Jay Berkenbilt 1065bbb016 Handle odd PDFDoc codepoints in UTF-8 during transcoding (fixes #650) 
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.

Jay Berkenbilt 9044a24097 PointerHolder: deprecate getPointer() and getRefcount() 
Use get() and use_count() instead. Add #define
NO_POINTERHOLDER_DEPRECATION to remove deprecation markers for these
only.

This commit also removes all deprecated PointerHolder API calls from
qpdf's code except in PointerHolder's test suite, which must continue
to test the deprecated APIs.

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.

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

are called, but it's worth it to avoid very confusing behavior as
discussed in depth in qpdf#507.

Jay Berkenbilt fc88837d4b Treat /EmbeddedFiles as a proper name tree 
If we ever had an encrypted file with different filters for

attachment streams. The code now properly handles /EmbeddedFiles as a
name tree.

with form XObjects from user code.

Also removes preclusion of stream references in stream parameters of
filterable streams and reduces write times by about 8% by eliminating
an extra traversal of the objects.

Jay Berkenbilt 96767fb104 Fix foreign stream copying bug (fixes #478) 
This reverts an incorrect fix to #449 and codes it properly. The real
problem was that we were looking at the local dictionaries rather than
the foreign dictionaries when saving the foreign stream data. In the
case of direct objects, these happened to be the same, but in the case
of indirect objects, the object references could be pointing anywhere
since object numbers don't match up between the old and new files.

Jay Berkenbilt 4e8d21d849 Build Windows releases with openssl; automate external libraries 
External libraries for Windows are now built automatically in the
qpdf/external-libs repository and include openssl in addition to zlib
and jpeg. Use these, and update the Windows build to build with the
openssl crypto provider by default. We leave the native crypto
provider enabled in case there is a problem with openssl and also to
continue to exercise that code.

of data and/or internal error.
