Description:

I just changed my default cache driver to octane and i got the following error:

unserialize(): Error at offset 10000 of 10000 bytes#0 [internal function]: Illuminate\Foundation\Bootstrap\HandleExceptions->handleError()

Looks like it have problem with Eloquent\Collection, if the data is big, it cannot cache it:

Cache::store('octane')->rememberForever('key', fn() => Thread::query()->latest()->take(100)->get());

The Octane cache is based on a Swoole Table, in case you are using the Swoole server. The cache is limited to 1000 rows with 10.000 bytes each by default:

octane/config/octane.php

Lines 125 to 139 in 9faedfb

	/*
	|--------------------------------------------------------------------------
	| Octane Cache Table
	|--------------------------------------------------------------------------
	|
	| While using Swoole, you may leverage the Octane cache, which is powered
	| by a Swoole table. You may set the maximum number of rows as well as
	| the number of bytes per row using the configuration options below.
	|
	*/
	'cache' => [
	'rows' => 1000,
	'bytes' => 10000,
	],

For larger items, you might want to:

• consider using a different type of cache
• increase the default size of the Octane cache per item
• define and use a separate Swoole Table for the larger items

I suspect your initial exception occured because the data was truncated during insert.

I have the same problem, how can I fix it ?, I tried to increase the bytes and row but it doesn't work.

This is an issue that needs to be worked around. You can set an entry to the swoole table that is larger the it can contain and we don't get a false back from $this->table->set() in the put method. It thinks it added it correctly. This would probably be something that swoole needs to address.

The problem on the octane side is that we are failing to handle the unserialize error on the get method. The data is corrupted, it should be handled in some way. Report the error (maybe a more friendly message...) and return null as if the record was not found would seem like a logical workaround for the get method.

            try {
                return unserialize($record['value']);
            } catch (Throwable $e) {
                report($e);
                return null;
            }

This will be fixed on the next release, next week.
