In an effort to reduce the number of warnings that building ICU emits, we should set the following define for ICU4C library code when building using MSVC/VisualStudio: _HAS_EXCEPTIONS=0
This tells the MSVC implementation of the STL that exceptions should not be used - which is fine for ICU4C library code, as the library code does not make use of exceptions at all.
- Use stack allocated UResouceBundle to reduce number of calls to malloc (in a method that can't report back an error if Out-Of-Memory [OOM] happens).
- Use LocalUResourcePointer for automatic clean-up of UResouceBundle.
- Use uprv_strdup instead of calloc + strcpy.
- Changes comments, formatting, etc.
* ICU-20104 Fix lazy init in Indian Calendar. Now matches other calendars.
* ICU-20104 export class IndianCalendar for testing.
* ICU-20104 shot-in-the-dark Windows build experiment.
* ICU-20104 fix memory leak in added test.
The ICU4C sample "date" program just uses the "default" ICU locale. This change lets you pass in an explicit locale argument for testing on platforms like Windows that don't have/use the environment variable "LC_ALL".
* ICU-20140 Allow duplicated keys in U-extension per RFC 6067
RFC 6067 [1] does allow duplicate keywords, but ICU4C's
uloc_forLanguageCode rejects it as invalid.
Change it to accept duplicate keywords and honor only the
1st one while ignoring subsequent ones per RFC 6067.
[1] Unicode extension to BCP 47:
https://tools.ietf.org/html/rfc6067
* ICU-20140 Add ICU4J test and tweak ICU4C test
ICU4J test diverges from ICU4C tests:
1. Handling of duplicate variants in ICU4J seem to be wrong:
https://unicode-org.atlassian.net/browse/ICU-20148
2. ULocale.forLanguageTag only throws NullPointException so
that ICU4C's test for duplicate attributes cannot be ported.
- Enable UWP version of ICU to use Environment variable ICU_ENABLE_TENTATIVE_ERA for testing placeholder era names.
- Use LocalArray<int32_t> for the Era Start Dates to simply memory management, so that goto can be removed.
- Also fix some minor typos in header file.
- Follow the spec to calculate the mimimum significant digits in engineering notation
- The bug is regression since ICU 58. The new test still passes on
ICU58-based DecimalFormat
- Maximum significant digits is not changed
> Clang comes with __has_declspec_attribute to detect whether the name of an attribute is implemented as a MS style __declspec.
> This adds __has_declspect_attribute to the list of clang compatibility macros and then uses that check to determine if __declspec(dllimport) and __declspec(dllexport) can be used.
