@alexdowad any idea how to fix the iconv test?

Dear @mvorisek, I don't mind having a look at it. Could you share a link to the output of the failing test?

Do you have anything like a Dockerfile which I could use to run your tests locally?

thanks for a quick reaction, the test failures are here: https://github.com/php/php-src/runs/6609199312?check_suite_focus=true#step:10:4351

I do not have a DockerFile directly, but you should be able to replicate the failures using alpine:3.15 image,

php-src/.github/actions/apt-x64/action.yml

packages and

php-src/.github/actions/configure-x64/action.yml

Warning: iconv(): Wrong encoding, conversion from "UTF-8" to "UTF-8//IGNORE" is not allowed in /__w/php-src/php-src/ext/iconv/tests/bug48147.php

Consider to install libiconv-dev, if possible.

gnu-libiconv-dev is already being installed and there is probably no other alternative iconv package - https://pkgs.alpinelinux.org/packages?name=*iconv*&branch=edge&arch=x86_64

[nikic]

Please don't mix the CI configuration for alpine and ubuntu -- at least as far as package installation and PHP configuration is concerned. This is going to be a big mess otherwise.

gnu-libiconv-dev is already being installed […]

Then I suggest to verify that it is actually used; ICONV_IMPL and ICONV_VERSION or phpinfo() should yield the relevant info. Also, cat config.log after ./configure might generally be a good idea during testing this PR.

the iconv tests look quite broken although the GNU iconv lib is installed:

But https://github.com/php/php-src/runs/7506541587?check_suite_focus=true#step:6:653:

checking if using GNU libiconv... no

thanks, I have found docker-library/php#1121 and docker-library/php#240

also related docker-library/php#1264 to the official images

I am closing this as the PR can't apply, nor does it address Nikita's comment wrt to splitting the actions to multiple files.
