Feature/is expired#58 #59

What has been done

This pr introduces a new way to handle SessionContext. Now it is possible to do the following:

if (!$apiContext->isSessionActive()) {
    $apiContext->resetSession();
    $apiContext->save();
}

This way there is no saving an unchanged context.

Closes #58

DennisSnijder

Simple yet effective PR!
Nice one 😄

+    public function isExpired()


isExpired(): bool <- strict return type 😄

Aahhh good old strict type 😁 thx

Perhaps rename this function to something like isSessionExpired which makes this comment unnecessary.

🤔 Fair enough will make this change in all the SDK's then 👍

+        if (!is_null($this->sessionContext) && $this->isSessionExpired()) {


check for is_null($this->sessionContext) can go from here, because you do it in isSessionExpired already :)

If you follow my suggestion and change isSessionExpired to isSessionActive or hasActiveSession, Please do not forget to add an exclamation mark here (only reset if NOT has an active session :))

Mhmm AFAIK if we do this then if session is null it will run in an infinite loop resetting the session. At least that was my expiernce in Java 🤔 will double check to make sure.

Ah yea! The infinite loop:

Maximum function nesting level of '256' reached, aborting!

And it also fails because:

$timeExpiry = $this->sessionContext->getExpiryTime()->getTimestamp();

This will cause an error as of sessionContext is null! So therefore we need !is_null($this->sessionContext) in ensureSessionActive still 🤔. The null sessionContext will get handled higher up the code before a request is made.

Ah but then based on your suggestion below this can be fixed 👍

dnl-blkv · 2017-10-13T04:46:11Z

src/Context/ApiContext.php

-        if ($timeExpiry - time() < self::TIME_TO_SESSION_EXPIRY_MINIMUM_SECONDS) {
-            $this->resetSession();
-        }
+        return is_null($this->sessionContext) || $timeExpiry - time() < self::TIME_TO_SESSION_EXPIRY_MINIMUM_SECONDS;


Since you do is_null($this->sessionContext) check here, the method can be be opposite to what we've had and be called isSessionActive or hasActiveSession. This also fits well into our ensureSessionActive :)

Also, I'd go for an explanatory variable here. I missed it when initially built ensureSessionActive %).

So something like this:

if (is_null($this->sessionContext)) { return false; } else { $timeExpiry = $this->sessionContext->getExpiryTime()->getTimestamp(); $timeToExpiry = $timeExpiry - time(); return self::TIME_TO_SESSION_EXPIRY_MINIMUM_SECONDS < $timeToExpiry; }

For the changes in my review: let's have this one merged, and then distribute the approach over the other SDKs :)

OGKevin · 2017-10-13T11:19:19Z

@dnl-blkv As we discussed, this pr is not ready. Fixing the issue in client that is causing the infinite loop due to client also resetting session. This must be prevent for endpoints:session-server, device-server and installation.

Please make it an associative array:

const URLS_TO_NOT_ENSURE_ACTIVE_SESSION = [ self::INSTALLATION_URL => true,

+    const SESSION_SERVER_URL = "session-server";


Please use single quotes for the constants!

Also please post the URIS_NOT_REQUIRING_ACTIVE_SESSION right after the doc header, and the constants right after it :)

Java struggles 😁

+        if (!in_array($uri, self::URLS_TO_NOT_ENSURE_ACTIVE_SESSION, true)) {


Once you have an associative array instead of a list, you can use isset(self::URLS_TO_NOT_ENSURE_ACTIVE_SESSION[$uri])

Let's say URIS_NOT_REQUIRING_ACTIVE_SESSION for the sake of consistency :)
