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.
Since sourceforce automatically displays README-what-to-download.txt,
it is no longer necessary for this to be the default file on
Windows. Instead make one of the binary distributions the default on
Windows.
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.
