2009-10-30 Jay Berkenbilt * 2.1: release * libqpdf/QPDF.cc: be more forgiving of extraneous whitespace in the xref table and while recovering from error conditions. 2009-10-26 Jay Berkenbilt * Work around failure of PCRE test case; this test case exercises an aspect of PCRE that qpdf does not use, and the test fails with the version of PCRE on Red Hat Enterprise Linux 5, so we ignore failure on this particular test case. * Fix RPM .spec file to include "C" examples 2009-10-24 Jay Berkenbilt * 2.1.rc1: release * Provide interfaces for getting qpdf's own version number 2009-10-19 Jay Berkenbilt * include/qpdf/QPDF.hh (QPDF): getWarnings now returns a list of QPDFExc rather than a list of strings. This way, warnings may be inspected in more detail. * Include information about the last object read in most error messages. Most of the time, this will provide a good hint as to which object contains the error, but it's possible that the last object read may not necessarily be the one that has the error if the erroneous object was previously read and cached. 2009-10-18 Jay Berkenbilt * If forcing version, disable object stream creation and/or encryption if previous specifications are incompatible with new version. It is still possible that PDF content, compression schemes, etc., may be incompatible with the new version, but at least this way, older viewers will at least have a chance. * libqpdf/QPDFWriter.cc (unparseObject): avoid compressing Metadata streams if possible. 2009-10-13 Jay Berkenbilt * Upgrade embedded qtest to version 1.4, which allows the test suite to be run in Windows with MSYS and ActiveState Perl rather than requiring Cygwin perl. 2009-10-04 Jay Berkenbilt * Implement support AES encrypt and crypt filters. Implementation is not fully tested due to lack of test data but has been tested for several cases. 2009-10-04 Jay Berkenbilt * Add methods to QPDFWriter and corresponding command line arguments to qpdf to set the minimum output PDF version and also to force the version to a particular value. * libqpdf/QPDF.cc (processXRefStream): warn and ignore extra xref stream entries when stream is larger than reported size. This used to be a fatal error. (Fixes qpdf-Bugs-2872265.) 2009-09-27 Jay Berkenbilt * Add several methods to query permissions controlled by the encryption dictionary. Note that qpdf does not enforce these permissions even though it allows the user to query them. * The function QPDF::getUserPassword returned the user password with the required padding as specified by the PDF specification. This is seldom useful to users. This function has been replaced by QPDF::getPaddedUserPassword. Call the new QPDF::getTrimmedUserPassword to retreive the user password in a human-readable format. * qpdf/qpdf.cc (main): qpdf --check now prints the PDF version number in addition to its other output. 2009-09-26 Jay Berkenbilt * Removed all references to QEXC; now using std::runtime_error and std::logic_error and their subclasses for all exceptions. 2009-05-03 Jay Berkenbilt * 2.0.6: release * libqpdf/QPDF_Stream.cc (filterable): ignore /DecodeParms if it's not a type we recognize. (Fixes qpdf-Bugs-2779746.) 2009-03-10 Jay Berkenbilt * 2.0.5: release 2009-03-09 Jay Berkenbilt * libqpdf/Pl_LZWDecoder.cc: adjust LZWDecoder full table detection, now having been able to adequately test boundary conditions both and with and without early code change. Also compared implementation with other LZW decoders. 2009-03-08 Jay Berkenbilt * qpdf/fix-qdf (write_ostream): Adjust offsets while writing object streams to account for changes in the length of the dictionary and offset tables. * qpdf/qpdf.cc (main): In check mode, in addition to checking structure of file, attempt to decode all stream data. * libqpdf/QPDFWriter.cc (QPDFWriter::writeObject): In QDF mode, write a comment to the QDF file before each object that indicates the object ID of the corresponding object from the original file. Add --no-original-object-ids flag to qpdf and setSuppressOriginalObjectIDs() method to QPDFWriter to turn this behavior off. * libqpdf/QPDF.cc (QPDF::pipeStreamData): Issue a warning instead of failing if there is a problem found while decoding stream. * qpdf/qpdf.cc: Exit with a status of 3 if warnings were found regardless of what mode we're in. 2009-02-21 Jay Berkenbilt * 2.0.4: release 2009-02-20 Jay Berkenbilt * Fix many typos in comments and strings. * qpdf/qpdf.cc: in --check mode, if there are warnings but no errors, exit with a status of 3. * libqpdf/QPDF.cc (QPDF::insertXrefEntry): when recovering the cross-reference table, have objects we encounter later in the file supersede those we found earlier. This improves the chances of being able to recover appended files with damaged cross-reference tables. 2009-02-19 Jay Berkenbilt * libqpdf/Pl_LZWDecoder.cc: correct logic error for previously untested case of running the LZW decoder without the "early code change" flag. Thanks to a bug report from "Atom Smasher", I finally was able to obtain an input stream compressed in this way. 2009-02-15 Jay Berkenbilt * 2.0.3: release 2008-12-11 Jay Berkenbilt * qpdf/qpdf.cc (main): Accept -help and -version as well as --help and --version 2008-11-23 Jay Berkenbilt * Include stdio.h in a few files for proper compilation with (yet to be released) gcc 4.4 * updated embedded qtest to version 1.3 * libqpdf/QPDF_String.cc (QPDF_String::getUTF8Val): handle UTF-16BE properly rather than just treating the string as a string of 16-bit characters. 2008-06-30 Jay Berkenbilt * 2.0.2: release * updated embedded qtest to version 1.2 (includes previous changes) 2008-06-07 Jay Berkenbilt * qpdf/qtest/qpdf/diff-encrypted: change == to = so that the test suite passes when /bin/sh is not bash 2008-05-07 Jay Berkenbilt * qtest/bin/qtest-driver (run_test): increase timeout for qtest to be more tolerant of slow machines 2008-05-06 Jay Berkenbilt * 2.0.1: release * make/rules.mk: fix logic with .dep generation for .lo files so that dependencies work properly with libtool 2008-05-05 Jay Berkenbilt * libqpdf/qpdf/MD5.hh: fix header to be 64-bit clean * configure.ac: add tests for sized integer types 2008-05-04 Jay Berkenbilt * libqpdf/QPDF_encryption.cc: do not assume size_t is unsigned int * qpdf/qtest/qpdf.test: removed locale-specific tests. These were really to check bugs in perl 5.8.0 and are obsolete now. They also make the test suite fail in some environments that don't have all the locales fully configured. * various: updated several files for gcc 4.3 by adding missing includes (string.h, stdlib.h) 2008-04-26 Jay Berkenbilt * 2.0: initial public release
