[Fedora-suds-list] Schema Unavailable

[Sean DiZazzo]

Hi,

It looks to me as if the caching system in version 0.4.0 is broken, and any
code run is reaching out to www.w3.org for the xsd files on every execution.

cache.get() returns a string, but when it is used in DocumentReader.open()
it expects a parsed sax object.

Without debugging on, it fails quietly and creates a zero length cache file.
 Then when it tries to use the zero-byte cache it fails with a cryptic
message.

If you need a patch, please let me know.

Once that was fixed, I was able to turn on caching in my script and get
around the problem of www.w3.org not giving up the xsd documents in a timely
manner.
