Koenig) + - Added license in Makefile.PL (Alexandr Ciornii) + - Makefile.PL also searches for expat in C:/lib/Expat-2.0.0 (Alexandr Ciornii) + - No longer uses variable named 'namespace' in Expat.xs (Jeff Hunter) + +2.33 + - Fixed Tree style (grantm) + - Fixed some non-utf8 stuff in DTDs (patch in XML::DOM tarball) + +2.32 + - Memory leak fix (Juerd Waalboer). + - Added windows-1252 encoding + - Styles moved to separate .pm files to make loading faster and + ease maintainence + - Don't load IO::Handle unless we really need to + +2.31 Tue Apr 2 13:39:51 EST 2002 + - Ilya Zakharevich <ilya@math.ohio-state.edu> and + Dave Mitchell <davem@fdgroup.com> both provided patches to + fix problems module had with 5.8.0 + - Dave Mitchell also made some UTF-8 related fixes to the test suite. +2.30 Thu Oct 5 12:47:36 EDT 2000 + - Get rid of ContentStash global. Not that big a deal looking it up + everytime and gets rid of a potential threading problem. + - Switch to shareable library version of expat from sourceforge + (i.e. no longer include expat source and require that libexpat + be installed) + - Bob Tribit <btribit@traffic.com> demonstrated a fix for problems + in compiling under perl 5.6.0 with 5.005 threading. + - Matt Sergeant <matt@sergeant.org> discovered a typo ('IO::Handler' + instead of 'IO::Handle') in Expat.pm that caused IO::Handle objects + to be treated as strings instead of handles. + - Matt Sergeant also provided a patch to allow tied handles to work + properly in calls to parse. + - Eric Bohlman <ebohlman@netcom.com> reported a failure when + incremental parsing and external parsing were used together. + Need to give explicit package when calling Do_External_Parse + from externalEntityRef otherwise fails when called through ExpatNB. +2.29 Sun May 21 21:19:45 EDT 2000 + - In expat, notation declaration handler registration wasn't + surviving through external entity references. + - Chase Tingley <tingley@sundell.net> discovered that text + accumulation in the Stream style wasn't working across processing + instructions and recommended the appropriate fix. + - Jochen Wiedmann <jochen.wiedmann@softwareag.com>, noted that + you couldn't use ExpatNB directly because it wasn't setting + the protective _State_ variable. Now doing this in the + parse_more method of ExpatNB. + - At the suggestion of Grant Hopwood <hopwoodg@valero.com>, now + calling the env_proxy method on the LWP::UserAgent in the LWP + external entity handler when it's created to set any proxies + from environment variables. + - Grant McLean, Matt Sergeant (& others I may have missed) noted that + loading the LWP & URI modules slowed startup of the module, even + if the application didn't need it. The default LWP handler is now + dynamicly loaded (along with LWP & URI modules) the first time an + external entity is referenced. Also provided a NoLWP option to + XML::Parser that forces the file based external entity handler. + - Fixed allocation errors in element declaration patches in expat + - The Expat base method now works, even before expat starts parsing. + - Changed the canonical script to take an optional file argument. + - Enno Derksen <enno@att.com> reported that the attlist handler + was not returning NOTATION type attlist information. + - Michel Rodriguez <mrodrigu@ieee.org>, noted that the constructor + for XML::Parser objects no longer checked for the existence of + applications installed external entity handlers before installing + the default ones. + - Burkhard Meier <burkhard.meier@ixos.de> sent in a fix for + compiler directives in Expat/Makefile.PL for Win32 machines. + A change in 5.6.0 caused the old conditional to fail. + - Forgot to document changes to the Entity declaration handler: + there is an additional "IsParam" argument that indicates whether + or not the entity is a parameter entity. This information is + no longer passed on in the name. + - Ben Low <ben@snrc.uow.edu.au> reported an undefined macro with + version 5.004_04. +2.28 Mon Mar 27 21:21:50 EST 2000 + - Junked local (Expat.xs) declaration parsing and patched expat to + handle XML declarations, element declarations, attlist declarations, + and all entity declarations. By eliminating both shadow buffers and + local declaration parsing in Expat.xs, I've eliminated the two most + common sources of serious bugs in the expat interface. + o thus fixed the segfault and parse position bugs reported by + Ivan Kurmanov <iku@fnmail.com> + o and the doctype bug reported by Kevin Lund + <Kevin.Lund@westgroup.com> + o The element declaration handler no longer receives a string, + but an XML::Parser::ContentModel object that represents the + parsed model, but still looks like a string if referred to as + a string. This class is documented in the XML::Parser::Expat + pod under "XML::Parser::ContentModel Methods". + o The doctype declaration handler no longer receives the internal + subset as a string, but in its place a true or undef value + indicating whether or not there is an internal subset. Also, + it's called prior to processing either the internal or external + DTD subset (as suggested by Enno Derksen <enno@att.com>.) + o There is a new DoctypeFin handler that's called after finishing + parsing all of the DOCTYPE declaration, including any internal + or external DTD declarations. + o One bit of lossage is that recognized_string, original_string, + and default_current no longer work inside declaration handlers. + - Added a handler that gets called after parsing external entities: + ExternEntFin. Suggested by Jeff Horner <jhorner@netcentral.net>. + - parsefile, file_ext_ent_handler, & lwp_ext_ent_handler now all + set the base path. This problem has been raised more than once + and I'm not sure to whom credit should be given. + - The file_ext_ent_handler now opens a file handle instead of + reading the entire entity at once. + - Merged patches supplied by Larry Wall to (for perl 5.6 and beyond) + tag generated strings as UTF-8, where appropriate. + - Fixed a bug in xml_escape reported by Jerry Geiger <jgeiger@rios.de>. + It failed when requesting escaping of perl regex meta-characters. + - Laurent Caprani <caprani@pop.multimania.com> reported a bug in the + Proc handler for the Debug style. + - <chocolateboy@usa.net> sent in a patch for the element index + mechanism. I was popping the stack too soon in the endElement fcn. + - Jim Miner <jfm@winternet.com> sent in a patch to fix a warning in + Expat.pm. + - Kurt Starsinic pointed out that the eval used to check for string + versus IO handle was leaving $@ dirty, thereby foiling higher + level exception handlers + - An expat question by Paul Prescod <paul@prescod.net> helped me + see that exeptions in the parse call bypass the Expat release method, + causing memory leaks. + - Mark D. Anderson <mda@discerning.com> noted that calling + recognized_string from the Final method caused a dump. There are + a bunch of methods that should not be called after parsing has + finished. These now have protective if statements around them. + - Updated canonical utility to conform to newer version of Canonical + XML working draft. +2.27 Sat Sep 25 18:26:44 EDT 1999 + - Corrected documentation in Parser.pm + - Deal with XML_NS and XML_BYTE_ORDER macros in Expat/Makefile.PL + - Chris Thorman <chris@thorman.com> noted that "require 'URI::URL.pm'" + in Parser.pm was in error (should be "require 'URI/URL.pm'") + - Andrew McNaughton <andrew@scoop.co.nz> noted "use English" and + use of '$&' slowed down regex handling for whole application, so + they were excised from XML::Parser::Expat. + - Work around "modification of read-only value" bug in perl 5.004 + - Enno Derksen <enno@att.com> reported that the Doctype handler + wasn't being called when ParseParamEnt was set. + - Now using Version 19990728 of expat, with local patches. + - Got rid of shadow buffer + o thus fixed the error reported by Ashley Sanders + <a.sanders@mcc.ac.uk> + o and removed ExpatNB limitations that Peter Billam + <music@pjb.com.au> noted. + - Vadim Konovalov <vkonovalov@lucent.com> had a problem compiling + for multi-threading that was fixed by changing Perl_sv_setsv to + sv_setsv. + - Added new Expat method: skip_until(index) + - Backward incompatible change to method xml_escape: to get former + behavior use $xp->xml_escape($string, '>', ...) + - Added utility, canonical, to samples +2.26 Sun Jul 25 19:06:41 EDT 1999 + - Ken Beesley <ken.beesley@xrce.xerox.com> discovered that + declarations in the external subset are not sent to registered + handlers when there is no internal subset. + - Fixed parse_dtd to work when entity values or attribute defaults + are so large that they might be broken across multiple calls to + the default handler. + - For lwp_ext_ent_handler, use URI::URL instead of URI so that old + 5.004 installations will work with it. +2.25 Fri Jul 23 06:23:43 EDT 1999 + - Now using Version 1990709 of expat. No local patches. + - Numerous people reported a SEGV problem when running t/cdata + on various platforms and versions of perl. The problem was + introduced with the setHandlers change. In some cases an + un-initialized value was being returned. + - Added an additional external entity handler, lwp_ext_ent_handler, + that deals with general URIs. It is installed instead of the + "file only" handler if the LWP package is installed. +2.24 Thu Jul 8 23:05:50 EDT 1999 + - KangChan Lee <dolphin@comeng.chungnam.ac.kr> supplied the + EUC-KR encoding map. + - Enno Derksen <enno@att.com> forwarded reports by Jon Eisenzopf + <eisen@pobox.com> and Stefaan Onderbeke <onderbes@bec.bel.alcatel.be> + about a core dump using XML::DOM. This was due to a bug in the + prolog parsing part of XML::Parser. + - Loic Dachary <loic@ceic.com> discovered that changing G_DISCARD to + G_VOID introduced a small memory leak. Changed G_VOID back to + G_DISCARD. + - As suggested by Ben Holzman <bholzman@earthlink.net>, the + setHandlers methods of both Parser and Expat now return lists that + consist of type, handler pairs that correspond to the input, but + the handlers returned are the ones that were in effect prior to + the call. + - Now using Version 19990626 of expat with a local patch (provided + by James Clark.) + - Added option ParseParamEnt. When set to a true value, parameter + entities are parsed and the external DTD is read (unless standalone + set to "Yes" in document). +2.23 Mon Apr 26 21:30:28 EDT 1999 + - Fixed a bug in the ExpatNB class reported by Gabe Beged-Dov + <begeddov@jfinity.com>. The ErrorMessage attribute wasn't + being initialized for ExpatNB. This should have been done in + the Expat constructor. + - Applied patch provided by Nathan Kurz <nate@valleytel.net> to + fix more perl stack manipulation errors in Expat.xs. + - Applied another patch by Nathan to change perl_call_sv flag + from G_DISCARD to G_VOID for callbacks, which helps performance. + - Murata Makoto <murata@apsdc.ksp.fujixerox.co.jp> reported a + problem on Win32 platforms that only showed up when UTF-16 was + being used. The needed call to binmode was added to the parsefile + methods. + - Added documentation for release method that was added in release + 2.20 to Expat pod. (Point raised by <mookie@undef.com>) + - Now using Version 19990425 of expat. No local patches. + - Added specified_attr method and made ineffective the is_defaulted + method. +2.22 Sun Apr 4 11:47:25 EDT 1999 + - Loic Dachary <loic@ceic.com> reported a core dump with a small + file with a comment that wasn't properly closed. Fixed in expat + by updating positionPtr properly in final call of XML_Parse. + (Reported to & acknowledged by James Clark.) + - Made more fixes to Expat.xs position calculation. + - Loic Dachary <loic@ceic.com> provided patches for fixing a + memory growth problem with large documents. (Garbage collection + wasn't happening frequently enough.) + - As suggested by Gabe Beged-Dov <begeddov@jfinity.com>, added + a non-blocking parse mechanism: + - Added parse_start method to XML::Parser, which returns a + XML::Parser::ExpatNB object. + - Added XML::Parser::ExpatNB class, which is a subclass of + Expat and has the additional methods parse_more & parse_done + - Made some performance tweaks as suggested by performance thread + on perl-xml discussion list. [With negligible results] + - Tried to clarify Tree style structure in Parser pod +2.21 Sun Mar 21 17:42:04 EST 1999 + - Warren Vik <wvik@whitebarn.com> provided patches for a bug + introduced with the is_defaulted method. It manifested itself + by bogusly reporting duplicate attributes. + - Now using latest expat from ftp://ftp.jclark.com/pub/test/expat.zip, + Version 19990307. (Plus any patches in Expat/expat.patches.) + - As suggested by Tim Bray, added an xml_escape method to + Expat. + - Murray Nesbitt <murray@activestate.com> had build problems + on Win32 that were solved by swapping 2 include files in + Expat.xs + - Added following Expat namespace methods: + new_ns_prefixes + expand_ns_prefix + current_ns_prefixes + - Fixed memory handling in recognized_string method to get rid + of "Attempt to free unreferenced scalar" bug. +2.20 Sun Feb 28 15:35:52 EST 1999 + - Fixed miscellaneous bugs in xmlfilter. + - In the default external entity handler, prepend the base only + for relative URLs. + - Chris Nandor <pudge@pobox.com> provided patches for building + on Macintosh. + - As suggested by Matt Sergeant <Matthew.Sergeant@eml.ericsson.se>, + added the finish method to Expat. + - Matt also provided a fix to a bug he discovered in the Streams + style. + - Fixed a parse position bug reported by Enno Derksen <enno@att.com> + that was affecting both original_string and position_in_context. + - Fixed a gross memory leak reported by David Megginson, + <david@megginson.com>: there was a circular reference to the Expat + object and the internal end handler for context was not freeing + element names after they were removed from the context stack. + - Now using expat Version 19990109 + (Plus any patches in Expat/expat.patches) + - Added is_defaulted method to Expat to tell if an attribute + was defaulted. (Requested by Enno Derksen for XML::DOM.) + - Matt Sergeant <Matthew.Sergeant@eml.ericcson.se> reported that + the XML::Parser parse methods weren't propagating array context + to the Final handler. Now they are. + - Fixed more memory leaks (again reported by David Megginson). + The SVs pointing to the handlers weren't being reclaimed when + the callback vector was freed. + - Added the element_index method to Expat. +2.19 Sun Jan 3 11:23:45 EST 1999 + - When the recognized string is long enough, expat uses multiple + calls to reportDefault.

This returns the untranslated + string (i.e. original encoding) that caused current event. + - Alberto Accomazzi <alberto@cfa0.harvard.edu> sent in more patches + for perl5.005_54 incompatibilities. + - Alberto also fingered a nasty memory bug in Expat.xs that arose + sometimes when you registered a declaration handler but no + default handler. It would give you a "Not a CODE reference" + error in a place that wasn't using any CODE references. + - <schinder@pobox.com> reported a problem with compiling expat + on a Sun 4 due to non-exsitance of memmove on that OS. Provided + a workaround in Makefile.PL + - Now using expat Version 19981231 from James Clark's test directory. + - Made patch to this version in order to support original_string + (see Expat/expat.patches.) + - Added CdataStart and CdataEnd handlers to expat. +2.18 Sun Dec 27 07:39:23 EST 1998 + - Alberto Accomazzi <alberto@cfa0.harvard.edu> pointed out that + the DESTROY sub in the new XML::Parser::Encinfo package was + pointing to the wrong package for calling FreeEncoding. + - Tarang Kumar Patel <mombasa@ptolemy.arc.nasa.gov> reported + the mis-declaration of an integer as unsigned in the + convert_to_unicode function in Expat.xs. + - Glenn R. Kronschnabl <grk@arlut.utexas.edu> reported a problem + with ExternEnt handlers when using parsefile. Turned out to be + an unmatched ENTER; SAVETMPS pair that screwed up the Perl stack. + - Tom Hughes <tom@compton.demon.co.uk> reported that the fix I put + in for the swith to PL_sv.. names failed with 5.0005_54, since + these became real variables instead of macros. Switched to just + checking the PATCHLEVEL macro. + - Yoshida Masato <yoshidam@inse.co.jp> provided the EUC-JP encodings + (the corresponding XML files are in XML::Encoding 1.01 or later.) + - With the advice of MURATA Makoto <murata@apsdc.ksp.fujixerox.co.jp>, + removed the Shift_JIS encoding and replaced it with 4 variations + he provided.

The entity + handler sees the name beginning with '%' if it's a parameter + entity declaration. + - Nigel Hutchison <nwoh@software-ag.de> pointed out that stream.t + wasn't portable off Unix systems. Replaced with portable version. + - Fixed bug reported by Enno Derksen <enno@att.com>: + XML Declaration was firing off both XMLDecl handler *and* Default + handler. + - Added option NoExpand to Expat to turn off expansion of entity + references when a default handler is set. +2.15 Tue Oct 20 14:50:11 EDT 1998 + - In Expat's parse method, account for undefined previous + record separators. + - Simplify a couple of Expat methods. + - Re-ordered Changes entries to put latest changes first. + - In XML::Parser::new, set Handlers if not already set + - New Handler (XMLDecl) for handling XML declarations + - New Handler (Doctype) for handling DOCTYPE declarations + - New Handler (Entity) for handling ENTITY declarations in + the internal subset. + - New Handler (Element) for handling ELEMENT declarations in + the internal subset. + - New Handler (Attlist) for handling ATTLIST declarations in + the internal subset. + - Documented new handlers + - Added t/decl.t to test new handlers +2.14 Sun Oct 11 22:17:15 EDT 1998 + - Always use method calls for streams. + - Use perl's input_record_separator to find delimiter (i.e. each + "line" is an entire XML doc with delimiter appended) + - Deal with line being longer than buffer. +2.13 Thu Oct 8 16:58:39 EDT 1998 + - Fixed a major oops in Expat.xs where I was trying to decrement + a refcnt on an unallocated SV, leading to a segment violation. + (Why did this show up on HPUX but not Linux?) +2.12 Thu Oct 8 00:05:10 EDT 1998 + - Incorporated fix to t/astress.t from <fletch@phydeaux.org> (Mike + Fletcher). + - Change to xmlstats from <dblack@candle.superlink.net> (David + Alan Black) + - Access Handlers_Setters in Expat and Handler_Types in Parser + through object reference (following admonition in perltoot + about class data.) + - Added Stream_Delimiter option to Expat. + - In the parse_stream function in Expat.xs, if we either have a + Stream_Delimiter or if there's no file descriptor, use method + calls instead. For Stream_Delimiter in particular, the function + now uses the getline method so it can check for the delimiter + without consuming stuff past the delimiter from the stream. +2.11 Sun Oct 4 22:15:53 EDT 1998 + - Swapped out local patch for expat and swapped in James Clark's + patch. + - Pass on all Parser attributes (other than those excluded by + Non_Expat_Options) to the instance of Expat created at parse time. + - New method for Expat: generate_ns_name + - Split test.pl into t/*.t and change Makefile.PL so we don't do a + useless descent into Expat subdir for testing. + - Stop the numeric warning for eq_name and namespace method. +2.10 Fri Sep 25 18:36:46 EDT 1998 + - Uses expat Version 19980924 + (with local patch - see Expat/expat/xmlparse/xmlparse.c.diff) + - Use newSVpvn when PERL_VERSION >= 5.005 + - Completed xmlfilter + - Added support for namespace processing: + o Namespaces option to XML::Parser and XML::Parser::Expat + o Two new methods in Expat: + namespace - to return namespace associated with name + eq_name - compare 2 names for equality across namespaces. + - Use expat's new SetDefaultHandlerExpand instead of SetDefaultHandler + so that entity expansion may continue even if the default handler + is set. + - Moved test.pl back up main level and changed to work with XML::Parser + - Added tests for namespaces +2.09 Fri Sep 18 10:33:38 EDT 1998 + - Fixed errors that caused -w to fret in XML::Parser. + - Fixed depth method in XML::Parser::Expat + - There were a few places in Expat.xs where garbage strings may + have been returned due to the expat library giving us zero-length + strings. Fixed by using a local version of newSVpv where length + means length, even when zero. + - The default handler setter in Expat.xs, was inappropriately setting + cbv->dflt_sv when there was a null handler. +2.08 Thu Sep 17 11:47:13 EDT 1998 + - Make XML::Parser higher-level re-usable parser objects. Old object + now becomes XML::Parser::Expat. + - The XML::Parser object now supports the style mechanism very close + to that in the 1.0 version. +2.07 Wed Sep 9 11:03:43 EDT 1998 + - Added some samples (xmlcomments & xmlstats) + - Now requires 5.004 (due to sv_catpvf) + - Changed Makefile.PL to allow automatic manification + - Added a test that reads xml spec (to check buffer boundary errors) +2.06 Tue Sep 1 10:40:41 EDT 1998 + - Fixed the methods current_line, current_byte, and current_column + - Added some tests +2.05 Mon Aug 31 15:29:42 EDT 1998 + - Made Makefile.PL changes suggested by Murray Nesbitt + <murray@ActiveState.com> to support building on Win32 + and for making PPM binaries. + - Added method parse + - Changed parsestring and parsefile to use new parse method + - Deprecated parsestring method + - Improved error handling in the ExternEnt handler +2.04 Wed Aug 26 13:25:01 EDT 1998 + - Uses expat Version 1.0 of August 14, 1998 + - Some document changes + - Changed dist section in Makefile.PL + - Added ExternEnt handler + - Added tests for ExternEnt +2.03 Fri Aug 21 17:19:26 EDT 1998 + - Changed InitEncoding to ProtocolEncoding. Default to none. + Pass null string to expat's ParserCreate when there is no + ProtocolEncoding. + - Fixed bug in parsefile & parsestring where they were referring + to an ErrorContext *method* instead of a field. + - Fixed position_in_context bugs: + -- 'last' in do {} while (); + -- insert newline before pointer when no following newline + in buffer. + - Added some additional tests +2.02 Thu Aug 20 14:05:08 EDT 1998 + - Fixed parsefile problem reported by + "Robert Hanson" <robertha@zenweb.com>, using a modification of + his suggested fix. + - Responded to problem reported by + Bart Schuller <schuller+perl-xml@lunatech.com> + by pre-expanding parts of the XML_UPD macro to avoid confusing + some versions of gcc. + - Changed the constructor to take the option InitEncoding, which + gets passed to the ParserCreate call.
