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.
 2021-11-04 12:29:42 -04:00
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 73752683c9 Fix overlay/underlay on page with no resources (fixes #527) 2021-11-03 16:00:05 -04:00
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.

Jay Berkenbilt fc88837d4b Treat /EmbeddedFiles as a proper name tree 
If we ever had an encrypted file with different filters for
attachments and either the /EmbeddedFiles name tree was deep or some
of the file specs didn't have /Type, we would have overlooked those as
attachment streams. The code now properly handles /EmbeddedFiles as a
name tree.

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.

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.

Jay Berkenbilt bbc2f8ffae Bug fix: handle ColorSpace lookup for inline images (fixes #392)

page's /Resource -> /ColorSpace dictionary, properly resolve it by
referencing the proper colorspace, and not just the name, in the
external image dictionary.

Jay Berkenbilt 3f1ab64066 Pass offset and length to ParserCallbacks::handleObject 2019-08-22 22:54:29 -04:00
Jay Berkenbilt 4b2e72c4cd Test for direct, rather than resolved nulls in parser 
Just because we know an indirect reference is null, doesn't mean we
shouldn't keep it indirect.
 2019-08-22 17:55:16 -04:00
Jay Berkenbilt 3f3dbe22ea Remove array null flattening 
For some reason, qpdf from the beginning was replacing indirect
references to null with literal null in arrays even after removing the
old behavior of flattening scalar references. This seems like a bad
idea.

Jay Berkenbilt 89dacd8eba Array optimization fixes performance issues (fixes #305, #311) 2019-08-18 09:00:55 -04:00
Thorsten Schöning 8f06da7534 Change list to vector for outline helpers (fixes #297) 
This change works around STL problems with Embarcadero C++ Builder
version 10.2, but std::vector is more common than std::list in qpdf,
and this is a relatively new API, so an API change is tolerable.

Thanks to Thorsten Schöning <6223655+ams-tschoening@users.noreply.github.com>
for the fix.

error-handling code.
 2019-06-22 17:12:01 -04:00
Jay Berkenbilt 6c39aa8763 In shippable code, favor smart pointers (fixes #235) 
Use PointerHolder in several places where manually memory allocation
and deallocation were being used. This helps to protect against memory
leaks when exceptions are thrown in surprising places.

Jay Berkenbilt cc2e8853b5 Enable int warnings by default 
Now that there aren't any more...
 2019-06-21 13:17:21 -04:00
Jay Berkenbilt d71f05ca07 Fix sign and conversion warnings (major) 
This makes all integer type conversions that have potential data loss
explicit with calls that do range checks and raise an exception. After
this commit, qpdf builds with no warnings when -Wsign-conversion
-Wconversion is used with gcc or clang or when -W3 -Wd4800 is used
with MSVC. This significantly reduces the likelihood of potential
crashes from bogus integer values.

There are some parts of the code that take int when they should take
size_t or an offset. Such places would make qpdf not support files
with more than 2^31 of something that usually wouldn't be so large. In
the event that such a file shows up and is valid, at least qpdf would
raise an error in the right spot so the issue could be legitimately
addressed rather than failing in some weird way because of a silent
overflow condition.

Jay Berkenbilt f40ffc9d63 Pl_Flate: constructor's out_bufsize is now unsigned int

Jay Berkenbilt 31bde2f9d7 Handle empty DecodeParams array for (fixes #331) 
On read, ignore /DecodeParms when empty list; on write, delete it.
Some files have been found that include an empty list for
/DecodeParms, but this is not technically compliant with the spec, and
the only sensible interpretation is to treat it as if there are no
decode parameters.

Jay Berkenbilt a5a016cdd2 Revert preservations of outlines with --split-pages 
The preservation of outlines didn't provide very useful behavior
anyway as it copied all outlines but most didn't work. This
implementation also caused a very significant performance hit and so
is being reverted until a proper solution can be coded. The eventual
solution will not be compatible with the reverted solution anyway, so
it's best not to leave this in.
 2019-04-20 21:00:43 -04:00
Jay Berkenbilt da7c2c0ee9 Fix json serialization for {x | -1 < x < 1} (fixes #308) 
JSON serialization was preserving the value as presented, but JSON
doesn't accept decimal values without a 0 before the decimal point.

 2019-01-31 21:29:28 -05:00
Jay Berkenbilt eb49e07c0a Make inline image token exactly contain the image data 
Do not include the trailing EI, and handle cases where EI is not

Jay Berkenbilt 1eb35a355f Exclude space after ID in image data 2019-01-31 10:38:10 -05:00
Jay Berkenbilt 2b6c79bcae Improve locating inline image's EI 
We've actually seen a PDF file in the wild that contained EI
surrounded by delimiters inside the image data, which confused qpdf's
naive code. This significantly improves EI detection.
 2019-01-31 09:26:37 -05:00
Jay Berkenbilt 31372edce0 Inline image token value ends with EI, not delimiter 
The inline image token erroneously included the delimiter that
followed EI. The ObjectHandle created from it was correct.

Jay Berkenbilt 52f9d326a5 Resolve duplicated page objects (fixes #268) 
When linearizing a file or getting the list of all pages in a file,
detect if the pages tree contains a duplicated page object and, if so,
shallow copy it. This makes it possible to have a one to one mapping
of page positions to page objects.
 2019-01-28 20:29:58 -05:00

for text fields, reflect that in the Tf operator used in the
appearance stream.

Jay Berkenbilt 930eade6d3 Fix omissions in text appearance generation
