[vfalies]

Hello,

When I use extension XML-RPC extension in dockerfile, I have the following message :

PHP Warning: PHP Startup: Unable to load dynamic library 'xmlrpc' (tried: /usr/lib/php7/modules/xmlrpc (Error loading shared library /usr/lib/php7/modules/xmlrpc: No such file or directory), /usr/lib/php7/modules/xmlrpc.so (Error relocating /usr/lib/php7/modules/xmlrpc.so: ecalloc: symbol not found)) in Unknown on line 0

Dockerfile :

FROM alpine:3.7

ADD https://php.codecasts.rocks/php-alpine.rsa.pub /etc/apk/keys/php-alpine.rsa.pub

    && rm -rf /var/cache/apk/*

WORKDIR /var/www/html

ENTRYPOINT ["/sbin/tini", "--"]

CMD ["/usr/sbin/php-fpm7", "-R", "--nodaemonize"]

Have I forgotten something ?

best regards

Let me check and get back to you.

I don't actually use this extension so you can imagine I haven't tested it.

[hernandev]

@vfalies confirmed bug, probably linked with Musl vs Glibc.

Unfortunately. I don't have a time frame to provide a fix, since it may be complicated to get working.

Do you actively use XML-RPC?

[vfalies]

@hernandev thanks for your investigation.

For me it's not mandatory to use PHP 7.2 version with this extension, I can use 7.1 version whom worked correctly. Therefore, in my case, it's not a priority.

I have writed this issue to inform you.

@vfalies Sorry for the delay in the response.

I indeed found the issue on the very same day, but the solution implies breaking compatibility.

The issue.

There's a bug or incompatibility with PHP 7.2 and xmlrpc extension that only allows xmlrpc extension to work if the xml extension gets compiled within PHP instead of shared.

Solution

Bundle XML extension within the php7-common package.

Problems with that

People who have scripts for installing the xml extension will break if the package stops from being published.
Also, removing the package now, in favor of a release would mean resign the whole repository to invalidate old versions.

Possible Solution 1

Bundle xml extension and provide a placeholder, empty php7-xml package that installs nothing.

Possible Solution 2

Wait a little bit to get a new version that fixes the bug, but it may take quite some time.

Still haven't decided yet on an approach to this. I'll let you know within the next couple days.

@vfalies I'm going to bundle xml into the common/core package to solve this, sorry for taking long to act on this.

@hernandev Thank you very much, it's ok for me.
