qpdf: Update to 11.4.0 Changelog: This is qpdf version 11.4.0. This release contains a few minor enhancements and bug fixes. Highlights include improving annotation flattenening to avoid losing annotations in certain technically incorrect but otherwise usable PDF files, and an enhancement to --optimize-images that allows it to traverse into form XObjects. This release also corrects a packaging error that was causing the MinGW DLL to be about 12 times larger than necessary.

qpdf: update to 11.3.0. 11.3.0 This is qpdf version 11.3.0. The main feature of this release is more substantial performance improvements from M. Holger. This release may run as much as 30% faster than 11.2.0 and also uses less RAM. A new flag --remove-restrictions has been added to invalidate digital signatures and associated restrictions to make a signed file editable (invalidating the signature, of course). There are also a few fixes. For a full list of changes from previous releases, please see the release notes. See also README-what-to-download for details about the available source and binary distributions. 11.2.0 This is qpdf version 11.2.0. There are a few bug fixes and minor API enhancements from 11.1.1. This version also fixes a significant performance bug affecting openssl 3.0.x. This bug was causing poor performance with the Windows executables, which should be noticeably faster in this version. 11.1.1 This is qpdf version 11.1.1. This release contains a few minor bug fixes and some performance enhancements. There is no new functionality from 11.1.0. This is the last qpdf release that requires a minimum C++ version of 14. The next release will require a compiler that supports C++-17. 11.1.0 This is qpdf version 11.1.0. This release contains a small number of minor fixes from 11.1, mostly related to build and packaging issues. There are no new features. 11.0.0 This is qpdf version 11.0.0. This is a major release with lots of changes. For a full list of changes from previous releases, please see the release notes. See also README-what-to-download for details about the available source and binary distributions. Here are some release highlights: * qpdf JSON v2 -- a complete, unambiguous representation of PDF file contents using JSON with bidirectional conversion between PDF and JSON * the build now uses cmake * PointerHolder has been replaced by std::shared_ptr * Many performance improvements * Better memory safety for QPDFObjectHandle objects associated with destroyed QPDF objects * A new logging facility that enables more reliable output/error redirection for library users 10.6.3 This is qpdf version 10.6.3. This release contains a few minor bug fixes and some non-functional changes to the build and documentation to help with compiling in other environments. The Windows MSVC releases are now built with Visual Studio 2022.

qpdf: Update to 10.6.2 Changelog: qpdf 10.6.2 This is qpdf version 10.6.2. There are a few more character encoding fixes in this release. A new version of pikepdf is also being released to get them back in sync. qpdf 10.6.1 This is qpdf version 10.6.1. This release fixes a compilation error on some platforms because of a missing header file. qpdf 10.6.0 This is qpdf version 10.6.0. This release includes a few significant changes: * All functionality previously available only from the qpdf CLI has been exposed to the library using a new QPDFJob API, which includes fluent interfaces as well as a JSON format that's equivalent to qpdf's command-line arguments. * Many new interfaces have been added to QPDFObjectHandle and the C API to allow more convient ways querying types and accessing object values in a more type-safe fashion. * qpdf --help has been revamped so that help is divided into categories, and help is available for each option * The Running qpdf section of the manual has been rewritten. The manual now includes an index of command-line arguments. In qpdf 11, PointerHolder will be replaced by std::shared_ptr in QPDF's API. A backward-compatible PointerHolder API will be available. See Smart Pointers for details including things you can do now to prepare. See also comments in PointerHolder.hh.

qpdf: Update to 10.5.0 Changelog: 10.5.0: December 21, 2021 + Packaging changes o Pre-built documentation is no longer distributed with the source distribution. The AppImage and Windows binary distributions still contain embedded documentation, and a separate doc distribution file is available from the qpdf release site. Documentation is now available at https://qpdf.readthedocs.io for every major/minor version starting with version 10.5. Please see Packaging Documentation for details on how packagers should handle documentation. o The documentation sources have been switched from docbook to reStructuredText processed with Sphinx. This will break previous documentation links. A redirect is in place on the main website. A top-to-bottom review of the documentation is planned for an upcoming release. + Library Enhancements o Since qpdf version 8, using object accessor methods on an instance of QPDFObjectHandle may create warnings if the object is not of the expected type. These warnings now have an error code of qpdf_e_object instead of qpdf_e_damaged_pdf. Also, comments have been added to QPDFObjectHandle.hh to explain in more detail what the behavior is. See Object Accessor Methods for a more in-depth discussion. o Add Pl_Buffer::getMallocBuffer() to initialize a buffer allocated with malloc() for better cross-language interoperability. + C API Enhancements o Many thanks to M. Holger whose contributions have heavily influenced these C API enhancements. His several suggestions, pull requests, questions, and critical reading of documentation and comments have resulted in significant usability improvements to the C API. o Overhaul error handling for the object handle functions C API. Some rare error conditions that would previously have caused a crash are now trapped and reported, and the functions that generate them return fallback values. See comments in the ERROR HANDLING section of include/qpdf/qpdf-c.h for details. In particular, exceptions thrown by the underlying C++ code when calling object accessors are caught and converted into errors. The errors can be checked by calling qpdf_has_error. Use qpdf_silence_errors to prevent the error from being written to stderr. o Add qpdf_get_last_string_length to the C API to get the length of the last string that was returned. This is needed to handle strings that contain embedded null characters. o Add qpdf_oh_is_initialized and qpdf_oh_new_uninitialized to the C API to make it possible to work with uninitialized objects. o Add qpdf_oh_new_object to the C API. This allows you to clone an object handle. o Add qpdf_get_object_by_id, qpdf_make_indirect_object, and qpdf_replace_object, exposing the corresponding methods in QPDF and QPDFObjectHandle. o Add several functions for working with pages. See PAGE FUNCTIONS in include/qpdf/qpdf-c.h for details. o Add several functions for working with streams. See STREAM FUNCTIONS in include/qpdf/qpdf-c.h for details. o Add qpdf_oh_get_type_code and qpdf_oh_get_type_name. o Add qpdf_oh_get_binary_string_value and qpdf_oh_new_binary_string for making it easier to deal with strings that contain embedded null characters.

qpdf: Update to 10.4.0 Changelog: 10.4.0: November 16, 2021 + Handling of Weak Cryptography Algorithms o From the qpdf CLI, the --allow-weak-crypto is now required to suppress a warning when explicitly creating PDF files using RC4 encryption. While qpdf will always retain the ability to read and write such files, doing so will require explicit acknowledgment moving forward. For qpdf 10.4, this change only affects the command-line tool. Starting in qpdf 11, there will be small API changes to require explicit acknowledgment in those cases as well. For additional information, see Chapter 6, Weak Cryptography. + Bug Fixes o Fix potential bounds error when handling shell completion that could occur when given bogus input. o Properly handle overlay/underlay on completely empty pages (with no resource dictionary). o Fix crash that could occur under certain conditions when using --pages with files that had form fields. + Library Enhancements o Make QPDF::findPage functions public. o Add methods to Pl_Flate to be able to receive warnings on certain recoverable conditions. o Add an extra check to the library to detect when foreign objects are inserted directly (instead of using QPDF::copyForeignObject) at the time of insertion rather than when the file is written. Catching the error sooner makes it much easier to locate the incorrect code. + CLI Enhancements o Improve diagnostics around parsing --pages command-line options + Packaging Changes o The Windows binary distribution is now built with crypto provided by OpenSSL 3.0.

qpdf: Update to 10.3.1 Changelog: 10.3.1 This is qpdf version 10.3.1. It contains just one bug fix from 10.3.0 which could cause perfectly valid files to fail to go through page splitting if their document-level form dictionary had a particular characteristic. There is also code to better handle future such problems if any are still lurking. 10.3.0 This is qpdf version 10.3.0. This release includes a few minor fixes and some rework of the form field handling code from 10.2.0. It turns out the code in 10.2.0 was not complete and didn't handle several import cases including resolving conflicts when merging the same fields more than once or fields with conflicting names and defaults from multiple files. 10.2.0 This is qpdf version 10.2.0. This release includes several enhancements to the API and CLI including better handling of form fields with page splitting and merging, support for file attachments, an added way to read a password from stdin, several enhancements to form field and annotation helpers, and rewritten support for name and number trees. This release also requires a C++-14 compiler. I have no plans to require anything newer than C++-14 in the foreseeable future. There are also a few bug fixes.

Update to 9.1.0 Changelog: 2019-11-17 Jay Berkenbilt <firstname.lastname@example.org> * 9.1.0: release 2019-11-09 Jay Berkenbilt <email@example.com> * 9.1.rc1: release * Improve behavior of wildcard expansion for msvc executable when run from the Windows cmd.exe shell. Unlike in UNIX environments, Windows leaves it up to the executable to expand its own wildcards. Fixes #224. * When reading /P from the encryption dictionary, use static_cast instead of QIntC to convert the value to a signed integer. The value of /P is a bit field, and PDF files have been found in the wild where /P is represented as an unsigned integer even though the spec states that it is a signed 32-bit value. By using static_cast, we allow qpdf to compensate for writers that incorrectly represent the correct bit field as an unsigned value. Fixes #382. 2019-11-05 Jay Berkenbilt <firstname.lastname@example.org> * Add support for pluggable crypto providers, enabling multiple implementations of the cryptographic functions needed by qpdf. This feature was added by request of Red Hat, which recognized the use of qpdf's native crypto implementations as a potential security liability, preferring instead to get all crypto functionality from a third-party library that receives a lot of scrutiny. However it was also important to me to not impose any unnecessary third party dependencies on my users or packagers, some of which build qpdf for lots of environments, some of which may not easily support gnutls. Starting in qpdf 9.1.0, it is be possible to build qpdf with both the native and gnutls crypto providers or with either in isolation. In support of this feature, new classes QPDFCryptoProvider and QPDFCryptoImpl have been added to the public interface. See QPDFCryptoImpl.hh for details about adding your own crypto provider and QPDFCryptoProvider.hh for details about choosing which one is used. Note that selection of crypto providers is invisible to anyone who doesn't explicitly care. Neither end users nor developers have to be concerned about it. * The environment variable QPDF_CRYPTO_PROVIDER can be used to override qpdf's default choice of crypto provider. The --show-crypto flag to the qpdf CLI can be used to present a list of supported crypto providers with the default provider always listed first. * Add gnutls crypto provider. Thanks to Zdenek Dohnal for contributing the code that I ultimately used in the gnutls crypto provider and for engaging in an extended discussion about this feature. Fixes #218. 2019-10-22 Jay Berkenbilt <email@example.com> * Incorporate changes from Masamichi Hosoda <firstname.lastname@example.org> to properly handle signature in the following ways: - Always represent /Contents in a signature dictionary as a hex string - Do not compress signature dictionaries when generating object streams - Do not encrypt/decrypt the /Contents field of the signature dictionary when creating or reading encrypted files * Incorporate changes from Masamichi Hosoda <email@example.com> to add additional methods for making it possible to gain deeper insight into cross reference tables and object renumbering. These new API calls make it possible for applications to go into PDF files created by qpdf and make changes to them that go beyond working with the PDF at the object level. The specific use case for these changes was to write an external tool to perform digital signature, but there could be other uses as well. New methods include the following, all of which are described in their respective headers: - QPDF::getXRefTable() - QPDFObjectHandle::getParsedOffset() - QPDFWriter::getRenumberedObjGen(QPDFObjGen) - QPDFWriter::getWrittenXRefTable()

Update to 9.0.0 Changelog: 9.0.0: August 31, 2019 Incompatible API (source-level) Changes (minor) The method QUtil::strcasecmp has been renamed to QUtil::str_compare_nocase. This incompatible change is necessary to enable qpdf to build on platforms that define strcasecmp as a macro. The QPDF::copyForeignObject method had an overloaded version that took a boolean parameter that was not used. If you were using this version, just omit the extra parameter. There was a version QPDFTokenizer::expectInlineImage that took no arguments. This version has been removed since it caused the tokenizer to return incorrect inline images. A new version was added some time ago that produces correct output. This is a very low level method that doesn't make sense to call outside of qpdf's lexical engine. There are higher level methods for tokenizing content streams. Change QPDFOutlineDocumentHelper::getTopLevelOutlines and QPDFOutlineObjectHelper::getKids to return a std::vector instead of a std::list of QPDFOutlineObjectHelper objects. Remove method QPDFTokenizer::allowPoundAnywhereInName. This function would allow creation of name tokens whose value would change when unparsed, which is never the correct behavior. When qpdf --check or qpdf --check-linearization encounters a file with linearization warnings but not errors, it now properly exits with exit code 3 instead of 2. CLI Enhancements The --replace-input option may be given in place of an output file name. This causes qpdf to overwrite the input file with the output. See the description of --replace-input in Section 3.3, „ŗ◊£asic Options„ŗfor more details. The --recompress-flate instructs qpdf to recompress streams that are already compressed with /FlateDecode. Useful with --compression-level. The --compression-level=level sets the zlib compression level used for any streams compressed by /FlateDecode. Most effective when combined with --recompress-flate. Library Enhancements A new namespace QIntC, provided by qpdf/QIntC.hh, provides safe conversion methods between different integer types. These conversion methods do range checking to ensure that the cast can be performed with no loss of information. Every use of static_cast in the library was inspected to see if it could use one of these safe converters instead. See Section 7.5, „ŗ◊§asting Policy„ŗfor additional details. Method QPDF::anyWarnings tells whether there have been any warnings without clearing the list of warnings. Method QPDF::closeInputSource closes or otherwise releases the input source. This enables the input file to be deleted or renamed. New methods have been added to QUtil for converting back and forth between strings and unsigned integers: uint_to_string, uint_to_string_base, string_to_uint, and string_to_ull. New methods have been added to QPDFObjectHandle that return the value of Integer objects as int or unsigned int with range checking and sensible fallback values, and a new method was added to return an unsigned value. This makes it easier to write code that is safe from unintentional data loss. Functions: getUIntValue, getIntVauleAsInt, getUIntValueAsUInt. When parsing content streams with QPDFObjectHandle::ParserCallbacks, in place of the method handleObject(QPDFObjectHandle), the developer may override handleObject(QPDFObjectHandle, size_t offset, size_t length). If this method is defined, it will be invoked with the object along with its offset and length within the overall contents being parsed. Intervening spaces and comments are not included in offset and length. Additionally, a new method contentSize(size_t) may be implemented. If present, it will be called prior to the first call to handleObject with the total size in bytes of the combined contents. New methods QPDF::userPasswordMatched and QPDF::ownerPasswordMatched have been added to enable a caller to determine whether the supplied password was the user password, the owner password, or both. This information is also displayed by qpdf --show-encryption and qpdf --check. Static method Pl_Flate::setCompressionLevel can be called to set the zlib compression level globally used by all instances of Pl_Flate in deflate mode. The method QPDFWriter::setRecompressFlate can be called to tell QPDFWriter to uncompress and recompress streams already compressed with /FlateDecode. The underlying implementation of QPDF arrays has been enhanced to be much more memory efficient when dealing with arrays with lots of nulls. This enables qpdf to use drastically less memory for certain types of files. When traversing the pages tree, if nodes are encountered with invalid types, the types are fixed, and a warning is issued. A new helper method QUtil::read_file_into_memory was added. All conditions previously reported by QPDF::checkLinearization() as errors are now presented as warnings. Name tokens containing the # character not preceded by two hexadecimal digits, which is invalid in PDF 1.2 and above, are properly handled by the library: a warning is generated, and the name token is properly preserved, even if invalid, in the output. See ChangeLog for a more complete description of this change. Bug Fixes A small handful of memory issues, assertion failures, and unhandled exceptions that could occur on badly mangled input files have been fixed. Most of these problems were found by Google's OSS-Fuzz project. When qpdf --check or qpdf --check-linearization encounters a file with linearization warnings but not errors, it now properly exits with exit code 3 instead of 2. The --completion-bash and --completion-zsh options now work properly when qpdf is invoked as an AppImage. Calling QPDFWriter::set*EncryptionParameters on a QPDFWriter object whose output filename has not yet been set no longer produces a segmentation fault. When reading encrypted files, follow the spec more closely regarding encryption key length. This allows qpdf to open encrypted files in most cases when they have invalid or missing /Length keys in the encryption dictionary. When qpdf --check or qpdf --check-linearization encounters a file with linearization warnings but not errors, it now properly exits with exit code 3 instead of 2. Build Changes On platforms that support it, qpdf now builds with -fvisibility=hidden. If you build qpdf with your own build system, this is now safe to use. This prevents methods that are not part of the public API from being exported by the shared library, and makes qpdf's ELF shared libraries (used on Linux, MacOS, and most other UNIX flavors) behave more like the Windows DLL. Since the DLL already behaves in much this way, it is unlikely that there are any methods that were accidentally not exported. However, with ELF shared libraries, typeinfo for some classes has to be explicitly exported. If there are problems in dynamically linked code catching exceptions or subclassing, this could be the reason. If you see this, please report a bug at pikepdf. QPDF is now compiled with integer conversion and sign conversion warnings enabled. Numerous changes were made to the library to make this safe. QPDF's make install target explicitly specifies the mode to use when installing files instead of relying the user's umask. It was previously doing this for some files but not others. If pkg-config is available, use it to locate libjpeg and zlib dependencies, falling back on old behavior if unsuccessful. Other Notes QPDF has been fully integrated into Google's OSS-Fuzz project. This project exercises code with randomly mutated inputs and is great for discovering hidden security crashes and security issues. Several bugs found by oss-fuzz have already been fixed in qpdf.

Update to 8.3.0 Changelog: 2019-01-07 Jay Berkenbilt <firstname.lastname@example.org> * 8.3.0: release * Add sample completion files in completions. These can be used by packagers to install on the system wherever bash and zsh keep their vendor-supplied completions. * Add configure flag --enable-check-autofiles, which is on by default. Packagers whose packaging systems automatically refresh autoconf or libtool files should pass --disable-check-autofiles to ./configure to suppress warnings about automatically generated files being outdated. 2019-01-06 Jay Berkenbilt <email@example.com> * Remove the restriction in most cases that the source QPDF used in a copyForeignObject call has to stick around until the destination QPDF is written. The exceptional case is when the source stream gets is data using a QPDFObjectHandle::StreamDataProvider. For a more in-depth discussion, see comments around copyForeignObject in QPDF.hh. Fixes #219. 2019-01-05 Jay Berkenbilt <firstname.lastname@example.org> * When generating appearances, if the font uses one of the standard, built-in encodings, restrict the character set to that rather than just to ASCII. This will allow most appearances to contain characters from the ISO-Latin-1 range plus a few additional characters. * Add methods QUtil::utf8_to_win_ansi and QUtil::utf8_to_mac_roman. * Add method QUtil::utf8_to_utf16. 2019-01-04 Jay Berkenbilt <email@example.com> * Add new option --optimize-images, which recompresses every image using DCT (JPEG) compression as long as the image is not already compressed with lossy compression and recompressing the image reduces its size. The additional options --oi-min-width, --oi-min-height, and --oi-min-area prevent recompression of images whose width, height, or pixel area (width * height) are below a specified threshold. * Add new option --collate. When specified, the semantics of --pages change from concatenation to collation. See the manual for a more detailed discussion. Fixes #259. * Add new method QPDFWriter::getFinalVersion, which returns the PDF version that will ultimately be written to the final file. See comments in QPDFWriter.hh for some restrictions on its use. Fixes #266. * When unexpected errors are found while checking linearization data, print an error message instead of calling assert, which cause the program to crash. Fixes #209, #231. * Detect and recover from dangling references. If a PDF file contained an indirect reference to a non-existent object (which is valid), when adding a new object to the file, it was possible for the new object to take the object ID of the dangling reference, thereby causing the dangling reference to point to the new object. This case is now prevented. Fixes #240. 2019-01-03 Jay Berkenbilt <firstname.lastname@example.org> * Add --generate-appearances flag to the qpdf command-line tool to trigger generation of appearance streams. * Fix behavior of form field value setting to handle the following cases: - Strings are always written as UTF-16 - Check boxes and radio buttons are handled properly with synchronization of values and appearance states * Define constants in qpdf/Constants.h for interpretation of annotation and form field flags * Add QPDFAnnotationObjectHelper::getFlags * Add many new methods to QPDFFormFieldObjectHelper for querying flags and field types * Add new methods for appearance stream generation. See comments in QPDFFormFieldObjectHelper.hh for generateAppearance() for a description of limitations. - QPDFAcroFormDocumentHelper::generateAppearancesIfNeeded - QPDFFormFieldObjectHelper::generateAppearance * Bug fix: when writing form field values, always write string values encoded as UTF-16. * Add method QUtil::utf8_to_ascii, which returns an ASCII string for a UTF-8 string, replacing out-of-range characters with a specified substitute. 2019-01-02 Jay Berkenbilt <email@example.com> * Add method QPDFObjectHandle::getResourceNames that returns a set of strings representing all second-level keys in a dictionary (i.e. all keys of all direct dictionary members). 2018-12-31 Jay Berkenbilt <firstname.lastname@example.org> * Add --flatten-annotations flag to the qpdf command-line tool for annotation flattening. * Add methods for flattening form fields and annotations: - QPDFPageDocumentHelper::flattenAnnotations - integrate annotation appearance streams into page contents with special handling for form fields: if appearance streams are up to date (/NeedAppearances is false in /AcroForm), the /AcroForm key of the document catalog is removed. Otherwise, a warning is issued, and form fields are ignored. Non-form-field annotations are always flattened if an appearance stream can be found. - QPDFAnnotationObjectHelper::getPageContentForAppearance - generate the content stream fragment to render an appearance stream in a page's content stream as a form xobject. Called by flattenAnnotations. * Add method QPDFObjectHandle::mergeResources(), which merges resource dictionaries. See detailed description in QPDFObjectHandle.hh. * Add QPDFObjectHandle::Matrix, similar to QPDFObjectHandle::Rectangle, as a convenience class for six-element arrays that are used as matrices. 2018-12-23 Jay Berkenbilt <email@example.com> * When specifying @arg on the command line, if the file "arg" does not exist, just treat this is a normal argument. This makes it easier to deal with files whose names start with the @ character. Fixes #265. * Tweak completion so it works with zsh as well using bashcompinit. 2018-12-22 Jay Berkenbilt <firstname.lastname@example.org> * Add new options --json, --json-key, and --json-object to generate a json representation of the PDF file. This is described in more depth in the manual. You can also run qpdf --json-help to get a description of the json format. 2018-12-21 Jay Berkenbilt <email@example.com> * Allow --show-object=trailer for showing the document trailer. * You can now use eval $(qpdf --completion-bash) to enable bash completion for qpdf. It's not perfect, but it works pretty well. 2018-12-19 Jay Berkenbilt <firstname.lastname@example.org> * When splitting pages using --split-pages, the outlines dictionary and some supporting metadata are copied into the split files. The result is that all bookmarks from the original file appear, and those that point to pages that are preserved work while those that point to pages that are not preserved don't do anything. This is an interim step toward proper support for bookmark preservation in split files. * Add QPDFOutlineDocumentHelper and QPDFOutlineObjectHelper for handling outlines (bookmarks) including bidirectionally mapping between bookmarks and pages. Initially there is no support for modifying the outlines hierarchy. 2018-12-18 Jay Berkenbilt <email@example.com> * New method QPDFObjectHandle::getJSON() returns a JSON object with a partial representation of the object. See QPDFObjectHandle.hh for a detailed description. * Add a simple JSON serializer. This is not a complete or general-purpose JSON library. It allows assembly and serialization of JSON structures with some restrictions, which are described in the header file. * Add QPDFNameTreeObjectHelper class. This class provides useful methods for dealing with name trees, which are discussed in section 7.9.6 of the PDF spec (ISO-32000). * Preserve page labels when merging and splitting files. Prior versions of qpdf simply preserved the page label information from the first file, which usually wouldn't make any sense in the merged file. Now any page that had a page number in any original file will have the same page number after merging or splitting. * Add QPDFPageLabelDocumentHelper class. This is a document helper class that provides useful methods for dealing with page labels. It abstracts the fact that they are stored as number trees and deals with interpolating intermediate values that are not in the tree. It also has helper functions used by the qpdf command line tool to preserve page labels when merging and splitting files. * Add QPDFNumberTreeObjectHelper class. This class provides useful methods for dealing with number trees, which are discussed in section 7.9.7 of the PDF spec (ISO-32000). Page label dictionaries are represented as number trees. * New method QPDFObjectHandle::wrapInArray returns the object itself if it is an array. Otherwise, it returns an array containing the object. This is useful for dealing with PDF data that is sometimes expressed as a single element and sometimes expressed as an array, which is a somewhat common PDF idiom. 2018-10-11 Jay Berkenbilt <firstname.lastname@example.org> * Files generated by autogen.sh are now committed so that it is possible to build on platforms without autoconf directly from a clean checkout of the repository. The configure script detects if the files are out of date when it also determines that the tools are present to regenerate them. * Add build in Azure Pipelines, now that it is free for open source projects.

Update to 8.1.0 Changelog: 8.1.0: June 23, 2018 Usability Improvements When splitting files, qpdf detects fonts and images that the document metadata claims are referenced from a page but are not actually referenced and omits them from the output file. This change can cause a significant reduction in the size of split PDF files for files created by some software packages. Prior versions of qpdf would believe the document metadata and sometimes include all the images from all the other pages even though the pages were no longer present. In the unlikely event that the old behavior should be desired, it can be enabled by specifying --preserve-unreferenced-resources. For additional details, please see Section 3.6, „ŗ◊Ędvanced Transformation Options„ŗ When merging multiple PDF files, qpdf no longer leaves all the files open. This makes it possible to merge numbers of files that may exceed the operating system's limit for the maximum number of open files. The --rotate option's syntax has been extended to make the page range optional. If you specify --rotate=angle without specifying a page range, the rotation will be applied to all pages. This can be especially useful for adjusting a PDF created from a multi-page document that was scanned upside down. When merging multiple files, the --verbose option now prints information about each file as it operates on that file. When the --progress option is specified, qpdf will print a running indicator of its best guess at how far through the writing process it is. Note that, as with all progress meters, it's an approximation. This option is implemented in a way that makes it useful for software that uses the qpdf library; see API Enhancements below. Bug Fixes Properly decrypt files that use revision 3 of the standard security handler but use 40 bit keys (even though revision 3 supports 128-bit keys). Limit depth of nested data structures to prevent crashes from certain types of malformed (malicious) PDFs. In „ŗ◊Ōewline before endstream„ŗmode, insert the required extra newline before the endstream at the end of object streams. This one case was previously omitted. API Enhancements The first round of higher level „ŗ◊…elper„ŗinterfaces has been introduced. These are designed to provide a more convenient way of interacting with certain document features than using QPDFObjectHandle directly. For details on helpers, see Section 6.3, „ŗ◊©elper Classes„ŗ Specific additional interfaces are described below. Add two new document helper classes: QPDFPageDocumentHelper for working with pages, and QPDFAcroFormDocumentHelper for working with interactive forms. No old methods have been removed, but QPDFPageDocumentHelper is now the preferred way to perform operations on pages rather than calling the old methods in QPDFObjectHandle and QPDF directly. Comments in the header files direct you to the new interfaces. Please see the header files and ChangeLog for additional details. Add three new object helper class: QPDFPageObjectHelper for pages, QPDFFormFieldObjectHelper for interactive form fields, and QPDFAnnotationObjectHelper for annotations. All three classes are fairly sparse at the moment, but they have some useful, basic functionality. A new example program examples/pdf-set-form-values.cc has been added that illustrates use of the new document and object helpers. The method QPDFWriter::registerProgressReporter has been added. This method allows you to register a function that is called by QPDFWriter to update your idea of the percentage it thinks it is through writing its output. Client programs can use this to implement reasonably accurate progress meters. The qpdf command line tool uses this to implement its --progress option. New methods QPDFObjectHandle::newUnicodeString and QPDFObject::unparseBinary have been added to allow for more convenient creation of strings that are explicitly encoded using big-endian UTF-16. This is useful for creating strings that appear outside of content streams, such as labels, form fields, outlines, document metadata, etc. A new class QPDFObjectHandle::Rectangle has been added to ease working with PDF rectangles, which are just arrays of four numeric values.

Update to 8.0.2 Changelog: 8.0.2: Version 8.0.2 contains two small bug fixes: proper handling of pages with no content, and better handling of files with loops following cross reference tables. 8.0.1: This is a very minor update from 8.0.0. It just contains two small enhancements that missed the train: handle zlib streams with data checksum errors, and, in the command line tool, allow specification of page numbers counting from the end in page ranges.

Update to 8.0.0 Changelog: 2018-02-25 Jay Berkenbilt <email@example.com> * 8.0.0: release 2018-02-17 Jay Berkenbilt <firstname.lastname@example.org> * Fix QPDFObjectHandle::getUTF8Val() to properly handle strings that are encoded with PDF Doc Encoding. Fixes #179. * Add qpdf_check_pdf to the "C" API. This method just attempts to read the entire file and produce no output, making possible to assess whether the file has any errors that qpdf can detect. * Major enhancements to handling of type errors within the qpdf library. This fix is intended to eliminate those annoying cases where qpdf would exit with a message like "operation for dictionary object attemped on object of wrong type" without providing any context. Now qpdf keeps enough context to be able to issue a proper warning and to handle such conditions in a sensible way. This should greatly increase the number of bad files that qpdf can recover, and it should make it much easier to figure out what's broken when a file contains errors. * Error message fix: replace "file position" with "offset" in error messages that report lexical or parsing errors. Sometimes it's an offset in an object stream or a content stream rather than a file position, so this makes the error message less confusing in those cases. It still requires some knowledge to find the exact position of the error, since when it's not a file offset, it's probably an offset into a stream after uncompressing it. * Error message fix: correct some cases in which the object that contained a lexical error was omitted from the error message. * Error message fix: improve file name in the error message when there is a parser error inside an object stream. 2018-02-11 Jay Berkenbilt <email@example.com> * Add QPDFObjectHandle::filterPageContents method to provide a different interface for applying token filters to page contents without modifying the ultimate output. 2018-02-04 Jay Berkenbilt <firstname.lastname@example.org> * Changes listed on today's date are numerous and reflect significant enhancements to qpdf's lexical layer. While many nuances are discussed and a handful of small bugs were fixed, it should be emphasized that none of these issues have any impact on any output or behavior of qpdf under "normal" operation. There are some changes that have an effect on content stream normalization as with qdf mode or on code that interacts with PDF files lexically using QPDFTokenizer. There are no incompatible changes for normal operation. There are a few changes that will affect the exact error messages issued on certain bad files, and there is a small non-compatible enhancement regarding the behavior of manually constructed QPDFTokenizer::Token objects. Users of the qpdf command line tool will see no changes other than the addition of a new command-line flag and possibly some improved error messages. * Significant lexer (tokenizer) enhancements. These are changes to the QPDFTokenizer class. These changes are of concern only to people who are operating with PDF files at the lexical layer using qpdf. They have little or no impact on most high-level interfaces or the command-line tool. New token types tt_space and tt_comment to recognize whitespace and comments. this makes it possible to tokenize a PDF file or stream and preserve everything about it. For backward compatibility, space and comment tokens are not returned by the tokenizer unless QPDFTokenizer.includeIgnorable() is called. Better handling of null bytes. These are now included in space tokens rather than being their own "tt_word" tokens. This should have no impact on any correct PDF file and has no impact on output, but it may change offsets in some error messages when trying to parse contents of bad files. Under default operation, qpdf does not attempt to parse content streams, so this change is mostly invisible. Bug fix to handling of bad tokens at ends of streams. Now, when allowEOF() has been called, these are treated as bad tokens (tt_bad or an exception, depending on invocation), and a separate tt_eof token is returned. Before the bad token contents were returned as the value of a tt_eof token. tt_eof tokens are always empty now. Fix a bug that would, on rare occasions, report the offset in an error message in the wrong space because of spaces or comments adjacent to a bad token. Clarify in comments exactly where the input source is positioned surrounding calls to readToken and getToken. * Add a new token type for inline images. This token type is only returned by QPDFTokenizer immediately following a call to expectInlineImage(). This change includes internal refactoring of a handful of places that all separately handled inline images, The logic of detecting inline images in content streams is now handled in one place in the code. Also we are more flexible about what characters may surround the EI operator that marks the end of an inline image. * New method QPDFObjectHandle::parsePageContents() to improve upon QPDFObjectHandle::parseContentStream(). The parseContentStream method used to operate on a single content stream, but was fixed to properly handle pages with contents split across multiple streams in an earlier release. The new method parsePageContents() can be called on the page object rather than the value of the page dictionary's /Contents key. This removes a few lines of boiler-plate code from any code that uses parseContentStream, and it also enables creation of more helpful error messages if problems are encountered as the error messages can include information about which page the streams come from. * Update content stream parsing example (examples/pdf-parse-content.cc) to use new QPDFObjectHandle::parsePageContents() method in favor of the older QPDFObjectHandle::parseContentStream() method. * Bug fix: change where the trailing newline is added to a stream in QDF mode when content normalization is enabled (the default for QDF mode). Before, the content normalizer ensured that the output ended with a trailing newline, but this had the undesired side effect of including the newline in the stream data for purposes of length computation. QPDFWriter already appends a newline without counting in length for better readability. Ordinarily this makes no difference, but in the rare case of a page's contents being split in the middle of a token, the old behavior could cause the extra newline to be interprted as part of the token. This bug could only be triggered in qdf mode, which is a mode intended for manual inspection of PDF files' contents, so it is very unlikely to have caused any actual problems for people using qpdf for production use. Even if it did, it would be very unusual for a PDF file to actually be adversely affected by this issue. * Add support for coalescing a page's contents into a single stream if they are represented as an array of streams. This can be performed from the command line using the --coalesce-contents option. Coalescing content streams can simplify things for software that wants to operate on a page's content streams without having to handle weird edge cases like content streams split in the middle of tokens. Note that QPDFObjectHandle::parsePageContents and QPDFObjectHandle::parseContentStream already handled split content streams. This is mainly to set the stage for new methods of operating on page contents. The new method QPDFObjectHandle::pipeContentStreams will pipe all of a page's content streams though a single pipeline. The new method QPDFObjectHandle.coalesceContentStreams, when called on a page object, will do nothing if the page's contents are a single stream, but if they are an array of streams, it will replace the page's contents with a single stream whose contents are the concatenation of the original streams. * A few library routines throw exceptions if called on non-page objects. These constraints have been relaxed somewhat to make qpdf more tolerant of files whose page dictionaries are not properly marked as such. Mostly exceptions about page operations being called on non page objects will only be thrown in cases where the operation had no chance of succeeding anyway. This change has no impact on any default mode operations, but it could allow applications that use page-level APIs in QPDFObjectHandle to be more tolerant of certain types of damaged files. * Add QPDFObjectHandle::TokenFilter class and methods to use it to perform lexical filtering on content streams. You can call QPDFObjectHandle::addTokenFilter on stream object, or you can call the higher level QPDFObjectHandle::addContentTokenFilter on a page object to cause the stream's contents to passed through a token filter while being retrieved by QPDFWriter or any other consumer. For details on using TokenFilter, please see comments in QPDFObjectHandle.hh. * Enhance the string, type QPDFTokenizer::Token constructor to initialize a raw value in addition to a value. Tokens have a value, which is a canonical representation, and a raw value. For all tokens except strings and names, the raw value and the value are the same. For strings, the value excludes the outer delimiters and has non-printing characters normalized. For names, the value resolves non-printing characters. In order to better facilitate token filters that mostly preserve contents and to enable developers to be mostly unconcerned about the nuances of token values and raw values, creating string and name tokens now properly handles this subtlety of values and raw values. When constructing string tokens, take care to avoid passing in the outer delimiters. This has always been the case, but it is now clarified in comments in QPDFObjectHandle.hh::TokenFilter. This has no impact on any existing code unless there's some code somewhere that was relying on Token::getRawValue() returning an empty string for a manually constructed token. The token class's operator== method still only looks at type and value, not raw value. For example, string tokens for <41> and (A) would still be equal because both are representations of the string "A". * Add QPDFObjectHandle::isDataModified method. This method just returns true if addTokenFilter has been called on the stream. It enables a caller to determine whether it is safe to optimize away piping of stream data in cases where the input and output are expected to be the same. QPDFWriter uses this internally to skip the optimization of not re-compressing already compressed streams if addTokenFilter has been called. Most developers will not have to worry about this as it is used internally in the library in the places that need it. If you are manually retrieving stream data with QPDFObjectHandle::getStreamData or QPDFObjectHandle::pipeStreamData, you don't need to worry about this at all. * Provide heavily annoated examples/pdf-filter-tokens.cc example that illustrates use of some simple token filters. * When normalizing content streams, as in qdf mode, issue warning about bad tokens. Content streams are only normalized when this is explicitly requested, so this has no impact on normal operation. However, in qdf mode, if qpdf detects a bad token, it means that either there's a bug in qpdf's lexer, that the file is damaged, or that the page's contents are split in a weird way. In any of those cases, qpdf could potentially damage the stream's contents by replacing carrige returns with newlines or otherwise messing with spaces. The mostly likely case of this would be an inline image's compressed data being divided across two streams and having the compressed data in the second stream contain a carriage return as part of its binary data. If you are using qdf mode just to look at PDF files in text editors, this usually doesn't matter. In cases of contents split across multiple streams, coalescing streams would eliminate the problem, so the warning mentions this. Prior to this enhancement, the chances of qdf mode writing incorrect data were already very low. This change should make it nearly impossible for qdf mode to unknowingly write invalid data. 2018-02-04 Jay Berkenbilt <email@example.com> * Add QPDFWriter::setLinearizationPass1Filename method and --linearize-pass1 command line option to allow specification of a file into which QPDFWriter will write its intermediate linearization pass 1 file. This is useful only for debugging qpdf. qpdf creates linearized files by computing the output in two passes. Ordinarily the first pass is discarded and not written anywhere.

Update to 7.1.0 Changelog: 2018-01-14 Jay Berkenbilt <firstname.lastname@example.org> * 7.1.0: release * Allow raw encryption key to be specified in libary and command line with the QPDF::setPasswordIsHexKey method and --password-is-hex-key option. Allow encryption key to be displayed with --show-encryption-key option. Thanks to Didier Stevens <email@example.com> for the idea and contribution of one implementation of this idea. See his blog post at https://blog.didierstevens.com/2017/12/28/cracking-encrypted-pdfs-part-3/ for a discussion of using this for cracking encrypted PDFs. I hope that a future release of qpdf will include some additional recovery options that may also make use of this capability. 2018-01-13 Jay Berkenbilt <firstname.lastname@example.org> * Fix lexical error: the PDF specification allows floating point numbers to end with ".". Fixes #165. * Fix link order in the build to avoid conflicts when building from source while an older version of qpdf is installed. Fixes #158. * Add support for TIFF predictor for LZW and Flate streams. Now all predictor functions are supported. Fixes #171. 2017-12-25 Jay Berkenbilt <email@example.com> * Clarify documentation around options that control parsing but not output creation. Two options: --suppress-recovery and --ignore-xref-streams, were documented in the "Advanced Transformation Options" section of the manual and --help output even though they are not related to output. These are now described in a separate section called "Advanced Parsing Options." * Implement remaining PNG filters for decode. Prior versions could decode only the "up" filter. Now all PNG filters (sub, up, average, Paeth, optimal) are supported for decoding. Thanks to Tobias Hoffmann for providing a test PDF file that has images with all PNG filters along with different numbers of bits per sample and samples per pixel, and thanks to Casey Rojas for providing implementations of the remaining PNG filters. The implementation of the remaining PNG filters changed the interface to the private Pl_PNGFilter class, but this class's header file is not in the installation, and there is no public interface to the class. Within the library, the class is never allocated on the stack; it is only ever dynamically allocated. As such, this does not actually break binary compatibility of the library.

Update to 7.0.0 Changelog: 2017-09-15 Jay Berkenbilt <firstname.lastname@example.org> * 7.0.0: release 2017-09-12 Jay Berkenbilt <email@example.com> * Relicense qpdf under version 2.0 of the Apache License rather than version 2.0 of the Artistic License. Both are fine, but the Apache License is in more widespread use, and I like it a little better than Artistic-2.0. It is my intention that there be no change in what you can or can't do with qpdf. Versions of qpdf prior to version 7 were released under the terms of version 2.0 of the Artistic License. At your option, you may continue to consider qpdf to be licensed under those terms. Please see the manual for additional information. * Improve the error message that is issued when QPDFWriter encounters a stream that can't be decoded. In particular, mention that the stream will be copied without filtering to avoid data loss. * Add new methods to the C API to correspond to new additions to QPDFWriter: - qpdf_set_compress_streams - qpdf_set_decode_level - qpdf_set_preserve_unreferenced_objects - qpdf_set_newline_before_endstream 2017-08-25 Jay Berkenbilt <firstname.lastname@example.org> * Re-implement parser iteratively to avoid stack overflow on very deeply nested arrays and dictionaries. Fixes #146. * Detect infinite loop while finding additional xref tables. Fixes #149. 2017-08-22 Jay Berkenbilt <email@example.com> * 7.0.b1: release * Convert all README files to markdown. Names changed as follows: - README --> README.md - README.hardening --> README-hardening.md - README.maintainer --> README-maintainer.md - README-what-to-download.txt --> README-what-to-download.md - README-windows.txt --> README-windows.md The file README-windows-install.txt remains a text file. 2017-08-21 Jay Berkenbilt <firstname.lastname@example.org> * Add support for writing PCLm files. Most of the work was done by Sahil Arora <email@example.com> as part of a Google Summer of Code project in 2017. PCLm support is useful only for clients that specifically know how to create PCLm files. Support in qpdf is just for ensuring that objects are written in the correct order and for including some additional material in the output that is required by the PCLm standard. 2017-08-19 Jay Berkenbilt <firstname.lastname@example.org> * Remove --precheck-streams. This is enabled by default now without any efficiency cost. This feature was never released. * Update pdf-create example to illustrate use of additional image compression filters. * Add support for /RunLengthDecode and /DCTDecode: - New pipeline types Pl_RunLength and Pl_DCT - New command-line flags --compress-streams and --decode-level to replace/enhance --stream-data - New QPDFWriter::setCompressStreams and QPDFWriter::setDecodeLevel methods Please see documentation, header files, and help messages for details on these new features. 2017-08-12 Jay Berkenbilt <email@example.com> * Add QPDFObjectHandle::rotatePage to apply rotation to a page object. Add --rotate option to qpdf to specify page rotation from the command line. * Provide --verbose option that causes qpdf to print an indication of what files it is writing. * Change --single-pages to --split-pages and make it take an optional argument specifying the number of pages per file. 2017-08-11 Jay Berkenbilt <firstname.lastname@example.org> * Fix --newline-before-endstream to always add a newline before endstream even if the last character was already a newline. This is actually what's required by PDF/A. Fixes #133. * Handle encrypted files whose encryption parameters are too short. Fixes #96. 2017-08-10 Jay Berkenbilt <email@example.com> * Remove dependency on libpcre. * Be more forgiving of certain types of errors in the xref table that don't interfere with interpreting the table. * Remove unused "tracing" parameter from PointerHolder's (T*, bool) constructor. This change breaks source code compatibility, but since this argument to PointerHolder has not used for a long time and the presence of a boolean parameter in the primary constructor makes it too easy to use that by mistake when trying to use PointerHolder for arrays, it seems like it's finally time to take it out. If you have a compile error because of this change, please check to see whether you intended to use the (bool, T*) version of the constructor instead. If not, just remove the second parameter. 2017-08-09 Jay Berkenbilt <firstname.lastname@example.org> * When recovering stream length, find endobj without endstream as well as just looking for endstream. Be a little more lax about where we allow it to be found. 2017-08-05 Jay Berkenbilt <email@example.com> * Add --single-pages option to cause output to be written to a separate file for each page rather than one big file. * Process --pages options earlier so that certain inspection options, like --show-pages, can show the state after the merging operations. 2017-08-02 Jay Berkenbilt <firstname.lastname@example.org> * Fix off-by-one error in parsing pages options. Fixes #129. 2017-07-29 Jay Berkenbilt <email@example.com> * Support @filename and @- in the qpdf command-line tool to read command-line arguments, one per line, from the named file. @- reads from standard input. Fixes #16. * Detect when input file and output file are the same and exit to avoid overwriting and losing input file. Fixes #29. * When passing multiple inspection arguments, run --check first, and defer exit until after all the checks have been run. This makes it possible to force operations such as --show-xref to be delayed until after recovery attempts have been made. For example, if you have a file with a syntactically valid xref table that has some offsets that are incorrect, running qpdf --check --show-xref on that file will first recover the xref and the dump the recovered xref, while just running qpdf --show-xref will show the xref table as present in the file. Fixes #42. * When recovering stream length, indicate the recovered length. Fixes #44. * Add --newline-before-endstream command-line option and setNewlineBeforeEndstream method to QPDFWriter. This forces qpdf to always add a newline before the endstream keyword. It is a necessary but not sufficient condition for PDF/A compliance. Fixes #103. * Handle zlib data errors when decoding streams. Fixes #106. * Improve handling of files where the "stream" keyword is not followed by proper line terminators. Fixes #104. * Fix content stream parsing to handle cases of structures within the stream split across stream boundaries. Fixes #73. 2017-07-28 Jay Berkenbilt <firstname.lastname@example.org> * Add --preserve-unreferenced command-line option and setPreserveUnreferencedObjects method to QPDFWriter. This option causes QPDFWriter to write all objects from the input file to the output file regardless of whether the objects are referenced. Objects are written to the output file in numerical order from the input file. This option has no effect for linearized files. 2017-07-27 Jay Berkenbilt <email@example.com> * Add --precheck-streams command-line option and setStreamPrecheck method to QPDFWriter to tell QPDFWriter to attempt decoding a stream fully before deciding whether to filter it or not. * Recover gracefully from streams that aren't filterable because the filter parameters are invalid in the stream dictionary or the dictionary itself is invalid. * Significantly improve recoverability from invalid qpdf objects. Most conditions in basic object parsing that used to cause qpdf to exit are now warnings. There are still many more opportunities for improvements of this sort beyond just object parsing. 2017-07-26 Jay Berkenbilt <firstname.lastname@example.org> * Fixes to infinite loops below also fix problems reported in other issues and cover CVE-2017-11624, CVE-2017-11625, CVE-2017-11626, and CVE-2017-11627. * Don't attempt to interpret syntactic keywords (like R and endobj) found while parsing content streams. * Detect infinite loops while resolving objects. This could happen if something inside an object that had to be resolved during parsing, such as a stream length, recursively referenced the object being resolved. * CVE-2017-9208: Handle references to and appearance of object 0 as a special case. Object 0 is not allowed, and qpdf was using it internally to represent direct objects. * CVE-2017-9209: Fix infinite loop caused by attempting to reconstruct the xref table while already in the process of reconstructing the xref table. * CVE-2017-9210: Fix infinite loop caused by attempting to unparse an object for inclusion in the text of an exception.

Update 5.0.1 to 5.1.2 --------------------- 2014-06-07 Jay Berkenbilt <email@example.com> * 5.1.2: release * MS Visual C++ build: explicitly target Windows 5.0.1 (XP) * New example program: pdf-split-pages: efficiently split PDF files into individual pages. * Bug fix: don't fail on files that contain streams where /Filter or /DecodeParms references a stream. Before, qpdf would try to convert these to direct objects, which would fail because of the stream. 2014-02-22 Jay Berkenbilt <firstname.lastname@example.org> * Bug fix: if the last object in the first part of a linearized file had an offset that was below 65536 by less than the size of the hint stream, the xref stream was invalid and the resulting file is not usable. This is now fixed. 2014-01-14 Jay Berkenbilt <email@example.com> * 5.1.1: release 2013-12-26 Jay Berkenbilt <firstname.lastname@example.org> * Bug fix: when copying foreign objects (which occurs during page splitting among other cases), avoid traversing the same object more than once if it appears more than once in the same direct object. This bug is performance-only and does not affect the actual output. 2013-12-17 Jay Berkenbilt <email@example.com> * 5.1.0: release 2013-12-16 Jay Berkenbilt <firstname.lastname@example.org> * Document and make explicit that passing null to QUtil::setRandomDataProvider() resets the random data provider. * Provide QUtil::getRandomDataProvider(). 2013-12-14 Jay Berkenbilt <email@example.com> * Allow anyspace rather than just newline to follow xref header. This allows qpdf to read a wider range of damaged files. 2013-11-30 Jay Berkenbilt <firstname.lastname@example.org> * Allow user-supplied random data provider to be used in place of OS-provided or insecure random number generation. See documentation for 5.1.0 for details. * Add configure option --enable-os-secure-random (enabled by default). Pass --disable-os-secure-random or define SKIP_OS_SECURE_RANDOM to avoid attempts to use the operating system-provided secure random number generation. This can be especially useful on Windows if you wish to avoid any dependency on Microsoft's cryptography system. 2013-11-29 Jay Berkenbilt <email@example.com> * If NO_GET_ENVIRONMENT is #defined, for Windows only, QUtil::get_env will always return false. This was added to support a user who needs to avoid calling GetEnvironmentVariable from the Windows API. QUtil::get_env is not used for any functionality in qpdf and exists only to support the test suite including test coverage support with QTC (part of qtest). * Add /FS to msvc builds to allow parallel builds to work with Visual C++ 2013. * Add missing #include <algorithm> in some files that use std::min and std::max. 2013-11-21 Jay Berkenbilt <firstname.lastname@example.org> * Change image comparison tests, which are disabled by default, to use tiff files with 8 bits per sample rather than 4. This works around a bug in tiffcmp but also increases time and disk space for image comparison tests. 2013-10-28 Jay Berkenbilt <email@example.com> * Fix MacOS compilation errors by adding a missing #include <string> in a header file.

Update to 5.0.1: 2013-10-18 Jay Berkenbilt <firstname.lastname@example.org> * 5.0.1: release * Warn when -accessibility=n is specified with a modern encryption format (R > 3). Also, accept this flag (and ignore with warning) with 256-bit encryption. qpdf has always ignored the accessibility setting with R > 3, but it previously did so silently. 2013-10-05 Jay Berkenbilt <email@example.com> * Replace operator in std::string and std::vector with "at" in order to get bounds checking. This reduces the chances that incorrect code will result in data exposure or buffer overruns. See README.hardening for additional notes. * Use cryptographically secure random number generation when available. See additional notes in README. * Replace some assert() calls with std::logic_error exceptions. Ideally there shouldn't be assert() calls outside of testing. This change may make a few more potential code errors in handling invalid data recoverable. * Security fix: In places where std::vector<T>(size_t) was used, either validate that the size parameter is sane or refactor code to avoid the need to pre-allocate the vector. This reduces the likelihood of allocating a lot of memory in response to invalid data in linearization hint streams. * Security fix: sanitize /W array in cross reference stream to avoid a potential integer overflow in a multiplication. It is unlikely that any exploits were possible from this bug as additional checks were also performed. * Security fix: avoid buffer overrun that could be caused by bogus data in linearization hint streams. The incorrect code could only be triggered when checking linearization data, which must be invoked explicitly. qpdf does not check linearization data when reading or writing linearized files, but the qpdf --check command does check linearization data. * Security fix: properly handle empty strings in QPDF_Name::normalizeName. The empty string is not a valid name and would never be parsed as a name, so there were no known conditions where this method could be called with an empty string. * Security fix: perform additional argument sanity checks when reading bit streams. * Security fix: in QUtil::toUTF8, change bounds checking to avoid having a pointer point temporarily outside the bounds of an array. Some compiler optimizations could have made the original code unsafe. 2013-07-10 Jay Berkenbilt <firstname.lastname@example.org> * 5.0.0: release * 4.2.0 turned out to be binary incompatible on some platforms even though there were no changes to the public API. Therefore the 4.2.0 release has been withdrawn, and is being replaced with a 5.0.0 release that acknowledges the ABI change and also removes some problematic methods from the public API. * Remove methods from public API that were only intended to be used by QPDFWriter and really didn't make sense to call from anywhere else as they required internal knowledge that only QPDFWriter had: - QPDF::getLinearizedParts - QPDF::generateHintStream - QPDF::getObjectStreamData - QPDF::getCompressibleObjGens - QPDF::getCompressibleObjects 2013-07-07 Jay Berkenbilt <email@example.com> * 4.2.0: release [withdrawn] * Ignore error case of a stream's decode parameters having invalid length when there are no stream filters. * qpdf: add --show-npages command-line option, which causes the number of pages in the input file to be printed on a line by itself. * qpdf: allow omission of range in --pages. If range is omitted such that an argument that is supposed to be a range is an invalid range and a valid file name, the range of 1-z is assumed. This makes it possible to merge a bunch of files with something like qpdf --empty out.pdf --pages *.pdf -- 2013-06-15 Jay Berkenbilt <firstname.lastname@example.org> * Handle some additional broken files with missing /ID in trailer for encrypted files and with space rather than newline after xref. 2013-06-14 Jay Berkenbilt <email@example.com> * Detect and correct /Outlines dictionary being a direct object when linearizing files. This is not allowed by the spec but has been seen in the wild. Prior to this change, such a file would cause an internal error in the linearization code, which assumed /Outlines was indirect. * Add /Length key to crypt filter dictionary for encrypted files. This key is optional, but some version of MacOS reportedly fail to open encrypted PDF files without this key. * Bug fix: properly handle object stream generation when the original file has some compressible objects with generation != 0. * Add QPDF::getCompressibleObjGens() and deprecate QPDF::getCompressibleObjects(), which had a flaw in its logic. * Add new QPDFObjectHandle::getObjGen() method and indiciate in comments that its use is favored over getObjectID() and getGeneration() for most cases. * Add new QPDFObjGen object to represent an object ID/generation pair. 2013-04-14 Jay Berkenbilt <firstname.lastname@example.org> * 4.1.0: release 2013-03-25 Jay Berkenbilt <email@example.com> * manual/qpdf-manual.xml: Document the casting policy that is followed in qpdf's implementation. 2013-03-11 Jay Berkenbilt <firstname.lastname@example.org> * When creating Windows binary distributions, make sure to only copy DLLs of the correct type. The ensures that the 32-bit distributions contain 32-bit DLLs and the 64-bit distributions contain 64-bit DLLs. 2013-03-07 Jay Berkenbilt <email@example.com> * Use ./install-sh (already present) instead of "install -c" to install executables to fix portability problems against different UNIX variants. 2013-03-03 Jay Berkenbilt <firstname.lastname@example.org> * Add protected terminateParsing method to QPDFObjectHandle::ParserCallbacks that implementor can call to terminate parsing of a content stream. 2013-02-28 Jay Berkenbilt <email@example.com> * Favor fopen_s and strerror_s on MSVC to avoid CRT security warnings. This is useful for people who may want to use qpdf in an application that is Windows 8 certified. * New method QUtil::safe_fopen to wrap calls to fopen. This is less cumbersome than calling QUtil::fopen_wrapper. * Remove all calls to sprintf * New method QUtil::int_to_string_base to convert to octal or hexademical (or decimal) strings without using sprintf 2013-02-26 Jay Berkenbilt <firstname.lastname@example.org> * Rewrite QUtil::int_to_string and QUtil::double_to_string to remove internal length limits but to remain backward compatible with the old versions for valid inputs. 2013-02-23 Jay Berkenbilt <email@example.com> * Bug fix: properly handle overridden compressed objects. When caching objects from an object stream, only cache objects that, based on the xref table, would actually be resolved into this stream. Prior to this fix, if an object stream A contained an object B that was overridden by an appended section of the file, qpdf would cache the old value of B if any non-overridden member of A was accessed before B. This commit fixes that bug. 2013-01-31 Jay Berkenbilt <firstname.lastname@example.org> * Do not remove libtool's .la file during the make install step. Note to packagers: if your distribution wants to you remove the .la file, you will have to do that yourself now. 2013-01-25 Jay Berkenbilt <email@example.com> * New method QUtil::hex_encode to encode binary data as a hexadecimal string * qpdf --check was exiting with status 0 in some rare cases even when errors were found. It now always exits with one of the document error codes (0 for success, 2 for errors, 3 or warnings). 2013-01-24 Jay Berkenbilt <firstname.lastname@example.org> * Make --enable-werror work for MSVC, and generally handle warning options better for that compiler. Warning flags for that compiler were previous hard-coded into the build with /WX enabled unconditionally. * Split warning flags into WFLAGS in autoconf.mk to make them easier to override. Before they were repeated in CFLAGS and CXXFLAGS and were commingled with other compiler flags. * qpdf --check now does syntactic checks all pages' content streams as well as checking overall document structure. Semantic errors are still not checked, and there are no plans to add semantic checks. 2013-01-22 Jay Berkenbilt <email@example.com> * Add QPDFObjectHandle::getTypeCode(). This method returns a unique integer (enumerated type) value corresponding to the object type of the QPDFObjectHandle. It can be used as an alternative to the QPDFObjectHandle::is* methods for type testing, particularly where there is a desire to use a switch statement or optimize for performance when testing object types. * Add QPDFObjectHandle::getTypeName(). This method returns a string literal describing the object type. It is useful for testing and debugging. 2013-01-20 Jay Berkenbilt <firstname.lastname@example.org> * Add QPDFObjectHandle::parseContentStream, which parses the objects in a content stream and calls handlers in a callback class. The example pdf-parse-content illustrates it use. * Add QPDF_Operator and QPDF_InlineImage types along with appropriate wrapper methods in QPDFObjectHandle. These new object types are to facilitate content stream parsing.

Import qpdf-4.0.1 as print/qpdf, packaged by dillo@. QPDF is a command-line program that does structural, content-preserving transformations on PDF files. It could have been called something like pdf-to-pdf. It also provides many useful capabilities to developers of PDF-producing software or for people who just want to look at the innards of a PDF file to learn more about how they work. QPDF is capable of creating linearized (also known as web-optimized) files and encrypted files. It is also capable of converting PDF files with object streams (also known as compressed objects) to files with no compressed objects or to generate object streams from files that don't have them (or even those that already do). QPDF also supports a special mode designed to allow you to edit the content of PDF files in a text editor. For more details, please see the documentation links below. QPDF includes support for merging and splitting PDFs through the ability to copy objects from one PDF file into another and to manipulate the list of pages in a PDF file. The QPDF library also makes it possible for you to create PDF files from scratch. In this mode, you are responsible for supplying all the contents of the file, while the QPDF library takes care off all the syntactical representation of the objects, creation of cross references tables and, if you use them, object streams, encryption, linearization, and other syntactic details. QPDF is not a PDF content creation library, a PDF viewer, or a program capable of converting PDF into other formats. In particular, QPDF knows nothing about the semantics of PDF content streams. If you are looking for something that can do that, you should look elsewhere. However, once you have a valid PDF file, QPDF can be used to transform that file in ways perhaps your original PDF creation can't handle. For example, programs generate simple PDF files but can't password-protect them, web-optimize them, or perform other transformations of that type.
