Debian Bookworm has problems with memcached

[ne20002]

After installing the current dev version from hub.docker.com I get a few warnings about extensions not being loaded (I haven't faced this with my local tests so it seems as if I might have missed something).

PHP Warning:  PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gd.so (libpng16.so.16: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gd.so.so (/usr/local/lib/php/extensions/no-debug-non-zts-20220829/gd.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

The only problem I see is that images are not displayed in the web interface. I don't see any issues when using Tusky as client. The memcache may also affect performance.

The changes to the Dockerfile is just an update

• from bullseye to bookworm
• from php 8.1 to 8.2

I already added

zlib1g-dev \
libssl-dev \

to the packages installed as those have been missed and needed to be installed with the update to php 8.2 (as described here.

Any help on this issue is most welcome.

I'm currently a bit confused on the no-debug-non-zts-20220829 part

But all four missing files are there. Either the first or second load shall find the file.

I'm not sure if this is related to #262 but it's worth a test. It's not related.

[ne20002]

I have updated my setup and reproduce the problem locally now. The Alpine image is not affected, it's clearly a problem with bookworm, there are many posts online related.

PR #14412 will align the dev container setup with the docker setup. This should help finding the problem with memcached in bookworm.
