If used, this script owns and manages the membership of the group named 'limits'. This script's job is only to ensure that users are in the group. It is expected that the Perforce Admin will apply appropriate values to the Max* settings of the group spec for the limits group. Settings such values causes limits to be applied. Until limits are applied, membership in the limits group has no impact. See 'p4 help group' for more information, and also see: * https://portal.perforce.com/s/article/2521 * https://portal.perforce.com/s/article/2529 BE CAREFUL: Setting the values requires judgement and experience. If Max* values are set too low, users will be unduly impacted, and will see errors indicating that they have exceeded limits such as MaxScanRows or MaxOpenFiles. Appropriate values depend on various factors such as server hardware resources and Helix Core date size; there are not "one size fits all" values. For users that should not have limits applied, create a group no_limits, and add users (perhaps certain trusted automation users) to that group. Set the Max* values for that group to the special value 'unlimited'.

Fixed bug where script will hang if 'iconv' hangs, which can happen if certain Unicode characters exists that may appear in a user's FullName field. The fix was to remove the 'iconv' utility entirely, thus eliminating the risk of a hang. The 'p4 users' command was instead optimized to use 'p4 -ztag -F %User% users' to get just the needed list of users, so that the FullName fieled is not displayed to begin with (and thus no need for Unicode tranlsation). Also changed shebang line to reference python3 rather than python. Also improved docs. #review-29927 robert_cowham |

@tom_tyler @russell_jackson Bug fix for running p4master_run as root, and some comment header cleanup. Job 000543 p4master_run: Preserve original arguments list and use this when exec'ing as $OSUSER. backup_functions.sh: Add text about sourcing p4_vars yourself instead of using p4master_run. update_limites.py: Run p4login directly without p4master_run since p4login calls p4_vars now. everything else: Remove comment block about needing to run with p4master_run. Reword comment about SDP_INSTANCE since it is not always an integer value. |

#2 | 12169 | Russell C. Jackson (Rusty) |
Updated copyright date to 2015 Updated shell scripts to require an instance parameter to eliminate the need for calling p4master_run. Python and Perl still need it since you have to set the environment for them to run in. Incorporated comments from reviewers. Left the . instead of source as that seems more common in the field and has the same functionality. |
