Print pdf don't delete file in var folder

[quienti]

Magento 2.0.2

If we print a pdf in Shipment :

We generate the file in folder var :

But, this file is never delete !

If we look in this file :
https://github.com/magento/magento2/blob/2.0/lib/internal/Magento/Framework/App/Response/Http/FileFactory.php#L99-L101

This code doesn't work for pdf files, but this code work fine for csv files like export customer

Hi @quienti ,
thank you for reporting this issue. Internal ticket MAGETWO-54083 was created.

Isn't it strange that the PDF's are dropped in the var root? I'd rather see them end up in a semantically named subdir or in the var/tmp dir.

Just going to put this here for search engine semantics. If you ever try to print pdf's from the frontend and get no such template {} error. It is because magento forgot to place two files in the frontend for the methods to access their templates..

copy the files from adminhtml/templates/info/pdf* to frontend/templates/info/pdf/*

mkdir vendor/magento/module-payment/view/frontend/templates/info/pdf
mkdir vendor/magento/module-offline-payments/view/frontend/templates/info/pdf

cp vendor/magento/module-payment/view/adminhtml/templates/info/pdf/* vendor/magento/module-payment/view/frontend/templates/info/pdf/
cp vendor/magento/module-offline-payments/view/adminhtml/templates/info/pdf vendor/magento/module-offline-payments/view/frontend/templates/info/pdf/

Hope this saves you hours of frustration from seemingly useless error message when trying to print pdf's from the frontend (or email their attachments!)
