Daily trace summary AJAX action field can contain commas

[bobbingwide]

The following line in the daily trace summary file from oik-plugins.co.uk for 20200209 has a AJAX action which contains unescaped commas.

/plugins/download/?plugin=oik-bwtrace-debug-trace-for-wordpress&version=3.0.0-RC2&id=37451&action=download.%2C%29%2C%29%27%29%29%22%27,download.,),)'))"',0.340538,7.3.14,1726,4709,400,44,464,57,34,20,19,0.010370969772339,,,,7588,45.227.255.149,0.340430,2020-02-09T02:15:51+00:00,Opera/9.80 (Windows NT 5.2; U; en) Presto/2.2.15 Version/10.00,GET

This causes problems for post processing of the daily trace summary files.

I've changed the code to detect a comma in the action. If present it wraps the action in double quotes
AND applies urlencode() against the action.

"/wordpress/plugins/download/?plugin=oik-bwtrace-debug-trace-for-wordpress&version=3.0.0-RC2&id=37451&action=download.%2C%29%2C%29%27%29%29%22%27,download","download.%2C%29%2C%29%5C%27%29%29%5C%22%5C%27%2Cdownload",2.126263,8.3.3,1285,4642,475,42,779,28,43,27,11,0.015740156173706,C:/apache/htdocs/wordpress/bwtrace3/bwtraces.loh.7,92,0,12043,127.0.0.1,2.126087,2024-09-17T16:12:44+00:00,Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML; like Gecko) Chrome/128.0.0.0 Safari/537.36,GET,200

Having made the change I ran slog.
The original output caused slog to produce a Too many columns message.

Count: 45 Too many columns: "/wordpress/plugins/download/?plugin=oik-bwtrace-debug-trace-for-wordpress&version=3.0.0-RC2&id=37451&action=download.%2C%29%2C%29%27%29%29%22%27,download",download.,),)'))"',download,2.336032,8.3.3,1285,4642,484,42,790,28,43,27,13,0.082084655761719,C:/apache/htdocs/wordpress/bwtrace3/bwtraces.loh.3,92,0,12129,127.0.0.1,2.335801,2024-09-17T16:00:00+00:00,Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML; like Gecko) Chrome/128.0.0.0 Safari/537.36,GET,200

I edited the daily trace summary and ran it again.
The change appears to have resolved the problem.

Note: the download/plugins request is interpreted by oik-plugins as an AJAX request. See oikp_lazy_redirect().
In this function, if DOING_AJAX is not already defined ( which is expected to be the case ) then it defines DOING_AJAX as true.
This doesn't happen until after tracing has been invoked, which explains why the trace file for the request is suffixed .log.n rather than .ajax.n

To support PHP 8.n we need to change the default value of action to an empty string, otherwise strpos() and urlencode() produce messages.
