Here are the logs from wireshark when I drag 'n drop a file in a webdav folder.

First in Windows XP (works):
4    0.000488000    10.0.2.15    192.168.2.60    HTTP    449    HEAD /gpig/Fichiers/P1/P2/blabla.txt HTTP/1.1
6    0.961614000    192.168.2.60    10.0.2.15    HTTP    452    HTTP/1.1 404 Not Found
8    0.978979000    10.0.2.15    192.168.2.60    HTTP    579    PUT /gpig/Fichiers/P1/P2/blabla.txt HTTP/1.1
                                                                (Content-Length: 525)

Then in Windows 7 (does not work):
76    13.341865000    10.0.2.15    192.168.2.60    HTTP    428    PROPFIND /gpig/Fichiers/P1/P6/Tracker_Import_FieldNotEmpty.xml HTTP/1.1

                                                                  (Content-Length: 0)

87    13.615585000    10.0.2.15    192.168.2.60    HTTP/XML    252    LOCK /gpig/Fichiers/P1/P6/Tracker_Import_FieldNotEmpty.xml HTTP/1.1

93    13.849843000    192.168.2.60    10.0.2.15    HTTP    439    HTTP/1.1 200 OK
105    13.857509000    10.0.2.15    192.168.2.60    HTTP    56    PUT /gpig/Fichiers/P1/P6/Tracker_Import_FieldNotEmpty.xml HTTP/1.1
                                                                  (Content-Length: 12290)
107    13.943367000    192.168.2.60    10.0.2.15    HTTP/XML    746    HTTP/1.1 403 Forbidden 

We can see that with Windows 7, two requests are done to create a file. One PUT to create an empty file (#81: Content-Length: 0) and another one to PUT the content (#105: Content-Length: 12290).

The Windows 7 workflow is not compatible with the current implementation.

1. File release system does not allow to create empty files via webdav (bug due to a bad check on file creation WebDAVFRSRelease L.530, hacked to be able to run the experimentation)
2. File release system does not allow to modify a file via webdav (thus the 403 Forbidden after the secound PUT)

Dear personal diary,

I'm desperate. For the fun I tried to upload a file to docman via webdav, using the built-in client in Windows 7. It works.

Therefore my previous assumption about incompatibilities between built-in client and sabredav seems to be wrong.

It works with Windows XP but not with Windows 7.

I think that the issue comes from the incompatibilities between webdav in Tuleap and the built-in client in Windows 7. Maybe SabreDav should be upgraded? Our version is 1.4 (end of support in Nov 2012): http://sabre.io/dav/install/ It seems that some compatibility issues have been fixed in subsequent versions of the lib (see changelog https://github.com/fruux/sabre-dav/releases).

> I suspect that this comes from the fact that fileforge (updated in this commit) has not been redeployed on my dev environment.

Confirmed. After redeployment of fileforge.pl it works locally.

git bisect reveals that the issue have been introduced at commit #e1c8c096851358caa54993e7785d4cfbc587b581

I suspect that this comes from the fact that fileforge (updated in this commit) has not been redeployed on my dev environment.

Continuing investigations…
