OLEAUT32: bug 4502 - request for comment before trying to fix
by Alex Villacís Lasso 15 Mar '06

15 Mar '06

I would like to draw attention to bug 4502. This bug can cause any VB application to crash when the DatePicker control is used, and an attempt is made to assign a date value in VB code. Even though I found this bug while testing an application I wrote, this might not be specific to this application. It is only recently that I have some time to dedicate to this bug, but I would like somebody to comment on this. When the sample application is run with WINEDEBUG=ole,variant, the failing invocation looks like this: trace:ole:ITypeInfo_fnInvoke (0x7fdd5440)(0x7fd9f61c,id=20,flags=0x00000004,0x7fa3ee8c,(nil),0x7fa3ee6c,0x7fa3ee9c) trace:ole:dump_DispParms args=1 named args=1 trace:ole:dump_Variant 0x7fa3eef4->{VT_DATE(38788,0x7fa3ec7c) trace:variant:VarUdateFromDate (38788,0x00000000,0x7fa3ec36) trace:ole:dump_Variant ,2006/03/12 00:00:00} trace:ole:ITypeInfo_fnInvoke invoking: L"Value"(1) parm0: L"Value" memid is 00000014 Param 0: tdesc.vartype 12 (VT_VARIANT) u.paramdesc.wParamFlags PARAMFLAG_FIN u.paramdesc.lpex (nil) funckind: 1 (pure virtual) invkind: 4 (property put) callconv: 4 (stdcall) oVft: 224 cParamsOpt: 0 wFlags: 3c elemdescFunc (return value type): tdesc.vartype 25 (VT_HRESULT) u.paramdesc.wParamFlags PARAMFLAGS_NONE u.paramdesc.lpex (nil) helpstring: L"Returns/sets the current date." entry: (null) trace:ole:ITypeInfo_fnInvoke changing args trace:ole:dump_Variant 0x7fa3eef4->{VT_DATE(38788,0x7fa3ec7c) trace:variant:VarUdateFromDate (38788,0x00000000,0x7fa3ec36) trace:ole:dump_Variant ,2006/03/12 00:00:00} trace:variant:VariantChangeTypeEx (0x7fdd5520->(VT_DATE),0x7fa3eef4->(VT_DATE),0x00000400,0x0000,VT_VARIANT) trace:variant:VariantClear (0x7fa3ec40->(VT_EMPTY)) trace:variant:VariantClear (0x7fa3ec30->(VT_EMPTY)) trace:variant:VariantCopyInd (0x7fa3ec30->(VT_EMPTY),0x7fa3eef4->(VT_DATE)) trace:variant:VariantCopy (0x7fa3ec30->(VT_EMPTY),0x7fa3eef4->(VT_DATE)) trace:variant:VariantClear (0x7fa3ec30->(VT_EMPTY)) trace:variant:VARIANT_Coerce (0x7fa3ec40->(VT_EMPTY),0x00000400,0x0000,0x7fa3ec30->(VT_DATE),VT_VARIANT) trace:variant:VariantClear (0x7fa3ec40->(VT_EMPTY)) trace:variant:VariantClear (0x7fa3ec30->(VT_DATE)) trace:variant:VariantChangeTypeEx returning 0x80020005, 0x7fdd5520->(VT_DATE) err:ole:ITypeInfo_fnInvoke failed to convert param 0 to VT_VARIANT from VT_DATE trace:ole:ITypeInfo_fnInvoke -- 0x80020005 The Property Put seems to be declared as taking one VT_VARIANT parameter, and the VB code supplies a VT_DATE value. Therefore, an attempt is made to coerce VT_DATE --> VT_VARIANT. However, VariantChangeTypeEx() does not support conversion of *any* kind of variant into VT_VARIANT, so the call fails, and this brings down the application. I was on half a mind to add the VT_VARIANT conversion to VariantChangeTypeEx() myself, but then I checked the tests for this operation, and it seems that the absence of support for VT_VARIANT is actually expected (unless I am misreading the code). Therefore, one of the following two things is happening: 1) There is some error in the reading of the typelib, since a Property Put should not have a VT_VARIANT parameter in the first place. 2) ITypeInfo::Invoke should do the VT_VARIANT conversion itself, precisely because VariantChangeTypeEx() won't do it. I am inclined to the second option, but I want to hear some comment before attempting to create a patch. Alex Villacís Lasso

That way the parser can deal with the problem. Mike

Looks like FT_Bitmap_Convert is a relatively new function - I don't have it in fc4. You're going to need to provide a fallback or simply ignore it completely and code it yourself.

Start off with a patch that moves FontSubst to using the struct list stuff. Then try sending a patch that uses FT_Sfnt_Name. Thanks, Huw. -- Huw Davies huw(a)codeweavers.com

Dogfood status
by Dan Kegel 15 Mar '06

15 Mar '06

I've been dogfooding Wine with Firefox for some time. It's totally usable and good looking now. The four open bugs, http://bugs.winehq.org/show_bug.cgi?id=4523 (copy/paste problem) http://bugs.winehq.org/show_bug.cgi?id=4528 (too tall) http://bugs.winehq.org/show_bug.cgi?id=4762 (flash crash) http://bugs.winehq.org/show_bug.cgi?id=4829 (jerky animations) while serious, do not prevent me from getting work done. A new problem is that apps have been crashing with X Error of failed request: BadAtom (invalid Atom parameter) Major opcode of failed request: 17 (X_GetAtomName) Atom id in failed request: 0x0 every day. This is on Ubuntu 5.10 with updates, and might be a problem with the X server. I'll try updating to Ubuntu 6.04 flight 5 and see if that makes it go away. Anyway, since Firefox is in fairly good good shape, I'm now running putty under wine instead of using linux's built-in ssh. Works fine. Three annoyances: 1) takes a while (ten seconds) to open up session after clicking 'open'. 2) every keystroke yields the console message fixme:imm:ImmReleaseContext (0xb014e, 0x7fdbee18): stub 3) It took me a while to figure out how to copy and paste in putty, since Linux doesn't have the 'copy / paste' items in the upper left corner menu. (ctrl-insert and shift-insert work fine.) But that's a linux window manager issue, not a wine issue. Overall, I'm productive and happy. Success! Since those are the *only two gui apps I use* on Linux, I'm running out of things to dogfood! Oh, once in a while I need an image editor. Maybe I'll dogfood windows gimp next (quadruple yuck)... - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv

Free mirror for .deb APT repository (forwarded correspondance)
by Scott Ritchie 15 Mar '06

15 Mar '06

Hey guys. For the past few days I've been corresponding with Pieter de Bruijn, who has graciously offered us a huge amount of bandwidth to host the APT repository for our .deb packages, rather than having to put it in the sourceforge webspace where it is rather slow and times out a lot. By my estimates, we get about 800 downloads of Wine from the APT repository per day, which is about 10 gigabytes. All other package downloads from sourceforge combined constitute about 4000 downloads, so roughly 20% of our package downloads are using the APT repository. As for what percentage of our user base uses current .debs, I don't know, because more or less up to date Wine packages derived from mine can be also grabbed from the Ubuntu backports server, the Ubuntu development server, and likely some other place I don't know of. It wouldn't surprise me if over half our users were on Ubuntu at this point, though. One important advantage of Peter's offer is that it allows us much more storage space, possibly including multiple APT repositories for different distributions. This would be far preferable to the ~100 megs or so we get on Sourceforge, which can barely fit one package. Anyway, I'd like to inform everyone about the hosting offer and gather some additional feedback, if you have any comments about the change. Thanks, Scott Ritchie

Updated DDraw over WineD3D patch
by Stefan Dösinger 15 Mar '06

15 Mar '06

Hi, I've uploaded anothe update of my DDraw->WineD3D patch to http://stud4.tuwien.ac.at/~e0526822/. It fixes some refcounting issues and the D3D renderer of the Half-Life 1 Steam version works. It also takes the merged header patches into account ;) I am quite busy the next time, so I won't be able to do a lot ddraw development. I'll continue to send patches, but only header changes, no added functionality. I'll keep myself up to date and anser feedback mails, but I don't think I've the time to do intensive development. I expect I can continue in April. Have fun playing, Stefan
