dirkraft / JavaPIDishTest.sh

Last active October 13, 2015 02:58

Java PID equivalent test, since there's really no guarantee in any direction (exception, format, ...) what this might do. Used this on an ec2 instance to make sure some metrics code wouldn't explode with OpenJDK.

	echo "Does my jvm output something reasonable for a PID equivalent?"
	echo "public class Main{public static void main(String[]args){System.out.println(java.lang.management.ManagementFactory.getRuntimeMXBean().getName());}}" > Main.java
	javac Main.java
	java Main

divergent performance between alternating conditional and random conditional

	import java.util.ArrayList;
	import java.util.Collections;
	import java.util.List;
	import java.util.Random;

	/**
	* sort_strat<ul>
	* <li>0 random numbers - slowest by a factor of 5 than strat 2 or 3</li>
	* <li>1 random numbers sort time included - by far the slowest, even NOT counting the sort time. This one is puzzling.</li>
	* <li>2 incrementing numbers - same as 2</li>

Performs `gradle dependencyInsight` recursively over all modules. `gxargs` because brew install gnutls on a mac. built-in xargs is a POS. Gradle 1.11 dependencyInsight is significantly more reliable than 1.10. Go 1.11

	SAMPLE_DEPENDENCY="jersey-core"

	find . -type f -name build.gradle -exec dirname {} \; \
	\| gxargs -I{} gradle -p {} dependencyInsight --dependency ${SAMPLE_DEPENDENCY}
