f19a9510	2023-12-10T17:50:22	parser: Report malloc failures 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.
c082ef46	2023-08-09T16:59:36	parser: Stop switching to ISO-8859-1 on encoding errors Use U+FFFD Replacement Character if invalid UTF-8 is encountered in recovery mode. Also rewrite xmlNextChar and xmlCurrentChar. Fixes #598.
eb69c1d3	2023-10-02T12:16:05	parser: Fix initialization of namespace data Move initialization to xmlInitSAXParserCtxt. Also add missing XML_HIDDEN to xmlParserNsFree. Fixes #597.
e0dd330b	2023-09-29T00:18:44	parser: Use hash tables to avoid quadratic behavior Use a hash table to lookup namespaces by prefix. The hash table stores an index into the namespace table. Auxiliary data for namespaces is stored in a separate array along the main namespace table. Use a hash table to verify attribute uniqueness. The hash table stores an index into the attribute table. Reuse hash value from the dictionary to avoid computing them twice. See #346.
f1c1f5c6	2023-08-16T19:43:02	parser: Revert change to doc->encoding Fixes #579.
ec7be506	2023-08-08T15:19:46	parser: Rework encoding detection Introduce XML_INPUT_HAS_ENCODING flag for xmlParserInput which is set when xmlSwitchEncoding is called. The parser can use the flag to reliably detect whether an encoding was already set via user override, BOM or other auto-detection. In this case, the encoding declaration won't be used to switch the encoding. Before, an inscrutable mix of ctxt->charset, ctxt->input->encoding and ctxt->input->buf->encoder was used. Introduce private helper functions to switch encodings used by both the XML and HTML parser: - xmlDetectEncoding which skips over the BOM, allowing to remove the BOM checks from other encoding functions. - xmlSetDeclaredEncoding, replacing htmlCheckEncodingDirect, which warns about encoding mismatches. If users override the encoding, store the declared instead of the actual encoding in xmlDoc. In this case, the actual encoding is known and the raw value from the doc is more useful. Also use the input flags to store the ISO-8859-1 fallback state. Restrict the fallback to cases where no encoding was specified. (The fallback is only useful in recovery mode and these days broken UTF-8 is probably more likely than ISO-8859-1, so it might eventually be removed completely.) The 'charset' member of xmlParserCtxt is now unused. The 'encoding' member of xmlParserInput is now unused. The 'standalone' member of xmlParserInput is renamed to 'flags'. A new parser state XML_PARSER_XML_DECL is added for the push parser.

04d1bedd	2023-03-21T13:08:44	parser: Rework shrinking of input buffers Don't try to grow the input buffer in xmlParserShrink. This makes sure that no memory allocations are made and the function always succeeds. Remove unnecessary invocations of SHRINK. Invoke SHRINK at the end of DTD parsing loops. Shrink before growing.
b167c731	2023-03-14T14:42:36	parser: Fix short-lived regression causing infinite loops Fix 3eb6bf03. We really have to halt the parser, so the input buffer gets reset.
2099441f	2023-03-13T17:51:13	parser: Stop calling xmlParserInputShrink Introduce xmlParserShrink which takes a parser context to simplify error handling.
3eb6bf03	2023-03-12T16:47:15	parser: Stop calling xmlParserInputGrow Introduce xmlParserGrow which takes a parser context to simplify error handling.
ccb6d544	2022-11-27T02:09:27	Hide internal functions These functions were never declared in public headers, so it should be safe to hide them. Fixes #139.
0f568c0b	2022-08-26T01:22:33	Consolidate private header files 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.
