php8.2.15 removed ftp extension

[Angoll]

Hello!
The update from 8.2.14 to 8.2.15 removed the ftp extension (see 7512769), extension that needs to be statically compiled (see #236)

I believe that should not be removed in a minor upgrade. 😢
We fixed to the 8.2.14 but we would like to have minor upgrades without having to manage images from scratch.

Thanks

Hmm, I think we need to dig into the "Before PHP 7.0.0" bit of https://www.php.net/manual/en/function.ftp-ssl-connect.php, because from the docs, this should be working fine. 😕

[tianon]

Ah, this is due to https://github.com/php/php-src/blob/php-8.2.15/ext/ftp/config.m4#L21-L24, but just passing --with-openssl is not enough to let it know that we do have PHP with OpenSSL support. 😞

Confirmed, installing libssl-dev and invoking docker-php-ext-configure ftp --with-openssl-dir=/usr before docker-php-ext-install ftp gives me ftp_ssl_connect() successfully.

More concretely:

FROM php:8.2

RUN apt-get update && apt-get install -y libssl-dev

RUN docker-php-ext-configure ftp --with-openssl-dir=/usr \
	&& docker-php-ext-install ftp

Will the ftp be added back in the future Docker images?

I need to know it to decide whether to apply manual ftp installation temporarily or permanently. Thanks.

[tianon]

Unfortunately, we don't plan to add it back to the default set, no.

[Angoll]

@tianon thanks for the workaround and clarifying that is not be added back.

Is there any reason that got the package removed in the first place in a minor upgrade?

Thanks

[tianon]

It should've only been included in the 5.x versions in the original PR that added it (because the underlying issue was fixed in 7+) 😅

The other option we considered was to remove it in the previous version as a normal image update (without waiting for a version change), and we opted for the slightly more conservative switch instead.

Confirmed, installing libssl-dev and invoking docker-php-ext-configure ftp --with-openssl-dir=/usr before docker-php-ext-install ftp gives me ftp_ssl_connect() successfully.

FWIW: I've intentionally listed the necessary steps in #1482, so that it is not necessary for someone else to research this 😅

More concretely:

FROM php:8.2

RUN apt-get update && apt-get install -y libssl-dev

RUN docker-php-ext-configure ftp --with-openssl-dir=/usr \
	&& docker-php-ext-install ftp

Do you mind to explain how to use this solution? From what I understand I'm supposed to create Dockerfile with from/run commands. Where do I place Dockerfile and how do I call it from my Docker compose file? Can those commands be run from Ubuntu terminal and how?
Thank you.
