<?xml version="1.0" ?> <kc> <title>Wine Traffic</title> <author contact="http://www.theshell.com/~vinn";>Brian Vincent</author> <issue num="181" date="08/01/2003" /> <intro> <p>This is the 181st release of the weekly Wine Weekly News publication. Its main goal is to enjoy getting outside, spending time in the mountains, and splicing hundreds of little wires destroyed by a pick axe. It also serves to inform you of what's going on around Wine. Wine is an open source implementation of the Windows API on top of X and Unix. Think of it as a Windows compatibility layer. Wine does not require Microsoft Windows, as it is a completely alternative implementation consisting of 100% Microsoft-free code, but it can optionally use native system DLLs if they are available.

Unfortunately it's a site I don't have a lot of time to read. I was digging through the archives last weekend and ran across an interesting article about <a href="http://www.securityfocus.com/infocus/1641";>disassembling a Windows trojan</a>. Granted, the article is now nine months old, but it's still very relevant. It goes into great detail on how to use Wine with IDA Pro to disassemble the trojan. After disassembly it shows how to run the code under Wine and debug it with gdb. Oddly enough they don't use Wine's own debugger but the process seems to work for them.</p> </section><section title="Profiling Wine" subject="Profiling wine" archive="http://www.winehq.com/hypermail/wine-devel/2003/07/0690.html"; posts="6" startdate="07/28/2003" enddate="07/29/2003" > <topic>Debugging</topic> <p>Mike Hearn asked a question related to debugging, <quote who="Mike Hearn"> Is there any way to get measurements of where Wine is spending most of its time? I have a problem where typing text into the WebBrowser control is incredibly slow, but don't really have a clue where to start looking. A profiling tool would be handy about now...... </quote></p> <p>Jeremy White replied first:</p> <quote who="Jeremy White"><p> Charles and Mike did a fair amount of work to submit a patch to Wine to enable a profiling mode. </p><p> Sadly, Mike is on vacation this week, so i'm not sure if he's around to help out. </p><p> But if you look through the archives (I think Mike mailed it in), you should find it. </p><p> We'd really like to have other folks using this code... </p></quote> <p>Mike had some questions, but apparently only Mike McCormack would be able to answer him. In lieu of a response about getting that patch into Wine, Lars Segerlund wrote:</p> <quote who="Lars Segerlund"><p> How about giving oprofile a spin ? </p><p> It is very good at pinpointing runtime hotspots. I just wanted to give a suggestion on how to get going with profiling right now without the need to wait for wineprofile functionality. </p></quote> <p>Jeremy wasn't sure how well that would work:</p> <quote who="Jeremy White"><p> I'm told (and have been persuaded of this), that Wine's internal structures preclue a 'normal' profiler from working properly, hence the need for a Wine specific one. </p><p> I know we toyed with adapting gprof to Wine semantics, but decided, in the end, that was too hard and not worth it. </p></quote> <p>Ove Kåven felt oprofile was different and would work. He mentioned a caveat, <quote who="Ove Kaaven"> Then again, oprofile is not a normal profiler, it's a kernel-based one. I've tried it, it "works", but it seems that it requires a 2.5 kernel in order to be really useful (it's not able to generate call graphs with 2.4)</quote></p> </section><section title="Debug Problem With Win98 Version" subject="Is wine a debugger?" archive="http://www.winehq.com/hypermail/wine-devel/2003/07/0639.html"; posts="3" startdate="07/24/2003" enddate="07/28/2003" > <topic>Fixes</topic> <p>Dan Timis needed help with what appeared to be a problem with the Wine debugger:</p> <quote who="Dan Timis"><p> I am trying to load a security Windows dll that does not run under a debugger. When I load the dll I get a SIGTRAP, and then wine breaks in its debugger. </p><p> My understanding is that if I run wine as opposed to winedbg I am not running under a debugger. But, if there is a crash or some other exception wine will start a debugger. </p><p> I sent some memory dumps to the developer of the security dll, and he said that it behaves like it was running under a debugger. He's question was something like does wine have an always "on" debugger? </p></quote> <p>Alex Pasadyn wrote back with a possible solution:</p> <quote who="Alex Pasadyn"><p> I have seen this kind of thing before. I had a program that was doing this, and to get around it I changed the "Windows version" for Wine from one of the "DOS-based" ones to one of the "NT-based" ones. </p><p> This may or may not work for you. It depends on what exactly the program is trying to do to detect a debugger. I just tried setting the version to NT because I figured that the things it allowed were closer to what would be allowed on Linux, and it happened to be that whatever it tried to do on NT gave the "correct" answer on Wine. </p><p> But yes, the Wine debugger loads as a new process only after a crash is detected. What is happening is the program is poking around in memory somewhere and seeing something different from what it expects. </p></quote> <p>Dan tried it and it worked.</p> </section><section title="Testing Controls with Mono" subject="Re: [Mono-winforms-list] SWF Examples/Tests" archive="http://www.winehq.com/hypermail/wine-devel/2003/07/0692.html"; posts="1" startdate="07/28/2003" > <topic>Testing</topic> <topic>Integration</topic> <p>Timothy Parez sent a message to Mono users about some testing he did with the Mono/Wine integration:</p> <quote who="Timothy Parez"><p> Some time ago I started writing simple tests for SWF control rendering. At that time I had no way to manage them, but now Duncan has created a new page on the Mono Wiki where I will add the samples. </p><p> Each sample contains the sourcecode, makefile and screenshots. I will try to create these samples for each of the controls in SWF </p><p> I will however make seperate projects for controls which use images, because these don't seem to run on SWF yet. (For example a button with a background image) </p><p> You can find the wiki page here: <ul><a href="http://www.nullenvoid.com/mono/wiki/index.php/WineSamples";> http://www.nullenvoid.com/mono/wiki/index.php/WineSamples</a></ul> </p></quote> <p>Mike Hearn forwarded that to wine-devel and explained:</p> <quote who="Mike Hearn"><p> This will be really great for Wine also, I'm forwarding this on to the Wine list. We really need tests like this, but AFAIK nobody has ever done them. </p><p> As you can see the Wine widget toolkit does not implement all the features of the MS Windows one (primarily because very few apps actually use them). Nonetheless, adding them should be easy, and it's good to have a reference like this. </p></quote> </section><section title="Library of Microsoft Compression Formats" subject="[libmspack] A library for Microsoft compression formats" archive="http://www.winehq.com/hypermail/wine-devel/2003/07/0667.html"; posts="2" startdate="07/26/2003" > <topic>Integration</topic> <p>Mike Allen wrote in with a pointer to a library under development:</p> <quote who="Mike Allen"><p> I haven't tried this lib but it looks well organized and clean which is rare so check it out or fwd this link to interested parties... <ul><a href="http://www.kyz.uklinux.net/libmspack/";> http://www.kyz.uklinux.net/libmspack/</a></ul></p></quote> <p>Greg Turner agreed that it could be useful.</p> </section></kc>
