Is it possible to use wb instead of wb+ fopen mode in openToFile() in AbstractWriter in order to use compress.zlib:// ?

[cmanley]

If I try to write to a compressed CSV file, then I get an exception using the file wrapper compress.zlib://

I think it has to do with the seekable file mode used here:
$this->filePointer = $this->globalFunctionsHelper->fopen($this->outputFilePath, 'wb+');

Simply removing the + from the file mode seems to solve the problem but I'm not sure if box/spout needs it somewhere for something.

B.t.w. this is the exception and errors I get when I open a file with a compress.zlib wrapper using the latest v2 release:

PHP Warning:  fopen(compress.zlib://art.csv.gz): failed to open stream: operation failed in lib/box/spout/src/Spout/Common/Helper/GlobalFunctionsHelper.php on line 25
PHP Fatal error:  Uncaught Box\Spout\Common\Exception\IOException: File pointer has not be opened in lib/box/spout/src/Spout/Writer/AbstractWriter.php:175

Fix merged in openspout/openspout#66 and released in openspout:v3.7.4

Thanks! Is it possible to merge it into the 2.* branch too?

There's no branch 2.x in the community fork I'm maintaining at https://github.com/openspout/openspout, sorry

If you need a backport, I suggest leveraging https://github.com/cweagans/composer-patches

Alright thanks. I only just noticed that the patch was in openspout. That's new to me.
