Issue: Our functionality for merging PDFs from multiple vendor bills relies on PyPDF2. It is well-known that PyPDF2 is sometimes unable to manipulate even perfectly normal PDFs. To provide a helpful error message to the user when this happens (i.e. give them the names of the vendor bills corresponding to the offending pdfs), the `_get_unreadeable_pdfs()` function is called right before we try to merge the PDFs in `_merge_pdfs`. This function is meant to identify the offending PDFs and provide them to the user. However, _get_unreadable_pdfs did not notice the problem with 3 of my customer's pdfs, because the error was only triggered once the PdfFileWriter.write function was called in _merge_pdfs. This function, however, is not called in _get_unreadable_pdfs, therefore, it did not notice that anything was wrong. Fix: - Change _get_unreadable_pdfs so that it also makes a call to PdfFileWriter.write - As soon as PdfFileWriter.write fails once, it will continue failing when we append more PDF streams to the PdfFileWriter. I therefore suggest initialising a different PdfFileWriter at each iteration of the for loop in order for an offending PDF to not cause a false positive on subsequent PDFs. closes odoo/odoo#78966 X-original-commit: 0b4efd37376223806e7ff7273f520b2d17337bc8 Signed-off-by: Nicolas Lempereur (nle) <nle@odoo.com> Signed-off-by: Antoine Dupuis (andu) <andu@odoo.com>
