[Oorexx-devel] Experimenting security checks option
After reading this MSDN article http://msdn.microsoft.com/en-us/library/aa289171.aspx I decided to test these options, and modified orxwin32mak like that (added security_check) : !IF "$(NODEBUG)" == "1" security_check = /GS ... !ELSE security_check = /GS /RTCc /RTCs /RTCu ... !ENDIF cflags_common=/EHsc /nologo /D:_X86_ /DWIN32 $(VER_DEF) $(WARNING_FLAGS) -c $(my_cdebug) $(security_check) $(MK_ASM) $(RXDBG) /DNULL=0 I had my first security error when running the base\class\string testsuite, but it can be ignored : it's because of the /RTCc option which makes the runtime complain when casting to (char) in encodeBase64. I bypassed the errors by and-ing with 0xFF, as explained in the error message. The rest of the tests in base\class pass without error, including Stream.testGroup (I saw Ricks'call for test cases, I will try to write some, but probably not before next WE). concurency : ok directives : ok expressions : ok keyword : ok rexxutil : KO The second security error ocurs when running SysDriveMap.testGroup. The fifth and sixth call to SysDriveMap raises this error : "Run-Time Check Failure #2 - Stack around the variable 'DeviceName' was corrupted" In both cases, the call is self~assertNotNull(SysDriveMap(,'local')) I can't find what's wrong with these two calls, and maybe I loose my time for nothing, but... runtime.objects : ok source.file : ok special.variables : ok No security error when running Mike's getc.rex script...

I Please do so folks. Don't worry about duplicating something I am doing. The test suite currently only takes a few minutes to run to completion with something like 16,000 tests. If 10 people out there each wrote 100 test cases that were similar to something I did, we'd just add them in and probably add less than 60 seconds to the total run time. Plus, similar is not the same. Most likely each test case would generate a slightly different code path.

[Oorexx-devel] We desperately need some I/O test cases.
I just fixed a crash in the stream class "query datetime" function on windows that would never have gotten through if we had anything resembling a regression suite for the I/O functions and class. We really need at least some minimal tests for all of the various functions, plus we need to have some tests for the different open options (NOBUFFER, APPEND, etc.). How about it folks, any volunteers out there willing to write some test cases for a problem area? I'm almost in favor of not shipping the final 4.0 version until we have a good regression suite, so the more hands we have helping with this, the more likely we might hit our end of May target for the beta.

Good thing I said "seems to be." I was 100% wrong on this, it was not the compiler at all but the programmers. ReadFile() takes a pointer to a 32-bit value to return actual count of bytes read. In the code clean up / move to 64-bit / conversion to the new API, the variable was changed to a size_t. In ReadFile() the variable was cast as a pointer to a 32-bit variable. Well, that's no good on 64-bit Windows. Anyhow, sorry I blamed the compiler, it wasn't a compiler bug at all. -- Mark Miesfeld -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensign option that enables unlimited royalty-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

Yes, this is pretty much the 'worst nightmare' bug .. probably someone else's fault, cannot be easily reproduced, but all too obvious when it happens (and can have weird side-effects, when the change to an 'r' meant an old program I hadn't run in 10+ years and had completely forgotten about got run and sent off an e-mail to an old acquaintance ...). > I do have a questions for you Mike.

No. Most often it is the first command in a new command window, but it also happens later. I thought for a while that it happened more often with commands starting with 'c' but no longer think that is the case. I also thought that perhaps it needed two command windows open .. but again, the case today was definitely the only command window open (because if I have one left open during reinstall the install process alerts), and it was the first Rexx program run after re-installing ooRexx.

I know exactly what you mean. The first few times I saw the error 'RAY' is not recognized as an internal or external command, operable program or batch file. I thought I'd just mistyped something. I don't even have any theories on how/why this is happenng based on the symptoms we're seeing. I have enough debug evidence from the times I have been able to reproduce this to be very certain the bad character is coming directly from the CRT _read() function. At least in my situation, everything was single threaded. I do have a questions for you Mike. I've only ever seen this on a first read. Have you ever seen the overlay occur in any place other than the first character or a line? Have you noticed any pattern as to things you might have done *before* the command with the overlay? Mark, you might want to spin a new install package from the sandbox. I've fixed the query size/query datetime problems for directories.

It's starting to look like upgrading to VS 2008 might be a winner for
this. I'm more willing to make this change than switch to the new
version of SysFile. Can the two version coexist on the same machine,
or do I need to uninstall 2005 first?

Re: [Oorexx-devel] Questions ad an object being used by a different RexxInstance ...
I'm not sure this question makes any sense. An interaction on an object occurrs in the context of where the interaction is triggered. Objects are just data, and have no knowledge of where they have been created. If one instance stores an object in .environment (generally a bad practice), then it is just an object that's available for any instance. It will remain alive until the global Rexx environment is terminated. Rick On Sun, Apr 26, 2009 at 6:32 AM, Rony G.

Re: [Oorexx-devel] Tracked down problem with: compiler, Vista, ?
This looks like a classic optimizer bug to me. For some reason, the
code generator has obviously decided it can used a cached version of
the data pointer for the if test rather than reloadingbut it
appears to make that decision only for the if test. It might be
interesting to try declaring that value as volatile and see if things
change.

[Oorexx-devel] Questions ad an object being used by a different RexxInstance ...
Given two different RexxInstances R1 and R2 running in the same process. In R1 an object O1 is created and saved in ".environment". Two questions ad RexxInterpreter context: 1. If from R2 an interaction occurs with O1 (addressed via ".environment"), in which context does O1 execute, in R1 (the creator RexxInterpreterInstance) or in R2 (the invoker RexxInterpreterInstance)? 2. If R1 is terminated, but R2 interacts with O1 (addressed via ".environment"), in which context does O1 execute, in R1 (the creating RexxInterpreterInstance, but terminated) or in R2 (the invoking RexxInterpreterInstance)? ---rony -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensign option that enables unlimited royalty-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
Re: [Oorexx-devel] Tracked down problem with: compiler, Vista, ?
Interesting ... would be interesting to see the asm generated in the
good/bad cases (/FAs option, I think)...
Only 64-bit Vista is a bit strange though (I'm on Vista 32, and Rick also
saw the problem on XP).
However, I think you may well be right about something bad in the 2005
compiler or libraries -- ran with the 2008 version for Friday evening, all
of yesterday, and a hour or so this morning -- no pesky 'r' seen.
Will switch to Rick's new version later this morning.
