* Add byte-based units to CLDR dataEdward Welbourne2017-06-132-555/+610
| | | | | | | | | | | | Scan CLDR for {,kilo,mega,giga,tera,peta,exa}byte forms and their IEC equivalents, providing SI and IEC defaults when missing (which all of IEC are) in addition to the usual numeric data. Extrapolate from any present data (e.g. French's ko, Mo, Go, To imply Po, Eo and, for IEC, Kio, Mio, etc.), since CLDR only goes up to tera. Propagate this data to QLocale's database ready for use by QLocale::formattedDataSize(). Change-Id: Ie6ee978948c68be9f71ab784a128cbfae3d80ee1 Reviewed-by: Shawn Rutledge <shawn.rutledge@qt.io>

* Tidy implementation and use of QDateTimeParser::setDigit()Edward Welbourne2017-06-131-11/+11
| | | | | | | | | | | | | | | The implementation did a validity check on data it then gave to constructors that repeat the validity checks; so do the construction first and use the cheaper instance isValid() methods instead. Fixed local callers (but not QDateTimeEditPrivate::stepBy, the only other caller) to actually attend to the return value; if the attempt to set a field fails, it probably means the min is too low, or max too high; and comparing the modified date-time against global min and max makes no sense if it hasn't been revised anyway.

* QRandomGenerator: mix the Linux AT_RANDOM random bytes in the fallbackThiago Macieira2017-06-121-3/+26
| | | | | | | | | | | | | | | | | | The Linux kernel gives us 16 bytes of random data and sets a pointer to it in the ELF AuxV (the same one that allows us to get HWCAP on ARM systems). So if we end up in the fallback generator, at leat we'll get a good amount of entropy to seed the Mersenne Twister. This could happen if the application is run in a chroot(2) or container without /dev/random or /dev/urandom. That is probably an installation mistake, so we don't optimize this case for performance. With this commit, we have now good, high-quality fallbacks for Windows (rand_s), for BSDs (arc4random) and for Linux. The only missing, supported OS without a good entropy source is QNX.

* QRandomGenerator: improve the fallback seeding in emergenciesThiago Macieira2017-06-121-1/+31
| | | | | | | | | | | | | | | | If we've never read any samples from hardware RNG or from /dev/urandom, then there are no stored samples for us to seed the Mersenne Twister. In that case, attempt to obtain an emergency sample that consists of some random bits from the variable addresses (ASLR should help) and from the clock (using nanosecond quality, instead of seconds). There's still the possibility that we'll get poor entropy: very close to boot, if the kernel entropy pool is empty, ASLR could be poor and the monotonic clock value could be consistent from boot to boot. There's nothing we can do about that. Change-Id: Ia3e896da908f42939148fffd14c5b0c7b608371b Reviewed-by: Lars Knoll <lars.knoll@qt.io>

| | | | | | | | | | | This commit adds support for the x86 RDRAND instruction for QRandomGenerator. This is the same that libstdc++-v3 uses for std::random_device() by default. If it fails because the hardware does not have enough entropy collected, we fall back to the operating system generator, which often has more entropy collected from other sources.

* QTemporaryFile: fix the generation of names from templatesThiago Macieira2017-06-121-2/+5
| | | | | | | | | | | | | | | | First and most importantly, let's not use more than half of the template for the application's PID. With over 71% of all PIDs on a typical Linux system and 90% of those on a Darwin system having 5 decimal digits, using them all in a template that is usually 6 characters long is wasteful. That leaves only 1 character for the random part, thereby reducing the number of temporary files possible to only 52. So limit the PID to half the characters of the template. Second, let's use QRandomGenerator::bounded to create the the random part, instead of qrand (which is often unseeded at this point).

* Long live QRandomGeneratorThiago Macieira2017-06-125-4/+968
| | | | | | | | | | | | | | | | | | | This class provides a reasonably-secure random number generator that does not need seeding. That is quite unlike qrand(), which requires a seed and is low-quality (definitely not secure). This class is also like std::random_device, but better. It provides an operator() like std::random_device, but unlike that, it also provides a way to fill a buffer with random data, not just one 32-bit quantity. It's also stateless. Finally, it also implements std::seed_seq-like generate(). It obeys the standard requirement of the range (32-bit) but not that of the algorithm (if you wanted that, you'd use std::seed_seq itself). Instead, generate() fills with pure random data. Change-Id: Icd0e0d4b27cb4e5eb892fffd14b4e3ba9ea04da8 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

Use the same format for the (common part of the) all-zeros line. Document and lay-out headers and format string, to make them easier to keep in sync. Make a pair of comments clearer. Re-ran the script to regenerate the table: the result is best viewed with git show -w, to ignore the spacing changes (or git show -b to notice only the one harmless discrepancy exposed in old all-zeros data). Aside from spacing, locale_data[] has gained some missing columns in its header comment, which now lines headings up properly above actual data.

This avoids having to create a QString from QStringRefs every time an entity is looked up. Only costs 280B in text size on optimized GCC 6.1 Linux AMD64 builds.
