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.
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.
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.
Before, we often used unbuffered input via the lzma or gzip handlers,
more or less inadvertently.
Change the default file handlers from buffered (stdc FILE) to unbuffered
(POSIX fds).
This allows to report the reason why opening a file failed to the parser
context and improve error messages. Now we can also remove the stat call
before opening a file.
Introduce xmlXIncludeSetErrorHandler allowing to set a structured error
handler for an XInclude context and forwarding errors from parser.
Remove arguments from memory error handlers.
Use xmlRaiseMemoryError.
Introduce xmlXPathSetErrorHandler allowing to set a structured error
handler for an XPath context.
Remove arguments from memory error handlers.
Use xmlRaiseMemoryError.
Remove TODO, STRANGE and CHECK_CTXT macros.
Remove remaining uses of xmlGenericError.
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.
Introduce xmlStrVASPrintf, trying to handle buggy snprintf
implementations.
Introduce xmlSetError to set errors atomically.
Introduce xmlUpdateError to set an error, fixing up node, file and line.
Introduce helper function xmlRaiseMemoryError.
Make legacy error handlers call xmlReportError, avoiding checks in
xmlVRaiseError.
Remove fragile support for getting file and line info from XInclude
nodes.
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.
Fix many places where malloc failures aren't reported.
Rework XPath object cache to store free objects in a linked list to
avoid allocating an additional array. Remove some unneeded object pools.
Don't ignore malloc failures in xmlRaiseError and xmlCopyError.
Don't print filename if context has no input.
Introduce xmlVRaiseError taking a va_list.
Fix many places where malloc failures aren't reported.
Make some API function return an error code. Changing the return type
from void to int is technically an ABI break but should be safe on most
platforms.
- xmlNodeSetContent
- xmlNodeSetContentLen
- xmlNodeAddContent
- xmlNodeAddContentLen
- xmlNodeSetBase
Introduce new API functions that return a separate error code if a
memory allocation fails.
- xmlNodeGetAttrValue
- xmlNodeGetBaseSafe
- xmlGetNsListSafe
Introduce private functions xmlTreeEnsureXMLDecl and xmlSplitQName4.
Don't report low-level errors to the global error handler.
Fix tree
Introduce xmlGetNsListSafe
Fix tree
Introduce a new API function xmlAddIDSafe that returns a separate error
code if a memory allocation fails.
Store a pointer to the ID struct in xmlAttr so attributes can be
freed without allocating memory. It's impossible to report malloc
failures in deallocation code.
Fix places where malloc failures aren't reported.
Introduce a new API function xmlPatternCompileSafe that returns a
separate error code if a memory allocation fails.
Fix places where malloc failures aren't reported.
Introduce new API function xmlAddEntity that returns separate error
codes.
Don't invoke global error handler for low-level errors which should be
handled by higher layers.
Invalid redelcaration warnings will be fixed later.
Introduce new API functions that return a separate error code if a
memory allocation fails.
- xmlOpenCharEncodingHandler
- xmlLookupCharEncodingHandler
Fix a few places where malloc failures weren't reported.
Fix many places where malloc failures weren't reported, for example
after calling xmlStrdup.
Introduce new public API functions that return a separate error code if
a memory allocation fails:
- xmlParseURISafe
- xmlBuildURISafe
- xmlBuildRelativeURISafe
Update the fuzzer to check whether malloc failures are reported.
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.
The long-term plan is to remove the built-in HTTP client. There are
still a few downstream projects that use libxml2's client for other
purposes. These users should get deprecation warnings now.
