memory exhausted (scan.php)

    In scan.php line 3.7.3 causes memory exhaustion:

    file_put_contents( NSCAN_TMP_SNAPSHOT, serialize( $snapshot ) );

    I think serialize is still problematic.
    Also not the whole snapshot should be saved at once. It should be one line per entry and maybe json_encode. See also my previous threads regarding possible improvements.

    The error happened after the NinjaScanner and NinjaFirewall plugins were installed (and a file manager) so it was caused by too many new files / changes. It also happens when the relevant scan folder is deleted in wp-content/ninjascanner.

    The actual error messages:

    Allowed memory size of 134217728 bytes exhausted (tried to allocate 1744455 bytes)

    05-Feb-22 22:13:22 ERROR Error: E_ERROR (Allowed memory size of 134217728 bytes exhausted (tried to allocate 1744455 bytes) - line 373 in /www/htdocs/wp-content/plugins/ninjascanner/lib/scan.php)

    A flat file in CSV format would solve those issues. I use that format for the Code Profiler plugin. It can deal with hundreds of MB of data without any memory issue.
    But that would be for the next major version of NinjaScanner, because there will be a lot of code to rewrite.

    Thanks, this approach sounds like an ideal solution.
