X-Git-Tag: 1.0.80~19 X-Git-Url: http://git.annexia.org/?p=libguestfs.git;a=commitdiff_plain;h=4d53df4d7399d35b51bd69d76e00539d1de825e0 daemon/Win32: Add contributed test script to test daemon using Wine. This test script allows you to test limited features of the Windows daemon by running it on a standard Fedora host using Wine.

Read this to understand the +# purpose of QEMU wrappers: +# http://libguestfs.org/guestfs.3.html#qemu_wrappers +# +# With this script, the qemu program is not actually run. Instead we +# pretend to be qemu, parse out the necessary parts of the long +# command line that libguestfs passes to qemu, and run the Windows +# daemon, under Wine, with the right command line. The Windows daemon +# then hopefully connects back to the libguestfs socket, and as far as +# the libguestfs program is concerned, it looks like a full appliance +# is running. +# +# To use this script, you must set the environment variable +# LIBGUESTFS_QEMU=/path/to/contrib/guestfsd-in-wine.sh (ie. the path +# to this script). +# +# You can then run libguestfs test programs, and (hopefully!) they'll +# use the Windows guestfsd.exe, simulating calls using Wine. +# +# For example from the top build directory: +# +# LIBGUESTFS_QEMU=contrib/guestfsd-in-wine.sh fish/guestfish +# +# You might also need to set the environment variable LIBGUESTFS_PATH +# to point to an appliance. The appliance will never be used, but +# libguestfs needs to find one. +# +# Another suggested environment variable is LIBGUESTFS_DEBUG=1 which +# will give you must more detail about what is going on. Also look at +# the contents of the log file 'guestfsd-in-wine.log' after each run. +# +#---------------------------------------------------------------------- + +# Note that stdout & stderr messages will get eaten by libguestfs +# early on in the process.
