maskRootdir() built its strip-regex from this process's os.tmpdir(), so
it only masked paths whose root matched the current tmpdir. That is
fragile in two real cases:
- The path being masked is recorded when the compile runs and need not
share the masking process's tmpdir. Snapshots/fixtures that freeze
/tmp/... paths only mask on hosts where os.tmpdir() is /tmp (they fail
where it is e.g. /usr/tmp).
- On macOS os.tmpdir() returns /var/folders/... while real temp paths
often resolve via /private/var/folders/..., so masking silently missed.
- A configured temp root (temp dirs created outside os.tmpdir()) was
never matched at all.
Key the regex off the distinctive ce_temp_prefix marker instead,
matching whatever path segments precede it. This is tmpdir-independent
and unifies the Windows and non-Windows branches into one rule (also
masking embedded temp paths like `-I/tmp/.../include` on Windows, which
the old anchored branch missed).
Adds unit tests for maskRootdir (previously untested) covering /tmp,
/usr/tmp, macOS /private/var, Windows, the -I include case, and non-temp
paths left untouched.

This patch adds support for viewing the abstract syntax tree (AST) of
Python source code in Compiler Explorer, matching the existing AST
viewer feature for C/C++ (Clang AST).
- This patch adds a helper script `ast_dump.py` that parses and dumps
the AST for a Python source code file. `python -m ast` should also work,
but it's not available in old versions of Python.
- This patch adds an AST parser for Python which mimics the structure of
the C/C++ AST parser. It also updates the Python compiler to enable AST
output.
- All existing and new tests pass.

Adds CE properties entries so the new compiler versions installed in
compiler-explorer/infra#2230 appear in the UI. Companion to
**compiler-explorer/infra#2230**.
Follows existing patterns exactly — no existing entries removed, no
existing IDs changed. `defaultCompiler` for each affected group is
bumped to the newest added version.
## Versions added
| Language | File | New versions | IDs |
|---|---|---|---|
| Crystal | `crystal.amazon.properties` | 1.20.3 | `crystal1203` |
| Nim | `nim.amazon.properties` | 2.0.16, 2.2.10 | `nim20016`, `nim2210`
|
| Pony | `pony.amazon.properties` | 0.52.5 → 0.67.0 (16 releases) |
`p0525`…`p0670` |
| TinyGo | `go.amazon.properties` | 0.41.1 | `tinygo0411` |
| Rakudo | `raku.amazon.properties` | 2025.06.1, 2025.08, 2025.10–12,
2026.01–06 | `rakudo-moar-2026-06-01` etc. |
| Wasmtime | `wasm.amazon.properties` | 46.0.1 | `wasmtime4601` |
| Sway | `sway.amazon.properties` | 0.69.6, 0.70.3, 0.71.2 |
`swayv0696`, `swayv0703`, `swayv0712` |
| Sail | `sail.amazon.properties` | 0.19.1, 0.20.2 | `sail_0_19_1`,
`sail_0_20_2` |
Note: the Rakudo 2025.06 release is the `2025.06.1-01` point release,
added as `rakudo-moar-2025-06-1-01` (name *Rakudo 2025.06.1 MoarVM*) to
mirror infra, following the existing `2021-02-1-01` special-case
pattern.
## Not included: Kotlin/Native
infra#2230 also installs Kotlin/Native 2.3.0–2.4.0, but there is
currently **no `kotlin-native` language or properties file in CE** (only
`kotlin` (JVM) and `android-kotlin`). Surfacing Kotlin/Native would
require a new language definition + compiler backend, which is out of
scope for a properties update — so it's left out of this PR and can be
handled separately.
## Testing
Ran local discovery for each affected language (`node app.ts --language
<lang>`) with stub binaries at the expected install paths, and confirmed
CE resolves and creates each new compiler ID (config parses, exe path
resolves, version gathered). The pre-commit `test:props` validation
suite passes (90/90).

Part of the actionlint rollout across CE repos
(compiler-explorer/compiler-workflows#68, compiler-explorer/infra#2226).
[actionlint](https://github.com/rhysd/actionlint) statically checks
workflow files: schema/typos, expression type-checking against real
contexts (undefined inputs/outputs/needs are errors), unknown runner
labels, and shellcheck over embedded `run:` scripts.
This repo has no pre-commit framework, so it's wired as a small CI
workflow that runs on any push/PR touching `.github/workflows/**`, using
the pinned official docker image. `.github/actionlint.yaml` declares the
self-hosted `admin` label so `runs-on: [admin]` (deploy workflows)
checks correctly.
The existing ten workflows already pass with no findings.

Adds SDCC 4.6.0 to the C compiler list. Requested because 4.6.0 is the
first C compiler release to support the `_Optional` type qualifier.
Follows the existing SDCC group convention exactly: appends `sdcc460` to
`group.sdcc.compilers` and adds the `exe`/`semver` entries. No existing
IDs changed.
Depends on the infra install PR landing first:
compiler-explorer/infra#2228
Verified the 4.6.0 tarball installs via `ce_install`, `bin/sdcc
--version` reports `4.6.0`, and a `_Optional int *p;` program compiles
cleanly. The properties validation suite passes (`npm run test:props`,
90 tests).

*(I'm Molty, an AI assistant acting on behalf of @mattgodbolt)*
## Problem
Compilers in the `clangx86trunk` group that set their own `options`
property silently **override** the group-level
`options=--gcc-toolchain=/opt/compiler-explorer/gcc-snapshot`. The
per-compiler value is checked first; if found, the group fallback is
never reached.
This means ~18 compilers (all those with a per-compiler `options` line —
e.g. `clang_hana`, `clang_bb_p2996`, `clang_p2998`, `clang_patmat`,
`clang_resugar`, `clang_barry`, `clang_concepts`, etc.) fall back to the
system GCC 13 instead of `gcc-snapshot`. System GCC 13's libstdc++ lacks
headers like `bits/version.h`, so any user who switches these compilers
to `-stdlib=libstdc++` gets:
```
fatal error: 'bits/version.h' file not found
```
Reported via: https://compiler-explorer.com/z/WcPd19b5o (hana-clang, but
confirmed broken on all affected compilers).
## Fix
Move the toolchain flag from `group.clangx86trunk.options` to
`group.clangx86trunk.baseOptions`. The `baseOptions` and `options`
values are **concatenated** rather than one replacing the other, so
per-compiler `options` no longer silently discard the toolchain.
`clang_p1144` and `clang_lifetime` intentionally use different GCC
toolchains, so they get their own `baseOptions` override with the
correct path. The toolchain flag is removed from their `options` entries
(which now only contain the non-toolchain flags).
## Testing
Verified via CE compile API with `-v` that:
- Affected compilers (e.g. `clang_hana`) currently select
`/usr/lib/gcc/x86_64-linux-gnu/13` instead of `gcc-snapshot`
- `clang_trunk` (no per-compiler options) correctly gets `gcc-snapshot`
today
- Explicitly passing
`--gcc-toolchain=/opt/compiler-explorer/gcc-snapshot` as a user flag
fixes the affected compilers, confirming the root cause

Fixes#8896.
### What was happening
`SharingBase.ensureUrlIsNotOutdated()` replaces the page URL with
`httpRoot` (`/`) once the layout state diverges from the state recorded
after load. That rewrite exists for the main site, so an outdated
shortlink path (`/z/...`) doesn't linger in the address bar after you
edit the code.
Since #8166 started running the shared state-tracking (`SharingBase`) in
embedded mode too — to keep the "Edit on Compiler Explorer" link in sync
— the rewrite also fires inside `/e` iframes. There, `location.pathname`
(`/e`) never equals `httpRoot` (`/`), so the first state change after
load (an edit, or just layout churn) silently rewrites the iframe's URL
to `/` — dropping both the `/e` path **and** the state hash. Reproduced
with a `history.replaceState` spy: after two edits in an embed, the
iframe's location is `/` with an empty hash.
The visible symptoms are then browser-dependent, which is why it looked
intermittent: Firefox restores an iframe's *session-history* URL when
the parent page reloads, so the iframe comes back as `godbolt.org/` —
the full site, showing the default language example, and (because
cookies are unreadable in a cross-site iframe, per the `privacy_status`
SameSite console error in the report) the privacy-policy popup. Chrome
reloads iframes from their `src` attribute, so it never showed the
problem.
### The fix
Skip the rewrite entirely in embedded mode — the iframe's URL *is* the
embedded state and must never be touched. The `a.link` "Edit on Compiler
Explorer" state tracking from #8166 is unaffected.
### Tests
New `cypress/e2e/embed.cy.ts`:
- the embedded state's code loads (not the default example),
- the `/e#state` URL survives state changes (fails before this fix:
pathname becomes `/`, hash emptied),
- the "Edit on Compiler Explorer" link still picks up edits (locks in
#8166's behaviour).

It lowers to the exact value as limited by lint-staged package. For some
reason, the value is chosen to be the current LTS value at the time of
this
[PR](https://github.com/compiler-explorer/compiler-explorer/pull/8885)
even though the value is dictated by lint-staged package.
Follow up of
https://github.com/compiler-explorer/compiler-explorer/pull/8849
Thanks a lot for the review and merge !
I did not realize that scale/1.7.1 does not support cuda>13.1 as I was
testing locally with cuda/12.8.0, see
https://godbolt.org/z/cjdvYqGbd
> nvcc: warning: CUDA version is newer than the latest supported version
13.1 [-Wunknown-cuda-version]
The fix is straightforward and included in this PR. AMD backend seems
good. Sorry for the noise :)

Hi !
This PR adds the [scale nvcc
compiler](https://docs.scale-lang.com/stable/) to the CE live site for
both AMD and Nvidia backends
It works locally and shows host asm, device LLVMIR and:
- PTX ans SASS for Nvidia backend,
- AMDGPU code for AMD backend.
There is a bug in scale 1.7.1 that prevents the compilation with both
`-S, -o` flags. As a result I had to make some temp workarounds.
For Nvidia backend, PTX is written in the device `.s` file. I run it
through `ptax` and `nvidasm` to get the SASS. To get the LLVMIR, I
decode the device `.bc` file with `llvm-dis`.
For AMD backend, the `.s` file is the AMDGPU code, and the LLVMIR is
obtained the same way.
I plan to make the `.ts` script closer to say `nvcc.ts` once the flag
bugs are fixed in scale.
Let me know if there is anything I missed for the live site integration.

## What
Fresh rollup of minor/patch dependency updates via `npm update -S`, plus
a
`biome.json` tweak, plus a **node floor move to the latest 22 LTS**.
Redo of #8844
on top of current `main`.
Notable dep bumps: `@aws-sdk/*` 3.1057→3.1079, `@sentry/*` 10.55→10.63,
`webpack` 5.107→5.108, `@biomejs/biome` 2.4.16→2.5.2, `cypress`, `sass`,
`lint-staged`, and others.
## biome `!**/*.svg`
biome 2.5 now parses `.svg` files as HTML and errors on them (94 errors
across
`static/**`/`public/**`). Added `!**/*.svg` to the biome ignore list.
## Node floor → 22.23.1 (latest 22 LTS)
The update pulled `lint-staged@17.0.8`, which requires node `>=22.22.1`
— above our
previous declared minimum of `22.12.0`. Per the #8845 `find-node`
contract,
`.node-version` is the single source of truth whose satisfaction must
also satisfy
`engines.node` and every dependency. To keep that true, this bumps:
- `.node-version` → `22.23.1`
- `engines.node` → `>=22.23.1`
22.23.1 is the current latest 22 LTS and is also what CI's `setup-node`
(`22.x` +
`check-latest`) already resolves to. **Production node should move to
match.**
Lockfile regenerated cleanly under node 22.23.1 / npm 10.9.8 (CI's
toolchain).
## No `webpackJsHack` bump
The original #8844 also bumped `webpackJsHack` to dodge a source-map CDN
hash
collision; #8848 removed that escape hatch entirely (infra#2188 exempted
source
maps). So this touches no `webpack.config.esm.ts`.
## Note on the earlier biome CI failure
An earlier push failed `test` with `Cannot find module
'@biomejs/cli-linux-x64/biome'`.
Investigated: the lockfile is complete (all 8 platform optional deps
present, biome
2.5.2's package metadata is byte-identical to 2.4.16 which passes on
`main`), it
installs fine under npm 10.9/11.8 locally, and node 22.23.1 satisfies
all engines.
This is the known nondeterministic npm optional-dependency install flake
(npm/cli#4828) under node-22's bundled npm 10.9 — not a lockfile/code
defect. It
resolves on re-run; the systemic fix (make CI install with the repo's
declared
`npm@11.2.0` via corepack) is out of scope here.
Supersedes #8844.

> [!IMPORTANT]
> **Draft / do not merge yet.** Depends on
[infra#2188](https://github.com/compiler-explorer/infra/pull/2188) being
merged **and deployed** first. Until then, this `webpackJsHack` constant
is still the only escape hatch for the source-map hash collisions, so it
must stay. There's no deadline on this PR — it's pure cleanup that can
wait indefinitely.
## What
Removes the `webpackJsHack` `.vNN.` infix from the static asset
filenames (`[name].vNN.[contenthash].js` → `[name].[contenthash].js`,
and likewise for `.css` and worker files), along with its now-misleading
"Hack alert" comment.
## Why
This constant was a **manual escape hatch**. The CDN serves static files
with a one-year immutable cache and verifies (in CI, `ce ... builds
check_hashes`) that a given filename never changes content. Source maps
are named after their *asset's* content hash (`<asset>.map`), so a
toolchain bump that regenerated a map for byte-identical JS/CSS reused
the same `.map` filename with different bytes → the check failed, and we
manually bumped this constant to rename every asset and dodge the
collision.
[infra#2188](https://github.com/compiler-explorer/infra/pull/2188) fixes
the root cause: source maps are debug-only metadata, not code, so
they're now exempt from the immutable-hash check, overwritten on deploy,
and served `no-cache` (so debugging always gets the current map). With
that deployed, this constant can never need bumping again.
## The comment was true once — on webpack 4 — but has been obsolete
since the webpack 5 upgrade
The "Hack alert" comment claims the bumps are needed for *"webpack
changes that affect how minification is done, even though that's
supposed not to matter."* That was accurate when it was written, but
stopped being true years ago:
| When | webpack | What | Minification claim valid? |
|------|---------|------|---------------------------|
| 2020-04-18 (`67575197f`, *"Add a hacky fix for the cannot upload over
identical file"*) | **4.42.1** | Comment + manual version introduced;
template changed `[chunkhash]` → `v2.[contenthash]` | **Yes** |
| 2021-12-21 (`7c20613c5`, *"Move to using webpack5 (#3197)"*) |
**5.65.0** | Upgrade to webpack 5 | **No — obsolete from here on** |
- **On webpack 4** there was no `realContentHash`; JS hashes were
computed from the chunk's module content *before* Terser ran. So a
webpack/minifier change that altered the *minified* output left the hash
unchanged → same filename, different bytes → "cannot upload over
identical file". The manual version was a genuine fix, and the comment
correctly described pre-minification hashing.
- **Since webpack 5** (`realContentHash: true`, default-on in
production, landed in 5.8) every `[contenthash]` is recomputed from the
**final, post-minification** bytes. A minifier change now produces a
*new filename* on its own — it can no longer collide. So the
minification rationale has been dead for ~3.5 years.
That means essentially every version bump from the webpack-5 era onward
(the `v2 → … → v69` march) was a **source-map** collision misattributed
to minification — the source map being the one asset whose name still
isn't a hash of its own post-processed content. That is exactly what
infra#2188 addresses.
### Net
- A real code change or a minifier change → different post-minification
bytes → different `[contenthash]` → new filename. Handled correctly by
content-addressing; no hack needed.
- The only same-name-different-bytes case was source maps → fixed by
infra#2188.
- So removing `webpackJsHack` (and its misleading comment) is safe once
infra#2188 is deployed.

## What
Reworks the bespoke `etc/scripts/find-node` and its `Makefile`
interaction so node discovery works out of the box on Linux and macOS,
is optionally friendly to version managers, and stays sympathetic to
people who just use system node.
### Before
- Only ever looked at `PATH`, plus a vestigial
`/opt/compiler-explorer/node` hardcode (an affordance for one dev's
local setup, unused by the live site).
- Duplicated the required node version in three places (`find-node` had
`22` twice; `.node-version`; `package.json` `engines`).
- Silently fell back *past* an unusable `NODE_DIR` to whatever else it
found.
- nvm users got whatever default was active, not the version this repo
pins.
- Nagged on any version that wasn't exactly `22.x`, even newer ones.
### After — clear, permissive resolution order
1. **`$NODE_DIR/bin/node`** — explicit override, now authoritative. If
it's set but missing/too old you get a clear error instead of a silent
fallback.
2. **`node`/`nodejs` on `PATH`** — covers system node *and* any version
manager with shell integration (fnm, asdf, nodenv, volta, an active
nvm). Zero extra steps on a well-configured machine.
3. **Manager rescue** — only when PATH node is absent or below the
minimum: source `nvm` and ask for the pinned version (the one manager
that's a shell function rather than a PATH binary), then try
`fnm`/`nodenv`/`asdf`. Each branch is inert unless that tool is
installed, so nobody is pushed onto a manager.
Other changes:
- **Single source of truth**: the minimum major now comes solely from
`.node-version` (the same file the managers read). Newer majors are
always fine — the "only tested against v22.x" warning is dropped.
- **`Makefile`**: `.node-bin` now also depends on `.node-version`, so
bumping the pin re-resolves node instead of serving a stale cache. The
lazy-dotfile pattern (so failures abort `make` and `make help` pays
nothing) is kept.
- **`README`**: documents the PATH-first + manager-rescue behaviour.
## Testing
- `shellcheck` clean.
- Verified: PATH discovery, valid/bogus `NODE_DIR`, nvm rescue (shadowed
`node`+`nodejs` with v18 shims → skipped them and resolved v22.22 via
nvm), too-old fallthrough, no-node/no-manager failure message, and `make
info` end-to-end.
- `fnm` branch is logically straightforward but was not exercised (no
fnm on the test box) — worth a smoke test if you have one.

## What & why
We used to enforce the BSD-2-Clause license banner on every source file
via `eslint-plugin-header`. That check was lost when we migrated from
ESLint to Biome (#7033), which has no equivalent rule. This PR
reinstates it as a standalone node script, modelled on the existing
`etc/scripts/check-frontend-imports.js`.
### Why a script rather than a Biome rule
Biome 2.x has no built-in license/header rule and no plugin equivalent
to `eslint-plugin-header`; its experimental GritQL plugins aren't suited
to whole-file-prefix matching. A script needs zero new dependencies and
gives full control over scope and exemptions.
## The check (`etc/scripts/check-license-headers.js`)
A file "has an appropriate banner" if, ignoring an optional shebang, it
opens with a `// Copyright (c) …` line **and** contains the BSD-2-Clause
disclaimer body. The year and copyright holder are intentionally **not**
constrained — the tree legitimately has many holders (Compiler Explorer
Authors, Arm, Microsoft, HRT, individuals). The `(c)`/`(C)` marker is
matched case-insensitively.
**Scope:** `.ts/.js/.mjs/.cjs` under `lib/ static/ shared/ types/ test/
cypress/`.
**Exempt:** generated files (`lib/asm-docs/generated`), vendored
(`docenizer/vendor`), `.d.ts`, and three third-party ports that carry
their own upstream license — `static/ansi-to-html.ts` (MIT),
`lib/node-graceful.ts` (MIT), `shared/rison.ts` (Nanonid/rison port).
**Wired into:** CI (`test-and-deploy.yml`), `npm run check`, the `make
pre-commit` target, the husky pre-commit hook, and `lint-staged` (per
staged file).
Usage:
```
node ./etc/scripts/check-license-headers.js # scan the tracked tree
node ./etc/scripts/check-license-headers.js <files...> # scan specific files (lint-staged)
```
## Backfill
The check surfaced **42 CE-authored files** missing the banner. This PR
backfills them all with the standard `Copyright (c) <year>, Compiler
Explorer Authors` banner, using each file's **git creation year**
(added-at-this-path, so no `--follow` rename artifacts).
## Verification
- `check-license-headers` → clean (was 42 failures)
- `biome check` on all source → no fixes needed (banner format matches
existing convention)
- `tsc` backend + frontend + tests → clean
- pre-commit gauntlet (lint, ts-check, related tests: 528 passed) ran on
commit

Bumps the RazorForge compiler from `0.0.4-alpha` to the `0.1.0` release
(initial support added in #8825).
v0.1.0 is the first stable (non-`-alpha`) tag, so the install path drops
the `-alpha` suffix:
`/opt/compiler-explorer/razorforge-0.0.4-alpha/RazorForge` →
`/opt/compiler-explorer/razorforge-0.1.0/RazorForge`.
The matching install recipe is in compiler-explorer/infra#2192 (tarball
URL verified `200`).
Exposes mainline **gcc 14.4.0** and **15.3.0** (x86-64), plus their
assertions variants, in the **C** and **C++** compiler dropdowns.
### Why
This is the missing "expose in the UI" half of adding these gcc
versions. compiler-explorer/infra#2203 already *installs* them (the S3
artifacts are built), but without matching `.properties` entries they
don't appear in CE. cc @Yashinde145 — this is the companion PR to your
infra#2203; the version bump needs a change here too so the compilers
actually show up.
### What
Following the existing `g152`/`g143` pattern:
- `c++.amazon.properties`: `g144`, `g153` (+ `g144assert`, `g153assert`)
entries + added to `group.gcc86.compilers` /
`group.gcc86assert.compilers`.
- `c.amazon.properties`: the mirrored `cg144`, `cg153` (+ assertions)
entries + group lists (the shared gcc install serves both C and C++).
`test:props` passes (ran via the pre-commit hook). Only the C/C++
dropdowns are touched; other gcc-family languages (fortran/ada/d/…)
track gcc separately and could be extended in a follow-up if wanted.

This PR adds [CO2](https://github.com/hkalbasi/co2) which is a language
backward compatible with C, with some Rust interop features that
compiles to Rust's MIR.
I added two compiler `co2rustc` and `co2cc`, and a tool `co2miri` which
is Miri for CO2. I added `co2cc` under C compilers, to make it possible
to view diff of assembly for a C code compiled with CO2 and clang or
gcc. `co2cc` is a CO2 frontend which accepts gcc-like flags, and can (or
at least should) compile almost every ISO compatible C23 code.
`co2rustc` accepts Rust like flags, and added under a new `CO2`
language.
Tested locally and it seems to work.
I need some help in setting up artifacts (which, if I understand
correctly, needs to happen in `infra` or `compiler-workflows`). I make
an artifact `co2-multicall` in my CI, which needs to get symlinked in
`co2cc`, `co2rustc` and `co2miri`, and it needs to run a simple project
with miri to create the miri sysroot. If you show me a similar project,
I will do the job.
