Upload filesize miscalculation results in File Size to Big

[Luppie]

▶ Reproduction steps

1. Check max. upload size in Settings -> Image Upload
   
2. Update from 3.18.0 to 3.20.1 and/or 3.20.4
3. Check max. upload size in Settings -> Image Upload
   

😢 Unexpected result

The serverside PHP setting 16MB is miscalculated as 177.7kb

📃 Error log message

Upload File size is to big

How you configured those 16MB in php.ini?

 

[Luppie]

I'm running PHP in FPM mode, the upload size is configured in /etc/php-fpm.d/144857680022849.conf (per domain configuration)


This is the relevant configuration part:

php_admin_value[upload_max_filesize] = 16777216
php_admin_value[post_max_size] = 16777216

As you can see in the screenshots the value hasn't changed (serverside) it is only calculated differently after the upgrade.

 

[Rodolfo]

That won't work.

php.ini takes PHP short size notation (16M for 16MB).

no just no, you did it all wrong! it goes by normal calucation method. in php.ini you do in M format. if you want 16MB then you set 16M as upload limit in php.ini. Do not use 16777216 since that will make php.ini not understanding what it means.

I've changed it to 16M and it is working. Thank you for pointing that out.
Since I always try to learn from my mistakes, can someone explain it to me why it was working in 3.18 and not working in 3.20 ?

 

[Rodolfo]

I have never used MB in php.ini values, I can't say that such nomenclature worked before. At least in my scope, perhaps there's some fuzzy mode that I'm unaware of.

I'm just following the official PHP configuration directives.
upload_max_filesize is an integer and integers never contains alpabetic characters.
Shorthand notation may be used.

upload_max_filesize int
The maximum size of an uploaded file.

post_max_size must be larger than this value.

When an int is used, the value is measured in bytes. Shorthand notation, as described in this FAQ, may also be used.

Looking at this I'm not doing it so wrong after all.
