 11 Feb 2020, Stefan Ritt, Suggestion, switch midas to c++ threads?
|
I'm thinking of this already since some time, and it was part of my motivation switching to C++11.
I was delighted to see that what we do in system.c (encapsulate system functions such as threads
and shared memory) is now done natively in C++11, and it's done by experts and not amateurs like us.

For a long time now we have keep the core of midas (odb.c, midas.c, etc) compatible with plain C and by default
we have built the MIDAS library using the plain C compiler. Over time, we have switched most MIDAS programs
(mhttpd, mlogger, mdump, odbedit, etc) to C++ (with happy results). (and for a long time now, all of MIDAS

Dear Konstantin,
even if I am still quite young and have only limited experience (but not null), I would like to give my two cents. I have reflected a bit about the C++ |

some semi-random thoughts:
no templates strictly means you can't use std::string, std::vector etc.

Dear Konstantin and others,
our recent discussion stimulated my curiosity and I wrote a small frontend for the trigger board of our experiment in C++.
The underlying hardware details are not relevant here. I would just like to briefly report and discuss what I found out.

Regarding odb dumps saved into the midas output files, there are several

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/."

We're using mhttpd for calls that end up working better with asynchronous requests, and we've built up sort of a parallel, asynchronous library using javascript
Promises.
