Readfile on a duplicated pipe hangs
by Uwe Bonnes 10 Jan '03

10 Jan '03

Hallo, Marcus sent me patches that made Altera quartus install. Thanks. Now running the package hangs in the way it communicates with created processes. Here is what happens in my understanding: M: Masterprocess C: Childprocess M: CreatePipe -> handle_read + handle_write M: DuplicateHandle handle_read -> handle_read_dup M: CloseHandle (handle_read) M: Call CreateProcessA with handle_write as hstderr M: Return Createprocess M: CloseHandle (handle_write) M: Call Readfile (handle_read_dup) C: initializes, executes and exit M: Return Readfile retval=00000001 M: Endless loop of Call Readfile (handle_read_dup) retval=00000001 MSDN says, that ReadFile should fail on an anonymous pipe, if the othe end has close. With following patch, the application starts up. Feedback welcome.

Re: widl patch

Indeed, I am doing this now with my RPC test. I'm not sure we are targeting the same stuff, however. You can see my work-in-progress in the K patchseries, which only has one (rejected) "official" patch: K01. Actually, what I'm really trying to do is mix and match. I want the .h header to be generated by widl, and the _s.c and _c.c stubs to be generated by MIDL. wire_marshall should be a barrel of laughs ;) Maybe after I get this batch working I'll whip up some tests for 'ya that use it. I encounter the following gaps: o widl doesn't generate forward declarations for MIDL_user_allocate and MIDL_user_free, should be trivial to fix. o widl doesn't parse the implicit_handle stuff in the .acf, which cause MIDL to put an extern declaration in for the handle. o RpcTry/Except/etc. Ugh, what a $&^@$*% train wreck. More-or-less unfixable, and not widl's fault anyhow. ATM I may hack around this using some evil, incorrect, and, frankly, downright offensive macros. Long term, of course, I'm interested in seeing exception handling souce-compatibility in wine... perhaps, winegcc, or some cousin, could parse VC++ __try & family and generate wine-compatible __TRY & family to match? Given the freedom to parse/generate, regardless of the implementation specifics, it becomes a surmountable problem IMO. Otherwise, it works perfectly. Good work! Any chance either of the first two points will be fixed soon? This would leave me with only one inelegant hack (two if calling MIDL counts), and an otherwise tolerable build process.

Kaleidagraph demo
by Jos van den Oever 10 Jan '03

10 Jan '03

Hello Wine developers, The one program holding back linux adoption in my lab is the application Kaleidgraph. Kaleidagraph is a graphing application that is avaibable for Windows and Macintosh. I've been trying to use Kaleidgraph with wine (wine-20021219) without a windows installation on the computer. The installation works pretty well: Kaleigraph is installed, only the installer does not exit cleanly but not until it asks about displaying the readme file. Running Kaleidagraph does give quite a few problems. The problems seem to arise from bugs and not missing features in wine. One bug for example is, that almost all menu entries are listed twice ("File Edit Gallery ... Windows Edit Gallery ... Windows Help"). I'd like to help in making this program run by testing with the CVS version and submitting bugs. However, I think it would be easier if someone more experienced looks at the program first and irons out the biggest problems, because they are instantly obvious when you try to run the program with wine. There is a demo version of Kaleidagraph that can be downloaded for free from www.kaleidagraph.com. Best regards, Jos

Possible bug?
by Mike Hearn 10 Jan '03

10 Jan '03

Hi, I think this code in menu.c, BOOL WINAPI SetMenuItemInfoA(HMENU hmenu, UINT item, BOOL bypos, const MENUITEMINFOA *lpmii) { if ((lpmii->fType & (MF_HILITE|MF_POPUP)) || (lpmii->fState)) { /* QuickTime does pass invalid data into SetMenuItemInfo. * do some of the checks Windows does. */ WARN("Bad masks for type (0x%08x) or state (0x%08x)\n", lpmii->fType,lpmii->fState ); return FALSE; } .... is buggy, because it checks the type and state even when fMask doesn't indicate that these fields are being used. It was added by Marcus Meissner at LinuxTag in 2001 which is why I'm confused, the bug I'm playing with/learning how to debug with is a regression and didn't exist a few months ago, yet that code has been in Wine for some time. Could somebody more experienced than me please look over the description of the MENUITEMINFO struct: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinU… and the SetMenuItemInfo call: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinU… .. and tell me if I'm reading this situation correctly? I don't think it should be returning false like this when fMask is 6, ie MIIM_ID | MIIM_SUBMENU. It'd only take a minute, promise :) -- Mike Hearn <m.hearn(a)signal.qinetiq.com> QinetiQ - Malvern Technology Center

html browser for wine (khtml)
by Hetz Ben Hamo 10 Jan '03

10 Jan '03

Hi, Yesterday, Apple released their web browser - Safari. The license is LGPL and the code is based on KDE's KHTML rendering engine. Whats the difference? now you don't need QT, so license wise - it's kosher ;) Thanks, Hetz

Or do you have any other suggestions? Compiling stuff with visual studio is a first step. But it should be very simple to do a Makefile for the examples, how many files do you have in one example?
