jMeter development project inquiry
Dear jMeter list, (-user list included due to amount of commit msgs on -dev, followup set to -dev) We are using jMeter to perform conformance and regression tests periodically (typically every 15 minutes, for a large number of tests), and are looking for ways to push integration a bit further. We are investigating whether it is possible to develop the option described below: --- The ability to POST a .jmx file to a running jMeter server over an HTTP connection using a REST (or SOAP) interface and return the results, either directly (in the same connection) or via a call-back URL. This would be the equivalent of using -t and -l options on the command-line with the benefit that the server runs continuously and the client-side calls for executing a script become very cheap (i.e. no Java startup time). The API should be documented and specs made available to the community. --- We would like to know if this is in fact feasible (or even sensible) project. And if so, we are hoping to be able to sponsor a large part of the development costs for any jMeter developer who likes to develop this. The goal of this project is to have this included in vanilla jMeter in a way such that the jMeter community is able to support and maintain the code (with us) after the initial development. Therefore, naturally, the implementation would be licensed under the same license as jMeter. Please let us know your opinion.

ANY REPLY MADE TO THIS MESSAGE WILL NOT BE COLLECTED AND· INSERTED IN THE BUG DATABASE. http://issues.apache.org/bugzilla/show_bug.cgi?id=44126 Summary: ConcurrentModificationException executing test on multiple machines Product: JMeter Version: 2.3.1 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: Main AssignedTo: jmeter-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I have a single, simple test with one thread group (2 threads, ramp up time 1, loop 1). The thread group contains 3 HTTP requests (1 POST that sends contents of a small file and 2 GETs) and one View Results Tree listener. In jmeter.properties: mode=Batch, num_sample_threshold=1000, and time_threshold=6. Only other modifications to jmeter.properties: jmeter.laf=javax.com.sun.java.swing.plaf.windows.WindowsLookAndFeel and 6 remote_hosts defined. From the master GUI, I call Run-Remote Start All and I get: Exception in thread Thread-4 java.util.ConcurrentModificationException at java.util.LinkedHashMap$LinkedHashIterator.nextEntry(LinkedHashMap.java:365) at java.util.LinkedHashMap$ValueIterator.next(LinkedHashMap.java:380) at org.apache.jmeter.testelement.property.PropertyIteratorImpl.next(PropertyIteratorImpl.java:50) at org.apache.jmeter.engine.util.ValueReplacer.replaceValues(ValueReplacer.java:113) at org.apache.jmeter.engine.util.ValueReplacer.replaceValues(ValueReplacer.java:65) at org.apache.jmeter.engine.PreCompiler.addNode(PreCompiler.java:70) at org.apache.jorphan.collections.HashTree.traverseInto(HashTree.java:972) at org.apache.jorphan.collections.HashTree.traverseInto(HashTree.java:973) at org.apache.jorphan.collections.HashTree.traverse(HashTree.java:956) at org.apache.jmeter.engine.ClientJMeterEngine.run(ClientJMeterEngine.java:116) at java.lang.Thread.run(Thread.java:595) The error also occurs with mode=Statistical and with the Summary Report listener. I didn't see this error as often with fewer remote hosts. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The error doesn't occur every time, but if it occurs, one of the remote slaves doesn't run the test. All jmeter properties I modified except remote_hosts seem to be irrelevant: the greater the number of remote_hosts, the more likely it is that this ConcurrentModificationException will occur. (I'm now testing with 7 remote hosts.) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
