PyPDF2.errors.PdfReadError: EOF marker not found

[alisufian]

The following script originally hanged, but with PyPDF2==2.4.2 we get PdfReadError: EOF marker not found.

MCVE: PDF + Code

This file is 298MB with 21 pages.

from PyPDF2 import PdfReader

reader = PdfReader("01-006 2009-04-30 FRP NON CONFIDENTIAL PAP FILING.PDF")

Traceback

Traceback (most recent call last):

    raise PdfReadError("EOF marker not found")

PyPDF2==1.27.7 gives:

Traceback (most recent call last):
  File "/home/moose/foo.py", line 3, in <module>
    reader = PdfFileReader("01-006 2009-04-30 FRP NON CONFIDENTIAL PAP FILING.PDF")

    self.read(stream)
  File "/home/moose/Github/py-pdf/PyPDF2/PyPDF2/pdf.py", line 1828, in read
    line = self.readNextEndLine(stream, last1K)
  File "/home/moose/Github/py-pdf/PyPDF2/PyPDF2/pdf.py", line 2078, in readNextEndLine
    raise PdfReadError("Could not read malformed PDF file")
PyPDF2.errors.PdfReadError: Could not read malformed PDF file

Also with strict=False

that is the part:

            # Prevent infinite loops in malformed PDFs
            if stream.tell() == 0 or stream.tell() == limit_offset:
                raise PdfReadError("Could not read malformed PDF file")

the PDF is very odd... about 100 MB of null characters
after removing the threshold to look for the end marker, it can be opened. also some lines in the cmap needs to be stripped....

@MartinThoma,
this issue should be release, isn't it ?

Thank you for the reminder :-)
