-------------------------------------
Summary: Thrift Erlang Library: Multiple thrift applications in
one bundle
Key: THRIFT-2528
URL: https://issues.apache.org/jira/browse/THRIFT-2528
Project: Thrift
Issue Type: Bug
Components: Erlang - Library
Reporter: Alexey Radkov
Priority: Minor
Attachments: thrift-appreg.patch
Probably this is rather a wish than a bug. Also i found the multiplex task for
Erlang [https://issues.apache.org/jira/browse/THRIFT-2110] that relates to this
but seems to be slightly different.
I need two thrift applications running in one bundle: a library API, say
_rsappapi_ and a test API _rstestapi_: the former is needed to set up the
library API configuration via thrift calls. Currently it is not feasible
because thrift application registers in {{start_link()}} with predefined name
in {{lib/erl/src/thrift_server.erl}}:
{code}
gen_server:start_link({local, ?SERVER}, ?MODULE, {Port, Service,
HandlerModule}, []).
{code}
and i got {{already_started}} exception:
{noformat}

I attached a patch that fixes this issue for me. It just replaces constant
{{?SERVER}} with the variable {{Service}} which normally has well-distinguished
name like _tSomeService_thrift_ and should not mess in Erlang applications
names.
