REQ: Status page to show minimum and maximum endtimes in program table

[Jonathan Martens <jonathan@…>]

At the moment the status page in MythTV shows the maximum endtime available in the program table, but I would like to suggest a improvement to make it a little more sane, as in some cases, like here in Holland, not all channels have the same amount of days in the future published (some only 3 days, where others might have 14 days of data ahead).

I therefore would like the query to be rewritten to the following:

SELECT 
  MIN(t1.per_chanid_endtime) min_endtime, 
  MAX(t1.per_chanid_endtime) max_endtime 
FROM ( 
  SELECT 
    chanid, 
    MAX(endtime) per_chanid_endtime 
  FROM program
  WHERE manualid=0 
  GROUP BY chanid
) AS t1;

This will list the minimum endtime as well as the maximum endtime like this:

mysql> SELECT MIN(t1.per_chanid_endtime) min_endtime, MAX(t1.per_chanid_endtime) max_endtime FROM ( SELECT chanid, MAX(endtime) per_chanid_endtime FROM program WHERE manualid=0 GROUP BY chanid) as t1;
+---------------------+---------------------+
| min_endtime         | max_endtime         |
+---------------------+---------------------+
| 2009-01-31 00:10:00 | 2009-02-12 09:00:00 |
+---------------------+---------------------+
1 row in set (0.12 sec)

This makes it more obvious (and earlier when there still is no problem) to the users whether there might be a problem with their grabber(s) compared to listing only the maximum like is done now.

Since I do not have too much coding skills I am not able to attach a patch at the moment, but I beleive changes should be made in MythFrontend as well as MythWeb.

I might be able to supply a patch for MythWeb soonish as I have PHP skills but my C skills are a bit rusty.

Should I raise a seperate issue for each or can we trac that using this bug?

Oops it seems the formatting of Trac is a little different in preview and actual view which makes the resultset not very readable, perhaps this is better:

mysql> SELECT MIN(t1.per_chanid_endtime) min_endtime, MAX(t1.per_chanid_endtime) max_endtime FROM ( SELECT chanid, MAX(endtime) per_chanid_endtime FROM program WHERE manualid=0 GROUP BY chanid) as t1\G * 1. row * min_endtime: 2009-01-31 00:10:00 max_endtime: 2009-02-12 09:00:00 1 row in set (0.00 sec)

[Jonathan Martens <jonathan@…>]

Nope, retrying with a few extra newlines: mysql> SELECT MIN(t1.per_chanid_endtime) min_endtime, MAX(t1.per_chanid_endtime) max_endtime FROM ( SELECT chanid, MAX(endtime) per_chanid_endtime FROM program WHERE manualid=0 GROUP BY chanid) as t1\G

* 1. row *

min_endtime: 2009-01-31 00:10:00

max_endtime: 2009-02-12 09:00:00

1 row in set (0.00 sec)
