Remove explicit integer casts as final operation
- in assignments
- when passing arguments
- when returning values
Remove casts
- to the same type
- from certain range-bound values
The main motivation is that these explicit casts don't change the result
of operations and only render UBSan's implicit-conversion checks
useless. Removing these casts allows UBSan to detect cases where
truncation or sign-changes occur unexpectedly.
Document some explicit casts as truncating and add a few missing ones.
Private functions were previously declared
- in header files in the root directory
- in public headers guarded with IN_LIBXML
- in libxml.h
- redundantly in source files that used them.
Consolidate all private header files in include/private.
This code has been broken and deprecated since version 2.6.0, released
in 2003. Because of a bug in commit 961b535c, DOCBparser.c was never
compiled since 2012. I couldn't find a Debian package using any of its
symbols, so it seems safe to remove this module.
If libz or liblzma are detected with pkg-config, AC_CHECK_HEADERS must
not be run because the correct CPPFLAGS aren't set. It is actually not
required have separate checks for LIBXML_ZLIB_ENABLED and HAVE_ZLIB_H.
Only check for LIBXML_ZLIB_ENABLED and remove HAVE_ZLIB_H macro.
Fixes bug 764657, bug 787041.
Make sure that all parameters and return values of list callback
functions exactly match the callback function type. This is required
to pass clang's Control Flow Integrity checks and to allow compilation
to asm.js with Emscripten.
Also change the `user` parameter type from `const void *` to `void *`.
* HTMLparser.c c14n.c debugXML.c entities.c nanohttp.c parser.c
testC14N.c uri.c xmlcatalog.c xmllint.c xmlregexp.c xpath.c:
fix unused variables, or unneeded increments as well as a couple
of space issues
* runtest.c: check for NULL before calling unlink()
* c14n.c include/libxml/c14n.h: adds support for C14N 1.1,
new flags at the API level
* runtest.c Makefile.am testC14N.c xmllint.c: add support in CLI
tools and test binaries
* result/c14n/1-1-without-comments/* test/c14n/1-1-without-comments/*:
add a new batch of tests
* doc/apibuild.py doc/elfgcchack.xsl: revamped the elfgcchack.h
format to cope with gcc4 change of aliasing allowed scopes, had
to add extra informations to doc/libxml2-api.xml to separate
the header from the c module source.
* *.c: updated all c library files to add a #define bottom_xxx
and reimport elfgcchack.h thereafter, and a bit of cleanups.
* doc//* testapi.c: regenerated when rebuilding the API

include/libxml/xmlerror.h: Setting up the framework for structured
error reporting, touches a lot of modules, but little code now
the error handling trail has been cleaned up.

nanohttp.c parser.c parserInternals.c relaxng.c tree.c uri.c
xmlmemory.c xmlreader.c xmlregexp.c xpath.c xpointer.c
include/libxml/globals.h include/libxml/xmlmemory.h: added
xmlMallocAtomic() to be used when allocating blocks which
do not contains pointers, add xmlGcMemSetup() and xmlGcMemGet()
to allow registering the full set of functions needed by
a garbage collecting allocator like libgc, ref #109944

testDocbook.c threads.c tree.c valid.c xmlIO.c xmllint.c xmlmemory.c
xmlreader.c xmlregexp.c xmlschemas.c xmlschemastypes.c xpath.c:
code cleanup, especially the function comments.
* tree.c: fixed a small bug when freeing nodes which are XInclude ones.
Daniel
* DOCBparser.c HTMLparser.c c14n.c entities.c list.c
parser.c parserInternals.c xmlIO.c: get rid of all the
perror() calls made in the library execution paths. This
should fix both #92059 and #92385
Daniel
* c14n.c include/libxml/c14n.h: fixed one more c14n + namespaces corner case from new Merlin's test suite and added a callback that will be used to improve xmlsec performance

testC14N.c Makefile.am: added merlin-c14n-two.tar.gz tests for
c14n/exc-c14n and slightly modified test script to handle
these test cases
* c14n.c: fixed bugs for complicated nodes set (namespace
without node and others from merlin-c14n-two.tar.gz)
* include/libxml/xpathInternals.h win32/dsp/libxml2.def.src
win32/libxml2.def.src: "opened" xmlXPathNodeSetFreeNs() function
for xmlsec performance patch
* xpath.c: fixed self::node() for namespaces and attributes
* c14n.c: propagating xpath ancesstors node fix to c14n plus small performance improvement to reduce number of mallocs * xpath.c: fixed ancestors axis processing for namespace nodes
