Subject [jira] [Created] (CXF-5403) wsdl2java generating file names that are too long for encrypted filesystem
Date Wed, 20 Nov 2013 04:37:20 GMT
Andrew created CXF-5403:
---------------------------

             Summary: wsdl2java generating file names that are too long for encrypted filesystem
                 Key: CXF-5403
                 URL: https://issues.apache.org/jira/browse/CXF-5403
             Project: CXF
          Issue Type: Bug
          Components: Tooling
    Affects Versions: 2.7.7
         Environment: Linux Mint 15, EcryptFS
            Reporter: Andrew


When using the CXF Codegen Maven plugin, and the wsdl2java goal, I get the following exception:

{noformat}

The reason for this is that I've encrypted my home directory with EcryptFS, but (unknown to
me at the time) it does not support file names which are longer than 143 characters, and will
not in the foreseeable future (as per https://bugs.launchpad.net/ecryptfs/+bug/344878).

Is there any way to do something about the file name being generated by CXF in this instance?
Surely it doesn't need to duplicate the whole path in the file name? And if it does, wouldn't
it make more sense to hash it and include the hash instead of the path? e.g. a SHA512 hash
would be a fixed 128 characters, plus 5 for the ".DONE" suffix makes 133, which is within
the 143 characters I'm allowed...

That would also guard against the possibility  of the name exceeding 255 characters, which,
while less likely, is still quite possible if you're going to store the whole path in the
file name.

This does mean that I have to be *very* careful about the naming of my projects if I want
to get the WSDL generator to work, which isn't an awful lot of fun.

It's also eating the actual error, as you will note that the exception is above is only being
output at DEBUG level. The actual exception I see when I run mvn -e is:

Which is not particularly helpful.
