What happened?

Hello friends, the process of searching for missing files in my project is ongoing and doesn't stop. I have updated Composer, but the issue remains unresolved.

Steps to Reproduce

When I enter the command "strace -tt -T -p pid_id" via SSH, I can see the errors.

Expected Output

bug fix.

Anything else?

[kenjis]

Cannot reproduce.

[mettleshade]

It appears to be happening when the website's traffic is increasing. Currently, all processors are at 100%.

Cannot reproduce.

Ah, it is probably not a bug.

If you write code like helper('foo'),
CI4 searches for the helper file foo_helper.php in all namespaces by default.

Helpers will be automatically discovered within defined namespaces when using the helper() function, as long as it is within the namespaces Helpers directory:
https://codeigniter4.github.io/CodeIgniter4/general/modules.html#helpers

Specify Composer packages to search:
https://codeigniter4.github.io/CodeIgniter4/general/modules.html#specify-composer-packages
or if you want to load single helper file, specify the namespace:
https://codeigniter4.github.io/CodeIgniter4/general/helpers.html#loading-from-non-standard-locations

Thank you! Can we specify exact locations for our own helpers in the system, for example: app/Helpers/test_helper.php? I couldn't find it in the documentation.

[mettleshade]

After uploading the file, does keep search!

Does it upload the files again every time the user enters the site?

[kenjis]

@mettleshade What did you upload? and what do you want?
It seems scanning for unrelated composer package namespaces is gone.

[kenjis]

Can we specify exact locations for our own helpers in the system, for example: app/Helpers/test_helper.php?

helper('App\test');
// or
helper('App\Helpers\test');

But the following would be faster.

require APPPATH . 'Helpers/test_helper.php';

Thank you. I have disabled Composer Packages and Auto-Discovery, but there hasn't been a significant improvement in performance. I'm considering making performance-enhancing changes, and if I do, I'll let you know.

[kenjis]

Thank you for the info. Checking for non-existent helpers, etc. is useless, but does not seem to have a significant impact on performance.

It seems your server is just busy because of huge traffic.
Examine the bottleneck and eliminate it.
