I have a fe, with 2 "equipments" (2 different types of LV supplies).

Equipment/../Setting has a "Names" key, with the actual channel names (ch1, ch2, ...) of the devices.

Equipment/../Variables has channel states, voltage, etc. 

I also write a separate midas bank for each supply.

When I turn the "Log History" on, 2 things happen which cause troubles:
1. It writes the data of both bank to both the /Equipment/(Device1/Device2)/Variables .
2. I have e.g. 4 channels. In the banks I write current and voltages, so 8 numbers. When I turn on the logger I get an "Array size mismatch" between names and the midas bank size.

The only way around this is to disable the history logging in the equipment, and set "virtual" History events?

First, the writing of banks is completely independent of the history system. Banks go to the log file only, 
while the history is only linked to the "Variables" section in the ODB.

Second, it's advisable to group similar equipment into one. Like if you have five power supplies powering
and experiment, you don't want to have five equipments Supply1, Supply2, ..., but only one equipment
"Power Supplies". In the frontend belonging to that equipment, you define a DEVICE_DRIVER list with
one entry for each power supply. If you interact with an mscb device, there are some helper functions
which simplify the definition of the equipment and which I can send you privately. So your device
driver looks a bit like the one attached.

If you cannot do that and absolutely want separate equipments, please post a complete ODB subtree of your
settings, and I can try to reproduce your problem.

}

I wanted to have a c++ style driver, e.g. a instance of a "PowerSupply" class. This was not compatible with the list of DEVICE_DRIVER structs, with needs a C function entry point with variable arguments. 

Anyways, I attach my odb. I believe the issue stands regardless of the specific design choice here. Setting the History Log flag copies the banks created to the "Variables" of every equipments initialized, leading to a mismatch between the names array, and the variables. Can be solved by not using FE history events, but Virtual, but the flag in the Equipment is confusing.  

Bank creation in readout function:

for(const auto& d: drivers)
{
...
...
  bk_create(pevent,bk_name, TID_FLOAT, (void **)&pdata);
...			
  std::vector<float> voltage = d->GetVoltage();
  std::vector<float> current = d->GetCurrent();
  for(channels)
  {
    *pdata++ = voltage.at(iChannel);
    *pdata++ = current.at(iChannel);
  }
  bk_close(pevent, pdata);
}

1. ok, so calling the same readout functions from different equipments is just a bad idea, my bad, no blame for Midas to write data from both bank to both odb trees ...

2. One needs the same amount of bank entries as the size of settings/names[] . Otherwise the "History Log" flag does not work. So just don`t us "names" but "channel names" or something. 

" Second, it's advisable to group similar equipment into one. Like if you have five power supplies powering
and experiment, you don't want to have five equipments Supply1, Supply2, ..., but only one equipment
"Power Supplies".  "

It would be nice if this also works with c++ style drivers, i.e. a instance of a class. I don`t now how one would give an entry point to the "DEVICE_DRIVER" struct then.

I think you are facing several problems:

a) mlogger does not clearly explain what history names will be used for which entries
in /eq/xxx/variables. "mlogger -v" almost does it, but we also need
"mlogger -v -n" to "show what you will do, but do not do it yet".

b) the mfe.c and the device class driver structure is very dated, tries to "do c++ in c". If it works for you,
certainly use it, but if it confuses you (as it confuses me), it probably only takes a few lines of c++
to replace the whole thing (minus the actual device drivers, which is the meat of it).

It think today, you face a choice:
- invest some time to understand the old device driver framework
- invest some time to do it "by hand" in c++, write your own device drivers (or use 3rd party drivers or snarf the "c" drivers from midas). Use the TMFE C++ frontend class if you go this route.

I would estimate that both choices are about the same amount of work.

K.O.

We kind of agreed to rewrite the slow control system in C++. Each device will have its own driver derived from a common base class implementing the general communication. The reason we need a "system" and not only a "hand-written" driver is because we want:

- glue many device drivers together for a single equipment
- have a dedicated readout thread for every device, in order not to block other devices
- have a common error reporting scheme working with several threads
- being able to disable/enable individual devices without changing the history system each time
- having a common naming scheme for all devices (like "enforce" /Equipment/<name>/Settings/Names xxx) which is needed by the history system
- ...

Will see when we have time for that.

The histories capture key events from 'r' 'u' 'y' and 'Escape' for various functions like rescaling etc. However, this also means that if we include an editable modbvalue and a history in the same custom page then changing the modbvalue to something that includes 'ruy' is not possible.

In mhistory.js we have

// Keyboard event handler (has to be on the window!)
window.addEventListener("keydown", this.keyDown.bind(this));

I am not sure why it "has to be on the window". For now, I am bypassing this issue by changing the event listener to "keyup" but maybe there is a more elegant solution for this. Adding the event listener to the div element that includes the history does not seem to work.

I could reproduce the problem. I see two options there:

1) We replace 'r' with 'Ctrl-r' etc. 

2) We change the history JS code not to process keyboard inputs if we are currently editing a value.

I added 2) to give it a try. It works fine for me. The additional code is

MhistoryGraph.prototype.keyDown = function (e) {
   // don't consume events if we are editing a value
   if (e.target.tagName === "INPUT")
      return;
   ...
}


Feedback is welcome.

Stefan

I agree with you, option 2 is better and works well. 
The only problem is that if you are showing multiple histograms in the same window the keyDown even will affect all of the histories in the window. 
This may be the intended behaviour, but I think that if we can find a way to have the event affecting only the intended history (focused element for example) it would be better.

The history panels are simple pictures from the perspective of the browser and have no concept of a focus. This would have to be tweaked somehow. If you want to reset a single history, 
just click on its reset button (circle arrow at the right top).

Stefan

is there a reason why histograms are not saved after a replay?

   /* save histos if requested */
   if (out_info.histo_dump && clp.online) {
                              ^^^^^^^^^^

perhaps the && should be ||?

The original reason for that is the for running online, you want some histos for
monitoring after each run. For running offline, you specify a root output file via
"-o xxx.root" which contains trees AND histos. So the histos would there be twice
if you remove the "clp.online" from above.

Having "-o xxx.root" is IMHO a cleaner way, since you might want to analyze a run
in different ways (like using different calibrations). So what you do is specify
different "-o cal00123.root", "-o final00123.root" and so on, while with the
mechanism in eor() you always get the same file name. So try using "-o xxx.root"
and see if that fits your needs.

To support IPV6, we need to migrate MIDAS from gethostbyname() to getaddrinfo(). (Thanks to 
http://www.openwall.com/lists/oss-security/2015/01/27/9). K.O.

Hi all,

Hi, yes, this is the right place to report problems and to ask questions about midas.

As for your trouble, I have the same macos 10.13.6, so we should be able to figure out what goes wrong.

Unfortunately, the posted instructions (to run cmake directly) hide all the information needed to debug build problems.

Instead of "cd build; cmake ..", please run "make cmake" and post the output. Printed should be all the compiler
and linker commands executed by the build. You can examine the mhttpd linker command to see if somehow
the wrong openssl library is being used.

If you do not need built-in https support in mhttpd, you can run "make cmake NO_SSL=1".

I tried on my Mac (macOS 10.14.6, Xcode 11.3.1, current develop branch, openssl 1.1.1d) and it woks fine. Below is the transcript. I 
see that your cmake output is much shorter (no C compiler listed etc.). Did you remove some lines? For such comparisons, it's 
always good to start with an empty build directory.

OpenSSL libraries are the same (1.1.1d). Just for comparison, I run the build process with "make VERBOSE=1" and extract the line 
which fails for you when linking mhttp, so maybe you can compare.

I get the same, libssl from /opt/local, so we are not using openssl shipped with mac os.

We still do not know were OP's libssl comes from and if there is a mismatch between
openssl header files and library (header files from one openssl, library from a different openssl).

OP's cmake output: (no VERBOSE=1)
> -- MIDAS: cmake version: 3.16.3
> -- MIDAS: Found OpenSSL version 1.1.1d

Stefan's and my cmake output: (VERBOSE=1)
> -- MIDAS: cmake version: 3.16.3
> -- Found OpenSSL: /opt/local/lib/libcrypto.dylib (found version "1.1.1d")  
> -- MIDAS: Found OpenSSL version 1.1.1d

Without VERBOSE=1 cmake does not tell is which OpenSSL it found (not useful).
With VERBOSE=1 cmake outputs a flood of gunk (not useful).

My solution is to filter the cmake output with grep in "make cmake" ("make cmake3").

So please use that: "make cmake" - the output is roughly the same as normal make - compiler command lines (CFLAGS, library paths, etc),
compiler error message and all of the useful cmake output.

K.O.

Hi all,

I have just compiled midas 4401 using SuSE 11.0.
gcc is some odd SuSE version:
gcc version 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036] (SUSE
Linux) 

Anyway, gcc stumbled over melog.c. I don't see the reason myself, but my
experience is that gcc is usually right when complaining about "array subscript
is above array bounds". So, just in case somebody knowlegeable wants to have a
look at this....

Cheers,

Randolf

The gcc output:

Sorry the previous message got mangled:

Hi, 
I think that rather than spending too much time on where to put files 
and how to define the environment - I am guilty of that myself -  we should 
perhaps have some discussion on the future of MIDAS. 

Are we ready for 2.0? 

Stefan - do you have any ideas/enhancements? 

1) For one I would like to explore memory mapping (mmap()) on Linux.
I've used it once upon a time on DEC OSF/1 and I found it really nice 
compared to shared memory. From a user standpoint it behaves as a shared
memory but is mapped to a real file that can be easily "removed" when 
neccessary. One really annoying thing in MIDAS is when it goes ballistic 
the cleanup is somewhat tricky. 
The question if there is any performance penalty associated 

2) Expanding hardware support: 
  a) custom microcontrolers? 
  b) other hardware
  c) how about a "standard" Linux device /dev/midas for various 
  PCI cards (PCI<->CAMAC) (PCI<->VME) 

3) I have never really seen a midas deployment that uses interrupts. 
I do understand the ease of polling and the fact that these days CPU's 
are cheap but sometimes it is important to use interrupts. 

Any examples/experience? 

?)
