Issue being fixed or feature implemented

DashPay (the Platform GUI: usernames, contacts, contact payments) needs GroveDB proof verification, DPP document handling and state-transition construction from Dash Platform's own Rust implementation. Per the architecture decision on the composite branch, that Rust code lives in the Platform repository (dashpay/platform#4416, packages/rs-platform-cxx) and Dash Core consumes it as a prebuilt static library — no Rust code is vendored into this repository.

This PR is the build foundation for that: it teaches depends to produce libdash_platform_cxx.a and its headers from a pinned dashpay/platform commit, fully offline and hash-verified.

What was done?

  • native_rust / rust_stdlib: pinned prebuilt Rust toolchain as a native package plus the precompiled standard library for every supported cross target; contrib/devtools/update-rust-hashes.py maintains both pins together.
  • Per-package crate vendoring in funcs.mk: any package declaring a vendored archive name and cargo manifest gets a vendor-<package>-crates target; builds then run cargo build --locked --offline against the extracted archive.
  • PLATFORM_GUI=1 knob: adds mbedtls, native_protobuf, tenderdash_sources and platform_cxx to the package set. platform_cxx builds the Platform CXX bindings from the pinned commit and installs lib/libdash_platform_cxx.a + include/dash/platform/. config.site.in exports enable_platform_gui and PLATFORM_CXX_{CFLAGS,LIBS} for the configure flag that arrives with the client library PR.
  • CI: a linux64_platform_gui lane builds depends with the knob on (generating/caching the vendored-crates archive in the cache-sources producer) and builds dash-qt against the enriched prefix. Note build.yml validates PRs with the base branch's workflow (pull_request_target), so the lane runs on this branch's push CI now and takes effect for PRs once merged: see the push CI run.

Default path is untouched: with the knob off, the depends package set is byte-identical to develop (make -C depends print-packages).

Pin caveat: platform_cxx currently pins dashpay/platform#4416's head (df4fdb68559e). That PR is stacked on dashpay/platform#4388/#4389; once it merges to v4.2-dev the pin + hash here will be refreshed to the merged commit before this PR merges (or as an immediate follow-up if we choose to merge sooner).

How Has This Been Tested?

  • Full make -C depends PLATFORM_GUI=1 on aarch64-apple-darwin produces and installs the archive + headers; knob-off package set verified unchanged.
  • The composite integration branch — from which these changes are extracted — runs this exact depends stack plus the downstream consumer in a fully green CI matrix, including the linux64_platform_gui lane with --enable-platform-gui (49/49 checks on head 119a0239).
  • The linux64_platform_gui lane in this PR runs on the branch's push CI (link above).

Breaking Changes

None. Everything is behind PLATFORM_GUI=1, which nothing sets by default.

P1 Badge Require the vendored archive before building offline

On a fresh checkout, make -C depends PLATFORM_GUI=1 never invokes vendor-platform_cxx-crates, and the vendored archive is not one of platform_cxx's fetched sources. Silently skipping this block therefore leaves Cargo without .cargo/config.toml or the vendored registry, after which the package's cargo build --offline cannot resolve its dependencies. The CI workflow happens to generate or restore the archive separately, but the documented depends knob is unusable for ordinary fresh builds unless the archive is made a prerequisite or generated as part of the normal build graph.

P1 Badge Preserve the Darwin compiler wrapper for Rust linking

When cross-building a Darwin target in the Guix environment, depends/hosts/darwin.mk deliberately prefixes the compiler with env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH; taking only firstword consequently sets Rust's linker to env, not to clang, so rustc invokes env with linker arguments and the Platform library cannot link. Even outside that environment this also discards the Darwin compiler's --target and sysroot arguments, so the Rust linker should use a wrapper that retains the complete configured compiler command.

P2 Badge Stop requiring nonexistent Rust consumer files

Running the newly documented contrib/devtools/update-rust-hashes.py in this commit always exits here because the repository contains no rust-toolchain.toml; configure.ac also has no RUSTC_REQUIRED_VERSION assignment for the later update. As a result, maintainers cannot use the script to update either of the Rust depends pins it was added to maintain. Limit synchronization to files present in this change, or add the expected consumer files before making them mandatory.

Walkthrough

The change adds Platform GUI dependency packages, Rust compiler and standard-library downloads, Cargo vendoring, and offline Platform C++ builds. It adds configure-site integration and Guix ELF interpreter patching. CI now caches or transfers Rust vendor archives and runs dedicated Linux Platform GUI dependency, source-build, and test jobs. A utility updates Rust archive hashes and version pins.

Priority: ⚪ Not assessed

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 9b7b7

The opt-in Platform GUI dependency build can create invalid or truncated Rust vendor archives, causing offline builds and later retries to fail. These archive-generation defects should be fixed before merge; the hash-update utility also needs bounded downloads.

Preliminary review — Codex only

The opt-in Platform build is not self-contained on a clean checkout because the required crate archive is outside the normal dependency graph, and Guix Darwin cross-builds select env rather than Clang as rustc's linker. The Rust hash updater is also unusable at this head because it unconditionally requires consumer-side files that are not present.
Source: reviewer backend model gpt-5.6-sol (general and dash-core-commit-history roles); final verifier backend model gpt-5.6-sol. openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] depends/funcs.mk:341-346: Make the vendored archive part of the normal build graph
  The preprocess step silently skips vendored-source setup when the archive is absent, while neither `platform_cxx` nor its preprocess stamp depends on `vendor-platform_cxx-crates`. A clean `make -C depends PLATFORM_GUI=1` therefore proceeds without `vendored/` or `.cargo/config.toml` and reaches `cargo build --locked --offline`, which cannot resolve the dependencies. `make ... download` has the same gap, and the CI lane works only because its source-cache workflow invokes the vendor target separately. Because the skipped preprocessing is then stamped complete, creating the archive after the failed build does not extract it without cleaning the package. Model the archive as a required source or generated prerequisite of preprocessing instead of treating its absence as optional.
- [BLOCKING] depends/funcs.mk:201-208: Preserve the Darwin compiler wrapper for Rust linking
  Guix exports `C_INCLUDE_PATH` and `CPLUS_INCLUDE_PATH`, causing `depends/hosts/darwin.mk` to define the Darwin compiler as `env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH <clang> ...`. Applying `firstword` to that command sets rustc's linker to `env`, so rustc invokes `env` with object and linker arguments rather than invoking Clang.

Fixed in e42c902. The archive is now a real file target — $(SOURCES_PATH)/<package>-vendored.tar.gz, with the vendor recipe as its rule — and a hard prerequisite of both the package's preprocess stamp and download-one, so neither a clean make -C depends PLATFORM_GUI=1 nor make download can reach the offline cargo build without it; vendor-<package>-crates remains as a phony alias. Extraction is now unconditional (the if test -f skip is gone), and because the stamp depends on the archive by mtime, creating the archive after a failed attempt re-triggers preprocessing instead of being ignored.

Verified locally from a fully clean tree (no work dir, no prefix, archive deleted): make auto-vendored during the dependency walk, then completed the locked offline cargo build and cached the package.

Fixed in e42c902 (machinery) and 97c428a (package patch). RUSTFLAGS now points rustc's linker at a rustc-linker.sh installed from the package's patches during preprocessing, which exec $CC "$@" — cargo's environment already carries the full configured compiler command line, including the Guix env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH prefix and the target/SDK arguments, so nothing is lost to firstword. Build scripts are unaffected: cargo applies RUSTFLAGS only to cross-target units when --target is passed.

(An earlier iteration generated the script from an inline echo; that ran into make treating #!/bin/sh's # as a comment inside the variable, so the wrapper ships as a patch file like cargo-config.toml, which also keeps it in the package's recipe hash.)

Fixed in e42c902. The script now synchronizes only the two depends package files (native_rust.mk hashes, rust_stdlib.mk hashes and version) and no longer requires or edits rust-toolchain.toml / configure.ac — those consumers don't exist at this revision. If a later PR introduces an in-tree Rust consumer, re-adding that synchronization can come with it.

P2 Badge Provision patchelf before requiring it in Guix

When PLATFORM_GUI=1 is built inside the project's Guix environment, ls resolves under /gnu/store, so this branch exits unless patchelf is available; however, the package list in contrib/guix/manifest.scm does not include patchelf. Consequently, the new native_rust package cannot reach its staging step in a Guix build. Add patchelf to the Guix manifest or avoid making it mandatory there.

P2 Badge Redownload invalid Rust stdlib archives

If one of these downloads is interrupted, or an existing archive is corrupt, the destination file remains in place; every subsequent make PLATFORM_GUI=1 download takes the -f branch, fails the checksum, and never invokes the downloader again. Use the existing temporary-download-and-rename pattern (or delete a file after a checksum mismatch) so the depends source cache can recover without manual cleanup.

Preliminary review — Codex only

The three prior findings are fixed at the exact head: vendoring is now part of the build graph, the Rust linker wrapper preserves the complete compiler command, and the hash updater only references present consumers. Two new blockers remain in the Guix path because the manifest provides neither the mandatory patchelf executable nor the libz runtime required by the pinned Rust compiler; the all-target Rust stdlib downloader also cannot recover from a partial or corrupt cached archive.

Preliminary review — GLM Flash blocker gate

At head 4ec0caf, the Rust stdlib cache-recovery issue is fixed, but the opt-in Platform GUI toolchain still cannot be staged in the project's Guix environment because the manifest provides neither patchelf nor zlib. The new Guix detection also misses profile-prefixed executable symlinks, and native_rust retains two unused staging variables.

Source: reviewer 1: glm-5.3-flash (agent: phase1-reviewer, role: general); reviewer 2: glm-5.3-flash (agent: phase1-reviewer, role: dash-core-commit-history); final verifier: gpt-5.6-sol (agent: sol-verifier, role: verifier)

Validated blockers were found by the Phase-1 GLM Flash review and confirmed by a fresh Sol verifier. Phase 2 is deferred until a fresh same-head revalidation clears the blocker gate.

  • Phase 1 reviewers (GLM Flash): glm-5.3-flash — general (completed); agent phase1-reviewer, glm-5.3-flash — dash-core-commit-history (completed); agent phase1-reviewer

  The staging script exits when patchelf is unavailable in the project's Guix environment, but contrib/guix/manifest.scm neither imports patchelf nor includes it in the packages->manifest list. Consequently, a PLATFORM_GUI=1 depends build using that environment fails while staging native_rust, before Cargo can run. Add patchelf to the Guix manifest; commits 437e8be56e9 and 4330d067543 contain the corresponding manifest fix on another branch but are not ancestors of this head.

  Commit 4ec0caf4ee8 correctly changed a missing runtime library from a warning to a fatal staging error in Guix, but contrib/guix/manifest.scm still does not include zlib. Its LIBRARY_PATH is limited to GCC outputs, and gcc -print-file-name cannot supply libz.so.1 there. Because the pinned compiler's librustc_driver requires libz.so.1, native_rust now fails loudly rather than caching a broken toolchain. Add zlib to the Guix manifest.

native_rust installs the pinned prebuilt Rust toolchain as a native package and rust_stdlib provides the precompiled standard library for every supported cross target; contrib/devtools/update-rust-hashes.py maintains both pins together.

funcs.mk gains a cargo environment wired to the depends cross toolchain and a per-package crate-vendoring template: any package that declares a vendored archive name and a cargo manifest gets its vendored-crate archive modeled as a real make target, created by cargo vendor when absent and required by the package's preprocess stamp and by make download, so a clean build can never reach the offline cargo build without vendored sources. Preprocessing extracts the archive and generates a rustc linker wrapper that preserves the full configured compiler command (target and sysroot flags, and any env prefix), since -C linker= takes a single executable.
…I knob

PLATFORM_GUI=1 adds mbedtls, native_protobuf, tenderdash_sources and platform_cxx to the package set. platform_cxx builds libdash_platform_cxx.a and its installed headers from a pinned dashpay/platform commit (packages/rs-platform-cxx), offline via the per-package vendored crates. config.site.in exports enable_platform_gui and PLATFORM_CXX_{CFLAGS,LIBS} discovery for the configure flag that arrives with the first C++ consumer.
…lane

The new lane builds depends with PLATFORM_GUI=1 (producing and hash-verifying the Platform CXX archive offline from vendored crates), then builds dash-qt against that prefix and runs the unit tests. The cache-sources producer generates and caches the platform-cxx vendored-crates archive, handing it to same-run consumers as an artifact on cache miss.

The --enable-platform-gui configure flag is added to this lane's BITCOIN_CONFIG by the Platform client library PR; until then the lane proves the depends knob and prefix link-compatibility. build.yml runs PR validation from the base branch (pull_request_target), so the lane first runs on push CI for this branch and takes effect for PRs after merge.
The all-target rust-std downloader wrote directly to the final source-cache path and treated any existing file as complete, so a partial file left behind by an interrupted download made every subsequent 'make PLATFORM_GUI=1 download' fail on the same archive until it was removed by hand. Verify an existing archive against the pinned hash and re-fetch it when it does not match, downloading to a temp path and only moving a verified archive into place, matching fetch_file_inner.
…ry is missing

Inside a Guix environment there are no default loader search paths, so a toolchain staged without libgcc_s/libz next to it is nonfunctional and would be cached in that state. Treat a missing required runtime library as a staging failure there, consistent with the existing fatal patchelf check; outside Guix it remains a warning since the system loader can still resolve the libraries.
The linker wrapper carries a shebang, so the lint-files check requires the executable bit; cargo invokes it through the RUSTFLAGS -C linker= path either way.

P2 Badge Expose zlib before making its absence fatal in Guix

When PLATFORM_GUI=1 is built in Guix after patchelf is provisioned, this new fatal branch requires every hard-coded loop entry to be discoverable. However, contrib/guix/manifest.scm does not provision zlib and contrib/guix/libexec/build.sh sets LIBRARY_PATH only to GCC output directories, so libz.so.1 leaves LIB_SRC empty and native Rust staging exits. Fresh evidence relative to the earlier patchelf comment is this newly added fatal per-library check; provision/expose zlib or determine the staged binaries' actual DT_NEEDED libraries before failing.

See the reply on the thepastaclaw thread above: zlib provisioning belongs to #7672 with the rest of the Guix enablement, and 7f9bd41 makes the manifest's libz.so.1 discoverable through GUIX_ENVIRONMENT since build.sh deliberately narrows LIBRARY_PATH. Verified against the toolchain's actual DT_NEEDED entries (libLLVM.so.21.1 and rust-lld both need it).

Final validation — Phase 2 only (queue backlog)

Two vendoring dependency defects break source-cache-only builds and source-free installation of cached binary packages. The new native Rust staging path also requires tools and runtime-library exposure missing from the project's Guix environment. Verification used the exact-head source, workflow and manifest inspection, and local fixtures exercising the actual Make templates; no full Platform or Guix build was run.

Source: reviewer 1: gpt-6-astra (agent: phase2-reviewer, role: general); reviewer 2: gpt-6-astra (agent: phase2-reviewer, role: dash-core-commit-history); final verifier: gpt-6-astra (agent: astra-verifier, role: final-verifier)

Review provenance

  • Triage: critical by gpt-6-astra (effort low) — This adds a substantial cross-platform Rust dependency pipeline spanning shared depends logic, offline vendoring, hash verification, ELF interpreter patching, and CI cache production and consumption, requiring careful review for supply-chain integrity, reproducibility, and unintended build regressions despite the opt-in feature knob.
  • Phase 1 reviewers: not run (skipped for throughput: 26 PRs queued, above the 10 limit)
  • Fresh verifier: gpt-6-astra — final-verifier; agent astra-verifier
  • Phase 2 reviewers: gpt-6-astra — general (completed, effort xhigh); agent phase2-reviewer, gpt-6-astra — dash-core-commit-history (completed, effort xhigh); agent phase2-reviewer

  When a build restores the source cache without a built native_rust package, staging the toolchain creates a cached archive newer than the restored vendor archive.

Make consequently tries to recreate this missing prerequisite even when the package's cached archive and checksum already exist. This affects `.github/workflows/build-src.yml`, which restores only built packages before rebuilding the depends prefix: the new dependency forces Platform source fetching and vendoring into a binary-cache consumer, making that operation fail without network access.

With `PLATFORM_GUI=1` in the project's isolated Guix environment, staging therefore exits at this check. Installing patchelf alone does not complete the setup: the later mandatory runtime-library loop also requires `libz.so.1`, while the manifest does not expose zlib and `contrib/guix/libexec/build.sh` resets `LIBRARY_PATH` to GCC toolchain directories. Provision patchelf and make the required native runtime libraries discoverable alongside these fatal checks so the new Guix staging path can succeed.

Fixed in 758b315. The archive's prerequisites are order-only now: the native_rust cache and the fetch stamp still gate its creation, but their timestamps no longer schedule a re-vendor of an archive whose name already pins its content. Reproduced with a dry run before the change (touching the native_rust cache scheduled "Vendoring platform_cxx crates..."), and confirmed the same dry run is silent after it.

Fixed in 758b315: the archive is now declared .SECONDARY next to its preprocess edge. Reproduced with an empty SOURCES_PATH against a populated BASE_CACHE: before the change the dry run scheduled the Platform tarball fetch plus vendoring; after it, nothing is scheduled. With no cache and no archive, vendoring still runs as before.

Partially applied. The manifest itself is out of scope here: no Guix path sets PLATFORM_GUI=1 in this PR, and the patchelf + zlib provisioning ships in #7672 together with the knob plumbing. The discoverability half is real, though, and applies even once zlib is in the manifest: build.sh narrows LIBRARY_PATH to the gcc-toolchain outputs, so a manifest-provided libz.so.1 is invisible to both existing lookups. 7f9bd41 adds a fallback to the profile union guix shell exposes as GUIX_ENVIRONMENT. For the record, readelf -d on the x86_64 1.92.0 tarball shows libz.so.1 is a hard dependency of libLLVM.so.21.1 and rust-lld, so the loop's entries match the actual DT_NEEDED set.

lint-shell-locale requires every tracked shell script to opt out of locale dependence as its first statement.
The vendored-crates archive is named by the package version, so its content never changes for a given pin. Its prerequisites (the native_rust cache and the package's fetch stamp) are needed for availability only: make them order-only so a freshly staged toolchain does not schedule a re-vendor of crates that are already on disk, which broke offline consumers that restored the source cache before building native_rust.

Declare the archive .SECONDARY like the other depends intermediates so that a consumer holding only the built package cache (build-src.yml restores nothing else) is not forced to fetch Platform sources and vendor crates it will never use.
command -v reports the PATH entry, which in a profile-linked Guix environment lives outside /gnu/store; resolve it so the fatal checks still fire there.
native_rust stages files with cp rather than Rust's install.sh, so the stage options were never consumed.

contrib/guix/libexec/build.sh narrows LIBRARY_PATH to the gcc-toolchain outputs, so a library provisioned by the manifest (zlib for libLLVM and rust-lld) is invisible to the existing gcc and LIBRARY_PATH lookups and the Guix-fatal check fires even when the library is installed. Fall back to the profile union guix shell exposes as GUIX_ENVIRONMENT.

P2 Badge Write vendor archives atomically

If tar fails after creating the archive—for example, because the source-cache filesystem fills up—GNU make leaves this partial target in place because .DELETE_ON_ERROR is not enabled. On the next invocation the archive is newer than its order-only prerequisites, so vendoring is skipped, check-sources does not validate this generated file, and preprocessing repeatedly fails while extracting it until the user deletes it manually. Write to a temporary path and rename only after successful completion, as the Rust stdlib downloader does.

Fixed in 7661126: the archive is written to <name>.temp and renamed on success, matching the rust-std downloader.

depends does not enable .DELETE_ON_ERROR, so a tar that fails mid-write (disk full) leaves a truncated archive that satisfies the rule on the next run and breaks every later preprocess. Write to a temporary path and rename on success, as the rust-std downloader does.

Write the vendor archive atomically.

If tar fails after creating $$($(1)_vendored_archive), the partial archive remains. Its order-only prerequisites do not force a rebuild, so a later Make run can reuse the partial archive and fail during extraction. Create a temporary archive, then rename it to $$($(1)_vendored_archive) only after tar succeeds.

Separate the vendor archive command from the staging pipeline.

Line 265 passes @cd to the shell as a command. Make only strips @ at the start of a recipe line. The directory change therefore fails, and find vendored runs from the staging directory. This can create an empty or invalid vendor archive.

Put the vendor archive command on its own recipe line. Keep the staging find pipeline separate.

P2 Badge Exclude vendor archives from the broad source cache

When this dedicated cache key changes without the platform commit—and therefore the archive filename—changing, such as after editing funcs.mk or cargo-config.toml, the preceding broad depends/sources restore can repopulate the old vendor archive from its exact or fallback cache. A miss here does not remove that file, so the subsequent make sees the real archive target already present, skips cargo vendor, and saves the stale archive under the new dedicated key. Exclude these archives from the broad cache or delete them when this cache misses before regenerating them.
