Hi
Can't seem to get Andrea Cini's euwingui working with 4 - get a machine level exception with
handle = machine_func(51, {dll, name, args, 0})
and when replaced with
handle = define_c_proc(dll, name, args)
get machine level exceptions elsewhere (first call to dll as far as I can tell, vars = c_func(getglobalvars,{}) )
Andrea doesn't seem to have registered here, and its quite a useful little lib, so I was wondering if anyone had got it working, or if Andrea was still about.

Whoa. That's the first time I've ever seen that. Seriously, on the define_c call? Can you run under the watcom [windowed] debugger using a debug build of euphoria? I'll try to get around to doing this, but it may be a while before I get a chance.

It looks like EuWinGui passes euphoria objects to its dll, the back end definition of which have changed. I think it will require the dll to be re-translated for 4.0.

Or, I suppose it would be possible to write a shim that converted any returned values from the dll into 4.0 objects. Obviously, it would slow things down, but at least it should allow old code like that to work.
4.0 objects passed to 3.1 code should be fine (I think). But you'd need to convert anything coming from 3.1 code to be a 4.0 object.

Hi
Purely for curiosity's sake, please explain. How have they changed? How would you one write a shim that would convert? What would they convert - from / to? Has the internal structure / arrangement of the sequence changed from 3.x to 4?

Chris
The biggest change was the addition of the cleanup_ptr at the end of every structure (s1 [for sequences], d [for atoms], etc) used internally by euphoria to represent non-integer types. The code checks to see if this is NULL or not, and if not it attempts to interpret the value as an euphoria routine and calls it (runs the code of the routine). So if a 3.1 object was passed, we'd try to read pass the end of the memory for the structure. And then execute it. (But this particular issue is easy to deal with, a shim just needs add NULL to the end of the structure.)

Yes, when callbacks were made to work with DEP, for some reason the code to do so was written in the include file rather than the back end. I don't know why, but it should probably be considered a bug, and the code converted to C.
Due to the way that eu.ex handles callbacks, it doesn't work with windows callbacks any more. We need to get back to the state where the include file is a simple wrapper around the back end implementation.

Chris
The biggest change was the addition of the cleanup_ptr at the end of every structure (s1 [for sequences], d [for atoms], etc) used internally by euphoria to represent non-integer types. The code checks to see if this is NULL or not, and if not it attempts to interpret the value as an euphoria routine and calls it (runs the code of the routine). So if a 3.1 object was passed, we'd try to read pass the end of the memory for the structure. And then execute it. (But this particular issue is easy to deal with, a shim just needs add NULL to the end of the structure.)
It might not have been as easy as I thought. I wrote the following shim code, but EuWinGUI no longer crashes but doesn't seem to work either.
I realized that it was possible to write the shim layer in 100% Eu instead of in C. This was significantly easier to get working, and wokred out of the box on the first try.
You can get it at http://malcom.unkmar.com/lostsouls/euconvert.zip - euconvert.dll and euconvertinc.e are what you want.
euconvert.e is the source of euconvert.dll, and I also left the watcom build artifacts in (just in case someone needs to rebuild with a different version of watcom or wants to hack the C layer for some reason).

I see what happened. I forgot to mention that you have to manually edit EuWinGUI.ew and replace all c_proc/c_func calls with v3_c_proc/v3_c_func (which goes through the v311 shim compatibility layer).

There's a bug in the wrapper. The return values of v3_c_func() are passed in from a memory block allocated by 3.1.1 code, but after this is turned back into a 4.0 object, the block of RAM is never freed.

I tried compiling euconvert.e by
euc -dll euconvert.e
(having set the environment variables for Watcom and so on), it seemed to compile ok, but I don't seem to have a functioning dll. Just to check, could you compile it for me, I'll see if that works, and do I need to be doing anything special to compile it?

I thought I had replied to this earlier, but it seems not.
Anyways, it's hard to say for sure, but my best guess is that you built the converter dll with 4.0 instead of 3.1.1. In order to work properly, the converter dll must be built with 3.1.1 - otherwise, you get the same issues with struct changes that you would with using 4.0 directly to pass the data in (since that's exactly what a 4.0-built converter dll would be doing).
I considered a C-shim layer (which would get rid of the dependency on 3.1.1) but it was just easier and faster to do stuff with Eu.
