Nailgun / IRB hang under launchd
--------------------------------
Key: JRUBY-4753
URL: http://jira.codehaus.org/browse/JRUBY-4753
Project: JRuby
Issue Type: Bug
Components: Launcher
Affects Versions: JRuby 1.5
Environment: JVM 1.5 on Leopard PPC
Reporter: Ian Dees
Assignee: Thomas E Enebo
{{jruby --ng -S irb --noreadline}} hangs when attempting to connect to an
instance of Nailgun that was started with {{launchctl}}. Other uses of {{jruby
--ng}} seem to work, such as checking the version or running a script. Also,
the setup works when Nailgun is started from the command line, rather than a
launchd script.
Here is the affected launchd script:
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.example.nailgun</string>
<key>ProgramArguments</key>
<array>
<string>/bin/sh</string>
<string>-c</string>
<string>/Users/username/bin/nailgun-server</string>
</array>
</dict>
</plist>
{noformat}
... and here are the contents of the {{nailgun-server}} it calls:
{noformat}
#!/bin/sh
export PATH=$PATH:/usr/local/bin
/Users/username/src/ext/jruby/bin/jruby --ng-server 127.0.0.1:55555
{noformat}
Nailgun + launchd + IRB worked fine together in revisions before f4f572.
