Subject Re: Large data stream caching - Causing Truncated Response
Date Wed, 30 Apr 2014 17:27:21 GMT

We’ve been calling canWrite() on the File object representing the directory for a long time,
so I’m a bit surprised.  I guess in your case, it is writable, but there isn’t space.

I’ve just added a couple more checks in there.  First, if there is less than 1MB of “usable
space” (File.getUsableSpace()) it will now log a warning.   Next, instead of looping indefinitely
trying to create a new directory, we’ll just make 10000 attempts (which seems high, but
should be fairly quick) and if that fails, throw an exception.

That said, with CXF 3.0, this particular case (Logging interceptors) wouldn’t result in
anything being buffered on disk as the default for the caching is raised to 128K and default
for message size logged is reduced to 32K and the interceptors have been further optimized
to only load the 32K needed for logging.
