How to uninstall a PHP extension?

[cracksalad]

Let's take kjdev/lz4 as an example:

pie install kjdev/lz4

pie uninstall kjdev/lz4
# No package found: kjdev/lz4

pie uninstall lz4
# Requested package name "lz4" is invalid; it should contain a forward slash, like "vendor/package".

pie uninstall ext-lz4
# Requested package name "ext-lz4" is invalid; it should contain a forward slash, like "vendor/package".

Am I missing something?

@cracksalad Did you install the extension using PIE, or some other method please? Please can you give the output of pie show --all?

Have not checked if it was actually installed successfully, should have done that:

$ pie install kjdev/lz4

Doing the same thing with sudo again:

Trying to replicate this behavior with xdebug/xdebug gives the following:

$ pie install xdebug/xdebug

$ pie show --all
# xdebug included (in green color with "from xdebug/xdebug")

$ pie uninstall xdebug/xdebug

So, I guess, the question now is, what is the difference between xdebug/xdebug and kjdev/lz4?

Maybe the answer to that question is the composer.json (especially the download-url-method option):

{
  "name": "kjdev/lz4",
  // [...]
  "php-ext": {
    "extension-name": "lz4",
    "download-url-method": "pre-packaged-source",
    "configure-options": []
  }
}

Is there anything else, I can do, to help fix that?

Thanks for that info, that helps. I suspect part of the issue is mixing up using sudo vs your regular user. The metadata that PIE uses for extensions it installs is located in the home directory of the user invoking PIE. This means, that if you install a package with sudo pie install ... when you run pie show it will not list that extension (as it looks in /home/your-user/... not /root/...)

However, as a separate topic, I'm interested about this first bit:

$ pie install kjdev/lz4
🥧 PHP Installer for Extensions (PIE) 1.2.1, from The PHP Foundation

$ echo $?
0

Does the output just stop like that, or did you truncate it? If it just stopped, then something definitely went wrong there; could you use pie install -vvv kjdev/lz4 for verbose output please, as that may indeed be a bug, but I'd need more info to look into it.

I did not truncate, it just stopped there.

I did run exactly the same command right now and it works totally fine. So, I am sad to say, that I can not gather any more verbose output at the moment. I will retry in a couple of hours and days.

Could it be something like a rate limit issue with GitHub maybe? That would explain, that it works sometimes and the output stopped just before the expected line:

Found prebuilt archive: https://github.com/kjdev/php-ext-lz4/releases/download/0.5.0/lz4-0.5.0.tgz

So GitHub seems to be involved here at least.

[asgrim]

Hmm maybe; lets leave this open for now and if you encounter the issue again, the verbose output will hopefully give a pointer as to what went wrong! Thank you! :)

[asgrim]

Just for reference, I saw another report of weirdness with this extension, that also self resolved: https://indieweb.social/@robjmills/115502210495587448

I'm gonna assume it was some temporary issues with GH perhaps, not sure what else could explain this.

[cracksalad]

Just to be precise, it is a different extension (kjdev/lz4 vs kjdev/zstd) but both use the config "download-url-method": "pre-packaged-source". So it might indeed be related.

[asgrim]

Yep that's a fair point 👍
