Subject: [PATCH 8/9] data_provider_be: got rid of duplicating SIGTERM handler

It was wrong to install two libtevent SIGTERM handlers both of which did
|
||
|
|
orderly_shutdown()->exit(). Naturally only one of the handlers was executed
|
||
|
|
(as process was terminated with exit()) and libtevent docs doesn't say
|
||
|
|
anything about order of execution. But chances are, be_process_finalize()
|
||
|
|
was executed first so default_quit() was not executed and main_ctx was not
|
||
|
|
freed.
|
||
|
|
|
||
|
|
Moreover there is just no reason to have separate be_process_finalize()
|
||
|
|
at all: default server handler default_quit() frees main_ctx. And be_ctx
|
||
|
|
is linked to main_ctx so will be freed by default handler as well.
|
||
|
