In some cases, for example when using encoders, the read callback was
set to NULL, in other cases it was set to xmlInputReadCallbackNop.
xmlGROW only tested for xmlInputReadCallbackNop, resulting in errors
when parsing large encoded content from memory.
Always use a NULL callback for memory buffers to avoid ambiguities.
Fixes#262.
When using xmlreader, XPointer expressions in XIncludes simply cannot
work. Expressions can reference nodes which weren't parsed yet or which
were already deleted.
After fixing nested XIncludes, we reference includes which were parsed
previously. When streaming, these nodes could have been deleted, leading
to use-after-free errors.
Disallow XPointer expressions and truncate the include table in
streaming mode.
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.
Somewhat misleadingly, the DOC_DISABLE directive only disabled warnings.
Now we really stop the documentation generator from indexing.
This results in additional warnings for xmlThrDef* functions. This should
be fixed by documenting or deprecating them.
Commit 4fd69f3e fixed handling of '<' characters not followed by an
ASCII letter. But a '<!' sequence followed by invalid characters should
be treated as bogus comment and skipped.
Fixes#380.
Add a new configuration flag that controls whether the outdated support
for XPointer locations (ranges and points) is enabled.
--with-xptr-locs # Autotools
LIBXML2_WITH_XPTR_LOCS # CMake
The latest spec for what it essentially an XPath extension seems to be
this working draft from 2002:
https://www.w3.org/TR/xptr-xpointer/
The xpointer() scheme is listed as "being reviewed" in the XPointer
registry since at least 2006. libxml2 seems to be the only modern
software that tries to implement this spec, but the code has many bugs
and quality issues.
The flag defaults to "off" and support for this extensions has to be
requested explicitly. The relevant API functions are deprecated.
- Remove xmlSwitchToEncodingInt which was basically just a wrapper
around xmlSwitchInputEncodingInt.
- Simplify xmlSwitchEncoding.
- Improve error handling in xmlSwitchInputEncodingInt.
- Deprecate xmlSwitchInputEncoding.
These functions shouldn't be part of the public API. Most init
functions are only thread-safe when called from xmlInitParser. Global
variables should only be cleaned up by calling xmlCleanupParser.
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.
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.
These functions are only needed internally for validation.
xmlGetRefs is inherently unsafe because the ref table isn't updated
if attributes are removed (unlike the ids table).
None of the Ubuntu 20.04 packages depending on libxml2 use any of these
functions (except xmlFreeRefTable in libxslt), so it seems perfectly
safe to deprecate them.
Remove xmlIsRef and xmlRemoveRef from the Python bindings.
Use a bitmask instead of magic values to
- keep track whether the validation context is part of a parser context
- keep track whether xmlValidateDtdFinal was called
This allows to add addtional flags later.
Note that this deliberately changes the name of a public struct member,
assuming that this was always private data never to be used by client
code.
This file was undocumented and never used anywhere. Maybe users were
supposed to rename this file to xmlversion.h manually. These days, both
CMake and win32/configure.js generate xmlversion.h from xmlversion.h.in,
just like the Autotools build.
