when i try to synchronize my caldav server implementation with Thunderbird 45.4.0 and Lightning 4.7.4 (one particular calendar collection) it doesnt show any data or events in the calendar though the last call of the sequence provided the data.
In the Thunderbird error log i can see one error:
Zeitstempel: 07.11.16, 14:21:12
Fehler: [calCachedCalendar] replay action failed: null,

Zeile: 327
the call sequence is as follows (detailed content via gist-links):
Propfind Request - Response
Options Request - Response
Propfind Request - Response
Report Request - Response - Response Raw
The synchronization with other clients like macOS-calendar and ios-calendar works in principle and shows the data. Does anyone has a clue what is going wrong here?
Not sure whether that is the cause but I can see two incorrect things:
a) Your <href/> property has trailing spaces:
<d:href>/sap/sports/webdav/appsvc/webdav/services/server.xsjs/cal/_D043133/EVENT%3A070768ba5dd78ff15458f1985cdaabb1.ics
</d:href>
b) your ORGANIZER property is not a valid URI
ORGANIZER:_D043133
i was able to find the cause of the above issue by debugging Thunderbird as propsed by Philipp. The Report Response has http status code 200, but as it is a multistatus response Thunderbird/Lightning expects status code 207 ;-)
Thanks for the hints!

Basically, I am facing an issue while n number of taskqueues are running in the Google Cloud Platform. There is no error in code or server but the execution of the taskqueues got terminated due to instance unavailability by which it will trigger a taskqueue again and again.
I know a few reasons by which this kind of termination process takes place.
Reasons:
Instance Unavailable
App Error / AppEngine Error
Memory Exceeded
I want to know the other possible values for the X-AppEngine-TaskRetryReason header.
For example (the response of GAE):
self.request.headers {'Content_Length': '432', 'Content-Length': '432', 'X-Appengine-Current-Namespace': '75f4910a-b925-4945-92f0-b214a459f0be', 'X-Appengine-Taskexecutioncount': '1', 'X-Appengine-Tasketa': '1624452214.545367', 'User-Agent': 'AppEngine-Google; (+http://code.google.com/appengine)', 'X-Appengine-Taskpreviousresponse': '503', 'Host': 'payqa-dot-hw-pay.qa.appspot.com', 'X-Appengine-Taskretrycount': '2', 'Referer': 'http://payqa-dot-hw-pay.qa-.appspot.com/pay/runpayroll', 'Content_Type': 'application/octet-stream', 'X-Cloud-Trace-Context': 'd44fdfd56bc7733afb3169fb354b80ed/6659926505008598367', 'Traceparent': '00-d44fdfd56bc7733afb3169fb354b80ed-5c6ccfded93f0d5f-00', 'X-Appengine-Queuename': 'payroll', 'X-Appengine-Taskname': '21925984910338157231', 'Content-Type': 'application/octet-stream', 'X-Appengine-Country': 'ZZ', **'X-Appengine-Taskretryreason': 'Instance Unavailable'**}
Like I mentioned in the comments there is no listing in the documentation for the possible values of X-AppEngine-TaskRetryReason and it only states that it represents:
The reason for retrying the task.
That being said there is two possibilities why this happens, either this has no specific value and just spits out whatever message it is passed to it by the actual class or component that generated the failure of the execution of the tasks or this is not being shared because the Google Cloud team did not considered it necessary.
Either way if you want to know why this happens and what values you can expect, you should open a Customer issue in Google's Issue Tracker so you can check why this is not shared in the documentation with their Engineering team.
I have a Camel rest endpoint (Jetty) which validates and processes incoming requests. Besides specific Exception handlers (onException) it uses a DLQ error handler (errorHandler(deadLetterChannel...)) which is setup to retry 3 times - if unsuccessful the message is moved to the DLQ.
My question is, how do I still return a user friendly error message back to the client if an unexpected Exception occurs rather than the full Exception body? Is there some config I'm missing on the errorHandler?
I've tried to find some examples on the camel unit tests (DeadLetterChannelHandledExampleTest) and camel in action 2 (Chapter 11) but none seemed to have specific examples for this scenario.
Code is:
.from(ROUTE_URI)
.errorHandler(deadLetterChannel("{{activemq.webhook.dlq.queue}}")
.onPrepareFailure(new FailureProcessor())
.maximumRedeliveries(3)
.redeliveryDelay(1000))
.bean(ParcelProcessor.class, "process");
Thank you for your help!
Use a 2nd route as the DLQ, eg direct:dead and then send the message first to the real DLQ, and then do the message transformation afterwards to return a friendly response.
errorHandler(deadLetterChannel("direct:dead")
from("direct:dead")
.to("{{activemq.webhook.dlq.queue}}")
.transform(constant("Sorry something was wrong"));
I am trying to develop a server application using mongoose C library. In the initial stage of the my try, I am stuck at sending a response for an HTTP request. I am trying to send a simple response of status 200 using following line of code:
mg_send_response_line(nc, 200, "Access-Control-Allow-Origin: *");
printf("Response sent...\n");
But the response is not received to the client(Postman or web-browser).
There is no error, and even the printf line of Response sent is printed.
As against to this, following lines are getting executed successfully:
mg_http_send_error(nc,404, "Fatal Error!"); // I get this error at client side.
The basic simplest_web_server also works fine. Why is my single line of code sending response failing. I am not able to understand/ debug this.
Regards,
Neeraj.
The issue is that there is no content length or transfer encoding specified for the HTTP response and the server does not close the connection so the client hangs waiting for the response.
If you look through the source code, you will see that in mg_http_send_error(), the MG_F_SEND_AND_CLOSE flag is set but it is not set within mg_send_response_line() (though, like you, I assumed that this would be handled by the function).
To fix the issue in your context,
mg_send_response_line(nc, 200, "Access-Control-Allow-Origin: *");
printf("Response sent...\n");
nc->flag |= MG_F_SEND_AND_CLOSE;
I have a requirement which is as follows:
Accept HTTP POST requests containing XML to a certain URL.
Perform pre-requisite actions such as saving the request XML to a file.
Validate the incoming XML matches the corresponding schema.
If the schema validation fails, synchronously respond with a HTTP 400 response code.
If the schema validation passes, synchronously respond with a HTTP 200 response code.
Pass the XML message on for further processing.
When this further processing completes, asynchronously respond to the caller with a HTTP 200 response code.
This is currently how I have the route configured:
onException(IOException.class)
.log(LoggingLevel.INFO, "Schema validation error on incoming message: ${id}")
.handled(true)
.maximumRedeliveries(0)
.process(schemaValidationErrorProcessor);
from("restlet:http://localhost:" + portNum + "/api/XX/XXX?restletMethod=POST")
.log(LoggingLevel.INFO, "Received message")
.convertBodyTo(String.class)
.multicast()
.parallelProcessing()
.to(SAVE_REQUEST_TO_FILE_QUEUE, PROCESS_PROVISIONING_REQUEST_QUEUE);
from(SAVE_REQUEST_TO_FILE_QUEUE)
.log(LoggingLevel.INFO, "Storing message: ${id}")
.to("file://" + requestLogFolder);
from(PROCESS_PROVISIONING_REQUEST_QUEUE)
.log(LoggingLevel.INFO, "Processing provisioning request: ${id}")
.process(requestGate)
.choice()
.when(header(SYSTEM_STATUS_HEADER).isEqualTo(true))
.unmarshal(xmlParser)
.inOnly("bean:requestHandler?method=handle")
.when(header(SYSTEM_STATUS_HEADER).isEqualTo(false))
.log(LoggingLevel.INFO, "Intentially dropping message")
.endChoice();
The schema validation part is achieved via the .unmarshal(xmlParser) line (I have a JaxbDataFormat object configured elsewhere with the schema set in that). When schema validation fails, an IOException is thrown and this is handled by my schemaValidationErrorProcessor which adds the HTTP 400 to the response.
That is all working fine.
The problem I am having is passing the XML message on for further processing. Basically, I need this to be done asynchronously because when the schema validation passes I need to synchronously respond with a 200 response. The processing that I need to do is in the .inOnly("bean:requestHandler?method=handle") line.
I naively thought that setting the routing to my bean to inOnly would set this to be asynchronous and that main route would not wait for a response. However, this is not the case as when the requestHandler.handle method throws an exception, this is thrown back to the caller of the REST endpoint. I don't want this to happen as I want all of this processing to be done in 'the background' as the consumer will have already received a 200 response.
So, my question is, how would I go about achieving such behaviour? I have thought about using queues etc but ideally would like to avoid such components if possible.
Use Camel Websocket component for asynchronously respond to the caller.
From the Camel documentation:
from("activemq:topic:newsTopic")
.routeId("fromJMStoWebSocket")
.to("websocket://localhost:8443/newsTopic?sendToAll=true&staticResources=classpath:webapp");
I am Indexing Documents by using SolrPhpClient library. while making POST request by Solr using extract function reply with
URL http://localhost/moodledemo/pluginfile.php/99/course/overviewfiles/pre bio- data.docx returned non 200 response code".
It happens only if the file name include space. if the filename don't have any space it goes well.
I don't conclude why it returns non 200 response with files that have space in their names. while accessing the same path works in browser.
Using rawurlencode() Solved the Issue..
may be the jetty server was responding with non 200 response code with the filename:-
