use of org.neo4j.server.startup.ProcessManager.behaviour in project neo4j by neo4j.

the class WindowsBootloaderOs method runProcess.

        // This is special condition where we run a command with our prunsrv windows-service util and we have to run it with powershell,
        // probably because we're running a command which exceeds 2000 characters which is the limit of cmd.exe.
        // Since it seems to be really hard to make powershell wait for completion of commands that it runs (we've certainly tried)
        // then we have to try and wait the completion manually here. The general idea is to see if there's any prunsrv process running
        // and we're simply waiting until there is none. Now this is somewhat risky because if there's any other process with the exact same name
        // we'll wait here for the max time. Although know that the PS1 scripts that this was ported from doesn't even have the option to run
        // these prunsrv commands in powershell.exe, it always ran them in cmd.exe. The main cause of a command line being too long for cmd.exe
        // is that the classpath is too long since other things are somewhat fixed and doesn't exceed this limit on any sane environment.
        // And the main reason the classpath is too long is that we're currently running in a test environment, because in a real-world
        // packaging environment the classpath is a couple of wildcard directories.
