Subject [jira] Commented: (DERBY-3447) Shutdown on a database without stopping replication hangs

V.Narayanan commented on DERBY-3447:
------------------------------------

Thank you for the inputs Oystein.

I have been single stepping this issue and will briefly try to describe my progress so far.

I tried calling the stopMaster() method from RawStore#stop() to check if this will help me
in determining if this would help result in a proper master shutdown. It did not.

I resorted to good old single stepping with my buddy Netbeans

I placed breakpoints in the following places

1) ij#quit() line no 342
2) TopService#shutdown() line no 327 (I did this after I did one round of single stepping
with 3) below)
3) MasterController#stopMaster() line no 262

I basically started ij with the following command

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009 org.apache.derby.tools.ij

and connected to it through netbeans

I basically observed the following when authentication is enabled

1) MasterController#stopMaster() is never called (called when authentication is not enabled)
2) TopService#shutdown() is never called with authentication enabled ( I tried this twice
and observed the
   same this. Shouldn't the modules that are currently loaded be shutdown when authentication
is enabled too?
   I am not sure how replication code can influence this.)

I need to basically take it from here. I decided to report because I thought maybe people
could guide me as to why TopService#shutdown() is not called with authentication enabled and
as to whether
this is something they know of?

TopService#shutdown() is however called when I do a connect 'jdbc:derby:;shutdown=true;user=oystein;password=pass';
