p4 groups

p4 group

Synopsis

Add or delete users from a group, or set the maxresults, maxscanrows, maxlocktime, and timeout limits for the members of a group.

Syntax

p4 [g-opts] group [ -a ] groupname
p4 [g-opts] group -d [ -a ] groupname
p4 [g-opts] group -o groupname
p4 [g-opts] group -i [ -a ]

Description

A group is a list of Perforce users. Use groups to set access levels in the p4 protect form, limit the maximum amount of data that can be accessed from the server by particular users within a single command, and to set the timeout period for p4 login tickets.

To delete a group, use p4 group -d groupname, or call p4 group groupname and remove all the users from the resulting form.

Form Fields

Field Name
Type
Description

Group:

Read-only

The name of the group, as entered on the command line.

MaxResults:

Writable

The maximum number of results that members of this group can access from the server from a single command. The default value is unlimited. See the Usage Notes below for more details.

MaxScanRows:

Writable

The maximum number of rows that members of this group can scan from the server from a single command. The default value is unlimited. See the Usage Notes below for more details.

MaxLockTime

Writable

The maximum length of time (in milliseconds) that any one operation can lock any database table when scanning data. The default value is unlimited. See the Usage Notes below for more details.

Timeout:

Writable

The duration (in seconds) of the validity of a session ticket created by p4 login. The default value is 43200 seconds (12 hours). To create a ticket that does not expire, set the Timeout: field to 0.

Users:

Writable,
multi-line

The Perforce usernames of the group members. Each user name must be typed on its own line, and should be indented.

Subgroups:

Writable,
multi-line

Names of other Perforce groups.

To add all users in a previously defined group to the group you're presently working with, include the group name in the Subgroups: field of the p4 group form. Note that user and group names occupy separate namespaces, and thus, groups and users can have the same names.

Every member of any previously defined group you list in the Subgroups: field will be a member of the group you're now defining.

Owners:

Writable,
multi-line

Names of other Perforce users.

Group owners without super access are permitted to administer this group, provided that they use the -a flag.

Options

-a

Allow a (non-superuser) group owner to administer the group. The user must be listed in the Owner: field of the group.

-d groupname

Delete group groupname. The members of the group are affected only if their access level or maxresults value changes as a result of the group's deletion.

-i

Read the form from standard input without invoking the user's editor. The new group specification replaces the previous one.

-o

Write the form to standard output without invoking the user's editor.

g-opts

See the Global Options section.

super
(list for p4 group -o or -a)

The Perforce superuser can limit the amount of data that the server returns to the client by setting the MaxResults value for groups of users. The superuser can also limit the amount of data scanned by the server (whether returned to the client or not) by setting the MaxScanRows value, and the length of time any database table can be locked in by any single operation by setting the MaxLockTime value.

If any of the MaxResults, MaxScanRows, or MaxLockTime limits are violated, the server request fails and the user is asked to limit his query.

If a user belongs to multiple groups, the server computes her MaxResults value to be the maximum of the MaxResults for all the groups of which the user is a member (ignoring any settings still at the default value of unlimited). If a particular user is not in any groups, her MaxResults value is unlimited. (The user's MaxScanRows and MaxLockTime limits are computed in the same way.)

The speed of most server hardware should make it unnecessary to ever set a MaxResults value below 10000, a MaxScanRows value below 50000, or a MaxLockTime value below 1000.
