Introduce `--mirror` and `DCRUP_MIRROR` so `dcrup` can fetch prebuilt binaries from multiple CDNs. Default `auto` tries cf → gh → sf → ya and uses the first successful download. - dcrup.sh / dcrup.ps1: mirror chain, CLI flag, env override - remove install.sh / install.ps1 / install_bsd.sh (superseded by dcrup) - GitHub Actions: upload releases to Cloudflare R2 next to Yandex S3 - docs: README, FAQ, changelog, installation, env vars, contributing

dcrup — install and switch DCR versions
|
|
|
|
Usage:
|
|
dcrup install <spec> [--build|--release] [--force] [--libc gnu|musl|auto] [--mirror auto|cf|gh|sf|ya]
|
|
dcrup default <spec>
|
|
dcrup update
|
|
dcrup list
|
|
dcrup show
|
|
dcrup which
|
|
dcrup uninstall [<spec>|--all]
|
|
dcrup self-install [--to DIR]
|
|
dcrup help
|
|
|
|
Spec:
|
|
stable | dev | night
|
|
VERSION → VERSION@stable (e.g. 0.8.2)
|
|
VERSION@stable
|
|
VERSION@dev
|
|
night → always build from branch "dev" HEAD
|
|
|
|
Modes:
|
|
--release download prebuilt binary (default for stable/dev)
|
|
--build cargo build --release --features archive
|
|
night always --build (prebuilt not available)
|
|
|
|
Linux libc (prebuilt triple only):
|
|
--libc gnu x86_64-unknown-linux-gnu (default)
|
|
--libc musl x86_64-unknown-linux-musl
|
|
--libc auto musl if host ldd/libc is musl, else gnu
|
|
|
|
Mirrors (prebuilt download only):
|
|
--mirror auto try cf → gh → sf → ya, first successful download wins (default)
|
|
--mirror cf download from cdn-global.dcr-tool.ru
|
|
--mirror gh download from github.com/dexoron/dcr
|
|
--mirror sf download from sourceforge.net/projects/dcr-tool
|
|
--mirror ya download from cdn-ru.dcr-tool.ru
|
|
DCRUP_MIRROR env override (default: auto)
|
|
|
|
Env:
|
|
DCRUP_HOME default ~/.dcr
|
|
DCRUP_BIN default $DCRUP_HOME/bin
|
|
DCR_FEATURES default archive
|
|
DCRUP_REPO git/GitHub repo URL
|
|
DCRUP_LIBC gnu|musl|auto (default: gnu)
|
|
DCRUP_MIRROR auto|cf|gh|sf|ya (default: auto)
