Re: [Oorexx-devel] Request for help on (Ubuntu) Linux (32- and64-bit)
I might take a look at this, this weekend, if I have time. Unfortunately, the set up required is a deterrring factor. This would seem to be an excellent example of the use of a virtual machine ... with a standard virtual machine with Ubuntu on it, Rony could do the minimum setup (added packages) to recreate the problem, then hand it over to the expert debugger-person. -- This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev ___ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel

Re: [Oorexx-devel] Request for help on (Ubuntu) Linux (32- and64-bit)
Hmmm, taking a quick look at the code and the places where the file
unreadable error can be triggered, I found the following lines in
FileSystem.cpp:
RexxBuffer *SystemInterpreter::readProgram(const char *file_name)
/***/
/* Function: Read a program into a buffer */
/***/
{
FILE*handle; /* open file access handle */
size_t buffersize; /* size of read buffer */
{
handle = fopen(file_name, rb); /* open as a binary file
*/
if (handle == NULL)
{ /* open error? */
return OREF_NULL; /* return nothing
*/
}
if (fileno(handle) == (FOPEN_MAX - 2))
{ /* open error? */
return OREF_NULL; /* return nothing
*/
}
fseek(handle, 0, SEEK_END); /* seek to the file end
*/
buffersize = ftell(handle); /* get the file size
*/
fseek(handle, 0, SEEK_SET); /* seek back to the file
beginning */
}
RexxBuffer *buffer = new_buffer(buffersize); /* get a buffer
object */
ProtectedObject p(buffer);
{
UnsafeBlock releaser;
fread(buffer-getData(), 1, buffersize, handle);
fclose(handle); /* close the file
*/
}
return buffer; /* return the program buffer */
}
I don't understand the purpose of the fileno(handle) == (FOPEN_MAX -
2) test, but that certainly could be the cause of this error. It's
consistent with the fact that this error occurs even if you change the
name of the file. This test appears to be something pulled forward
from the 3.2.0 code, but I don't know of any reason why that should
have been there in the first place.
Given the number of files that the jvm generally has open, it is
certainly conceivable that we're hitting a window where that's true.

Yes, that would be really great!
Maybe the build-machine allows for that already?

Re: [Oorexx-devel] Request for help on (Ubuntu) Linux (32- and64-bit)
Right now the build machine is in a sort of transition state. All the nightly builds are running (with the exception of Win XP) but I need to install a new network card in the new machine before I can start giving access to VMs. I should have the card this week sometime. What version of Ubuntu do you want to test on? I can install 10.04 easily and I have some older versions as well. Let me know and I will istall it and let you know how to access it.

Let me know and I will istall it and let you know how to access it. 32-bit 10.4 would be just fine (that's actually the version I have been working with since yesterday). Many thanks for all of the efforts in advance! Maybe Rick found the possible cause already, which would be just awesome! Again, many thanks to everybody helping! ---rony On 08/16/2010 01:19 PM, Rony G. Flatscher wrote: On 16.08.2010 19:27, Mike Cowlishaw wrote: I might take a look at this, this weekend, if I have time.
