Dear all,
I do not think that removing Windows specific code is a good idea.
Some time ago I showed as example how many people have downloaded
]project-open[ on Windows as opposed to the VM, or the tar ball.
In case you do not remember the numbers, please have a look at this URL:
http://sourceforge.net/projects/project-open/files/project-open/
The idea of using some kind of emulation is also questionable. Why?
Suppose we want to have Aolserver on Windows , then the emulation layer
would impose unacceptable inefficiencies. Here we are not talking about
using some emulation layer to run some ancillary programs, called every now
and then (e.g. dot, wget, and so on), but Aolserver itself (i.e. nsd), the
very heart of every OpenACS based web application.
The same type or reasoning applies to the database engine (e.g. postgresql),
it would be a major error running it on some emulation layer.
What is the current status of these emulation layers?
I know everybody is thinking about Cygwin... But Cygwin is, at the time
being only a Win32 application.
Nowadays all the servers are 64 bit machines. Soon the same will be for
desktop and laptop computers. With Cygwin on 64 bit Windows machine we have
double emulation:
Linux/Unix Application
-----------------------------
Cygwin/ Posix emulation
-----------------------------
WOW64/ Win32 emulation (this is Windows 32 emulated on Windows 64)
-----------------------------
Windows 64
I cant see any sign of Cygwin moving towards Windows 64. Last year in
summer there was an interesting discussion about that
(http://thread.gmane.org/gmane.os.cygwin.devel/233/focus=247) but nothing
happened because the effort is too big and nobody had enough energy to spend
on it.
For how long will WOW64 be supported by Microsoft? It is already an option
in the core part of Windows Server 2008 R2
(http://msdn.microsoft.com/en-us/library/dd371790%28v=vs.85%29.aspx).
MingGW can now compile for Windows 64 but it lacks the Posix emulation
available in Cygwin.
Another (kind of emulation) solution would be compiling Aolserver with
Visual Studio 2010 (or 2012) + SUA SDK (Utilities and SDK for Subsystem for
UNIX-based Applications) (these two build both in 32 and 64). I am sure very
few people know about this possibility.
So what are the feasible options?
I believe there are only two (well three) options:
1. we maintain the Windows code inside Aolserver (I favour this)
2. we compile Unix only code via the SUA SDK
3. we forget about Windows and we use real emulation, that is a VM running
Linux
But how many people are willing to download a VM of 1.5 GB or so just to
test a system?
A Windows installer of 150MB or so is much, much more attractive. Later on,
if they are happy with the system, people can stick to Windows or use Linux
for production.
What do you think?

Hi!
I've cleaned up our websockets code a bit (ah, the joy of it), it should run
now on a basic AOLserver install. Where should I post it?
