System requirements check says missing mailparse but PHP shows it loaded

[sethicis]

The Issue

I'm working on a Docker image for PHP8-alpine with apache2 and uvdesk/community-skeleton. I got the image to build and uvdesk setup to startup, but when uvdesk does its requirements check it always fails on the mailparse extension verification. (See below)

I verified the mailparse extension is loaded with the below methods:

php -i | grep -i mailparse
# output
/usr/local/etc/php/conf.d/docker-php-ext-mailparse.ini,
mailparse
mailparse support => enabled
mailparse.def_charset => us-ascii => us-ascii

php -r 'var_dump(get_loaded_extensions());' | grep -i mailparse
# output
  string(9) "mailparse"

I'm kind of at a loss as to why the uvdesk requirements check is saying the mailparse extension is missing. Any assistance that you can provide would be much appreciated.

Fyi, @tyancolte

Once you can installed the mailparse extension with version defined like this:

php-mailparse php8-mailparse

Kind Respects, Uvdesk Team

@Komal-sharma-2712 , those packages don't exist in alpine. You can see a full list of what's available in alpine here

There is a php8-pecl-mailparse, which I originally used, but that doesn't get linked properly, which is why I switched to using install-php-extensions mailparse imagick.

install-php-extensions comes from mlocati/php-extension-installer which is a tool built to assist in adding php extensions to docker images. You can read more about it here.

@Komal-sharma-2712 , how does the system requirements check for mailparse work? Is it not just using get_loaded_extensions in PHP?

[sethicis]

Ok, I found where it does the system requirement checks. https://github.com/uvdesk/community-skeleton/blob/master/src/Controller/ConfigureHelpdesk.php#L79

It uses extension_loaded to check, so I ran the same logic in the cli:

php -r 'var_dump(extension_loaded("mailparse"));'
bool(true)

[sethicis]

Ok, I've got this figured out. The issue has to do with how the base image is created. In my Dockerfile I install fpm and php packages via apk, but the php8 I'm running is baked into the image itself.

The baked in version of PHP is compiled with a different extensions directory and scan directory set. This is why when I check php-cli everything seems to be present, but the php-fpm can't find mailparser.

install-php-extensions installs extensions to the location that the base image version of php8 (php-cli), expects, so it reports everything is ok. While php-fpm, installed via apk is looking in a completely different place for its configs and extensions, so it reports things are missing.

The solution I'm working on is changing my image to be based on php8.0:fpm-alpine, so that both php-cli and fpm have the same compiled configuration. Then I'm going to use install-php-extensions to install any missing extensions.

Thank you all for your help. This is no longer an issue with uvdesk, just my own Docker image work -- closing this issue.
