<?php

// This snippet must some before the "repository URLs" as is it used to
// "compute" the proper URLs for the various streams and types of builds.

// It requires, for following variables to have already been defined in outter script:
// $BUILD_ID, $STREAM_MAJOR, $STREAM_MINOR, $BUILD_TYPE, $TIMESTAMP

// It "outputs" two values:
// $STREAM_REPO_URL
// $$BUILD_REPO_URL

// "RCs" have complicated rules, but in short:
//   RC's for an initial release (in June) go from 4.x-M-build repos to 4xmilestone repos
//   RC's for SRs "stay" in the 4.x-M-build repo. And, no easy way to tell if service release,
//   from the build id alone. The hard way is to part the first "digit groups" of build id, and,
//   if service field is 0 (or does not exist) then it is not a service release.


// checking for existence is especially important for BUILD_REPOs, since they might have been removed.
// but we do it also for sanity check.
// relative patch can be either 3 or 4 "up", depending on if on downloads, or build machine.
// either can be used to "prove existence".
// We define them here, but used in "main", outter script.
