issues with svc - 2002-07-18 [message #9972]

Hello,

I have succesfully checked-out stellation and installed it
as a server. I have encountered some problems in setting up
an environment.

Here is a session transcript:
florin@bee:~/work/projects$ mkdir new-browser
florin@bee:~/work/projects$ svc create new-browser/

org.eclipse.stellation.repos.util.StellationException: unable to
locate artifact for ID -1

1. It appears that when you give a directory with a trailing /,
stellation succesfully removes it but it unable to do anything
with the resulting directory.

2. Adding the same directory twice confuses stellation. At least it
is consistent in its confusion.

3. Now I'm stuck. What am I supposed to do to get those files in?

4. I checkin the project hoping it will allow me to add files to
the subdirectory... No success.

Another very bad thing is that the four threads of the stellation
"server" are eating 100% of the CPU time on a PIII/700 .

Thank you,
florin

Not quite... It's doing just fine with the trailing "/" - although
I recommend not putting the "/" into the project name. (Stellation
isn't like CVS: the name of the project is not the name of the
directory.)

The problem is that the svc command-line tool doesn't know how to
find the workspace metadata. All of the commands will work from
the directory containing the "SVC" metadata directory - so, for
example, doing "svc add dtds/*.dtd" from the "new-browser" directory
would work.

As an alternative, running "svc --within add *.dtd" from the dtds
directory would work: "--within" tells the SVC command-line that
the current directory is in a workspace, and to search upwards
through the directories for the metadata directory.

That looks like a bug. Would you mind reporting it in bugzilla? (If
it's a problem, I'll add it, but it's useful to us to have the users
that find a bug be the ones to report it, when possible.)

> 3. Now I'm stuck. What am I supposed to do to get those files in?

See above. Either run the command from the root directory of the
workspace, or use "--within".

I haven't seen that on our server, except when the server is actively
processing a checkin. The diff computation that goes on during a checkin
really is a CPU intensive thing. Are you seeing that CPU usage even when
the server is idle? (I'm running a server on my machine right now,
and I'm seeing *no* CPU usage when there's no client talking to it. It
spikes pretty high during a checkin, but during idle, it doesn't
even show up in "top".)

I'd like to try to figure out what's going on that's causing it to do
that, so that we can fix it. Can you give me any more data? (i.e., what
JVM? what version of linux? Anything else you can think of that might
help me reproduce it would help.)

As soon as I pressed "Send" I realized I should have given you more
info about it.

Here it is:
OS: Debian GNU/Linux "woody"
Kernel: linux-2.4.19-rc2-ac2
Java:
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
Postgresql: 7.2.1-3
JDBC driver: 7.2-1

I am downloading IBM JDK 1.3.1 right now and I will try again with it.

I dont't think so: look again at the transcript. The "unexpected null"
error message doesn't appear after "svc add dtds/; svc add dtds",
it only appears after "svc add dtds; svc add dtds", which leads me
to believe that the first time it didn't create the entry.

Shouldn't that be the default case? I mean, most of the time when
I try a checkin/out/whatever I am in a repository - or at least I
*think* I am. If not, I expect an error message.

Optimize for the most frequent case.

I can confirm that IBM JDK
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1)
Classic VM (build 1.3.1, J2RE 1.3.1 IBM build cxia32131-20020410 (JIT
enabled: jitc))

doesn't exhibit the same problem.

Thank you! That should be a huge help. I doubt I'll have time today, but
over the weekend, I'll try to download the Sun JDK, and see if I can
reproduce it, and figure out what's wrong.

I'll take a look at it when I get in to my office. If I can reproduce it,
it should be a pretty trivial thing to fix.

This was actually a point of debate in the group. I wanted it automatic;
others disagreed. In the end, our decision was to leave it an option, but
one which could be put into your configuration file to make it appear
as if it was a real default.

Look at the section of the tutorial about "configure within" to see
how to make it the default.

Thanks. We'll try to fix it ASAP.
