Don't include windows.h and wsockcompat.h from config.h but only when
needed.
Don't define _WINSOCKAPI_ manually. This was apparently done to stop
windows.h from including winsock.h which is a problem if winsock2.h
wasn't included first. But on MinGW, this causes compiler warnings.
Define WIN32_LEAN_AND_MEAN instead which has the same effect.
Always use the compiler-defined _WIN32 macro instead of WIN32.

Unfortunately this change has introduced a problem which results in
occasional hangs on Windows when running multi-threaded on a multi-core
host.
When locking the xmlRMutex the count field is increment inside the
critical section but when unlocking the count field is decremented
outside the critical section. The increment/decrement is not atomic so
this can result in the count field being updated incorrectly.
The solution is to change xmlRMutexUnlock to decrement the count field
before leaving the critical section rather than after.
Fixes bug #704908
The declarations of pthread functions, used to generate weak references
to them, fail to suppress macros. Thus, if any pthread function has
been provided as a macro, compiling threads.c will fail.
This breaks on musl libc, which defines pthread_equal as a macro (in
addition to providing the function, as required).
Prevent the declarations for e.g. musl libc by refining the condition.
The idea for this solution was borrowed from the alpine linux guys, see
http://git.alpinelinux.org/cgit/aports/tree/main/libxml2/libxml2-pthread.patch

Two threads entering xmlInitializeDict concurently could lead
to a lockup due to multiple initializations of the lock used.
To avoid this problem move this to a new private function
called from xmlOnceInit() and deprecate the old initalizer.
Since threaded programs must call xmlInitParser() and this
will lead to dereference of private data and the call to
xmlOnceInit() guaranteed to be unique this should be safe now.
cannot compile libxml2-2.9.0 using studio 12.1 compiler on solaris 10
I.M.O. structure initializer (as PTHREAD_ONCE_INIT) cannot be used in
a structure assignment anyway
While xmlCleanupParser() should not be used unless complete control
is insured over the programe making sure libxml2 is not in use anywhere
It should still be usable, and allow a sequence of
xmlInitParser();
xmlCleanupParser();
calls if needed, the problem is that the thread key wasn't reallocated
on subsequent xmlinitParser() calls leading to corruption of pthread
keys used by the program.
* threads.c: make sure xmlCleanupParser() reset the pthread_once()
global variable driving thread key allocation.
Makefile.am:
* Don't use @VAR@, use $(VAR). Autoconf's AC_SUBST provides us the Make
variable, it allows overriding the value at the command line, and
(notably) it avoids a Make parse error in the libxml2_la_LDFLAGS
assignment when @MODULE_PLATFORM_LIBS@ is empty
* Changed how the THREADS_W32 mechanism switches the build between
testThreads.c and testThreadsWin32.c as appropriate; using AM_CONDITIONAL
allows this to work cleanly and plays well with dependencies
* testapi.c should be specified as BUILT_SOURCES
* Create symlinks to the test/ and result/ subdirs so that the runtests
target is usable in out-of-source-tree builds
* Don't do MAKEFLAGS+=--silent as this is not portable to non-GNU Makes
* Fixed incorrect find(1) syntax in the "cleanup" rule, and doing "rm -f"
instead of just "rm" is good form
* (DIST)CLEANFILES needed a bit more coverage to allow "make distcheck" to
pass
configure.in:
* Need AC_PROG_LN_S to create test/ and result/ symlinks in Makefile.am
* AC_LIBTOOL_WIN32_DLL and AM_PROG_LIBTOOL are obsolete; these have been
superceded by LT_INIT
* Don't rebuild docs by default, as this requires GNU Make (as
implemented)
* Check for uint32_t as some platforms don't provide it
* Check for some more functions, and undefine HAVE_MMAP if we don't also
HAVE_MUNMAP (one system I tested on actually needed this)
* Changed THREADS_W32 from a filename insert into an Automake conditional
* The "Copyright" file will not be in the current directory if builddir !=
srcdir
doc/Makefile.am:
* EXTRA_DIST cannot use wildcards when they refer to generated files; this
breaks dependencies. What I did was define EXTRA_DIST_wc, which uses GNU
Make $(wildcard) directives to build up a list of files, and EXTRA_DIST,
as a literal expansion of EXTRA_DIST_wc. I also added a new rule,
"check-extra-dist", to simplify checking that the two variables are
equivalent. (Note that this works only when builddir == srcdir)
(I can implement this differently if desired; this is just one way of
doing it)
* Don't define an "all" target; this steps on Automake's toes
* Fixed up the "libxml2-api.xml ..." rule by using $(wildcard) for
dependencies (as Make doesn't process the wildcards otherwise) and
qualifying appropriate files with $(srcdir)
(Note that $(srcdir) is not needed in the dependencies, thanks to VPATH,
which we can count on as this is GNU-Make-only code anyway)
doc/devhelp/Makefile.am:
* Qualified appropriate files with $(srcdir)
* Added an "uninstall-local" rule so that "make distcheck" passes
doc/examples/Makefile.am:
* Rather than use a wildcard that doesn't work, use a substitution that
most Make programs can handle
doc/examples/index.py:
* Do the same here
include/libxml/nanoftp.h:
* Some platforms (e.g. MSVC 6) already #define INVALID_SOCKET:
user@host:/cygdrive/c/Program Files/Microsoft Visual Studio/VC98/\
Include$ grep -R INVALID_SOCKET .
./WINSOCK.H:#define INVALID_SOCKET (SOCKET)(~0)
./WINSOCK2.H:#define INVALID_SOCKET (SOCKET)(~0)
include/libxml/xmlversion.h.in:
* Support ancient GCCs (I was actually able to build the library with 2.5
but for this bit)
python/Makefile.am:
* Expanded CLEANFILES to allow "make distcheck" to pass
python/tests/Makefile.am:
* Define CLEANFILES instead of a "clean" rule, and added tmp.xml to allow
"make distcheck" to pass
testRelax.c:
* Use HAVE_MMAP instead of the less explicit HAVE_SYS_MMAN_H (as some
systems have the header but not the function)
testSchemas.c:
* Use HAVE_MMAP instead of the less explicit HAVE_SYS_MMAN_H
testapi.c:
* Don't use putenv() if it's not available
threads.c:
* This fixes the following build error on Solaris 8:
libtool: compile: cc -DHAVE_CONFIG_H -I. -I./include -I./include \
-D_REENTRANT -D__EXTENSIONS__ -D_REENTRANT -Dsparc -Xa -mt -v \

"threads.c", line 442: controlling expressions must have scalar type
"threads.c", line 512: controlling expressions must have scalar type
cc: acomp failed for threads.c
*** Error code 1
trio.c:
* Define isascii() if the system doesn't provide it
trio.h:
* The trio library's HAVE_CONFIG_H header is not the same as LibXML2's
HAVE_CONFIG_H header; this change is needed to avoid a double-inclusion
win32/configure.js:
* Added support for the LZMA compression option
win32/Makefile.{bcb,mingw,msvc}:
* Added appropriate bits to support WITH_LZMA=1
* Install the header files under $(INCPREFIX)\libxml2\libxml instead of
$(INCPREFIX)\libxml, to mirror the install location on Unix+Autotools
xml2-config.in:
* @MODULE_PLATFORM_LIBS@ (usually "-ldl") needs to be in there in order for
`xml2-config --libs` to provide a complete set of dependencies
xmllint.c:
* Use HAVE_MMAP instead of the less-explicit HAVE_SYS_MMAN_H
In xmlInitParser, both __xmlGlobalInitMutexLock and xmlInitGlobals are
called before xmlInitThreads, and both use pthread symbols.
__xmlGlobalInitMutexLock does so directly, without checking if the symbol
exists, and xmlInitGlobals calls xmlNewMutex, which correctly depends on
libxml_is_threaded... except libxml_is_threaded is still -1 by then...
And again, when releasing the global mutex in __xmlGlobalInitMutexUnlock,
the pthread function is called directly.
The patch changes the initialization order and make sure the functions
are available before calling them
