In the C++ break iterator code, change all use of NULL to nullptr.
This is in preparation for follow-on PRs to improve out-of-memory error handling
in Break Iterators, keeping use of nullptr consistent between old and new
or updated code.
- rewrite to semi modular code
- run the sections first, then get counts
- section counts in ToC, skip if empty
- many link improvements: linkify bugs and commits rather than separate lines
- new option, --commit-metadata= with path to metadata file
- new option, --fix-version=41 (used for SKIP sections)
- scaffolding for 'bad commits' list
- new module CommitMetadata with unit tests
- sample file format TEST_COMMIT_METADATA.md
- such commits are skipped
- refactored the commit skipping part (formerly used for cherry pick skips)
- add a report section for skipped commits
- add a cache for JIRA queries (for dev use): --cache-for-dev "/tmp/cldr-commit-cache" - optional
- add an 'excluded commits' section at the bottom
- make sure commit metadata is used to update ticket IDs and messages.
- Added code to use the parentLocales data in supplementalData.xml to determine the "parent locale ID" to use when
the requested resource bundle is not present (ICU-21126).
- Added code to change the parent-chain search path to handle the script better (ICU-21125; algorithm was described
in CLDR-15265):
- The base search patch is now ll_Ssss_RR -> ll_RR -> ll_Ssss -> ll -> root
- If the requested script is not the default script for the requested language and region, we automatically
avoid fallbacks that will implicitly change the script.
- Added new code to the CLDR-to-ICU data generation tool to generate source code, and used it to generate the lookup
tables for the new resource-fallback logic (we can't use the existing resource files for this, since that would
involve opening a resource bundle while trying to open another resource bundle). The data-generation stuff is
intended to be generic enough to allow for us to generate more static data tables in the future.
- Commented out a few collator tests, and changed one resource bundle test, because they're incompatible with the
new fallback logic (specifically, the default-script logic).
