The 6 bytes obtained from `random_bytes()` is a 48-bit integer, which
cannot be converted to decimal on a 32-bit system, without being
implicitly cast to a float by PHP. This was causing problems with
setting the multicast bit, and it led to non-random node values.
This new approach splits the 6 bytes up into two 3-byte values, each a
24-bit integer, and applies the multicast bit to the most significant
bits before re-combining the bytes as a string.
If passthru() is disabled in php.ini, this will force the
SystemNodeProvider to return `false` for the node. Using the default
FallbackNodeProvider, ramsey/uuid will default to the
RandomNodeProvider, in these cases.
Closes#114
* Changes location of providers in the SystemNodeProviderTest
They are now grouped at the bottom of the class.
* Adds logic to SystemNodeProviderTest.
* Changes call to `file_get_contents` SystemNodeProvider so it can be
mocked.
* Changes SystemNodeProviderTest so native PHP functions are mocked
instead of the class under test.
* Changes SystemNodeProviderTest so "\n" is used instead of PHP_EOL
As the (input or output) of the tests is not system dependant it does
not make sense to use PHP_EOL. All of these instance have been
replaced for the sake of readability and stating intent more clearly.
* Adds dataprovider to SystemNodeProvider main test for input
variations.
* Adds OS to SystemNodeProviderTest dataprovider for Linux fail
scenario.
* Adds test for SystemNodeProvider to ensure invalid values are not
accepted.
* Changes names of dataproviders in SystemNodeProviderTest for
consistency.
* Changes SystemNodeProviderTest by grouping dataproviders together.
* Changes method in SystemNodeProviderTest to use the provided mock
functions.
* Fixes PSR-2 coding conventions in SystemNodeProviderTest.
* Minor change to SystemNodeProviderTest based on review.
Borrows the idea from cf1c981414 to
properly set the multicast bit to the "least significant bit of the
first octet of the node ID."
When merged, this will close#171 and #170
