* | Implement zip64 support for ZipFile/ZipInputStream/ZipOutputStream.Narayan Kamath2015-02-271-0/+59
|/ | | | | | | | | | | | | | | | | | There are several open questions that I hope to resolve in future changes : - Our heuristics for detecting whether a zip outputstream should switch over to zip64 or not are imprecise. - Also, given that we now officially support zip64, we have to assume new entries whose size is unknown need the zip64 header / footer. This will make output files slightly larger and less compatible with older tools. If we don't do this, we'll have to go back and rewrite & compact parts of the stream we'd already flushed, which isn't always possible. The other option is to assume zip32 for streams of unknown length and throw if more than 4G of data is written to them. Change-Id: Ibb4a97b5f83fd3ab850d7c407ecfda663968a6b9

* Fix ZoneInfo.useDaylightTime()Neil Fuller2014-09-151-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently implemented is "are there any offset transitions in the future?". This is wrong: Transitions may occur in the future because of DST, but can also occur for other reasons (e.g. if the raw offset for a zone changes). We should be implementing: Is the currently active transition, or any transition in the future, one that has isDst == true. This was causing a test failure in libcore.java.util.TimeZoneTest#testDisplayNames for Asia/Novokuznetsk and Europe/Simferopol for tzdata2014g. This is because they have a transition entry for October 26, 2014 (i.e. in the future). For each, the existance of the transition entry is not due to an offset change at all: For Asia/Novokuznetsk it is because the abbreviation for the zone changes on that date (information we don't curently use). For Europe/Simferopol it is because the offset from UTC changes on that date (but there is no actual DST transtion).

* Fix TimeZone.getAvailableIDs(int).Elliott Hughes2014-08-111-8/+24
| | | | | | | | | | | | | This was broken by the removal of the pre-computed raw offsets from the tzdata file. I think that's still the direction we want to go (with us hopefully using more of icu4j at some point, and eventually relying solely on the icu time zone data), so this patch adds code to lazily evaluate all the offsets by instantiating all the time zones.

* | Add a cache for ZoneInfo objects in JavaNeil Fuller2014-07-162-12/+35
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mirrors the single-item cache in localtime.c. This is in preparation for an upcoming change to migrate android.format.text.Time over to Java. It will be making use of the Java ZoneInfo instead of the native equivalent. The Java cache has a size of 1 like the bionic one, though this can easily be increased. Given the default TimeZone / ZoneInfo was always pinned, in many cases the memory usage will not go up noticeably. In scenarios where applications load timezones besides the default a cache size of 1 potentially increases pinned memory usage by one ZoneInfo plus the overhead of the prototype object held by the cache (which is never returned to callers). An example ZoneInfo is "Europe/London", which has ~190 transitions (1 int + 1 byte) and ~6 types (1 int + 1 byte). Overhead of other fields is ~ 13 bytes, plus the ID string. 190 * (4 + 1) + 6 * (4 + 1) + 13 = 993 bytes. The prototypes held by the cache share the majority of their memory with their clones returned from ZoneInfo.makeTimeZone() and so the overhead of introducing the cache itself should be in the order of a few tens of bytes at most. In future we may want to increase the cache size to 2 in order to support apps that compare / switch timezones to increase the odds of the default remaining in the cache. Sizes above 2 look increasingly specialist. Change-Id: I0b7daa8ad5d334c8d421dfaa6e0421d3c181a915

* Fix TimeZone's handling of Australia/Lord_Howe.Elliott Hughes2012-07-302-23/+34
| | | | | | | | | | | | | | | | | | Australia/Lord_Howe has a half hour difference between standard and daylight time, rather than the usual hour. Our ZoneInfo implementation ignored this. Fix that oversight, make SimpleDateFormat actually use this information, and prevent TimeZone.getTimeZone("GMT") and TimeZone.getTimeZone("UTC") from being quite as expensive as they accidentally were. Longer term I think we should probably remove all uses of getDSTSavings from libcore in favor of TimeZone.getOffset, but this is probably a useful step forwards anyway. It fixes Australia/Lord_Howe in the meantime and it means that anyone else who's using getDSTSavings won't be bitten (even if they too really ought to be using TimeZone.getOffset).
