[Desktop-packages] [Bug 2023355] [NEW] python-doc search does not work
Public bug reported: The search interface to locally installed python-3.10-doc (and probably other versions) fails to work in Firefox. To reproduce, attempt to search from this page (or the search bar on other pages): file:///usr/share/doc/python3.10/html/search.html The reason for this is the jquery.js and underscore.js files are symlinks to files under /usr/share/javascript/, and Firefox won't follow them. Replacing the symlinks with copies fixes the problem, in the short term at least. This could presumably be fixed in the python packages by removing the parts of debian/rules that make these into symlinks in the first place. Having a locally searchable copy of the documentation is useful when there is no network. ** Affects: firefox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/2023355 Title: python-doc search does not work Status in firefox package in Ubuntu: New Bug description: The search interface to locally installed python-3.10-doc (and probably other versions) fails to work in Firefox.

[Desktop-packages] [Bug 1471029] Re: ELF programs with R_386_RELATIVE blocks are badly mapped into memory
hi Colin, I first met on a 3.19.0-20 build: Linux samba-build-i386-32bit 3.19.0-20-generic #20-Ubuntu SMP Fri May 29 10:06:53 UTC 2015 i686 i686 i686 GNU/Linux and as far as I can tell (taking into account Joseph's 3.16 and upstream 4.2rc3), that a87938b/b51621a commit is neither the cure or culprit. It is interesting that it works for you on a VM -- it looks like the specific VM peculiarities matter.

Thanks Joseph!
It's no better with 3.16.0-44-generic #59~lp1471029. Perhaps even slightly
worse -- in my sample of 2 I've seen the heap at b8d- and b94-, while I think
stock Vivid 3.19 was most often in the b7's.

[Desktop-packages] [Bug 1471029] Re: ELF programs with R_386_RELATIVE blocks are badly mapped into memory
So, it isn't the ld-linux.so, it is the kernel on 32 bit i386, where exec is loading PIE elf binaries in such a way that the heap and the stack are next to each other and have very little room. About 20% of /usr/bin/* (and others, like /bin/systemd) on the vivid cloud image is affected, though in many cases their memory use is too low to cause problems. The problem was discovered in the samba test suite, which uses xsltproc to generate manpages. One of the bigger man pages caused a segfault. ** Package changed: glibc (Ubuntu) = linux (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libxslt in Ubuntu. https://bugs.launchpad.net/bugs/1471029 Title: ELF programs with R_386_RELATIVE blocks are badly mapped into memory Status in libxslt package in Ubuntu: Triaged Status in linux package in Ubuntu: New Bug description: Running the Samba autobuild tests on a 15.04 openstack image results in a segfault in this command: /usr/bin/xsltproc --nonet -o default/docs-xml/manpages/smb.conf.5 /home/ubuntu/autobuild/b22271/samba/docs-xml/xslt/man.xsl default /docs-xml/manpages/smb.conf.5.xml I reported this upstream as a bug in xsltproc, but it was found to be impossible to reproduce using upstream source on the openstack instance: https://bugzilla.gnome.org/show_bug.cgi?id=751764 Comment 8 (https://bugzilla.gnome.org/show_bug.cgi?id=751764#c8) is particularly informative.

[Desktop-packages] [Bug 1471029] Re: Segfault in xsltproc on i386
This is a dynamic linking/loading problem, not related to libxml2 (or xsltproc) as first thought. The problem seems to be that executables with R_386_RELATIVE components are being mapped entirely (including the heap) into memory between roughly B700 and BFFF, which gives them roughly 140M to work with. Most programs can cope with that, but some (e.g. xsltproc performing described task) cannot. I don't know whether to blame ld-linux.so or the kernel.

[Desktop-packages] [Bug 1471029] Re: Segfault in xsltproc on i386
I tried some more things: 1. Compiling with clang makes no difference. 2. Compiling with -fsanitize=address results a stack overflow message followed by a stack trace. It doesn't reveal as much as the post-mortum traceback in gdb. The address sanitizer seems to make the error deterministic. 3. Copying the debian/ packaging directory into the git tree and compiling from there makes no difference. Most of the contents of debian/patches are already upstream anyway. 4. Switching the linker to gold makes no difference. The process map (from apport-unpack) never lists memory as [stack], and always has a double [heap] listing with a window of 0x1000 in the middle. Like this: dump9/ProcMaps:b7ccf000-bfabb000 rw-p 00:00 0 [heap] dump9/ProcMaps:bfabc000-bfb14000 rw-p 00:00 0 [heap] The stack pointer is using the second of these (i.e., in this case bfabc000-bfb14000, and the segfault is when it hits the window. Typically this allows the stack a few hundred kB (352k in the example above). It looks like something is putting the process's memory together wrongly. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libxml2 in Ubuntu. https://bugs.launchpad.net/bugs/1471029 Title: Segfault in xsltproc on i386 Status in libxml2 package in Ubuntu: New Bug description: Running the Samba autobuild tests on a 15.04 openstack image results in a segfault in this command: /usr/bin/xsltproc --nonet -o default/docs-xml/manpages/smb.conf.5 /home/ubuntu/autobuild/b22271/samba/docs-xml/xslt/man.xsl default /docs-xml/manpages/smb.conf.5.xml I reported this upstream as a bug in xsltproc, but it was found to be impossible to reproduce using upstream source on the openstack instance: https://bugzilla.gnome.org/show_bug.cgi?id=751764 Comment 8 (https://bugzilla.gnome.org/show_bug.cgi?id=751764#c8) is particularly informative.

[Desktop-packages] [Bug 501601] Re: Bash in gnome-terminal shows control characters as unsupported-unicode squares
The annoying thing for me is not that these characters are represented, but that they ignore the character grid. If I run, for x in `seq 1 31`;do echo -e $x-\\x$(printf %x $x)=;done it should print the character code, followed by a minus, followed by a representation of the character code, followed by an equals sign -- except when the character code tells the cursor to jump around or delete stuff. On the linux console, and in plain old xterm, the non-moving characters print are invisible and take up no space. In xfce4-terminal, they print as little squares but stay within their assigned box. In gnome terminal, as in the attached picture, they encroach over the following character, so that you can't read it. This is annoying, because it means you can't look at files that e.g. use the field separator codes (28-31) as field separators. ** Attachment added: Image showing many control characters misbehaving https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/501601/+attachment/4134902/+files/gnome-terminal.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/501601 Title: Bash in gnome-terminal shows control characters as unsupported-unicode squares Status in “gnome-terminal” package in Ubuntu: Incomplete Bug description: Binary package hint: gnome-terminal When I upgraded to Karmic (clean install) I noticed bash echoes control characters using the hat notation (ex. ctrl+c shows as ^C). stty reported echoctl being set, so I tried to unset it. This helped, and pressing ctrl+c at a prompt cancels the prompt, shows a new one and nothing is echoed. Though, when pressing ctrl+c while a program is running (ex. cat or ping), a unicode square is echoed like for unicode characters not supported by the selected font. I tried selecting many different encodings and fonts, though nothing seemed to help. Futher, if inside this same shell I open a screen session, this behaviour is gone and everything works as intended, which is to have ctrl+c or ctrl+z have the desired effect with nothing echoed. Finally, opening a bash session in xterm or tty[1-6] and disabling echoctl/ctrlecho using stty command, this cannot be reproduced. So it seems that only an plain bash session in gnome-terminal does this. To see a screenshot, view the attached PNG. Basically what happens there is 1. 2 ctrl+c presses at the prompt. 2. Then 1 ctrl+c during cat 3. Then 1 ctrl+z during cat 4. Bring cat back to the foreground and press ctrl+c again THEN disable echoctl 5. Repeat the process - where you can now see instead of hat notation, the prompt presses are fine, but the in-program presses echo unicode squares. Very frustrating.
