Hi experts.
I got encounterd a strange issue using curl.exe on Windows Server 2008.
Next command success to upload files but sometimes no result has returned on
standard output.
$ curl.exe -iT test.doc http://localhost/dav/test.doc
for example, I made next script named 'curlupload.py' by python. This script
can upload a lot of files to WevDav folder http://localhost:60000/dav/.
Please prepare 'files' folder and put 'test-core.doc' file(60KB) into folder before
execute next script.
--
import os, shutil, popen2
dir = 'files/'
for i in range(1000):
file = 'test-%05d.doc' % (i + 1)
if not os.path.exists(dir + file):
shutil.copyfile(dir + 'test-core.doc', dir + file)
cmd = 'curl.exe -iT %s%s http://localhost:60000/dav/%s' % (dir, file, file)
(stdout, stdin, stderr) = popen2.popen3(cmd)
print '*** ' + file
for line in stdout:
print line

I executed like this.
$ python curlupload.py > result.txt
Then we could see some result from server had disappear. The result of test-00686.doc
has gone somewhere like this.

These are all I know so far.
1. This happens 1 or 2 times per 1000 files uploads.
2. This happends only with curl-7.19.5 or higher. curl-7.19.4 works always fine.
3. This happenes only Windows Server 2008. Windows Server 2003 works always fine.
I haven't checked any other environments (Linux, Mac OSX...).
4. This is not the matter of WevDav server. because I tried some kind of servers,
apache and NetApp. The result was always same.
5. I used binary of curl.exe from download site and I build binary from source code.
The result was always same.
I want to use latest version of curl. So please tell me some advice.
Thank you for your kindness in advance.
