Description
Currently the random_compat library included with WordPress core is the only part that fails against PHP 7 linting. As a tech at WP Engine I've noticed that our customers run into problems when pushing to their remote repositories, so I did a bit of investigation and it looks like the external library included was updated to correct this as of October 2016 as commented here: https://core.trac.wordpress.org/ticket/35665#comment:6
I've created the attached diff and it passes all of the unit tests included with core. I've also verified that it lints correctly via the following command.
for file in $(find . -type f -name "*.php"); do php -l $file; done | grep -v "No syntax errors"
#35665 - Previously updated to version 1.2.1 in ticket #35665

Diffing the versions in github looks sane, as does this patch.
It's always been expected that these files would not parse under PHP7, as they're not loaded there. Unfortunately it seems that WPEngine blocks deploying these files, causing issues (IMHO, it's WPE's responsibility to allow them to be deployed).
While I have no issue updating these, as we're so close to the 4.9 release, I'm tempted to leave it until 4.9.1 or 5.0 - even though I don't expect it'll cause any breakage.

- Milestone changed from Awaiting Review to 4.9.1
Okay, lets get this in 4.9.1 - I'll review once 4.9 is out. At the minimum we'll remove the PHP7 parse errors from 4.9.1 if the changes upstream are larger than expected.

Did a scan to see who was using this. Doesn't look (to me) like anything SHOULD break.

I'm a plugin author mentioned in the post above.
So does upgrading this library affect us at all, do we have to make any changes?

Plugins calling random_int() and random_bytes() should be fine with the changes made here, I'm not really sure why the plugins list was posted :)
Something I am going to note here, is that [42130] Updated Random_Compat from 1.2.1 to 2.0.11, which in the process dropped the OpenSSL provider for WordPress 5.0.
It's possible that the loss of OpenSSL here could be an issue for some environments, notably locked down linux environments and older Windows systems off the top of my head.
I'm contemplating if we shouldn't add the OpenSSL Handler back in, it'll mean we diverge from upstream, but might be the safest option overall for WordPress.

@dd32 It was asked in Slack to see who was using it and if they'd have issues. As I said, I don't think anyone will have issues but listing them was no work for me after the scan so I figured I'd share.

Ah cool, no problem either way :)

@dd32 - The risk for breakage should be very minimal, but I would add a recommendation in the 4.9.2 release notes in case it does happen.
If a plugin breaks with this upgrade:
- Replace
random_int()withwp_rand() - Replace
random_bytes()with a function that useswp_rand()to construct a string.
For example:
<?php
/**
* Alternative to random_bytes() that uses wp_rand().
*
* @param int $len
* @return string
* @throws Exception
* @throws TypeError
*/
function wp_random_byte_string($len = 0)
{
if (!is_int($len)) {
throw new TypeError("Length must be an integer.");
}
if ($len < 1) {
throw new Exception("Length must be greater than 0");
}
$chr = '';
for ($i = 0; $i < $len; ++$i) {
// pack('C', $int) is equivalent to chr($int), without cache timing leaks
// See: https://paragonie.com/blog/2017/02/cryptographically-secure-php-development#chr
$chr .= pack('C', wp_rand(0, 255));
}
return $chr;
}
This will allow you gracefully handle degradation. (Feel free to adapt this sample function for core if you want.)

We've not updated the library in 4.9.2, instead I've modified the old version to parse correctly.
It's likely I'll hack the OpenSSL variant back in to be on the safe side as I'm not going to attempt to setup one of these old windows servers.
