* Merge overloaded functions by adding default values
* Remove non-const methods that are identical to const methods
|
|
|
|
* Change DLL_EXPORT to libqpdf_EXPORTS (internal to the build). The
new name is cmake's default, is more conventional, and is less
likely to clash with other symbols.
* Add QPDF_DLL_PRIVATE for non-Windows
* Make logic around when to define QPDF_DLL et al more explicit
* Add detailed comments

Prior to the cmake conversion, several private classes had methods
that were exported into the shared library so they could be tested
with libtests. With cmake, we build libtests using an object library,
so this is no longer necessary. The methods that are disappearing from
the ABI were never exposed through public headers, so no code should
be using them. Removal had to wait until the window for ABI-breaking
changes was open.

Add comments to force line breaks, parenthesize function arguments
that are contatenated strings, etc. -- these kinds of changes improve
clang-format's results and also cause emacs cc-mode to match
clang-format. After this type of change, most of the time, when
clang-format and emacs disagree, clang-format is better.

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

Also add a pkg-config runtime test that would have caught the error.
|
|
Some platforms need it for atomic<long long> but not for atomic<int>.
|
|
The executables that libtool built invoked the underlying binary with
an "lt-" prefix. The code contained numerous workarounds for testing,
which can now be removed.

It's better to just make it a .hh file to reduce confusion.

This is so it will fit on one line after a qtest upgrade allows us to
split lines.

This was mainly to get comments about defaults out of constructor
initializer lists where their fragile when a code formatter is being
used.

The PDF spec only allows UTF-16BE, but most readers seem to accept
UTF-16LE as well, so now qpdf does too.
|
|
This was unintended behavior that was added back for backward
compatibility. It is intentionally undocumented.
|
|
There are codepoints in PDFDoc that are not valid UTF-8 but map to
valid UTF-8. We were handling those correctly with bidirectional
mapping.
However, if those same code points appeared in UTF-8, where they have
no meaning, they were left as fixed points when converting to PDFDoc,
where they do have meaning. This change recognizes them as errors.

Remove test for type == /XObject in QPDFObjectHandle::isFormXObject
as type value is optional (as per spec 8.10.2).
Replace code to test for /Form in QPDFJob::shouldRemoveUnreferencedResources
with a call to isFormXObject.

If we're opening a PDF file to copy its encryption information or
attachments, its version doesn't need to influence the output version.

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.

This will be able to be replaced with QUtil::make_shared_array
|
|
Replace PointerHolder arrays wherever it can be done without breaking ABI.
