Revision history for Perl extension XML::Parser.
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. Fixed recString handler in Expat.xs to
deal with this properly.
- Added original_string method to Expat. 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. He also provided an explanatory message.
- Added the recognized_string method to Expat, deprecating
default_current.
- Now using expat Version 19981122 from James Clark's test directory
(this fixes another bug with external entity reference handlers)
- Added a default external entity handler that only accesses file:
based URLs.
2.17 Sun Dec 13 17:39:58 EST 1998
- Replaced uses of malloc, realloc, and free with New, Renew,
and Safefree respectively
- In Expat.pm, fixed methods in_element and within_element to
work correctly with namespaces.
- xmlfilter - Substitute quoted equivalents for special characters
in attribute values.
- position_in_context was off by one line when position was at
the end of line.
- For the context methods in Expat.pm, do the right thing when
the context list is empty.
- Added methods xpcroak and xpcarp to Expat.
- Alberto Accomazzi <alberto@cfa0.harvard.edu> noted that perl
releases 5.005_5* (the pre 5.006 development versions) won't
accept sv_undef (and related constants) anymore and we have
to switch to PL_sv_...
- Alberto also reported a warning in the newer versions of
IO::Handle about input_record_separator not being treated on
a per-handle basis.
- Fixed bug that Jon Udell <udell@top.monad.net> reported in
Stream style: Text handler most of the time didn't see proper
context.
- Added XML::Parser::Expat::load_encoding function and support
for external encodings.
2.16 Tue Oct 27 22:27:33 EST 1998
- Fixed bug reported by Enno Derksen <enno@att.com>:
Now treats parameter entity declarations correctly. 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. When not given, defaults
to UTF-8.
- Added method position_in_context
- Added Constructor option ErrorContext and added reporting of
errors in context.
2.01 Wed Aug 19 11:42:42 EDT 1998
- Added methods:
default_current, base, current_line, current_column,
current_byte, context
- Added some tests
- parsestring and parsefile now croak if they're re-used
- Filled in some documentation
2.00 Mon Aug 17 12:01:33 EDT 1998
- repackaged with James Clark's most recent expat
- changed to an API closer to expat
1.00 March 1998
- Larry Wall's original version
