this is, but my
 707 initial idea was to use dbus events to discover new hardware, the
 708 discover database to find packages and
 709 <a href="http://www.packagekit.org/">PackageKit</a> to install
 710 packages.</p>
 711
 712 <p>Yesterday, I found time to try to implement this idea, and the
 713 draft package is now checked into
 714 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 715 Debian Edu subversion repository</a>.  In the process, I updated the
 716 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 717 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 718 the relevant packages in Debian, and uploaded a new version
 719 2.2013.01.09 to unstable.  I also discovered that the current
 720 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 721 package in Debian no longer discovered any USB devices, because
 722 /proc/bus/usb/devices is no longer present.  I ported it to use
 723 libusb as a fall back option to get it working.  The fixed package
 724 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 725 because of the freeze).</p>
 726
 727 <p>With this prototype in place, I can insert my Yubikey, and get this
 728 desktop notification to show up (only once, the first time it is
 729 inserted):</p>
 730
 731 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 732
 733 <p>For this prototype to be really useful, some way to automatically
 734 install the proposed packages by pressing the "Please install
 735 program(s)" button should to be implemented.</p>
 736
 737 <p>If this idea seem useful to you, and you want to help make it
 738 happen, please help me update the discover-data database with mappings
 739 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 740 list the package you would like to have installed when a given
 741 hardware device is inserted into your computer, and report bugs using
 742 reportbug if it isn't.  Or, if you know of a better way to provide
 743 such mapping, please let me know.</p>
 744
 745 <p>This prototype need more work, and there are several questions that
 746 should be considered before it is ready for production use.  Is dbus
 747 the correct way to detect new hardware?  At the moment I look for HAL
 748 dbus events on the system bus, because that is the events I could see
 749 on my Debian Squeeze KDE desktop.  Are there better events to use?
 750 How should the user be notified?  Is the desktop notification
 751 mechanism the best option, or should the background daemon raise a
 752 popup instead?  How should packages be installed?  When should they
 753 not be installed?</p>
 754
 755 <p>If you want to help getting such feature implemented in Debian,
 756 please send me an email. :)</p>
