php / pecl-system-dio Goto Github PK

Just built php_dio using manual here https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2
We need PHP 8.2 DLL here https://windows.php.net/downloads/pecl/releases/dio/0.2.1/ as almost year passed since 8.2 release date.
If it's take time to rebuild it manually please consider using Github automation https://github.com/cmb69/setup-php-sdk which can build multiple releases, including upcoming 8.3.

Hi, I've been testing out various IO options for an application that needs a very high IO throughput.
When testing the DIO functions, I keep getting an error saying I've run out of memory after calling dio_read() multiple times.

Test code
`<?php

#Create a 10KB file
file_put_contents(DIR.'/dio-test-file', str_repeat('0', 10 * 1024));

$hFile = dio_open(DIR.'/dio-test-file', O_RDONLY);
while(true){

#Go back to the start of the file
dio_seek($hFile, 0);

#Read some data
$data = dio_read($hFile, 10000);

}

?>`

I would expect the test code above to sit in the loop reading the first 10,000 bytes from the file over and over until the script is killed.
Instead, the script exits almost immediately with the following error
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 12288 bytes) in /dio-test.php on line 13

While there are source code directories for php5 and php7, there is none for php8, so the package cannot be build for recent PHP versions. If there are no plans to support this, it might be a good idea to add the info to package.xml, so users get clearer information why they won't be able to build.
