Folsom fails to start for host in MongooseIM

[kjw1]

I'm not sure if this is an issue with MongooseIM or folsom, but I get this error when running master, whereas I don't get it when running tag 0.8.1. I don't have any more info than that, unfortunately.

hi, mod_metrics is part of mongooseIm

[kjw1]

I guess there must be some API incompatibility, though, otherwise changing the version of folsom I was using wouldn't have made a difference. If that's expected, all well and good, just wanted to report it in case that wasn't intentional.

[linearregression]

Hi, Would be nice of more info is provided other than just the error What is version of MongooseIM? Had that work before but not anymore after any version change on either Folsom and/or MongooseIM? If so, the versions? Associated Configs for set? Steps to reproduce?

[hspecter]

I have the same problem, version of MongooseIM is HEAD, actually I tryed to start MongooseIM 1.3.2 and 1.4.0 versions of server and got ->

Steps for reproduce are simple: Clone newest version MongooseIM and change $PROJECT/rebar.config from {folsom, ".", {git, "git://github.com/boundary/folsom.git", "4824aec693c7f284363f19d999289952ec4ed586"}}, to {folsom, ".", {git, "git://github.com/boundary/folsom.git", "0.8.1"}}, thats include bear as app and after $ make && make rel start server $ rel/mongooseim/bin/mongooseimctl live

[benoitc]

The issue is due to the way bear is added to the folsom application. it should be really added to the included_applications not applications. A temporary patch for mangooseim is:

Hi, Next problem I meet when starting MongooseIM with mod_metrics:

Problem appears when we have in

ejabberd.cfg

that ->

%%%'   SERVED HOSTNAMES
%% hosts: Domains served by ejabberd.
%% You can define one or several, for example:
%% {hosts, ["example.net", "example.com", "example.org"]}.
%%
{hosts, ["publicname", "publicname2"] }.

and disappears when we have ->

%%%'   SERVED HOSTNAMES
%% hosts: Domains served by ejabberd.
%% You can define one or several, for example:
%% {hosts, ["example.net", "example.com", "example.org"]}.
%%
{hosts, ["publicname"] }.

Can anybody help me?
