[Zope-CMF] Davfs and Webdav in CMF-Portal's skins -- problems, how to debug

[Heimo Laukkanen]

Hi all,

I've mounted zope 2.6 through davfs to a directory on my Linux Redhat 
8.0 box - and noticed now some problems with changes that I try to make 
in CMF Portal's page templates in skins-tool. These problem *are not* 
happening *outside* of the portals_skins tool!

I can start to edit a pagetemplate in custom folder and save it. However 
there are times when the saving takes many seconds - even ten seconds - 
and changes are not saved into ZODB, even though the program thinks it 
just saved the file. And this does not happen with all the files.

So far I have seen the following.

  1) I can create new files through webdav and edit them from webdav and 
ZMI, no problem. Some delays can be seen from time to time, meaning that 
after I samed trhough webdav and did refresh, changes were not visible 
in first refresh.

  2) Sometimes via webdav I have saved a file, edited in pico. When I 
tried to see it via webdav with less - then changes were not visible, 
but became visible after I opened the file in editor again.

  3) There are files like index_html and similar that came with this 
imported CMF Portal to my box. These files seem to un editable trough 
the webdav and create these problems that the editor thinks it has saved 
the file, however changes are not made to the ZODB.

And as a reminder - these problems happen only inside the portal_skins-tool!

Has anyone else seen similar behaviour, is there something tobe done, 
how could I do more thorough debugging so that I could provide 
sufficient information for programers to fix this issue.

Thanks.
