This has been resolved. See above for the solution. It is marked with a header saying solution.

• $filter to iterate loop of Series array
• $regexMatch to search format in seb
• $size to get total elements in filtered result

If you read the assembler code from the top you will see that it reaches .L3, plus it also jumps to it with jne .L3, which is your for loop in C.

• $filter to iterate loop of users array, check condition for "admin" is in roles array
• $map to iterate loop of above filtered result and return user field

Other than the usual suspects (process.exit(), or process termination/signal, or crash/hardware failure), are there any circumstances where code in a finally block will not be reached?

If the promise will resolve or reject in future then it should reach to the final block.

According to the MDN docs,

The finally-block contains statements to execute after the try-block and catch-block(s) execute, but before the statements following the try...catch...finally-block. Note that the finally-block executes regardless of whether an exception is thrown. Also, if an exception is thrown, the statements in the finally-block execute even if no catch-block handles the exception.

A promise is just a JavaScript object. An object can have many states. A promise object can be in pending state or settled state. The state settled can divide as fulfilled and rejected. For this example just imagine we have only two state as PENDING and SETTLED.

Now if the promise never resolve or reject then it will never go to the settled state which means your then..catch..finally will never call. If nothing is reference to the promise then it will just garbage collected.

In your original question you mentioned about a 3rd party async method. If you see that code, the first thing you can see is, there are set of if(..) blocks to determine the current OS. But it does not have any else block or a default case.

What if non of the if(..) blocks are trigger ? There is nothing to execute and you already returned a promise with return new Promise(). So basically if non of the if(..) blocks are triggered, the promise will never change its state from pending to settled.

And then as @Bergi also mentioned there are some codes like this. A classic Promise constructor antipattern as he mentioned. For example see the below code,

Based on @turivishal's comment. The query below solved the problem.

You should first use $unwind, and then $lookup. You can do it like this:

• $match to filter our Conversations where the requested userId is present in userIds arrays

• $unwind to deconstructs an userIds array field

• $match again to filter only requested userId

• $lookup to replace userId with actual User document

I did this in the end using the python library py2neo, and created the cypher query using python

It seems to be a bug with CentOS https://bugs.centos.org/view.php?id=18213

gdal requires poppler-0.67, which is missing from official repositories. It is however present in the raven-extras repo: https://centos.pkgs.org/8/raven-extras-x86_64/poppler-0.67.0-22.el8.x86_64.rpm.html

Or you can download it as is (arbitrarily named poppler0.67.rpm here) and use it when installing gdal.
