[Spice-devel] Webdav on Windows XP

[Koopa Koopa]

Hi all,

I'm trying to setup a Windows XP SP3 virtual machine with SPICE folder
sharing. The latest version, v2.4, fails to install, as the
spice-webdavd service fails to start. Running spice-webdavd.exe
manually yields the error message "The procedure entry point
AcquireSRWLockExclusive could not be located in the dynamic link
library KERNEL32.dll", which seems to be a deficiency in using XP [1].
After some digging, I've determined that the cause of this is that,
when starting the service, spice-webdavd calls g_mutex_lock from Glib
[2], which had XP support removed a couple of years ago [3].

Version v2.2, which comes from before the Glib change was made,
successfully installs and runs. I have been able to map and somewhat
use a network drive mapped to the share, but it has broken and I can't
seem to get it working again; Windows just says that "The network path
http://localhost:9843 could not be found." Strangely enough, when
going to that address in Mypal, the share directory is displayed
without any issues, and I can browse it.

If this configuration is not supported, I totally understand. Part of
why I want to point this out is so that, at the very least, this
incompatibility could be added to the Spice User Manual [4]. Thanks!
