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.
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.
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.
Unfortunately, it's long-standing behavior for libxml2 to print all
reported errors to stderr by default. This default behavior is now
partially disabled. If no error handler is set, only parser and
validation errors are passed to a generic error handler or printed to
stderr. Other errors are still available via xmlGetLastError and can be
captured with a structured error handler.
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.
xmlParserInputBufferCreateMem must make a copy of the buffer.
This fixes a regression from 2.11 which could cause reads from freed
memory depending on the use case.
Undeprecate xmlParserInputBufferCreateStatic which can avoid copying
the whole buffer.
Fix many places where malloc failures aren't reported.
Make xmlErrMemory public. This is useful for custom external entity
loaders.
Introduce new API function xmlSwitchEncodingName.
Change the way how we store whether the the parser is stopped. This used
to be signaled by setting ctxt->instate to XML_PARSER_EOF which was
misdesigned and error-prone. Set ctxt->disableSAX to 2 instead and
introduce a macro PARSER_STOPPED. Also stop to remove parser inputs in
xmlHaltParser. This allows to remove many checks of ctxt->instate.
Introduce xmlErrParser to handle errors if a parser context is
available.
This regressed in commit e0dd330b.
Also fixes a long-standing issue where namespaces from default
attributes weren't added if they match an existing namespace.
Fixes#643.
Setting these deprecated globals hasn't had an effect for a long time.
Make them constants. This reduces the size of per-thread storage from
~700 to ~250 bytes.
Set the dictionary for newDoc in xmlParseBalancedChunkMemoryRecover.
This is a long-standing bug which was masked by
- xmlParseBalancedChunkMemoryRecover changing the document of the root
node. This is a really bad idea, resulting in a mismatch between
ctxt->myDoc and ctxt->node->doc.
- SAX2.c preferring ctxt->node->doc over ctxt->myDoc until commit
a31e1b06.
Fixes#641.
Partial revert of cb927e85 fixing CRLFs not incrementing the line
number.
This requires to rework xmlParseQNameHashed. The original implementation
prompted the change to xmlCurrentChar which really shouldn't modify the
'cur' pointer as side effect. But the NEXTL macro relies on this
behavior.
Ultimately, we should reintroduce the change to xmlCurrentChar and fix
the NEXTL macro. This will lead to single CRs incrementing the line
number as well which seems more consistent.
Fixes#628.
