Hello, (on JMeter 2.5.1RC1) Don't retry automatically with HC4 sampler seems introduce a bug on load tests using HC4.
When you run a load test, some errors "The target server failed to respond" can appear on response data. With wireshark, this error arrives at the end of TCP conversations: the GET request is sent, but no server response (the connection has been closed, I suppose). If I changes the property httpclient4.retrycount to 3, the load tests works fine, with no errors. This bug is tested on Linux with JVM5/7 and WinXP with JVM7 Test case is the Simple Test Case on this bugs: https://issues.apache.org/bugzilla/show_bug.cgi?id=51863 (Note: no errors with HC3.1) (Questions: retrycount exists on HC3.1? if yes what default value?) ====Response data==== org.apache.http.NoHttpResponseException: The target server failed to respond at org.apache.http.impl.conn.DefaultResponseParser.parseHead(DefaultResponseParser.java:101) at org.apache.http.impl.io.AbstractMessageParser.parse(AbstractMessageParser.java:252) at org.apache.http.impl.AbstractHttpClientConnection.receiveResponseHeader(AbstractHttpClientConnection.java:281) at org.apache.http.impl.conn.DefaultClientConnection.receiveResponseHeader(DefaultClientConnection.java:247) at org.apache.http.impl.conn.AbstractClientConnAdapter.receiveResponseHeader(AbstractClientConnAdapter.java:219) at org.apache.http.protocol.HttpRequestExecutor.doReceiveResponse(HttpRequestExecutor.java:298) at org.apache.http.protocol.HttpRequestExecutor.execute(HttpRequestExecutor.java:125) at org.apache.http.impl.client.DefaultRequestDirector.tryExecute(DefaultRequestDirector.java:645) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:464) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:754) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sample(HTTPHC4Impl.java:265) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:62) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1010) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:996) at org.apache.jmeter.threads.JMeterThread.process_sampler(JMeterThread.java:383) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:276) at java.lang.Thread.run(Thread.java:595) ===================== Milamber Le 01/09/2011 17:52, s...@apache.org a ecrit : > Author: sebb > Date: Thu Sep 1 17:52:41 2011 > New Revision: 1164186 > > URL: http://svn.apache.org/viewvc?rev=1164186&view=rev > Log: > Don't automatically retry with HttpCLient4 sampler > > Modified: > jakarta/jmeter/trunk/bin/jmeter.properties > > jakarta/jmeter/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java > jakarta/jmeter/trunk/xdocs/changes.xml > jakarta/jmeter/trunk/xdocs/usermanual/component_reference.xml > > Modified: jakarta/jmeter/trunk/bin/jmeter.properties > URL: > http://svn.apache.org/viewvc/jakarta/jmeter/trunk/bin/jmeter.properties?rev=1164186&r1=1164185&r2=1164186&view=diff > ============================================================================== > --- jakarta/jmeter/trunk/bin/jmeter.properties (original) > +++ jakarta/jmeter/trunk/bin/jmeter.properties Thu Sep 1 17:52:41 2011 > @@ -251,7 +251,7 @@ log_level.jorphan=INFO > # 0 now means don't retry connection (in 2.3 and before it meant no tries at > all!) > > #--------------------------------------------------------------------------- > -# HTTPClient configuration > +# Commons HTTPClient configuration > #--------------------------------------------------------------------------- > > # define a properties file for overriding Commons HttpClient parameters > @@ -302,7 +302,7 @@ log_level.jorphan=INFO > #log_file.httpclient=httpclient.log > > > -# Apache HttpClient logging examples > +# Apache Commons HttpClient logging examples > # > # Enable header wire + context logging - Best for Debugging > #log_level.org.apache.http=DEBUG > @@ -320,6 +320,13 @@ log_level.jorphan=INFO > #log_level.org.apache.http.client=DEBUG > > #--------------------------------------------------------------------------- > +# Apache HttpComponents HTTPClient configuration (HTTPClient4) > +#--------------------------------------------------------------------------- > + > +# Number of retries to attempt (default 0) > +#httpclient4.retrycount=0 > + > +#--------------------------------------------------------------------------- > # Results file configuration > #--------------------------------------------------------------------------- > > > Modified: > jakarta/jmeter/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java > URL: > http://svn.apache.org/viewvc/jakarta/jmeter/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java?rev=1164186&r1=1164185&r2=1164186&view=diff > ============================================================================== > --- > jakarta/jmeter/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java > (original) > +++ > jakarta/jmeter/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java > Thu Sep 1 17:52:41 2011 > @@ -50,6 +50,7 @@ import org.apache.http.auth.NTCredential > import org.apache.http.auth.UsernamePasswordCredentials;
