[Wrapper-user] Support SIGHUP Handling

[Yazbek, D. \(Daniel\) <dy...@av...>]

Hi all,

=20

We are attempting to modify wrapper so that a SIGHUP can be handled by
java code, I am after some help/suggestions.

=20

Here is what I've done so far:

=20

Modified WrapperManager.java with:

public static final int WRAPPER_CTRL_SIGHUP_EVENT    =3D 205;

Recompiled the code, javah added this definition into
org_tanukisoftware_wrapper_WrapperManager.h

=20

Modified wrapper_unix.c with:

-          added case in getSignalName(int signo)

-          written a handleHangup(int sig_num) function, with
deceleration:

void handleHangup(int sig_num) {

   =20

    /* Ignore any other signals while in this handler. */

    signal(SIGHUP, SIG_IGN);

   =20

    handleCommon("HUP");

   =20

    signal(SIGHUP, handleHangup);

}

-          Modified wrapperInitialize() to support SIGHUP

=20

Modified wrapperjni_unix.c with:

-          added a handleHandup(int sig_num) function:

void handleHangup(int sig_num) {

signal(SIGHUP, handleHangup);
WrapperJNIHandleSignal(org_tanukisoftware_wrapper_WrapperManager_WRAPPER
_CTRL_SIGHUP_EVENT);

}

-          Set the above handler for a SIGHUP in the init function

=20

So, I guess I am missing something. I cannot get the SIGHUP in the java
application from the controlEvent(int arg0) method of my class that
implements WrapperListener.

=20

However, when I send a sighup, I get "HUP Trapped" in the log file,
which is being generated by

handleCommon(const char* sigName)

=20

I am not familiar with the architecture and a newbie to wrapper...

Does anyone have any suggestions on where I should be heading towards
from here?

Thanks.
