Subject [jira] [Commented] (COUCHDB-1669) Unable to start CouchDB in background through a psuedo-tty
Date Mon, 21 Apr 2014 05:15:16 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975399#comment-13975399
] 

Joan Touzet commented on COUCHDB-1669:
--------------------------------------

Confirmed on Debian 7.4. This is a result of how couchdb -b recurses and creates a grandchild
process. Sadly this isn't a quick fix, will keep looking.

> CouchDB crashes when started as a background process in a psuedo-tty.
> Steps to reproduce:
> On a machine that you can ssh into localhost do:
> ssh -tt localhost "/path/to/couchdb -b"
> When the connection closes, CouchDB will be killed.
> A few things I've discovered while debugging
> When I do
> ssh -tt localhost "~/build-couchdb/build/bin/couchdb -b && sleep 10 &&
curl localhost:5984"
> The output from the command is:
> Apache CouchDB has started, time to relax.
> {"couchdb":"Welcome","version":"1.2.1"}
> Connection to localhost closed.
> The contents or couchdb's stdout file is 
> Apache CouchDB 1.2.1 (LogLevel=info) is starting.
> Apache CouchDB has started. Time to relax.
> [info] [<0.32.0>] Apache CouchDB has started on http://127.0.0.1:5984/
> [info] [<0.131.0>] 127.0.0.1 - - GET / 200
> The contents of couchdb's stderr is
> heart_beat_kill_pid = 32631
> heart_beat_timeout = 11
> heart: Mon Feb  4 07:31:57 2013: Erlang has closed.
> heart: Mon Feb  4 07:31:58 2013: Executed "/home/ubuntu/build-couchdb/build/bin/couchdb
-k" -> 0. Terminating.
> This happens no matter how I start CouchDB: as a service, with the init script, with
nohup, or with the command above. I built CouchDB using the build instructions for Ubuntu
12.04 from the wiki and using the build-couchdb project on Github.
> The really odd thing is that this only happens when I start couchdb with `ssh -tt`. If
I ssh into localhost and start couchdb in the background, it will continue running after I
exit the ssh session.
