|0004340||Slicer4||Core: Base Code||public||2017-02-09 22:49||2017-11-04 15:45|
|Product Version||Slicer 4.8.0|
|Target Version||Slicer 4.9.0||Fixed in Version||Slicer 4.9.0|
|Summary||0004340: Impossible to use Slicer in multi-user setting on Linux|
Slicer temporary directory is owned by the user who started Slicer first and is not writeable. Issue identified by Artem Mamonov.
|Steps To Reproduce|
I was going to suggest the workaround of setting the temp directory but Artem found it before I had a chance.
It does make sense and it does sound like a bug that would be hit on a multi-user linux system.
Artem, since you are the discoverer of the bug would you mind filing a bug report so we can track this?
For reference the default is set here:
Which uses Qt calls as described here:
In the future I think we'll want to migrate to this call once we have Qt5:
We can probably implement a workaround in the mean time that appends the user name to the temp file path, so something like /tmp/Slicer-artem would be used and should work 99% of the time I think.

Thanks for reporting the issue.
Waiting we transition to Qt5, I suggest that function "defaultTemporaryPath" is updated to use something like what is done here: https://github.com/commontk/CTK/blob/cdb75ce742f618112b8a0f299a484d00baa4e8ff/Applications/ctkPluginGenerator/ctkPluginGenerator.cpp#L45-L70
This is not a blocking issue, as a workaround is available:
I think chances are it is definitely blocking for someone who just downloaded Slicer, and has no idea about what the problem or the workarounds are.
This issue is not new, and it has not prevented creating several stable versions. This is just one of many issues that users can solve without any software change, if they ask in the forum. Probably there are only very few Linux users, many of them do not have the issue or figure out the solution, because I don't see people complaining about it (even if only 1 out of 10 people reports the issue, we should see complaints coming in). Anyway, fix is scheduled for 4.8.
Submitted pull request with proposed fix:
Fix integrated into r26549.
On unix-like systems, username is now appended to temporary directory name: (SystemTemporaryDir)/(ApplicationName)-(UserName)
