Actually one thing is the functionality of the /Experiment/Start-Stop button in status.html, but the other is 
the warning we get from mhttpd:

[mhttpd,ERROR] [mhttpd.cxx:1957:init_mhttpd_odb,ERROR] ODB "/Experiment/Start-Stop Buttons" is obsolete, please 
delete it.

This was added by KO on Nov. 29, 2019 (commit 2366eefc). So we have to decide re-enable this feature (and 
remove the warning above), or keep it dropped and work on changes of status.hmtl.

The epics frontend overwrites the "start command" odb after each start:

  // set start command in ODB
   midas::odb efe("/Programs/EPICS Frontend");
   std::string p(__FILE__);
   std::string s("build/epics_fe");
   auto i = p.find("epics_fe.cxx");
   p.replace(i, s.length(), s);
   p = p.substr(0, i + s.length());
   efe["Start command"].set_string_size(p, 256);

this should be set such that it only writes when the key is not there. It causes the following issue: on a pc with multiple experiments defined, you need to start the fe's with a "-e <name>" flag. 

Thanks for reporting this problem. It has been fixed today, so the start command is only written if it's emtpy.

Another small user experience request:

When making a link in the odb (web interface) a nice browser window pop's up. There is however not scrolling possible in the window. As a result, you can not reach a odb key if it is nested to deeply. 

Trying to type out the Link target in the field only allows for 32 characters

context: we are setting up a bunch of Links in the History

Thanks for reporting the bug with the pop-up not being able to scroll, I fixed that and committed the change.

I do however not understand the issue with 32 characters. The link NAME should not be more than 32 chars (which applies to all ODB keys). 
But if I try I can write more than 32 chars in the link target.

The JavaScript function

mjsonrpc_db_save / mjonrpc_db_load

have been dropped from the API because they were not considered safe. Users 
should use now the new function

file_save_ascii()

and

file_load_ascii()

These function have the additional advantage that the file is not loaded 
directly into the ODB but goes into the JavaScript code in the browser, which 
can check or modify it before sending it to the ODB via mjsonrpc_db_paste(). 

Access of these functions is limited to <experiment>/userfiles/* where 
<experiment> is the normal MIDAS experiment directory defined by "exptab" or 
"MIDAS_DIR". This ensures that there is no access to e.g. system-level files. If 
you need to access a directory not under "userfile", us symbolic links.

These files can be combined with file_picker(), which lets you select files on 
the server interactively.

Hi,

I was playing with MIDAS devel branch and I realized that
if I set an ODB INT32 key to a value using new ODB web interface 
it is reported in parenthesis always as (0xFFFFFFFF);

I tested with different browser and result is the same while this 
never happens in OldODB web interface...

Thanks for reporting this bug, I fixed it in the last commit.

Best,

Hi,
I just tested it and it works as expected !

Thanks,
