Cabextract offered to WINE under LGPL..
by Ender Nov. 8, 2002

Nov. 8, 2002

There you go, now who wants to look into merging cabextract with WINE? [http://www.kyz.uklinux.net/cabextract.php3] It'll be useful for at least three things: - Remove external dependency in urlmon (dlls/urlmon/umon.c) - Implement advapi32:ExtractFiles and fix dlls/setupapi/queue.c - Implement cabinet.dll - Probably some other misc cabinet functions here and there - CHM viewer (in the future) I don't think it would be too hard to merge the 0.7 changes into any merging work done with 0.6, so I wouldn't think it necessary to hold out until then. The only major bug he mentions is fixed by simply changing scope of a variable, so.... :) - Ender ---------- Forwarded message ---------- Date: Wed, 06 Nov 2002 12:37:51 +0000 From: Stuart Caie <kyzer(a)4u.net> To: "J.Brown (Ender/Amigo)" <ender(a)enderboi.com> Subject: Re: cabextract licensing Hello J.Brown On 01-Nov-02, you wrote: > Quick question - would it be possible for you to release/give permission > to use the cabextract code under the LGPL?

Sure, I donate to the WINE project the current cabextract 0.6 code (and next release, 0.7, when it is out) for all uses under the LGPL. Just a few technical things: - as it says in the code, cabextract is not a library. It doesn't bother freeing memory except for the 2MB LZX/QTM windows between folders. You'll have to handle memory freeing yourself :) - further, there is a real bug in 0.6: when an LZX or QTM folder follows a ZIP folder, the LZX(window) and QTM(window) pointer in the methods union will be muddied by ZIP state data and will be non-zero and therefore assumed to be valid window pointers. They're not (they're random ZIP state), so it segfaults. To fix this now, remove the "window" field from LZXstate and QTMstate, and put it in the general decomp_state, then change all references of LZX(window) and QTM(window) to CAB(window). - there are also some minor bugs that you'll see fixed in 0.7 (which is why I gifted you this one as well) If you have any other questions, feel free to ask!

Some dead links on winehq
by Martin Wilck Nov. 8, 2002

Nov. 8, 2002

A small contribution to the winehq fixes: A list of dead or non-functional links on the Development/References page. (http://www.winehq.com/development/index.php?refs) Wine Wine API - mostly useless, IMHO (is this really up-to-date? - at least it shouldn't be on top of the page). Vintage wine sources - ftpsearch.ntnu.no unfortunately out of service. Win32 Win32 API intro - dead WinDoc - only the "Local Mirror" works, the "at microsoft.com" links bring you to the main MSDN site. Unix Unix98 - needs registration LinuxThreads - why is this linked here? AFAIK not used by wine anyway. X The motif zone - dead lamentation - dead Fonts Internet Font archive - gone. X11R6 fonts - dead t1lib -dead Curvesoft - have ceased operations, a few tools still available. x86 Assembly Intel Documentation - dead Writings on software development Homesteading the Noosphere - dead Lisp... - I don't know why it's there, but I love it :-) The Open Source-revolution - dead Martin -- Martin Wilck Phone: +49 5251 8 15113 Fujitsu Siemens Computers Fax: +49 5251 8 20409 Heinz-Nixdorf-Ring 1 mailto:Martin.Wilck(a)Fujitsu-Siemens.com D-33106 Paderborn http://www.fujitsu-siemens.com/primergy

My app calls GetCurrentObject with a valid HDC and OBJ_BITMAP. It returns 0, however, which causes my app to crash. What further info can I provide to help debug this? -Steve

Re: wine button
by Scott Pickett Nov. 8, 2002

Nov. 8, 2002

I think the idea of the button is great! I think you need to rework the graphic. (1) It's too big. Software publishers would view it as a small additional message about their product. As such, it should be less than half that size. (2) Put "Linux" in the message. It will make it clearer to the windows-user audience and be considered more valuable to the software publisher. "Linux/Wine Certified" or "Runs on Linux+Wine" or some such thing. (3) I'm not knocked out about the graphic, but I'm not artistic, so I don't know why. 3-D shadows, rounded corners, non-white background??? It just doesn't grab me, as is. I think the basic idea is great, however. Scott Pickett Street Wizard Mapping Software __________________________________________________ Do you Yahoo!?

notepad and richedit - why?
by Shachar Shemesh Nov. 8, 2002

Nov. 8, 2002

Hi, I was going over the notepad code, and it is implemented using richedit. My question is - why? There is no functionality there that is not also available through the usual Edit control. The Windows notepad is notoriously implemented via the edit control. Is there a special reason why our notepad is different here? Shachar
