The joomla-framework/archive package has been updated to use the PHP ZipArchive, because the zip functions we used before are deprecated in favor of the Object API.

This is an issue that we inherited from PHP, so we can't do much about it. Nevertheless we'll investigate the possibility of a workaround. Can't promise anything, though.

Tested it also with Akeeba Backup Core. The main zip contains, 6 other zips. But there are no problems here. The installation speed is more or less the same.

This resolves the issue for me, use directly ZipArchive::getFromIndex instead of first getting and reading the file with ZipArchive::getStream. This should happen with all larger zip files because the read operation takes longer.

	/**
	 * Extract a ZIP compressed file to a given path using native php api calls for speed
	 *
	 * @param   string  $archive      Path to ZIP archive to extract
	 * @param   string  $destination  Path to extract archive into
	 *
	 * @return  boolean  True on success
	 *
	 * @since   1.0
	 * @throws  \RuntimeException
	 */
	protected function extractNative($archive, $destination)
	{
		$zip = new \ZipArchive;

		if ($zip->open($archive) !== true)
		{
			throw new \RuntimeException('Unable to open archive');
		}

		// Make sure the destination folder exists
		if (!Folder::create($destination))
		{
			throw new \RuntimeException('Unable to create destination folder ' . \dirname($path));
		}

		// Read files in the archive
		for ($index = 0; $index < $zip->numFiles; $index++)
		{
			$file = $zip->getNameIndex($index);

			if (substr($file, -1) === '/')
			{
				continue;
			}

			$buffer = $zip->getFromIndex($index);

			if ($buffer === false)
			{
				throw new \RuntimeException('Unable to read ZIP entry');
			}

			if (File::write($destination . '/' . $file, $buffer) === false)
			{
				throw new \RuntimeException('Unable to write ZIP entry to file ' . $destination . '/' . $file);
			}
		}

		$zip->close();

		return true;
	}

@steffans Tested your code with 3.9.23 and now it takes also 15 seconds.

@steffans can you make a PR against https://github.com/joomla-framework/archive ?

or @nibra will you create the PR?

PR is ready: joomla-framework/archive#24

@HLeithner We leave this issue open until the framework PR has been merged and we will have a PR for updating the framework package in staging, right?

yes please

I have the same issue - also emerged on an attempted YTPro upgrade.

Tested the same upgrade on a 3.9.22 (fine) and 3.9.23 (timed out with a 500 second limit). Zoolanders Essentials timesout too - but other extensions have loaded ok. The issue is the same whether using the update script, installing from a directory, or uploading the package file.

I tried applying the patch from the PR to libraries/joomla/archive/zip.php - but unless I need to delete a cache or something, it didn't make any difference.

@vingle This is the correct directory: joomla_root/libraries/vendor/joomla/archive/src/Zip.php

Ah - thanks for the correction – yes that works for me now :)

Just to confirm...

• I installed a Joomla 3.9.22 on a test website on MAMP 6.2 / PHP 7.4.12
• I installed Yootheme J3_2.3.19 -> OK
• I updated Joomla to 3.9.23
• I updated Yootheme to J3_2.3.21 -> FAILED
• I updated Joomla to 3.9.24-dev
• I pudated Yootheme to J3_2.3.21 -> OK

thx I keep this issue open until 3.9.24 is released

I applied the patch to the zip.php, and tried updating from yootheme j3_2.3.21 to yootheme j3_2.3.23 and 24 both fail with an unable to find manifest file. I re-uploaded the unchanged zip.php file and the update for yootheme pro installed fine.

Joomla 3.9.23
PHP 7.4.11

@Stevec4 did you tested #31514 ?

Sorry I wasn't clear Harald, the patch I applied was from the #31514 PR.

Steve

@Stevec4 please test https://github.com/joomla/joomla-cms/releases/tag/3.9.24-rc I'm closing this because this should be solved
