Mylyn not able to parse backup files !!! [message #49263]

After updating from m7 to rc2 i got into an incredible mess.
First I ran into one crash(most likely due to Mylyn) after another reading my workspace.
Now it finally works but Mylyn cannot read its own backup data properly.
I guess thats the worst thing a software can do - not be able to read your own backup data.
All categories are empty. Everything is now put into uncategorized. Dozens of tasks.
Some tasks seems to be empty.

Mylyn seems to get more and more buggy. One time - after switching tasks - all editors gone
next time nothing changes at all - the editors stay the same.

And the newest thing: two tasks stay active all the time. I cannot turn the old task off.

Sorry I did not file a bug report. I am pissed and too busy and I lost my account data too.

I need to delete the .mylyn directory of the workspace.
Taskview shows up without errors.
Restore from Backup. Task Data are restored almost right.
One task is empty.

Andreas:

It looks like your Mylyn was partially updated, either due to a network
problem or an install/p2 problem. Could you please file a bug against
Mylyn with this stack trace and let us know how up updated/installed?

In the meantime, if you have any more problems with the 3.0 RCs please
do the following:

1) Uninstall or delete the old plug-ins. Make sure you leave the
<workspace>/.mylyn directory around since it holds the snapshots.

2) Install Mylyn 2.3.x from: http://www.eclipse.org/mylyn/downloads/

3) Restore tasks from a backup if they disappeared, via the Task List's
view menu.

Mik

If you activate a task that has not been activated beforethe open editors
will remain open. Please file a bug if the activated task had been
activated before.

I have filed a new bug and will investigate that:

The account data is stored in the eclipse keystore. The default location
depends on your operating system but you can force it to a particular
location to share it between Eclipse installations, e.g.:

eclipse -keystore ~/.eclipsekeystore

Didn't Eclipse Platform changed implementation and storage of that
data in 3.4? I saw note for CVS plugin that users would have to re-enter
credentials. Though Task Repositories details always been stored outside
of keystore and shouldn't be lost.

Yes, Eclipse 3.4 includes the new Equinox Security framework that is used by
CVS. Mylyn does make not use of the new APIs at this point and is still
using the old keystore.
