The lib/file/compare.t test has never been correct for VMS, but the bugs where mostly hidden until testing on a ODS-5 volume with that allows filenames with more characters in them than VMS traditionally allows. This is known as EFS_CHARSET mode. This also exposes that the vmsify() routine in the traditional VMS mode is not matching how the C library in VMS internally implements the equivalent function. I am not sure that we want to change the vmsify() function traditional VMS mode behavior at this time. It also exposes that the flush() operation is a no-op on the VMS platform, which is something that needs to be fixed. This issue with flush() has shown up before, but the test was modified to not use that algorithm. The DECC$FILE_SHARING feature needs to be active for this test to work when the EFS_CHARSET mode is on. By default DECC$FILE_SHARING is off, and so far none of the other Perl tests need it enabled, even when in UNIX compatible mode. This patch fixes the lib/file/compare.t test to actually work the way it was intended to on VMS when VMS is in the traditional mode, and not leave extra files behind in SYS$SCRATCH: On VMS SYS$SCRATCH: by default behaves like a user private copy of /tmp on Unix. This patch also adds diagnostics so that explains what is wrong when VMS is run in the EFS_CHARSET mode. As DECC$FILE_SHARING is not normally active, it has a check to skip the tests that require it. The last e-mail from Craig that I saw about the initial submission where he was not sure about the extra diagnostics, but was going to look it over, and I did not see a response to my more detailed post about patch and why these diagnostics are needed.
