2021-12-20Prepare 10.5.0 releaseJay Berkenbilt
2021-11-29Improve testing and error handling around operating before processingJay Berkenbilt
2021-11-29Initialize QPDF::Members::file (fixes #584)Jay Berkenbilt
2021-11-16Prepare 10.4.0 releaserelease-qpdf-10.4.0Jay Berkenbilt
2021-11-07Make recovery logic flexible about where objects end (fixes #573)Jay Berkenbilt
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.

2021-03-05Prepare 10.3.0 releaserelease-qpdf-10.3.0Jay Berkenbilt
2021-03-03Add QPDF::numWarningsJay Berkenbilt
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.
2021-02-23Prepare 10.2.0 releaserelease-qpdf-10.2.0Jay Berkenbilt
2021-02-21QPDFObjectHandle::copyStreamJay Berkenbilt
2021-02-21Refactor: separate copyStreamData from replaceForeignIndirectObjectsJay Berkenbilt
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.
2021-02-06Make wrong object stream type a warningJay 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.
2021-01-24Use new QPDF{Name,Number}TreeObjectHelper APIJay Berkenbilt
2021-01-24Use QPDFNameTreeObjectHelper's iterator directlyJay Berkenbilt
2021-01-11Treat /EmbeddedFiles as a proper name treeJay Berkenbilt
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.
2021-01-06Warn rather than segv on access after closing input source (fixes #495)Jay Berkenbilt
2021-01-04Prepare version 10.1.0release-qpdf-10.1.0Jay Berkenbilt
2020-12-28Implement user-provided stream filtersJay Berkenbilt
Refactor QPDF_Stream to use stream filter classes to handle supported stream filters as well.

2020-11-04Ignore unused field in xref entry, avoiding range error (fixes #482)Jay Berkenbilt
2020-10-31Prepare 10.0.3 releaserelease-qpdf-10.0.3Jay Berkenbilt
2020-10-31Add comments explaining the foreign object copying codeJay Berkenbilt
These are the comments I would have liked to have been able to read while fixing #449 and #478.
2020-10-31Fix foreign stream copying bug (fixes #478)Jay Berkenbilt
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.
2020-10-27Prepare 10.0.2 releaserelease-qpdf-10.0.2Jay Berkenbilt
2020-10-27Revert removal of unreadCh change for performanceJay Berkenbilt
Turns out unreadCh is much more efficient than seek(-1, SEEK_CUR). Update comments and code to reflect this.
2020-10-22Avoid leak by resolving object streams more than once (fuzz issue 23642)Jay Berkenbilt
2020-10-22Minor code cleanupJay Berkenbilt
* Return rather than exiting from realmain in qpdf.cc * Remove extraneous blank line * Don't assign temporary to const reference
2020-10-22Obscure bug fix copying foreign streams in special cases (fixes #449)Jay Berkenbilt
Specifically, if a stream had its stream data replaced and had indirect /Filter or /DecodeParms, it would result in non-silent loss of data and/or internal error.
2020-10-21Protect numeric conversion against user's locale (fixes #459)Jay Berkenbilt
2020-10-18Stop using InputSource::unreadChJay Berkenbilt
2020-10-17Check integer overflow in resolveObjectsInStreamDean Scarff
Fixes a crash found by fuzzing.

2020-04-06Prepare 10.0.0 releaseJay Berkenbilt
2020-04-06Allow propagation of errors and retry through StreamDataProviderJay Berkenbilt
StreamDataProvider::provideStreamData now has a rich enough API for it to effectively proxy to pipeStreamData.
2020-04-04Use deterministic assignments for unique_idDean Scarff
Fixes qpdf/qpdf#419

2019-10-22Add QPDF::getXRefTable()Masamichi Hosoda
2019-10-22Exclude signature dictionary from compressible objectsMasamichi Hosoda
It seems better not to compress signature dictionaries. Various PDF digital signing tools, including Adobe Acrobat Reader DC, do not compress signature dictionaries. Table 8.93 "Entries in a signature dictionary" in PDF 1.5 reference describes that /ByteRange in the signature dictionary shall be used to describe a digest that does not include the signature value (/Contents) itself. The byte ranges cannot be determined if the dictionary is compressed.
