Change iteration to use size_t instead of int. The code should be
equivalent in all reasonable cases, but the original way this was
coded was causing a test failure with gcc 4.8.0 on ppc64. See
https://bugzilla.redhat.com/show_bug.cgi?id=915321 for additional
information.
Fix exit status for case of errors without warnings, continue after
errors when possible, add test case for parsing a file with content
stream errors on some but not all pages.
Change object type Keyword to Operator, and place the order of the
object types in object_type_e in the same order as they are mentioned
in the PDF specification.
Note that this change only breaks backward compatibility with code
that has not yet been released.
This fix eliminates a false test failure on some platforms and makes
the binary test work properly whether characters with the high bit
set, when treated as integers, are negative or not.
Original code was written before we could shallow copy objects, so all
the filtering was done by suppressing the output of certain keys and
replacing them with other keys. Now we can simplify the code greatly
by modifying shallow copies of dictionaries in place.
Read and write support is implemented for /V=5 with /R=5 as well as
/R=6. /R=5 is the deprecated encryption method used by Acrobat IX.
/R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.
This file used to exercise a zero offset test case when qpdf would
visit every object in the file. After the next commit, qpdf no longer
touches unreferenced objects, so a reference had to be added to
continue to have this file exercise the zero offset case.
For linearization tests where we are actually comparing the exact
output of the test with a known file, uncompress stream data so we can
see what's there. This makes looking at future changes a little
easier.
Allowing users to subclass InputSource and Pipeline to read and write
from/to arbitrary sources provides the maximum flexibility for users
who want to read and write from other than files or memory.
Previously only whitespace and comments did it. This fix is needed
for object streams whose last object is a literal (name, integer,
real, string) not terminated by space or newline.
Move object parsing code from QPDF to QPDFObjectHandle and
parameterize the parts of it that are specific to a QPDF object.
Provide a version that can't handle indirect objects and that can be
called on an arbitrary string.
A side effect of this change is that the offset used when reporting
invalid stream length has changed, but since the new value seems like
a better value than the old one, the test suite has been updated
rather than making the code backward compatible. This only effects
the offset reported for invalid streams that lack /Length or have an
invalid /Length key.
Updated some test code and exmaples to use QPDFObjectHandle::parse.
Supporting changes include adding a BufferInputSource constructor that
takes a string.
Add --copy-encryption and --encryption-file-password options to qpdf.
Also strengthen test suite for copying encryption. The strengthened
test suite would have caught the failure to preserve AES and the
failure to update the file version, which was invalidating the
encrypted data.
QPDFObjectHandle::{new,is,assert}Reserved, QPDF::replaceReserved
provide a mechanism to add objects to a PDF file when there are
circular references. This is a prerequisite to copying objects from
one PDF to another.
Breaking API change: length parameter has disappeared from the
StreamDataProvider version of QPDFObjectHandle::replaceStreamData
since it is no longer necessary to compute it in advance. This
breaking change is justified by the fact that removing the length
parameter provides the caller an opportunity to simplify the calling
code.
