From b0a6422d03e8ef8a93ffdbcad22815b973080a40 Mon Sep 17 00:00:00 2001 From: kartikey1306 Date: Fri, 28 Aug 2026 19:18:14 +0530 Subject: [PATCH 01/16] fix: restore the package import and reconcile the merged backend behaviour `import ebuild.build.dispatch` raises SyntaxError on master, so the CLI and five test modules fail outright. As with the other breakage below, the cause is overlapping PRs squash-merged on stale bases with no re-verification. - dispatch.py: configure() ended with two consecutive `else:` blocks from an unresolved conflict. The two blocks also disagreed about the exception -- tests/ebuild expects ValueError("Unknown build backend ''") while tests/unit expects RuntimeError matching "ninja". Both are legitimate readings: an unrecognized name is a bad argument, and a "ninja" that reaches the dispatcher is a CLI routing failure. Introduced UnknownBackendError(ValueError, RuntimeError) with a message covering both, raised from configure(), build(), and clean(). "ninja" is no longer a silent no-op in configure(), which is what let `ebuild build` report "Build completed successfully" without running a compiler. - ninja_backend.py: NinjaBackend._object_path() was deleted by a cflags refactor while both of its callers survived, so generate() died with AttributeError -- the default build backend did not work at all. Restored with its target-namespaced object paths, which is what stops two targets sharing a source from claiming the same output. - ninja_backend.py: the emitted `link_shared` rule was dead -- nothing used it -- and it hardcoded `-shared`, which is wrong on macOS. Shared libraries already link through the generic `link` rule with the platform's flag (-dynamiclib/-shared) and the -L/-l wiring in ldflags. Dropped the rule and updated tests/ebuild/test_ninja_backend.py, which asserted the dead rule, to cover the surviving behaviour instead. Its removal also unblocks test_static_library_unaffected, which asserts no "-shared" anywhere in the generated file. Verified: pytest tests/ 202 passed (201 passed + 1 skipped without the ninja package installed); tests/performance 1 passed.

Every generated build.ninja was rejected before a single command ran. A POSIX path containing a space fails the same way. _ninja_path() escapes `$`, `:` and ` ` and is applied to the paths in build statements only. Variable values (cflags, ldflags) are read to end of line and are deliberately left alone -- escaping them would hand the compiler mangled flags. Also skipped tests/ebuild/test_integration_initramfs_security.py on hosts without find(1)/cpio(1). _create_initramfs() drives both directly, so on a Windows runner all three died with WinError 2 before reaching the injection behaviour they exist to check. Building a Linux initramfs is not a Windows operation; the skip matches how test_ninja_backend.py already skips when no host C compiler is present. Adds four regression tests for the escaping, including one asserting that each build statement contains exactly one unescaped colon. Verified: pytest tests/ 206 passed.

That makes recipes/*.yaml the tool's supply chain, and a recipe is a pin: a URL plus the digest of exactly what should be at it. Four of the five shipped recipes are not usable pins, and the code let them ship that way. **Four recipes cannot be fetched.** Each digest below was checked by downloading the artifact twice and hashing it; both downloads agreed. | recipe | recorded | actual | |----------|-------------------------|-------------------------| | littlefs | `sha256:placeholder` | `9cf2e7db...cad67` | | lwip | `sha256:placeholder` | `c79255f6...ed87` | | mbedtls | `...b1490fcd73` | `...b1490fcd38` | | freertos | `e36e5a2f...e3140` | `eebd58aa...271eb` | | zlib | `9a93b2b7...df23` | `9a93b2b7...df23` (ok) | mbedtls has the last two hex characters transposed. freertos matches none of the release's assets — that tag publishes exactly one, `FreeRTOS-KernelV11.1.0.zip`, 3324125 bytes, `eebd58aa...271eb`. Corrected all four. **"placeholder" parsed as a valid checksum.** `PackageRecipe.validate()` checked that the field was well-formed in no way at all, so `sha256:placeholder` sailed through and then failed every fetch with a mismatch. A checksum that is present must now look like a sha256 digest. It is deliberately still optional at the recipe level — a recipe also models packages that are never downloaded — the requirement lands at the boundary that matters, below. **No checksum meant no verification.** `PackageFetcher.fetch()` did `if recipe.checksum:` and, when absent, downloaded and extracted with nothing checked. Omitting one field silently bought an unverified download. fetch() now refuses before touching the network. `tests/ebuild/test_package_fetcher.py` contained `test_empty_checksum_skips_verification`, which asserted exactly this behaviour; it is replaced by one asserting the refusal. **Plaintext http:// was accepted.** `_download()` allowed `http://` and `https://` alike. A pin is worth much less over a transport anyone on the path can rewrite, and it leaks what is being built. https only; no shipped recipe used http. **tests/unit/test_shipped_recipes.py** walks recipes/ and asserts each one pins a syntactically real sha256 over an https URL and loads through the real loader. Against the recipes as they were, it fails on both placeholders. It deliberately does not assert digest *values*: that needs the network, and pinning them here would only duplicate the recipe.

Nothing produced those numbers. A developer had to run `size` themselves and remember which columns to add, which is not being told — it is being left to find out. $ ebuild build [ok] Build completed successfully. Flash: 1.9 KB of 1.00 MB (0.2%) RAM : 300.6 KB of 192.0 KB (156.6%) [warn] RAM usage 300.6 KB exceeds the board's 192.0 KB -- this image will not fit. The accounting matches scripts/measure_footprint.py in the eos repo so the two tools cannot disagree about what a number means: flash = text + data ram = data + bss `data` is charged to both because it is stored in flash and copied to RAM at startup; reading `size`'s "dec" column instead understates RAM. Capacity comes from the project's own board.yaml `memory.flash_size` / `ram_size` when it ships one — the convention the descriptions under hardware/board/ already use — and otherwise from a table of the reference part for each board family. Boards that boot from removable storage, and Linux-class parts with no fixed budget, are deliberately absent: a percentage against a guessed ceiling reads as authoritative, so those report absolute sizes only. An over-budget image is a warning, not a build failure. It linked; it will not fit. The developer needs to hear that now rather than from a board that will not boot. A cross build is measured with its own `size` and never falls back to the host one — host `size` on an ARM ELF reports numbers for a different target and nothing in the output would say so. Where no suitable tool exists the report is skipped rather than guessed, and never fails the build. Also fixes .gitignore, found while committing this: line 8 was a bare `build/` from the Python-packaging block, which also matched `ebuild/build/` — the source package holding dispatch.py, ninja_backend.py and toolchain.py. Those four files predate the rule and stayed tracked, but every new module added there was silently ignored, including this one. Anchored to `/build/`, which keeps the setuptools artifact directory ignored and stops the pattern reaching nested source. 235 tests pass, up from 202; 32 are new here.

charset=UTF-8 Content-Transfer-Encoding: 8bit The MLP list asks for it, and the absence shows: the same class of problem currently surfaces three different ways. A missing cross toolchain appears as a compiler-not-found partway through a build. A missing repo cache appears as `eos/hal.h: No such file`. A missing binutils silently drops the footprint report. None of the three names the fix. $ ebuild doctor OK python 3.12.14 OK ninja 1.13.2 (/usr/bin/ninja) OK host compiler 15.2.0 (/usr/bin/cc) OK arm-none-eabi 14.2 (/usr/bin/arm-none-eabi-gcc) warn xtensa-esp32-elf not installed — no esp32 builds OK eos repo ~/.ebuild/repos/eos (master) No problems. The host build path is ready. Optional, for other targets: - install the xtensa-esp32-elf toolchain to target esp32 Three decisions worth naming. Read-only. It reports; it does not repair. `ebuild setup` fetches the repos, and installing a toolchain belongs to the developer's package manager — guessing which one they use is how a diagnostic tool starts doing damage. The exit code is non-zero only for things that actually stop a build. A host-only machine legitimately has no cross toolchain, and a doctor that always exits 1 stops being consulted, which costs more than it saves. A missing cross toolchain reports the boards it would have unlocked rather than just its own absence. "arm-none-eabi-gcc not found" is a fact; "no stm32f4, stm32h7, nrf52, rp2040 or tms570 builds" is the consequence the developer is actually deciding about. `--json` emits the same checks for CI, and agrees with the text form on the exit code. 254 tests pass, up from 235; 19 are new here.

[ok] Added wifi to build.yaml That trades one clear error now for a confusing one at build time, in a file the developer has since committed. It now refuses, and says what would help: $ ebuild add wifi [error] No recipe for 'wifi'. Available: freertos, littlefs, lwip, mbedtls, zlib To add it anyway: ebuild add wifi --force $ ebuild add lwipp [error] No recipe for 'lwipp'. Did you mean: lwip? `--force` keeps the old behaviour for anyone who genuinely wants an entry ahead of its recipe, and says plainly that it will not resolve. Refusing without an escape hatch would be the other kind of unhelpful. The build then reports what it actually contained: EmbeddedOS Build OK toolchain arm-none-eabi-gcc OK board configuration stm32f4 OK lwip MISS mqtt declared, nothing resolved OK temperature-monitor executable The case worth having is MISS. A package that resolved to no include or library directory contributed nothing, whatever build.yaml says -- the build still succeeds, the feature is simply absent, and until now nothing said so. The summary is rendered through the logger in the tests, so the assertions are on what a developer actually sees rather than on an intermediate structure. 271 tests pass, up from 255; 16 are new here.

Subject: [PATCH 16/16] =?UTF-8?q?feat(cli):=20add=20`ebuild=20package`=20?= =?UTF-8?q?=E2=80=94=20assemble=20the=20eFirmware=20.efw=20image?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit §29's development-to-device flow is eBuild -> {EoS, eBoot, application} -> eFirmware artifact -> {EoSim, hardware} Every piece of that existed except the arrow into eFirmware. embeddedos-org/eFirmware implements the image format — efw_image_build, attach_signature, serialize, parse, verify — and ships efwtool to pack, inspect and verify. It builds clean and its tests pass 3/3. Nothing in ebuild referenced it: grepping the whole tool for `.efw` returned no code. A developer who wanted the artifact the flow ends at had to know the repository existed, build the tool themselves, and run it by hand. $ ebuild build [ok] Build completed successfully. Flash: 1.9 KB RAM : 2.6 KB $ ebuild package --load 0x08000000 --entry 0x08000100 Packing sensor-node -> sensor-node.efw [ok] sensor-node.efw (16140 bytes) sensor-node.efw: OK (15984 bytes, sha256 b87b8a98dd...) This drives efwtool rather than re-implementing the header in Python. The header is a packed C struct with a magic, a version, a size and a SHA-256, and a second implementation of it in another language is a second thing to keep in step — which is the failure this repository has spent the week repairing. If the format changes, the tool changes with it and this keeps working. efwtool is found on PATH first, so a developer's own build is not silently recompiled behind them; failing that, the cached eFirmware checkout is built on demand and reused. eFirmware joins eos and eboot in what `ebuild setup` fetches, since the flow now needs it. Where the tool cannot be found the command says which one applies — `ebuild setup` when the checkout is absent, the cmake invocation when it is present but unbuilt. "efwtool not found" on its own leaves the developer guessing at what fetches it. Verified end to end: the packed image round-trips byte-for-byte (156-byte header plus a payload identical to the built artifact), efwtool inspect reports image_version 2.1.0 taken from build.yaml, and verify recomputes the same SHA-256. The tests cover the wiring, not the format — efwtool owns the format and has its own tests. One of them needed the repo cache pointed at an empty directory as well as PATH cleared: this machine has a real efwtool cached, and without both the test passed by finding it and asserted nothing. 331 tests pass, up from 316. --- ebuild/build/firmware_image.py | 149 ++++++++++++++++++++++++++++ ebuild/cli/commands.py | 69 +++++++++++++ ebuild/deps/__init__.py | 102 ++++++++++--------- tests/unit/test_package_efw.py | 173 +++++++++++++++++++++++++++++++++ 4 files changed, 446 insertions(+), 47 deletions(-) create mode 100644 ebuild/build/firmware_image.py create mode 100644 tests/unit/test_package_efw.py diff --git a/ebuild/build/firmware_image.py b/ebuild/build/firmware_image.py new file mode 100644 index 00000000..79aa0128 --- /dev/null +++ b/ebuild/build/firmware_image.py @@ -0,0 +1,149 @@ +# SPDX-License-Identifier: MIT +# Copyright (c) 2026 EoS Project + +"""Assemble an eFirmware `.efw` image from a built artifact. + +§29's development-to-device flow ends: + + eBuild -> {EoS, eBoot, application} -> eFirmware artifact -> {EoSim, hardware} + +Every piece of that existed except the arrow into eFirmware.
