Re: Re: [pgAdmin4][Patch][Feature #1971]: Remember column sizes between executions of the same query in the query tool

Hi Surinder!

We reviewed this patch. The changes look good and we especially like that
you have extracted out the new utility functions and the epicRandomString
function too.

This patch will likely affect the Query Results patch that is currently
under review
<https://www.postgresql.org/message-id/flat/CAAtBm9V-tNQrtjxt4n8JJek5M4v9KW_h3sgbL1ydcBB%2BtLus2w%40mail(dot)gmail(dot)com#CAAtBm9V-tNQrtjxt4n8JJek5M4v9KW_h3sgbL1ydcBB+tLus2w(at)mail(dot)gmail(dot)com>.
In order to assist either us or yourself when making a merge between these
patches, it would help to have jasmine unit testing for the two new
functions, getHash and calculate_column_width.

Also, we suggest that you rename calculate_column_width to
calculateColumnWidth for consistency with javascript code style.

Thanks,
Shruti and Matt
