This is an internal function which isn't really usable without some
hacks. See WebKit/Chromium trying to recreate the effects of
xmlDetectSAX2 manually, for example.
Make xmlParseContent perform late initialization and check whether the
content was fully parsed.
Also rename xmlDetectSAX2 and document why it's needed.
This is a useful function to get a verbose error report.
Allows to remove duplicated code from runtest.c. Also reactivate check
for schema parser failures.
Don't test size of remaining data. This causes false positives with
memory buffers.
Also impose XML_MAX_HUGE_LENGTH limit when parsing with XML_PARSE_HUGE.
Deeply nested documents can cause performance problems, so the nesting
depth should always be limited to a reasonable value.
Also remove the global xmlParserMaxDepth setting which isn't thread-safe
and seems unused.
Surprisingly, some options can only be enabled with xmlCtxtUseOptions
and it's impossible to unset them. Add a new API function
xmlCtxtSetOptions which sets or clears all options.
Finally document all parser options.
Make sure to synchronize option bits and struct members.
If an option has an extra member in xmlParserCtxt, it takes precedence
over the value from the options bitmask. Fix a few places where this was
ignored.
It's a bad idea to modify members of the SAX handler struct for option
state management. Ideally, ctxt->options should be the preferred source
of truth.
Don't use a separate function to handle "complex" attributes. Validate
UTF-8 byte sequences without decoding. This should improve performance
considerably when parsing multi-byte UTF-8 sequences.
Use a string buffer to avoid unnecessary allocations and copying when
expanding entities.
Normalize attribute values in a single pass while expanding entities.
Be more lenient in recovery mode.
If no entity substitution was requested, validate entities without
expanding. Fixes#596.
Also fixes#655.
This degrades more gracefully and helps to diagnose errors.
We stop raising errors for now, since there's no way to report malloc
failures during error handling yet.
Remove PE handling from xmlSkipBlankChars and add a separate version
that handles PEs. Only call xmlSkipBlankCharsPE when parsing DTD
constructs. This should make sure that PEs don't get expanded
accidentally, for example in text declarations.
Provide a new set of functions to create xmlParserInputs. These can be
used for the document entity or from external entity loaders.
- Don't require xmlParserInputBuffer.
- All functions take a base URI.
- All functions take an encoding as string.
- xmlNewInputURL also takes a public ID.
- xmlNewInputMemory takes a size_t.
- Optimization hints for memory buffers.
Improve documentation.
Only call xmlInitParser before allocating a new parser context.
Call xmlCtxtUseOptions as early as possible.
Make sure that references from IDs are updated.
Note that if there are IDs with the same value in a document, the last
one will now be returned. IDs should be unique, but maybe this should be
addressed.
Use in ctxt->input->entity instead of ctxt->inputNr to determine whether
we are inside a parameter entity.
Stop using ctxt->external to check whether we're in an external DTD.
This is signaled by ctxt->inSubset == 2.
Today I learned that the TSCII character encoding [1] can blow up the
size of text 12 times when converted to UTF-8:
$ printf '\x82' |iconv -f TSCII -t UTF-8 |hexdump -C
00000000 e0 ae b8 e0 af 8d e0 ae b0 e0 af 80
0000000c
