Refinements to @27712: * Resolved one out-of-date file (verify_sdp.sh). * Added missing adoc file for which HTML file had a change (WorkflowEnforcementTriggers.adoc). * Updated revdate/revnumber in *.adoc files. * Additional content updates in Server/Unix/p4/common/etc/cron.d/ReadMe.md. * Bumped version numbers on scripts with Version= def'n. * Generated HTML, PDF, and doc/gen files: - Most HTML and all PDF are generated using Makefiles that call an AsciiDoc utility. - HTML for Perl scripts is generated with pod2html. - doc/gen/*.man.txt files are generated with .../tools/gen_script_man_pages.sh. #review-27712 |

Non-functional change: Fixed a common doc type: paramter -> parameter |
||
#7 | 20448 | C. Thomas Tyler |
Fixed env bug seen when running init scripts as root. Updated *_base scripts and *_init script templates to a new standard. Goals: 1. Init scripts that use corresponding *_base scripts are minimized so that do nothing more than set SDP_INSTANCE and then call the corresponding *_base script. 2. The 'su' commands always pass $* instead of $1, deferring all processing to the *_base script. 3. The shell environment is now guaranteeds to have the same results regardless of whether it is called as 'root' or as the defined OSUSER. 4. The p4_vars file is always sourced exactly once. Two calls to 'source p4_vars' appear in some cases, one immediatley before the su/exec call, and another after the after the 'su/exec'. Only one or the other is sourced. 5. All init scripts have a reasonably consistent usage message. 6. All init scripts accept a 'status' argument. This change fixes a bug where 'p4broker_N_init status' run as the 'perforce' user would report many pids unrelated to Perforce if run as root, e.g. doing 'service p4broker_N_init status'. This also eliminates a potential issue where the 'perforce' user might source a p4_vars with a default instance in ~/.profile or ~/.bashrc, thus invalidating the instance specified when the user ran the init script as root. |

@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. |

Routine merge to dev from main using: p4 merge -b perforce_software-sdp-dev |

#4 | 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. |

#3 | 12028 | C. Thomas Tyler | Refreshed SDP dev branch, merging down from main. | ||
#2 | 11466 | Russell C. Jackson (Rusty) |
Initial work to simplify p4_vars and remove cluster stuff. Testing of named instances surfaced some bugs that are in prod sdp, now fixed in dev. Added three triggers from RCJ SDP Moved p4review.cfg into the new /p4/common/cfg to go along with the instance_vars files. mkdirs.sh now generates an instance_p4review.cfg as well. Removed incremental p4verify to clean up a bit. It didn't support replicas and was really never used. All port settings now live in <instance>_vars file. You set what you want the ports to be in mkdirs.sh. There is no more fancy logic to try to guess what the port should be. You set it, and that is what it is. Remaining to do is to updated scripts to not need p4master_run. Saved that work for later since this is tested and works. |
