Subject DO NOT REPLY [Bug 24110] New: - Starteam disconnect
Date Fri, 24 Oct 2003 17:59:42 GMT

Starteam disconnect

           Summary: Starteam disconnect
           Product: Ant
           Version: 1.5.4
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Optional Tasks

After using ANT to execute a build script with over 30 Starteam targets 
(stcheckout, stlabel) Starteam becomes very slow.  I believe this may be a case 
of not calling a actual server disconnect through the Starteam API.  See email 
discussion below for more details.

OK, thanks, Ross.  Please file a bugzilla report on this issue and I
promise I'll handle it.  Please append this email thread as an
attachment to the bug report.

I will put connection closing logic into each ant call.  Without looking
closely into it, I can see no reason not to as it's just basic
connection "hygiene".  I won't be able to test whether it solves your
problem, but you can be the arbiter of that.

Fair enough?

The Starteam server exists on a Windows 2000 box using  Microsoft Access
as the database, 1 Gig of memory, 2GHz processor.  Before you role your
eyes and tell me to start using a real database understand that at the
time it was all I could afford.  Furthermore, I have asked Borland
specifically whether my server configuration and the number of users I
support would put load on the server slowing it down, they responded
that everything should work with good performance.  Also, when I have
been experiencing slow performance I have gone to my server to see if
the processor is maxed out or it is short of memory, each time the
server has been fine.  As far as running the ANT scripts, I have been
using both Windows and Solaris with various graphical front ends
(Antelope, and through Eclipse).  When I started having these problems I
have switched to ANT command line in hopes it was a problem with one of
the GUI tools.  Even ANT command line produces this problem.

The exact actions that cause this problem are as follows.  Assume I have
just rebooted the server and there are no connections to it.  I start my
build script from Solaris using ANT command line.  The build script uses
approx 30 Starteam ANT task calls (stcheckout stlabel only).  As the
build script executes, all the Starteam tasks are fast, the 30th call is
as fast as the first.  The build script finishes.  After the build
finishes if I try and use the Starteam GUI to check out code it is
extremely slow.  If I were to run another build script all the Starteam
ANT tasks (stcheckout, stlabel) are extremely slow.  I wait some amount
of time (I do not know the exact time but it is around 15 minutes) and
everyhing is back to normal, Starteam GUI is fast again, if I run
another build it will be fast again.  When I first started my build
script it was small, around 5 calls to Starteam ANT tasks, I never had
these problems when there was a small amount of Starteam targets in the
script.  If I run a script that has 5 Starteam targets the server does
NOT slow down after.  I have run netstat on the Starteam server when the
build is running and there seems to be a new connection to the build
client for every Starteam target called.  These connections are visible
through netstat until the build ends, when the build is over the
connections are no longer visible using netstat.  Finally, if I restart
the Starteam server when it is in a slow state when it comes back up
everything is fine.

Thanks for the help.

Hmm, I have never noticed this.  While what you say certainly sounds
logical (clean up after yourself, basically, as you must do with
database connections, etc.) I have never experienced it myself.  I can
certainly take a look at putting connection-closing logic into these
tasks, especially as the connection is not reused between task

What client and server environments are you doing this in?

I am using ANT with Starteam and having some troubles.  Right now my
build script makes around 30 separate calls to Starteam targets
(stcheckout, stlabel exclusively).  When the build is finished Starteam
seems to get into a weird state where everything is extremely slow (i.e.
using the Starteam gui to checkin or checkout code is really slow).  The
slowness eventually goes away, some sort of timeout I am guessing.  I
tried to help myself and started poking around the ANT source code to
see how the Starteam API is used.  I think I found the call to the
Starteam API that connects to the server, it is:

In class

The function is:

     * All subclasses will call on this method to open the view needed
     * processing.  This method also saves a reference to the
     * <code>Server</code> that may be accessed for information at
     * points in the process.
     * @return the <code>View</code> that will be used for processing.
     * @see #createSnapshotView(View)
     * @see #getServer()
    protected View openView() throws BuildException {

        View view = null;
        try {
            view = StarTeamFinder.openView(getViewURL());
        } catch (Exception e) {
            throw new BuildException(
                "Failed to connect to " + getURL(), e);

        if (null == view) {
            throw new BuildException("Cannot find view" + getURL() +
                    " in repository()");

        View snapshot = createSnapshotView(view);
        this.server = snapshot.getServer();
        return snapshot;

You can see from the comments that this code returns a Starteam view
(and keeps a connection to the server) to the caller.  My question is,
does this connection have to be closed after you are finished using
it????  I have found no code in the ANT source that actually disconnects
( if there is some please point me to it).  I have been in contact with
the Borland support who claim there is disconnect method that can be
called to disconnect from the server (I am not sure it applies in this
case).  I have requested the Starteam API docs from Borland but they
seem to be ignoring me.  Hoping someone here would know.
