Hi Ben, thanks for the links. Apparently it is not needed to go to such a deep level :-) I know of Wireshark but haven't heard of Fiddler until now. But it is good to know that there are different tools available.

Hello Sven, I had some time to look further into this issue.

I took the query from the http client request which I inspected in the debugger. When the 'queryAt:...' line is commented out the contents of the repository is shown when I choose 'Open' on the specific repository in MonticelloBrowser. Maybe this is an issue with the WebDAV implementation of OwnCloud (version 5.0.10 in this case). The next strange thing here is that all entries in the opened browser are prefixed with 'remote.php/webdav/monticello<https://owncloud.server.de/remote.php/webdav/monticello> /'. And they are all marked in a bold font which means completely new to the system if I remember correctly. Then I checked the MD5 sums of the .mcz files and the ones from the package cache have a different checksum than the one on the webdav share. Although I used the MonticelloBrowser 'Copy' action.

Two progress bars for each progress in #20623?

by MartinW

Recently (for example in #20623) i see two progress bars for each progress. Is this only an optical glitch - or is it something to worry about?

Hi all, I wonder is there any effort in the Smalltalk world towards having interactive parallel Smalltalk like IPython parallel framework? http://ipython.org/ipython-doc/dev/parallel/index.html Cheers, HernÃ¡n
