e8fb3d63	2024-01-02T17:45:54	parser: Convert some "internal errors" to meaningful codes
9912c369	2024-01-02T17:23:59	SAX2: Enforce size limit in xmlSAX2Text with XML_PARSE_HUGE
661ef936	2024-01-02T18:50:59	valid: Fix some error codes
5cb4b05c	2024-01-02T17:16:22	parser: Lower maximum entity nesting depth Limit entity nesting depth to 20 or 40 with XML_PARSE_HUGE. Change error code to XML_ERR_RESOURCE_LIMIT.
0821efc8	2024-01-02T18:33:57	encoding: Check whether encoding handlers support input/output The "HTML" encoding handler doesn't support input which could lead to a wrong error report.
85f99023	2024-01-02T17:52:43	parser: Fix buffer size checks 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.
a2cc7f5f	2024-01-02T17:02:21	parser: Set depth limit to 2048 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.
875bb084	2023-09-07T03:25:45	parser: Implement xmlCtxtSetOptions 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.
33ec407a	2023-09-07T03:33:09	parser: Always prefer option members over bitmask 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.
22fd571f	2023-09-06T22:15:20	parser: Don't modify SAX2 handler if XML_PARSE_SAX1 is set 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.
37c6618b	2023-12-30T02:50:34	parser: Rework parsing of attribute and entity values 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.
4dcc2d74	2024-01-02T14:04:44	save: Output U+FFFD replacement characters 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.

a1ed589b	2023-12-29T23:12:06	parser: Avoid unwanted expansion of parameter entities 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.
16b0dbc1	2023-12-29T18:47:30	parser: Fix XML_ERR_UNSUPPORTED_ENCODING errors Commit 45157261 added the check in the wrong place. Also allow unsupported encoding in xmlNewInputInternal. Fixes #654.
e45a4d71	2023-12-29T00:00:21	io: Always forward IO errors to global handler The HTTP module raises errors without context. This won't be fixed, so send them to the global error handler.
a73483ed	2023-12-29T00:22:02	parser: Remove extraneous error message This is not an "internal error" but some other error reported elsewhere.
7e0bbbc1	2023-12-27T18:33:30	parser: New input API 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.
45157261	2023-12-27T21:30:13	parser: Downgrade XML_ERR_UNSUPPORTED_ENCODING to warning If the actual encoding is UTF-8 or ASCII, we don't want to fail.
24b7144f	2023-12-27T15:50:58	parser: More refactoring of entity parsing Remove xmlCreateEntityParserCtxtInternal. Rework xmlNewEntityInputStream.
d3ceea0b	2023-12-27T15:18:09	parser: Fix encoding handling in xmlParserInputBufferCreateIO Don't pass encoding to xmlParserInputBufferCreateIO but use xmlSwitchEncoding to make sure that the encoding sticks.
d025cfbb	2023-12-27T03:53:24	parser: Always copy content from entity to target. 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.
6337ff79	2023-12-27T03:29:13	parser: Simplify control flow in xmlParseReference

4f14fe9c	2023-12-26T02:44:38	parser: Remove remaining ctxt->instate checks Now ctxt->instate is only used for push parser states.
d944a415	2023-12-26T02:10:35	parser: Fix in-parameter-entity and in-external-dtd checks 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.

ecfbcc8a	2023-12-25T04:33:00	parser: Rework general entity parsing Don't create a new parser context but reuse the existing one. This exposes bug #601 in a more obvious way.
c2ef78f7	2023-12-24T23:56:57	io: Fix close error handling There's no way to report error codes from closing an output buffer yet.

0bef93bf	2023-12-23T04:03:41	io: More refactoring and unescaping fixes Merge Windows wrappers into relevant functions. Remove more unnecessary unescaping. Merge OpenW into Open functions. Use unbuffered IO for output.
331dcd62	2023-12-23T01:40:54	error: Reenable full error reports to default handler This should make console output include some information about nodes again. Note that this extra information must be disabled if a custom generic error handler was set. Many downstream test suites rely on this behavior.
c1bddd4c	2023-12-23T01:09:17	parser: Mark 'length' member of xmlParserInput as unused
955c177f	2023-12-23T00:58:36	parser: Stop using 'directory' struct member This was only used as a pointless fallback for URI resolution.
60841beb	2023-12-25T18:31:22	parser: Make XML_IO_NETWORK_ATTEMPT behave as before Always reported to generic error, not to parser context for backward compatibility. Several downstream test suites rely on this behavior.
a2693410	2023-12-23T00:35:30	io: Move some code from xmlIO.c to parserInternals.c Move everything related to parser contexts to parserInternals.c.
8ab1b122	2023-12-23T00:00:15	Fix filename and URI handling Many strings are passed to the library that could be either URIs or filesystem paths. We now assume that strings are a URI if they contain the substring "://". This means that they have a scheme and an authority. Otherwise, URI resolution wouldn't make much sense. Fix xmlBuildURI to work with filesystem paths. If the base URI doesn't contain "://" it is treated as filename. The resolved URI is unescaped, appended and the result is normalized. Rewrite xmlNormalizePath to handle Windows quirks. All special handling for Windows paths is removed in xmlCanonicPath. If the path looks like an URI, only escape characters allowed in Legacy Extended IRIs. Make xmlPathToURI only call xmlCanonicPath. Theh additional round-trip through URI parser and serializer seems useless. Add a helper function xmlConvertUriToPath in xmlIO.c which checks for file URIs and unescapes them. Always process strings with xmlCanonicPath in xmlLoadExternalEntity. This should be harmless now. Should help with #334, #387, #611.
28913232	2023-12-22T23:58:43	uri: Clean up special parsing modes Add function to handle unreserved check. Give flags meaningful names. Add support to allow ucschars from Legacy Extended IRIs.
6e3a2ac6	2023-12-22T21:38:50	xinclude: Rework xml:base fixup The xml:base fixup was broken in more complex cases. Also avoid parsing and building the included URI multiple times.

e8de3401	2023-12-22T02:57:19	parser: Also set document properties when push parsing Add new function xmlFinishDocument which invokes the endDocument SAX handler and sets the document's properties.
c73de050	2023-12-23T04:50:47	include: Move non-generated parts from xmlversion.h.in xmlexports.h originally only included symbol visibility macros but it's a good place for other macros as well.

0a658c0f	2023-12-20T23:53:19	io: Don't use "-" to read from stdin To implement this feature on such a low level is a disaster waiting to happen. Remove these checks from the IO code and move them to xmllint. Note that the serialization API will still treat "-" as stdout.

1ef35663	2023-12-19T19:36:35	io: Always use unbuffered input 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).
7e14c05d	2023-12-19T17:05:08	io: Fix detection of compressed streams Make sure that we don't try to open uncompressed streams with a compression handler in copying mode.
7e511f35	2023-12-19T15:41:37	io: Pass error codes from xmlFileOpenReal to xmlNewInputFromFile 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.
b2dbcc43	2023-12-19T13:33:59	io: Rework default callbacks Register a dummy callback struct for default callbacks. Handle them in a separate function which will later allow to return meaningful error codes.
531d06ad	2023-12-18T22:48:24	error: Stop printing some errors by default 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.

parser: New input API 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.

Fix filename and URI handling Many strings are passed to the library that could be either URIs or filesystem paths. We now assume that strings are a URI if they contain the substring "://". This means that they have a scheme and an authority. Otherwise, URI resolution wouldn't make much sense. Fix xmlBuildURI to work with filesystem paths. If the base URI doesn't contain "://" it is treated as filename. The resolved URI is unescaped, appended and the result is normalized. Rewrite xmlNormalizePath to handle Windows quirks. All special handling for Windows paths is removed in xmlCanonicPath. If the path looks like an URI, only escape characters allowed in Legacy Extended IRIs. Make xmlPathToURI only call xmlCanonicPath. Theh additional round-trip through URI parser and serializer seems useless. Add a helper function xmlConvertUriToPath in xmlIO.c which checks for file URIs and unescapes them. Always process strings with xmlCanonicPath in xmlLoadExternalEntity. This should be harmless now. Should help with #334, #387, #611.

error: Stop printing some errors by default 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.
