Revision history for Perl extension XML::Parser.

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 <[e-mail]> and
	  Dave Mitchell <[e-mail]> 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 <[e-mail]> demonstrated a fix for problems
	  in compiling under perl 5.6.0 with 5.005 threading.
	- Matt Sergeant <[e-mail]> 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 <[e-mail]> 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 <[e-mail]> discovered that text
	  accumulation in the Stream style wasn't working across processing
	  instructions and recommended the appropriate fix.
	- Jochen Wiedmann <[e-mail]>, 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 <[e-mail]>, 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 <[e-mail]> reported that the attlist handler
	  was not returning NOTATION type attlist information.
	- Michel Rodriguez <[e-mail]>, 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 <[e-mail]> 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 <[e-mail]> 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 <[e-mail]>
	  o and the doctype bug reported by Kevin Lund
	    <[e-mail]>
	  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 <[e-mail]>.)
	  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 <[e-mail]>.
	- 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 <[e-mail]>.
	  It failed when requesting escaping of perl regex meta-characters.
	- Laurent Caprani <[e-mail]> reported a bug in the
	  Proc handler for the Debug style.
	- <[e-mail]> sent in a patch for the element index
	  mechanism. I was popping the stack too soon in the endElement fcn.
	- Jim Miner <[e-mail]> 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 $@ dirty, thereby foiling higher
	  level exception handlers
	- An expat question by Paul Prescod <[e-mail]> helped me
	  see that exeptions in the parse call bypass the Expat release method,
	  causing memory leaks.
	- Mark D. Anderson <[e-mail]> noted that calling
	  recognized_string from the Final method caused a dump. There are
	  a bunch of methods that should not be called after parsing has
	  finished. These now have protective if statements around them.
	- Updated canonical utility to conform to newer version of Canonical
	  XML working draft.
2.27 Sat Sep 25 18:26:44 EDT 1999
	- Corrected documentation in Parser.pm
	- Deal with XML_NS and XML_BYTE_ORDER macros in Expat/Makefile.PL
	- Chris Thorman <[e-mail]> noted that "require 'URI::URL.pm'"
	  in Parser.pm was in error (should be "require 'URI/URL.pm'")
	- Andrew McNaughton <[e-mail]> noted "use English" and
	  use of '$&' 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 <[e-mail]> 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
	     <[e-mail]>
	  o  and removed ExpatNB limitations that Peter Billam
             <[e-mail]> noted.
	- Vadim Konovalov <[e-mail]> 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 <[e-mail]> 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 <[e-mail]> supplied the
	  EUC-KR encoding map.
	- Enno Derksen <[e-mail]> forwarded reports by Jon Eisenzopf
	  <[e-mail]> and Stefaan Onderbeke <[e-mail]>
	  about a core dump using XML::DOM. This was due to a bug in the
	  prolog parsing part of XML::Parser.
	- Loic Dachary <[e-mail]> 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 <[e-mail]>, 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
	  <[e-mail]>. The ErrorMessage attribute wasn't
	  being initialized for ExpatNB. This should have been done in
	  the Expat constructor.
	- Applied patch provided by Nathan Kurz <[e-mail]> 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 <[e-mail]> 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 <[e-mail]>)
	- 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 <[e-mail]> 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 <[e-mail]> provided patches for fixing a
	  memory growth problem with large documents. (Garbage collection
	  wasn't happening frequently enough.)
	- As suggested by Gabe Beged-Dov <[e-mail]>, 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 <[e-mail]> 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 <[e-mail]> 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
