WindowsError due to Unicode path issue

[Brian Curtin]

Reported by a user on another bug:

This bug has to be re-opened. I have just installed the latest Ubuntu One Windows Client version 4.0, and the bug is there.

@Beowulf - can you please provide your entire log file?

[Loïc Minier (lool)]

Here's a log that I get; I too have a non-ascii username (Loïc) and U1 is unable to register, to start, and then keeps creating processes unless I kill everything an relaunch it as admin.

The problem is that it tries creating C:\Users\Loïc\AppData\Local\xdg\ubuntuone\syncdaemon\tritcask instead of C:\Loïc\...

[Loïc Minier (lool)]

Oddly, I end up with just tritcask data in C:\Users\Loïc; other U1 files are properly under C:\Users\Loïc. I thought tritcask was just the first os.makedirs().

[Loïc Minier (lool)]

Ah there's an os.makedirs() in tritcask.py at odds with the other ubuntuone.platform.make_dir() calls.

Is there an easy way for me to update tritcask.py on my local install?

[Loïc Minier (lool)]

After patching tritcask.py to use the ubuntuone platform API in r1386 of lp:~lool/ubuntuone-client/tritcask-use-platform-api I get a little further:

[Loïc Minier (lool)]

Ah! The SetFileSecurity error is because I ran Ubuntu One as admin once and hadn't removed C:\Users\Loïc\Ubuntu One between tests (I had only removed the AppData\Local\xdg and \ubuntuone dirs).

Now that I've cleared all files and put back the original windows.py in place, everything works as expected: U1 starts and syncs files just fine, without being launched as admin.

[Loïc Minier (lool)]

So I was over enthuastic with the first path as Ubuntu One only appeared to work properly on the first run; there were probably errors that I hadn't noticed in the large log from the initial sync. Subsequent runs wouldn't work at all anyway.

I've pushed a bunch of other revs to deal with other os.* calls in tritcask.py, and now U1 works for me, I can quit and start again.

[stimanov (stimanov)]

Looks like this my bug report - https://bugs.launchpad.net/ubuntuone-client/+bug/1121255 - of the same nature.

I'm just curious why sync folder in Windows is always located in the user profile folder and can not be placed in some other place.

[stimanov (stimanov)]

I was wrong. Published bugfix didn't solve my problem (post #10).

[Loïc Minier (lool)]

Did you try starting U1 with admin privileges, and now you're trying to start without these? I had similar symptis at some point, and that requires fixing the permissions of various folders, or removing them.

[stimanov (stimanov)]

No. My account which consists of unicode characters is not admin one. At the same time U1 works well on the same computer with another non-admin account which consists of English characters only.

[Beowulf (s-highlander)]

 tpThis bug emerged after upgrading U1 Windows Client from 2.0.0 to 4.0.0. So I don't think this is relates to permissions, because the previous version worked fine with the same permissions.

[Loïc Minier (lool)]

stimanov, did you actually deploy the latest changes manually? I've tried updating to the latest published version, and it doesn't seem to include a fix for this bug yet (I'm getting the bug with when I wasn't with the fixes applied locally).

[dobey (dobey)]

This bug is not fixed in the latest release of Ubuntu One for Windows. It is only fixed in our trunk source repository at the moment.

[stimanov (stimanov)]

Ok. Now it's clear.

[stimanov (stimanov)]

Just one question (sorry, i'm newbie on this forum) - how can i get the info that mentioned bug is resolved in the latest release?
