I want to set the star-mail messages to the inbox, now I just can and cancel starred in the first success in the future, will not have any effect.
The following is the way I useļ¼
add start
[imapSession storeFlagsOperationWithFolder:"INBOX"
uids:[MCOIndexSet indexSetWithIndex:11]
kind:MCOIMAPStoreFlagsRequestKindAdd
flags:MCOMessageFlagFlagged];
add remove
[imapSession storeFlagsOperationWithFolder:"INBOX"
uids:[MCOIndexSet indexSetWithIndex:11]
MCOIMAPStoreFlagsRequestKindRemove

I am simulating the passenger changeover process in metros using the Anylogic Pedestrian Library.
When passengers enter the vehicle, a seat is assigned to them from the seats available near the door (within a given distance) they entered the vehicle through, using a function called lookForSeat. If there is no more free seat available, their boolean parameter wantToSit is set to false and they will stay standing.
The parameter wantToSit is predefined for the Passenger Agent, with default value randomtrue(0.8). But even if I set it to default value = 1, I get the same error.
Then, passengers are separated using a PedSelectOutput block:
Condition 1: if ped.WantToSit = true --> they are sent to their
assigned seat coordinates (PointNode 'seatPoint', null by default)
Condition 2: true (thus, ped.WantToSit = false) --> they stay in the
standing area in the vehicle, no assigned seatPoint necessary in this case.
Now, it works pretty well, but when the majority of the seats is already occupied, suddenly the PedSelectOutput block directs a passenger with ped.wantToSit to its seating point, which gives null and I get the NullPointerException error.
Attached you find the function, the settings of PedSelectOutput and the log from the command.
As it can be seen, the PedSelectOutput sends the passenger through exit 1 (which gives the error due to calling the coordinates of a "null"), despite ped.wantToSit = false.
Any ideas, what is going wrong? For me it really looks like the function is working properly - I have been changing it the whole day until I realized that something in the PedSelectOutput block goes wrong.
Thank you in advance!

The problem here is a subtle one, which has caused me many hours of debugging as well. What you need to understand is that the on exit code is only executed once the agent already has a path to which it is going to exit. i.e. the selectOutput and subsequent blocks are already evaluated and only once it is determined that the agent can move to the next block then the on exit code is called. But the agent will continue on its chosen path that has been determined before the on exit code has been executed.
See the small example below:
I have a pedestrian with a variable that is true by default and a select output that checks this value
If I ran the model all pedestrians exit at the top option, as expected
If I change the variable to false on the On Exit code I might expect that all pedestrians will now exit at the second option
But they don't there is no change....
If I add the code to the on enter code then it does..
I am setting up my Splunk search/alert to search for an error in a group of servers. How can i set the alert to mail me when the error happens on multiple hosts but only once for each host?
For example, if the error is continuously happening on two hosts from a group of 6, I need to get two alerts(one for each host) but only once till the next day. (for the once till the next day option I am using the throttling feature)
Is that possible with splunk?
I figured it out. In the throttle settings, I put the suppress the field value as host and set the alert for every occurence. This way, it sent alert once for all the hosts and then supressed everything till the supress threshold.
To throttle by specific fields you must select the "For each result" option in the Trigger Conditions section. Then put "host" in the "Suppress results containing field value" box.
See http://docs.splunk.com/Documentation/Splunk/7.2.0/Alert/ThrottleAlerts
I've found a possible answer to this question in a Google Group but I'll like to know if it's correct and add a follow-up question if it is correct.
The answer there is
Every time the global update function in your app runs for any reason,
the global subscriptions object is reevaluated as well, and effect
managers receive the new list of current subscriptions
If any time the model is changed subscriptions get called what is the effect on subscriptions such as Time.every second taken from Time Effect Elm Guide - is that means the timer get reset when the model changes? What if that was Time.every minute - if the model changes 20 seconds after it starts will it fire in 60 - 20 = 40 seconds or will it fire in 1 minute?
You can check when update and subscriptions are called by adding a Debug.log statement to each. The subscriptions function is called first at the start (since the messages which will be sent to update may depend on it) and also after each call to update.
The timer interval seems to be unaffected by subsequent calls to subscriptions. For example, if you use the elm clock example, change the subscription to
Time.every (10*Time.second) Tick
and add a button to the view which resets the model value to 0, you will see that the tick still takes place at regular 10s intervals, no matter when you click the button.
TLDR; It will fire in 1 minute, unless you turn your subscription
off and on during the first minute
Every time your update runs, the subscriptions function will run too.
The subscriptions function essentially is a list of things you want your app to subscribe to.
In the example you have a subscription that generates a Tick message every 60 seconds.
The behavior you may expect is:
T= 0s: The first time subscriptions runs, you start your subscription to "receive Tick message every 60 seconds".
T= between 0 AND 60s: As long as that particular subscription remains ON, it doesn't matter how often your update function runs. subscriptions will be run, but as long as your particular subscription to the Tick remains ON, things are fine.
T= 60s: You receive a Tick message from your subscription, which in turn will fire update to be called.
T= 60s: subscriptions will run again (because of previous call to update)
What could be interesting is what happens if the subscription to Tick is canceled along the way and then reinstated:
T= 0: subscription to Tick
T= 20s: suppose something changes in the model, causing subscription to Tick to be canceled
T= 40s: some other change in model, causing subscription to Tick to be turned on again
T= 100s: Tick message is fired, and passed to update function
T= 100s: subscriptions will run again
I have a telegram bot that for any received message runs a program in the server and sends its result back. But there is a problem! If a user sends too many messages to my bot(spamming), it will make server so busy!
Is there any way to block the people whom send more than 5 messages in a second and don't receive their messages anymore? (using telegram api!!)
Firstly I have to say that Telegram Bot API does not have such a capability itself, Therefore you will need to implement it on your own and all you need to do is:
Count the number of the messages that a user sends within a second which won't be so easy without having a database. But if you have a database with a table called Black_List and save all the messages with their sent-time in another table, you'll be able to count the number of messages sent via one specific ChatID in a pre-defined time period(In your case; 1 second) and check if the count is bigger than 5 or not, if the answer was YES you can insert that ChatID to the Black_List table.
Every time the bot receives a message it must run a database query to see that the sender's chatID exists in the Black_List table or not. If it exists it should continue its own job and ignore the message(Or even it can send an alert to the user saying: "You're blocked." which I think can be time consuming).
Note that as I know the current telegram bot API doesn't have the feature to stop receiving messages but as I mentioned above you can ignore the messages from spammers.
In order to save time, You should avoid making a database connection
every time the bot receives an update(message), instead you can load
the ChatIDs that exist in the Black_List to a DataSet and update the
DataSet right after the insertion of a new spammer ChatID to the
Black_List table. This way the number of the queries will reduce
noticeably.
I have achieved it by this mean:
# Using the ttlcache to set a time-limited dict. you can adjust the ttl.
ttl_cache = cachetools.TTLCache(maxsize=128, ttl=60)
def check_user_msg_frequency(message):
print(ttl_cache)
msg_cnt = ttl_cache[message.from_user.id]
if msg_cnt > 3:
now = datetime.now()
until = now + timedelta(seconds=60*10)
bot.restrict_chat_member(message.chat.id, message.from_user.id, until_date=until)
def set_user_msg_frequency(message):
if not ttl_cache.get(message.from_user.id):
ttl_cache[message.from_user.id] = 1
else:
ttl_cache[message.from_user.id] += 1
With these to functions above, you can record how many messages sent by any user in the period. If a user's messages sent more than expected, he would be restricted.
Then, every handler you called should call these two functions:
#bot.message_handler(commands=['start', 'help'])
def handle_start_help(message):
set_user_msg_frequency(message)
check_user_msg_frequency(message)
I'm using pyTelegramBotAPI this module to handle.
I know I'm late to the party, but here is another simple solution that doesn't use a Db:
Create a ConversationState class to attach to each telegram Id when they start to chat with the bot
Then add a LastMessage DateTime variable to the ConversationState class
Now every time you receive a message check if enought time has passed from the LasteMessage DateTime, if not enought time has passed answer with a warning message.
You can also implement a timer that deletes the conversation state class if you are worried about performance.
I am facing the following problem:
I have multiple HTTP Requests in my testplan.
I want every request to be repeated 4 times if they fail.
I realized that with a BeanShell Assertion, and its already working fine.
My problem is, that I don't want requests to be executed if a previous Request failed 5 times,
BUT I also dont want the thread to end.
I just want the current thread iteration to end,
so that the next iteration of the thread can start again with the 1st request (if the thread is meant to be repeated).
How do I realize that within the BeanShell Assertion?
Here is just a short extract of my code where i want the solution to have
badResponseCounter is being increased for every failed try of the request, this seems to work so far. Afterwards, the variable gets resetted.
if (badResponseCounter = 5) {
badResponseCounter = 0;
// Stop current iteration
}
I already checked the API, methods like setStopTest() or setStopThread() are given, but nothing for quitting the current iteration. I also need the preference "continue" in the thread group, as otherwise the entire test will stop after 1 single request failed.
Any ideas of how to do this?
In my opinion the easiest way is using following combination:
If Controller to check ${JMeterThread.last_sample_ok} and badResponseCounter variables
Test Action Sampler as a child of If Controller configured to "Go to next loop iteration"
Try this.
ctx.setRestartNextLoop(true);
if the thread number is 2, i tried to skip. I get the below result as i expected (it does not call b-2). It does not kill the thread either.
