p4-plugin keeps opening connection during the build. Causing long delays

    • Environment:
      Pipeline scripted
      p4 plugin v 1.9.2 (latest)
      Both on Jenkins 2.107.3 and 2.138.2.
      Also on clean installed Jenkins server

      After using the p4 plugin, and after it finished its task, the p4 plugin keeps opening connection and closing it. Each such action takes 1-2 seconds. So during the rest of the build, there is a delay of 5-20 seconds between the commands.

      How to reproduce:

      1. Go to <jenkins url>/log/ and add a new logger called "p4"
        Logger = "org.jenkinsci.plugins.p4" ; Log level = "ALL"
      2. Create a pipeline job with this script:
      node() {
          // library retriever: legacySCM(perforce( // fill your data here.
          // p4sync // fill your data here.
          stage('run') {
              3.times {
                  sh 'date'
      1. Build the Job
      2. Now remove one of the commented lines (library with perforce or p4sync), fill the needed data. You can use the "Pipeline Syntax".
      3. Build the Job again
      4. Compare the time that the 'run' stage took:
        1. in step 3 it took ~350 ms
        2. in step 5 it took 53 seconds
          and this time diff is only for 3 "sh" calls. For longer jobs it increases.
      5. Pay attention that this time is only for the 3 calls to "sh", and not including the p4 stage.
      6. Open the log you created at stage 1 (<jenkins url>/log/p4).
        You can see there a loop of
            P4: opened connection OK
            P4: closed connection OK
        Each "open" takes 1-2 seconds, and during this time the build can't proceed.
