<title>Wine Traffic</title>

<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.   You can find more info at <a href="http://www.winehq.com";>www.winehq.com</a></p> </intro>

<topic>News</topic>
<p>I really like SecurityFocus.  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>

<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 K&#229;ven 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>

<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>

<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>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...

<p>Greg Turner agreed that it could be useful.</p>
