描述
Description
The following code:
<?php
echo '<pre>';
print_r(opcache_get_status());
Resulted in this output:
Array
(
[...]
[scripts] => Array
(
[/htdocs/temp.php] => Array
(
[full_path] => /htdocs/temp.php
[...]
)
But I expected this output instead:
Array
(
[...]
[scripts] => Array
(
[(chroot:/home/user1)/htdocs/temp.php] => Array
(
[full_path] => /htdocs/temp.php
[...]
)
[(chroot:/home/user2)/htdocs/temp.php] => Array
(
[full_path] => /htdocs/temp.php
[...]
)
When using opcache.validate_root=1, same paths across different chroot are listed as one file only. There should be multiple keys.
Prefix is hashed using the inode number, which is working fine (so it's not a collision bug!): https://github.com/php/php-src/blob/7f914620193079b42a91eb84451719e4b376702b/ext/opcache/ZendAccelerator.c#L2673
Also the https://github.com/amnuts/opcache-gui/ doesn't work on invalidating those specific files. Don't know if it's related, but it's possible.

调研方向
从引用的 ext/opcache/ZendAccelerator.c 位置开始,跟踪 opcache.validate_root=1 时 opcache_get_status() 如何构建 scripts 的键。使用完全相同的路径在不同的 chroot 中重现该示例,然后验证每个 chroot 都显示为一个独立的键,同时保留所示的 full_path。
