 28 May 2019, Stefan Ritt, Info, MIDAS switching to Cmake
|
Great news! I got convinced by some colleagues to switch midas to Cmake. After spending about one day, I wrote some initial CMakeLists.txt file and am so
excited about the advantages that I regret
not having done this step much earlier. Here is some information:

17 Jun 2019, Stefan Ritt, Bug Fix, removed modbset() from mhttpd.js
|
I disagree. The modbset() function is used in many custom pages at PSI because people are tired of typing mjsonrpc_db_paste([path],[value]) vs. modbset(path,
value). We need to keep
modbset() which is well documented at

|
A ladder of promise event handlers is certainly one possibility to enforce the order of ODB writes, but I wonder if we could so something simpler:
- modbset creates an object remembering the status of the RPC request. Initially, this object receives the status "open request"

Just to make this point clear: The "write-to-odb-read-via-hotlink" was never meant to guarantee the receiving side to see each change. If changes happen
too often, updates might get lost. If one relies on the
sequence of updates, one should use direct RPC calls to the frontend or use a midas buffer and encode updates in events.

Update: "make" instead of "make linux32" should also work. I believe the "linux32" target came
from some special case at TRIUMF for some FPGA embedded linux, which is not applicable for
the Raspberry Pi.

Note that the example experiment compiles a simple example frontend and a root-based analyzer. If you don't have
ROOT installed, you of course cannot compile the analyzer. If you don't need the analyzer, remove it from the
Makefile/CMakeLists.txt

Sure some existing scripting languages can be used, but they fall short of a few important items in larger experiments:
- they are typically run from a local terminal in the counting house. A remote observer of the experiment has no idea which script is running and at which |

Calling odbedit -c ... ist certainly not the most effective way, but it works. I just tried on my Mac and found that I can call odbedit about 150 times |

The bug has been fixed. It was actually in the mxml library. So you have to go to the midas/mxml
subdirectory and update that one via "git pull origin master".
