Checking whether the context is close to the parent context by hardcoding
250 is not portable (I noticed tests were failing on Morello since the value
is 288 there due to pointers being 128 bits). Instead we should ensure
that the XML_VCTXT_USE_PCTXT flag is not set in cases where the user data
is not actually a parser context (or ideally add a separate field but that
would be an ABI break.
From what I can see in the source, the XML_VCTXT_USE_PCTXT is only set if
the userData field points to a valid context, and if this is not the case
the flag should be cleared when changing userData rather than relying on
the offset between the two. Looking at the history, I think
d7cb33cf44aa688f24215c9cd398c1a26f0d25ff fixed most of the need for this
workaround, but it looks like there are a few more locations that need
updating; This commit changes two more places to set/clear/copy the
XML_VCTXT_USE_PCTXT flag, so this heuristic should not be needed anymore.
I've also drop two = NULL assignment in xmllint since this is not needed
after a call to memset().
There was also an uninitialized vctxt.flags (and other fields) in
`xmlShellValidate()`, which I've fixed by adding a memset() call.
We never want translation of newlines when reading files, so it should
be safe to always specify "rb". On sane platforms, the "b" flag is
simply ignored.
From what I can tell, some really early Cygwin versions from around
1998-2000 used to erroneously define _WIN32. This was eventually fixed,
but these days, the `defined(_WIN32) && !defined(__CYGWIN__)` idiom is
unnecessary.
Now, we only check for __CYGWIN__ in xmlexports.h when deciding whether
to use __declspec.
xmlMemSetup must be called before initializing the parser, otherwise
some data structures will be allocated with system malloc instead of
our custom allocator. This throws off built-in memory debugging and
sanitizers.
Call htmlCtxtUseOptions to make sure that names aren't stored in
dictionaries.
Note that this issue only affects xmllint using the HTML push parser.
Fixes#230.
Make sure that truncated UTF-8 sequences don't cause an out-of-bounds
array access.
Thanks to @SuhwanSong and the Agency for Defense Development (ADD) for
the report.
Fixes#178.
Starting with commit da35eeae, xmllint uses the xmlNodeDump API to dump
XPath nodes. Make sure not to access node->doc which doesn't work with
namespace nodes.
Separate nodes in a node-set with newlines and always add a terminating
newline. This is a breaking change but the old behavior of dumping text
nodes without separator was mostly useless.
Also use buffered I/O when dumping node-sets.
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.
