It generates a login ticket for the SDP super user, defined by P4USER when sourcing the SDP standard shell environment. It is called from cron scripts, and so does not normally generate any output. If run on a replica with the -service option, the serviceUser defined for the given replica is logged in. The \$SDP_AUTOMATION_USERS variable can be defined in $P4CCFG/p4_N.vars. If defined, this should contain a comma-delimited list of automation users to be logged in when the -automation option is used. A definition might look like: export SDP_AUTOMATION_USERS=builder,trigger-admin,p4review Login behaviour is affected by external factors: 1. P4AUTH, if defined, affects login behavior on replicas. 2. The auth.id setting, if defined, affects login behaviors (and generally simplifies them). 3. The \$SDP_ALWAYS_LOGIN variable. If set to 1, this causes p4login to always execute a 'p4 login' command to generate a login ticket, even if a 'p4 login -s' test indicates none is needed. By default, the login is skipped if a 'p4 login -s' test indicates a long-term ticket is available that expires 31+days in the future. Add \"export SDP_ALWYAYS_LOGIN=1\" to $P4CCFG/p4_N.vars to change the default for an instance, or to $P4CBIN/p4_vars to change it globally. If unset, the default is 0. OPTIONS: <instance> Specify the SDP instances. If not specified, the SDP_INSTANCE environment variable is used instead. If the instance is not defined by a parameter and SDP_INSTANCE is not defined, p4login exists immediately with an error message. -service Specify -service when run on a replica or edge server to login the super user and the replication service user. This option is not compatible with '-p <port>'. -p <port> Specify a P4PORT value to login to, overriding the default defined by P4PORT setting in the environment. If operating on a host other than the master, and auth.id is set, this flag is ignored; the P4TARGET for the replica is used instead. This option is not compatible with '-service'. -automation Specify -automation to login external automation users defined by the \$SDP_AUTOMATION_USERS variable. -v Show ouptput of login attempts, which is suppressed by default. Setting SDP_SHOW_LOG=1 in the shell environment has the same effect as -v. -L <log> Specify the log file to use. The default is /p4/N/logs/p4login.log -d Set debugging verbosity. -D Set extreme debugging verbosity. HELP OPTIONS: -h Display short help message -man Display man-style help message EXAMPLES: 1. Typical usage for automation, with instance SDP_INSTANCE defined in the environment by sourcing p4_vars, and logging in only the super user P4USER to P4PORT: source $P4CBIN/p4_vars abc p4login Login in only P4USER to the specified port, P4MASTERPORT in this example: p4login -p \$P4MASTERPORT Login the super user P4USER, and then login the replication serviceUser for the current ServerID: p4login -service Login external automation users (see SDP_AUTOMATION_USERS above): p4login -automation Login all users: p4login -all Or: p4login -service -automation LOGGING: This script generates no output by default. All (stdout and stderr) is logged to /p4/N/logs/p4login.log. The exception is usage errors, which result an error being sent to stderr followed usage info on stdout, followed by an immediate exit. If the '-v' flag is used, the contents of the log are displayed to stdout at the end of processing. EXIT CODES: An exit code of 0 indicates a valid login ticket exists, while a non-zero exit code indicates a failure to login.
