Bug Description

Binary package hint: acroread

In Konsole (sorry for error logs length, I'm not able to sort these repetitive lines) :

Same here. Also 10.04, 64 bits.

When I open a PDF, npviewer.bin is launched, and npviewer.bin launches acroread.

Then, if I go back (pressing Back on Firefox), acroread rests as a zombie proccess, while npviewer is still waiting.

When that happens, the links to PDF files won't work anymore unless I kill the npviewer.bin process, in which case the links will work again until acroread gets zombie again.

As a workaround, press Alt+f2 and input "killall npviewer.bin". This still needs to be fixed.

Sorry by double posting, but can anyone with appropriate permissions to change the bug topic? The errors are not the issue. The issue here is that PDFs are not displayed properly due to a npviewer.bin and acroread miscommunication. Thanks.

Here are a couple of really ugly workarounds if like me you have to have embedded PDFs in FireFox.

1 add an application launcher to the panel with the code killall npviewer.bin
click on it when acroread freezes up and then refresh your page

2 switch to the 32 bit version of Ubuntu

3 Remove RAM to 3GB or under (this working indicates that nswrapper is not working properly)

I know none of these are great options but as this is a closed source project we will have to wait for Adobe to fix acroread and that might be a while.

All patched up to the latest version this morning.

It was introduced by acroread 9.4.2, the 9.4.1 version was OK.

I installed acroread 9.4.1 from the archive, it has the same problem only it happens less often then with version 9.4.2
If I install version 9.4.1 the problem can be "solved" be stopping and starting the browser again, it cleans up the defunct acroread process.

Still broken in 9.4.6. The issue described in the release notes sounds like a browser freeze, whereas this issue is where acroread exits, but nspluginwrapper/nppdf.so is still around so it prevents future PDFs from being viewed.

This is not a mozilla bug, as far as I can see. It rather appears to be Adobe's fault. Anyway, I had the same problem and, since I could not find a solution in the web, I wrote a small workaround program.

You'll find some hint on what's under the hood in the comment at the beginning of the file acroread_interceptor.c
Hope it will help you.

You have to compile the source files; you can use the script
build_interceptor.sh to do so.
When done, please move (or copy) the files "acroread_interceptor" and
"acroread_exec_monitor.so" in /usr/local/bin.
(optionally, you can change this path at will by editing the .c source file
and recompiling, I'll asume you're using this one)
Once you've done this, you can try if it works for you by executing

$ export LD_PRELOAD=/usr/local/bin/acroread_exec_monitor.so
$ firefox

(be sure to close all firefox windows first)
Open a PDF file, then close that tab, wait >30secs and try again.
You should find two acroread processes, the parent one being my interceptor.
If it works, you can then install it permanently the way you prefer: I
suggest putting the following line:

export LD_PRELOAD=/usr/local/bin/ acroread_exec_monitor.so
---------------------------------------------------------------------------------------------------------
in a file executed at logon (your .bashrc, or a script in /etc/profile.d/
if you can become root).
This way, you can automatically keep using the workaround after acrobat
upgrades (I don't think they'll fix it
soon, since I discovered this bug is around since a while).

Finally, I send you the latest version of the program I wrote, because I
fixed a missing check and changed the hardcoded path of "/home/senato" into
"/usr/local/bin".

Feel free to examine and modify it (some knowledge of C will help).
Let me know, I'll be glad to help.

Yes, the LD_PRELOAD has to point to the file.
The messages you get are just debugging hints that could help in case of
problems, you can get rid of them
either by suppressing the code that generates them in the program and then
recompiling and reinstalling, or
by error redirection.
The write errors are symptoms of one of the reasons of Adobe original
plugin's misbehavior.
The "cannot understand..." message is just wrong, a non-impacting error I
fixed in the last release I posted
earlier today in the board. This last version is also easier to install and
manage.
Happy to know it helped you.

Please use the lastest version (you'll find it in the attachement),
following the instructions in the INSTALL file.
Use the file "run_firefox.sh" to run firefox. If it works (and it should),
you can remove the "export ..." line from your bashrc file.
This version also fixes a problem that would have prevented acrobat reader
from working if launched as a standalone program.

Massimiliano Calandrelli (massimiliano-calandrelli) wrote :

The short answer is: yes.

Alternatively, you can insert the (eventually edited) "export" lines into
the appropriate files, so that the GUI runs with an environment in which
the LD_PRELOAD variable is correctly set.
Clicking on an icon to launch firefox should then have the same effect of
using the sample "run_firefox.sh" script.
At the same time, the Acrobat reader icon should work (but only if you
replaced the executables with the ones obtained by compilation of the last
version of source code; previous versions of my program did not correctly
handle the standalone reader).

Kernel changes should not affect the workaround code; however, changes in
Acrobat Reader's version and/or in the desktop manager you use, could do
so..

No, unless you have installed the files in different locations, you don't
need to export the other two variables; of course, being explicit wouldn't
hurt.
Check for correct file permissions and double check that extra space I see
between "bin/" and "acroread".

This suggests to that the .bashrc file isnt loaded properly. but then if I type echo $LD_PRELOAD in a terminal I get the path to the acroread_exec .so file so .bashrc file must be loaded.

So why wont it work properly if I open firefox from the launcher?

The .bashrc gets executed from bash, the command-line shell, when it is
used in interactive mode. Please, try running the command line below
-----------
firefox
-----------
from a terminal window (I assume thaht [1] the terminal is using bash as a
shell, [2] firefox isn't already running and [3] .bashrc contains correct
'export' lines).
It shoud run the browser and you should be able to verify that the
workaround works; if not so, something bad happened.

So, what can be done? Well, you simply have to customize your graphics
evnironment by putting the export lines in some startup file. Since I don't
personally use that workaround, I don't remember where I put it on the
target machine: let me know wether you've been able to solve and, if not
so, I'll get back to the target machine (next week) and tell you more.

I hope my english is understandable :-)

I can confirm that the LD_PRELOAD method does not work in a x86_64 environment (with 64-bit firefox). The acroread_exec_monitor.so does not preload even if compiled with the -fPIC option. I did not really try to understand why.

However, as suggested by swt-techie, one can compile acroread_interceptor with -m32 and use it to replace acroread on-disk as described in the source code header.

Steps to follow if you are on a x86_64 system:

* change the following line in build_interceptor.sh
    - gcc -Wno-format-security -ggdb -o acroread_interceptor acroread_interceptor.c
    + gcc -m32 -Wno-format-security -ggdb -o acroread_interceptor acroread_interceptor.c
* run build_interceptor.sh
* in /opt/Adobe/Reader9/Reader/intellinux/bin, rename "acroread" to "acroread.original"
* copy the compiled "acroread_interceptor" to /opt/Adobe/Reader9/Reader/intellinux/bin and rename it to "acroread"
* make sure the new "acroread" is executable for all users

This got me rid of this Adobe bug on Oneriric x86_64. Many thanks to Massimiliano for sharing his code.

We are using Firefox 10 ESR on 32Bit Linux and have the same problem. Unfortunaly we have an old kernel 2.6.23 without "SOCK_NONBLOCK"-feature, so I comment the if-clause in the function "accept_connection". Then the acroread_interceptor.c could be compiled - with the "#define WRAPPER_INCARNATION"-Option.

I used the method be renaming the acroread-executable. If I want to look at a PDF in the browser two processes are startet:

/opt/browser/Adobe/Reader9/Reader/intellinux/bin/acroread --display :0.0 -progressPipe 3 -exitPipe 4
/opt/browser/Adobe/Reader9/Reader/intellinux/bin/acroread.original --display :0.0 -progressPipe 7 -exitPipe 9

But I didn't see anything in the Browser.

Can anybody help? Is it okay to comment the if-clause for the old kernel? Do I have to change something else?

Hi all!

I was bitten by this bug too, In our case in a Maverick derived distribution one and using Firefox 4.0.1. It's a kiosk distribution too without a desktop environment (just a Firefox with a custom extension) and this was a critical bug since the kiosk is used for consulting pdfs (among other things). We needed to deploy this patch quickly into the distribution, so I did a (sorry for the dirty 20 minutes) debian package for it. I've just uploaded the source package (lp:~javiube/+junk/acroread-workaround), so you can easily make your own required changes and build it for your distribution. Required lines for .bashrc are not included in the package since we included that into another distribution's package.

Hey Christian, I'm not sure about the change you did, but I guees that commenting the if-clause is a bad idea and you'll need either to define SOCK_NONBLOCK by your own (see http://www.kernel.org/doc/man-pages/online/pages/man2/socket.2.html) or to provide an alternative way for doing this check.

Hope this helps!

Cheers!

Hi, a new acroread release (0.9.4) is available for update, could you give it a try and tell us if the problem persists?
If you still have this bug please set back the status to "new"
thanks

I'm still affected by this. My test case is Ubuntu 12.04.2, 32-bit, fully up to date as of this morning. As I write this my version of firefox is 22.0+build2-0ubuntu.12.04.1 and my version of acroread is 9.5.5-1precise1.

When I start Firefox and open a PDF in a tab, Firefox spawns a plugin-container for nppdf.so, and that in turn spawns an acroread. If I close the PDF tab and wait a few seconds, acroread exits but is not immediately reaped, so a defunct (zombie) acroread remains.

If I try to open another PDF in a tab while the zombie is present, all I get is a black screen.

After a longer time the plugin-container exits, taking the acroread zombie with it. After that, I can open a PDF normally again, since a new plugin-container and acroread are created.

Disabling the out-of-process plugins feature in Firefox globally (dom.ipc.plugins.enabled=false) seems to function as a workaround, but blacklisting only the nppdf plugin (dom.ipc.plugins.enabled.nppdf.so=false) still sometimes gives me a black screen, even though a plugin-container isn't created.

Hello, I'm using Ubuntu 13.04 and I can confirm this problem. I have to kill the npviewer.bin process so I can reload the page and the pdf can be seen again. There's no way to kill the acroread process, nothing will kill it.
