By combining --linearize with --compress-streams=n, we ensure that no
new compressed data will appear in linearized output, which makes the
output independent of zlib's output. There are other tests to ensure
that linearization works correctly with compression. This commit
involves changing some test outputs and test code as well just
updating test suites.

This was broken for cross-compilation and has probably been
unnecessary for several years now.
Also fix extraneous whitespace in related some tests.
|
|
Expose functions to the C API to create new loggers and to setLogger
and getLogger for QPDF and QPDFJob.
|

Prevent my future self or other contributors from using assert in
tests and then having that assert not do anything because of the
NDEBUG macro.

Run this:
for i in **/*.cc **/*.c **/*.h **/*.hh; do
clang-format < $i >| $i.new && mv $i.new $i
done

This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.
In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

add qpdf_oh_new_binary_unicode_string and qpdf_oh_get_binary_utf8_value
|
|
Accept empty string as type parameter in
QPDFObjectHandle::isDictionaryOfType and isStreamOfType
to allow for dictionaries with optional type.
|

Commit by ejb@ql.org using m-holger as author so git annotate gives
proper credit for changes.
|

Add methods isNameAndEquals, isDictionaryOfType, isStreamOfType
|

They have to be ot_* rather than qpdf_ot_* for compatibility.
* Different enumerated types are not assignment-compatible in C++, at
least with strict compiler settings
* While you can do `constexpr ot_xyz = ::qpdf_ot_xyz` in QPDFObject.hh to
make QPDFObject::ot_xyz work, QPDFObject::object_type_e::ot_xyz will
only work if the enumerated type names are the same.

* Handle error conditions that occur when using the object handle
interfaces. In the past, some exceptions were not correctly
converted to errors or warnings.
* Add more detailed information to qpdf-c.h
* Make it possible to work more explicitly with uninitialized objects

It was exercised in the pdf-linearize example but not in qpdf-ctest.

Thanks for the nudge from m-holger!

Return new qpdf_oh from qpdf_oh_wrap_in_array when input is already an array.
Update some doc comments in qpdf-c.h.

|
|
Use autoconf rather than ifdefs to determine what format string to use
for long long.

This makes all integer type conversions that have potential data loss
explicit with calls that do range checks and raise an exception. After
this commit, qpdf builds with no warnings when -Wsign-conversion
-Wconversion is used with gcc or clang or when -W3 -Wd4800 is used
with MSVC. This significantly reduces the likelihood of potential
crashes from bogus integer values.
There are some parts of the code that take int when they should take
size_t or an offset. Such places would make qpdf not support files
with more than 2^31 of something that usually wouldn't be so large. In
the event that such a file shows up and is valid, at least qpdf would
raise an error in the right spot so the issue could be legitimately
addressed rather than failing in some weird way because of a silent
overflow condition.

Setting encryption permissions for R >= 3 set permission bits in
groups corresponding to menu options in Acrobat 5. The new API allows
the bits to be set individually.

There was a missing free causing a memory leak in some test code. The
memory leak was not in library code.
|
|
For non-encrypted files, determinstic ID generation uses file contents
instead of timestamp and file name. At a small runtime cost, this
enables generation of the same /ID if the same inputs are converted in
the same way multiple times.

Make remaining calls to fopen and strerror use strerror_s and fopen_s
on MSVC.
|
|
fopen was previuosly called wrapped by QUtil::fopen_wrapper, but
QUtil::safe_fopen does this itself, which is less cumbersome.
