Attachments:	Ark window is empty opening this 7Z file.

Description Parameshwara Bhat 2011-02-10 10:18:27 UTC

Version:           2.14 (using KDE 4.4.4) 
OS:                Linux

Ark cannot handle 7z and *.rpm archives whereas file-roller has no problem with them.
When I tried to open a 7z archive, Ark did not open it and did not even produce any error message about unsupported type etc.,

Reproducible: Always

Steps to Reproduce:
Just open a file with .7z and .rpm extension



OS: Linux (i686) release 2.6.34.7-0.7-default
Compiler: gcc

Comment 1 Raphael Kubo da Costa 2011-02-10 15:03:42 UTC

Ark has supported 7z files for quite some time, and rpm support has been implemented in the upcoming 4.7.0 release.

What error message do you get when you try to open a 7z archive? You only need to have p7zip installed.

Comment 2 Parameshwara Bhat 2011-02-10 15:27:09 UTC

Look at the output below.

           pbhat@linux-9x1k:~> rpm -qa|grep p7zip
           p7zip-9.13-1.pm.7.1.i586
           pbhat@linux-9x1k:~> cd Temp
           pbhat@linux-9x1k:~/Temp> ark ToDoList.7z 
I see no error message in the GUI or when called from the console as above. File-roller which may also depend upon p7zip works fine.

Thanks.

Comment 3 Raphael Kubo da Costa 2011-02-10 16:35:43 UTC

Does '7z l -slt ToDoList.7z' work as expected?

Comment 4 Parameshwara Bhat 2011-02-11 07:14:40 UTC

Yes. Please look at the output below.

pbhat@linux-9x1k:~> cd Temp/
pbhat@linux-9x1k:~/Temp> ls -l ToDoList.7z 
-rw-r--r-- 1 pbhat users 290055 2011-02-10 19:45 ToDoList.7z

Comment 5 Raphael Kubo da Costa 2011-02-11 17:12:03 UTC

Does it happen to any 7z file? Can you attach one sample file that causes the problem?

Furthermore, can you try using a newer KDE SC version? 4.4.4 is a bit old, and the problem can have already been solved in a newer release.

Comment 6 Parameshwara Bhat 2011-02-20 12:32:43 UTC

Created attachment 57391 [details]
Ark window is empty opening this 7Z file.

Please see the attachment which is not opened by Ark.

Sorry I cannot upgrade till Opensuse 11.4 is released.That is to ensure my daily work is not affected by the possible bugs.

Comment 7 Raphael Kubo da Costa 2011-02-20 18:30:48 UTC

Hmm, this is actually a zip file with a 7z extension.

I've uncovered some bugs here in Ark, a fix should be out soon. Thanks for the report.

Comment 8 Parameshwara Bhat 2011-02-20 19:07:42 UTC

That should mean file-roller is able to recognise this disguised zip file, but not Ark. Hope Ark will soon have the same dependability as file-roller.

cheers.

Git commit d3d3e5928b56db8446bac42ea334d940a3b7b37b by Ragnar Thomsen.
Committed on 10/09/2015 at 06:39.
Pushed by rthomsen into branch 'Applications/15.08'.

Improve detection of mimetype when opening archive

Previously, the filename extension had higher priority than file content
when determining mimetype. When opening an archive that had a wrong
extension (as in bug 265971), this resulted in Ark failing to open it.
With this commit the mimetype is determined from file content.
Additionally, a warning is shown in console output when mimetype from
extension and content do not match.

For tar.gz, tar.bz2 and tar.xz archives, the mimetype from filename
extension is still used. This is due to these archives being detected as
singlefile gz, bz2 and xz archives when using content, and Ark would
then use the singlefileplugin instead of the libarchive plugin.
