[ http://issues.apache.org/jira/browse/HTTPCLIENT-385?page=all ]
Oleg Kalnichevski updated HTTPCLIENT-385:
-----------------------------------------
Component: HttpConn
(was: HttpClient)
> Access to SO_TIMEOUT for open connections
> -----------------------------------------
>
> Key: HTTPCLIENT-385
> URL: http://issues.apache.org/jira/browse/HTTPCLIENT-385
> Project: HttpComponents HttpClient
> Type: Improvement
> Components: HttpConn
> Versions: 3.0 Alpha 2
> Environment: Operating System: All
> Platform: All
> Reporter: Gustavo Hexsel
> Assignee: HttpClient Dev
> Priority: Minor
> Fix For: 4.0 Alpha 1
>
> I'm trying to access a set of pages in order, for which I have a maximum delay
> permissible. The complete operation includes following all redirects and
> fetching the complete page content. What I need, which doesn't seem to be
> doable right now (according to the common-users list) is to reset the
> SO_TIMEOUT
> property of the socket before each read to the inputstream. I'd need an
> access
> to the HttpConnection, or a way to set the parameters for that object.
> This is a simplified version of what I'm doing:
> -----
> HttpURL url = new HttpURL(urlString);
> method.setURI(url);
> method.setFollowRedirects(false);
> method.getParams().setSoTimeout(remainingTime);
> HostConfiguration hostConfig = new HostConfiguration();
> hostConfig.setHost(url);
> method.setHostConfiguration(hostConfig);
> timeoutChecker.getRemainingTime());
> int statusCode = client.executeMethod(hostConfig, method, state);
> String pageContent;
> if (isRedirect(statusCode)) {
> if (timeoutChecker.isTimeout()) {
> throw new TimeoutException("Total execution time for fetch exceeded
> timeout parameter");
> } else {
> Header locationHeader = method.getResponseHeader("location");
> HttpURL nextLocation = new
> HttpURL(locationHeader.getValue().toCharArray());
> pageContent = fetchGet(nextLocation.getEscapedURI(), addressHolder,
> timeoutChecker, state);
> }
> } else if (isSuccess(statusCode)) {
> // at least 4K buffers, might be as big as the webpage
> int responseSize = Math.max(getResponseSize(method),
> DEFAULT_RESPONSE_SIZE);
> InputStream response = method.getResponseBodyAsStream();
> ByteArrayOutputStream outstream = new ByteArrayOutputStream(responseSize);
> byte[] buffer = new byte[responseSize];
> int len;
> do {
> // ***TODO need to reset the SO_TIMEOUT to the remaining time
> len = response.read(buffer);
> outstream.write(buffer, 0, len);
> while ((len > 0) && !timeoutChecker.isTimeout());
> outstream.close();
> pageContent = EncodingUtil.getString(outstream.toByteArray(),
> method.getResponseCharSet());
> response.close();
> } else {
> ...
> }
