This could happen when the handler is depending on a PHP extension, or connection to a database fails, or any other circumstance that may trigger an exception in the constructor of the session handler itself. We should be aware of this when using the session handler, therefore we update the phpdoc here to reflect that.

Add support for RFC6265bis SameSite cookie attribute

Fixes for the remainder of lib/SimpleSAML

All descendants overload this function anyway

Historically, SimpleSAML_SessionHandler::newSessionId() has also created the session, sending the cookies to the browser. This is problematic both because given the name of the method one would not assume such behaviour, and also because even for transient sessions the handler would then try to set cookies. When we are using a transient session, it is likely to be because we cannot set cookies or because there was a temporary error when loading the session. If we try to set the cookies even for transient sessions, we could either get an error because cookies cannot be set, or overwrite the previous session cookies with transient ones, trashing a legitimate session in case a temporary error occurs.

As a side effect, this can also cause behaviours like the one described in issue #413. There's no point in trying to set the cookies when it's not possible, so we shouldn't even try, and save us the errors.

To fix this, we made SimpleSAML_SessionHandler::setCookie() abstract, forcing each extending class to implement it. The former implementation is moved to SimpleSAML_SessionHandlerCookie, and the SimpleSAML_SessionHandlerPHP gets a new method that starts the session, effectively sending the cookie. SimpleSAML_Session would then be responsible to call the setCookie() method of the session handler when creating a regular session, and skip it when creating a transient one. This introduces a bug, since SimpleSAML_Session was trying to set the auth token cookie calling the same setCookie() method in the session handler. We fixed that by using SimpleSAML\Utils\HTTP::setCookie() instead, in 8756835b.

This resolves #413.

Add a method to SimpleSAMLphp_SessionHandlerPHP to restore a session existing previously to our own session. This can be used in SimpleSAML_Session to restore the PHP session status previous to calling our API, while also guaranteeing that our session is correctly saved. The documentation has been updated to reflect this and recommend how to deal with conflicting PHP sessions. This closes #244 and resolves #349.

Move SimpleSAML_Utilities:: setCookie() to SimpleSAML\Utils\HTTP:: setCookie() and deprecate the former.

Since 5.2.0 is now the minimum supported version, this check is no longer
necessary.

Adds options to control the various session cookie parameters, and
changes users of setcookie to use those options instead.
