* bionic: Sort and cache hosts file data for fast lookupTom Marshall2016-08-044-0/+564
| | | | | | | | | | | | | | | | | The hosts file is normally searched linearly. This is very slow when the file is large. To mitigate this, read the hosts file and sort the entries in an in-memory cache. When an address is requested via gethostbyname or getaddrinfo, binary search the cache. In case where the cache is not available, return a suitable error code and fall back to the existing lookup code. This has been written to behave as much like the existing lookup code as possible. But note bionic and glibc differ in behavior for some corner cases. Choose the most standard compliant behavior for these where possible. Otherwise choose the behavior that seems most reasonable.

* Move tzdata scripts from bionic to external/icuNeil Fuller2016-07-182-454/+0
| | | | | | | | | | | | | | The scripts affect files in external/icu, bionic and the generated files affect libcore. The files must be updated together so there is no "obvious" home. OEM developers seem to want to update ICU themselves and have been asking how. Moving the scripts to external/icu and splitting the ICU generation code into a sub-script they can run makes some sense. Bug: 23419215 Change-Id: Ia26fa526fd2b560a79f36d327a10e262a85db752

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes affecting future time stamps America/Cayman will not observe daylight saving this year after all. Revert our guess that it would. (Thanks to Matt Johnson.) Asia/Chita switches from +0800 to +0900 on 2016-03-27 at 02:00. (Thanks to Alexander Krivenyshev.) Asia/Tehran now has DST predictions for the year 2038 and later, to be March 21 00:00 to September 21 00:00. This is likely better than predicting no DST, albeit off by a day every now and then. Changes affecting past and future time stamps America/Metlakatla switched from PST all year to AKST/AKDT on 2015-11-01 at 02:00. (Thanks to Steffen Thorsen.) America/Santa_Isabel has been removed, and replaced with a backward compatibility link to America/Tijuana. Its contents were apparently based on a misreading of Mexican legislation. Changes affecting past time stamps Asia/Karachi's two transition times in 2002 were off by a minute. (Thanks to Matt Johnson.) Bug: 26833368 Change-Id: I5af1d69f8ca767369f1cbc4aa863280b960777e0
* | bionic: Teach fnmatch(3) to handle UTF-8 characters in patternsTom Marshall2016-04-131-24/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is NOT comprehensive UTF-8 support. It is just a quick hack to make alternation work in bracket expressions so that the system file manager can find files with non-ASCII names in root mode. Bracket expressions that contain non-ASCII ranges are explicitly avoided to avoid the complexities of unicode collation rules. Things like the following will now work: fnmatch("те[с][т].jpg", "тест.jpg", 0); fnmatch("test[αβγ].txt", "testβ.txt", 0); Things like the following will still fail: fnmatch("тес[а-я].txt", "тест.txt", 0); Jira: CYNGNOS-2336 Change-Id: If38dc6692bc22d20128b0cd8a7632754a496d7fb

I ran stringbench[1] on ARM Juno, this optimization could outperform origin C implementation by 77%.

* | | | | Fix over read in strcpy/stpcpy/strcat.Christopher Ferris2015-10-294-148/+176

In these cases, the dest alignment code does a ldr which reads 4 bytes, and it will read past the end of the source. In most cases, this is probably benign, but if this crosses into a new page it could cause a crash. Fix the labels in the cortex-a9 strcat. Modify the overread test to vary the dst alignment to expost this bug. Also, shrink the strcat/strlcat overread cases since the dst alignment variation increases the runtime too much.

Add a 32 bit optimized cortex-a53 memcpy that is about ~20% faster on cached data. Fix the cortex-a15 __str{cat,cpy}_chk.S, memcpy_base.S to remove the phony functions, since they aren't needed any more. Then add a direct include of these for cortex-a53. Verified the new functions by stepping through all of the major paths and verifying the backtrace is still correct. Bug: 22696180 Change-Id: Iec92a3f82d51243cca76c9aff9f35d920ff865ae

Doing so via this hook has several advantages over patching the code in question: * The hacks do no pollute other repositories * The hacks do not have any risk of breaking any other devices * The hacks don't just live forever when we forget they exist * The hacks are all easy to find by locating them together When using this, please take extra care to include only the minimal code to support the change. Keep in mind that all code (and all libraries your code links against) will be part of the address space of every single process in the system!
