Bug #79559 [NEW]: TLS connections timing-out on 7.4 (all versions after 7.3.17)

From: imnieves at gmail dot com Operating system: Linux PHP version: 7.4.5 Package: *Encryption and hash functions Bug Type: Bug Bug description:TLS connections timing-out on 7.4 (all versions after 7.3.17) Description: ------------ Several users of phpredis (a PHP interface to Redis) have noticed (in php from 7.4.0 and onwards) that TLS connections to Redis time out. When we establish non-TLS connections to Redis (using the same phpredis), we experience no timeout. I have personally verified the issue exists on all versions of 7.4 from 7.4.0 to 7.4.5, and that the issue does not exists on version 7.3.17 Test script: --------------- The test script is longer than 20 lines, so here is a link: https://github.com/phpredis/phpredis/issues/1726 Here you can find the script, its output, log trace, and explanation of test setup. Expected result: ---------------- The expectation is that TLS connections are either established or not in a consistent amount of time, but not seemingly randomly timing out (taking a large amount of time to fail). Actual result: -------------- The actual result is that TLS connections are being established in an inconsistent amount of time. -- Edit bug report at https://bugs.php.net/bug.php?id=79559&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79559&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79559&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79559&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79559&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79559&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79559&r=support Expected behavior: https://bugs.php.net/fix.php?id=79559&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79559&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79559&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79559&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79559&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79559&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79559&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79559&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79559&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79559&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79559&r=mysqlcfg
