PHP Class `finfo` not found #1127

mho22 · 2024-03-21T15:49:22Z

I encountered an issue while experimenting with PHP CLI.

node node_modules/.bin/cli test.php

> Fatal error: Uncaught Error: Class "finfo" not found in /mho22/works/php-wasm-issue/test.php:3
> Stack trace:
> #0 {main}
>   thrown in /mho22/works/php-wasm-issue/test.php on line 3

It seems like PHP's built-in extensions like fileinfo are not found. Is this correct ?

Here's step by step to reproduce the problem

mkdir php-wasm-issue

cd php-wasm-issue

npm install @php-wasm/cli

test.php

<?php

$finfo = new finfo( FILEINFO_MIME );

echo json_encode( $finfo );

node node_modules/.bin/cli test.php

The text was updated successfully, but these errors were encountered:

Oh interesting! Are we missing a php.ini setting? Or perhaps the --disable-all flag during the compilation removes this extension from the build?

mho22 · 2024-03-21T21:43:05Z

@adamziel Do you know a way for me to help find how to solve this ?

adamziel · 2024-03-21T22:10:44Z

@mho22 yes! One way would be to compare the phpinfo() output at https://playground.wordpress.net/?url=/phpinfo.php with a regular PHP installation that has that class and figure out what's different with respect to the finfo class. I think we need to add a flag to ./configure call that would be similar to --enable-finfo. I'm not sure what the exact name is, there should be some hints in https://github.com/php/php-src/tree/master/ext/fileinfo and https://github.com/php/php-src/ in general.

mho22 · 2024-03-21T22:34:22Z

@adamziel I suppose two screenshots with PHP8.2 binary phpinfo() method and PHP-WASM8.2 phpinfo() could be interesting to view here but these views are gigantic.

So, here is a little screenshot of the only thing different when I search for finfo or fileinfo between the two. This element appears on PHP8.2 binary, not PHP-WASM8.2.

Next is the data from Configure Command. I think the best would be to paste what I have. And I hope this will be readable enough :

Now is time to investigate.

adamziel · 2024-03-21T22:52:41Z

This could be relevant:

https://github.com/php/php-src/blob/530e0d68ebee5b21ad10311115c392072b8b4168/ext/fileinfo/config.m4#L1-L5

I'm not sure if --disable-all impacts that flag at all.

mho22 · 2024-03-21T23:11:17Z

It seems like --disable-all disables all extensions which are enabled by default :

https://github.com/php/php-src/blob/530e0d68ebee5b21ad10311115c392072b8b4168/configure.ac#L1099

This does not confirm that it disables fileinfo either.

That said, I can't find anything about "re-enable" disabled default extensions, like :

--disable-all
--enable-fileinfo
--enable-curl

adamziel · 2024-03-21T23:43:44Z

Perhaps it's time to remove --disable-all and tactically disable specific extensions instead, then.

mho22 · 2024-03-21T23:52:09Z

@adamziel Alright, I'm working on it.

mho22 · 2024-03-22T01:45:03Z

@adamziel I tried removing --disable-all and recompiled only in 8.3 but an error occurred quickly. opcache was responsible of that error. I then added --disable-opcache and the recompilation of 8.3 succeeded.

I ran a npm run php -m to list the available php-wasm extensions and two new extensions appeared :

fileinfo
posix

I suppose this could be the solution. I am currently busy recompiling every PHP versions before launching the tests.

By the way, I was wondering : could there be a way to make --with-curl work for php-wasm ?

adamziel · 2024-03-22T09:14:38Z

Lovely! 🤞it will just work for all the PHP versions :)

About curl, you’d need to add libcurl directory here and provide a wasm build of the library:

https://github.com/WordPress/wordpress-playground/tree/trunk/packages/php-wasm/compile

From there, you could add —with-curl to ./configure in the same way as other extensions are provided.

mho22 · 2024-03-22T09:26:09Z

@adamziel It seems when i npm run recompile:php:web I get the given error :

#38 34.22 configure: error: iconv does not support errno

And this has been said about that :

As of PHP 8.0.0, iconv implementation which do not support errno
(i.e. non POSIX conforming implementations) are no longer
supported.

https://bugs.php.net/bug.php?id=80585

I added this :

# Add iconv if needed
RUN if [ "$WITH_ICONV" = "yes" ]; \
	then \
		echo -n ' --with-iconv=/root/lib ' >> /root/.php-configure-flags; \
		echo -n ' /root/lib/lib/libiconv.a' >> /root/.emcc-php-wasm-sources; \
		# PHP >= 8.0 posix is no longer supported.
		# PHP ≤= 7.4 posix is supported.
		if [[ "${PHP_VERSION:0:1}" -ge "8" ]]; then \
			echo -n ' --disable-iconv ' >> /root/.php-configure-flags; \
		fi; \
	fi;

Not working at the moment. Anyways, I am on it.

Concerning --with-curl do you mind if I add it to php-wasm ? Or you suggested me doing this locally ?

adamziel · 2024-03-22T09:34:12Z

@mho22 aha, WITH_ICONV is only set to yes for the kitchen-sink build but not for the light build. without the --disable-all that part of the DOCKERFILE might need a top-level else as follows:

RUN if [ "$WITH_ICONV" = "yes" ]; \
	then \
		echo -n ' --with-iconv=/root/lib ' >> /root/.php-configure-flags; \
		echo -n ' /root/lib/lib/libiconv.a' >> /root/.emcc-php-wasm-sources; \
		# PHP >= 8.0 posix is no longer supported.
		# PHP ≤= 7.4 posix is supported.
	else \
		echo -n ' --disable-iconv ' >> /root/.php-configure-flags; \
	fi;

mho22 · 2024-03-22T09:35:39Z

There are also two WITH_ICONV for node build. I suppose I can "clean" this ?

adamziel · 2024-03-22T09:36:13Z

Concerning --with-curl do you mind if I add it to php-wasm ? Or you suggested me doing this locally ?

@mho22 I would be stoked to have this in php-wasm, you would enable a lot of developers to explore new use-cases and run their code in Playground 🔥

If you can get it to build, this PR should give curl access to the network.

mho22 · 2024-03-22T10:58:41Z

@adamziel It seems npm run recompile:php:web:light:8.3 [ who has no WITH_ICONV enabled ] kept throwing :

#38 34.22 configure: error: iconv does not support errno

I added --without-iconv and there was no iconv error anymore. Instead, I had :

44.14 checking whether to enable XMLReader support... yes
44.14 configure: error: XMLReader extension requires LIBXML extension, add --with-libxml

So I added --disable-xmlreader in the RUN if [ "$WITH_LIBXML" = "yes" ]; else [ it seemed to be missing ].

I also tried by removing --disable-iconv and it worked too. I suppose this is correct.

Running every recompile and then testing. Let's find out if everything works fine. I keep you posted.

P.S.: I am glad to hear that lib-curl could probably be added, but I should mention that I will try to add it. I am absolutely not confident in my success.

mho22 · 2024-03-22T13:09:38Z

@adamziel Only one test failed at this point :

FAIL  src/lib/steps/wp-cli.spec.ts > Blueprint step wpCLI > should run wp-cli commands
    AssertionError: expected '#!/usr/bin/env php\n' to match /Success: Created post/
        ❯ src/lib/steps/wp-cli.spec.ts:35:23

The expected value is too specific to be a "real" error. I suppose the result.text returns the first line of the file here #!/usr/bin/env php\n instead of the result that could possibly be /Success: Created post/.

But I will wait for your insight about this.

Anyways, this sounds promising I suppose. Let's make the Pull Request now.

mho22 · 2024-03-25T10:37:34Z

@adamziel I am trying to list the PHP extensions from @php-wasm/web but this code gives me a module error :

npm install @php-wasm/web

index.js

import { WebPHP } from '@php-wasm/web';

const php = await WebPHP.load( '8.3' );

php.writeFile( '/index.php', `<?php echo phpinfo(); ?>` );

await php.run( { scriptPath : './index.php' } );

node index.js

I am probably missing something obvious. But I need some enlightenments.

I tried this :

node --experimental-wasm-modules index.js

adamziel · 2024-03-25T11:25:15Z

@php-wasm/web is meant to be used in web browsers. Perhaps @php-wasm/browser would be a better package name. What you're looking for is likely:

import { NodePHP } from '@php-wasm/node';

mho22 · 2024-03-25T11:31:50Z

Yeah, that was indeed obvious. Apologies for the silly question. I should probably ask you what the quickest way is to list the PHP extensions of php-wasm/web/light using the '@php-wasm/web' package instead.

In other words, how can I list the php extensions present in the light version when I recompile it and rebuild it ?

adamziel · 2024-03-25T11:48:05Z

Aha! I'd go to http://localhost:5400/website-server/, load the PHP version you've rebuilt, and run this in the dev tools:

document.body.innerHTML = (await playground.run({ code: `<?php phpinfo(); ?>` })).text

…1132) Based on #1127. This PR enables FileInfo and Posix extensions in PHP previously disabled by `--disable-all`. ## What problem is it solving? It allows the use of `new finfo()`. Previously, the following error occurred : ``` node node_modules/.bin/cli test.php > Fatal error: Uncaught Error: Class "finfo" not found in /mho22/works/php-wasm-issue/test.php:3 > Stack trace: > #0 {main} > thrown in /mho22/works/php-wasm-issue/test.php on line 3 ``` ## Testing Instructions 1. `mkdir php-wasm-issue && cd php-wasm-issue` 2. `npm install @php-wasm/cli` 3. `touch test.php` : ```php <?php $finfo = new finfo( FILEINFO_MIME ); echo json_encode( $finfo ); ``` 4. `node node_modules/.bin/cli test.php`

Fixes #1127 ## What is this PR doing? It enables `fileinfo` support in kitchen-sink and Node and adds tests for it. ## What problem is it solving? Allows users to use `fileinfo`. ## How is the problem addressed? By fixing a bug in the build script that prevented `fileinfo` from being enabled. ## Testing Instructions - ensure tests pass
