p4 group

Synopsis

Syntax

Description

• They can be used within p4 protect to set access levels for multiple users, and

• They control the maximum amount of data that can be accessed from the server by particular users within a single command.

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.
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.

Options

-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.

• As the number of files in the depot grows, certain commands can significantly slow down the server if called with no parameters, or if called with non-restrictive arguments. For example, p4 print //depot/... will print the contents of every file in the depot on the user's screen, and p4 filelog //depot/... will attempt to retrieve data on every file in the depot at every revision.

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 for groups of users.

If either of the maxresults or maxscanrows 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 value is computed in the same way.)

The speed of most server hardware should make it unnecessary to ever set a maxresults value below 10,000, or a maxscanrows value below 50,000.

The commands that are affected by the maxresults and maxscanrows values are:

Command	Counted Entity	How Affected Users Can Reduce Command Output
p4 changes	changes	Using p4 changes -m numchanges.
p4 changes files	file revisions	Use a more restrictive file pattern on the command line.
p4 diff2	files	Use a more restrictive file pattern on the command line.
p4 filelog	file revisions	Use a more restrictive file pattern on the command line.
p4 files	files	Use a more restrictive file pattern on the command line.
p4 fixes	fixes	The -c changenum or -j jobname flags restricts this command appropriately.
p4 fixes files	files	Use a more restrictive file pattern on the command line.
p4 integrate	files	Use a more restrictive file pattern on the command line.
p4 integrated	file revisions	Use a more restrictive file pattern on the command line.
p4 jobs	jobs	The -e jobquery flag restricts the output to those jobs that meet particular criteria.
p4 jobs files	file revisions	Use a more restrictive file pattern on the command line.
p4 labelsync	files	Use a more restrictive file pattern and the -a flag to build the label's file set in pieces.
p4 print	files	Use a more restrictive file pattern on the command line.
p4 sync	files, as mapped through client view	Use a more restrictive file pattern on the command line.
