Does it only happen for this specific file upload and does it happen repeatably?
Regarding the line:
s = environ['wsgi.input'].read().decode('latin1')
First off, this is not WSGI compliant. To be compliant with WSGI
specification you must supply a length to read() when it is called on
wsgi.input.
I want you to first off replace that line with:
length = int(environ.get("CONTENT_LENGTH", "0"))
print("LENGTH=%d", length, file=environ["wsgi.errors"])
data = environ['wsgi.input'].read(length)
print("TYPE=%s", type(data), file=environ["wsgi.errors"])
print("DATA=%s", repr(data), file=environ["wsgi.errors"])
s = data.decode("latin1")
print("STRING=%s", repr(s), file=environ["wsgi.errors"])
Then instead of that replace it with:
data = environ['wsgi.input'].read()
print("TYPE=%s", type(data), file=environ["wsgi.errors"])
print("DATA=%s", repr(data), file=environ["wsgi.errors"])
s = data.decode("latin1")
print("STRING=%s", repr(s), file=environ["wsgi.errors"])
Post the output from Apache error logs for both.
This will help narrow down whether problem is in Python with decoding
bytes to latin1 string, or whether there is an issue in mod_wsgi with
calling read() with no argument, which as I said before is outside of
what WSGI specification allows anyway.
