[Bug 261380] Re: Packages have invalid .gnu_debuglink

2008-11-23 Thread Martin von Gagern
Still not fixed in 4.4.3-1ubuntu4_i386 for Jaunty.

I had a typo in comment 9; s/"dbg -x"/"dpkg -x"/

To get some traction here, I think the following should work:
1. (debian/patches/) patch configure to include "CONFIG+=nostrip" in QMAKE_VARS
2. (debian/rules) pass "-no-separate-debug-info" to the configure invocation
3. (debian/rules) call "dh_strip --dbg-package=libqt4-dbg" to separte the 
debugging symbols the Ubuntu way
4. (debian/rules) drop all other packaging instructions for the libqt4-dbg 
package

Right now I don't even have access to my Ubuntu system, so I can't try
this out just now. Might take a few weeks before I can work on this
again, so if you want to experiment in that direction, be my guest.

[Bug 381384] [NEW] mod_deflate with mod_fastcgi gives wrong content-length header

2009-05-28 Thread Martin von Gagern
Public bug reported:

Binary package hint: libapache-mod-fastcgi

When compressing the content generated by mod_fastcgi, mod_deflate will
keep any Content-Length header created by the script, instead of
adjusting the header to match the compressed length.

References:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=509116
http://article.gmane.org/gmane.comp.web.fastcgi.devel/1167

It seems that in surprisingly many cases this problem will go unnoticed by end 
users. Using Trac via FastCGI, however, I have encountered this issue 
repeatedly, and could even capture one instance using wireshark.
What I did was this:
1. Log into Trac account
2. Re-visit /trac/login
3. Get surprised by a Firefox dialog asking me to save the binary file "trac".

The traffic on the wire, starting at point 2 and reduced to the relevant
parts:

> GET /trac/login/ HTTP/1.1
> Keep-Alive: 300
> Connection: keep-alive

< HTTP/1.1 302 Found
< Content-Length: 0
< Location: http://host.name/trac
< Content-Encoding: gzip
< Keep-Alive: timeout=15, max=100
< Connection: Keep-Alive
< 
< [gzipped data, 0 bytes uncompressed, 26 bytes compressed]

> GET /trac HTTP/1.1
> Keep-Alive: 300
> Connection: keep-alive

< HTTP/1.1 301 Moved Permanently
< Content-Encoding: gzip
< Content-Length: 239
< Keep-Alive: timeout=15, max=99
< Connection: Keep-Alive
<
< [gzipped data, 297 bytes uncompressed, 239 bytes compressed]

What happens is this: firefox receives the first response, reads 0 bytes
of content, and either because it didn't find any gzip header in those 0
bytes, or because it gives Content-Length preference over Content-
Encoding in at least this case of a broken HTTP response, it decides
that's it. The first 16 bytes of the gzipped empty content which were
part of the same TCP frame as the headers seem to be discarded. However,
the remaining 10 bytes are still on the wire, in their own TCP frame.

Next, FF sends a request for the next location. In this case, it matches
a Redirect directive in my Apache configuration, so the next reply is
generated by Apache itself, not through mod_fastcgi. The response is all
right, but unfortunately, when reading it, FF first receives those 10
bytes left over from the last request. Seeing binary data instead of
headers, it decides this must be a bad server sending binary content
without headers, and offers to save this assumed binary file. When
loking at the file, it's those 10 bytes, followed by the headers and
compressed content for the next reply.

I had a look at some non-empty responses generated by
trac/fast_cgi/mod_deflate, and they, too, have Content-Length headers to
match the uncompressed content. In those cases, however, it seems FF
uses the gzip end-of-data encoding instead of relying on the Content-
Length header. So the HTTP protocol is still violated, but the browser
is lenitent enough so users won't notice.

http://article.gmane.org/gmane.comp.web.fastcgi.devel/1167 gives a good
indication as to what's causing this problem. Seems that mod_fastcgi
copies all headers sent by a script to err_headers_out, with the
exception of a few well known like "Location", which it copies to
headers_out instead. There is even a patch to do the same special-case
handling for Content-Length, but the author argues that other headers
might require similar behaviour.

The Debian bug does indicate libapache2_mod_fcgid as an alternative
which doesn't exhibit this behaviour. It is not an easy drop-in
replacement, though, as it doesn't accept extra path components after
the file name in a ScriptAlias, and as the Apache configuration has to
be changed due to a different module file name for IfModule checks and
different configuration directives. So simply switching is not always a
solution.

http://thread.gmane.org/gmane.comp.web.fastcgi.devel/2613 indicates
another approach towards a solution, and it seems that a variation of it
has been committed to some mod_fastcgi repository (though not the git at
http://repo.or.cz/w/mod_fastcgi.git). It's also available in a snapshot
dated 0811090952, but hasn't been officially released yet. The chunk in
question is this one:

[Bug 381384] Re: mod_deflate with mod_fastcgi gives wrong content-length header

2009-05-28 Thread Martin von Gagern
For those interested in mod_fastcgi development in general, or in the
greater context of the upstream fix, I'm attaching a diff between the
2.4.6 release and the SNAP-0811090952 snapshot source tree. I've written
to the fastcgi-developers mailing list, pointing at this issue here and
asking as to when a release containing this fix can be expected. As I'm
not subscribed to the list, my post is still awaiting approval.

Comparison of the possible fixes:

http://www.yl.is.s.u-tokyo.ac.jp/~oiwa/pub/unix/fastcgi-content-length.patch
Uses headers_out, errors on duplicate Content-Length headers.

http://article.gmane.org/gmane.comp.web.fastcgi.devel/2613
Uses ap_set_content_length instead of headers_out.

SNAP-0811090952 according to attached patch
Uses headers_out, no check for duplicate Content-Length headers.

The snapshot also removes duplicate header checks in other cases, so this is 
consistent.
For the Content-Type header there is a case distinction, and it uses 
ap_set_content_type for APACHE2. ap_set_content_length sounds like a 
counterpart to this, but I guess upstream had reasons to change the patch from 
the one sent to them, and Content-Type was somwhat different in Apache 1 builds 
as well, as it had a dedicated field instead of the headers_out table.

On the whole, I'd go with the upstream changes.

[Bug 336401] Re: Xorg crashed with SIGSEGV in ActivateDevice() - wacom tablet

2009-04-17 Thread Martin von Gagern
Making progress. Added a DebugLevel option with a value of 10 to the
wacom sections in xorg.conf. Also found out that the package xserver-
xorg-core-dbg containing the required Xorg debug symbols does exist, it
just isn't printed by dpkg -l. With those tools in place, the situation
looks like this:

First, the devices are activated via InitInput:
#0  xf86WcmDevOpen (pWcm=0x911c700) at ../../../src/xdrv/xf86Wacom.c:783
#1  0xb6bbdc2f in xf86WcmDevProc (pWcm=0x911c700, what=0) at 
../../../src/xdrv/xf86Wacom.c:1034
#2  0x0808662f in ActivateDevice (dev=0x911c700) at ../../dix/devices.c:447
#3  0x080d8c7e in xf86NewInputDevice (idev=0x8f53450, pdev=0xbfd9dddc, enable=1 
'\001')
at ../../../../hw/xfree86/common/xf86Xinput.c:544
#4  0x080ae3c6 in InitInput (argc=2, argv=0xbfd9dec4) at 
../../../../hw/xfree86/common/xf86Init.c:1328
#5  0x0807229a in main (argc=2, argv=0xbfd9dec4, envp=Cannot access memory at 
address 0x6c
) at ../../dix/main.c:369

As the device isn't plugged in, initialization fails, which is to be
expected.

Next, the device is uninitialized, still from within InitInput:
#0  xf86WcmUninit (drv=0x8f59cd8, local=0x911c658, flags=0) at 
../../../src/xdrv/wcmConfig.c:367
#1  0x080d8bf7 in xf86NewInputDevice (idev=0x8f53450, pdev=0xbfd9dddc, enable=1 
'\001')
at ../../../../hw/xfree86/common/xf86Xinput.c:562
#2  0x080ae3c6 in InitInput (argc=2, argv=0xbfd9dec4) at 
../../../../hw/xfree86/common/xf86Init.c:1328
#3  0x0807229a in main (argc=2, argv=0xbfd9dec4, envp=Cannot access memory at 
address 0x20

As part of the uninit, priv gets freed:
xf86WcmUninit (drv=0x993acd8, local=0x9afd658, flags=0) at 
../../../src/xdrv/wcmConfig.c:383
383 xfree(priv);

Later on, the device gets initialized again, this time via InitAndStartDevices:
#0  0xb6b8daa0 in xf86WcmDevProc (pWcm=0x9afd700, what=0) at 
../../../src/xdrv/xf86Wacom.c:1014
#1  0x0808662f in ActivateDevice (dev=0x9afd700) at ../../dix/devices.c:447
#2  0x08086732 in InitAndStartDevices () at ../../dix/devices.c:637
#3  0x0807229f in main (argc=2, argv=0xbfb6bc94, envp=0x0) at 
../../dix/main.c:370

The problem is the xfree(priv) in xf86WcmUninit. It is guarded by a
#ifndef WCM_XORG_XSERVER_1_6 preprocessor switch, and the comment seems
to indicate the issue we experience, but somehow this preprocessor magic
fails.

>From what I can tell, configure correctly detects the version and sets
its shell variable WCM_XORG_XSERVER_1_6 accordingly. Looking at the
build log for this line should verify this:

checking if Xorg is version 1.6 or later... yes

It seems that the shell variable from make doesn't get turned into a
preprocessor switch. Adding that flag to CFLAGS in debian/rules is easy,
though rather hackish. Doesn't completely solve the issue, though, only
makes me progress a bit farther. Up to the next call to xf86WcmDevOpen,
to be precise. At that point, priv has changed, and its common pointer
is NULL.

Adding a watchpoint for the memory address of the private pointer, I
find it gets set to zero in a xalloc call in xf86WcmInit, for the second
round of initialization from InitAndStartDevices. So it seems the local
data was freed, but still got reused.

Now the basic question is this: is it correct that the X server tries to 
initialize the wacom devices twice?
If yes, then either the private data shouldn't be freed, or new private data 
allocated. If not, then that should be avoided.

It seems upstream changed its opinion as to how to deal with this issue in 
Uninit:
http://linuxwacom.cvs.sourceforge.net/viewvc/linuxwacom/linuxwacom-dev/src/xdrv/wcmConfig.c?r1=1.36&r2=1.37#l377

They also addressed the config issue by now:
http://linuxwacom.cvs.sourceforge.net/viewvc/linuxwacom/linuxwacom-dev/configure.in?r1=1.99&r2=1.100#l457

The upstream solution of always deleting the input doesn't work for me.
Instead, if I include the xf86DeleteInput in the block guarded by
WCM_XORG_XSERVER_1_6, then at least my X starts up. I'll have to try
actually using a Wacom device with that setup, but I won't do so today.
See attached debdiff for what I changed.

2009-03-10 Thread Martin von Gagern
Can some Ubuntu qt packager please have a look at this?

I've put quite a lot of personal time, and even more computer runtime,
into trying to get this fixed. I've posted the relevant modifications as
well as instructions how to integrate them. I'm clobbering my PPA with
almost 1 GiB of packages for this, even though they have been outdated
less than a month after publishing them.

On the other hand, this bug hasn't seen much useful comments from devs since 
about 5 months. I would like to know
1. whether you are going to fix this for Jaunty, in order to get usable qt 
backtraces there
2. whether my patches lead in the right direction, or if they are unacceptable 
for some reason
3. whether it makes sense to update my PPA, or if I should simply delete those 
packages 'cause noone else cares
4. whether the updated intrepid packages might be placed in some team PPA, to 
save space in my own PPA

To use the libQtGui.so.4.4.3 from 4.4.3-0ubuntu1 on i386 as an example:
here /usr/lib/libQtGui.so.4.4.3.debug has a crc32 value of 0x61598269,
computed using the algorithm given in the gdb manual and compared
against one calculated using objcopy. The .gnu_debuglink section of
/usr/lib/libQtGui.so.4.4.3 states 0x18743161. I manually converted
endianess; objdump displayed reverse byte order in both cases.

As to the cause of this issue: I just had a look at the build log from
https://launchpad.net/ubuntu/+source/qt4-x11/4.4.3-0ubuntu1/+build/729722
and found the following line:

(test -z "../../lib/" || cd "../../lib/" ;
targ=`basename libQtGui.so.4.4.3`;
objcopy --only-keep-debug "$targ" "$targ.debug" &&
objcopy --strip-debug "$targ" &&
objcopy --add-gnu-debuglink="$targ.debug" "$targ" &&
chmod -x "$targ.debug" ) ;

So there the link seems to get set correctly, according to the Fedora
scheme, including the .debug extension and presumably with the correct
checksum as well. Something seems to modify the installed so file later
on, or perhaps the file modified by above command isn't even the one
installed later on. I couldn't find any likely command actually naming
libQtGui, but it might be a command using a glob, or I might have
overlooked something. Strange.

Generating separate debug files according to Fedora naming scheme seems
to be the default configuration of the qt4 build process. A viable
solution to both solve the broken links and also get the package to
follow the preferred Ubuntu naming scheme would be to disable both debug
symbol separation and stripping from the Qt build process, and instead
do the debug symbol separation later on the Ubuntu way, with whatever
tools other packages might use.

Looking at Gentoo, the way to achieve this seems to be to pass -no-
separate-debug-info to configure and CONFIG+=nostrip to qmake. As
Ubuntu, in contrast to Gentoo, doesn't seem to invoke qmake directly, I
don't know how to achieve this. A viable solution would probably to
include it in the default value of QMAKE_VARS in the configure script.

[Bug 293126] Re: kmix crashes with SIGABRT

2008-11-06 Thread Martin von Gagern
After installing kdemultimedia-dbg I could use a running kmix instance
to get more information from the files posted here. To do so, I compared
the maps attached here with that of the running process in order to
relocate the addresses mentioned in the backtrace to the corresponding
addresses in the running process. Using the list command in gdb I could
get function name and source file information about these addresses. As
the addresses represent return addresses from the call stack, they seem
to correspond to the command immediately after the one currently
executing.

With this information I could get more details for two important stack frames:
#12 0xb7a1057a in ?? () from /usr/lib/libsolid.so.4
Solid::DeviceManagerPrivate::_k_deviceAdded(QString const&)
(kde4libs-4.1.2/solid/solid/devicemanager.cpp:165)
#13 0xb7a1087f in ?? () from /usr/lib/libsolid.so.4
Solid::DeviceManagerPrivate::qt_metacall(QMetaObject::Call, int, void**)
(kde4libs-4.1.2/obj-i486-linux-gnu/solid/solid/devicemanager_p.moc:76)

So what happens is that the first assertion in _k_deviceAdded failed, which 
reads
Q_ASSERT(dev->backendObject()==0);
See 
http://websvn.kde.org/tags/KDE/4.1.2/kdelibs/solid/solid/devicemanager.cpp?view=markup

>From there on things get a bit tricky to debug, as I don't have the moc
files generated here, only the sources unpacked, and as I can't get
deeper in the stack, because debugging qt4 is impossible due to bug
261380. On the other hand, "_k_deviceAdded SIGABRT" give pretty good
keywords for a web search, which yielded
http://bugs.kde.org/show_bug.cgi?id=171499 about kmix, which got duped
to http://bugs.kde.org/show_bug.cgi?id=160221 about solid in general,
affecting other apps as well.

Another observation: Debian (tested with sid packages) also uses Fedora layout

they differently?
1. mention *.debug in debian/not-installed
2. some differences in debian/rules that I don't completely understand
3. several other differences that seem unlikely to have anything to do with this
4. using debian tools instead of ubuntu ones to build things

[Bug 261380] Re: Packages have invalid .gnu_debuglink

2008-11-06 Thread Martin von Gagern
It isn't necessary to update to Jaunty just to check this. It would be
enough to get a library package unpacked so you can objdump it, and to
compare the file name mentioned there with those from the dbg package
file list. "dbg -x" would do the former, while the latter might be
possible without even downloading the package itself.

Unfortunately it looks like the 1ubuntu1 build is too brand new. The
links to the binary packages on the page you referred to lead to
launchpad error pages, and packages.ubuntu.com is still taking about
version 0ubuntu1. So if you can lay your hand on these packages, you
might try this out, but I didn't manage to yet.

[Bug 277038] [NEW] landscape-common.postinst stuck with defunct who

2008-10-02 Thread Martin von Gagern
Public bug reported:

Binary package hint: landscape-common

During an update of Intrepid (I think from Alpha 6 to Beta), Adept was
updating landscape-common for several minutes without any progress.
Investigating the issue with ps got me this process call stack:

/usr/bin/dpkg --status-fd 3 --configure 
/usr/bin/perl -w /usr/share/debconf/frontend 
/var/lib/dpkg/info/landscape-common.postinst configure
/bin/sh /var/lib/dpkg/info/landscape-common.postinst configure

/bin/sh /etc/update-motd.d/50-landscape-sysinfo
/usr/bin/python /usr/bin/landscape-sysinfo
[who] 

Looks like who terminated, but landscape-sysinfo wasn't ready for dead
children. Killing who gave no result, neither with SIGTERM nor with
SIGKILL. SIGKILL to its parent, landscape-sysinfo, however resulted in
Adept resuming its operations. landscape-common wasn't listed in the
output of "dpkg --audit" after all of this, but I don't know whether the
update actually worked as expected despite this problem.

I've been using Adept to upgrade Intrepid (from Alpha 6 to Beta, I

2008-10-03 Thread Martin von Gagern
Yes. The "tree" starting at dpkg was linear, with one child for each
process, except for who which was a leaf.

I just had a look at the code. /usr/lib/python2.5/site-
packages/landscape/lib/sysstats.py uses
twisted.internet.utils.getProcessOutputAndValue to call "who -q".
Therefore the actual cause of this bug might also lie in python-twisted-
core, which might for some reason have failed to reap this dead child.
Should this bug here therefore be marked as affecting twisted as well as
landscape-client?

I cannot reproduce the issue by calling landscape-sysinfo manually. If I
hadn't been in such a hurry, I might have thought of stracing landscape-
sysinfo, but it's too late for that now.

[Bug 277669] [NEW] release upgrade to Kubuntu Intrepid removes adept

2008-10-03 Thread Martin von Gagern
Public bug reported:

Binary package hint: adept

When I updated from Hardy to Intrepid Alpha 6 using "do-release-upgrade
-d", adept got removed in the process. apt.log said: "Package adept has
broken dep on adept-common". No problem for me, as I could reinstall it
on the command line, but users used to graphical tools might be in
trouble without their package manager.

I had discussed this on IRC: 
http://irclogs.ubuntu.com/2008/09/22/%23ubuntu+1.html
I had the impression that mvo would further investigate the issue. Perhaps the 
fix for bug 274706 was an attempt at this, I'm not sure.

The problem seems not solved, though, as HappySmileMan just reported the
same thing on IRC just now for Beta: "adept says it will remove adept".

[Bug 269189] Re: [WISH][Kubuntu 8.10 Alpha 5] Add multirows task manager as a option

2008-10-03 Thread Martin von Gagern
Has there been any followup discussion for this? Can you point users to it?
Why is this marked invalid, and not on the wishlist like similar bugs, e.g. bug 
260094?

I consider not having multiple rows a regression, as it severely limits
the number of application windows I can manage simultaneously, and thus
my productiveness. This should be addressed, and having a package for
the multirows task manager plasmoid sounds like a viable way to address
this.

I'd also say that this bug report here, where people interested in that
one single issue can subscribe and keep up to date, is preferable to
some general community mailing lists. I'll not subscribe to a mailing
list just for this, but I'd love to hear more input on this here on
launchpad.

I'm not sure enough to completely rule that out, but it sounds unlikely
to me, for the following reasons. Either lanscape-sysinfo itself would
be asking a question. That doesn't seem to be in its job description,
especially when called without parameters, so I think this unlikely. Or
some other process would be asking a question. Then there would be
nothing to prevent lanscape-sysinfo from reaping its defunct child.
Ergo, no questions involved.

[Bug 280269] [NEW] icons differ only in color

2008-10-08 Thread Martin von Gagern
Public bug reported:

Binary package hint: knetworkmanager

I just noticed that knetworkmanager in Intrepid does display its globe
icons in two different colors, green for connected and gray for
unconnected. Otherwise the icons look the same, with similar intensity
and same object depiceted. I think this is a problem for several
reasons:

1. People tend to associate meaning with the objects they see, i.e. "globe" 
instead of "green coloured globe centered at equator and prime meridian, with 
light continents on darker ground".
I saw a globe, moved the mouse over it, learned that it was network manager in 
connected state. Next time around, I saw a globe, found out my network to be 
disconnected, and thus concluded erroneously that there was no state expressed 
by the icon. I simply didn't remember the color of the icon, as for me the 
mental term "globe" seemed sufficient to remember this.

2. A considerable percentage of Kubuntu users is probably to some degree
color blind. As slight color blindness won't impact computer use in
general, they are unlikely to have special accessibility features
activated. So they wouldn't have special icon themes installed, and thus
have to use tool tips in order to find out the current state.

3. The network manager is usually pretty close to a corner of the
screen, an area where on some monitors and in some working environments
color might begin to depend on viewing angle. So you learn not to put
too much trust in colors in these regions, and thus won't notice the
difference easily.

All this would be solved by a symbol with more distinctions than just
its color. A red bar in front of the globe would be the obvious
solution, but the more creative people might think of something more
inspired.

I guess fixing this for the intrepid release might be a problem, so long
after the user interface freeze. On the other hand, the main Ubuntu docs
stay unaffected, only Kubuntu would be affected.

[Bug 280926] [NEW] property 'Disable NAT Traversal' invalid or not supported

2008-10-09 Thread Martin von Gagern
Public bug reported:

Binary package hint: knetworkmanager

This is Intrepid beta with these packages:
network-manager-kde 1:0.7svn864988-0ubuntu1
network-manager-vpnc 0.7~~svn20080928t225540-0ubuntu1
vpnc 0.5.1r275-1ubuntu1

Trying to connect to a vpn using network-manager-vpnc failed without any
error message in knetworkmanager. Looking at /var/log/daemon.log I found
this:

NetworkManager:   Starting VPN service 
'org.freedesktop.NetworkManager.vpnc'...

service pid 8161 to exit 
NetworkManager:  [1223576517.524943] ensure_killed(): vpn service pid 
8161 cleaned up 

Looking at the sources for all the packages in volved, I found that
network-manager-vpnc doesn't mention "Disable NAT Traversal" at all, and
vpnc only has it in its translations. network-manager-kde is the only
package with the string included verbatim in its active sources. So I
take it that knetworkmanager is trying to talk to a pervious incarnation
of vpnc, and that the current version no longer has this option.

Looking at the vpnc svn repository, this option was last seen in the
0.3.3 release of vpnc, dating from 2005. It was removed from trunk in
r98. An online diff is availavle from http://bazaar.launchpad.net/~vcs-
imports/vpnc/trunk/revision/94 . I guess the strict options checking was
added more recently.

The correct replacement string would probably be "NAT Traversal Mode none" for 
the case of disabled NAT traversal and "NAT Traversal Mode natt" for the 
default enabled NAT traversal. A dropdown to select values from might provide 
more flexibility, but also make it harder for novice users to understand. Once 
that string is fixed, knetworkmanager will next complain about "Enable Single 
DES", for which the values "yes" and "no" are expected, not "1" and "0":
'invalid boolean property 'Enable Single DES' (not yes or no)'

Users who want to work around this issue might edit their
.kde/share/config/knetworkmanagerrc manually. For inclusion into ubuntu
as well as upstream sources, I'll also attach a patch. If you patch your
network-manager-kde or install an official Ubuntu package with this fix
in place, you'll have to remove and recreate your vpnc configuration, as
it seems the old settings won't go away even when you edit an existing
configuration.

[Bug 281367] [NEW] sysfs_get_link doesn't handle directory symlinks (except as last arc)

2008-10-10 Thread Martin von Gagern
Public bug reported:

Binary package hint: libsysfs2

Involved packages:
pmount 0.9.17-2
libsysfs2 2.1.0-4
linux-image-2.6.27-6-generic 2.6.27-6.9

I observed this problem while trying to use pmount. Relevant lines only:
$ pmount /dev/sdb1
Error: device /dev/sdb1 is not removable
$ pmount --debug /dev/sdb1
device_removable: could not find a sysfs device for /dev/sdb1
$ sudo ltrace -s 1024 pmount /dev/sdb1
sysfs_get_link("/sys/block/sdb/device", "/2:0:0:0", 1024) = 0
sysfs_open_device_path("/2:0:0:0") = 0
$ readlink /sys/block/sdb/device
../../../2:0:0:0
$ readlink /sys/block/sdb
../devices/pci:00/:00:1d.0/usb1/1-1/1-1:1.0/host2/target2:0:0/2:0:0:0/block/sdb
$ ( cd /sys/block/sdb/device; pwd -P; )
/sys/devices/pci:00/:00:1d.0/usb1/1-1/1-1:1.0/host2/target2:0:0/2:0:0:0

So the symlink does point to a valid device directory when all symlinks
in the path are considered or, alternatively, when .. is treated like
any subdirectroy and not canceled with the preceding arc. The
sysfs_get_link function, however, cancels arcs without checking for
symlinks. This leads to an incorrect absolute path, and thus causes
pmount to fail.

I'm not perfectly sure whether sysfs_get_link is intended to deal with
such issues. Looking at libsysfs.txt shipped with the sysfsutils sources
I would guess so, though. And as sysfsutils is a probably security
relevant piece of code, I'd rather play it safe, and have the library
perform some extra checks instead of relying on applications to take
care of such details. On the other hand, if this issue were to take
longer to get fixed, pmount could probably work around it by simply not
calling sysfs_get_link at all, but instead have the OS deal with
symlinks.

Looking at the code of sysfs_get_link from sysfs_utils.c, it looks like
this issue might cause more severe problems. This is the part where the
path stripping actually happens, having detected the link path (d) to
start with "..":

  while (*d == '/' || *d == '.') {
if (*d == '/')
slashes++;
d++;
  }
  d--;
  s = &devdir[strlen(devdir)-1];
  while (s != NULL && count != (slashes+1)) {
s--;
if (*s == '/')
  count++;
  }
  safestrcpymax(s, d, (SYSFS_PATH_MAX-strlen(devdir)));

As you can see, the code moves backwards in the directory path. However,
the beginning of string comparison seems to me completely bogus. So when
there aren't enough slashes, this code will iterate before the beginning
of the string. I guess it should be something like "s != devdir" instead
of "s != NULL".

The assumption that there will be only arcs of the form ".." involved,
no "." or "" isn't completely justified either, although it should
for the most part hold in sysfs.

I guess one could also modify this loop to replace every '/' by '\0' and
check the thus truncated path recursively. I'm not perfectly sure
whether one would have to take special care in order to prevent infinite
loops; on sane file systems I wouldn't think so.

[Bug 281407] [NEW] kfmclient won't exit after calling firefox

2008-10-10 Thread Martin von Gagern
Public bug reported:

Binary package hint: konqueror

I've configured my kubuntu intrepid beta to use firefox as my default
browser. I called ubuntu-bug and got a new tab in my already running
firefox. As the invoked second instance of the firefox application only
acted as a remote control, it should have returned immediately.
Nevertheless, ubuntu-bug remained running, even after I closed first the
bug report tab and then firefox itself. I can reproduce the issue
calling "kfmclient openURL https://bugs.launchpad.net/"; on the command
line. As kfmclient employs two threads at this moment, I have a bit of
trouble debugging this. I still haven't figured out how to get
backtraces of all threads. I hope that apport managed to do so in this
report here. The console output reads thus:

[Bug 279240] [NEW] firefox dies mentioning RenderBadPicture and a failed assertion

2008-10-06 Thread Martin von Gagern
Public bug reported:

Binary package hint: firefox

firefox is extremely unstable on my intrepid at the moment. It dies
repeatedly without any discernible common cause. When started from the
command line, the error messages look like this:

QPixmap: Invalid pixmap parameters
The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 3484417 error_code 176 request_code 152 minor_code 7)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful

[Bug 279642] [NEW] Provide Retry option for Network Manager

2008-10-07 Thread Martin von Gagern
Public bug reported:

Binary package hint: network-manager-kde

I observedthis on Intrepid beta, but I think it's probably going to
become a wishlist item targeted at a later release.

I had just plugged in my LAN network cable, and the kde network manager
applet displayed the usual turning gear while trying to negotiate IP
settings. However, there seemed to be problems, perhaps due to the fact
that my lan link here is rather weak, only 10Base-T, and might well
cause high packet drop rates. So after a while, network manager gave up,
and displayed the link as "Disconnected". I checked the connection,
removed the cable, plugged it back in, but I couldn't get network
manager to try again. I had a look at the device using wireshark, there
were even broadcast packets arriving, but no outgoing DHCP requests. So
in the end I invoked dhclient3 via sudo, which got my NIC configured.
Downside of this approach is that e.g. firefox still thinks I'm offline.

Things would be much easier if there was an option labeled "Retry" or
"Repair network connection" or whatever in the network manager applet
that told it to treat the interface as newly connected.

This would also be of advantage in cases where the ethernet link to the
next switch works all right, but the dhcp server is down or unreachable
for any other reason. When it comes back up, you want to reactivate your
connection with a single click, instead of waiting, unplugging cables
and so on.

When you start adding user commands to the network manager frontends,
you might also implement a command to abort the current connection. This
is especially important in wireless networks, where you are not sure of
the encryption password. When you are trying one possibility after the
other, you don't want to wait for the connection to time out in between,
but abort it after a couple of seconds. Perhaps this should be a
separate bug report; if so, please tell me.

[Bug 279570] [NEW] Missing include file taskmanager/taskmanager_export.h

2008-10-07 Thread Martin von Gagern
Public bug reported:

Binary package hint: kdebase-workspace-dev

This is an issue with the header files installed in several kde
development packages in intrepid.

The header files taskmanager/task.h taskmanager/taskmanager.h from
kdebase-workspace-dev 4:4.1.2-0ubuntu5 reference a header file called
taskmanager/taskmanager_export.h which is not installed with the
package.

Building the package from source, there is no reference to this file,
and some other headers are included as "startup.h" and "task.h" instead
of  and . So something seems
to modify this header in the official package that doesn't do so when I
build it from source. Strange.

There are several other packages on my system showing similar issues,
i.e. mentioning *_export.h header files which are not available. Those
packages are kdelibs5-dev, kdepimlibs5-dev and libplasma-dev. This list
probably isn't exhaustive, as I don't have all KDE dev packages
installed. Should I report separate bugs for each of these, or rather
mark this bug here as affecting those as well?

[Bug 279541] [NEW] Stuck shift mode in text mode console

2008-10-07 Thread Martin von Gagern
Public bug reported:

Binary package hint: linux-image-2.6.27-5-generic

This is Kubuntu Intrepid Beta with linux-image-2.6.27-5-generic version
2.6.27-5.8 on an i686 Dell notebook. I assume it might be a kernel
issue, but I'm not sure.

Steps to reproduce:
1. Ctrl+Alt+F2 to change to vt2
2. Log in
3. Alt+F7 to change to kdm
4. Press and hold shift key
5. Select "Restart X server" from kdm menu
6. Wait for X to restart, no need to wait for kdm
7. Release shift key
8. Ctrl+Alt+F2
9. Type some text

Actual result: Shift key seems to be stuck
- Letters in upper case by default. Lower case letters possible through caps 
lock.
- Shifted symbols also for digit and punctuation keys. No way to enter digits 
or unshifted punctuation marks.
- Alt+Fx or Ctrl+Alt+Fx won't work, so no way to switch vt any more.
- Pressing and releasing shift keys (both left and right) doesn't solve the 
issue.
- Entering the password to sudo might be impossible for passwords containing 
digits or similar, leaving the power button as the only possible way to shut 
down the system.

I encountered this issue in "real live" while investigating some other
bug rendering my KDE session unusable. I was restarting kde sessions and
X servers quite frequently on vt7, and typing commands on vt2 in
between. I guess the system might have switched to the login screen on
vt7 automatically while I was just holding shift to enter a command. I'm
not sure about the exact steps, so I'm happy I could provide the easier
steps above, even if they seem somewhat artificial.

2008-10-07 Thread Martin von Gagern
> I doubt that this does not happen when building from source.

Do you doubt my word? To clarify: the problem didn't happen here, not
because the taskmanager_export.h got installed (which wasn't the case),
but because taskmanager.h no longer refered to it. In that sense, the
summary of this bug mentioning a "missing file" is only a problem
description, I don't wish to express that the issue should be fixed by
providing such a file.

Steps to reproduce:
1. sudo apt-get build-dep kdebase-workspace-dev
2. apt-get source kdebase-workspace-dev
3. cd kdebase-workspace-4.1.2
4. dpkg-buildpackage -rfakeroot -uc -b

Tells me that some file called taskmanager.h gets installed, and
probably no taskmanager_export.h. Doesn't say a word about whether or
not the taskmanager.h references a taskmanager_export.h or not. For that
see the source of the header:

> Anyway, please report individual bugs

I'll report the others seperately once this here is done, to avoid
redundant discussion.

To report this upstream I'd have to explain how KDE is to blame for the
ubuntu package containing a file so different from the one shipped with
the KDE sources. As I can't even reproduce this different file, I think
it unlikely that the cause lies somewhere in the KDE managed code.
Unless you convince me otherwise, I'll consider this an Ubuntu bug.

Right now, the issue looks to me as if the ubuntu packager had slipped
some modified header file into the package at some point during the
packaging process, without any reference in the rules file or anywhere
wlse in the debian directory. As the taskmanager.h in the source tree
stays unmodified during the build, and no taskmanager_export.h seems to
get generated, I cannot account for this file in any other way. But I'm
not that experienced in either Debian packaging or KDE development, so
maybe there is some way I didn't know about, which does such
modifications but won't affect my local builds.

[Bug 279240] Re: firefox dies mentioning RenderBadPicture and a failed assertion

2008-10-07 Thread Martin von Gagern
I wonder whether this might be related to gtk-qt-engine. Reasons for
this:

My firefox worked all right on hardy with KDE 3.5.
http://ubuntuforums.org/showthread.php?p=5739519 however mentions the
issue on hardy with KDE 4.1. So KDE 4.1 might be somehow involved.

The backtrace mentions quite a lot of QT 4 methods.

My firefox had general problems with widgets; the tabs lost their frames
after a mouse over highlight, the scrollbars would occasionally display
only half a knob, and after scrolling I had a high chance of widgets
within the page getting rendered with no border. All of this went away
when I changed my GTK engine.

I've changed my GTK engine to Raleigh, and so far things seem to work.
The problem is that with seemingly random failures, you can never be
sure that the issue is really resolved.

With this setup, the kdm init script /etc/init.d/kdm from kdm

[Bug 234340] [NEW] Allow configuration of dhcp client implementation

2008-05-23 Thread Martin von Gagern
Public bug reported:

Binary package hint: ifupdown

On my system, for reasons I don't completely understand yet,
dhcp3-client fails to register a host name with the DSL gateway, an AVM
Fritz!Box. dhcpcd, on the other hand, works well enough, wenn called on
the command line. While I'll try figure out where the difference
actually lies, the simplest solution would be to have ifupdown use
dhcpcd for that devide. Right now the only way to do so seems to
uninstall all other dhcp clients. As this is a notebook, and I've
already encountered scenarions where one client would work and another
won't, that's not a solution I would aim for.

Much preferable would be a config option "implementation" or some such
in the interfaces file, which I could set to "dhcpcd" in order to get
that behaviour.

An addition to this would be some kind of script-based plug-in system
that would allow information about new clients and how to call them to
be bundled with the client instead of the ifupdown package. Looking at
inet.defn in the sources, that should be possible fairly easy. But all
this is only if someone wants to do some more intense work here; for the
time being, the set of client implementations seems complete enough.

[Bug 235612] [NEW] /sbin/lrm-video: Error in regexp

2008-05-28 Thread Martin von Gagern
Public bug reported:

In /sbin/lrm-video the sed expression for nvidia in one instance
contains [ \\t] instead of [ \t], causing xorg.conf files with tabs to
get interpreted incorrectly, which results in the module not getting
loaded though it is used.

[Bug 235899] [NEW] 3Com 3CRSHPW_96 (atmel) defers halt

2008-05-29 Thread Martin von Gagern
Public bug reported:

Binary package hint: network-manager

Shutting down my notebook takes ages. It will display "Will now halt"
for over a minute, so the splash times out and I get to see the text
console. Only happens when my WLAN controller is inserted. At the time
when that message displays, the only processes running are these, apart
from kernel daemons:

/usr/sbin/NetworkManager --pid-file /var/run/NetworkManager/NetworkManager.pid
/bin/sh /etc/init.d/rc 0
/bin/sh /etc/rc0.d/S90halt stop

After waiting those ages, the system displays three more lines. In order
to be able to read them, I had to set HALT=halt in /etc/default/halt.
With that setting I got these lines copied down:

* Will now halt
[TIMESTAMP] wlan: firmware atmel_at76c502_3com.bin is missing, cannot start
halt: Unable to iterate IDE devices: No such file or directory
[TIMESTAMP] System halted.

The message about the missing IDE devices seems to be there without my
WiFi controller as well, without any ill effects on sutdown. Seems my
IDE disk is called sda, and halt might expect hda. "wlan" is the name
given to my WiFi controller by modifying the persistent udev rules.

The part about atmel_at76c502_3com.bin is really strange indeed. I have
/lib/firmware/2.6.24-17-generic/atmel_at76c502_3com.bin from linux-
ubuntu-modules-2.6.24-17-generic which matches my current kernel, and
recently also installed atmel-firmware which gave me
/lib/firmware/atmel_at76c502_3com.bin. So the file should be present and
available. A "cannot start" message at shutdown seems very strange, and
taking so much time to figure out that file doesn't exist would be
warranted only for a complete filesystem scan.

Maybe the fact that my root fs is on lvm2 has something to do with this,
as my volume might have already been stopped during the shutdown
process. I don't really think so, as that would probably cause problems
with the shutdown, e.g. prevent the process listing I have hacked into
the halt script just before the message.

When I'm not patient enough to wait for this kind of shutdown, I tend to
play around with the Magic SysReq Key. Sync won't work right away; it
would start an emergency sync but not complete it. Sending SIGTERM to
all processes causes init to complain that rc0 died, but afterwards, I
can use the SysReq key to sync, mount readonly, and power down. So it
seems that NetworkManager is responsive to SIGTERM here, where on the
other hand it seemed to survive the "Sending all processes the KILL
signal" from sendsigs. Strange indeed.

As for how to reproduce this, I often used this minimal boot process:
1. Boot in recovery mode
2. Drop to root console
3. /etc/init.d/dbus start # needed by hal
4. /etc/init.d/dhcddb start # as I once got swamped by NetworkManager messages 
without this
5. /etc/init.d/hal start # in order to tell nm about the pc card, I guess
6. halt

[Bug 235930] [NEW] rpc.idmapd needs nfsd.ko

2008-05-29 Thread Martin von Gagern
Public bug reported:

After starting nfs-common with NEED_IDMAPD=yes, I tried to mount an
NFSv4 mount. The mount worked, but the ownerships were mapped to
nobody/nogroup. I verified rpc.idmapd was running on both ends, which
was the case. Next I killed rpc.idmapd and restarted it from the command
line with debug output: "rpc.idmapd -fvvv". The result on the ubuntu
side was pretty instructive:

$ sudo rpc.idmapd -fvvv
rpc.idmapd: libnfsidmap: using domain: localdomain

rpc.idmapd: libnfsidmap: using translation method: nsswitch

rpc.idmapd: Expiration time is 600 seconds.
rpc.idmapd: nfsdopenone: Opening /proc/net/rpc/nfs4.nametoid/channel failed: 
errno 2 (No such file or directory)

Indeed there was no directory nfs4.nametoid in /proc/net/rpc. As the
/proc structure is generated by the kernel, I grepped the nfs kernel
sources and found a reference in fs/nfsd/nfs4idmap.c. This is the nfs
SERVER module! After modprobing that, I got the required directory, got
idmapd to start without complaint, and got my mount with correct user
mapping.

So it seems that even an NFSv4 client would need nfsd.ko loaded. More
precisely, idmapd needs it, so /etc/init.d/nfs-common should modprobe it
whenever it hat NEED_IDMAPD=yes.

[Bug 106401] Re: idmapping with nfs4 mounts not working in feisty

2008-05-29 Thread Martin von Gagern
Same problem with correct mapping for file listings but denied write
access here in hardy, after avoiding bug #235930, which by the way might
be useful for people who get "nobody,nogroup" mappings.

Running "rpc.idmapd -fvvv" on both machines showed me that id mapping
was done from server numeric ids to names to client numeric ids, but
apparently not the other way round. I haven't understood nfs4 enough to
judge whether or not this is expected behaviour. I guess I'd need to
read more of rfc 3530, as I can't fathom yet where in my wiresharked
network traffic all this user authentication is supposed to happen.

[Bug 106401] Re: idmapping with nfs4 mounts not working in feisty

2008-05-30 Thread Martin von Gagern
On my net the same users have different numeric IDs on different machines. 
While id mapping takes care of this for the file ownership attribute, it won't 
work for user authentication for sec=sys mounted systems as I had hoped. So 
even though the files get displayed with correct user names on both ends, the 
server may think you a different person, most probably "nobody". I found out 
about this in mail archives:
http://thread.gmane.org/gmane.linux.nfsv4/466
http://thread.gmane.org/gmane.linux.nfsv4/7103/focus=7105

On the whole, this issue seems to be a whishlist item for NFS (v5?), but
not an actual bug in Ubuntu. I have to say that the complete lack of a
comprehensive error message makes it quite difficult to understand,
though.

[Bug 235899] Re: 3Com 3CRSHPW_96 (atmel) defers halt

2008-08-22 Thread Martin von Gagern
Seems to be still present in in the linux kernel packages from Intrepid:
still takes ages to shut down.

I don't yet feel like doing a full upgrade, as this is a production
system which I need in functional state. Just trying to upgrade the
header has caused me quite a lot of trouble as it is, as I'm using an
nvidia graphics card, and building the modules for these seems to
involve quite a lot of dependencies, inclusing glibc. So I'll only do a
full upgrade to Intrepid probably somewhere around Alpha 6 or Beta.

I'll try to give you the information mentioned above. I first wanted to
get nvidia functioning again, and failing to do so I downgraded to Hardy
and forgot to save these files before. I'll upgrade the kernel again
later on if I find the time.

[Bug 261380] Re: Packages have invalid .gnu_debuglink

2008-12-31 Thread Martin von Gagern
I've got a proposed version in my PPA, with debug packages managed by dh_strip, 
not the qt build process.
See https://launchpad.net/~gagern/+archive

Adding CONFIG+=nostrip to QMAKE_VARS in the configure script didn't
work, so I added it to some other spec file. I also found that cdbs
provides elaborate support for debug packages, and made use of that. The
resulting list of debug symbol files looks somewhat longer, needs to be
invedtigated still.

I'll attach the patch to stop the build from stripping its binaries as
well as a patch of the rules file later on; the system where I developed
this is already down. Until then, you can compare my diff or simply use
my version.

[Bug 320590] [NEW] undefined symbol: Py_InitModule4

2009-01-23 Thread Martin von Gagern
Public bug reported:

Binary package hint: python-clearsilver

python-clearsilver 0.10.4-1ubuntu1 from ubuntu hardy fails to load with
python 2.5.2:

$ python --version
Python 2.5.2

Traceback (most recent call last):
  File "", line 1, in 
ImportError: /usr/lib/python2.5/site-packages/neo_cgi.so: undefined symbol: 
Py_InitModule4

This might be due to the fact that the same library is installed for
python 2.4 and python 2.5, at least here on the amd64 architecture:

$ md5sum /usr/lib/python2.*/site-packages/neo_cgi.so

On intrepid i386 with clearsilver 0.10.4-1.3, the module loads, and the files 
are different.

[Bug 66696] Re: orinoco_cs doesn't support WPA

2008-12-18 Thread Martin von Gagern
Some updates:
1. The standalone orinoco driver does not compile against the 2.6.27.9 headers, 
they are too old.
2. The patches by David Kilroy were merged into Linus' linux-2.6.git so I'd 
expect them in linux 2.6.28
3. The corresponding files grabbed from the git don't compile against 2.6.27.9 
either, 2.6.28 has diverged too far
4. I managed to identify a bunch of relevant changesets and apply them to the 
2.6.27.9 sources
The result should become available at https://launchpad.net/~gagern/+archive in 
the near future. I haven't given it any testing at all so far, and won't have 
the time to do so today. Those anxious to see this can give it a try, otherwise 
I'll get back here once the build is done, I've tested installing the package 
and using the module.

[Bug 66696] Re: orinoco_cs doesn't support WPA

2008-12-20 Thread Martin von Gagern
OK, the orinoco dkms package in my PPA does compile all right, and gets
loaded after reboot. It also loads a firmware file if I copy it to
/lib/firmware/agere_sta_fw.bin. So far the package does not include such
a firmware file, in order to avoid possible collisions with future
Ubuntu packages. You have to copy the firmware yourself for now.

So much for the good news. The bad news is that with the agere firmware
I pointed out above my card still fails to establish WPA connections.
Lots of messages in dmesg, most about dropped info frames or some such,
which I take as an indication that this firmware is not for the hardware
I have, some old Toshiba Mini-PCI card. I also couldn't find a Windows
driver capable of WPA for this card, so using the agere_fw_utils to
extract the firmware from windows drivers isn't an option either, and it
might be the hardware can't support WPA with any firmware.

So I can't give you an answer as to if this driver would enable WPA on
orinoco_cs cards, given the correct firmware. Please try this yourself,
see if it works for you or not, especially if you have WPA working on
Windows.

It looks like David Kilroy is doing some work for WPA-enabled orinoco drivers. 
See these references:
Patch series intro:

It would be nice to get the standalone version of the orinoco drivers
(which includes these patches) together with the necessary tools and
firmware files bundled in some DKMS-enabled ubuntu package and uploaded
to some PPA. I might give this a try when I find the time, but I'm no
debian packaging guru, so I wouldn't expect too much.

[Bug 261380] Re: Packages have invalid .gnu_debuglink

2009-03-16 Thread Martin von Gagern
Do I understand you correctly that the diff in my PPA is enough for now, 
rendering Marco's request for a patch obsolete?
So now I wait for some sponsor to have a look at this, and work out the next 
steps based on his opinion?
The version against which my patch was created is no longer current. Should I 
create a new patch, and if so, against Jaunty, Intrepid, or both?

[Bug 261380] Re: Packages have invalid .gnu_debuglink

2009-03-16 Thread Martin von Gagern
> The resulting list of debug symbol files looks somewhat longer, needs
to be invedtigated still.

I've investigated this now. The original debug packages only contained
debug symbols for libraries. With my patch in place, it contains debug
symbols for binaries as well. Debug files for the following additional
files end up in my libqt4-dbg:

1 from libqt4-dbus: /usr/bin/qdbus
1 from qt4-designer: /usr/bin/designer-qt4
1 from qt4-qtconfig: /usr/bin/qtconfig-qt4
9 from qt4-dev-tools: assistant-qt4 assistant_adp linguist-qt4 pixeltool 
qcollectiongenerator qdbusviewer qhelpconverter qhelpgenerator xmlpatterns
10 from libqt4-dev:  lrelease-qt4 lupdate-qt4 moc-qt4 qdbuscpp2xml qdbusxml2cpp 
qmake-qt4 qt3to4 rcc uic-qt4 uic3
217 from qt4-demos: qtdemo, 5 libs from /usr/lib/qt4/plugins/designer, 15 demos 
and 196 examples

It would seem to me that for the former, the libqt4-dbg package is a
suitable place, even if they amount to something like 63MiB unpacked
space on the system.

The number of files corresponding to the demos package is excessively
large, though, and they consume around 145MiB unpacked. I suggest to
either start a separate package qt4-demos-dbg for those, or dropping
debug info for them altogether. While the use of those demos to the
common qt user is probably pretty small, those actually using the
package are developers and thus likely to be interested in debugging
them as well. Therefore I'd opt for one more debug package to be built
from the qt4-x11 source package.

I'll create an updated patch for this.

I created an updated patch for Jaunty. It failed to build on my PPA,
though, due to some PostgreSQL-related issue that seems unrelated to my
patch, but makes testing a bit difficult. I'll try a local build
tomorrow, I think. The attached patch introduces three new debug
packages, for qt4-dev-tools and libqt4-dev as well as qt4-demos, in
order to reduce the size of installed debug files for each of these

[Bug 261380] Re: Packages have invalid .gnu_debuglink

2009-03-18 Thread Martin von Gagern
It took me a while to find the relevant documentation about pkg-create-dbgsym:
https://launchpad.net/pkg-create-dbgsym
https://wiki.ubuntu.com/AptElfDebugSymbols
https://launchpad.net/ubuntu/+spec/apt-get-debug-symbols

If this is really the way to go, some reference in
https://wiki.ubuntu.com/PackagingGuide would be useful.

I'm not an experienced Ubuntu/Debian packager, but here is my impression
comparing those two solutions:

1. My patch, using cdbs and old -dbg packages
- additional -dbg packages added to control
- debug symbols from multiple binary packages can be collected in one debug 
package
- easy to build on ppa and install locally using apt-get

2. Your suggested method, using pkg-create-dbgsym and new ddeb packages
- all -dbg packages removed from control
- exact 1:1 corresponcence between binary packages and debug packages
- don't know how to install those packages locally, nor how ppa deals with them

As https://wiki.ubuntu.com/AptElfDebugSymbols#apt%20changes regarding
installation of debug symbols doesn't seem implemented yet, at least not
on my intrepid, I'm not convinced that this approach is ready to replace
the old -dbg packages yet. I still created a corresponding patch.

About lintian: I haven't understood the functioning of lintian yet, nor
the reason for those overrides in the old package. My renames were
simply intended to have as little impact on current behaviour as
possible. I'd be happy to drop them. If we drop the -dbg packages, the
corresponding lintian files have to go in any case.

OK, yet another debdiff. Revertet to -dbg packages (including a few

[Bug 328980] Re: xkbcomp errors should be displayed

2009-03-05 Thread Martin von Gagern
> could you describe a way to trigger the error?

I hit this in bug #327963. So a way to reproduce is this:
1. set keyboard layout to "Germany Macintosh, no dead keys"
2. set keyboard model to "MacBook / MacBook Pro (Intl)"

This might only work until someone fixes #327963, though. After that,
you might have to revert their change or introduce some artificial
problem with the xkeyboard-config data. Or use some unfixed aspect of
bug #67188.

> do you get that at the session start or when using the capplet?

Both. When using gnome-keyboard-properties it happens, and when leaving
the broken settings, it happens again at session start.

[Bug 328980] [NEW] Pass error messages from xkbcomp to Gnome user

2009-02-13 Thread Martin von Gagern
Public bug reported:

Binary package hint: gnome-settings-daemon

When the user runs gnome-keyboard-properties and some of his settings
cause xkbcomp to fail, the user gets a general error message about
"Error activating XKB configuration" and some obscure hints as to where
the cause might lie. The same holds for starting a Gnome session with a
broken configuration. This leads to little information available in bugs
like the often-duped bug #67188.

Instead, I would like to see the precise error message from xkbcomp
displayed to the user. At least in my original bug #327963, the
information provided there was much more useful to actually locate and
solve the problem.

I guess fixing this problem might include several packages. gnome-
settings-daemon is where the current error dialog is generated, but the
actual call to xkbcomp seems to be in libxklavier, with libgnomekbd in
between. I'll try to mark this bug as affecting all these packages.

[Bug 327963] Re: Error activating XKB configuration with MacBook keyboard model

2009-02-13 Thread Martin von Gagern
> Getting a better error message for the Gnome UI is a GNOME issue
obviously, not xkeyboard-config's duty, and really ought to be filed
separately against the appropriate GNOME component.

I agree, just filed bug #328980 for this. It's a bit tricky, as it
involves multiple packages.

> As to the secondary bug of the error activating XKB, that's a well
known issue so will dupe to that. Undupe (and clarify) if you'd like
something differently done.

I had bug #67188 considered before filing mine, but the mention of
editing xorg.conf in the headline didn't seem to apply to me at all, so
I filed a new one. Now that I've read all the comments in #67188, I get
the feeling that it is a large collection of bugs with quite different
reasons, but all looking the same due to missing error messages. Some,
like bug #67188 comment #38, are the same as this one here, while others
have different causes, for which I don't know the reason. For lack of
information, I expect #67188 to remain open for quite a long time.

In contrast to this, the scope of what I request for here is much clearer, and 
a fix is possible. Therefore I'd undupe and ask that you
 1. make macintosh_vndr/de(mac_nodeadkeys) an alias for 
macintosh_vndr/de(nodeadkeys)
 2. Do the same for the deadkeys variant
 3. Do the same for languages other than "de" with similar configuration
The attached patch tries to follow this approach. I grepped fro '"mac' in 
symbols/* and then made sure the same variants were included as aliases in 
symbols/macintosh_vndr/*. Not tested yet.

You might, on the other hand, be of the opinion that having different
names for the same symbols is not the way to go, and that instead of
providing these aliases at the xkb-data level, the user interface should
prevent the user from selecting such combinations. In that case, another
bug for the Gnome control-center would be in order, while you might mark
this as invalid for xkeyboard-config.

[Bug 67188] Re: "Error activating XKB configuration." - Requires manual xorg.conf editing

2009-02-13 Thread Martin von Gagern
I have the feeling that this bug here might be a collection of several
distinct issues, which all look the same due to lack of precise error
messages. I filed bug #328980 asking for error messages to be displayed
to the user.

Until then, you might use the attached script to learn more about this
kind of error. Download it, and then call "sudo bash
DownloadedScriptName install" in order to install a wrapper around
xkbcomp. Then reproduce the issue, and have a look at /tmp/xkb.*/* for
more details about xkbcomp invocations, especially /tmp/xkb.*/err for
standard error messages. Once you are done, you can invoke the script
with "sudo bash DownloadedScriptName uninstall" to remove the wrapper
and "sudo bash DownloadedScriptName clean" to delete the collected data.

With such a wrapper, you can get additional information, like shown in
bug #327963 for my own Mac-related issue. Maybe with this information it
becomes possible to distinguish the different causes of xkb error
messages, and address them appropriately.

[Bug 328980] Re: Pass error messages from xkbcomp to Gnome user

2009-02-13 Thread Martin von Gagern
I just confirmed that the stderr of the xkbcomp invocation is redirected
to /dev/null, so error messages are indeed completely lost.

A fist step towards sensible error messages would probably be to
redirect stderr in libxklavier in such a way that it can be directed
into the syslog. This would involve no change to interfaces or other
packages, and while being far from optimal, would give users a realistic
chance to see their error messages.

Once we have the message available in the current process, and sent to
syslog, we could augment the interfaces to pass the message up to gnome-
settings-daemon and incorporate it into the error message.

[Bug 327963] [NEW] Error activating XKB configuration with MacBook keyboard model

2009-02-11 Thread Martin von Gagern
Public bug reported:

Binary package hint: xkb-data

I've got Intrepid installed on a MacBookPro5,1 with German keyboard
layout. I started configuring the keyboads using gnome-keyboard-
properties as available from the settings menu. I first selected the
layout "Germany Macintosh, eliminate dead keys" and followed that up
with changing the model to "MacBook/MacBook Pro (Intl)". This resulted
in an error message "Error activating XKB configuration" which asked me
to prvide this additional information:

$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "de", "mac_nodeadkeys", ""
_XKB_RULES_NAMES(STRING) = "evdev", "pc105", "de", "mac_nodeadkeys", ""

$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = []
 model = macbook79
 options = []

As the error message from the dialog contains little actual information,
I straced gnome-settings-daemon and identified a failing invocation of
xkbcomp as the likely cause of the issue. By renaming /usr/bin/xkbcomp
and replacing it with a wrapper script, I managed to get my hands on its
input file and reproduce the issue:

$ cat /tmp/fileJPMGgA 
xkb_keymap {
xkb_keycodes  { include "evdev+aliases(qwertz)" };
xkb_types { include "complete+numpad(mac)" };
xkb_compat{ include "complete" };
xkb_symbols   { include 
"pc+macintosh_vndr/de(mac_nodeadkeys)+inet(evdev)" };
xkb_geometry  { include "macintosh(macbook79)" };
};

$ xkbcomp -I -I/usr/share/X11/xkb -xkm /tmp/fileJPMGgA /tmp/fileNtKqh7
Error:No Symbols named "mac_nodeadkeys" in the include file 
"macintosh_vndr/de"
  Exiting
  Abandoning symbols file "(null)"

That looks like a much better error description. Looking at
/usr/share/X11/xkb/symbols/macintosh_vndr/de I see that indeed it
doesn't contain a description of "mac_nodeadkeys". Neither does it
include /usr/share/X11/xkb/symbols/de where the mac_nodeadkeys would
have been defined. Changing the layout to simple "Germany Eliminate dead
keys", I could use the MacBook keyboard model all right, just as
mac_nodeadkeys layout worked all right with a Generic keyboard model.
However, both combinations don't fully match the key labels.

My first concern is that for an obvious choice like a MacBook keyboard
model with a mac keyboard layout, no obscure error messages should be
generated by the Gnome UI. Secondly, it would be nice to actually get
Mac keyboard layout, in order to stay consistent with OS X and friends.

> both combinations don't fully match the key labels.

I guess I'll take that back. Having the left Alt key perform as AltGr as
it does in Mac OS X doesn't seem to make too much sense, as many
applications expect the existence of an Alt/Meta key to invoke commands.
The right Alt key works as AltGr and allows access to all those special
symbols in the same location where OS X has them. Therefore, simply
extending the definition to make macintosh_vndr/de(mac_nodeadkeys) an
alias for macintosh_vndr/de(nodeadkeys) might be enough to avoid the
error and yield reasonable results. That should be easy.

[Bug 263596] [NEW] linux-restricted-modules postrm script dies for removed kernel

2008-09-01 Thread Martin von Gagern
Public bug reported:

Binary package hint: linux-restricted-modules-2.6.26-5-generic

Investigating a different bug, I installed the latest intrepid kernel
packages on a hardy system. After that, I tried to remove a previous
intrepid kernel version. I'll attach a verbose log of the commands I
used and the output they generated. The core of the problem is this
error message:

Removing linux-restricted-modules-2.6.26-5-generic ...
FATAL: Could not open '/boot/System.map-2.6.26-5-generic': No such file or 
directory

Errors were encountered while processing:
 linux-restricted-modules-2.6.26-5-generic
E: Sub-process /usr/bin/dpkg returned an error code (1)

The script /var/lib/dpkg/info/linux-restricted-
modules-2.6.26-5-generic.postrm seems to return an error code of 1
because it calls both depmod and update-initramfs unconditionally, and
returns the exit code of the last command called as its own exit code.
depmod and update-initramfs fail because the kernel package has already
been uninstalled at that time.

A quick and dirty fix is to append the command "true" to the list of
commands executet during removal. This will cause the script never to
fail, regardless of previous errors. If on the other hand you want to
provide more elaborate error handling, then the exit status of depmod
should be checked as well, and both should be skipped if the
corresponding kernel package is no longer available.

This patch appends true to the script, so that it's exit code is always

allows package removal even after the kernel has been removed, although

[Bug 115426] Re: Computer name is not recognized by DHCP of FRITZ!Box

2008-06-12 Thread Martin von Gagern
Officially, the client identifier should be staring with 1 if you follow
it up with the mac address, like "1:YO:UR:_M:AC:AD:DR". That's because
dhcp3 treats the whole thing as an opaque byte sequence, whereas
http://tools.ietf.org/html/rfc2132#section-9.14 says the first byte
should state what kind of identifier is used, with 1 for Ethernet MAC
addresses according to http://www.iana.org/assignments/arp-parameters
parameter "Hardware Type (hrd)". You may also use 0 followed by any
arbitrary byte sequence you want. I think this should work:

send dhcp-client-identifier "\0My identifier name"

although I don't have my Ubuntu running right now to test it.

I'd also consider all this a kind of bug in the Fritz!Box, as it should
in my opinion derive a client identifier from the sender's mac address
if none was specified, and assign a host name in any case.

I wrote a message to AVM about it on 2008-05-23 using the web form
http://www.avm.de/de/Service/Service-Portale/Service-
Portal/Ihre_Meinung/Feedback.php?portal=FRITZ!Box_Fon_WLAN_7170 and my
message was forwarded to the tech guys on 2008-05-26. As improvement
requests don't seem to get a ticket at AVM, that information is all I
have to track it, but if you want to write them as well, mentioning
those references might help them realize it's the same issue and avoid
redundant work.

[Bug 336401] Re: Xorg crashed with SIGSEGV in ActivateDevice() - wacom tablet

2009-04-17 Thread Martin von Gagern
Same here, after freshly upgrading from Intrepid to Jaunty RC, running
natively on hardware (no VM), wacom tablet configured in xorg.conf, but
not plugged in. Access via ssh possible. Reproducable.

Xorg.0.log contains those same lines as in the attached XorgLogOld.txt, except 
for minor address offsets:
Backtrace:
0: /usr/bin/X(xorg_backtrace+0x3b) [0x813518b]
1: /usr/bin/X(xf86SigHandler+0x55) [0x80c7be5]
2: [0xb7f2b400]
3: /usr/bin/X(ActivateDevice+0x4f) [0x808662f]
4: /usr/bin/X(InitAndStartDevices+0x42) [0x8086732]
5: /usr/bin/X(main+0x36f) [0x807229f]
6: /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7af7775]
7: /usr/bin/X [0x80717a1]
Saw signal 11.  Server aborting.

I recompiled the wacom package with DEB_BUILD_OPTIONS="nostrip noopt debug" and 
ran it through gdb:
#0  0xb6c11aa0 in xf86WcmDevProc (pWcm=0x9949658, what=0)
at ../../../src/xdrv/xf86Wacom.c:1014
#1  0x0808662f in ActivateDevice ()
#2  0x08086732 in InitAndStartDevices ()
#3  0x0807229f in main ()

The section in question:
1009 static int xf86WcmDevProc(DeviceIntPtr pWcm, int what)
1010 {
1011LocalDevicePtr local = (LocalDevicePtr)pWcm->public.devicePrivate;
1012WacomDevicePtr priv = (WacomDevicePtr)PRIVATE(pWcm);
1013
1014DBG(2, priv->debugLevel, ErrorF("BEGIN xf86WcmProc dev=%p priv=%p "

DBG expands like this:
#define DBG(lvl, dLevel, f) do { if ((lvl) <= dLevel) f; } while (0)

The error occurs when priv->debugLevel gets loaded in order to evaluate the if. 
gdb confirms this:
(gdb) print priv->debugLevel
Cannot access memory at address 0x72657369

So the cause of the problem is that xf86WcmDevProc thinks this private
data should be a pointer to some valid wacom-specific data, which is not
the case. PRIVATE is an alias for XI_PRIVATE from
/usr/include/xorg/xf86Xinput.h.

I'll try to recompile xorg-server. Sometimes debugging would be so much
easier if I could simply grab those debug symbols via apt-get!!!

Bug 357544 is probably the same, and came to the same (intermediate) conclusion.
Bug 361972 is probably the same as well.

[Bug 399244] [NEW] php-openid 2.0.0 has broken support for HMAC-SHA256

2009-07-14 Thread Martin von Gagern
Public bug reported:

Binary package hint: php-openid

php-openid-2.0.0 does not correctly deal with associations of type HMAC-
SHA256. The code only supports the generation of HMAC-SHA1 signatures,
but it fails to reject attempts at a HMAC-SHA256 connection with an
"unsupported-type" error code as http://openid.net/specs/openid-
authentication-2_0.html#refuse_assoc requires. The result is that a php-
openid-2.0.0 server on current stable (jaunty) or current LTS (hardy)
will be considered invalid by e.g. a current ZendFramework client like
the one employed by sourceforge.

This bug here might be contributing to bug #313703, although there might
be more in that bug. The solution is probably the same, though: updating
to 2.1.3 as available in karmic. It shouldn't be too difficult to
backport this package to hardy and jaunty, and maybe to intrepid as
well. Maybe the package from karmic can be taken as is.
