Issue1717492

Currently this method always returns false.

I don't see any simple way to implement this on jython; java does not have not support for detecting mounted filesystems. At least that I can find in google or browsing the java 1.4 and 1.5 documentation.

Perhaps the submitter has some pointers on how this can be done in java? 

If it can't be done in java, it can't be done in jython.

Unfortunately I don't have any idea how to implement this in Java/Jython. I submitted this because I noticed following at the top of javapath.py when I was writing patches to abspath and realpath bugs.

# Incompletely implemented:
# islink -- How?
# ismount -- How?
# splitdrive -- How?
# normcase -- How?

There already was a bug report for normcase [1] but I submitted also islink [2] and splitdrive [3]. I also created patches for all other than this one and Charlie has already committed most of them.

If there's no way to get this implemented I'd say simply documenting this is a good enough resolution. Not having ismount in Jython is not that big a problem especially because it doesn't work in Windows either.

there's no way I can see of implementing this on posix. we now use the 
platform dependent path module (ntpath on Windows) as of r4171; ntpath 
actually includes a pure python version of ismount (it's easy to do on 
windows).

we might want to remove this from ntpath though, because people using it 
on windows might expect it to work on posix (since it exists in both 
places on CPython)

ntpath.ismount was disabled in r4174

This functionality will be set aside; Currently this nice to have will
have to be placed on back burner as it don't meet target goals...

ismount is implemented in jython 2.5a2 and later.

Guess this is fixed then.
