Dario,

My mistake. GsExternalSession>>softBreak (and hardBreak) work correctly. They do, in fact, post an interrupt to the running process and the running process does, in fact, stop. In order to “catch” the break you need to follow the break with another waitForResult call. It should return immediately after you wait and the thing returned should be the break exception.

Dario,

GsExternalSession>>softBreak (and hardBreak) should have interrupted the non-blocking call. I’ve reported this as internal bug #47869.

Ciao, 
another points.


E) After a  aGsExternalSession forkString: 'DTRClient bigData'.

aGsExternalSession waitForResultForSeconds: 2  otherwise:[ ......  ]

If the remote system don't answer in the time and i  would like to finish the execution

what i can do in the otherwise block to terminate the call in progress ?

When i submit another request the system answer :   'call in progress' .

The   abort  -  softBreak  and  hardBreak   don't reset the     call in progress.

Thanks,

Dario


Ciao,

i do som test about External Sessions support between two Gemstone 3.4.3. system.

Some points:

A) The remote system ( presolana )need to have the same logs directory path  ( 
/opt/GsDKb/GsDevKit_home/server/stones/base_343/logs )
  of the request.
Otherwise the remote netldi.log report the entry:
For client command: '!#encrypted:party#netldi:39357#dir:/opt/GsDKb/GsDevKit_home/server/stones/base_343/logs#log:%N%P.log!gemnetobject'
    chdir(/opt/GsDKb/GsDevKit_home/server/stones/base_343/logs) failed in child process
    ERROR: errno=2,ENOENT, The file or directory specified cannot be found

B)  When create  the GsExternalSession  with the Network Resource String:
gemNRS: '!@25.58.122.207#netldi:41953!gemnetobject'

 UserGlobals at: #Sample put:
    ( GsExternalSession
    gemNRS: '!@25.58.122.207#netldi:41953!gemnetobject'
    stoneNRS: '!@25.58.122.207!base_343'
    username: 'DataCurator'
    password: 'swordfish'
    yourself).

the system report the error:

a MessageNotUnderstood occurred (error 2010), a String does not understand  #'node' (3)

C)  I login aGsExternalSession on remote system and all works fine.

But when i do the aGsExternalSession logout 

the system is blocked for 20 seconds and after open a dialog: 

UserDefinedError: session with stone session ID of 6 gemProcessId = 3115 still present 20 seconds after logout (3)

D) The exception it is not accessible, or at least it is not clear how to do it.
| result | 

result := [myGsExternalSession executeString: '1/0']

on: GciError
do: [:ex | ex description].

open a dialog with :  ArgumentError: NullPointer error, CByteArray.CData == 0 (3)

Thanks for considerations,

Dario
