Hi Eric,

So removing the disk space stuff seems fine.

Regarding which platform this will run on you have:

- removed checks for obsolete windows platforms
- enabled the general test to now run on Solaris
- changed the test that would only run on windows if -extra was specified to now always run on windows

Does that sum it up? The last part makes me wonder when we would run the test with -extra, as we will now always exercise this part on windows.

And are we sure the Solaris issues are no longer a concern? I assume the problem was doing the disk space checks on remote filesystems.

Thanks,
David

Hi David,

To use dirFile.length() == 0 to replace the disk space measurement as
guess the original test tries to prove that there's no extra disk spent
when creating empty folders.

Sorry I don't understand. File.length() says:

public long length()

Returns the length of the file denoted by this abstract pathname. The
return value is unspecified if this pathname denotes a directory.

Where it is required to distinguish an I/O exception from the case
that 0L is returned, or where several attributes of the same file are
required at the same time, then the Files.readAttributes method may be
used.

Returns:
The length, in bytes, of the file denoted by this abstract pathname,
or 0L if the file does not exist. Some operating systems may return 0L
for pathnames denoting system-dependent entities such as devices or
pipes.

----

In this case we verify we have a directory before we do the length()
test, which means the return value from length is unspecified.

So I don't understand how length() is being used here.

Please help to review the fix below for bug **6962637
<http://monaco.us.oracle.com/detail.jsf?cr=6962637> TEST_BUG:
java/io/File/MaxPathLength.java may fail in busy system
http://dl.dropbox.com/u/90659131/fixes/6962637/webrev/index.html

Root cause is the test is not reliable when system is busy, if disk
space is changed by some other program, test can fail. so the fix
is to
check file.length() instead of disk space.

I can not figure out what the original version of the test was doing
with the disk space measurements but I can certainly appreciate that
they could be changing dynamically while the test is running.

But I don't really understand why dirFile is expected to have a zero
length ???
