Tried many time and many solution but all give me the same problem. Everything works just fine, the app works and no issues with it, it's just the shourtcut that is not being created on Desktop. I can see from the log files 'EmulateFileIOPermissionChecks' and a message error 'The given path's format is not supported.' but not sure what it means. I experienced the same error with this module "electron-squirrel-startup". Here is what is happening related to SquirrelSetup.log

I am trying to upsert document using below Stored Proc . I am passing different types of document in input having same partition key. Some if them are for create and some of them needs to be updated only if Etag matches. If e-Tag does not match my requirement is to throw exception from Stored Procedure which I need to handle in my Java code. Can someone please help me what changes I should make in below SP to handle that.
function createEvent(items) {
var collection = getContext().getCollection();
var collectionLink = collection.getSelfLink();
var count = 0;
if (!items) throw new Error("The array is undefined or null.");
var numItems = items.length;
if (numItems == 0) {
getContext().getResponse().setBody(0);
return;
}
tryCreate(items[count], callback);
function tryCreate(item, callback) {
var options = { disableAutomaticIdGeneration: false };
var isAccepted = collection.upsertDocument(collectionLink, item, options, callback);
if (!isAccepted) getContext().getResponse().setBody(count);
}
function callback(err, item, options) {
if (err) throw err;
count++;
if (count >= numItems) {
getContext().getResponse().setBody(count);
} else {
tryCreate(items[count], callback);
}

chrome.runtime.onMessage response with async await
(7 answers)
Closed 1 year ago.
I am having an issue of asynchronicity (I believe). sendResponse() in contentscript.js does not wait for getThumbnails() to return.
I am sending a message in popup.js:
chrome.tabs.sendMessage(tabs[0].id, {message: "get_thumbnails", tabUrl: tabs[0].url},
function (respThumbnails) {
const thumbUrl = respThumbnails.payload;
console.log("payload", thumbUrl)
}
);
Then, in contentscript.js I listen for this message:
chrome.runtime.onMessage.addListener(async function(request,sender,sendResponse) {
if(request.message === "get_thumbnails") {
const payload = await getThumbnails();
console.log("thumbPayload after function:", payload)
sendResponse({payload:payload});
}
});
async function getThumbnails() {
let tUrl = null;
var potentialLocations = [
{sel: "meta[property='og:image:secure_url']", attr: "content" },
{sel: "meta[property='og:image']", attr: "content" },
];
for(s of potentialLocations) {
if(tUrl) return
const el = document.querySelector(s.sel);
if(el) {
tUrl = el.getAttribute(s.attr) || null;
}
}
return tUrl;
};
But it is also possible that the problem is coming from my getThumnails() function, because most of the times, payload is null and not undefined. So getThumbnails() might return before it is completely executed.
If this is the case, I have no idea why...
I also tried this code for getThubnails():
async function getThumbnails() {
let x = await function() {
let tUrl = null;
var potentialLocations = [
{sel: "meta[property='og:image:secure_url']", attr: "content" },
{sel: "meta[property='og:image']", attr: "content" },
];
for(s of potentialLocations) {
if(tUrl) return
const el = document.querySelector(s.sel);
if(el) {
tUrl = el.getAttribute(s.attr) || null;
}
}
return tUrl;
}
return x;
};
But this does not work, it seems to break my code...
The callback of onMessage should return a literal true value (documentation) in order to keep the internal messaging channel open so that sendResponse can work asynchronously.
Problem
Your callback is declared with async keyword, so it returns a Promise, not a literal true value. Chrome extensions API doesn't support Promise in the returned value of onMessage callback until https://crbug.com/1185241 is fixed so it's just ignored, the port is immediately closed, and the caller receives undefined in response.
Solutions
Remove the async keyword from before (request, sender, sendResponse), then...
Solution 1
Call an async function that can be embedded as an IIFE:
chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
if (request.message === "get_thumbnails") {
(async () => {
const payload = await getThumbnails();
console.log("thumbPayload after function:", payload)
sendResponse({payload});
})();
return true; // keep the messaging channel open for sendResponse
}
});
Solution 2
Declare a separate async function and call it from the onMessage listener:
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
if (msg.message === "get_thumbnails") {
processMessage(msg).then(sendResponse);
return true; // keep the messaging channel open for sendResponse
}
});
async function processMessage(msg) {
console.log('Processing message', msg);
// .................
return 'foo';
}
I inherited a script to manage a deploy of Salesforce code to multiple orgs in one go, to ensure all orgs are on the same version. The code is maintained in a Github respository and the final step is the update of the main branch, so the deploy therefore has to be successful for all orgs before it updates the main branch. Currently we have 32 orgs for which the deploys run simultaneously (with more to be added).
The final step after the code has deployed successfully is to check all the Salesforce to Salesforce connections and mappings, since all the orgs update a 'hub' org. It is in this step that I've started getting Puppeteer timeouts. Sometimes it completes, sometimes it fails. It seems to be getting worse in that I have to rerun it 2 or 3 times to get it pass without timing out. I'm not experienced in Node or Puppeteer or scripts like these so don't know how to stop this happening. I've tried increasing the timeout from the default 30000 to 90000 but even then it fails sometimes so that is not a solution, obviously.
Interestingly a few of us have also been having problems lately with Chrome being dreadfully slow and timing out just in the browser (we run on the latest version of Chrome) and I read that Puppeteer uses Chrome. I tried googling but haven't found anything that helps me hence posting this query here.
I would appreciate any help to sort this out because running it multiple times for each deploy is not a viable solution, especially with the length of time it takes to complete.
This is the function from where it sets the timeout.
async function checkDifferencesForConnectionSafely(
argv: Config,
browser: Browser,
connection: Connection,
changes: SubscribedFieldUpdate[]
): Promise<void> {
const page = await browser.newPage();
page.setDefaultNavigationTimeout(90000); // added this but it still times out
try {
console.log(`Checking ${connection.username} -> ${connection.name}`);
await checkDifferencesForConnection(argv, page, connection, changes);
console.log(`Finished ${connection.username} -> ${connection.name}`);
} catch (e) {
console.log(`Failed ${connection.username} -> ${connection.name}`, e);
throw e;
} finally {
await page.close();
}
}
And this is the called function where I believe the timeout happens:
async function checkDifferencesForConnection(
argv: Config,
page: Page,
connection: Connection,
changes: SubscribedFieldUpdate[]
): Promise<void> {
await page.goto(connection.url);
const subscribedObjects = await getSubscribedObjects(page);
for (const object of subscribedObjects) {
await gotoObject(page, object);
const fields = await getSubscribedFields(page);
let changesMade = false;
for (const field of fields) {
field.isStrict = argv.strict;
if (field.selectedValueNeedsUpdate()) {
const newValue = field.newValue();
changes.push({
connection,
connectionObject: object,
connectionField: field,
newValue
});
await selectMapping(page, field, newValue);
changesMade = true;
} else if (!field.value) {
const options = field.options.map((o) => o.name);
throw new Error(
`No value for ${connection.name} -> ${object.name} -> ${field.name}, ` +
`options: ${options.join(", ")}`
);
}
}
if (!argv.skipPicklists) {
if (!argv.dryRun && changesMade) {
await saveSubscribedFields(page);
await gotoObject(page, object);
changesMade = false;
}
const pickListMappings = await getPicklistMappingLinks(page);
for (const pickListMapping of pickListMappings) {
try {
await pickListMapping.click();
} catch (e) {
console.log(
`Failed ${connection.username} -> ${connection.name} -> ${object.name} -> ${pickListMapping.id}`,
e
);
throw e;
}
const picklistValues = await getPicklistValues(page);
for (const picklistValue of picklistValues) {
picklistValue.isStrict = argv.strict;
if (picklistValue.selectedValueNeedsUpdate()) {
const newValue = picklistValue.newValue();
changes.push({
connection,
connectionObject: object,
connectionField: picklistValue,
newValue
});
await selectMapping(page, picklistValue, newValue);
changesMade = true;
}
}
await savePicklistMapping(page);
}
}
if (!argv.dryRun && changesMade) {
await saveSubscribedFields(page);
}
}
}
This is the error thrown (after running 2hrs 40min!)It is close to the end of the process so has completed most of the org checks at this stage. It doesn't always fail in the same place or on the same org checks so the timeout is not related to a specific connection.

This is the scenario I want:
I'm checking for the presence of an application (using protocol detection), if it's not present the exe file automatically starts downloading. The webpage continuously checks in regular interval whether the app has been successfully downloaded and when the installation is complete, the browser prompts to open the app.
What is working:
The download is starting automatically. The webpage is checking for the presence of the app in regular interval.
What is NOT working:
After the exe is downloaded, when I start the download, the focus shifts and the webpage thinks that the app has been launched, whereas the app actually hasn't yet been installed even.
I need a focus checking mechanism which detects when the specific app has been launched and focus shifts and not respond to any other focus shifts.
This is my code:
_registerEvent = function(target, eventType, cb) {
if (target.addEventListener) {
target.addEventListener(eventType, cb);
return {
remove: function() {
target.removeEventListener(eventType, cb);
}
};
} else {
target.attachEvent(eventType, cb);
return {
remove: function() {
target.detachEvent(eventType, cb);
}
};
}
},
checkIfHasProtocol = function($el) {
openUriWithTimeoutHack(url);
},
openUriWithTimeoutHack = function(protocol) {
var timeout = setTimeout(function() {
handler.remove();
checkIfHasProtocol(protocol);
}, 5000);
var target = window;
while (target != target.parent) {
target = target.parent;
}
var handler = _registerEvent(window, "blur", onBlur);
function onBlur() {
if (tabVisible() && isBlurred) {
clearTimeout(timeout);
handler.remove();
//App has been launched
}
}
}
window.location = protocol;
};
tabVisible(function() {
if (tabVisible() && inCheck) {
inCheck = false;
}
});
window.addEventListener("blur", function() {
isBlurred = true;
});
window.addEventListener("focus", function() {
isBlurred = false;
inCheck = false;
});
I do not know if this is possible but I might as well give it a chance and ask.
I'm doing an Electron app and I'd like to know if it is possible to have no more than a single instance at a time.
I have found this gist but I'm not sure hot to use it. Can someone shed some light of share a better idea ?
var preventMultipleInstances = function(window) {
var socket = (process.platform === 'win32') ? '\\\\.\\pipe\\myapp-sock' : path.join(os.tmpdir(), 'myapp.sock');
net.connect({path: socket}, function () {
var errorMessage = 'Another instance of ' + pjson.productName + ' is already running. Only one instance of the app can be open at a time.'
dialog.showMessageBox(window, {'type': 'error', message: errorMessage, buttons: ['OK']}, function() {
window.destroy()
})
}).on('error', function (err) {
if (process.platform !== 'win32') {
// try to unlink older socket if it exists, if it doesn't,
// ignore ENOENT errors
try {
fs.unlinkSync(socket);
} catch (e) {
if (e.code !== 'ENOENT') {
throw e;
}
}
}
net.createServer(function (connection) {}).listen(socket);;
});
}
There is a new API now: requestSingleInstanceLock
const { app } = require('electron')
let myWindow = null
const gotTheLock = app.requestSingleInstanceLock()
if (!gotTheLock) {
app.quit()
} else {
app.on('second-instance', (event, commandLine, workingDirectory) => {
// Someone tried to run a second instance, we should focus our window.
if (myWindow) {
if (myWindow.isMinimized()) myWindow.restore()
myWindow.focus()
}
})
// Create myWindow, load the rest of the app, etc...
app.on('ready', () => {
})
}
Use the makeSingleInstance function in the app module, there's even an example in the docs.
In Case you need the code.
let mainWindow = null;
//to make singleton instance
const isSecondInstance = app.makeSingleInstance((commandLine, workingDirectory) => {
// Someone tried to run a second instance, we should focus our window.
if (mainWindow) {
if (mainWindow.isMinimized()) mainWindow.restore()
mainWindow.focus()
}
})
if (isSecondInstance) {
app.quit()
}
