random: Use branchless implementation for mask generation in Randomizer::getBytesFromString() (#10522) * random: Add `max_offset` local to Randomizer::getBytesFromString() * random: Use branchless implementation for mask generation in Randomizer::getBytesFromString() This was benchmarked against clzl with a standalone script with random inputs and is slightly faster. clzl requires an additional branch to handle the source_length = 1 / max_offset = 0 case. * Improve comment for masking in Randomizer::getBytesFromString()

random: Fix off-by-one in fast path selection of Randomizer::getBytesFromString() (#10449) With a single byte we can choose offsets between 0x00 and 0xff, thus 0x100 different offsets. We only need to use the slow path for sources of more than 0x100 bytes. The previous version was correct with regard to the output expectations, it was just slower than necessary. Better fix this now while we still can before being bound by our BC guarantees with regard to emitted sequences. This also adds a test to verify the behavior: For powers of two we never reject any values during rejection sampling, we just need to mask off the unneeded bits. Thus we can specifically verify that the number of calls to the engine match the expected amount. We also verify that all the possible values are emitted to make sure the masking does not remove any required bits. For inputs longer than 0x100 bytes we need trust the `range()` implementation to be unbiased, but still verify the number of engine calls and perform a basic output check.

random: Randomizer::getFloat(): Fix check for empty open intervals (#10185) * random: Randomizer::getFloat(): Fix check for empty open intervals The check for invalid parameters for the IntervalBoundary::OpenOpen variant was not correct: If two consecutive doubles are passed as parameters, the resulting interval is empty, resulting in an uint64 underflow in the γ-section implementation. Instead of checking whether `$min < $max`, we must check that there is at least one more double between `$min` and `$max`, i.e. it must hold that: nextafter($min, $max) != $max Instead of duplicating the comparatively complicated and expensive `nextafter` logic for a rare error case we instead return `NAN` from the γ-section implementation when the parameters result in an empty interval and thus underflow. This allows us to reliably detect this specific error case *after* the fact, but without modifying the engine state. It also provides reliable error reporting for other internal functions that might use the γ-section implementation. * random: γ-section: Also check that that min is smaller than max This extends the empty-interval check in the γ-section implementation with a check that min is actually the smaller of the two parameters. * random: Use PHP_FLOAT_EPSILON in getFloat_error.phpt Co-authored-by: Christoph M.

Fix pre-PHP 8.2 compatibility for php_mt_rand_range() with MT_RAND_PHP (#9839) * Fix pre-PHP 8.2 compatibility for php_mt_rand_range() with MT_RAND_PHP As some left-over comments indicated: > Legacy mode deliberately not inside php_mt_rand_range() > to prevent other functions being affected The broken scaler was only used for `php_mt_rand_common()`, not `php_mt_rand_range()`. The former is only used for `mt_rand()`, whereas the latter is used for `array_rand()` and others. With the refactoring for the introduction of ext/random `php_mt_rand_common()` and `php_mt_rand_range()` were accidentally unified, thus introducing a behavioral change that was reported in FakerPHP/Faker#528. This commit moves the checks for `MT_RAND_PHP` from the general-purpose `range()` function back into `php_mt_rand_common()` and also into `Randomizer::getInt()` for drop-in compatibility with `mt_rand()`. * [ci skip] NEWS for `MT_RAND_PHP` compatibility

Clean up nested exceptions without value-add in ext/random (#9211) * Remove exception in Randomizer::shuffleBytes() The only way that `php_binary_string_shuffle` fails is when the engine itself fails. With the currently available list of engines we have: - Mt19937 : Infallible. - PcgOneseq128XslRr64: Infallible. - Xoshiro256StarStar : Infallible. - Secure : Practically infallible on modern systems. Exception messages were cleaned up in GH-9169. - User : Error when returning an empty string. Error when seriously biased (range() fails). And whatever Throwable the userland developer decides to use. So the existing engines are either infallible or throw an Exception/Error with a high quality message themselves, making this exception not a value-add and possibly confusing. * Remove exception in Randomizer::shuffleArray() Same reasoning as in the previous commit applies. * Remove exception in Randomizer::getInt() Same reasoning as in the previous commit applies. * Remove exception in Randomizer::nextInt() Same reasoning as in the previous commit applies, except that it won't throw on a seriously biased user engine, as `range()` is not used. * Remove exception in Randomizer::getBytes() Same reasoning as in the previous commit applies. * Remove exception in Mt19937::generate() This implementation is shared across all native engines. Thus the same reasoning as the previous commits applies, except that the User engine does not use this method. Thus is only applicable to the Secure engine, which is the only fallible native engine. * [ci skip] Add cleanup of Randomizer exceptions to NEWS
