# COPR spec for etr. See packaging/aur/PKGBUILD.in for the sibling packaging target.
#
# THIS IS A TEMPLATE. Its Version: field is a sentinel filled in by render_packaging.py,
# .copr/Makefile runs when it builds the SRPM -- so the version comes from Cargo.toml in the
# checkout COPR cloned, and nothing in this file records a release. See that script for why
# recording it is the wrong shape.
#
# Source0 is a LOCAL tarball, not a URL. .copr/Makefile builds it from the checkout, so this
# spec needs neither a published tag nor network access to find its source:
#   - a PR can build its own SRPM, which it could not while Source0 pinned a tag tarball that
#     only exists after a release;
#   - the built package is the code COPR actually cloned, rather than a re-download that is
#     merely expected to match it.
# The rendered %changelog entry is generated in the same pass as Version:, so the two cannot
# disagree (rpmlint's incoherent-version-in-changelog).
#
# This spec is written for COPR with "Enable internet access during builds" ON, so
# `cargo build` resolves crates.io at build time and there is no vendor tarball. Two
# consequences, both deliberate:
#   1. --locked is load-bearing. With network access and no vendoring it is the only thing
#      pinning what gets resolved to what was actually tested. Never drop it.
#   2. This will NOT build in koji. Fedora proper requires offline builds, so shipping there
#      would need a vendor tarball as Source1. COPR is the endpoint.

# etr bootstraps the remote session by SSHing to the host and starting etrs there, so an ssh
# client is a genuine runtime requirement of the CLIENT rather than a nicety.
Requires:       openssh-clients
# The setgid-utmp helper that libutempter delegates to. Without it the session still works
# and simply does not appear in `last`, so this is Recommends rather than Requires -- a

%description
etr is a persistent remote shell in the mould of Eternal Terminal and mosh:
the session keeps running on the server when the network drops, and the
client reconnects transparently when it comes back.

It needs no pre-running daemon on the server. The client SSHes to the host,
starts etrs on the fly, and then connects to it over QUIC (TLS 1.3) with the
server's certificate pinned. Local and remote TCP/UDP port forwarding and
X11 forwarding are supported.

This package installs both the client (etr) and the per-session server
(etrs).

# Fedora's own rustc flags, from rust-srpm-macros. Three reasons to use them rather than
# cargo's defaults:
#   1. Hardening and codegen policy the distro expects.
#   2. They carry -Cdebuginfo=2 -Cstrip=none, which is what makes rpm's debuginfo extraction
#      work. Without them a Rust release build has no DWARF, rpm finds nothing, and the build
#      fails on an empty debuginfo package.
#   3. This is NOT "shipping a debug build" -- -Copt-level=3 is in there; rpm moves the
#      symbols into separate -debuginfo/-debugsource subpackages and strips the binary in the
#      main package.
# Deliberately NOT using rust-packaging's %%cargo_prep/%%cargo_build: those assume Fedora's
# offline, vendored-dependency workflow and write a cargo config with offline = true, which
# would fight the network-enabled build this spec is designed around.
