Upstream-Name: dart-sdk
Source: https://github.com/dart-lang/sdk
Comment: The Debian orig tarball is repacked from the upstream SDK checkout
 (an upstream gclient checkout of the 3.13.4 tag, whose third_party trees are
 pinned by upstream's DEPS file; see debian/README.source and
 debian/scripts/get-orig-source, which regenerates this tarball).
 .
 The Files-Excluded field below removes content that is either not
 distributable as source, not needed to build the SDK, or de-vendored in favour
 of the corresponding Debian system library. Nothing excluded here is
 referenced by the gn "create_sdk" target that this package builds:
 .
   * De-vendored to Debian system libraries: third_party/zlib and
     third_party/double-conversion. debian/rules substitutes a stub BUILD.gn
     that links the system copy (zlib1g-dev, libdouble-conversion-dev).
   * Toolchain and bootstrap directories: buildtools (the bundled clang, lld,
     gn, ninja and sysroot), tools/sdks (the bundled bootstrap Dart binary) and
     out. This package builds with the Debian system toolchain and bootstraps
     from a previous dart-sdk, so all of these are prebuilt binaries with no
     purpose here.
   * Prebuilt binaries shipped by upstream via CIPD, with no corresponding
     source in the tree: third_party/devtools/web (the DevTools web
     application, about 92 MB of compiled Flutter web output, CanvasKit
     WebAssembly and bundled fonts; upstream fetches it as a prebuilt CIPD
     bundle and this package does not ship it, see the patch making it
     optional; only the prebuilt web/ subdirectory is dropped, the
     devtools_shared Dart library beside it is source and is kept because
     pkg/dds is built from it),
     benchmarks/FfiBoringssl/native/out, benchmarks/FfiCall/native/out and
     benchmarks/NativeCall/native/out (prebuilt benchmark shared objects),
     third_party/d8, third_party/jsc and third_party/firefox_jsshell (prebuilt
     JavaScript engines used only by the upstream test runner), and
     third_party/gsutil (a prebuilt Python release-upload tool that also
     vendors its own unrelated dependency tree).
   * Test fixtures that consist of compiled artefacts: third_party/binaryen's
     test suite (about 35 MB, including prebuilt .wasm objects). Only the
     wasm-opt tool is built from third_party/binaryen; its test suite is not.
   * Prebuilt Java: the Gradle wrapper jars under the jni and jnigen example
     and Java directories, which are build accelerators for unrelated example
     projects.
   * Content that is not DFSG-free, or whose licensing cannot be reconciled:
     third_party/pkg/web, whose generated DOM bindings carry API documentation
     copied from MDN under CC-BY-SA 2.5 in 186 files; Debian treats the
     pre-3.0 Creative Commons licences as non-free. Nothing in the SDK build
     imports package:web -- the only occurrence of
     "import 'package:web/web.dart'" in the tree is inside a string literal in
     pkg/dartdev/lib/src/templates/web.dart, the template that
     "dart create -t web" writes out for the user.
   * Upstream code-generation inputs that the SDK build never reads:
     third_party/WebCore (Web IDL definitions, partly LGPL-2+ and BSD-2-clause)
     and third_party/mdn (browser compatibility data). Both are consumed only by
     tools/dom/scripts/dartdomgenerator.py and idlsync.py, which upstream runs by
     hand to regenerate dart:html; no gn target and no package refers to either.
   * Minified JavaScript with no corresponding source:
     third_party/pkg/dartdoc/lib/resources/highlight.pack.js, a minified build
     of Highlight.js 11.11.1 that upstream vendors without its sources. It is
     the only such file the binary package would have shipped. debian/rules
     also drops the <script> tag that referenced it from dartdoc's footer
     template, so `dart doc` output is self-consistent; the only effect is that
     generated API documentation is not syntax-highlighted.
 .
 What deliberately remains, for completeness: six small object and archive files
 (72 kB in total) under third_party/boringssl/src/util/ar/testdata. They are
 fixtures for BoringSSL's ar-parser unit test, and the C and C++ sources they
 were compiled from are in the same directory, at
 third_party/boringssl/src/util/ar/testdata/sample. After the exclusions above
 the source package contains no other object file, shared library, archive,
 WebAssembly module or jar.

Comment: These are the stock Autoconf helper scripts, shipped unmodified in
 essentially every autotools-using source package in Debian. The Autoconf
 exception is an *additional permission* under section 7 of the GPLv3: it
 allows the file to be distributed under the terms of the program whose
 configure script it serves, on top of the GPL-3+ grant. An additional
 permission can only widen what a recipient may do, so the result is strictly
 more permissive than GPL-3+ and is DFSG free. The full text of the exception
 is reproduced in the License paragraph below rather than referenced, so no
 lookup is needed to check it.

 Neither file is used when building this package: ICU is compiled here through
 gn, not through its autotools build, and they are retained only because they
 are part of the pristine upstream ICU source.

Copyright: 2014 the Dart project authors
License: BSD-3-clause
Comment: licensecheck reports the non-free "JSON" licence for this file because
 it defines the JSON-RPC 2.0 error-code constants and quotes the specification
 in its comments. The file's own header is the standard Dart BSD-3-clause
 notice and no JSON.org licensed code is present.

Copyright: 2012-2015 Google Inc, International Business Machines Corporation

License: BSD-3-clause
Comment: The file's own header explains that it began as Chromium data which
 included words from CC-CEDICT under a CC-SA licence, and that "all of
 CC-CEDICT unique words were removed from the data" precisely because CC-SA is
 incompatible with ICU's licence. What remains is the BSD-licensed Google data
 plus the Unicode terms. licensecheck reports "CC-SA" for this file because the
 explanation mentions it, not because any CC-SA content is present.

Comment: The Wikipedia sample text used by the grapheme-cluster tests. It is
 not only in the Wikipedia/ directory: test/src/text_samples.dart embeds the
 same text inline as Dart string constants and says so in its own doc comment,
 so it carries the Creative Commons licence rather than the 3-clause BSD of the
 Dart sources around it. CC-BY-SA-3.0 is DFSG free; the 2.x versions are not.
