When I run cpython with the -X showrefcount flag on an extension I'm writing, it reports a negative reference count (e.g. [-5538 refs, 13503 blocks]) when I return None from a function (using the Py-RETURN_NONE macro).

• The exact count varies between runs, but remains within the same order of magnitude.
• Whatever is happening, it seems to happen slowly; I need to call the extension function approximately 50,000 times before the reference count goes negative.
• If we replace Py_RETURN_NONE; with Py_INCREF(Py_None); return Py_None;, it changes nothing. Indeed, we can seemingly add an arbitrary number of Py_INCREF(Py_None)s without affecting the reference count at all.
• If we replace Py_RETURN_NONE; with return Py_None; and don't increment the reference count, it segfaults (as expected).
• If we replace the None return with another value, e.g. PyLong_FromLong(0);, the problem vanishes.

What is the cause of this? Related question: why is the reference count not zero after running an empty script?

I am trying to set up a form in which buttons fill input fields and in which those input fields can again be emptied by other "delete" buttons.

This works quite well, but I cannot get rid of one problem in a special action sequence:

If I press buttons "one" and "three", the corresponding input forms are filled properly, this is what I want.

Now if after that I press the "Delete A" button, one of two unwanted things happen:

• If the command event.preventDefault() exists in line 15, then (only) the first input field gets cleared correctly and the buttons are restored. But when I then again press button "one", the complete form gets cleared and the word "three" vanishes from form 2.

• If the command event.preventDefault() is deleted from line 15, then as soon as I press "Delete A", the complete form gets cleared and also the word "three" vanishes from form 2.

I do not want to clear the complete form to be reloaded at any stage.

EDIT: The problem is not a question of returning false values from functions to prevent form submission as discussed in JavaScript code to stop form submission . in fact all my fucntions are returning falsevalues.

I´m using multiple external JavaScript-Files for the client- /frontend-Design of my Nuxt Application ( Nuxt Universal Mode, server-side rendering + client-side navigation ), putting them in the nuxt.config.js-file.

I am trying to learn Common Lisp with the book Common Lisp: A gentle introduction to Symbolic Computation. In addition, I am using SBCL, Emacs, and Slime.

By the end of chapter 10, on the advanced section there is this question:

10.9. Write a destructive function CHOP that shortens any non-NIL list to a list of one element. (CHOP '(FEE FIE FOE FUM)) should return (FEE).

This is the answer-sheet solution:

I have the following configuration in the manifest file -

I Have the following dataframe in R

In this example for multi-column sorting

Google Maps JS API began displaying blue focus border around the map after switching to another browser tab and then go back. Once the map is clicked the border vanishes.
The element with the border is generated by Gmaps and within their DOM. Border seems to show only in full-page map display.

Tracing Gmap DOM show a border at child of gm-style: (div.gm-style > div)

Okay, this is a very strange case of this "No secret key" error. I've looked at all the other answers related to this and none of them are related to my problem.
