Raw Blame History

2017-09-12 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.org>
* Add support for writing PCLm files. Most of the work was done by
Sahil Arora <sahilarora.535@gmail.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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.org>
* Fix off-by-one error in parsing pages options. Fixes #129.
2017-07-29 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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.
2015-11-10 Jay Berkenbilt <ejb@ql.org>
* 6.0.0: release
* No changes from 5.2.0. The 5.2.0 release broke binary
compatibility and was withdrawn.
2015-10-31 Jay Berkenbilt <ejb@ql.org>
* 5.2.0: release
* libqpdf/QPDF.cc (read_xrefTable): Be tolerant of some malformed
xref tables that don't have the required trailing space after each
line.
2015-10-29 Jay Berkenbilt <ejb@ql.org>
* Implement QPDFWriter::setDeterministicID and --deterministic-id
commandline-flag to qpdf to request generation of a deterministic
/ID for non-encrypted files.
2015-05-24 Jay Berkenbilt <ejb@ql.org>
* 5.1.3: release
* Bug fix: fix-qdf was not handling object streams with more than
255 objects in them.
* Handle Microsoft crypt provider initialization properly for case
where no keys have been previously created, such as in a fresh
Windows installation.
* Include time.h in QUtil.hh for time_t
2015-02-21 Jay Berkenbilt <ejb@ql.org>
* Detect loops in Pages structure. Thanks to Gynvael Coldwind and
Mateusz Jurczyk of the Google Security Team for providing a sample
file with this problem.
* Prevent buffer overrun when converting a password to an
encryption key. Thanks to Gynvael Coldwind and Mateusz Jurczyk of
the Google Security Team for providing a sample file with this
problem.
* Ensure that arguments to "R" when parsing the file are direct
objects before trying to resolve them. This prevents specially
crafted files from causing qpdf to crash with a stack overflow.
Thanks to Gynvael Coldwind and Mateusz Jurczyk of the Google
Security Team for providing a sample file with this problem.
2014-12-01 Jay Berkenbilt <ejb@ql.org>
* Some broken PDF files lack the required /Type key for /Page and
/Pages nodes in the page dictionary. QPDF now uses other methods
to figure out what kind of node it is looking at so that it can
handle those files. Original reported at
https://bugs.launchpad.net/ubuntu/+source/qpdf/+bug/1397413
2014-11-14 Jay Berkenbilt <ejb@ql.org>
* Bug fix: QPDFObjectHandle::getPageContents() no longer throws an
exception when called on a page that has no /Contents key in its
dictionary. This is allowed by the spec, and some software
packages generate files like this for pages that are blank in the
original.
2014-06-07 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 5.1.1: release
2013-12-26 Jay Berkenbilt <ejb@ql.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 <ejb@ql.org>
* 5.1.0: release
2013-12-16 Jay Berkenbilt <ejb@ql.org>
* Document and make explicit that passing null to
QUtil::setRandomDataProvider() resets the random data provider.
* Provide QUtil::getRandomDataProvider().
2013-12-14 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* Fix MacOS compilation errors by adding a missing #include
<string> in a header file.
2013-10-18 Jay Berkenbilt <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.org>
* 4.1.0: release
2013-03-25 Jay Berkenbilt <ejb@ql.org>
* manual/qpdf-manual.xml: Document the casting policy that is
followed in qpdf's implementation.
2013-03-11 Jay Berkenbilt <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.org>
* Add protected terminateParsing method to
QPDFObjectHandle::ParserCallbacks that implementor can call to
terminate parsing of a content stream.
2013-02-28 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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 <ejb@ql.org>
* 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 <ejb@ql.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.
2013-01-17 Jay Berkenbilt <ejb@ql.org>
* 4.0.1: release
* Add clarifying comment in QPDF.hh for methods that return the
user password to state that it is no longer possible with newer
encryption formats to recover the user password knowing the owner
password.
* Fix detection of binary attachments in the test suite. This
resolves false test failures on some platforms. No changes to the
actual QPDF code were made.
2012-12-31 Jay Berkenbilt <ejb@ql.org>
* 4.0.0: release
* Add new methods qpdf_get_pdf_extension_level,
qpdf_set_r5_encryption_parameters,
qpdf_set_r6_encryption_parameters,
qpdf_set_minimum_pdf_version_and_extension, and
qpdf_force_pdf_version_and_extension to support new functionality
from the C API.
2012-12-30 Jay Berkenbilt <ejb@ql.org>
* Fix long-standing bug that could theoretically have resulted in
possible misinterpretation of decode parameters in streams. As
far as I can tell, it is extremely unlikely that files with the
characteristics that would have triggered the bug actually exist
in cases that qpdf versions prior to 4.0.0 could have read.
Unencrypted files with encrypted attachments would have triggered
this bug, but qpdf versions prior to 4.0.0 already refused to open
such files.
* Fix long-standing bug in which a stream that used a crypt
filter and was otherwise not filterable by qpdf would be decrypted
properly but would retain the crypt filter indication in the
file. There are no known ways to create files like this, so it is
unlikely that anyone ever hit this bug.
2012-12-29 Jay Berkenbilt <ejb@ql.org>
* Add read/write support for both the deprecated Acrobat IX
encryption format and the Acrobat X/PDF 2.0 encryption format
using 256-bit AES keys. Using the Acrobat IX format (R=5) forces
the version of the file to 1.7 with extension level 3. Using the
PDF 2.0 format (R=6) forces it to 1.7 extension level 8.
* Add new method QPDF::getEncryptionKey to return the actual
encryption key used for encryption of data in the file. The key
is returned as a std::string.
* Non-compatible API change: change signature of
QPDF::compute_data_key to take the R and V values from the
encryption dictionary. There is no reason for any application
code to call this method since handling of encryption is done
automatically by the qpdf libary. It is used internally by
QPDFWriter.
* Support reading and decryption of files whose main text is not
encrypted but whose attachments are. More generally, support the
case of files and streams encrypted differently with some
limitations, described in the documentation. This was not
previously supported due to lack of test files, but I created test
files using a trial version of Acrobat XI to fully implement this
case.
* Incorporate sha2 code from sphlib 3.0. See README for
licensing. Create private pipeline class for computing hashes
with sha256, sha384, and sha512.
* Allow specification of initialization vector when using AES
filtering. This is required to compute the hash used in /R=6 (PDF
2.0) encryption.
2012-12-28 Jay Berkenbilt <ejb@ql.org>
* Add random number generation functions to QUtil.
* Fix old bug that could cause an infinite loop if user password
recovery methods were called and a password contained the "("
character (which happens to be the first byte of padding used by
older PDF encryption formats). This bug was noticed while reading
code and would not happen under ordinary usage patterns even if
the password contained that character.
2012-12-27 Jay Berkenbilt <ejb@ql.org>
* Add awareness of extension level to PDF Version methods for both
reading and writing. This includes adding method
QPDF::getExtensionLevel and new versions of
QPDFWriter::setMinimumPDFVersion and QPDFWriter::forcePDFVersion
that support extension levels. The qpdf command-line tool
interprets version numbers of the form x.y.z as version x.y at
extension level z.
* Update AES classes to support use of 256-bit keys.
* Non-compatible API change: Removed public method
QPDF::flattenScalarReferences. Instead, just flatten the scalar
references we actually need to flatten. Flattening scalar
references was a wrong decision years ago and has occasionally
caused other problems, among which were that it caused qpdf to
visit otherwise unreferenced and possibly erroneous objects in the
file when it didn't have to. There's no reason that any
non-internal code would have had to call this.
* Non-compatible API change: Removed public method
QPDF::decodeStreams which was previously used by qpdf --check but
is no longer used. The decodeStreams method could generate false
positives since it would attempt to access all objects in the file
including those that were not referenced. There's no reason that
any non-internal code would have had to call this.
* Non-compatible API change: Removed public method
QPDF::trimTrailerForWrite, which was only intended for use by
QPDFWriter and which is no longer used.
2012-12-26 Jay Berkenbilt <ejb@ql.org>
* Add new fields to QPDF::EncryptionData to support newer
encryption formats (V=5, R=5 and R=6)
* Non-compatible API change: Change public nested class
QPDF::EncryptionData to make all member fields private and to add
method calls. This is a non-compatible API change, but changing
EncryptionData is necessary to support newer encryption formats,
and making this change will prevent the need from making a
non-compatible change in the future if new fields are added. A
public nested class should never have had public members to begin
with.

* Allow PDF header to appear anywhere in the first 1024 bytes of
the file as recommended in the implementation notes of the Adobe
version of the PDF spec.
2012-11-20 Jay Berkenbilt <ejb@ql.org>
* Add zlib and libpcre to Requires.private in the pkg-config file
to support static linking. Thanks Tobias Hoffmann for pointing
out the omission.
* Ignore (with warning) non-freed objects in the xref table whose
offset is 0. Some PDF producers (incorrectly) do this. See
https://bugs.linuxfoundation.org/show_bug.cgi?id=1081.
2012-09-23 Jay Berkenbilt <ejb@ql.org>
* Add public methods QPDF::processInputSource and
QPDFWriter::setOutputPipeline to allow users to read from custom
input sources and to write to custom pipelines. This allows the
maximum flexibility in sources for reading and writing PDF files.
2012-09-06 Jay Berkenbilt <ejb@ql.org>
* 3.0.2: release
* Add new method QPDFWriter::setExtraHeaderText to add extra text,
such as application-specific comments, to near the beginning of a
PDF file. For linearized files, this appears after the
linearization parameter dictionary. For non-linearized files, it
appears right after the PDF header and non-ASCII comment.
* Make it possible to write the same QPDF object with two
different QPDFWriter objects that have both called
setLinearization(true) by making private method
QPDF::calculateLinearizationData() properly initialize its state.
* Bug fix: Writing after calling QPDFWriter::setOutputMemory()
would cause a segmentation fault because of an internal field not
being initialized, rendering that method useless. This has been
corrected.
2012-08-11 Jay Berkenbilt <ejb@ql.org>
* 3.0.1: release
* Bug fix: let EOF terminate a literal token as well as
whitespace or comments.
2012-07-31 Jay Berkenbilt <ejb@ql.org>
* 3.0.0: release
2012-07-29 Jay Berkenbilt <ejb@ql.org>
* 3.0.rc1: release
2012-07-25 Jay Berkenbilt <ejb@ql.org>
* From Tobias: add QPDFObjectHandle::replaceStreamData that takes
a std::string analogous to the QPDFObjectHandle::newStream that
takes a string that was added earlier.
2012-07-21 Jay Berkenbilt <ejb@ql.org>
* Change configure to have image comparison tests disabled by
default. Update README and README.maintainer with information
about running them.
* Add --pages command-line option to qpdf to enable page-based
merging and splitting.
* Add new method QPDFObjectHandle::replaceDict to replace a
stream's dictionary. Use with caution; see comments in
QPDFObjectHandle.hh.
* Add new method QPDFObjectHandle::parse for creation of
QPDFObjectHandle objects from string representations of the
objects. Thanks to Tobias Hoffmann for the idea.
2012-07-15 Jay Berkenbilt <ejb@ql.org>
* add new QPDF::isEncrypted method that returns some additional
information beyond other versions.
* libqpdf/QPDFWriter.cc: fix copyEncryptionParameters to fix the
minimum PDF version based on other file's encryption needs. This
is a fix to code added on 2012-07-14 and did not impact previously
released code.
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): Bug fix: qpdf
was not preserving whether or not AES encryption was being used
when copying encryption parameters. The file would still have
been properly encrypted, but a file that started off encrypted
with AES could have become encrypted with RC4.
2012-07-14 Jay Berkenbilt <ejb@ql.org>
* QPDFWriter: add public copyEncryptionParameters to allow copying
encryption parameters from another file.
* QPDFWriter: detect if the user has inserted an indirect object
from another QPDF object and throw an exception directing the user
to copyForeignObject.
2012-07-11 Jay Berkenbilt <ejb@ql.org>
* Added new APIs to copy objects from one QPDF to another. This
includes letting QPDF::addPage() (and QPDF::addPageAt()) accept a
page object from another QPDF and adding
QPDF::copyForeignObject(). See QPDF.hh for details.
* Add method QPDFObjectHandle::getOwningQPDF() to return the QPDF
object associated with an indirect QPDFObjectHandle.
* Add convenience methods to QPDFObjectHandle: assertIndirect(),
isPageObject(), isPagesObject()
* Cache when QPDF::pushInheritedAttributesToPage() has been called
to avoid traversing the pages trees multiple times. This state is
cleared by QPDF::updateAllPagesCache() and ignored by
QPDF::flattenPagesTree().
2012-07-08 Jay Berkenbilt <ejb@ql.org>
* Add QPDFObjectHandle::newReserved to create a reserved object
and QPDF::replaceReserved to replace it with a real object.
QPDFObjectHandle::newReserved reserves an object ID in a QPDF
object and ensures that any references to it remain unresolved.
When QPDF::replaceReserved is later called, previous references to
the reserved object will properly resolve to the replaced object.
2012-07-07 Jay Berkenbilt <ejb@ql.org>
* NOTE: BREAKING API CHANGE. Remove previously required length
parameter from the version QPDFObjectHandle::replaceStreamData
that uses a stream data provider. Prior to qpdf 3.0.0, you had to
compute the stream length in advance so that qpdf could internally
verify that the stream data had the same length every time the
provider was invoked. Now this requirement is enforced a
different way, and the length parameter is no longer required.
Note that I take API-breaking changes very seriously and only did
it in this case since the lack of need to know length in advance
could significantly simplify people's code. If you were
previously going to a lot of trouble to compute the length of the
new stream data in advance, you now no longer have to do that.
You can just drop the length parameter and remove any code that
was previously computing the length. Thanks to Tobias Hoffmann
for pointing out how annoying the original interface was.
2012-07-05 Jay Berkenbilt <ejb@ql.org>
* Add QPDFWriter methods to write to an already open stdio FILE*.
Implementation and idea area based on contributions from Tobias
Hoffmann.
2012-07-04 Jay Berkenbilt <ejb@ql.org>
* Accept changes from Tobias Hoffmann: add public method
QPDF::pushInheritedAttributesToPage including warnings for
non-inherited keys that may be discarded from /Pages by
non-conformant PDF files when the /Pages tree is flattened.
2012-06-27 Jay Berkenbilt <ejb@ql.org>
* Add Pl_Concatenate pipeline for stream concatenation also
implemented by Tobias Hoffmann. Also added test code
(libtests/concatenate.cc).
* Add new methods implemented by Tobias Hoffmann:
QPDFObjectHandle::newReal(double) and
QPDFObjectHandle::newStream(QPDF*, std::string const&).
2012-06-26 Jay Berkenbilt <ejb@ql.org>
* Minor changes so that support for PDF files larger than 4GB
works well with 32-bit and 64-bit Linux and also with 32-bit and
64-bit Windows with both MSVC and mingw.
* Rework internal methods for doing recovery of the cross
reference tables for much greater efficiency both in terms of time
and memory usage.
2012-06-24 Jay Berkenbilt <ejb@ql.org>
* Support PDF files larger than 4 GB. This involved many changes
to the ABI to increase the size of integer types used in various
places as well as increasing the amount of padding used when
creating linearized files. Automated tests for large files are
disabled by default. Run ./configure --help for information on
enabling them. Running the tests requires 11 GB of free disk
space and takes several minutes.
2012-06-22 Jay Berkenbilt <ejb@ql.org>
* examples/pdf-create.cc: Provide an example of creating a PDF
from scratch. This simple PDF has a single page with some text
and an image.
* Add empty QPDFObjectHandle factories for array and dictionary.
With PDF-from-scratch capability, it is useful to be able to
create empty arrays and dictionaries and add keys to them.
Updated pdf_from_scratch.cc to use these interfaces.
2012-06-21 Jay Berkenbilt <ejb@ql.org>
* Add QPDF::emptyPDF() to create an empty QPDF object suitable for
adding pages and other objects to. pdf_from_scratch.cc is test
code that exercises it.
* make/libtool.mk: Place user-specified CPPFLAGS and LDFLAGS later
in the compilation so that if a user installs things in a
non-standard place that they have to tell the build about, earlier
versions of qpdf installed there won't break the build. Thanks to
Macports for reporting this. (Fixes bug 3468860.)
* Instead of using off_t in the public APIs, use qpdf_offset_t
instead. This is defined as long long in qpdf/Types.h. If your
system doesn't support long long, you can redefine it.
* Add pkg-config files
* QPDFObjectHandle: add shallowCopy() method
* QPDF: add new APIs for adding and removing pages. This includes
addPage(), addPageAt(), and removePage(). Also a method
updateAllPagesCache() is now available to force update of the
internal pages cache if you should modify the pages structure
manually.
* QPDF: new processFile method that takes an open FILE*
instead of a filename.
2012-06-20 Jay Berkenbilt <ejb@ql.org>
* Add new array mutation routines to QPDFObjectHandle.
Implemented by Tobias Hoffmann.
* Rework APIs that use size_t, off_t, and primative integer types
so that size_t is used for sizes of memory and off_t is used for
file offsets. Also set _FILE_OFFSET_BITS so that large files can
be supported on 32-bit UNIX/Linux platforms. The code assumes in
places that sizeof(off_t) >= sizeof(size_t). This resulted in
non-compatible ABI changes and hopefully clears the way for QPDF
to work with files that are larger than 4 GiB in size.
* Add support for versioned symbols on ELF platforms.
* Various fixes for gcc 4.7
2011-04-06 Jay Berkenbilt <ejb@ql.org>
* Fix PCRE to stop using deprecated (and now dropped) interfaces.
2011-12-28 Jay Berkenbilt <ejb@ql.org>
* 2.3.1: release
* include <stdint.h> if available to support MSVC 2010
* Since PCRE is not necessarily thread safe, don't declare any
PCRE objects to be static.
* Disregard stderr output from ghostscript when using it to
compare images in the test suite; see comments in qpdf.test for
details.
* Fixed a few documentation errors.
2011-08-11 Jay Berkenbilt <ejb@ql.org>
* 2.3.0: release
* include/qpdf/qpdf-c.h ("C"): add new methods
qpdf_init_write_memory, qpdf_get_buffer_length, and
qpdf_get_buffer to support writing to memory from the C API.
* include/qpdf/qpdf-c.h ("C"): add new methods qpdf_get_info_key
and qpdf_set_info_key for manipulating text fields of the /Info
dictionary.
2011-08-10 Jay Berkenbilt <ejb@ql.org>
* libqpdf/QPDFWriter.cc (copyEncryptionParameters): preserve
whether metadata is encryption. This fixes part of bug 3173659:
the password becomes invalid if qpdf copies an encrypted file with
cleartext-metadata.
* include/qpdf/QPDFWriter.hh: add a new constructor that takes
only a QPDF reference and leaves specification of output for
later. Add methods setOutputFilename() to set the output to a
filename or stdout, and setOutputMemory() to indicate that output
should go to a memory buffer. Add method getBuffer() to retrieve
the buffer used if output was saved to a memory buffer.
* include/qpdf/QPDF.hh: add methods replaceObject() and
swapObjects() to allow replacement of an object and swapping of
two objects by object ID.
* include/qpdf/QPDFObjectHandle.hh: add new methods getDictAsMap()
and getArrayAsVector() for returning the elements of a dictionary
or an array as a map or vector.
2011-06-25 Jay Berkenbilt <ejb@ql.org>
* 2.2.4: release
2011-06-23 Jay Berkenbilt <ejb@ql.org>
* make/libtool.mk (install): Do not strip executables and shared
libraries during installation. Leave that up to the packager.
* configure.ac: disable -Werror by default.
2011-05-07 Jay Berkenbilt <ejb@ql.org>
* libqpdf/QPDF_linearization.cc (isLinearized): remove unused
offset variable, found by a gcc 4.6 warning.
2011-04-30 Jay Berkenbilt <ejb@ql.org>
* 2.2.3: release
* libqpdf/QPDF.cc (readObjectInternal): Accept the case of the
stream keyword being followed by carriage return by itself. While
this is not permitted by the specification, there are PDF files
that do this, and other readers can read them.
* libqpdf/Pl_QPDFTokenizer.cc (processChar): When an inline image
is detected, suspend normalization only up to the end of the
inline image rather than for the remainder of the content stream.
(Fixes qpdf-Bugs 3152169.)
2011-01-31 Jay Berkenbilt <ejb@ql.org>
* libqpdf/QPDF.cc (readObjectAtOffset): use -1 rather than 0 when
reading an object at a given to indicate that no object number is
expected. This allows xref recovery to proceed even if a file
uses the invalid object number 0 as a regular object.
* libqpdf/QPDF_linearization.cc (isLinearized): use -1 rather than
0 as a sentintel for not having found the first object in the
file. Since -1 can never match the regular expression, this
prevents an infinite loop when checking a file that starts with
(erroneous) 0 0 obj. (Fixes qpdf-Bugs-3159950.)
2010-10-04 Jay Berkenbilt <ejb@ql.org>
* 2.2.2: release
* include/qpdf/qpdf-c.h: Add qpdf_read_memory to C API to call
QPDF::processMemoryFile.
2010-10-01 Jay Berkenbilt <ejb@ql.org>
* 2.2.1: release
* include/qpdf/QPDF.hh: Add setOutputStreams method to allow
redirection of library-generated output/error to alternative
streams.
* include/qpdf/QPDF.hh: Add processMemoryFile method for
processing a PDF file from a memory buffer instead of a file.
2010-09-24 Jay Berkenbilt <ejb@ql.org>
* libqpdf/QPDF.cc: change private "file" method to be a
PointerHolder<InputSource> to prepare qpdf for being able to work
with PDF files loaded into memory in addition to working with
files on disk.
* include/qpdf/PointerHolder.hh: add operator* and operator->
methods so that PointerHolder objects can be used like pointers.
This is consistent with the smart pointer objects in the next
revision of C++.
2010-09-05 Jay Berkenbilt <ejb@ql.org>
* libqpdf/QPDF.cc (readObjectInternal): Recognize empty objects
and treat them as null.
* libqpdf/QPDF_Stream.cc (filterable): Handle inline image filter
abbreviations as stream filter abbreviations. Although this is
not technically allowed by the PDF specification, table H.1 in the
pre-ISO spec indicates that Adobe's readers accept them. Thanks
to Jian Ma <stronghorse@tom.com> for bringing this to my
attention.
2010-08-14 Jay Berkenbilt <ejb@ql.org>
* 2.2.0: release
* Rename README.windows to README-windows.txt and convert its line
endings to Windows-style line endings. Also mention Jian Ma's VC6
port in the manual and README-windows.txt.
2010-08-09 Jay Berkenbilt <ejb@ql.org>
* Add QPDFObjectHandle::getRawStreamData to return raw
(unfiltered) stream data.
2010-08-08 Jay Berkenbilt <ejb@ql.org>
* 2.2.rc1: release
2010-08-05 Jay Berkenbilt <ejb@ql.org>
* Add QPDFObjectHandle::addPageContents, a convenience routine for
appending or prepending new streams to a page's content streams.
The "pdf-double-page-size" example illustrates its use.
* Add new methods to QPDFObjectHandle: replaceStreamData and
newStream. These methods allow users of the qpdf library to add
new streams and to replace data of existing streams. The
"pdf-double-page-size" and "pdf-invert-images" examples illustrate
their use.
2010-06-06 Jay Berkenbilt <ejb@ql.org>
* Fix memory leak for QPDF objects whose underlying PDF objects
contain circular references. Thanks to Jian Ma
<stronghorse@tom.com> for calling my attention to the memory leak.
2010-04-25 Jay Berkenbilt <ejb@ql.org>
* 2.1.5: release
* libqpdf/QPDF_encryption.cc (compute_encryption_key): remove
restrictions on length of file identifier string. (Fixes
qpdf-Bugs-2991412.)
2010-04-18 Jay Berkenbilt <ejb@ql.org>
* 2.1.4: release
* libqpdf/QPDFWriter.cc (writeLinearized): the padding calculation
fix in 2.1.2 was applied in only one place but it was needed in
two places since there are actually two cross reference streams in
a linearized file. The new padding calculation is now used for
both streams. Hopefully this should put an end to linearization
padding problems. (Fixes qpdf-Bugs-2979219.)
2010-04-10 Jay Berkenbilt <ejb@ql.org>
* qpdf/qpdf.cc (main): Since qpdf --check only checks syntax and
stream encoding without doing any semantic checks, make the output
clearer when no errors around found. This is inspired by
qpdf-Bugs-2983225.
2010-03-27 Jay Berkenbilt <ejb@ql.org>
* 2.1.3: release
* libqpdf/QPDF_optimization.cc (flattenScalarReferences): Flatten
scalar references for unreferenced objects as well as those seen
during traversal of the file. This matters when preserving object
streams that contain unreferenced objects with indirect scalars.
(Fixes qpdf-Bugs-2974522.) Updated TODO with a description of a
possibly better fix involving removal of flattenScalarReferences.
* libqpdf/Pl_AES_PDF.cc (finish): Don't complain if an AES input
buffer is not a multiple of 16 bytes. Instead, just pad with
nulls and hope for the best. PDF files have been encountered "in
the wild" that contain AES buffers that aren't a multiple of 16
bytes.
2010-01-24 Jay Berkenbilt <ejb@ql.org>
* 2.1.2: release
* libqpdf/QPDFWriter.cc: fix logic error in padding calculation.
When writing linearized files with cross reference streams, the
padding calculation failed to take differences in sizes of
compressed data between pass 1 and pass 2 into consideration.
2009-12-14 Jay Berkenbilt <ejb@ql.org>
* 2.1.1: release
* qpdf/qtest/qpdf.test: improve test for acroread to make sure it
actually works and is not just present in the path.
2009-12-13 Jay Berkenbilt <ejb@ql.org>
* libqpdf/qpdf/Pl_AES_PDF.hh: include <stdint.h>, if available, so
we have valid definitions of uint32_t.
2009-10-30 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.org>
* 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 <ejb@ql.org>
* 2.1.rc1: release
* Provide interfaces for getting qpdf's own version number
2009-10-19 Jay Berkenbilt <ejb@ql.org>
* 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 <ejb@ql.org>
* 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 <ejb@ql.org>
* 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 <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
