# Makefile.node_prebuilt.defs: Makefile for including a prebuilt Node.js build.
#
# NOTE: This makefile comes from the "eng" repo. It's designed to be dropped
# into other repos as-is without requiring any modifications. If you find
# yourself changing this file, you should instead update the original copy in
# eng.git and then update your repo to use the new version.
#
#
# This Makefile facilitates downloading and bundling a prebuilt node.js
# build (using the 'sdcnode' distro builds). This is an alternative to
# the "Makefile.node.*" makefiles for *building* a node from source.
#
# Usage:
#
# - Define `NODE_PREBUILT_VERSION` in your Makefile to choose a node version.
# E.g.: `NODE_PREBUILT_VERSION=v0.6.19`. See other optional variables
# below.
# - `include tools/mk/Makefile.node_prebuilt.defs` after this in your Makefile.
# - `include tools/mk/Makefile.node_prebuilt.targ` near the end of your
# Makefile.
# - Have at least one of your Makefile targets depend on either `$(NODE_EXEC)`
# or `$(NPM_EXEC)`. E.g.:
#
# node_modules/restify: deps/restify $(NPM_EXEC)
# $(NPM) install deps/restify
#
# or better, use an order-only dependency to avoid spurious rebuilds:
#
# node_modules/restify: deps/restify | $(NPM_EXEC)
# $(NPM) install deps/restify
#
# - Use `$(NPM)` or `$(NODE)` to use your node build.
# - Include the "$(NODE_INSTALL)" tree in your release package.
#
#
# When including this Makefile, you MUST also specify:
#
# NODE_PREBUILT_VERSION The node version in the prebuilt 'sdcnode'
# package to use. Typically this is one of the
# node version tags, e.g. "v0.6.18" but it
# can be any commitish.
#
# When including this Makefile, you MAY also specify:
#
# NODE_PREBUILT_DIR The dir in which to find sdcnode builds. This
# can either be a *local directory* or *a
# URL* dir (with trailing '/') which serves
# Apache/Nginx dir listing HTML.
# (default: sdcnode master build dir on stuff)
#
# NODE_PREBUILT_TAG The 'sdcnode' project supports special
# configuration builds of node, e.g. say a
# build configured `--without-ssl`. These
# special configurations are given a tag, e.g.
# 'gz', that is used in the filename. Optionally
# specify a tag name here.
# (default: empty)
#
# NODE_PREBUILT_BRANCH Specify a particular branch of 'sdcnode' builds
# from which to pull. Generally one should stick
# with the default.
# (default: master)
#
# NODE_PREBUILT_IMAGE If you have a zone image that differs from that
# for an sdcnode build that you want to use (potential compat
# issues be damned), then set this to the UUID of the sdcnode
# build you want. See here for available build image uuids:
# <https://download.joyent.com/pub/build/sdcnode/master-latest/sdcnode/>
#
# BUILD top-level directory for built binaries
# (default: "build")
#
# NODE_INSTALL where node should install its built items
# (default: "$BUILD/node")
#
#
# Dev Notes:
#
# This works by getting "NODE_PREBUILT_NAME" from the provided "NODE_PREBUILT_*"
# vars and the image version (via 'mdata-get sdc:image_uuid'). The image uuid is
# included to ensure an exact match with the build machine. This name (e.g.
# "v0.6.18-zone-$uuid") is used to find a matching "sdcnode-$name-*.tgz" build
# in "NODE_PREBUILT_DIR" (either a local directory or a URL). That tarball is
# downloaded and extracted into "NODE_INSTALL".
#
# The "*_EXEC" vars are set to named symlinks, e.g.
# "build/prebuilt-node-v0.6.18-$uuid", so that a change of selected node
# build (say the developer changes NODE_PREBUILT_VERSION) will recreate the
# node install.
#
# See <https://mo.joyent.com/docs/sdcnode/master/> for details on 'sdcnode-*'
# package naming.
