I am trying to execute the following script and getting the below error. Redis is running in docker
Exception in thread "main" org.redisson.client.RedisException: ERR

'print' script: 6f736423f082e141036b833d1f86b5a36a494611, on

I get the same error when I execute using redis CLI

checked the Lua print on the same line thread but io.write also is giving same error.
As in the comments wrote return() seems* the only way.
Example for redis-cli (set redis DB and use it in Lua)
(Collect Data and return as one string)
set LuaV 'local txt = "" for k, v in pairs(redis) do txt = txt .. tostring(k) .. " => " .. tostring(v) .. " | " end return(txt)'
Now the eval
eval "local f = redis.call('GET', KEYS[1]) return(loadstring(f))()" 1 LuaV
...shows whats in table: redis
(One long String no \n possible)
Exception: eval 'redis.log(2, _VERSION)' 0 gives out without ending the script but only on the server.
Than \n will work when you do...
set LuaV 'local txt = "" for k, v in pairs(redis) do txt = txt .. tostring(k) .. " => " .. tostring(v) .. "\n" end return(txt)'
...and the eval
eval 'local f = redis.call("GET", KEYS[1]) f = loadstring(f)() redis.log(2, f)' 1 LuaV
I'm upgrading my Ionic 3 app to Ionic 4.
I'm working google maps and markers. I added few buttons in infoWindow and declared an attirbute data-id. Now I want to get these buttons using this attribute data-id
Here's the related code:
let content = '<b>' + locations[i].name + '</b><br/>' + locations[i].street + "<br/>";
content += "<button id='edit-customer-" + i + "' class='edit-customer button button-md button-default-secondary button-default-md' ion-button data-id='" + locations[i].id + "'>Editar</button>";
content += "<button id='order-customer-" + i + "' class='order-customer button button-md button-default-secondary button-default-md' ion-button data-id='" + locations[i].id + "'>Pedido</button>";
content += "<button id='event-customer-" + i + "' class='event-customer button button-md button-default-secondary button-default-md' ion-button data-id='" + locations[i].id + "'>Evento</button>";
infowindow.setContent(content);
google.maps.event.addListenerOnce(infowindow, 'domready', () => {
let infoWindow = infowindow;
document.getElementById('edit-customer-' + i).addEventListener('click', (event) => {
var targetElement = (<HTMLButtonElement>event.target || event.srcElement);
var id = targetElement.getAttribute("data-id"); //getAttribute shows syntax error 'Property "getAttribute" does not exist on type "EventTarget"'
infoWindow.close();
me.editCustomer(id);
});
});
var id = targetElement.getAttribute("data-id");
syntax error 'Property getAttribute does not exist on type EventTarget'
Am I doing something wrong?
Any alternate way to getAttribute?
This code is giving me error in jenkins
groovy.lang.MissingPropertyException: No such property: Metrics for class: java.lang.String
def init_metrics(){
env.previousStageEnd = 0
env.stageDuration
env.stageTimes = [:]
}
init_metrics()
node{
stage('Metrics'){
println " - " + env.previousStageEnd + " - " + env.stageTimes + " - " + env.stageDuration + " - " + env.STAGE_NAME
env.stageTimes[env.STAGE_NAME] = currentBuild.duration - (env.previousStageEnd as int)
previousStageEnd = currentBuild.duration
}
}
the problem with this guy here env.stageTimes[env.STAGE_NAME] for some reasons I can't add environment stage_name in another environment declared by me. it works only if those variables are not environment but local.
solution to this would be to define environment = []
def init_metrics(){
environment = [
previousStageEnd = 0,
stageDuration = null,
stageTimes = [:]
]
}
init_metrics()
node{
stage('Metrics'){
println " - " + env.previousStageEnd + " - " + env.stageTimes + " - " + env.stageDuration + " - " + env.STAGE_NAME
env.stageTimes[env.STAGE_NAME] = currentBuild.duration - (env.previousStageEnd as int)
previousStageEnd = currentBuild.duration
}
}
I have this code in a lua script which I run from .net.
const string script = " if redis.call('EXISTS', '{0}') == 1 then" +
" local user = redis.call('get','{0}')" +
" local value = cjson.decode(user)" +
" value['UserPreferences'] = cjson.decode('{1}')" +
" value['Timestamp'] = cjson.decode('{2}')" +
" local val=cjson.encode(value)" +
" redis.call('set', '{0}', val)" +
" redis.call('EXPIRE', '{0}','{3}')" +
" end";
var redisScript = string.Format(script, "User_" + userId, JsonConvert.SerializeObject(userPreferences), JsonConvert.SerializeObject(DateTime.UtcNow), ConfigurationManager.AppSettings["RedisKeyExpiryTime"]);
await Cache.ScriptEvaluateAsync(redisScript);
This returns the error :
Error: ERR value is not an integer or out of range
please give some feedback to solve the issue.
Is there any support for html5 browser 'desktop notifications' in Vaadin? I've looked for this and can't find anything specific.
I've tried something like this with no luck.
JavaScript.getCurrent().execute(
"if (window.webkitNotifications) {" +
"if (window.webkitNotifications.checkPermission() == 0) { // 0 is PERMISSION_ALLOWED" +
" window.webkitNotifications.createNotification(" +
" 'icon.png', 'Notification Title', 'Notification content...');" +
" } else {\n" +
" window.webkitNotifications.requestPermission();" +
" } " +
"} else { " +
" console.log('no notifications')" +
"}");
Using vaadin 8
You tried with the old api, it hasn't been supported for many versions. The new api should work:
JavaScript.getCurrent().execute(
" if (!(\"Notification\" in window)) { " +
" alert(\"This browser does not support system notifications\"); " +
" } else if (Notification.permission === \"granted\") { " +
" new Notification(\"Hi there!\"); " +
" } else if (Notification.permission !== 'denied') { " +
" Notification.requestPermission(function (permission) { " +
" if (permission === \"granted\") { " +
" Notification(\"Hi there!\"); " +
" } " +
" }); " +
" } "
);
Can't say this is a good way to do it though.
There is a plugin for vaadin 7 https://vaadin.com/directory#!addon/webnotifications you can adopt it to 8. Or create a JavaScript component or at at least a JavaScript function that will make using it easier.
