[Bug 10827] New: No input/output after AllocConsole
http://bugs.winehq.org/show_bug.cgi?id=10827 Summary: No input/output after AllocConsole Product: Wine Version: 0.9.50. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-console AssignedTo: wine-bugs(a)winehq.org ReportedBy: reijo.sund(a)helsinki.fi Created an attachment (id=9694) --> (http://bugs.winehq.org/attachment.cgi?id=9694) pro1.c - simple source that demonstrates the AllocConsole problem MSDN library includes sample code for console applications (http://msdn2.microsoft.com/en-us/library/aa263818.aspx). The source is available at: http://www.helsinki.fi/~sund/console_vs6.zip . The source compiles easily with winelib after --cuiexe transformations with winemaker. The first example is about freeing and allocating a new console. These are basic operations that each reasonable console application should perform. The problem with wine is that input and output for console are disabled after a (second) call to AllocConsole. That makes most interactive console applications unusable. The problem can be replicated by running the sample code application with wineconsole, and by selecting the first example from the list. To make even easier replication possible, I have attached a simple source that demonstrates the problem (works smoothly in Windows). I used the following commands to compile the attached source: export LD_LIBRARY_PATH=$WINE/library:$WINE/unicode winegcc -c -I$WINE/include -o pro1.o pro1.c winegcc -L$WINE/dlls -luser32 -lgdi32 -ladvapi32 -lkernel32 -lddraw -ldsound -lwinmm -o pro1.exe pro1.o -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

Smirnov <lich(a)math.spbu.ru> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lich(a)math.spbu.ru --- Comment #1 from Kirill K. Smirnov <lich(a)math.spbu.ru> 2007-12-19 16:00:06 --- MSDN and your example are a bit buggy... AllocConsole modifies standard io handles, so programmer must re-get them using GetStdHandle. (MSDN example updates only OUTPUT, and you forgot to update both of them when you call AllocConsole last time). [Un]fortunately Windows generates new console handles equal to the old ones, so it is very easy to forget to update them. This behaviour is undocumented but widely used. I've send three patches to fix this, two of them are already applied. http://www.winehq.org/pipermail/wine-patches/2007-December/048106.html http://www.winehq.org/pipermail/wine-patches/2007-December/048062.html http://www.winehq.org/pipermail/wine-patches/2007-December/048148.html And the last but not the least: it is dangerous to run console application using 'wineconsole' directly, because it tells system to use predefined io handles (using STARTUPINFO). Applications should be run using 'start' utility. Dangerous to say: $ wineconsole app.exe use instead: $ wine start app.exe -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

It should not be neccessary to use wineconsole or start to run plain old console apps.
Yes, I mean 'wine start' is supposed to be used with complicated (which use AllocConsole/FreeConsole and screen buffers) applications ONLY. Just 'wine a.exe' is enough for simple apps. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
