Swoolew HTTP Server rejects Requests larger than over 2MB

[tux-rampage]

I created a simple setup to measure swooles I/O capacities: https://github.com/tux-rampage/swoole-io-test

During the tests I found out Swoole is always rejecting Requests larger than 2MB with the status code 413.

I guess this is related to #2373 (Which was a case I wanted to test in terms of memory consumption).

1. What did you do? If possible, provide a simple script for reproducing the error.

   • Sending a request with 1GB of data to a swoole webserver

2. What did you expect to see?

   • A 204 Response as defined in the handler

3. What did you see instead?

   • HTTP response 413 Request entity too large

4. What version of Swoole are you using (show your php --ri swoole)?

swoole

5. What is your machine environment used (including version of kernel & php & gcc) ?

   • Ubuntu 18.04

You can set the package_max_length option to increase the maximum length limit. But this takes more memory, because Swoole-HTTP-Server keeps all requested data in memory, not disk.

$http = new Swoole\Http\Server("127.0.0.1", 9501);
$http->set([
    'package_max_length' => 16 * 1024 * 1024,
])

@matyhtf but increasing body size from php.ini can also do the trick?

Or must be did in the way you provided?

If so, then how to clean the used memory by a file upload?
