Re: Make test drill, next steps, call for help with Winetest

I have written attached script to facilitate automated winetest runs. It needs a VirtualBox virtual machine with either Windows or a Wine platform configured to run autorun.inf files. The script downloads the latest winetest binary and puts it in an iso image, along with an autorun file to trigger its execution when the image is 'inserted' into the virtual drive. A snapshot is used to revert the vm to its original state, so no need to worry about winetest screwing up your installation. -Hans #!/bin/bash if [ $# -lt 2 ]; then echo "Usage: $0 <vmname> <tag>" echo "" echo "vmname: Virtual machine to use (must be in suspended state). echo "tag: Tag built from [-.0-9a-zA-Z] to identify test report. exit 1 fi TMPDIR=/tmp/winetest$$ LOGFILE=$TMPDIR/log mkdir -p $TMPDIR/master echo "downloading winetest binary" wget -P $TMPDIR http://www.astro.gla.ac.uk/users/paulm/WRT/CrossBuilt/winetest-latest.exe >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi mv $TMPDIR/winetest-latest.exe $TMPDIR/master/winetest.exe echo "creating autorun.inf" cat > $TMPDIR/master/autorun.inf <<_EOF_ [autorun] open=winetest.exe -q -t $2 _EOF_ echo "creating cd image" mkisofs -o $TMPDIR/winetest.iso $TMPDIR/master >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "checking vm $1 state" VBoxManage showvminfo $1 | grep "^State:" | grep "saved" >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "creating snapshot for vm $1" VBoxManage snapshot $1 take before-winetest >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "starting vm $1" VBoxManage startvm $1 >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "waiting until vm $1 is up and running" RUNNING="false" while [ $RUNNING != "true" ] do VBoxManage showvminfo $1 | grep "^State:" | grep "running" >> $LOGFILE 2>&1 if [ $? -eq 0 ]; then RUNNING="true" fi sleep 1 done echo "attaching cd image to vm $1" VBoxManage controlvm $1 dvdattach $TMPDIR/winetest.iso >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "sleeping while vm $1 runs winetest" sleep 1800 # 30 minutes should be enough for winetest to finish echo "suspending vm $1" VBoxManage controlvm $1 savestate >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi echo "waiting until vm $1 is suspended" SAVED="false" while [ $SAVED != "true" ] do VBoxManage showvminfo $1 | grep "^State:" | grep "saved" >> $LOGFILE 2>&1 if [ $? -eq 0 ]; then SAVED="true" fi sleep 1 done echo "reverting vm $1 to previous state" VBoxManage snapshot $1 discardcurrent -all >> $LOGFILE 2>&1 if [ $? -ne 0 ]; then exit 1 fi rm -rf $TMPDIR exit 0

Bug in dlls/oleaut32/tests/vartype.c?
by Gerald Pfeifer 01 Nov '07

01 Nov '07

dlls/oleaut32/tests/vartype.c has the following snippet of code: + f = -1e-400; /* deliberately cause underflow */ + hres = pVarBstrFromR4(f, lcid, 0, &bstr); + ok(hres == S_OK, "got hres 0x%08lx\n", hres); + if (bstr) + { + todo_wine ok(memcmp(bstr, szZero, sizeof(szZero)) == 0, "negative zero (got %s)\n", wtoascii(bstr)); + } which was added in revision 1.27 Alex Villacís Lasso <a_villacis(a)palosanto.com> Test for behavior of negative underflow formatting. This doesn't seem to work as intended, because it is a floating point *constant* which current versions of GCC simply truncate to 0.0.

New DLL, Server and Service Documentation
by Roy Shea 01 Nov '07

01 Nov '07

Howdy All, This autumn I began learning both Wine and COM. A combination of limited documentation and trouble finding the right example code for my task at hand made this a difficult process. In an attempt to help other new Wine and COM developers I wrote a tutorial on COM development the Wine way. This tutorial describes: - A simple DLL providing a in-process COM object - A simple server providing a local COM object - A simple service that publishes a COM object and the corresponding proxy / stub required to use the service with instructions on Wine integration and, for Windows users or testers building for Windows, basic instructions on building and running these same applications in Windows. The tutorial is available at: http://ambleramble.org/wine/ I hope other developers enjoy this documentation. If you see mistakes, either minor typos or conceptual problems, please drop me an email and I'll clean up the docs. Peace, -Roy

Re: wined3d: Enable clip planes with GLSL shader backend
by Ivan Gyurdiev 01 Nov '07

01 Nov '07

> + if (use_vs(stateblock->wineD3DDevice) && stateblock->wineD3DDevice->vs_selected_mode == SHADER_ARB) GLSL specific logic should go in glsl_shader.c. Please try to get away from writing code in terms of flags and if statements - use the OOP model. Backend-specific logic should be removed from pixelshader and vertexshader too...
