As discussed over IRC the common code HttpConnection shouldn't contain a subsystem-specific code, which in this case is setting the content type to application/x-www-form-urlencoded for TPS. 2. Also discussed over IRC, there's an existing issue with HttpConnection constructors: <a class="moz-txt-link-freetext" href="https://fedorahosted.org/pki/ticket/891">https://fedorahosted.org/pki/ticket/891</a> Suppose that issue is fixed later, it should be possible to merge the constructors. Then instead of calling different constructors for different timeout values like this: if (timeout == 0) { connector = new HttpConnector( null, nickname, remauthority, resendInterval, conf); } else { connector = new HttpConnector( null, nickname, remauthority, resendInterval, conf, timeout); } it can be simplified like this: connector = new HttpConnector( null, nickname, remauthority, resendInterval, conf, timeout); There's also a similar code in HttpConnFactory. 4. In HttpConnection the existing constructors were changed to pass "" as the default value of op. I think we should just pass a null value. This way the code can simply check the op like this: this(dest, factory, null); ... if (op == null) If we really want to accept an empty string, then probably we should normalize the string by trimming the white spaces before checking for empty string. 5. The HttpConnection.send() checks if the parameter is null or empty string then returns a null value with a comment "throw later". This error will only be detected later if another code tries to use the null return value, but at that point we're looking at a secondary issue, which makes it harder to troubleshoot. I think in general it's better to throw an exception as soon as the error is detected. 6. The HttpConnection.send() checks for untrusted certificate by checking the exception message. This may work now but could become inaccurate later due to translation, text changes, or typo. It would be better if there's a specific exception type or error code that we can check for this specific case. 7. Similar to #5, HttpConnection.send() swallows NumberFormatException. I think we should not catch this to detect the error as early as possible and also NumberFormatException is already a RuntimeException so it doesn't need to be wrapped/declared. 8. Similar to #5, the HttpConnector.send() (not HttpConnection) would swallow the exception so some errors wouldn't be detected immediately. I think the code could be simplified as follows (the send() already throws EBaseException): try { curConn = mConnFactory.getConn(op); return curConn.send(msg); } finally { if (curConn != null) { mConnFactory.returnConn(curConn); } } 9. Similar to #5, the ConnectionManager.getXMLparser() would swallow the exceptions. I think it would be better to wrap the exception in a RuntimeException and rethrow it. try { ByteArrayInputStream bis = new ByteArrayInputStream(text.getBytes()); return new XMLObject(bis); } catch (Exception e) { CMS.debug("TPSSubsystem: getXMLparser(): failed: "+ e.toString()); throw new RuntimeException(e); } We can change this code again in the future if necessary to use a more specific class or add the original exceptions into the throws list. 10. In ConnectionManager, the createConnector() will never return a null, so it's not necessary to check its return value in initConnectors(). It will simplify the code and some code analyzers like Coverity probably will report the part that handles the null case as dead code anyway. 11. Just some minor things: - The debug log in getXMLparser() should say "ConnectionManager" instead of "TPSSubsystem". - If we use camel-case consistently, the name should be getXMLParser() (with upper-case P). - Some toString() invocations are redundant because string concatenation will call it automatically. I'll leave it to others to review the functionality correctness. </blockquote> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ Pki-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:Pki-devel@redhat.com">Pki-devel@redhat.com</a> <a class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/pki-devel">https://www.redhat.com/mailman/listinfo/pki-devel</a></pre> </blockquote> </body> </html>
