p4pcm.pl v1.1.7: Adjusted shebang line. The prior shebang line forced usage of /p4/common/perl/bin/perl. At one point in history that was more reliably available, when building a self-contained Perl in the SDP was more common. But no longer. The shebang line now finds perl from PATH. The default SDP path still prefers /p4/common/perl/bin, so if a perl exists there it will be used. This change will have no functional impact to existing installations that have and user /p4/common/perl, but will not require new installstions to build a self-contained perl. #review-29302 |

Refinements to @27712: * Resolved one out-of-date file (verify_sdp.sh).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 |

Fixed off-by-three-orders-of-magnitude error in Proxy cleanup script.
The key change is to adjust the output of a stat() call, dividing the numeric value in bytes returned by 1024 to get the number of Kilobytes. This script makes use of the Perl stat() function, the details of which are helpful: https://perldoc.perl.org/functions/stat.html See also: SDP-191 and change @21751. This was an earlier change that detected the bytes/Kilobtyes confusion, and addressed it by adjusting the default threshhold values from the baseline version. This change change undoes that method of addressing the problem, rolling back to the original defaults for thresholds. Now with the calculation adjusted to use KB rather than bytes, the original change is no longer needed. #review @amorriss |

#5 | 21751 | tom_tyler | Merged Erik's change to dev. | ||
#4 | 19250 | tom_tyler |
SDP-ified:
* Now puts the p4pcm.log file in $LOGS dir. * No longer requires '-d' flag if $P4PCACHE environment variable is defined. Also did some internal refactoring. To Do: The log just grows and is not rotated. |

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

#2 | 12169 | russell_jackson |
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. |
