Hi Roger and all, Please review the updated Webrev: http://cr.openjdk.java.net/~ntv/ramanand/8066982/webrev.02/
Bug: https://bugs.openjdk.java.net/browse/JDK-8066982 Roger, please see my comments about new tests: - All my test methods were earlier generic with main method and hence had private static qualifier. I have changed them now to match and to be consistent with the existing tests. Thank you for pointing this. - I agree with you on this. Particularly when we have tests around DST we can’t avoid timezone data. - I have defined dataProvider for every method and reduced the test data for cases where zone is not present(testWithoutZoneWithoutOffset() and testWithOffsetWithoutZone()). But for the other 2 cases where zone is present(testWithZoneWithOffset() and testWithZoneWithoutOffset()), I feel most of the data cases are necessary and some are required to be on safer side if in future the timezone rule changes. Also, this bug fix mainly affects these cases. I have created the dataProvider kepping in mind the below cases for 2 DST zones. 1. Time before overlap 2. Time during Overlap 3. Time after overlap 4. Valid Offsets for each of these times 5. Zero Offset for each time 6. Few Positive and negative invalid offsets for each time Regards, Ramanand. -----Original Message----- From: Roger Riggs Sent: Saturday, December 12, 2015 1:37 AM To: HYPERLINK "mailto:core-libs-dev@openjdk.java.net"; core-libs-dev@openjdk.java.net Cc: HYPERLINK "mailto:i18n-...@openjdk.java.net"; i18n-...@openjdk.java.net Subject: Re: <i18n dev> Review request for JDK-8066982: ZonedDateTime.parse() returns wrong ZoneOffset around DST fall transition Hi, Stephen, can you confirm that the added text and test in DateTimeFormatter is not a specification change? Our processes have a bit more to do if it is a spec change and it would limit the backport to JDK 8. This bug fix will cause an existing TCK/JCK test to fail but that is considered also a bug and is fixed. test/java/time/tck/java/time/TCKZonedDateTime.java Ramanand, some comments on the new test: - The 'private' qualifier on the tests and data providers is not used in the current tests and is not consistently present in the new one. Since it has little/no function, the tests would be a bit cleaner without it. - Typically, test that have data dependencies (such as the timezone data) cannot be used for compatibility to the specification, but the data is stable and it seems unavoidable in this case. - Are all of the data cases necessary to validate the specification? Redundant cases extend the testing time without adding more confidence to the quality.
