Description Joost Kraaijeveld CLA 2007-06-26 01:28:29 EDT 
1. Install eclipse with the plugins as in the attachment
2. Start working 
3. After a while the exceptions below come one by one and they make it quit impossible to keep working with Eclipse.

I noticed in the .mylin directory "0" (NULL) sized zip files (see also the last remark after the "ls"):

Comment 1 Joost Kraaijeveld CLA 2007-06-26 01:30:39 EDT 
Created attachment 72446 [details]
Eclipse configuration
Comment 2 Mik Kersten CLA 2007-06-26 10:17:55 EDT 
Is there any reason why Mylyn is not able to write into that directory?  E.g. the files got created by a different user or with different permissions?

Rob: in the least we need better error handling of the case where the the files cannot be written.

We probably should add test if folder if writable and warn the user about that.
Comment 4 Joost Kraaijeveld CLA 2007-06-26 10:56:57 EDT 
The directory itself is writable by the user and Eclipse is started by the same user: see also the output of ls -al * in my bug report.
Comment 5 Robert Elves CLA 2007-06-26 11:40:15 EDT 
Joost, is there anything special/custom about the linux distro you are using? Are you missing some gzip libraries perhaps? I'm not certain but java likely uses them for zipping on the linux platform.

We can open a dialog reporting the failure to write.  We could also revert to not zipping. Of course we'd have to check for these on reading as well so will take some time.

Unlikely, because same library is used to read jar archives.

BTW, it isn't gcj by any chance?
Comment 7 Joost Kraaijeveld CLA 2007-06-26 12:30:03 EDT 
My distribution is Debian and my JDK is Sun's 1.5-11 for AMD64.

I am not missing gzip libraries. As you can see there from the "ls" output and my remark in the initial bug report there are actually zip files created.

I do have some light in my tunnel: after filing my bug report I decided to close down Eclipse, remove the complete .mylyn directory from the .metadata directory and restart Eclipse. I have not has the errors since.

Okay great, please keep us posted.
Comment 9 Robert Elves CLA 2008-04-05 19:49:09 EDT 
All externalization will be improved for 3.0. Tracking on bug#183683
