StatSVN on remote system throwing GTK Display issue

Reply Threaded

I am trying to set up StatSVN towards the end that it will be a cron job run every night.
However, statSVN dies with a GTK issue. I do not see an option to manage this in the help anywhere.
How do I deal with this?

Detailed situation:
I am SSH'd into a remote system; headless I believe.
(uname: Linux SERVERNAME-REMOVED 2.6.18-92.1.13.el5 #1 SMP Thu Sep 4 03:51:01 EDT 2008 i686 i686 i386 GNU/Linux)

I have my local SVN repository set up and checking out correctly.
I create a log:

svn -v --xml > svn.log

I run:

java -jar statsvn.jar -output-dir ~/public_html/svnstats/statsvn ~/temp/masters-svn/svn.log ~/temp/masters-svn

I get back:
(.:27686): Gtk-WARNING **: cannot open display:
And a set of files in my specified directory:

Good evening,

- You're not the first to complain about problems in a headless environment.

- I think StatCVS/StatSVN are supposed to work in a headless environment and
we have some AWT settings so that JFreeChart does work in a headless
environment.
- We probably are doing something wrong in the code to cause this error.
- It merits investigation.

Would you volunteer to file the issue in our issue tracker and track the
issue down?

Thanks,

Hi,

I'll try to get it hooked into the Sourceforge bugtracker.

However, my java knowledge is finite and I may not be able to actually fix it.

I'll do what I can though.

Pinpointing where/when the exception is thrown would be a great start. Usually, with a debugger, it would be easy, but since you’re running on a headless machine, it could be tricky.

You can find all references in Eclipse pretty quickly but basically I’m guessing none of the files in StatSVN will make direct references to it and all the references are in StatCVS (which StatSVN extends).

In StatSVN, the Main.java file includes this code:

// make JFreeChart work on systems without GUI

System.setProperty("java.awt.headless", "true");

In StatCVS, the following directories are good places to look.

/src/net/sf/statcvs/charts/*

and

/src/net/sf/statcvs/output/*

By the way, try setting that system property (java.awt.headless) in your command line session to see if it makes a difference.

Thanks,

Jason

Correct, StatCVS fails with the same issue.

I've tried a System.out.println(/*filename/line */); dump before each creation of a chart object. It dies sometime after line 108 in the the LOCChartmaker file is passed and before any other calls to my printfs.

StatCVS also sets java.awt.headless to true. From what I can tell, that's *supposed* to be a global property. I also don't see it being reset anywhere.

I'll keep you posted.

Isolating the function down to LOCChartMaker. I forced a stack dump exception and got this trace:

at net.sf.statcvs.charts.LOCChartMaker.createLOCChart(LOCChartMaker.java:111)

at net.sf.statcvs.charts.LOCChartMaker.<init>(LOCChartMaker.java:99)

at net.sf.statcvs.Main.generateDefaultHTMLSuite(Main.java:211)

at net.sf.statcvs.Main.main(Main.java:76)

It appears that this line causes the fault:

final JFreeChart chart = ChartFactory.createTimeSeriesChart(this.config.getProjectName() + ": " + title, domain, range, data, legend, false, false);

in LOCChartMaker.java

Setting the property to headless immediately prior to that call does not change the crash.

Hope this helps.

From what I can see, we’re doing everything we can in StatSVN/CVS. It appears that either:

- Your default AWT toolkit isn’t behaving properly.

- There’s something different on your OS.

Here are some references:

http://java.sun.com/products/java-media/2D/reference/faqs/index.html#xvfb

http://www.jfree.org/phpBB2/viewtopic.php?t=1012

There are a few workarounds listed at the URLs above. (virtual X servers,trying another AWT toolkit). Can you try one and if it works, let us know and we’ll create an entry in the StatSVN wiki?

Thanks for doing this research!

System.setProperty("java.awt.headless", "true");

In StatCVS, the following directories are good places to look.

/src/net/sf/statcvs/charts/*

and

/src/net/sf/statcvs/output/*

By the way, try setting that system property (java.awt.headless) in your command line session to see if it makes a difference.

Thanks,

Well, I'm glad to see that Stat* is working correctly. My bet is it's something mis/unconfigured with the system I was using. I'm using Java 1.4.2, as best as I can tell.

Thanks for your assistance.

There are a few workarounds listed at the URLs above. (virtual X servers,trying another AWT toolkit). Can you try one and if it works, let us know and we’ll create an entry in the StatSVN wiki?

Thanks for doing this research!

Isolating the function down to LOCChartMaker. I forced a stack dump exception and got this trace:

   at net.sf.statcvs.charts.LOCChartMaker.createLOCChart(LOCChartMaker.java:111)

   at net.sf.statcvs.Main.generateDefaultHTMLSuite(Main.java:211)
   at net.sf.statcvs.Main.main(Main.java:76)

It appears that this line causes the fault:
   final JFreeChart chart = ChartFactory.createTimeSeriesChart(this.config.getProjectName() + ": " + title, domain, range, data, legend, false, false);
in LOCChartMaker.java
Setting the property to headless immediately prior to that call does not change the crash.

Hope this helps.

You can find all references in Eclipse pretty quickly but basically I’m guessing none of the files in StatSVN will make direct references to it and all the references are in StatCVS (which StatSVN extends).

In StatSVN, the Main.java file includes this code:

    System.setProperty("java.awt.headless", "true");

Hi Jason,

(A year later, due to obscure laziness and a workaround involving a headed server)

I grubbed around and traced the immediate problem back to the graph generation library. I suppose one solution here is to tear out the graph generation library and replace it with X-independent code.

However, I did some rummaging around and it seems to be a problem either in Java or my server's installation. This demo article here fails with the identical error.

http://www.j2ee.me/developer/technicalArticles/J2SE/Desktop/headless/

I'm in contact with my sysadmin now to see if he's willing to work with me here, but I'm not optimistic that he'll devote a large slice of his time for one user out of several hundred. ;-)

If someone with root could reproduce the GTK error on the above code, I think we might be able to move forward on this.

Thanks,
Paul

What you claim here sounds consistent with what I've heard.

We use the same headless parameters as in that article and, to my knowledge, most people don't have any issues with it. However, you're not the only one who has encountered this kind of issue. It seems entirely plausible that some versions of certain libraries on certain setups don't work properly. In the past year, I think we've updated the JFreeChart library that Stat(CVS/SVN) use - have you tried out the most recent versions?

Thanks,

Re: [Statsvn-users] StatSVN on remote system throwing GTK Display issue

Yes; same issue.

My Java info:
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-46).

My StatSVN info is version 0.5.

I strongly suspect the error something to do with the Java AWT libs installed for a particular configuration.

After some rummaging, I found a possible solution is to load Xvfb and engage StatSVN.

Xvfb :1 &

DISPLAY:=1 java (command line)

Still setting the headless values, needs some iteration to determine if this negates the need for headlessness period or if Xvfb + headless is required.

This worked correctly, from what I could tell. I'd appreciate it if someone else could repro the fix on their systems. I'll be investigating this over the next few days as well, but I don't have Root.

Thanks,

Paul
