Bug #: 52055
Summary: ChunkedInputFilter is not recycled for servlet 3.0
asynchronous request
Product: Tomcat 7
Version: 7.0.22
Platform: Macintosh
Status: NEW
Severity: critical
Priority: P2
Component: Servlet & JSP API
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
I'm using the standard servlet 3.0 async APIs with tomcat 7.0.22. The server
side code is something like the following:
final AsyncContext asyncContext = request.startAsync();
... // in a processing thread
asyncContext.getRequest().getInputStream();
... read the input stream
asyncContext.complete();
The InputStream returns 0 bytes for the HTTP post with chunking.
After debugging, I found that the ChunkedInputFilter is reused by
org.apache.coyote.http11.AbstractInputBuffer. But it has never been recycled
(nextRequest()?) before the reuse for another request. As a result, the
endChunk flag is always true after the first request. And it always return
immediately without reading more from the buffer.
