#703 Unable to open concurrent tabs

[Chirag Bansal]

When a long query is running in one tab, I am unable to open another tab of adminer.

System config:
Apache/2.4.29 (Ubuntu)
PHP 7.2.19 (default config)
adminer 4.7.2
mysql 5.7 / pgsql 10

I checked and this seems to be happening due to php session locks. The php session is locked while the query is running.

Adminer stops session once it doesn't need it (e.g. before executing SQL commands) but it doesn't work for some reason. I can reproduce at demo.adminer.org.

The problem seems to be that ini_set("session.use_cookies", false) fails after starting a session in recent PHP versions.

It happens since PHP 7.2.0: https://github.com/php/php-src/blob/php-7.2.0/ext/session/session.c#L712
