[jira] Created: (IVY-1075) Publish with SSH (sftp or ssh) prevents
enclosing java process to terminate
Publish with SSH (sftp or ssh) prevents enclosing java process to terminate
---------------------------------------------------------------------------
Key: IVY-1075
URL: https://issues.apache.org/jira/browse/IVY-1075
Project: Ivy
Issue Type: Bug
Affects Versions: 2.1.0-RC1
Environment: buildr 1.3.4 running on jruby 1.2.0 with latest jsch-0.1.41 jar
Reporter: Klaas Prause
We try to add ivy support to buildr. Buildr comes with an AntWrap gem to call Ant targets from within a buildr script:
1. using a standard publish via Antwrap using the same parameters that work in Ant
2. the publish works all artifacts are copied and the buildr script continues till its end, but the buildr java process does not terminate!
when publishing to a local repository the process terminates fine, so it has something to do with the SSH connection.
using lsof and checking the open file handles the process has an open connection to the repository via SSH and some other open sockets (lsof output for process):
[...]
java 23589 klaas 31u IPv6 342503 TCP brackel.local:43473->argon:ssh (ESTABLISHED)
java 23589 klaas 32u sock 0,4 342501 can't identify protocol
java 23589 klaas 11u unix 0xf5744a80 342386 socket
[...]
I checked out the source but could not find the problem. My best guess is that the last SSH connection is cached within SshCache and never disconnected from Ivy.
This is a blocker to change from ANT to Buildr, because the build scripts do not terminate normally so they cannot be used in the integration server.
We have the same problem with an hanging jruby script using Ivy not via Ant but via the Ivy class to resolve projects. The Ivy class is instantiated from within JRuby and used to resolve ivy.xmls to get some information about projects. The script does not terminate after a resolve against a remote repository using SSH has been done.

Klaas Prause commented on IVY-1075:
-----------------------------------
>From the thread dump the operation blocks in JSch library. The Session class has one thread for the connection and blocks inside the run method trying to read bytes from the server. The read method is documented as blocking till bytes can be read, end of file is encountered or an exception is thrown.
I cannot say if the Session from jsch is the problem or the way ivy uses the library. I do not understand the difference between normal use via Ant and the use via Buildr an Antwrap.

------------------------------------------------------------
this issue describes the problem:
http://svnkit.com/tracker/view.php?id=52
when I am end the buildr process explicitly with "System.exit(0)" the open SSH connections are closed and the process returns.
Maybe Ivy should provide an option to terminate the open SSH connections in the pool as implemented in SVNKit (SVNJschSession.shutdown()).

[jira] Resolved: (IVY-1075) Publish with SSH (sftp or ssh) prevents

Maarten Coene resolved IVY-1075.
--------------------------------
Resolution: Fixed
Fix Version/s: trunk
I think I was able to solve this problem without adding an extra Ant task to close the sessions.
Could you give it a try (I cannot test it to see if it really works) and provide us your feedback?
thanks,
Maarten

> We try to add ivy support to buildr. Buildr comes with an AntWrap gem to call Ant targets from within a buildr script:
> 1. using a standard publish via Antwrap using the same parameters that work in Ant
> 2. the publish works all artifacts are copied and the buildr script continues till its end, but the buildr java process does not terminate!
> when publishing to a local repository the process terminates fine, so it has something to do with the SSH connection.
