Trigger script variables

You can use trigger script variables to pass data to a trigger script. All data is passed as a string. It is up to the trigger to interpret and use these data appropriately.

It is also possible to have the server and trigger communicate using STDIN and STDOUT. For more information, see Communication between a trigger and the server.

The maxError…​ variables refer to circumstances that prevented the server from completing a command, such as an operating system resource issue. Note also that client-side errors are not always visible to the server and might not be included in the maxError count.

The terminated and termReason variables indicate whether the command exited early and why.

Note

Any unknown variables remain in the trigger invocation. This preserves the trigger argument ordering, and might be a clue to authors that data they assumed to be available is not.

Argument Description Available for type

%action%

Either null or a string reflecting an action taken to a changelist or job.

For example,"pending change 123 added" or "submitted change 124 deleted" are possible %action% values on change forms, and "job000123 created" or "job000123 edited" are possible %action% values for job forms.

%changelist%, %change%

%serverAddress%

The IP address and port of the Helix Core Server, passable only in the context of a client-side script specified by P4LOGINSSO.

auth-check-sso (client-side script only)

%serverhost%

Hostname of the Helix Core Server.

all

%serverid%

The value of the Helix Core Server’s server.id. See p4 serverid in the Helix Core Command-Line (P4) Reference.

all

%serverip%

The IP address of the server.

all

%servername%

The value of the Helix Core Server’s P4NAME.

all
%serverpid% The thread ID that handles a command on Windows, and the PID on Linux/UNIX. all

%serverport%

The transport, IP address, and port of the Helix Core Server, in the format prefix:ip_address:port.

prefix can be one of ssl, tcp6, or ssl6. This means that the command p4 -p %serverport% can be used to connect to the server. It does not matter which of these types of connection the server uses.

Note

The %serverport% variable returns the P4PORT of the server where the trigger runs. For example:

changesubmit change-submit //... "bash change-submit.sh %serverport%"

shelvesubmit shelve-submit //... "bash shelve-submit.sh %serverport%"

Whether you are working through the commit server or an edge server, the change-submit trigger runs on the commit server. Therefore, the %serverport% variable for the change-submit trigger returns the P4PORT of the commit server.

However, a shelve trigger runs on the server where you shelve a changelist. If you shelve a changelist through an edge server, the shelve-submit trigger runs on that edge server. This is true whether the shelve is being promoted or not. Therefore, in this case, the %serverport% variable for the shelve-submit trigger returns the P4PORT of that edge server.

all
%serverprocesspid% The process identifier (PID) of the entire server process on both Windows and Linux/UNIX. all

%serverroot%

The P4ROOT directory of the Helix Core Server.

all

%serverservices%

A string specifying the role of the server. One of the following:

  • standard
  • replica
  • broker
  • proxy
  • commit-server
  • edge-server
  • forwarding-replica
  • build-server
  • P4AUTH
  • P4CHANGE

all except archive

all except archive
%sessionsPaused% Number of paused client commands.

form

%standbyserverid% Expands to the serverID of the standby before failover (or failback). failed-over, failed-back
%standbyserverport% Expands to the P4PORT of the standby before failover (or failback). failed-over, failed-back
%stream% The stream spec in the change, such as //streamDepot/streamProject1 change-submit
change-content
change-commit
change-failed

%submitserverid%

If this is not a distributed installation, %submitserverid% is always empty.

In a distributed installation, for any change trigger:

  • if the submit was run on the commit server, %submitserverid% equals %serverid%.
  • if the submit was run on the edge server, %submitserverid% does not equal %serverid%. In this case, %submitserverid% holds the edge server’s server id.

If there is a forwarding replica between the commit server and the edge server, then %submitserverid% actually holds the forwarding replica’s server id.

See p4 serverid in the Helix Core Command-Line (P4) Reference.
