File Problems in Perl-Run?

[Jeff Crist]

We recently migrated to modPerl, but only the Perl-Run parser (not
Apache::Registry) to maintain compatibility while I clean up the
scripts.  We are seeing an abnormal behavior when reading files, very
randomly (maybe about 1 out of 20 times) only the first line of the file
is read.  The code looks something like:

open (FILE, $path/$filename);
lines = FILE;
close FILE;

The file contains about 50 lines with each line containing values
separated by commas.  Normally, this routine returns a 50 element array
lines with all the lines in the file.  But sometimes, it just returns a
1 element array with just the first line of the file.  Very strange.
The only thing I can think of is that the old server was FreeBSD and the
new server is Linux.  Not sure if they handle file I/O differently in a
Perl environment but it seems for some reason the script things the end
of file is after the first line sometimes.

Any suggestions, ideas, would be greatly appreciated.

Thanks!

Hmmm.  Something like isn't the sort of thing we like to see here... :)

 open (FILE, $path/$filename);
 lines = FILE;
 close FILE;

Any file locking?

Have you read the Guide?
