Hi,

Adam has added a hint to ignore the new RC bug.  Provided it does not
break any reverse dependencies in testing, it should migrate in the next
Britney run.

Fwd: kde/qt debconf not working

2014-01-18 Thread Pali Rohár
Hello,

Kubuntu developers told me to send these patches to Debian, because
perl debconf version is maintaned by Debian. Can you look at patches
and fix these bugs? I'm forwarding original email.

Hello,

it looks like for me that nobody reading debconf bugs on
launchpad... so I resending them to kubuntu-devel list.

problem is that debconf does not work with qt/kde gui backend and
debconf package has missing dependences.

I reported it on launchpad bug tracker more than year ago, see:
https://bugs.launchpad.net/ubuntu/+source/debconf/+bug/988991
https://bugs.launchpad.net/ubuntu/+source/debconf/+bug/988961

Here are patches which fixing that two bugs:

debian-devel is not a bug-fixing forum.

If you believe there are bugs in Debian's debconf package, please file
them in the Bug Tracking System.

RFH: sane-backends FTBFS on buildds, but not in pbuilder

2014-01-18 Thread John Paul Adrian Glaubitz
Hi!

I sponsored a new version of sane-backends today which Mark Buda (CC)
has recently adopted. He has imported the latest upstream version 1.0.24
and fixed some lintian issues.

Unfortunately, this package currently fails to build on the buildds
while it builds fine when building in a pbuilder environment [1].

The builds fails during dh_installdocs which previously worked fine,
the debian/rules file is identical for version 1.0.23-3 and 1.0.24-1,
so the issue must lie somewhere else.

I have already tried removing debhelper's option "--parallel" (since
this resulted in similar issues on some packages before) as well as
changing the source path for the affected file "sane.ps" from
"debian/libsane-common/usr/share/doc/libsane/sane.ps" to
"debian/usr/share/doc/libsane/sane.ps", yet this doesn't fix the issue.

I have used my Launchpad PPA for these tests [2], but without luck so
far.

Anyone has a clue what could be wrong? I can't really wrap my head
around the fact that it builds fine in a pbuilder environment but
not on the actual buildds.

Any help is highly appreciated!

Cheers,

Adrian

Did you try to build it with dpkg-buildpackage -B (i.e. not building
binary-all-packages)? If that works, could you compare the log between
your build and the one on the i386 buildd (and in best case, just
build in an i386 chroot)?

It seems to me that sane.ps is not built.

No, you're right, this could definitely be the reason. Mark changed the
architecture for libsane-common from "any" to "all" which would mean
the package isn't built during a binary-only build!

On the other hand, the Launchpad buildds have to do a full build since
I am uploading source packages only.

>From where do you see that? The build log for i386 actually states

"Generating sane.ps from sane.dvi...".

However, I think the buildd is probably disregarding the package due
to the architecture set to "all" for libsane-common.

Bug#735927: general: X *always* crashes when 5 youtube video opened

2014-01-18 Thread moli
Package: general
Severity: important

Dear Maintainer,

   * What led up to the situation?

The hardware is an Intel D945GCLF2 motherboard with Intel 82945GC MCH and Intel
Atom 330 processor and 1GB ram module. The bios settings: DVMT MODE: DVMT, IGD
DVMT MEMORY: 32MB, IGD APERTURE SIZE: 128MB. There is no swap partition in the
system.
I installed debian 7.3 amd64 with alternative desktop environment xfce by
graphical expert install using english language (because hungarian language
fails at tasksel). After installation i purged a whole lot of packages so the
number of installed packages came down to 800. Then i installed google-chrome-
stable icedtea-6-plugin firmware-linux intel-microcode iucode-tool and
rebooted.

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

I started chrome and opened 5 youtube 10 hour long videoes (i was planning to
test my cooling solution). The processor load was at 80% (!! not 100%!), the
ram was at ~90%.

   * What was the outcome of this action?

In about 1 minute the X crashed. Reproducable any time.
/var/log/Xorg.0.log.old: (EE) intel(0): Failed to submit batch buffer, expect
rendering corruption or even a frozen display: No space left on device.

   * What outcome did you expect instead?

X not to crash.

Apparently, you haven't got free disk space left. That's sort of
expected that when there's no free disk space programs start crashing

I seriously doubt that.  I think that part of the Intel graphics stack
(could be userland or kernel) used ENOSPC to indicate that some GPU
resource was exhausted.

Well, makes sense. It's probably just me who hits disk space problems

My personal experience is that the new pepper-based flash plugin works
much smother with Chromium than the old/classic NPAPI-based one.

You can try to install the package pepperflashplugin-nonfree from the
repository wheezy-backports/contrib

Shouldn't happen if you partition your disks and even then only
carelessly written programs like mythtv and KDE crash or refuse to
start but them two may have been fixed now in this regard.

chrome plugins:
chrome pdf viewer
icedtea-web plugin

widevine
adobe flash player 12.0.0.41

chrome extensions: NONE
chrome apps: NONE

BUT i just disabled the adobeflash plugin so it would use pepper
or html5, and ran the test again, it crashed ~40 seconds later.

I dont have any knowledge in this area but i dont think this has
anything to do with chrome, i think it's an intel graphics driver
issue, it does not handle gracefully when the video memory is gone.

Bug#735927: general: X *always* crashes when ram is full

2014-01-18 Thread moli
ok, another way to reproduce without chrome or flash or youtube:

reboot to a clean system, dont run anything, only an X and a console
# mkdir /tmp/foo
# mount -t tmpfs none /tmp/foo -o size=900m
# dd if=/dev/zero of=/tmp/foo/bar
(a message comes with device full)
(now you cannot give any new command in bash as there is no memory to
start a new shell for you command: error message: "bash: fork: cannot
allocate memory")
now wait a few seconds, move your mouse, etc, boom, the x crashes:
/var/log/Xorg.0.log.old
(EE) intel(0): Failed to submit batch buffer, expect rendering
corruption or even a frozen display: No space left on device.

note: this time i've set the bios parameters to the *MAXIMUM* values:
DVMT MODE: FIXED
IGD DVMT MEMORY: 128MB
IGD APERTURE SIZE: 256MB
so there should be plenty of video memory and note that i didnt run
much program that needs video memory.

Now testing this method on my desktop machine which has 12GB(!) ram and
kdm+kde did not crash the X. The system suffered, lagged but did not
crashed. After filling the tmpfs i opened some new chrome tabs (the
only reason i'm using chrome is nothing else i use eats memory like it),
waited for ~10 minutes, chrome did not respond but did not crash. Then i
allocated some more ram again in the tmpfs, the system console had some
messages it is killing the chrome to free ram, some chrome tabs
"crashed", but the X did not.
After this i've logged out and logged in to my girlfriends account, she
uses xfce. Did the same as above, X did not crash, so it's not looking
like an xfce-bug.
Note that my desktop machine has a video card with DEDICATED video ram.

libtiff5 transition mass bug filing

2014-01-18 Thread Jay Berkenbilt
It's been a little over a month since my announcement to debian-devel
that I would be preparing to remove the tiff3 package from debian and
asking people to switch build dependencies on libtiff4-dev to
libtiff-dev.  There are 64 packages that have a version in either
testing, unstable, or experimental that have a build dependency on
libtiff4-dev.  I'm about to do the mass bug filing.  The text of the
mass bug filing is the following:

-
The libtiff4-dev package is a transitional package that is going to
disappear soon.  Please update your build dependency from libtiff4-dev
to libtiff-dev.
-

At this point, libtiff4-dev has actually been an alias for libtiff5-dev
for several weeks, so this is basically a no-op for almost all
packages.  I am using the user tag libtiff4-dev (with user
q...@debian.org) to mark the bug reports.

Re: Registering a media type for Debian binary packages ?

2014-01-18 Thread Charles Plessy
Hi Guillem, Ian, and everybody,

I attached here is an updated proposal for declaring a mime type for Debian
binary packages, plus a patch against the previous version.

Here is an explanation about my motivation.

As the maintainer of the mime-support package, I receive requests to update the
file /etc/mime.types, to associate file suffixes with media types.  In the
absence of requests, I can get information for new associations from the
Internet Assigned Numbers Authority (IANA).

http://www.iana.org/assignments/media-types

The IANA is very flexible for registering new types and these registrations
include a list of file suffixes to associate with.  (Unfortunately, it is not
machine-readable).

I strongly beleive in the point 2 of our Social Contract, about propagating
changes upstream and “give back to the free software community”.  When I am
requested to add a non-registered type to /etc/mime.types, I am therefore
asking systematically to the requester to consider going through the IANA
first.  (In case the modification is needed for making our next stable release
better, I will of course not stand in the way of an update).

In parallel, the IANA itself, through RFC 6838, welcomes the registration
of new media types.

http://tools.ietf.org/html/rfc6838#section-1.1

See also the paragraph on unregistered types:

“with the simplified registration procedures described above for vendor
 and personal trees, it should rarely, if ever, be necessary to use
 unregistered types.”

http://tools.ietf.org/html/rfc6838#section-3.4

In this context, old unregistered media types starting with 'x-' are
progressifely being registered without this deprecated prefix.

Given the effort I am asking to the people requesting changes in
/etc/mime.types, I would like Debian to give the example as well.

Since the media type of Debian binary packages is unclear (there are at least
two alternative in circulation), I am proposing to register an official media
type in the vendor tree.

While the unofficial types may stay in circulation for a long time, I think
that it is worth the effort, especially given that the work is 90 % done now.

I took care of your other comments directly by changing the text. here are some
answers when it was not possible.

Here, I intend “APT archives” to be about the format, not to suggest that only
apt-get should be used.  I could phrase it better.  Suggestions are welcome.

Indeed, with Epiphany browser or Chrome, no front-end is proposed despite the
media type is indicated in the HTTP headers.  I consider it a bug.  With
Iceweasel, it worked.

Have a nice Sunday.

Security considerations:

Debian binary packages can contain scripts executing arbitrary commands during
installation, which is done with administrator privileges.  It is therefore
essential to trust the origin of the package.  The recommended way is to
download packages from APT (Advanced Packaging Tool) archives that are
authenticated with a trusted cryptographic key (see the manual page of
apt-secure for details).  As a lesser alternative for cases where APT tools are
not available, the package should be downloaded with secured protocols such as
HTTPS.  There also exists a mechanism for signing packages directly (called
‘debsigs’), but it is not deployed.

The contents of the Debian binary packages are placed inside tar archives
