Description

http://www.bigsoft.co.uk/blog/index.php/2014/12/08/posix-php-commands-not-working-under-centos-7

It looks like posix has been disabled in CentOS 7 due to a security hole. Not sure about the details there... Please consider removing posix commands.

After every single dep command, since 4.3.0, we are getting this error:

 [ERROR] Error: Call to undefined function Deployer\Util\posix_setsid() in

Installing php-process fixed this error, getting our security team to look at it. The information about security vulnerability in that library might be outdated...

[antonmedv]

Fixed, now there is a check:

if (extension_loaded('pcntl'))

If php-process is a hard dependency, it might be wise to include this in the composer.json.

[piotrantosik]

Error still exist, Fedora 27, Deployer 6.0.3

[Error] Call to undefined function Deployer\Utility\posix_setsid()

[antonmedv]

@piotrantosik try to install php-process ext. Also this is really strange as there check. Are you sure in version of dep?

[piotrantosik]

Thanks @antonmedv , after installing php-process works perfectly.

[xaoc2007]

Странная ошибка.
Почему бы не поставить проверку в код, есть ли в системе эта функция. и зачем вообще заставлять устанавливать расширение для php для сбора статистики на сервера Deployer-а, который вроде как отключен?

[antonmedv]

There is a check for this extension. Maybe this is some old vresions.

[fgibaux]

Hi,
The posix_setsid function is in the posix extension, not pcntl, so if you have only pcntl and not posix the error is raised.
I think the test should also include extension_loaded('posix')

[antonmedv]

Can you send pr?

[xaoc2007]

Дело не только в проверке на доступность расширения posix.
Зачем вообще этот код отрабатывает, если я отключил отсылку статистики? Или она не отключается через
set('allow_anonymous_stats', false);

?

[antonmedv]

You can disable it with set('allow_anonymous_stats', false);
