QUESTION
Description:
I believe the work my Cloud Firestore Triggers are supposed to perform is being overwritten by each other. I am attempting to use a Cloud Firestore Trigger to handle adding data to firestore after specific webhooks from a 3rd party API are processed. The webhook is first handled by creating a new document in an events collection i.e. events/{event}. The incoming webhooks are processed correctly and an event document is created for each webhook received.
I then use an onCreate trigger to add data to a single document within a collection of documents called "courses" and each document has a subcollection of "chapters". Each event document (which triggers the onCreate) may point to either the course document or a chapter document. My function within the trigger (setMetadata) checks which of these two documents the event document is referencing and updates the required fields. Each of my tests consists of 1 course and 2 chapter (which are nested in the course document) documents to be updated (3 webhooks received and in turn 3 onCreate triggers) almost at the same exact time.
Problem:
The work, after the Cloud Firestore Triggers are completed, produces inconsistent results. Some attempts add the metadata to the course document but not the chapter documents, other times to the chapter documents but not the course. And finally very few times all documents are updated correctly. No errors are produced. I have attempted to use onWrite instead as well as update instead of set. How do I ensure all documents are updated accordingly? Is this a race condition with the triggers overwriting the previous work from another trigger?
Goal
The goal is to have every initiated trigger to correctly update the corresponding document's fields. Please let me know if I need to provide any further info or context.

Answered 2020-Sep-09 at 20:22Is this a race condition with the triggers overwriting the previous work from another trigger?
Yes, there is always the chance of a race condition. Cloud Functions does not guarantee an order of execution, and they could be executed in parallel. If you think that two invocations of a function have the possibility of interfering with each other, you should use a transaction to manage the results of that atomically.
QUESTION
I'm on macOS Mojave 10.14.6. My Qt version is 5.13.1. My Qt Creator version is 4.10.0.
When I set a breakpoint and run the application, the debugger never finishes and prints to the debugger log with the below error.
So, the wrong version of python for lldb is being used, from what I can gather. Is this a Qt Creator setting or a mac setting and how can I fix it?

I'm following the Singleton design pattern as described in this book (https://github.com/PacktPublishing/Go-Design-Patterns/blob/master/Chapter02/main.go) and I have this code in file "singleton2.go":
...ANSWER
Answered 2019-Jun-12 at 22:01Follow the logic of your code and it's apparent where the problem is.
When you declare, but do not initialize the singleton (var instance *singleton) then instance is nil. Calling GetInstance evaluates instance == nil as true and returns a new *singleton every time it is called. That is why counter2 will never equal expectedCounter - each call to GetInstance is returning a new counter instance.
When you initialize the singleton instance (var instance = &singleton{}) then calls to GetInstance will return that singleton instance since it is not nil.
I imagine you'd want to modify GetInstance to something like this:

Answered 2019-Feb-15 at 03:20The return you are seeing is correct because Chapter02a is a "relative" link to the next section. The full url is not listed because that is not how it is stored in the html.

Answered 2018-Jul-18 at 10:56The underlying iText 7 bug/peculiarity is the same as described in this answer where the table is built across four pages but all the fields turns up on the last page.
As you clarified, though, in a comment, you want the table and the fields on the last page anyways. Thus, all we need to do is move the table to the last page, too.
This actually is quite simple, merely add an appropriate AreaBreak before adding the table:
