  2158   05 May 2021 Zaher SalmanForumm is not defined error
We had the same issue here, which comes from mhttpd.js line 2395 on the current git version. This seems to happen mostly when there is an alarm triggered or when there is an error message.

Anyway, the easiest solution for us was to define m at the beginning of mhttpd_message function 

let m;

and replace line 2395 with

if (m !== undefined) {

Hi Stefan,

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

  2156   26 Apr 2021 Zaher SalmanSuggestionembed 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.

They were never meant to work with the history. They were primarily implemented to put large 64-
bit data words into midas banks. We did not yet have a request to put these values into the ODB. 
Once such a request comes, we can address this.

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,

Ahh, could be that ss_kbhit() misbehaves if there is no keyboard, meaning that it is started in the background as a script. 
We never had the issue before, since all "standard" midas programs like mlogger, mhttpd etc. also use ss_kbhit() and they 
can be started in the background via the "-D" flag, but maybe the stdin is then handled differentlhy. 

So just remove the ss_kbhit(), but keep the break, so that you can stop your program via the web page, like

#include "midas.h"
#include "stdio.h"

int main() {
  cm_connect_experiment("", "", "logic_controller", NULL);

  do {
    int status = cm_yield(100);
    printf("cm_yield returned %d\n", status);
    if (status == SS_ABORT || status == RPC_SHUTDOWN)
      break;
  } while (TRUE);

  cm_disconnect_experiment();

  return 0;
}

Hi Ben,

I have followed your suggestions and the program still stops immediately. My status as returned from "cm_yield(100)" is always 412 (SS_TIMEOUT) which is fine. 
The issue is that, when run with the script button, the do-wile loop stops immediately because the !ss_kbhit() always evaluates to FALSE.

My temporary solution has been to let the loop run forever :)

Let me know what think. Thanks again!

Isaac

I think it would be useful to find the minimal example that exhibits this behaviour.

What happens if your logic controller code is simply the 17 lines below? What happens if you create another script button that only starts the logic controller, not any of the other programs? etc. Gradually re-add features until you hit the problem (or scream in horror if it breaks with 17 lines of C++ and a 1 line shell script).



#include "midas.h"
#include "stdio.h"

int main() {
   cm_connect_experiment("", "", "logic_controller", NULL);

   do {
     int status = cm_yield(100);
     printf("cm_yield returned %d\n", status);
     if (status == SS_ABORT || status == RPC_SHUTDOWN)
       break;
   } while (!ss_kbhit());

   cm_disconnect_experiment();

   return 0;

> This is indeed very curious, and I can't reproduce it on my test experiment. Can you redirect stdout and stderr from the logic_controller program into a file, to see how far the program gets? If it gets to the while loop at the end, then it would be useful to add some debug statements to see what condition causes it to exit the loop.

I have redirected stdout and stderr into a text file and I have attached it to this entry. From what the stdout says, it seems that the lambda
function gets called 4 times before the program disconnects from the experiment. Somehow the status must become SS_ABORT or RPC_SHUTDOWN.

> Are there any relevant messages in the midas message log about the program being killed? What's the value of "/Programs/logic_controller/Watchdog timeout"? 

There are no interesting messages in the midas.log and "/Programs/logic_controller/Watchdog timeout" is 10000 when I run the command from the terminal window.
What happens when you run it on your test experiment?

I'll try some more debugging.

Thanks for helping me out! Cheers.

This is indeed very curious, and I can't reproduce it on my test experiment. Can you redirect stdout and stderr from the logic_controller program into a file, to see how far the program gets? If it gets to the while loop at the end, then it would be useful to add some debug statements to see what condition causes it to exit the loop.

Are there any relevant messages in the midas message log about the program being killed? What's the value of "/Programs/logic_controller/Watchdog timeout"? 
  2145   12 Apr 2021 Isaac Labrie BoulayForumClient gets immediately removed when using a script button.
Hi all,

I'm running into a curious problem when I try to run a program using my custom 
script button. I have been using a script button to start my DAQ, this button 
has always worked. It starts by exporting an absolute path to scripts and then 
runs scripts, my frontend, my analyzer, and mlogger relative to this path.

I recently added a line of code to run a new script "logic_controller". If I run 
the script_daq from my terminal (./start_daq), mhttpd accepts the client and the 
program works as intended. But, if I use the script button, the logic_controller 
program is immediately deleted by MIDAS. It can be seen appearing in the status 
page clients list and then immediately gets deleted. This is a client that runs 
on the local experiment host.

What might be the issue? What is the difference between running the script 
through the terminal as opposed to running it through the mhttpd button?

I have added a picture of my simple script and the logic_controller code.

Any help would be greatly appreciated.

Cheers.

Isaac

  2144   09 Apr 2021 Lars MartinSuggestionTime 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.
  2143   05 Apr 2021 Konstantin OlchanskiInfoblog - convert mfe frontend to tmfe c++ framework
Result is here:
https://bitbucket.org/expalpha/chronobox_software/src/master/fechrono_tmfe.cxx

Original code is in fechrono.cxx. Not super pretty, but representative of most mfe-based frontends
we see around here. A good example of why the old mfe.c structure no longer works so well for us.

After conversion to tmfe, we do not win a beauty contest yet, but the path for further
clean up and refactoring into better c++ is quite clear. (And it is very obvious where
the missing "event object" wants to be here)

  2142   05 Apr 2021 Konstantin OlchanskiInfoblog - convert mfe frontend to tmfe c++ framework
notes from converting ALPHA-g chronobox frontend fechrono to tmfe c++ framework.

the chronobox device is a timestamp/low resolution tdc/scaler/generic TTL and ECL io
mainboard with an altera DE10_NANO plugin board. it has a cyclone-5 FPGA SOC running Raspbian linux.
FPGA communication is done by avalon-bus memory mapped registers, main data readout
is PIO from an FPGA 32-bit wide FIFO (no DMA yet).

this created an incompatibility with old XML save files,
old versions of midas cannot load new XML save files,
variable types have changed i.e. from "INT" to "INT32".

it would have been better if XML save files kept using the old names.

now packages that read midas XML files also need updating.

specifically, in ROOTANA:
- the old TVirtualOdb/XmlOdb.cxx (no longer used, deleted),
- mvodb/mxmlodb.cxx

  2140   04 Apr 2021 Konstantin OlchanskiInfobk_init32a data format
In April 4th 2020 Stefan added a new data format that fixes the well known problem with alternating banks being 
misaligned against 64-bit addresses. (cannot find announcement on this forum. midas commit 
https://bitbucket.org/tmidas/midas/commits/541732ea265edba63f18367c7c9b8c02abbfc96e)

This brings the number of midas data formats to 3:

bk_init: bank_header_flags set to 0x0000001 (BANK_FORMAT_VERSION)
bk_init32: bank_header_flags set to 0x0000011 (BANK_FORMAT_VERSION | BANK_FORMAT_32BIT)
bk_init32a: bank_header_flags set to 0x0000031 (BANK_FORMAT_VERSION | BANK_FORMAT_32BIT | BANK_FORMAT_64BIT_ALIGNED;

TMEvent (midasio and manalyzer) support for "bk_init32a" format added today (commit 
https://bitbucket.org/tmidas/midasio/commits/61b7f07bc412ea45ed974bead8b6f1a9f2f90868)

TMidasEvent (rootana) support for "bk_init32a" format added today (commit 
https://bitbucket.org/tmidas/rootana/commits/3f43e6d30daf3323106a707f6a7ca2c8efb8859f)

ROOTANA should be able to handle bk_init32a() data now.

TMFE MIDAS c++ frontend switched from bk_init32() to bk_init32a() format (midas commit 
https://bitbucket.org/tmidas/midas/commits/982c9c2f8b1e329891a782bcc061d4c819266fcc)

NIH at work. In C and C++ the standard fixed bit length data types are available
in #include <stdint.h> as uint8_t, uint16_t, uint32_t, uint64_t & co.

BTW, the definition of UINT32 as "unsigned int" is technically incorrect, on 16-bit machines
"int" is 16-bit wide and on some 64-bit machines "int" is 64-bit wide.
