Indeed that's the only reliable way to avoid caching across browsers. An alternative is
("&r=" + Math.random())
to add a random number.

Reloading JavaScript file NOT from the cache is really tricky these days. I added a
special Google Chrome extension to clear my browser cache, which works reliably:

Zaher Salman | Suggestion | embed modbvalue in SVG |
Is it possible to embed modbvalue in an SVG for use within a custom page?
thanks. |

Stefan Ritt | Suggestion | embed modbvalue in SVG |
You can't really embed it, but you can overlay it. You tag the SVG with a
"relative" position and then move the modbvalue with an "absolute" position over
it:
<svg style="position:relative" width="400" height="100">
<rect width="300" height="100" style="fill:rgb(255,0,0);stroke-width:3;stroke:rgb(0,0,0)" />
<div class="modbvalue" style="position:absolute;top:50px;left:50px" data-odb-path="/Runinfo/Run number"></div>
</svg> |

Lars Martin | Suggestion | Time zone selection for web page |
The new history as well as the clock in the web page header show the local time
of the user's computer running the browser.
Would it be possible to make it either always use the time zone of the Midas
server, or make it selectable from the config page?
It's not ideal trying to relate error messages from the midas.log to history
plots if the time stamps don't match. |

I implemented a new row in the config page to select the time zone.
"Local": Time zone where the browser runs
"Server": Time zone where the midas server runs (you have to update mhttpd for that)
"UTC+X": Any other time zone
The setting affects both the status header and the history display.
I spent quite some time with "named" time zones like "PST" "EST" "CEST", but the
support for that is not that great in JavaScript, so I decided to go with simple
UTC+X. Hope that's ok.
Please give it a try and let me know if it's working for you.
Best,
Stefan |

Zaher Salman | Suggestion | embed modbvalue in SVG |
I found a way to embed modbvalue into a SVG:
<text x="100" y="100" font-size="30rem">
Run=<tspan class="modbvalue" data-odb-path="/Runinfo/Run number"></tspan>
</text>
This seems to behave better that the suggestion below.

Hi Stefan,
This is great, the UTC+x is perfect, thank you.

Francesco Renga | Suggestion | MYSQL logger |
Dear all,
I'm trying to use the logging on a mysql DB. Following the instructions on
the Wiki, I recompiled MIDAS after installing mysql, and cmake with NEED_MYSQL=1
can find it:
-- MIDAS: Found MySQL version 8.0.23
Then, I compiled my frontend (cmake with no options + make) and run it, but in the
ODB I cannot find the tree for mySQL. I have only:
Logger/Runlog/ASCII
while I would expect also:
Logger/Runlog/SQL
What could be missing? Maybe should I add something in the CMakeList file or run
cmake with some option?
Thank you,
Francesco |

I solved this, it was a failed "make clean" before recompiling. Now it works.
Sorry for the noise.

Joseph McKenna | Suggestion | Have a list of 'users responsible' in Alarms and Programs odb entries |
There have been times in ALPHA that an alarm is triggered and the shift crew
are unclear who to contact if they aren't trained to fix the specific
failure mode.
I wish to add the property 'Users responsible' to the ODB for Alarms and
Programs.
I have drafted what this might look like in a new pull request:
https://bitbucket.org/tmidas/midas/pull-requests/22/add-users-responsible-
field-for-specific
It requires changing of several data structures, I think I have found all
instances of the definitions so the ODB should 'repair' any of the old
structures adding in users responsible.
If 'Users responsible' is set, MIDAS messages append them after the message
in brackets '()'. If used in conjunction with the MIDAS messenger
(mmessenger), the users responsible can be 'tagged' directly.
I.e, for slack, simply set the 'users responsible' to <@UserID|Nickname>,
for mattermost '@username', for discord '<@userid>'. Note that discord
doesn't allow you to tag by username, but numeric userid
I have expanded char array in 'al_trigger_class' to handle the potentially
longer MIDAS messages. Perhaps since I'm touching these lines I should
change these temporary containers to std::string (line 383 and 386 of
alarm.cxx)?
I have tested this quite a bit for my system, I am not sure how I can test
mjsonrpc. |

I think this is a good idea and I support it. We have a similar problem in MEG and
we solved that with external (bash) scripts called in case of alarms. One feature
there we have is that for some alarms, several people want to get notified. So
people can "subscribe" to certain alarms. The subscription are now handled inside
Slack which I like better, but maybe it would be good to have more than one "user
responsible". Like if one person is sleeping/traveling, it's good to have a
substitute. Can you make an array out of that? Or a comma-separated list?
Best,

Presently there are 256 characters in the 'users responsible' field, so you can just
list many users (no space, space or comma whatever). Discord, slack and mattermost
don't care, they just parse the user tags.
I can still make this an array and pass a std::vector<std::string> into
al_trigger_class function? |

Maybe 256 chars are enough at the moment. If other people complain in the future, we can
re-visit.

Thinking about it, an array of maybe 80 character would give enough space for a name, a tag
and phone number. Do I need to budget memory very strictly? Would 32 entries of 80
characters be too much? |

On that level memory is cheap.

I've updated the branch / pull request to use an array of 10 entries (80 chars each). 32 felt a
little overkill when I saw it on screen, but absolutely happy to set it to any number you
recommend.
The array gets flattened out when an alarm is triggered, currently the formatting produces
AlarmClass : AlarmMessage (Flattened List Of Users Responsible Array With Space Separators)
If experiments want to use Discord / Slack / Mattermost tags and or add phone numbers, that
should fit in 80 characters |

This list of responsible being attached to alarm message strings will be great for the
mmessenger, however, perhaps its going to generate very long messages for the speaker programs
(web interface and mlxspeaker ):
AlarmClass : AlarmMessage (ResponsibleUser1 ResponsibleUser2 ResponsibleUser3 ResponsibleUser4
... ResponsibleUser4)
especially if people put in user tags or emergency contact details...
Should we add a key word or character for the programs that create audio to parse that silence
the list of responsible users? I'd be tempted to use a single character but there is a risk
users might have that in a custom alarm message. Maybe something usual like the 'bel'
character? '|'?
Perhaps use the string 'Responsible:' or 'Users:' to trim out the Users Responsible list from
the message string?
AlarmClass : AlarmMessage Responsible:(ResponsibleUser1 ResponsibleUser2 ResponsibleUser3
ResponsibleUser4 ... ResponsibleUser4)
AlarmClass : AlarmMessage Users:(ResponsibleUser1 ResponsibleUser2 ResponsibleUser3
ResponsibleUser4 ... ResponsibleUser4) |

This is a great idea. But I think we do not need to artificially limit ourselves
to string and array lengths.
The code in alarm.c should be changes to use std::string and std::vector<std::string> (STRING_LIST
#define), db_get_record() should be replaced with individual ODB reads (that's what it does behind
the scenes, but in a non-type and -size safe way).
I think the web page code will work correctly, it does not care about string lengths.

Ok, I'm working on this... I see a design choice to make, 1. Keep 'ALARM' as a struct, or 2. Replace ALARM struct with a class (keeping memory layout the same). Since we are adding STRING_LIST, I'd lean towards a C++ style with a class
1. Keep 'ALARM' as a struct:
Get rid of ALARM_ODB_STR for the default values
Add static functions (that take a hkey) to interact with the ODB (to save duplicating logic in al_reset_alarm, al_check, al_define_odb_alarm and al_trigger_alarm)
2. Replace ALARM struct with a class:
default ctor: Do nothing special (so it behaves like the old struct)
default dtor: std::vector<std::string> dtor will
It seems an opportunity to convert the alarm struct to a class with member functions that take hkey pointers?
default ctor: Do nothing special (so it behaves like the old struct)
default dtor: std::vector<std::string> dtor will
SetToDefault: This is where default values are hard coded (functionally replace ALARM_ODB_STR ) |

Auto growing lists is an excellent plan. I am making decent progress and should have something to
report soon |
