The tree by what each part is, behind the top-level Makefile: - shims/ -> hosts/ (the browser, kernel, native and Wayland hosts) - web/ -> page/ (the page's source, build and serve), ports/mesa, ports/xwayland and ports/tint (the ports the page loads), site/ (static sites and the eject page) - tools/gexcc -> toolchain/gexcc, with the sysroot and busybox builds from tools/wine-wasm in toolchain/sysroot and toolchain/busybox, and one toolchain/pins (musl, the LP64 musl, LLVM, busybox) - tools/wine-wasm -> wine/: dist.sh (was wine64-dist.sh), wine.pins (64-bit Wine, and the 32-bit tree its wineserver builds from), libs.pins (the Unix libraries), the 32-bit-only pieces in wine/legacy32 (its own pins and legacy.mk, which wine/Makefile includes) - tools/*.py and tools/*.sh -> scripts/ (the GL generators in scripts/gl) - wine32/src.sh is scripts/fetch-pinned.sh, which takes the trees the old script marked as its own References follow the moves: paths from the tree's root by the map, paths from a script's own directory by where their target went.

# OUT gets COMMIT's tree. Without --worktree it is a plain tree (git archive,
|
|
# no .git) with OUT/.pinned naming the commit; with --worktree it is a git
|
|
# worktree of the mirror, detached at COMMIT, for builds that read git (the
|
|
# 64-bit Wine dist keys its steps by the tree's commits). Nothing happens when
|
|
# OUT is already at COMMIT. The mirror is a bare repository, made on first
|
|
# use, and fetched from only when it lacks COMMIT: by the commit itself (shallow: its tree, not its history), then,
|
|
# if the server will not serve a bare commit, every branch. GEX_SRC_SEED=DIR,
|
|
# a local clone of the same repository, is fetched from first, so a machine
|
|
# with a worktree of the fork needs no network.
