Always use what the old implementation called the "IO" allocation
scheme, allowing to move the content pointer past the initial
allocation. This is inexpensive and allows efficient shrinking.
Optimize xmlBufGrow, reusing shrunken memory as much as possible.
Simplify xmlBufAdd.
Make xmlBufBackToBuffer return an error on overflow.
Make "size" exclude the terminating NULL byte.
Always provide an initial size.
Reintroduce static buffers.
Remove xmlBufResize and several other functions.
Only use structured error handlers for parser, Schemas and RelaxNG
contexts. Also use structured error handler for XInclude context.
Remove TODO macro.
Introduce xmlCtxtSetErrorHandler allowing to set a structured error for
a parser context. There already was the "serror" SAX handler but this
always receives the parser context as argument.
Start to use xmlRaiseMemoryError.
Remove useless arguments from memory error functions. Rename
xmlErrMemory to xmlCtxtErrMemory.
Remove a few calls to xmlGenericError.
Remove support for runtime entity debugging.
Make sure that xmlCharEncInput, xmlParserInputBufferPush and
xmlParserInputBufferGrow set the correct error code in the
xmlParserInputBuffer. Handle errors when calling these functions.
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.
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.
