USAGE -------- 1. Run p4review2.py --sample-config > p4review.conf 2. Edit the file p4review.conf 3. Add a crontab similar to this: * * * * * python2.7 /path/to/p4review2.py -c /path/to/p4review.conf FEATURES --------- * (!!) Prevent multiple copies running concurrently with a simple lock file. * Logging support built-in. * Takes command-line options. * Configurable subject and email templates. * Can (optionally) include URLs for changelists/jobs. Examples for P4Web included. * Use P4Python when available and use P4 (the CLI) as a fallback. * Option to send a __single__ email per user per invocation instead of multiple ones. * Reads config from a INI-like file using ConfigParser * Have command line options that overrides environment variables. * Handles unicode-enabled server **and** non-ASCII characters on a non-unicode-enabled server. * Option to opt-in (--opt-in-path) reviews globally (for migration from old review daemon). * Configurable URLs for changes/jobs/users (for swarm). * Able to limit the maximum email message size with a configurable. * SMTP auth and TLS (not SSL) support. * Handles P4 auth (optional, not recommend!). Nice to haves (TODOs) ----------------------- * Include P4Web link for diffs. * Respect protection table (for older P4D versions). See: http://public.perforce.com/guest/lester_cheung/p4review/p4review.py for a previous attempt. * Supports hooks from the changelist description to notify additional users/email. * Skip review email for change authors [done] and job modifiers [todo]. The later is not recorded in the job spec by default so it must be a configruable... * run as a standalone daemon (UNIX and Windows). See this recipe for an implementation on Windows: http://code.activestate.com/recipes/576451-how-to-create-a-windows-service-in-python/ DISCLAIMER ----------- User contributed content on the Perforce Public Depot is not supported by Perforce, although it may be supported by its author.
