redis/scripts/deploy.sh

#!/bin/sh
# deploy.sh — build (via scripts/build.sh) then copy artifacts to $(PREFIX).
#
# Usage:  scripts/deploy.sh [<name> ...|all|.|'*'|redis|none]
# Env:    PREFIX    install root (default /usr/local). Files land in:
#                     $PREFIX/bin/                  - redis-server, -cli, -benchmark
#                     $PREFIX/lib/redis/modules/    - per-module .so files
#         DESTDIR   optional staging root prepended to PREFIX (for packaging).
#         MAKE      make binary (defaults to `make`); only used when shelling
#                   into build.sh, which itself respects it.
#
# Tokens:
#   (no args) | all | . | '*'   build + install Redis + every cloned module
#   redis | none                 Redis only
#   <name> [<name> ...]          Redis + the listed modules
#
# Flow:
#   1. Delegate build to scripts/build.sh — same orchestration the user gets
#      from `make` (failure collection, redis-full.conf refresh, etc.).
#   2. After build, copy artifacts into place ourselves (NOT via each
#      module's `install` target). This keeps the install step a pure copy
#      and avoids depending on per-module Makefile install recipes.
#
# Failures during build are surfaced from build.sh; failures during copy are
# collected and reported at the end of this script.

#   1. PREFIX env shadow — so anything reading $PREFIX in build.sh / scripts
#      it spawns sees the empty value.
#   2. MAKEFLAGS — when the user runs `make deploy PREFIX=…`, the parent
#      make smuggles PREFIX through MAKEFLAGS, and any recursive `make` we
#      spawn would re-apply it as a command-line variable (which beats env).
#      Strip just the PREFIX=… token from MAKEFLAGS so the rest (e.g. -j8)
#      still propagates normally.
# Our local $PREFIX (in this script's scope) is untouched and reused for
# the copy + apply-redis-conf phases below.

# Tolerate a non-zero exit from build.sh: it returns 1 when any one module
# fails to build, but other modules may have succeeded (or have artifacts left
# over from prior successful builds). The per-module existence check in
# phase 2 below filters out modules that genuinely don't have a .so to copy,
