WebDAV lock management

Testing are welcome.
You can set lockemulation to True in http://hg.tryton.org/hgwebdir.cgi/trytond/file/48206780871e/trytond/protocols/webdav.py#l59

I have tested it. with little success:

I have set lockemulation = True

as you suggested. The result is, that Mac OS Finder mounts the share as read/write. So far so good.
BUT: when one tries to write to one of the directories it fails. there is two cases I have tried:
-Opening an existing text file, edit it and write the file back.
-Copying a new file to one folder.
both things fail. In the latter case, the thread doing this file operation locks up. I.e. the trytond is still responding (also to webdav requests) but it has to be killed with SIGKILL if you want to stop it. On the client side (Finder) the copy operation never finishes until the server is killed.

Rewriting a file fails with the following output:

An (essentially) complete log is attached.

Hi again,
another thing (probably unrelated) I noticed when using webdav with ssl was the following:
----------------------------------------
Exception happened during processing of request from ('::ffff:10.0.2.2', 62479, 0, 0)
Traceback (most recent call last):
File "/usr/lib/python2.6/SocketServer.py", line 558, in process_request_thread
self.finish_request(request, client_address)
File "/usr/lib/python2.6/SocketServer.py", line 320, in finish_request
self.RequestHandlerClass(request, client_address, self)
File "/usr/lib/python2.6/SocketServer.py", line 615, in __init__
self.handle()
File "/usr/lib/pymodules/python2.6/DAV/AuthServer.py", line 215, in handle
AuthRequestHandler.handle(self)
File "/usr/lib/pymodules/python2.6/DAV/AuthServer.py", line 80, in handle
self.raw_requestline = self.rfile.readline()
File "/usr/lib/python2.6/socket.py", line 406, in readline
data = self._sock.recv(self._rbufsize)
Error: [('SSL routines', 'SSL23_READ', 'ssl handshake failure')]
----------------------------------------

it appears in quite frequently (on the console, not in the log file). When switching off SSL it is gone. The other errors described before remain.

Just to let you know.
Greetings

And again...,

I found that I was a little bit too impatient with the lockup during copy. After some minutes without killing the server, the copy is aborted and I get the following on the console:

Have a nice weekend,
Christoph

Here is some remarks about the log file:

- it seems that the client try to make ssl connection. Did you activate it?
- you try to fetch pdf report but Ooo failed to start (it is required to convert odt into pdf)
- the client try to write to the root "/" but it is readonly in Tryton. Did you try to mount the database name repository instead of "/"?

Dear Cédric,

Yes it is activated. I also tried without. No change.
> - you try to fetch pdf report but Ooo failed to start (it is
> required to convert odt into pdf)
This is a problem that occurs, when I start trytond on the console to
get a detailed log. Not sure why. But it is not a related problem. The
behaviour remains the same when started using an init script, where Oo
works.
> - the client try to write to the root "/" but it is readonly in
> Tryton. Did you try to mount the database name repository instead of
> "/"?
I also tried mounting the database name. No change.

Greetings,
Christoph.

I'm closing this as webdav is no longer supported.
