Removing an element from a set with iterator is constant time, and
std::set specifies that other operations on the set do not invalidate
existing iterators.

|
Some new symbols were exported.
|
|
These markers are being added for nested classes that are already
marked with QPDF_DLL_CLASS. They don't make any different on Linux,
but they matter on Windows.

Replace operator== and operator!=, which were testing for the same
underlying object, with isSameObjectAs. This change was motivated by
the fact that pikepdf internally had its own operator== method for
QPDFObjectHandle that did structural comparison. I backed out qpdf's
operator== as a courtesy to pikepdf (in my own testing) but also
because I think people might naturally assume that operator== does a
structural comparison, and isSameObjectAs is clearer in its intent.

Expose functions to the C API to create new loggers and to setLogger
and getLogger for QPDF and QPDFJob.

QPDFValueProxy wasn't a good name for it. We decided the evil of
having the header file be named QPDFObject_private.hh was less than
the evil of having the class be named something other than what it
should have been named.

Preparing to change the class name back to QPDFObject
|
|
I decided that it's actually fine to copy a direct object to another
QPDF. Even if we eventually prevent a QPDFObject from having multiple
parents, this could happen if an object is moved.
|
|
When a QPDF is destroyed, changing indirect objects to direct nulls
makes them effectively disappear silently when they sneak into other
places. Instead, we should treat this as an error. Adding a destroyed
object type makes this possible.
|
|
|
|
Also, since it's just there for compatibility, we don't need to add
new object types to it.

Add copy_if_fallback and explain how it differs from copy_if_shared.

* Just removing a header file would cause build errors with no hint as
to what happened. This way, people get a warning rather than error
for the life of qpdf 11, and the warning tells them what to do.
* This avoids build surprises resulting from having two versions of
QPDF headers installed at once. If you were building code out of a
checkout of qpdf but had an older version installed on your system,
if your code included <qpdf/QPDFObject.hh>, everything would work,
but then your code would break without QPDFObject.hh later.

This is in preparation for restoring a QPDFObject.hh to ease the
transition on qpdf_object_type_e.
This commit was created by
* Renaming QPDFObject.cc and QPDFObject.hh
* Replacing QPDFObject\b with QPDFValueProxy (where \b is word
boundary)
* Running format-code
* Manually resorting files in libqpdf/CMakeLists.txt
* Manually refilling the comment in QPDF.hh near class Resolver

Since Buffer has always implemented its copy constructor with a deep
copy, its Members object will never have multiple owners. Change to unique_ptr.
Also implement move constructors for Buffer, since there may be cases
where a deep copy is not needed.

On destruction of the QPDF object replace all indirect object references
with direct nulls.
Remove all existing code to release resolved references.
Fixes performance issue due to interaction of resetting QPDFValue::qpdf and
og members and prior code.

This required moving some newly inlined functions back to the cc file,
but that seems to have had no measurable performance impact.

Also, modify QPDFObject::swapWith to update the ObjGens of the swapped
objects.
Modify QPDF::newIndirect and QPDF::updateCache to keep object ObjGens
up to date.
|
|
|
|
|
|
Modify QPDFParser::parse to call QPDF::getObject instead.
|
|
Add a new obj_cache entry or update an existing entry in place.
|
|
|
|
|
|
|
|
Also change QPDF::replaceObject and QPDF::swapObjects such that the
QPDFObject assigned to an og in the obj_cache is never replaced; only
QPDFObject::value is updated.
