What do you mean by dead locks ?

Studio reformats some class parts, such as Methods defenitions when you save it.

But as I know feature Atelier, stores class definition as is, so you do not need more such option, just format class as you need, and it should keep so.

As I've already had some experience in such systems in production, and one of our projects, has similar architecture exclude docker, just on windows, some physical servers with ECP-Client + CSPGateway + Apache, and one HAPorxy server for all of this server. And in this case all this scheme is quite static, and adding new ECP-client means some manual works, on all levels. But with docker I expect, just call something like this command 

docker-compose scale ecp=10

and just get some new working instances, which just after gets their new web-clients

To work it as microservices and split CSPgateway and Cache instance as different containers, I need to have simple package just only with CSPGateway, but FieldTest versions does not contain it. But yes sure, I think it is good way too, and in this case I can have more WEB-containers then Cache does, if it would be needed.

Timur, you can look at my example at github which I wanted to use in to article about using docker but have not managed yet. In this example I have Dockerfile for ECP-client, which can be build for particular ECP-server. And with %Installer manifest possible to make backward data channel too, while we have already known about where our server placed, we can connect to him via %Net.RemoteConnect or something else and make new backward connection, the problem is in this case how to remove old ones. I played only on one machine. But in anyway, Ansible still could be useful, but in case to prepare servers to work in docker cluster,  which should be prepared before we could use docker-compose and so on. And My example also contains web-server (apache), to have an access to this new instance. What I wanted to do then is to use some load balancer, HAProxy or traefik (as recommended Luca), to get one point access to my application, and dynamically expandable, without any manual operations, except scaling.

Yes, such language extension is very useful, but there is one more feature less known, and unfortunately completely undocumented. Its structured system variables, some of them could me familiar it is: ^$JOB,  ^$LOCK, ^$GLOBAL and ^$ROUTINE. More information in documentation here. But not all knows that it is possible to make your own such global. You should create routine with name SSVN"global_name" in %SYS namespace, for example SSVNZA for ^$ZA global

and for example with this code below, you SET, GET, KILL any values in this global, and this global will contain individual data for every session, and it is possible to use $order or even $query for  such global

ROUTINE SSVNZA
#define global $na(^CacheTemp.ZA($select($isobject($get(%session)):%session.SessionId,1:$job)))

fullName(glob) {
    set global=$$$global
    for i=4:1:glob set global=$na(@global@(glob(i)))
    quit global
}
set(glob, value) public {
    set global=$$fullName(.glob)
    set @global=value
}
get(glob) public {
    set global=$$fullName(.glob)
    quit @global
}
kill(glob, zkill=0) public {
    set global=$$fullName(.glob)
    if zkill {
        zkill @global
    } else {
        kill @global
    }
}
order(glob, dir) public {
    set global=$$fullName(.glob)
    quit $order(@global, dir) 
}
query(glob, dir) public {
    set global=$$fullName(.glob)
    set result=$query(@global, dir)
    quit:result="" ""
    set newGlobal=$name(^$ZA)
    for i=$ql($$$global)+1:1:$ql(result) {
        set newGlobal=$name(@newGlobal@($qs(result,i)))
    }
    quit newGlobal 
}

But as I said before, as it is completely undocumented feature a bit difficult to get complete compatibility with ordinary globals. But it still could be useful, in other cases, like it used by InterSystems.

if $data(^$JOB($zparent))=0 write "Parent is gone"

Stefan had already answered, and you can find his answer here

ToPhone(s = "")
{
 set r=""
 set c=96 
 for p=2:1:9 {
     set k="" 
     for j=1:1:3+(p=7)+(p=9) { 
         set k=k_p
         set c($c($i(c)))=k
     }
 } 
 for i=1:1:$l(s) { 
     set n=$g(c($e(s,i)),0) 
     if $e(n)=$e(r,*) set r=r_" " 
     set r=r_n
 } 
 quit r
}

and 149, with a little bit changes

ToPhone(s = "")
{
 s r="",c=96 f p=2:1:9{s k="" f j=1:1:3+(p=7)+(p=9) s k=k_p,c($c($i(c)))=k} f i=1:1:$l(s){s n=$g(c($e(s,i)),0) s:$e(n)=$e(r,*) r=r_" " s r=r_n} q r
}

Well, my code below

toPhone(s  = "") {
  s r="",c=96,p=1 f i=3,3,3,3,3,4,3,4{s:$i(p) k="" f j=1:1:i s k=k_p,c($c($i(c)))=k} f i=1:1:$l(s){s n=$g(c($e(s,i)),0) s:$e(n)=$e(r,*) r=r_" " s r=r_n} q r
}

In first I'm generate a plane array with all variants, and then just get all numbers from it, include space between identical numbers, and zero for unknown symbols such as space

too close to my variant, but without listbuilds :)

I think I let other's to share their size, and tomorrow or sometime later I can share it.

My result is 157 :)

Actually, XData content it is a just XML, in it is stored exactly as you wrote it in IDE. But it is possible to compile any XData to any other format as you need, at this portal you can find two articles about how to do it, first and second. In your case it could be much easier, like some method which in compile mode gets all XData content and place it to &html<>, which then compile again as usual, and what you need after it is just call this generated method, to show this html. 

It's is not good idea, not all time and not everywhere I have an access to google, but I have an access to my installation, and I have to search on my local machine. And such search should be support browser's search engines. And then I could do something like this.

with settings

But Ensemble documentation, should provide their own search engine to install in my browser without any manual operations. As it possible to do with AddSearchProvider

Many times I need to get some link from documentation, to show particular part to someone. And some time it is quite difficult to get such link, and the worst place in Class References, where I can't get good link for a particular part of class.

So, what I need is, an active icon with link, which then I can use, and for Class reference too.

As an example github.

As for me, when I have to investigate some strange behavior in my application, I prefer to read all journal files or limited by time, and then all records, and then I have some some to find exactly what I need, like only kill records or only sets, and only for some concrete global references. So, my usual code looks like this:

     set exit=0
    set docId="14105401"
    set jrnFile=##class(%SYS.Journal.System).GetCurrentFileName()
    do {
        w !!,jrnFile,!
        set jrn=##class(%SYS.Journal.File).%OpenId(jrnFile)
        quit:'$isobject(jrn)
        
        #dim rec As %SYS.Journal.Record = jrn.FirstRecord
        set last=jrn.End
        set pr=0,opr=0
        do {
            set pr=$j(rec.Address/last*100,0,2)
            if pr'=opr write $c(13),pr_"%" set opr=pr
            
            if rec.%IsA("%SYS.Journal.SetKillRecord") {
                set glb=rec.GlobalNode
                if $qs(glb, 0),"^My.Global",$qs(glb, 1)=docId {
                    w !!,rec.Address,!,glb
                    w !
                }
            }
            
            set rec=rec.Next
            read q:0 set exit=q="q"
            quit:exit
        } while $isobject(rec)
        quit:exit
        
        set sc=jrn.GetPrev(jrnFile, .jrnFile)
    } while $$$ISOK(sc)
    quit

This code looks all journal files, file by file from latest to oldest, and show progress for current journal file, and shows offset if it found something interesting

In my opinion, it's more looks like by mistake, not sure why it could be done in other ways, it still working, with some limitations but any way.
We can wait what would say InterSystems, may be they will fix it in future.
