Wieland Lindenthal fd2b2a3f2a Feature: Optimize memory for pdf exports with attachments (#8861) ... * Change design of WP list PDF export to batches In order to keep memory consumption low when exporting WP as list in PDF, we split the work in batches of 100 work packages. In every batch we resize the attached photos and create a PDF. When all batches have been processed, we merge the PDF files via the command line tool `pdfunite` which fortunately comes with a package that we already require for text extraction. Only at the end, when the merged PDF is ready (and small) we load it into the ruby process to return the PDF's content with service's success. In every batch, we make sure that we remove all minimized images afterwards. And after merging the batch PDF files to the final PDF we also delete all batch PDFs. * Don't load the merged PDF file into the ruby process * Rename tempfile to final file name before storing. * Improve code structure.		4 years ago
