Jay Berkenbilt 750aca5b94 First increment of improving handling of weak crypto (fixes #358) 2021-11-11 12:24:15 -05:00
Jay Berkenbilt f45dacf4cb Make recovery logic flexible about where objects end (fixes #573)
Don't assume endobj is at the beginning of the line. This means we are
looking at tokens for every line, but the odds of n n obj appearing in
the middle of the object are likely much lower than endobj not being
at the beginning of the line or missing entirely. This will probably
have a negative impact on recovery time for very large files.
Hopefully it will be worth it.

Jay Berkenbilt 4a648b9a00 Fix bug in merging resources /DR from foreign AcroForm (fixes #548)
When making resources indirect in from_dr, the code was using the
wrong owning QPDF, forgetting that from_dr had already been copied
using CopyForeignObject.

Jay Berkenbilt 9b28933647 Check object ownership when adding
When adding a QPDFObjectHandle to an array or dictionary, if possible,
check if the new object belongs to the same QPDF. This makes it much
easier to find incorrect code than waiting for the situation to be
detected when the file is written.

Jay Berkenbilt 33a47d5c3c Make QPDF::findPage public (fixes #516)
This was originally not public because I wanted to get rid fo the
pages cache, but I recently realized there were deep reasons not to do
that, and the author of pikepdf wanted this, so I decided to make it
public.

Jay Berkenbilt e17585c2d2 Remove unreferenced: ignore names that are not Fonts or XObjects
Converted ResourceFinder to ParserCallbacks so we can better detect
the name that precedes various operators and use the operators to sort
the names into resource types. This enables us to be smarter about
detecting unreferenced resources in pages and also sets the stage for
reconciling differences in /DR across documents.

Jay Berkenbilt fa2516df71 Fix behavior for finding /Q, /DA, and /DR for form fields
If not found in the field hierarchy, /Q and /DA are supposed to be
looked up in the document-level form dictionary. /DR is supposed to
only come from the document dictionary.

Jay Berkenbilt a4d6589ff2 Have QPDFObjectHandle notice when replaceObject was called
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.
