# It clones the harness under ~/.dsh/source (the master clone at
|
|
# ~/.dsh/source/master), adds a per-install staging worktree at
|
|
# ~/.dsh/source/staging-<timestamp> on branch dsh-staging/<timestamp>, checks
|
|
# host dependencies (git, Node, pnpm) and offers to install a missing pnpm, runs
|
|
# `pnpm install`, points the stable `~/.dsh/source/current` symlink
|
|
# at that staging worktree and symlinks `dsh` onto PATH at `current/bin/dsh`,
|
|
# records your API credentials in the Harness home (`~/.dsh`) dsh reads at boot,
|
|
# builds the repository artifacts, and launches the Web UI. Keeping every
|
|
# checkout under ~/.dsh/source keeps successive
|
|
# upgrades in one place instead of scattered sibling clones, and lets staging
|
|
# worktrees share the master clone's object store. The PATH symlink resolves through
|
|
# `current`, so an upgrade repoints one stable symlink instead of relinking PATH:
|
|
# the `dsh` on PATH never moves and can never dangle.
|
|
#
|
|
# When run from inside an existing checkout (e.g. `sh scripts/install.sh` rather
|
|
# than `curl ... | sh`) it never clones and never touches that working tree;
|
|
# DSH_REF is ignored. Instead it *adopts* the checkout: `git rev-parse
|
|
# --git-common-dir` resolves the repository behind it (for a linked worktree that
|
|
# is the real clone, not the worktree), and a fresh staging worktree branched
|
|
# from the checkout's HEAD lands in the source container beside `current`. The
|
|
# container owns staging worktrees and `current`; the clone is discovered, not
|
|
# owned, so an arbitrary clone (~/src/dsh) and a managed one converge on one
|
|
# layout and stay upgradable. Adoption carries committed work only: the staging
|
|
# worktree branches from HEAD, so uncommitted changes stay in the checkout.
|
|
# Setting DSH_SOURCE to a different directory opts back into the normal
|
|
# clone/worktree path.
|
|
#
|
|
# Adopting an arbitrary clone leaves the container not self-contained: its
|
|
# staging worktrees hold an absolute gitdir pointer into that clone, so deleting
|
|
# it breaks them. `git worktree list` in that clone is the record of which
|
|
# worktrees depend on it.
|
|
#
|
|
# When run through `curl | sh` the script text arrives on stdin, so every

# --- path helpers ---------------------------------------------------------------
|
|
# Every path comparison below runs on physical paths. Git always reports resolved
|
|
# paths, so comparing one against an unresolved path disagrees whenever a symlink
|
|
# sits anywhere above the checkout — a symlinked home directory is enough, and
|
|
# macOS reaches every mktemp path that way through /var -> private/var. The
|
|
# mismatch silently misclassifies an existing managed install as a foreign clone
|
|
# and builds a second container beside the real one.
|
|
# `git rev-parse --path-format=absolute` would do this, but it needs git 2.31+.
|
|
#
|
|
# A not-yet-created directory (the container on a fresh install) has no physical
|
|
# path. Falling back here rather than at each call site keeps every caller a
|
|
# plain assignment, so no site can compare against an empty path by forgetting

# its own fallback.
