Review: dart-characters 1.4.1-1

Package Information

DescriptionString operations that are Unicode grapheme cluster aware

This package ships the characters Dart library as sources so that other Dart packages can depend on it at build time.

Strings are sequences of Unicode code points, but the characters a user perceives are grapheme clusters. This library splits strings into those clusters and iterates over them.

DFSG NEW review for dart-characters version 1.4.1-1

Summary

  • Licensing is DFSG-compliant and debian/copyright is accurate: Yes
  • Packaging is of good quality: Yes
  • Issues: 0 blocker, 0 important, 0 minor
  • debian/watch: version 5
  • debian/copyright: machine-readable
  • Scan before the review: nothing found

Licensing

The source is DFSG-free. debian/copyright is machine-readable (DEP-5, copyright-format 1.0) and its Files: stanzas accurately cover the tree: the Dart project sources under BSD-3-clause, the Unicode Consortium data files and the generated code derived from them under the Unicode License V3, and the Wikipedia Hangul sample under CC-BY-SA-3.0. All licence texts that are not in /usr/share/common-licenses are reproduced in full, and the licences combined in the installed sources are compatible.

Packaging

Packaging is clean and minimal: a single Architecture: all source-shipping binary package, built with debhelper compat 14 and dh-sequence-single-binary, Standards-Version 4.7.4 (current Policy is 4.7.4.1), correct Vcs-* and upstream metadata, a working autopkgtest smoke test, and a reproducible-build timestamp fix in rules. No policy violations or upgrade concerns found.

Issues

None.

Verified ◂
  • Prescan holder 'Unicode®, Inc. / Unicode and the Unicode Logo are registered trademarks of Unicode, Inc.' appears in the UCD header of third_party/Unicode_Consortium/{DerivedCoreProperties.txt, GraphemeBreakProperty.txt, GraphemeBreakTest.txt, emoji_data.txt, emoji_test.txt}; the holder 'Unicode, Inc.' is already named in the Files: third_party/Unicode_Consortium/* stanza (Copyright: 1991-2024, Unicode, Inc.), so nothing is missing.
  • Generated code lib/src/grapheme_clusters/table.dart and test/src/unicode_grapheme_tests.dart are produced by the generators shipped in tool/ (tool/bin/generate_tables.dart, tool/bin/generate_tests.dart) from the third_party/Unicode_Consortium data files, so their preferred form (generator input) is present; their dual BSD-3-clause and Unicode-3.0 stanza matches the file headers.
  • The Hangul sample in test/src/text_samples.dart is sourced from third_party/Wikipedia/hangul.txt (Korean Wikipedia) and is correctly dual-licensed BSD-3-clause and CC-BY-SA-3.0 in its own stanza.
  • All Dart source files (lib/, test/, benchmark/, example/, tool/) carry 'Copyright (c) , the Dart project authors' BSD-style notices matching the Files: * stanza; minor year drift (2018/2020/2023/2024 vs 2019) is immaterial.
  • /usr/share/common-licenses/CC-BY-SA-3.0 exists, so the pointer in the CC-BY-SA-3.0 licence stanza is valid.
  • uscan found the packaged version as the newest upstream release (upstream 1.4.1, packaged 1.4.1).
  • Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (CC-BY-SA-3.0).
Not confirmed ◂

None.

Proposed changes ◂

None.
