That update action will create a new hash for the file, hence another counter will be created for the same file, same end result as (1) solution.

I do have the specification.

An .html page must retain its database counter value even if its:

(renamed && moved && contents altered)


[original attributes of the file]:

filename: index.html
filepath: /home/nikos/public_html/
contents: <html> Hello </html>

[get modified to]:

filename: index2.html
filepath: /home/nikos/public_html/folder/subfolder/
contents: <html> Hello, people </html>


The file is still the same, even though its attributes got modified.
We want counter.py script to still be able to "identify" the .html page, hence its counter value in order to get increased properly.
