Bug Description

Binary package hint: ubuntuone-client

It seems that Ubuntu One fails to share directories with non-ASCII Unicode chars, in my case accentuated French chars ('é'). Choosing "Synchronize with Ubuntu One" from Nautilus doesn't work, while it's fine if I rename the folder to remove the accent.

This may be related to bug 515920, which is about u1sync failing with non-ASCII chars.

The log from ~/.cache/ubuntuone/log/syncdaemon.log doesn't show any activity, even though the directory to sync seems to be acknowledged:

To test from the terminal, run:

u1sdtool -c
mkdir ~/ÚDF\ Tëst\ éôñßÿç
touch $HOME/ÚDF\ Tëst\ éôñßÿç/test
u1sdtool --create-folder=$HOME/ÚDF\ Tëst\ éôñßÿç

From the GUI:

1. Open Places->Home Folder
2. Click File->Create Folder
3. Name folder: ÚDF Tëst éôñßÿç
4. Double-click on ÚDF Tëst éôñßÿç
5. Right-click and select Create Document->Empty File
6. Name the file "test"
7. Right click on "ÚDF Tëst éôñßÿç" folder and select "Synchronize on Ubuntu One"

Result: https://one.ubuntu.files should show the ÚDF Tëst éôñßÿç folder

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 368626, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

The issue was non UTF-8 compliant filenames in one or more of the files/folders in your ubuntuone folder. This is a known issue. The workaround is to keep the file names & folder names UTF-8 compliant until this issue is resolved.

You can find invalid filenames using the following script:

Sorry, but this is not a duplicate. As I explained in the description, renaming the top directory is enough to fix the problem, and it's in valid UTF-8. I've been using UTF-8 for ages, and all the files in this folder are correctly named:
$ python
You don't have any filenames with broken names

So this bug is really more of a problem, because it means all non-English scripts fail to synchronize. Sounds strange to me that I'm the only one seeing this.

Though, it's true that something is going wrong with encoding here:

But why is ~/.ubuntuone/Purchased from Ubuntu One the problem here, I can't tell.

Chinese and Japanese characters works fine. This must be a subset of valid UTF-8 characters causing the issue.

First item to fix is the udf name decoding in AQ:

# XXX Unicode boundary? = name.decode('utf8')

However after this is applied the UDF is created on the server properly but notification about new UDF fails with:

Like Milan I get

But waiting-metadata gives:

And this seems to block synchronization - the offending file, whatever that may be, is not simply ignored

Not only accents, but other characters provoke the same fault. I have removed accents from filenames, using pyrenamer, and then met "can't encode character u'\xe6'" (which appears to be the Danish character æ) - altered the filenames, and then met "can't encode character u'\xf8' (the character ø) - I have altered filenames and expect to meet "can't encode character u'\xc5'" (the Danish character å) next.
Will follow up on this

I have added the test case but nothing new happens.
Due to the directories that I try to synchronize the error shows up and blocks sync'ing.
When I get the exception - now: UnicodeEncodeError: 'ascii' codec can't encode character u'\xe6' in position 11: ordinal not in range(128) sync'ing runs to a halt.
I have tried to stop sync'ing of the offending directories by right clicking and chosing stop sync - this text is then greyed out, and apparently nothing else happens.
syncdaemon-exceptions log says
2010-05-20 00:03:47,051 - ubuntuone.SyncDaemon.DBus - ERROR - Unable to handle VM_VOLUME_DELETE_ERROR for volume_id=dbus.String(u'pending')
Since my last post I have been almost continually connected, but nothing happens - u1sdtool --status reports 'processing queues' ad infinutum.

The strange thing is, that æ.ø and å don't seem to have any influence in some instances. In my Documents directory directories with these characters do show up, and in some of them also files whose names contain these characters, but at some point, seemingly in directories within directories the problem arises.

As of now I am only able to proceed with sync'ing after starting anew: unsubscribing and removing folders and sudo rm -rf ~/.local/share/ubuntuone && rm -rf ~/.cache/ubuntuone which is rather tedious

Today the ascii error does not show up in waiting-metadate. Instead there is a list of Dirs followed by seemingly unending Queries:

Since it was fixed in trunk a while ago, I assume that maverick's current version (1.3.2) has the fix as well. Closing all the maverick tasks.
