Allowed memory size of ... bytes exhausted

[cgebhard]

Description of the problem

ZipStream dies in mid stream with error:
[message] => Allowed memory size of 402653184 bytes exhausted (tried to allocate 131072 bytes)
[file] => vendor/maennchen/zipstream-php/src/File.php
[line] => 131

ZipStream works fine for smaller archives. This one dies at around 19.6MB. 10Ks of small files around 7000 bytes each.

Example code

$Opt = new ZipStream\Option\Archive();
$Opt->setComment('Test');
$Opt->setSendHttpHeaders(true);
$Opt->setFlushOutput(true);

 $Zip = new ZipStream\ZipStream('test.zip', $Opt);
// loop 10Ks of iterations... {
$this->Zip->addFileFromPath('testloop.html', '/filesystem/file_location');
// endloop }
$Zip->finish(); 

Informations

• ZipStream-PHP version: 2.1.0
• PHP version: 7.3.28

Please include any supplemental information you deem relevant to this issue.

I've tried changing lots of options with no luck. These changes all produced the same error:

$Opt->setLargeFileMethod(ZipStream\Option\Method::STORE());
$Opt->setLargeFileSize(3000000);
$Opt->setDeflateLevel(-1); // tried 3 and 6 too
$Opt->setEnableZip64(true); // tried false too

You need to edit your php.ini to allow more memory (memory_limit).

[maennchen]

@cgebhard ZipStream needs to store a small piece of information until the end about every file.

Given that the memory is not used by the output buffer (please verify), that's most likely the culprit.

There's however nothing we can do about that and you'll need to raise the memory limit to account for that.
