Hi -
I mentioned this issue at the NYCJUG meeting last night and am not sure I
was believed: when I fork a process from J7 jconsole, the forked process
affects the environment of the forking session. Here's a simple example -
I'd like to know if other people see the same issue in different OSs:
'FOO=: 1' fwrite 'testFork.ijs'
7
FOO=: 0
JEXE=: 'C:\Program Files (x86)\j64-701\bin\jconsole.exe ' NB. Windows 7
FOO
0
fork JEXE,'testFork.ijs'
FOO
1
fork
fork_jtask_
fork_jtask_
3 : 0
0 fork y
:
ph=. CreateProcess y
if. x do. Wait ph;x end.
CloseHandle ph
empty''
)
JVERSION
Engine: j701/2011-01-10/11:25
Library: 7.01.052
Platform: Win 64
Installer: j701a_win64.exe
InstallPath: c:/program files (x86)/j64-701
This doesn't happen in J6 - "FOO" stays assigned to zero. Also, if I
ensure that the forked process signs out, "FOO" retains the value assigned
in the invoking session:
('FOO=: 1',LF,'2!:55 ''''') fwrite 'testFork.ijs'
16
FOO=: 0
fork JEXE,'testFork.ijs'
|value error: JEXE
| fork JEXE,'testFork.ijs'
NB. "JEXE" no longer exists because my earlier "fork" created a new
environment in which it's not defined.
JEXE=: 'C:\Program Files (x86)\j64-701\bin\jconsole.exe ' NB. Windows 7
FOO
0
fork JEXE,'testFork.ijs'
FOO
0
