            I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

            Your problem is that you have set SESSION_CONNECTION=session, but your SESSION_DRIVER=default, so you have to use SESSION_DRIVER=database in your .env. See the config/session.php:

            Is there an open source component that will subscribe to various database activity feeds and invalidate out of process caches like redis?
            Asked 2021-May-30 at 19:18

            We are looking to implement a redis based cache for read heavy data for fronting our database as a read through cache. I would like to implement a better invalidation mechanism than just TTL or LRU based eviction to prevent stale reads as much as possible.

            Several databases provide notification mechanism for database objects such as tables. For example oracle has Change Notifications and Postgresql has NOTIFY for this purpose. Is there any existing open source project/component that listens to these notifications and uses them to invalidate out of process caches like redis or memcached? I have seen several projects for doing this to in-process caches but none so far for out of process (either clustered/unclustered) caches.

            Redis Labs announced their new "RedisCDC" solution at RedisConf 2021 which seamlessly migrates data from heterogeneous data sources to Redis and Redis Modules. Its configurable and extendable, so you can easily create a custom stage that invalidates Redis keys when there is an update or delete on the source side.

            Okay, my problem is fixed. The Octavia-api node can't connect to amphorae-instance because they do not match the same network type (node - LAN and amphorae - VXLAN). So, I create a bridge interface at a node to convert vxlan for lan can connect (You can read here at step 7: create a network).

            In the deployment.py, you should wrap the 'debug_toolbar' string in a collection, for example a list, otherwise you will add one item per character to the INSTALLED_SETTINGS, and thus then you would load as apps 'd', 'e', 'b', etc.

            Everything in my code is running my database(Postgresql) is using utf8 encoding, I've checked the php.ini file its encoding is utf8, I tried debugging to see if it was any of the functions I used that were doing this, but nothing everything is running as expected, however after my frontend sends a post request to backend server through curl for some text to be inserted in the database, some characters like 'da' are converted to '?' in postgre and in memcached, I think php is converting them to Latin-1 again after the request reaches the other side for some reason becuase I use utf8_encode before the request and utf8_decode on the other side

            Don't replace " " with "%".

            Use urlencode and urldecode instead of utf8_encode and utf8_decode - It will give you a clean alphanumeric representation of any character to easily transport your data.

            If everything in your environment defaults to UTF-8, you shouldn't need utf_encode and utf_decode anyways, I guess. But if you still do, you could try combining both like this:

            when considering the only problem is connecting to socket io, your code should establish a bi directional connection between the client and the server, and it does.

            The 101 message means switching protocols

            so if you emit a message on event named test your server will catch it.

            the problem is in your client side, try any ready to use tools like this or anything else to independently test your socket io server

            Vulnerabilities

            memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free() that can result in data corruption and deadlocks due to items existing in hash table being reused from free list. This attack appear to be exploitable via network connectivity to the memcached service. This vulnerability appears to have been fixed in 1.4.37 and later.
            Memcached 1.6.x before 1.6.2 allows remote attackers to cause a denial of service (daemon crash) via a crafted binary protocol header to try_read_command_binary in memcached.c.
            The try_read_command function in memcached.c in memcached before 1.4.39 allows remote attackers to cause a denial of service (segmentation fault) via a request to add/set a key, which makes a comparison between signed and unsigned int and triggers a heap-based buffer over-read. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-8705.
            The process_stat function in (1) Memcached before 1.2.8 and (2) MemcacheDB 1.2.0 discloses (a) the contents of /proc/self/maps in response to a stats maps command and (b) memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain sensitive information such as the locations of memory regions, and defeat ASLR protection, by sending a command to the daemon's TCP port.

            Install memcached

            You can download it from GitHub.
