Backwards typeahead

Backwards typeahead

[Steve Chapel]

With the cygwin 1.3.13 bash shell running in a Windows 98 SE DOS window, 
I've experienced that characters I've typed in while a command is 
running appear reversed when the command prompt appears again. I found 
this thread <http://sources.redhat.com/ml/cygwin/2001-04/msg01362.html> 
from April 2001 on this subject and wondered if there is any more 
information on this problem. If not, I can look into debugging the 
problem myself, although I'll need a lot of help getting started.

Thanks,
Steve Chapel

I've been told that the backwards typeahead is due to a bug in the OS. 
When the system is overloaded, keystroke interrupts are stacked up. When 
the interrupts are popped off the stack, the keystrokes are recognized 
in the reverse order they were typed.

Although I fully accept this explanation, it avoids the problem with 
cygwin. In a DOS command prompt a dir command takes less than one second 
even if there are hundreds of files listed. In a 4DOS command prompt the 
DJGPP command ls takes a similar amount of time. But in a cygwin bash 
shell an ls command takes three seconds even with only a handful of 
files, and it overloads the system so much that interrupts need to be 
stacked.

So again I ask for information on how this cygwin problem can be solved. 
It makes typeahead completely useless for me.

Thanks,
Steve Chapel

What kind of information are you hoping for?  If we knew how to solve the
problem it would be solved.

I saw on another post that what was needed to fix the problem is someone 
who can reproduce it and is willing to use gdb to track down the 
problem. I just volunteered. Was the earlier post incorrect?

Without knowing what "the earlier post" might be, that's rather hard to say.

Is there a tool to use .dsp files for make?

[J. Scott Edwards]

Hello,

I appologize for the somewhat off topic post.  I have been using Cygwin
for my development on projects in the past.  On the projects in the past
we have had both .dsp files for programmers who use Visual Studio and
Makefiles for programmers who didn't.  Of course there was some occasional
grief when one of them got out of sync.  But on the new project the people
in charge have decided that we will only have .dsp files and everybody has
to use Visual Studio.

Does anyone know of a tool which can either just do what make does from a
.dsp file or convert a .dsp file to a makefile?  I have looked through the
.dsp files and it doesn't look horribly difficult, but then everything
looks easy until you actually try to do it ;)

Thanks
  -Scott

I don't actually use it myself, but...

Google on dsw2mak:

OK. How about http://sources.redhat.com/ml/cygwin/2001-04/msg01486.html
That's a specific post from the specific thread I mentioned in my first 
post.

Ok.  Yes.  If it isn't obvious, then I'll repeat it.  You do need to debug
things to figure out what's wrong.  Sorry for not reading the thread that
you provided to figure out that I agreed with myself.

What this has to do with your request for information still remains a
mystery.  If you are asking for help learning how to debug things then
you probably should be as explicit as possible.

I'm not volunteering to help in this regard, but maybe someone else will.

Have a look at CMake www.cmake.org.
Basically, you create a simple input format that cmake then
turns into a makefile or a dsp file, or a .NET project file.

That worked great!  Well, I had to edit the Makefiles a bit because it
didn't recognize our compiler, but other than that it seemed to work fine.

I kept searching for the project files, it never occurred to me to search
for workspace files.

Thanks!!

Re: Is there a tool to use .dsp files for make?

I used CMake a few years ago on a project (I had no idea it could create a
.dsp file).  But I don't think I would ever sell that idea.  Most of the
people here are firmly commited to working in Visual Studio and don't want
to deal with anything else.  They didn't seem to be too excited this
morning when I was using the Makefile that dsw2mak created to do my builds
;)

But thanks anyway, I will keep the CMake thing in mind for other tasks.

There IS a bug in certain versions of Windows wherein fast type-ahead that
occurs while the system is busy will be queued up in the incorrect order.
What I do not know is if it has ever been fixed, and if so in what version.
I know it exists in 95 (and probably its derivatives). It's documented in
the Kermit-95 pages at columbia.edu as a windows bug.
