Enhanced P4DTG init script: * Now removes 'stop' file on startup, eliminating a manual step. * Provides useful error message if a P4DTG error file is found. * Provides a '-f' flag to move P4DTG error file aside and start anyway, but with a good error message telling the user to review the error file first. (Typically errors are just related to p4d being down.) * Made 'stop' wait for and confirm shutdown. * Made 'stop' error out if already stopped. * Made 'start' error out if already started. * Made 'restart' robust (by making stop wait for confirmed shutdown). * Cosmetic and output tweaks. |

#6 | 20491 | C. Thomas Tyler |
Fixed an environment insulation bug in init scripts. More testing (and thinking) revealed that the only way to truly provide a guarantee of insulation from user-set defaults in ~perforce/.bashrc (etc.) is to pass SDP_INSTANCE as a parameter to the *_base scripts, so that the instance name is explicitly passed into the su/exec call (when run as root). This change also includes minor cleanup in init scripts and *_base scripts. |

#5 | 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. |

#4 | 20341 | C. Thomas Tyler |
Tweaked all init scripts to default to 'status' (rather than an ugly syntax error) of the user forgets the start/stop/status parameter, as was done previosly for the broker init script. Removed unnecessary 'source' call when calling p4<whateve>_base scripts. Cleaned up comments. |
