Bug #76484 [Fbk->Opn]: emory leakage with CURLOPT_SSL_VERIFYPEER set to TRUE

Edit report at https://bugs.php.net/bug.php?id=76484&edit=1 ID: 76484 User updated by: john357smith at gmail dot com Reported by: john357smith at gmail dot com Summary: emory leakage with CURLOPT_SSL_VERIFYPEER set to TRUE -Status: Feedback +Status: Open Type: Bug Package: cURL related Operating System: Linux PHP Version: 7.2.6 Block user comment: N Private report: N New Comment: Hi again Sorry for the late answer I didn't get any email notification about your replay. I tried it again with the latest version 7.2.9 compiled with only necessary options. After one hour the memory_get_usage() reports still the same number but consumed virtual memory increased from 290MB to 420MB. Couldn't be problem with leakage in openssl or curl library? I'm using openssl-1.0.2k-8 and curl-7.29.0-42. Here are screenshots with running process and htop showing memory usage: https://imgur.com/upfRDl0 - after start https://imgur.com/kpCUsbV - after 1 hour Thanks.

No leaks. If you var_dump(memory_get_usage()) do you see an increase after a few requests, or does it actually take on the scale of an hour to see it? What does valgrind have to say? ------------------------------------------------------------------------ [2018-07-25 18:48:14] john357smith at gmail dot com One month after I created this bug and no feedback? Will somebody look at it? ------------------------------------------------------------------------ [2018-06-15 16:57:56] john357smith at gmail dot com Description: ------------ When cURL is used with CURLOPT_SSL_VERIFYPEER set to TRUE or even without setting it (= default value is TRUE) there is a memory leakage with every call causing memory usage of php process to be constantly increasing. memory_get_usage() reports still the same value so it must be core problem. Keep test script running for more than 1 hour to see difference in memory usage (e.g. with top/htop etc.) After running this script for 24 hours I got 50% of system memory to be used (cca 2GB)! Test script: --------------- error_reporting((E_ALL)); while (TRUE) { $url = "https://www.yahoo.com/"; echo("Fetching $url ... \n"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_NOBODY, TRUE); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE); curl_exec($ch); curl_close($ch); usleep(200000); } Expected result: ---------------- No memory leakage even when script is running forever. Actual result: -------------- Memory usage is constantly increasing in time. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76484&edit=1
