For interfacing to MIDAS just from browser javascript, the user does not need to know anything about JSON-RPC, all the user-level mjsonrpc_xxx() functions |

|
If using a synchronous AJAX call, such as "foo=ODBGet("/runinfo/state");", google chrome will prints this to the javascript console:
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/."

The JSON RPC branch has been merged into main MIDAS. Other than adding new functions, there are no changes to existing MIDAS functionality.
This is the current JSON RPC schema: (from the MIDAS Help page)

I updated the links on the midas wiki to the doxygen-generated documentation for MIDAS that you
get after running "git clone midas; cd midas; make dox; firefox html/index.html".

Not clear on what you are doing, so here is the brief description:
- you have two machines - say "midas" and "frontend"

The final bits of the JSON-RPC API to MIDAS are committed. The API uses the Javascript Promise mechanism (supported on all
supported platforms - MacOS, Windows, Linux Ubuntu, el5, el6, el7).

Here is example conversion of the function "generate midas message" from old-style AJAX to JSON-RPC:

28 Jan 2016, Konstantin Olchanski, Suggestion, script command limited to 256 characters; remove limit?

Thank you for reporting this problem:
a) ODB key *names* are restricted to 31 characters (32 bytes, last byte is a NUL), not 256 characters.
