ReadFile() question (Bug?)
by Martin Wilck 04 Jan '02

04 Jan '02

Btw, in the code in ReadFile() / WriteFile() handling consoles, shouldn't there be a close (unix_handle) statement before calling ReadConsoleA() / WriteConsoleA() ?

Re: [RFC] cleaner FD_TYPE_XXX implementation
by Mike McCormack 04 Jan '02

04 Jan '02

Hi Martin, Sorry, i should have been a little more clear: if there is a overlapped console, the code in ReadFile (ie. the implemention) will ignore the fact that it is a console, and treat it as a standard overlapped file. In other words, ReadFile should check if the fd is a console fd first, then check if it has the overlapped flag. What you're trying to do is good, and my complaint is just a quibble since the console code doesn't support overlapped operations now anyway :-] Mike Original message from: Martin Wilck <Martin.Wilck(a)fujitsu-siemens.com> > >On Fri, 4 Jan 2002, Mike McCormack wrote: > >> looks good to me.

Hi Martin, looks good to me. The only complication i can see is if overlapped operations are possible on consoles.

Debugger on Solaris
by Robert Lunnon 04 Jan '02

04 Jan '02

I sent this message before but I dont think it reached the list. I am trying to make the debugger work on Solaris. The wineserver and debugger currently co-operate using ptrace to debug a client app, but on solaris the debugger deadlocks. It was previously thought that this was due to the threading model on Solaris which is different. (Different threads don't have different pids). The ptrace manual says that a client must call ptrace(PTRACE_TRACEME...) before it can be debugged but grepping the Wine source can find no useful references to TRACEME. Without calling ptrace (TRACEME,...) Solaris returns ESRCH even though the process exists which causes the wineserver to assume the process is defunct and delete the app, apparently causing the deadlock (This deadlock will have to be fixed too !). Can anyone enlighten me as to what gotchas there are in fixing this since I don't know much about Linux behaviour (Though the linux ptrace mentions PTRACE_TRACEME too but apparently doesn't enforce it !)

This is exactly what everybody seems to assume we don't need: tests that are *known* to fail. (like Ulrich Weigand said: have status variables like FAIL, XFAIL, GOOD, XGOOD) The key to success is to check the *difference* to *expected* behaviour. And if there is indeed a *difference*, then we know that something changed and we need to examine it more closely and thus derive our ultimate result codes from it. Again, we can't just include tests that work on all occasions. Instead we should have tests that are as thorough/strict as possible, and thus with all sorts of failures, but which ultimately don't let the test suite fail, since they're *expected* to currently fail. -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://home.nexgo.de/andi.mohr/

It looks like you try to start the script from directory, which does not have wine.pm module. You need to put contents of the archive to directory "programs/winetest" of the wine source tree, build winetest application, then it will work. This directory should have wine.pm. Because of the problems I reported in the message (see below) the scripts require different launching.

Just looked at the tool. It only provides gateway from Perl to wine API functions, right? Advantages I see in using script-based tests: 1) tests can be used without recompilation 2) Perl is familiar to many developers 3) programming in scripting language is usually easier than in C 4) Perl is widely used for testing purposes and I expect to find many testing tools in Perl. Cons: 1) Many current Wine contributors don't know Perl 2) one more level of abstraction does not give significant advantages in this application. On the contrary, it is more difficult to locate cause of problems because developer has to go trough one more, often not familiar layer. Absense of strict typing in this layer will hurt a lot. Advantages of using C-based tests: 1) compilation has to be used to run the tests. In some cases this is an advantage. Before running the tests you'd better be sure it at least compiles in both environments. 2) C is the most familiar to developers language and the language itself is simpler than Perl 3) Documentation for Win32 API is C-oriented. Examples, given in documentation are in C or easy translated to C 4) Developers already have some testing code snippets in C Summary: Requirements to the unit testing tool: 1) should help to quickly create tests 2) easy to use, should help to involve as many developers as possible. 3) may be useful for developers, using Wine for there projects Because of the goals I'm more inclined to use C-based test suite. IMHO it is better suited for existing Wine developers audience and will provide us much bigger code pool. I'm even ready to have tests in both - Perl and C. The big question is a tool to test GUI. I did not find any OS Windows GUI testing frameworks :-( Comments, suggestions? Thanks, Andriy Palamarchuk __________________________________________________ Do You Yahoo!?

[RFC] cleaner FD_TYPE_XXX implementation
by Martin Wilck 03 Jan '02

03 Jan '02

The FD_TYPE_XXX macros are used in the ReadFile() and WriteFile() routines to invoke special read/write procedures for file descriptors of certain types. I feel that for future improvements of Wine IO, it might be important to distinguish between FD type (regular file, serial port, pipe, ...) and FD attributes (can do overlapped IO, uses timeout, ...). That is the rationale for the following small patch. Please comment.

[Shrinker] Another landmine
by Robert Baruch 03 Jan '02

03 Jan '02

More stepping through the code, comparing Windbg to gdb, and I found another landmine. Shrinker gets the address of the NTDLL procedure LdrAccessResource, and looks for this code: FF74XXXX push [esp+X] E8XXXXXXXX call .... Instead, it finds an unimplemented procedure in Wine. So now I will look at LdrAccessResource (and friends) to see what's involved in implementing it, whatever it is. --Rob

Mixed-mode CD Labels
by Chris Green 02 Jan '02

02 Jan '02

Hi, I've just experimentally, in my own copy of the CVS, changed the code in misc/cdrom.c so that it handles mixed mode CDs the same as data CDs for retrieving CD labels. (In the process of trying to get Age of Empires 1 to run in single-player mode). And surprisingly, it worked! (mind you AOE is not fast under wine, but that's another problem). Does anyone have any comments on this approach? if not I'll submit a patch... regards Chris Green
