2021-02-25Have QPDFObjectHandle notice when replaceObject was calledJay Berkenbilt
This results in a performance penalty of 1% to 2% when replaceObject and swapObjects are never called and a somewhat larger penalty if they are called, but it's worth it to avoid very confusing behavior as discussed in depth in qpdf#507.

2021-02-06Remove erroneous handling of /EFF for stream decryptionJay Berkenbilt
I thought /EFF was supposed to be used as a default for decrypting embedded file streams, but actually it's supposed to be advice to a conforming writer about handling new ones. This makes sense since the findAttachmentStreams code, which is not actually needed, was never right.
2021-02-03Handle older PDFs whose form XObjects inherit resources (fixes #494)Jay Berkenbilt
When removing unreferenced resources, notice if a page (recursively) contains a form XObject with unreferenced resources, and count any such resources as referenced by the page.
2021-02-03Refactor removal of unreferenced resourcesJay Berkenbilt
Refactor in preparation for resolving unresolved resources in form xobjects from page.
2021-01-31Improve memory safety of dict/array iteratorsJay Berkenbilt

2021-01-26NNTree: rework iterators to be more memory efficientJay Berkenbilt
Keep a std::pair internal to the iterators so that operator* can return a reference and operator-> can work, and each can work without copying pairs of objects around.
2021-01-26name/number trees: removeJay Berkenbilt
2021-01-25name/number trees: insertAfterJay Berkenbilt
2021-01-25name/number trees: newEmpty, increment/decrement end()Jay Berkenbilt

2021-01-24QPDFObjectHandle::newUnicodeString to uses UTF-16 only when neededJay Berkenbilt
Use the first of ASCII, PDFDocEncoding, or UTF-16 that is capable of encoding the string.
2021-01-24Add new constructors for name/number tree helpersJay Berkenbilt
Add constructors that take a QPDF object so we can issue warnings and create new indirect objects.
2021-01-24Use QPDFNameTreeObjectHelper's iterator directlyJay Berkenbilt
2021-01-24Add iterators to name/number tree helpersJay Berkenbilt
2021-01-24Reimplement name and number tree object helpersJay Berkenbilt
Create a computationally and memory efficient implementation of name and number trees that does binary searches as intended by the data structure rather than loading into a map, which can use a great deal of memory and can be very slow.
