Summary0000453: Cannot create tar.bz2 archive
DescriptionWhen trying to create a tar.bz2 archive, tar is created but bzip2 aborts, leaving the tar and a bz2 of size 0.

A popup panel tells that
Error:
Access violation

Please report this error to the bug tracker with a description of what you were doing and the following file:
/home/peter/.config/doublecmd/doublecmd.err

Press Ignore to continue or Abort to abort the program.

tar.gz works fine, zip as well
when tar.bz2 is created in a terminal by ``$ tar -cjvf c2.tar.bz2 c2'', DC is unable to open the archive and reports Access violation
Steps To ReproduceSelect a dirtectory in the left panel,
Click on Pack files...,
Select Packer bz2
Click OK

In the error notification window, Ignore terminates the operation and DC works on, but Abort hangs and DC has to be killed.

Debug info seems wrong. Can you also try this using this version of DC with the plugin above:

The bad news is that I seem to be unable to make work it again: yesterday I figured out that I had to change the user in the selinux context of the debugger wcx file.

Today DC won't load the debugger wcx file even if all unix and selinux permissions are set correctly. It keeps saying that "Cannot load ...." and the funny thing is that it says the same when I remove the wcx file from the zip directory.

The original wcx still loads but fails to work as described.

Do you have any clue?

If you run DC from console does it print out anything when you try to open archive, like "cannot open shared object file"? The plugin also needs to load libbz2 at start and when it can't you get the same message "Cannot load...". Also, confirm that the path to the plugin is set correctly in Options. To check, when you select the plugin in Options, press Configure and it should show the configuration window.

Configure does not work, says:

If the plugin is loaded it should output on console:
Zip plugin is loaded

Some reasons it is not loaded might be:
1) Path to the plugin is wrong (file not exists)
2) File is invalid, for you
   $ file /usr/lib64/doublecmd/plugins/wcx/zip/zip.wcx
   should show something like:
   ELF 64-bit LSB shared object, x86-64
   I have checked myself that I uploaded 64-bit version of the plugin.
3) It cannot load libbz2 (file not exists or is not 64-bit)

Can you check with:
$ ldd zip.wcx
if correct library is found.

I have added showing error message from the dynamic lib loader in this build:
http://ifile.it/j2tb93h

If you don't figure it out, try running it and it should show on the console the error message why the plugin is not loaded.

Thank you for the help!

Now we've got the debug info on the bzip2 failure:

I had to create a new symlink /lib64/libbz2.so.1.0 because of this:

If you look back, my bzip2 looks for libbz2.so.1, which has always existed in /lib64. Actaually I have this:

Yes, I remember that Fedora doesn't have this symlink libbz2.so.1.0, although for example Ubuntu and Debian do. On Debian, where I built the plugin, libbz2.so points to libbz2.so.1.0 so maybe that's why it needs this symlink.

The debug info still seems wrong or at least missing something in between. FPC has some bugs regarding giving debug info.

Can you try using the build I posted before:
http://ifile.it/xyhfpbl

Or if you have GDB installed then:
$ gdb -ex run -ex "set logging file /tmp/dc.log" -ex "set pagination off" -ex "set logging on" -ex "bt full" /usr/lib64/doublecmd/doublecmd
After it crashes it should dump the log to /tmp/dc.log.

I used the one you had posted earlier (Revision: Unknown). Nevertheless, I downloaded it again from the link and copied it to DC install dir. Maybe that's why the line number in heap.inc differs from the previous result.
 
The gdb log:
#0 SYSFREEMEM (P=0xd9d8) at ../inc/heap.inc:1186
        result = 30
        SYSFREEMEM = 30
        RESULT = 30
        PMC = 0xd9d0
        LOC_FREELISTS = 0x7fffefbaa368

#2 0x0000000000000000 in ?? ()
No symbol table info available.
Missing separate debuginfos, use: debuginfo-install doublecmd-gtk-0.5.4-2.1.x86_
A debugging session is active.

        Inferior 1 [process 2411] will be killed.

Quit anyway? (y or n)


This time DC didn't arrive to the Ignore/Abort dialog, but otherwise the effect was the same: a normal tar file, and a bz2 file of 0 length.


debuginfo-install said:
Could not find debuginfo for main pkg: doublecmd-gtk-0.5.4-2.1.x86_64,
it found a half a dozen others,but I refrained from downloading them.

OK, thanks.
I think maybe memory overwriting happens because we cannot get proper debug info on this. I can't find the error this way and I can't reproduce on my machine, so I'll have to leave it unresolved for now.

 Now bz2 creation and open ***works***, all other archivers work as well except rar: doubleclicking on a rar file does not open it, instead I get a "Cannot open existing file" error message. (But rar has not been working for quite a long time.)

You need to install libunrar package (see my repo https://build.opensuse.org/package/show/home:Alexx2000/libunrar) for .rar support.

I did not know that, but in the meantime I found an other solution:
- got and installed rar from here: http://www.rarlab.com/download.htm
- reconfigured DC like this:
-- DC/Configuration/Options/Plugins: disable unrar
-- DC/Configuration/Options/Archivers/RAR/Adding: changed
     %P a -y {-p%W} {-v%V} {%S} %AQA @%LQ
      to
     rar a {-p%W} {-v%V} {%S} %AQA @%LQ

(The last step was because in the original config %P must have stood for unrar, then rar wouldn't take -y)
