This solution implements a new config variable MAX_ROWS, which corresponds to the “Maximum allowed rows to render CSV files. (0 for no limit)” and rewrites the Render function for CSV files in markup module. Now the render function only reads the file once, having MAX_FILE_SIZE+1 as a reader limit and MAX_ROWS as a row limit. When the file is larger than MAX_FILE_SIZE or has more rows than MAX_ROWS, it only renders until the limit, and displays a user-friendly warning informing that the rendered data is not complete, in the user's language. --- Previously, when a CSV file was larger than the limit, the render function lost its function to render the code. There were also multiple reads to the file, in order to determine its size and render or pre-render. The warning:
