qpdf/ChangeLog

2009-10-19  Jay Berkenbilt  <jberkenb@argonst.com>

	* 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.

	* 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.

2009-10-04  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 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  This function has been replaced
	by QPDF::getPaddedUserPassword.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  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 2.0.5: release

2009-03-09  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 2.0.4: release

2009-02-20  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 2.0.3: release

2008-12-11  Jay Berkenbilt  <ejb@ql.org>

	* qpdf/qpdf.cc (main): Accept -help and -version as well as --help
	and --version

2008-11-23  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 2.0.2: release

	* updated embedded qtest to version 1.2 (includes previous
	changes)

2008-06-07  Jay Berkenbilt  <ejb@ql.org>

	* qpdf/qtest/qpdf/diff-encrypted: change == to = so that the test
	suite passes when /bin/sh is not bash

2008-05-07  Jay Berkenbilt  <ejb@ql.org>

	* qtest/bin/qtest-driver (run_test): increase timeout for qtest to
	be more tolerant of slow machines

2008-05-06  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* libqpdf/qpdf/MD5.hh: fix header to be 64-bit clean

	* configure.ac: add tests for sized integer types

2008-05-04  Jay Berkenbilt  <ejb@ql.org>

	* 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  <ejb@ql.org>

	* 2.0: initial public release
