net_dav can put textfile only?

[sanemat]

I want to put imagefile.
But I see raised error
ArgumentError: Content-Length not given and Transfer-Encoding is not `chunked'

[devrandom]

Do you have any sample code that replicates the issue?

[sanemat]

My code is below.
Is this wrong style of writing?

dav = Net::DAV.new('https://example.com/webdav/')
file = '1px.gif'
File.open(file, "rb") {|stream|
    dav.put(file, stream, File.size(file))
}

[devrandom]

It works fine when I try it. Can you make sure that File.size(file) returns a number greater than zero?

[sanemat]

Yes, File.size(file) returns 6.

[devrandom]

Hm... puzzling. What version of ruby and what OS are you on? Do you have the curb gem installed?

[sanemat]

my version
OS : Fedora12(i686)
Ruby : 1.8.7-p299, 1.9.2-rc1, REE1.8.6 (used rvm)
net_dav: 0.5.0
curb : 0.7.7.1
curl : 7.19.7

That's pretty recent, so probably not a ruby version problem.

We set the content_length in request_sending_stream(verb, path, stream, length, headers), so I don't see how this can happen.

I'll try to create a VM with fedora12, but it may take awhile. You might want to try using rdebug to step through the code and see if you can identify the issue.

[devrandom]

I believe I identified the issue. A new commit has been applied - 2728a01 . Please try it and let me know.

[antz29]

bump! :) we are getting the same error on ruby 1.9.2 we are sending a text file using the same code as above.

[devrandom]

I can't replicate this, and content_length seems to be carried along. Could you add some print statements to see if req.content_length is blank in the web_dav gem?

[mconigliaro]

Same problem here.

For what it's worth, I believe the error message from Net::HTTP is erroneous. Using netcat (nc -l 30080), I can see that the Content-Length header is in fact being sent with the request:

PUT /cargohold/testing.txt HTTP/1.1
Accept: */*
User-Agent: Ruby
Content-Length: 100
Content-Type: text/xml; charset="utf-8"
Connection: close
Host: localhost:30080

OK guys, this definitely has something to do with authentication. Notice that in my last comment, no Authorization header gets sent with the request. I also get 401 (Unauthorized) errors in the logs when I run my test script against a real server. Disabling authentication on the server allows the script to work again.

[devrandom]

Are you able to post headers of the failure? There should be two requests, one without auto, and one with. There should be two requests, one without credentials which gets a 401. The second should be with credentials. Perhaps the second is not sending content-length.

[devrandom]

I just tried it locally with ruby 1.8 and 1.9, and it works as expected. The authentication is sent on the second requests, and the content-length header is present in both requests.
