build: consume Dash Platform CXX bindings from depends#7623PastaPastaPasta wants to merge 3 commits into
Conversation
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 a vendor-<package>-crates target and extracts the archive before building, so cargo builds run locked and fully offline.
…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.

changed the title
…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.

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.

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.

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.

WalkthroughThe 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. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The opt-in platform build can fail on a clean checkout because its offline dependency archive is not guaranteed to be prepared before compilation. Merge should wait until the build dependency is enforced or a clear bootstrap path is provided. Sequence Diagram(s)sequenceDiagram

Require the vendor archive before the offline Cargo build.
Line 341 silently skips vendored-source setup when the archive is absent. depends/packages/platform_cxx.mk Line 29 then runs Cargo with --offline. A clean make PLATFORM_GUI=1 cannot resolve the Platform crates unless an external workflow has already restored the archive.
Make platform_cxx depend on vendor-platform_cxx-crates, or stop with a clear bootstrap instruction. If vendoring remains manual, document that required command in depends/README.md.

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.

In `depends/funcs.mk`:
- [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. This breaks `PLATFORM_GUI=1` Darwin cross-builds. Provide rustc with an executable wrapper that preserves the configured compiler command, including the environment cleanup and target/SDK arguments.
In `contrib/devtools/update-rust-hashes.py`:
- [SUGGESTION] contrib/devtools/update-rust-hashes.py:91-97: Do not require absent Rust consumer files
The updater always exits here because this revision has no repository-level `rust-toolchain.toml`. In addition, `configure.ac` contains no `RUSTC_REQUIRED_VERSION` assignment, so the updates at lines 121-122 would fail even if the existence check were bypassed. This makes the script referenced by `native_rust.mk` unusable for maintaining the new `native_rust.mk` and `rust_stdlib.mk` pins. Limit synchronization in this PR to the two depends package files, or add the consumer files and expected version assignment before requiring them.

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.aand 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.pymaintains both pins together.funcs.mk: any package declaring a vendored archive name and cargo manifest gets avendor-<package>-cratestarget; builds then runcargo build --locked --offlineagainst the extracted archive.PLATFORM_GUI=1knob: addsmbedtls,native_protobuf,tenderdash_sourcesandplatform_cxxto the package set.platform_cxxbuilds the Platform CXX bindings from the pinned commit and installslib/libdash_platform_cxx.a+include/dash/platform/.config.site.inexportsenable_platform_guiandPLATFORM_CXX_{CFLAGS,LIBS}for the configure flag that arrives with the client library PR.linux64_platform_guilane 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. Notebuild.ymlvalidates 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_cxxcurrently pins dashpay/platform#4416's head (df4fdb68559e). That PR is stacked on dashpay/platform#4388/#4389; once it merges tov4.2-devthe 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?
