Pedro Lamarão created HTTPCORE-635:
--------------------------------------
Summary: AbstractBinAsyncEntityProducer.produceData called again
after StreamChannel.endStream
Key: HTTPCORE-635
URL: https://issues.apache.org/jira/browse/HTTPCORE-635
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 5.0.1
Reporter: Pedro Lamarão
Attachments: InputStreamServerHandler.java
We extend AbstractBinAsyncEntityProducer to stream from an InputStream. While
investigating a conceptually higher-level problem, we have hit the following
situation. In the attached code file, our program raises the assertion at line
66.
The documentation for produceData asserts "the ability of the underlying byte
channel to accept more data" and the documentation for endStream asserts
"terminates the underlying data stream". Though not explicitly stated, it seems
obvious that, after endStream, the underlying stream cannot accept more data.
Our original problem is a test case where the server program apparently does
not actually send the response entity to the client program. Client logs
indicate there is no response body, and debugging revealed that produce
eventually calls endStream twice in a row.
