winebuild and circular DLL dependencies
by Ove Kaaven 11 Oct '01

Well, can this be done with delayed imports yet? I have a situation here where ole32 imports stuff from rpcrt4 (windows uses delayed imports for that), and rpcrt4 imports stuff from ole32 (again, windows uses delayed imports). It would be nice if I could use the winebuild delayed import mechanism to achieve this, instead of doing it manually with callout tables and stuff... but I suppose winebuild has to be changed to read the .spec files instead of using nm on compiled libraries... anyone working on it?

Well, we do have (almost) best fit, that's the only reason for having multiple free lists. It's just that we probably need more bins sizes to make it really useful. > We just need > to make sure Wine's free block selection routine uses the same strategies > as this allocator, and we'd get exactly the same performance as that > allocator, but without replacing the whole thing and sacrificing the > compatibility we have or introducing new bugs. Well, this depends how easy it is to plug the new allocator in; but if it doesn't require too many changes, it will certainly introduce less bugs than trying to tweak the existing code. Plus all the profiling work has been done already, which would have to be done on the Wine code. -- Alexandre Julliard julliard(a)winehq.com

FIXME:pthread_rwlock_rdlock

Hi, I am running a compiler with wine. There are many fixme message that I can't switch off. What do they mean, is someone working on it, is the problem serious ? Not having them at stdout would be great :-) as the compiler output + wine fixmes get a little confusing...

The code is using the Win95 values now, but there is no reason we couldn't add a few larger values in the HEAP_freeListSizes array, instead of creating a new mechanism. > Despite the workaround, we're still not too pleased with the current > heap allocator.

A new allocator would definitely be a good thing. This one was done the way it is in order to use a compatible memory layout, but it turns out this is not necessary so we could scrap it. -- Alexandre Julliard julliard(a)winehq.com

SHGetSpecialFolderPathA and CSIDL_FOLDER_MASK
by Chris Green 11 Oct '01

11 Oct '01

I've been looking at this function, and I am starting to suspect we have the wrong definition of CSIDL_FOLDER_MASK (currently 0x00ff). What I've been seeing (eg. installing MS Office 97) seems to imply that only the lower 6 bits, rather than 8, are related to the folder, and the others are something else. Does anyone else think that the mask should be 0x003f? regards Chris _________________________________________________________ Do You Yahoo!?

But you want to use new blocks in general. The exception is that you want to avoid using the uncommitted part at the end of the heap, and I agree we could do a special case for that. But it has nothing to do with the size of the block. > I've had a brief look at the code referenced by Adam Moss (found at > http://g.oswego.edu/dl/html/malloc.html) and it looks like it would > be a vast improvement over Wine's current Heap manager.

You may want to look at ptmalloc too, it's supposed to be better at multi-threading (at least to get some ideas, the license is not 100% compatible with ours). -- Alexandre Julliard julliard(a)winehq.com

There are a lot to do for the whole of Apis to work between processes yes, but there is not so much remaining for this kind of installer to work IMO. Gerard

Greetings, Has anyone got Quick Books Pro 2001 and ACT! 2000 to run on wine? In quick books I get this error when it goes to install it: fixme:ole:CoGetClassObject CLSCTX_LOCAL_SERVER not supported! and it says that the set up failed..... in ACT! 2001 I the install stalls out when I have to say what country I am in.... I have to ctrl+alt+F1 and do a killall to get rid of it. Also its not seeing my ethernet connection.... do I need to add anything to the config file to make this work right? I was trying to install IE over the web.... As far as I can tell it doesnt see that im on the network Thanks Nick Hudson
