Subject [jira] Commented: (HTTPCLIENT-829) ChunkedInputStream does not handle sockets with timeouts
Date Wed, 25 Feb 2009 09:51:01 GMT

Oleg Kalnichevski commented on HTTPCLIENT-829:
----------------------------------------------

Adam,

Socket timeouts are signalled as SocketTimeoutException. In case of a socket timeout there
will be no more attempts to read from the input stream. Probably you mean end of stream condition,
not a timeout? 

There is basically no point fixing HttpClient 3.x, as it is nearing its end of life. 

By looking at the code I do not think HttpClient 4.0 is affected. I believe the end of stream
conditions are handled correctly. If you are able to reproduce the problem with HttpClient
4.0, feel free to submit a patch or a test case. Otherwise I'll close this issue as won't
fix.

Oleg

> ChunkedInputStream does not handle socket timeouts when reading data. If a socket timeout
is received after finishing reading a chunk (including it's CRLF combination) and before reading
the next chunk's length, the next call to read will attempt to re-read the CRLF, causing an
IOException with the message "CRLF expected at end of chunk" to be thrown. I have only tested
this with 3.0 but it doesn't appear to be fixed in 3.1 or any 4.0 from looking at the code.
