Deprecation warnings running php v8?

[moviebrain]

Would there be any pushback if I attempted a PR to resolve some of the deprecation warnings I see running on php v8? I don't know how quickly php dev moves, but it is my understanding a good number of these will become hard breaks in php v9?

For the latter trim() warning (the very last appears to be the code checking if a mp3 tag exists?) , it looks like a null coalescing assignment operator will work for > php7, but I don't want to try and make a PR that is breaking for anyone, or if it's not really wanted by anyone. I am not really certain what the targeted runtime is, and I don't want to try this and break stuff without knowing any better.

Maybe it'd just be QoL and I'm the only one who gets that squiggle feeling when the terminal pukes out pages of warnings?

I for one would really appreciate fixes for these. I use merge in a chain of commands, which currently can't proceed after the merge because of the error result.

No actually this would be great. One minor detail: I'm into this right now (currently analyzing) and I would like to prevent you working on this just to see in a week that there have been updates. I would love to invest more time on this, but since it is started, I will perform my commits. After this you are welcome to do a PR.

I'm totally aware that m4b-tool needs some love again and since there is so much deprecated stuff, this is something that needs to be done as soon as possible.

As a workaround you could either change your php.ini:

error_reporting=E_ALL & ~E_DEPRECATED

or run php with inline ini options:

php -d "error_reporting=E_ALL & ~E_DEPRECATED" m4b-tool.phar #...

I would love to get some feedback on this.

Excellent. I’ll circle back around to this next weekend when I have some time then, see where it’s at. Thanks for the reply.

The marked commit above fixes some of the deprecations, but also alters the error_reporting to no longer contain E_DEPRECATED via:

// disable E_DEPRECATED errors
if(!getenv("M4B_TOOL_FORCE_INI_ERROR_REPORTING")) {
    $errorReportingLevel = error_reporting();
    error_reporting($errorReportingLevel & ~E_DEPRECATED);
}

This basically means it takes the current error_reporting level of the php.ini and removes the E_DEPRECATED flag, as long as you not set the environment variable M4B_TOOL_FORCE_INI_ERROR_REPORTING=1. I hope this will meet your requirements to not have this absolutely useless error messages in your command line and has no side effects (it did not have in my tests).

One deprecation message is caused by a dependency TimeUnit (php-time package), that is also my work. I'll try to update the package asap.

In the next weeks I'll try to make m4b-tool as php8 ready as possible without breaking stuff. If you can't build m4b-tool yourselves, I try to publish a new pre-release in the next days containing these code updates.

Thank you very much for the help and your work in general.

[moviebrain]

Thanks @sandreas for all this work. It is greatly appreciated!

New Pre-Release is out - let me know if it works.

[abhilesh]

Happy to report that deprecation warnings are gone in the latest Pre-Release version! Thanks a lot!

Great :-) Thanks for the feedback.

I have a somewhat related question about this, is it possible to use the alpine package php81 in place of php8? I have a docker project that depends on this project, and I really need to upgrade the version of alpine that my project uses, but the latest version that still includes php8 is v3.16. So I was just curious if 8.1 is a drop in replacement or not before I go down the rabbithold of trying it.

@csandman
Thanks for pointing out. I think it is time for an upgrade. php 8.1 should work exactly the same. Maybe I'm going to change the base image like this:

• Switch the base image to php:cli-alpine
• Remove all manual php installation steps

I did not test it, but the future Dockerfile will be probably look somewhat to this:
