Update ICU (main branch and upcoming version 70) halfway to 2021b.
- with Samoa & Jordan rule updates
- with corrected pre-1993 transitions in Malawi (?), Portugal, etc.
- without for now (due to release timing) renaming Pacific/Enderbury to Pacific/Kanton
- without merging many zones whose timestamps agree since 1970
In this PR, I am updating the version number from 70.0.1 for the BRS task.
Previously, we had frontloaded part of this, so the diff in this PR are not as numerous.
It has also been decided that we should differentiate frontloaded tasks and RC tasks by having the version numbers being:
Frontload version number: XX.X.X (70.0.1 -> Major.minor.patch)
RC/GA version number: XX.X (70.1 -> Major.minor)
I've added some documentation for this, for future releases :)
Revise uses of UVector in rbtz.cpp to better handle memory allocation failures.
This is one of an ongoing series of commits to address similar problems with
UVector usage throughout ICU.
The changes include
- Use LocalPointers and UVector deleter functions to simplify OOM checking and recovery.
- Fix RuleBasedTimeZone::addTransitionRule(rule) to have standard ICU adopt behavior
when errors occur, meaning automatic deletion of the incoming rule. This simplifies
both the implementation of the function and the code at the call sites.
- Update addTransitionRule() call sites. Includes modifying the Dangi calendar initializtion
to not silently ignore errors.
- struct Transition is changed to derive from UMemory, which allows the use of LocalPointers.
- port of CLDR-14588
- use a fake Consumer<String>
- currently logs after each test class, not ideal but better
- Formerly ICU-12589 but that is not as related
- add unit test
Revise uses of UVector in basictz.cpp to better handle memory allocation failures.
This is one of an ongoing series of commits to address similar problems with
UVector usage throughout ICU.
The changes primarily involve switching to the use of LocalPointers for
the tracking of memory ownership, and to simplify cleanup in case of errors.
In the function BasicTimeZone::getTimeZoneRulesAfter(), also switched some additional
allocated memory to use LocalPointer or LocalMemory, for consistency in
memory handling.
