[Oorexx-devel] Fwd: [Oorexx-bugs] [ oorexx-Bugs-2779503 ] ooRexx 4.0: RexxShutdownAPI missing from rxapi.dll
I'm not too sure what do with this one. There are a number of APIs that have basically no meaning at all in the 4.0 world, and this is one of them. There are others such as RexxTerminate() and RexxWaitForTermination() that were part of the documented APIs. These have been now stubbed off and are nops and are documented as deprecated. The line in the sand we've drawn so far has been to support documented APIs, but if you've used undocumented ones, well, tough. RexxShutdown() falls into the undocumented category. It would be trivial to stub it out and make it a NOP, but there are lots of other undocumented bits that can't really work that way and there will be absolutely no attempt to get them working in 4.0. My gut feeling is we should say no to this requested, but I'm willing to go with whatever the consensus is.

[Oorexx-devel] Bizarre Windows I/O problems with the 4.0 beta.
We now have two problems showing up in the 4.0 beta that can only be classified as beyond bizarre and both seem to point to problems with the _read() function in the C runtime library. I'm not sure I have any good solutions at this point. In 3.2.0, the stream library was implemented using the higher-level stdio functions. A fairly large amount of the stream library was devoted to getting around differences in the different system and essentially using the stdio functions as if they were the low level IO routines in the first place. In 4.0, each platform provides a SysFile class that encapsulates the I/O functions and provides many of the functions of C runtime higher level I/O routines, but in a fashion that is more tightly tuned to ooRexx's needs. All I/O access is done using the low-level functions (open() vs. fopen(), read() rather than fread(), etc.). Both problem give the symptom that the _read() function appears to be picking up data from someplace other than the opened data stream. I have tried all sorts of solutions to this, but in the end, it all boils down to this should work. I'm not sure where to go from here. One potential solution would be to go native and try bypassing the C runtime functions and use the Native Windows APIs in the SysFile implementation. This is not too terribly hard to do (I think), though performing the mappings for things like open will be a bit of a pain to implement. I have a sandbox branch already where I sort of started doing this, but have generally been tied up with other fixes to make much progress with it. I'm hesitant to really go this route for a couple of reasons. 1) What do we do if it doesn't fix the problems, and 2) This is a fairly big change to introduce in the beta. But then, we might not really have much choice. Note that going back to the old stream library is definitely not an option. That had some serious issues of its own, and would still need to be completely reworked for the new APIs and 64-bit support. That would be an even larger change than bypassing the C runtime (and would impact the unix systems as well as Windows). Anybody else have any ideas on how to approach this? Moving to a dynamically linked C runtime looks like a dead end for a lot of reasons. I wish I could figure out what the root cause for these problems.

Re: [Oorexx-devel] New ::Constant Directive
Thanks Rick. Glad I didn't miss something here. BTW, I used the 'forward' to limit the appearance of the value to a single spot, even though it incurs a performance hit. Next question: are there any good examples of using the .package and .routine classes? I'm a bit fuzzy as to when I would use them. I suspect there are testunits - haven't had time to wade through SVN looking for them - but do they show where one might use these classes as opposed to the mechanics of how they work?

Re: [Oorexx-devel] Bizarre Windows I/O problems with the 4.0 beta.
Just a very quick response to this question (I have to drop offline in 5 minutes) ... I remember from ages ago (1980s) having trouble using the low-level routines in DOS and Windows (and OS/2). The same *sort* of things that we have been seeing .. multithread, perhaps, just weird things. So now my C code (unless it's very old) always uses fread, etc. read() and _read() might have very different characteristics .. seem to have been burned by something like that in the past, too. Maybe not much help ... sorry.

Re: [Oorexx-devel] New ::Constant Directive
Well, routines are really useful to for passing around function pointers or doing dynamic calls. For example, the old problem of doing a variable based functions. For example, ::method init expose variableRoutines // create a directory with the set of locally defined routines variableRoutines = .context~package~routines ::method callit expose variableRoutines use arg functionName say variableRoutines[functionName]~callWith(arg(2, 'A')) The package class allows you to examine/access code for your own or other packages. Some useful functions include what is essentially equivalent to a conditional ::requires or conditionally load native libraries to see if they're available.

Re: [Oorexx-devel] Bizarre Windows I/O problems with the 4.0 beta.
Rick, I'm not going to do this in line cause I'm still thinking about it a little. No option looks good this late in the beta, and it's really not clear which would be the easiest and most likely to fix the problem. I take it the second instance is Walter's bug. Do you have a set up that reproduces it reliably? One other option, is to try building with VC++ 2003 and / or VC++ 2008. I have both Visual Studios. I think both of them will have a different CRT, maybe only slightly different. I don't know how much change there is between versions, but there is some. I try ever day and haven't once seen what Mike reported. But, if Walter's bug is reproducible, I can try building with some different compiler versions. Other than that, going with the Windows native API seems like something we may have to try. Back to Walter's bug, does that come from reading from the console, or is it reading from a file? Windows has always had problems with its low-level console implementation being so much different than the Unix implementation. Which was one reason it was so hard to port Unix applications to Windows. Also, I have been searching for any references to similar problems in Windows. One thing I did come up with is people talking about flushing the keyboard buffer when an application started up. Reports of the buffer having garbage in it even though it was a new process starting up. That would only apply if it was always the first read from the console that had the problem. And I didn't think that was the case with Mike's problem. -- Mark Miesfeld -- Crystal Reports #45; New Free Runtime and 30 Day Trial Check out the new simplified licensign option that enables unlimited royalty#45;free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel

Do you have a set up that reproduces it reliably? I've not been able to reproduce at all. Walter can reproduce it reliably, and Rony has also been able to reproduce. So far, these problems appear to be mostly a European thing :-) One other option, is to try building with VC++ 2003 and / or VC++ 2008. I have both Visual Studios. I think both of them will have a different CRT, maybe only slightly different. I don't know how much change there is between versions, but there is some.

But, if Walter's bug is reproducible, I can try building with some different compiler versions. I've not been able to reproduce Mike's problem in some time, but I was able to get enough information from the times I could reproduce it to determine that the bogus character was getting returned directly from the _read() function. Other than that, going with the Windows native API seems like something we may have to try. Back to Walter's bug, does that come from reading from the console, or is it reading from a file? Windows has always had problems with its low-level console implementation being so much different than the Unix implementation. Which was one reason it was so hard to port Unix applications to Windows. This one is from reading a file. He redirects the dir command to a file twice (same file). When he tries to read this the second time, it appears as if read() is still reading from the first file, but the first few characters of the file are corrupt. And it works for me without error :-( Also, I have been searching for any references to similar problems in Windows. One thing I did come up with is people talking about flushing the keyboard buffer when an application started up. Reports of the buffer having garbage in it even though it was a new process starting up. That would only apply if it was always the first read from the console that had the problem. And I didn't think that was the case with Mike's problem. It was the case in the situation where I was able to reproduce this. It's almost like there are multiple active buffers and the function is getting confused on which one to use. Do you know that they used to flush this? _fflush() and _flushall() are stdio routines, not lowlevel I/O routines. The only lowlevel routine I found was _commit() which was not happy when I attempted to use that on any stream!

[Oorexx-devel] Problem with ::requires 'BSF4Rexx' library
Reworking the BSF4Rexx dynamic library, and in a first step defining a
RexxPackEntry using a RexxRoutineEntry with 13 entries of type
REXX_CLASSIC_ROUTINE only can be compiled and be used with the
RxFuncAdd() function. (There are no new type routines defined in the
source file yet.)
However, using
::requires BSF4Rexx library
causes an exception in the Open Object Rexx Interface.
I tried to isolate the problem and create a simple stand-alone testcase,
but unfortunately I cannot re-create that problem there.
One solution would be to upload the current set of files with a bug
report via the tracker, if deemed necessary.
Otherwise, this is what I can excerpt that relates to the definitions in
case that is sufficient already:
// External functions if loaded via Rexx
// Build the list of entry points for the routines:
RexxRoutineEntry bsf_external_functions[] =
{
REXX_CLASSIC_ROUTINE( BSF , BSF
),

Re: [Oorexx-devel] Problem with ::requires 'BSF4Rexx' library
I don't spot anything obviously wrong here, so you'll probably need to
upload everything. Alternatively, since I know you occasionally build
from source, try running this in the debugger and attach a stack trace
to the bug report.

Reworking the BSF4Rexx dynamic library, and in a first step defining a

REXX_CLASSIC_ROUTINE only can be compiled and be used with the RxFuncAdd()

However, using
::requires BSF4Rexx library
causes an exception in the Open Object Rexx Interface.
I tried to isolate the problem and create a simple stand-alone testcase, but
unfortunately I cannot re-create that problem there.
One solution would be to upload the current set of files with a bug report
via the tracker, if deemed necessary.
Otherwise, this is what I can excerpt that relates to the definitions in

Assuming you have visual studio and you have a Rexx command that creates the problem, just type devenv /debugexe rexx yada yada yada Hit PF5 to run, and it should stop at the location of the trap.

Thanks a lot for the hint of how to use Visual Studio to debug, which I
obviously will need (will have to continue tomorrow evening, though,
already too late and have to get up very early).
