chore: build against minio-cpp 1.0.0, which installs as libminio

[harshavardhana]

Builds against minio-cpp 1.0.0, which installs the library as libminio with a stable soname. minio-go's cgo
directive is now -lminio (minio/minio-go#2302), so the pin has to move here too.

Ref pin. Moved in lockstep across the three places that carry it -- .github/workflows/go-rdma.yml,
scripts/build-rdma.sh, scripts/setup-rdma-release-host.sh. Compiling against 1.0.0 headers while linking a
0.6.0 archive fails by naming a missing symbol, not a version, so a half-moved pin is expensive to diagnose.

Link line. scripts/rdma-cgo-libs.txt is the single source of truth -- the workflow, build-rdma.sh and
qreleaser.yaml read it, and setup-rdma-release-host.sh derives its prefix checks from it -- so renaming
-lminiocpp there propagates to all four.

Brotli. 1.0.0 builds cpp-httplib with brotli support and 0.6.0 did not: the installed libminio.a carries 7
undefined Brotli* symbols where libminiocpp.a carried none, so the link fails without the archives. vcpkg
already produces them and the prefix already receives them; only the list was missing. This is the part that would
have turned up as a red go-rdma job rather than at review.

Upgrade path. setup-rdma-release-host.sh moves a pre-1.0.0 libminiocpp.* aside. Its stale sweep globs the
name it installs, so without this an already-provisioned host keeps the old archive in the same -L as the new one.

libs3rdma needs no separate change. minio-cpp vendors it, so this pin carries it from 0.3.0 to 0.3.1 for both
architectures, and the soname stays libs3rdma.so.0 -- the name the release packaging copies out -- so
pkg-scripts/rdma-contents.yaml and release-post-transform.sh are untouched.

How to test

Verified on a release host that still held the 0.6.0 install, so the upgrade path was exercised rather than a
clean one:

bash scripts/setup-rdma-release-host.sh
# >>> moving 2 stale amd64 file(s) aside to /usr/local/lib/warp-rdma-backup-<ts>
# >>> /usr/local satisfies the RDMA link line for amd64
# >>> amd64 smoke build links and targets Advanced Micro Devices X86-64
# >>> arm64 smoke build links and targets AArch64
# >>> release host provisioned and link-tested for: amd64 arm64

Both architectures rebuilt at 1.0.0, both smoke builds link, and the resulting binary is clean:

$ readelf -d warp | grep NEEDED
  libs3rdma.so.0   libstdc++.so.6   libm.so.6   libgcc_s.so.1   libc.so.6   ld-linux-x86-64.so.2

No libminiocpp, libminio statically linked as intended, libs3rdma.so.0 the only non-system dependency.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The RDMA build now uses minio-cpp v1.0.0, links libminio with Brotli libraries, updates the Go dependency, and updates host-library replacement handling.

Changes

RDMA library upgrade

Layer / File(s)	Summary
Version and library contract .github/workflows/go-rdma.yml, scripts/build-rdma.sh, scripts/setup-rdma-release-host.sh, go.mod	Build workflows and scripts now use minio-cpp v1.0.0 and refer to the installed library as libminio. The minio-go dependency also updates.
RDMA linking integration scripts/rdma-cgo-libs.txt	The linker uses -lminio, removes the curl libraries, and adds the Brotli libraries.
Host library replacement scripts/setup-rdma-release-host.sh	Host validation checks libminio.a. Host setup installs system zlib for native and arm64 builds. Replacement logic skips the vcpkg zlib archive and backs up current, legacy, and orphaned dependency archives.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 91d95

The RDMA build now targets minio-cpp v1.0.0 and libminio successfully for the default configuration, but custom older MINIO_CPP_REF values can break provisioning and linking. Restricting unsupported overrides or retaining the legacy contract would remove this bounded compatibility risk.

Force-pushed. The first push failed Build rdma on both arches with cannot find -lcurlpp / cannot find -lcurl, which turned out to be the more interesting half of this bump.

minio-cpp 1.0.0 changes its dependency set, not just the library name: it replaces curlpp with cpp-httplib, and takes zlib from the system on Linux instead of vcpkg. Comparing the manifests:

	0.6.0	1.0.0
HTTP	curlpp (+curl)	cpp-httplib[openssl] → pulls brotli
zlib	all platforms	windows only

vcpkg for 1.0.0 builds exactly brotli{common,dec,enc}, crypto, ssl, inih, INIReader, pugixml — no curl, no curlpp, no libz. So scripts/rdma-cgo-libs.txt had to drop -lcurlpp -lcurl as well as gain the brotli archives, and the prefix checks had to stop demanding a libz.a that is no longer produced.

Worth recording why my first local verification passed while CI failed: the release host still had libcurl.a, libcurlpp.a and libz.a sitting in the prefix from the 0.6.0 provisioning, so the link silently used them. A clean runner has none. That is also why the orphan sweep in setup-rdma-release-host.sh is unconditional rather than tied to the library having changed — an orphaned libz.a is the one that misleads, since it still satisfies -lz and makes the local link differ from the released one.

Re-verified with the orphans swept, so the prefix now holds only what 1.0.0 produces:

>>> /usr/local satisfies the RDMA link line for amd64
>>> /usr/local/aarch64-linux-gnu satisfies the RDMA link line for arm64
>>> amd64 smoke build links and targets Advanced Micro Devices X86-64
>>> arm64 smoke build links and targets AArch64
>>> release host provisioned and link-tested for: amd64 arm64

$ readelf -d warp | grep NEEDED
  libs3rdma.so.0  libz.so.1  libstdc++.so.6  libm.so.6  libgcc_s.so.1  libc.so.6  ld-linux-x86-64.so.2

libz.so.1 is now a dynamic dependency rather than statically linked, which is the correct outcome on Linux for 1.0.0.

Review feedback addressed

Applied 1 fix across 1 file from 1 review finding.

The stale sweep globbed libminio.*, which also matches the libminio.so* files the shared-object sweep below
collects, because static_libs() now yields minio after the rename. A prefix holding a shared object from an
older install queued the same path twice, and the second mv failed on an already-moved source — under set -e,
aborting provisioning before anything was installed.

Confirmed rather than assumed, with the two globs isolated in a harness:

• old libminio.* — mv: cannot stat …libminio.so, exit 1, install step never reached
• new libminio.a — 3 paths, exit 0, reaches install

Then exercised end to end on a release host: planted a libminio.so and forced the changed-build path so the sweep
actually ran. Provisioning completed, moved 4 stale files aside with no errors, both prefixes satisfied the link
line, and both the amd64 and arm64 smoke builds linked.

Scoped narrower than the suggested edit: only the archive is swept under the current name, leaving libminio.so*
to the sweep that exists for it. libminiocpp.* stays a glob, since static_libs() no longer yields miniocpp
and nothing else covers the pre-1.0.0 shared objects.
