I want to load achievement screen in my gamecenter. The GKAchievement completeHandler is returing blank array of achievement and so Error is coming
"Error Domain=GKErrorDomain Code=3 "The requested operation could not be completed due to an error communicating with the server." UserInfo=0xae232f0 {NSUnderlyingError=0xae2f9b0 "The operation couldn’t be completed. status = 5044, Game does not support achievements", NSLocalizedDescription=The requested operation could not be completed due to an error communicating with the server.}
And achievement screen is showing "unable to load achievement". What is cause of this error?
I had this exact same issue even after enabling the application in iTunesConnect. My problem was that I was authenticating the user in the AppDidFinishLaunching callback. Try moving this call forward to after the app launches and it should clear it up if you are having the same issue that I did.

I use pythonsdk and naoqi for programming my pepper robot. i created a session and call the main by it is follows:
try
session = qi.Session()
session.connect("tcp://#.#.#.#:9559")
except RuntimeError:
print ("Cannot connect to robot ")
main(session)
each run of my program may take about 2 hourse. Actually it is a toutrial based interaction which is a loop of two phase: robot speech and playing a video clip on pepper's tablet, then a new topic and new video clip and so on.
but after a while i got these errors:
RuntimeError: Session not connected.
RuntimeError: Socket is not connected
so what these errors mean? and how can i overcome them? Thanks in advance
You should make sure your session remains alive, by using it from the scope it was created:
session = qi.Session()
session.connect("tcp://#.#.#.#:9559")
main(session)
I'm trying to stream MutationGroups into spanner with SpannerIO.
The goal is to write new MuationGroups every 10 seconds, as we will use spanner to query near-time KPI's.
When I don't use any windows, I get the following error:
Exception in thread "main" java.lang.IllegalStateException: GroupByKey cannot be applied to non-bounded PCollection in the GlobalWindow without a trigger. Use a Window.into or Window.triggering transform prior to GroupByKey.

Because of the error above I assume the input collection needs to be windowed and triggered, as SpannerIO uses a GroupByKey (this is also what I need for my use case):
...
.apply("1-minute windows", Window.<MutationGroup>into(FixedWindows.of(Duration.standardMinutes(1)))
.triggering(Repeatedly.forever(AfterProcessingTime
.pastFirstElementInPane()
.plusDelayOf(Duration.standardSeconds(10))
).orFinally(AfterWatermark.pastEndOfWindow()))
.discardingFiredPanes()
.withAllowedLateness(Duration.ZERO))
.apply(SpannerIO.write()
.withProjectId(entityConfig.getSpannerProject())
.withInstanceId(entityConfig.getSpannerInstance())
.withDatabaseId(entityConfig.getSpannerDb())
.grouped());
When I do this, I get the following exceptions during runtime:
java.lang.IllegalArgumentException: Attempted to get side input window for GlobalWindow from non-global WindowFn

After investigating further it appears to be due to the .apply(Wait.on(input)) in SpannerIO: It has a global side input which does not seem to work with my fixed windows, as the docs of Wait.java state:
If signal is globally windowed, main input must also be. This typically would be useful
* only in a batch pipeline, because the global window of an infinite PCollection never
* closes, so the wait signal will never be ready.
As a temporary workaround I tried the following:
add a GlobalWindow with triggers instead of fixed windows:
.apply("globalwindow", Window.<MutationGroup>into(new GlobalWindows())
.triggering(Repeatedly.forever(AfterProcessingTime
.pastFirstElementInPane()
.plusDelayOf(Duration.standardSeconds(10))
).orFinally(AfterWatermark.pastEndOfWindow()))
.discardingFiredPanes()
.withAllowedLateness(Duration.ZERO))
This results in writes to spanner only when I drain my pipeline. I have the impression the Wait.on() signal is only triggered when the Global windows closes, and doesn't work with triggers.
Disable the .apply(Wait.on(input)) in SpannerIO:
This results in the pipeline getting stuck on the view creation which
is described in this SO post:
SpannerIO Dataflow 2.3.0 stuck in CreateDataflowView.
When I check the worker logs for clues, I do get the following warnings:
logger: "org.apache.beam.sdk.coders.SerializableCoder"
message: "Can't verify serialized elements of type SpannerSchema have well defined equals method. This may produce incorrect results on some PipelineRunner
logger: "org.apache.beam.sdk.coders.SerializableCoder"
message: "Can't verify serialized elements of type BoundedSource have well defined equals method. This may produce incorrect results on some PipelineRunner"
Note that everything works with the DirectRunner and that I'm trying to use the DataflowRunner.
Does anyone have any other suggestions for things I can try to get this running? I can hardly imagine that I'm the only one trying to stream MutationGroups into spanner.
Thanks in advance!
Currently, SpannerIO connector is not supported with Beam Streaming. Please follow this Pull Request which adds streaming support for spanner IO connector.
I am using avahi for service advertisement and discovery.
As we all know avahi needs dbus as well and hence dbus-1.6.8 library is also added.
i am starting dbus-daemon and avahi-daemon at startup. both daemons are running, which i could see in process list.
But when I try to create avahi client, ::avahi_client_new call fails with error "An unexpected D-Bus error occured", which is AVAHI_ERR_DBUS_ERROR = -22, /**< An unexpected D-Bus error occured */
Bellow is my function all.
Client = ::avahi_client_new(
::avahi_threaded_poll_get(Poll),
static_cast<AvahiClientFlags>(0),
&AvahiWrapper::OnClientStateChange,
NULL,
&error);
PS: Poll = ::avahi_threaded_poll_new(); is successful.
Please let me if anyone has any clue on this problem. Or at-least how to debug.
Thanks in advance.
I am checking my SQL connection state as:
_ConnectionPtr m_pADOConnection;
// Connection is created and working fine...
// Now I disable network adapter (from Control panel)
if( (pApp->m_pConnection->GetState() == adStateOpen) )
{
// I got here every time....
}
The problem is I get every time adStateOpen even if connection is really not working!
If I try to execute a query or do anything it fails, mostly with
SMux Provider: Physical connection is not usable [xFFFFFFFF].
or
Error number: 80004005 = Unable to open a logical session
Is this value of State property reliable or I need to perform some other check top detect this state?
The state property does not become 0 (adStateClosed) when the connection is interrupted. So checking the state of the connection will always return 1 (adStateOpen) even after the connection is interrupted.
No there is no way to check immediately. The architecture of SQL servers don't allow for it.
I advise you to create an error handling.
It looks as though the only way to establish that the connection has been lost is to try to open it and handle the error.
We are building a RTB(real time bidding) platform. Using nginx as http server, the bidder is writen in lua, google protocol buffer for serializing data and Zlog for logs. After test runs, we got three error messages in the nginx error log:
"[libprotobuf Error, google/protobuf/wire_format.cc:1053]
String field contains invalid UTF-8 data when parsing a protocol buffer.
Use the 'bytes' type if you intend to send raw bytes."
So we went back to check the source code of protocol buffer, and found that this check is controlled by a macro(-DNDEBUG: it means NOT debug mode?, according to the comment). And -DNDEBUG disables GOOGLE_PROTOBUF_UTF8_VALIDATION(i think?). So, we enabled this macro(-DNDEBUG) in the configuration. However, after testing, we still got the same error message. And then, we changed all the "String" type to "Bytes" typr in XXX.proto. After testing, the same error message showed.
worker process 53574 exited on signal 11(core dumped),then process died.
lua entry thread aborted: runtime error:/home/bilin/rtb/src/lua/shared/log.lua:34: 'short' is not callable"
Hope somebody can help us solving those problems.
Thank you.
