# slosh — macOS code-signing & notarization
#
# The mechanism is the project's and lives here. Everything specific to *you* —
# which team, whose certificate, which mac — is in macos-release.mk, which is
# gitignored; copy macos-release.mk.example to it and fill it in.
#
# The signing happens on a dedicated mac (see docs/macos-release.md). From here you
# normally never run the pipeline directly — you drive that machine, and this
# end needs only ssh, rsync and make, so "here" may be a Linux box:
#
#     make macos-dist                      # the main Makefile forwards to here
#     make macos-dist REF=v0.2.0           # ...for a pushed ref
#
# which is this file's remote-dist target, and can also be run directly:
#
#     make -f Makefile.macos remote-dist   # sync this tree → build → sign →
#                                          # notarize there → fetch the zip back
#     make -f Makefile.macos builder-check # is the builder still set up?
#
# The targets below (build/sign/zip/notarize/dist) are what actually runs *on*
# the builder. They still work on any mac that holds the identity, which is how
# this started; the difference is that they now name a keychain explicitly,
# because a build machine nobody logs into has no unlocked login keychain.
#
# One-time setup of a new builder, from here:
#
#     contrib/macos-builder-setup m1       # toolchain, clone, keychain, notary
#
# ── your identity ───────────────────────────────────────────────────────────
# Not in this file: TEAM_ID, SIGNER and BUILDER come from macos-release.mk, so
# that the rest of this is the project's and can be shared. `-include` because
# a checkout without one is normal -- most people never sign anything -- and
# the targets that actually need it say so themselves (require-identity).
# A command-line override still beats both.

# so the actual Apple ID / password / API key never live in this file.
NOTARY_PROFILE ?= slosh-notary

# ── the keychain ────────────────────────────────────────────────────────────
# Both the signing key and the notary credential live in a keychain of their
# own rather than in login.keychain. On the builder that is not a preference:
# nobody ever logs in there, so the login keychain is never unlocked, and
# codesign over ssh fails with a bare "User interaction is not allowed". A
# separate keychain with a password we can read from a 0600 file is unlockable
# from a non-interactive shell, and holds nothing but slosh's signing material.
#
# If that keychain is absent we fall back to the default search list, so this
# file still behaves the old way on a machine where you sign by hand.
