[JIRA] [matrix-combinations-parameter] (JENKINS-24790) Matrix plugin - Label expression pick invalid node

[satpal.chan...@bromium.com (JIRA)]

Satpal Chander created JENKINS-24790 Matrix plugin - Label _expression_ pick invalid node Issue Type: Bug Assignee: Unassigned Components: matrix-combinations-parameter Created: 22/Sep/14 7:01 AM Description: I'm seeing strange behaviour when i'm using a matrix job with the label expressions. I have the following setup: 4 nodes with the following labels: testnode0 - 4gb maintestpool testnode1 - 4gb maintestpool testnode3 - 8gb maintestpool testnode4 - 8gb maintestpool All nodes have only 1 executor. In the matrix job (build concurrent enabled) I have specified the label _expression_ as: Name - node Label Expressions: !under_test&&4gb&&maintestpool !under_test&&8gb&&maintestpool My understanding of this _expression_ is - pick the next two nodes that, don't have the under_test label and one has label 4gb and one has label 8gb and both have the label maintestpool I then append the label 'under_test' to each of the chosen nodes - This is because I reboot the nodes as part of a downstream multijob test run and hopefully this will stop a pending job pinching the node mid way through a test run. The downstream multijob is triggered with a string parameter $NODE_NAME (Jenkins env var) because everything in the build section and beyond of the matrix jobs is run on the node chosen by the Label _expression_, each of the multijobs sub jobs are passed the $NODE_NAME parameter as a Label param. Now the problem is that if I kick off 3 matrix jobs the last job should just queue unit the down stream job has finished (which then remove the under_test label) However what is happening is that the all 3 job are pushed onto the first two nodes matching the _expression_ Job 1 on - !under_test&&4gb&&maintestpool - has the following output: 23:33:15 Building remotely on testnode0(4gb maintestpool) in workspace /Users/builduk/Jenkins/Home/DSL_osx_tests_martix/node/!under_test&&4gb&&maintestpool 23:33:15 [!under_test&&4gb&&maintestpool] $ /bin/sh -xe /var/folders/88/kjb_0d_x7sx525zv6bz2c4w80000gn/T/hudson619443788463271298.sh 23:33:15 + echo '!under_test&&4gb&&maintestpool' 23:33:15 !under_test&&4gb&&maintestpool 23:33:15 Adding under_test label 23:33:15 hudson.slaves.DumbSlave@7ecde659 23:33:15 Test node is: testnode0 23:33:15 Original Labels: 10.9.4 4gb maintestpool 23:33:15 Adding under test label 23:33:15 Setting labels: 10.9.4 4gb maintestpool under_test Which is fine, exactly what i want. Then the job is kicked off again: 23:33:19 Building remotely on testnode0 (4gb under_test maintestpool) in workspace /Users/builduk/Jenkins/Home/DSL_osx_tests_martix/node/!under_test&&4gb&&maintestpool 23:33:19 [!under_test&&4gb&&maintestpool] $ /bin/sh -xe /var/folders/88/kjb_0d_x7sx525zv6bz2c4w80000gn/T/hudson2089316416162620658.sh 23:33:19 + echo '!under_test&&4gb&&maintestpool' 23:33:19 !under_test&&4gb&&maintestpool 23:33:19 Adding under_test label 23:33:19 hudson.slaves.DumbSlave@7ecde659 23:33:19 Test node is: norfolk 23:33:19 Original Labels: 10.9.4 4gb verificationpool office i5 ssd maintestpool under_test 23:33:19 Script returned: 1 Which is not what I want, as you can see from the first line the 'under_test' label exists therefore the matrix job should not have chosen this node, it should have moved onto testnode1. You can see script return 1 - this because my script that appends the label 'under_test', checks if it is already present in the label list, which is clearly is. The same happens for the third job Does anyone know what I'm doing wrong. Thanks - Apologies for the length of the post satpal Environment: Jenkins 1.554.3 Mtrix plugin 1.3 Project: Jenkins Priority: Critical Reporter: Satpal Chander
