-------------------------
Version 0.76 (2011-04-11)
-------------------------
* it looks like I've found the source of the test failures reported
in cpan #56369; this version is an attempt to fix the problem, but
without fully understanding it -- if a windows guru can explain to
me why setjmp() deadlocks if the jmp_buf structure was allocated
through Perl's API (New, Newz, etc), I'd really appreciate it
-------------------------
Version 0.75 (2011-04-10)
-------------------------
* fix cpan #63381 / perl #79854: make sure warnings cause a cache
file not to be used (thanks to Andreas König for reporting this)
* fix bug in unpack where the code would attempt to create an array
with negative size when running out of input data
* make sure elf.PL reads/writes in binary mode (thanks to רחלי מרל
for finding this problem)
-------------------------
Version 0.74 (2009-04-18)
-------------------------
* fix sourcification of flexible array members (triggered by cpan
#45105; thanks to Alexander Ost for being persistent in his
attempt to convince me that there's a bug in sourcify)
-------------------------
Version 0.73 (2009-03-16)
-------------------------
* fix META.yml generation with newer versions of ExtUtils::MakeMaker
* work around an include path handling bug present in some versions
of Test::Harness
-------------------------
Version 0.72 (2009-03-15)
-------------------------
* fix cpan #43119: patch to allow Convert::Binary::C to build
with GCC 4.4.x (thanks to Alex Lancaster for providing a patch)
-------------------------
Version 0.71 (2008-04-15)
-------------------------
* added new 'StdCVersion' and 'HostedC' options for configuring
the predefined macros of the preprocessor
* fix debugging build with development version of Perl
-------------------------
Version 0.70 (2007-12-24)
-------------------------
-- released without changes --
----------------------------
Version 0.69_01 (2007-12-08)
----------------------------
* fix UV generation on platforms where NVs don't preserve
UVs (e.g. amd64) and perl doesn't know about UVs (<5.6.0)
* make the test suite more noisy when something goes wrong
-------------------------
Version 0.69 (2007-12-06)
-------------------------
* fix: unpack would return garbage when an unpack hook
causes the perl stack to be reallocated
* make ccconfig handle blanks in paths correctly
* slightly improve ELF parser example
* fix debug format strings
-------------------------
Version 0.68 (2007-06-25)
-------------------------
* allow #pragma pack(0) to reset to default alignment,
just like #pragma pack
* add checks for invalid #pragma pack() arguments
-------------------------
Version 0.67 (2006-12-29)
-------------------------
* bleeding edge perl versions don't have SVt_PVBM anymore,
which broke compilation of cbc/util.c
-------------------------
Version 0.66 (2006-11-02)
-------------------------
* fix a bug in the parser that accidentially allowed
qualified enum specifiers as unnamed compound members
* update test suite for better coverage of recent
compiler features and bitfields
-------------------------
Version 0.65 (2006-08-27)
-------------------------
* fix compilation issues with perls configured with
threads and debugging; these issues were caused by
a buggy implementation of the assert() macro in the
5.8 series of perl
* fix compilation issues with HP compiler on itanium
systems
* fix: hooks for the same type were not re-entrant
(i.e. you could not pack/unpack the same type
within a hook registered for that type)
* fix: passing sparse hashes or arrays to pack() in
combination with pack hooks was causing an assertion
* fix an integer promotion bug in the preprocessor
* add better support for C99-style array declarator
* fix enumerator handling: it was impossible to reuse
the name of an enumerator as an identifer
* ccconfig fix: macros defined to the empty string
were not properly detected
----------------------------
Version 0.64_02 (2006-03-24)
----------------------------
* struct members are now treated more Cish than before
* added experimental Dimension tag
* cleaned up some internals
----------------------------
Version 0.64_01 (2006-02-27)
----------------------------
* added new methods to interface with the preprocessor:
o the 'defined' method tests if a macro is defined
o the 'macro_names' method returns a list of all
defined macro names
o the 'macro' method returns macro definitions
* added 'Defines' option for 'sourcify' method; with
this option turned on, macro definition are also
sourcified
* the speed of the 'sourcify' method has been greatly
improved
* add a new pod coverage test
* fix a pod2usage call in elf.pl example
* improve warning when trying to pack references into
format tagged types
* make the module and some basic tests compatible with
perl 5.004
* the native() function/method now also supports the
'UnsignedChars' and 'UnsignedBitfields' properties
* the 'threads' feature is deprecated and will be removed
in a future relase
-------------------------
Version 0.64 (2006-01-16)
-------------------------
* fix version handling in *.pm files
* don't index bin/elf.PL
* upgrade ppport.h
----------------------------
Version 0.63_01 (2006-01-09)
----------------------------
* fix: using the Format tag on bitfield members now throws
an exception
* added experimental ByteOrder tag
* added ELF parser example
* improve internals
o better encapsulation of the pack/unpack code
o avoid unneccessary computations
expressions in the lexer code of the ucpp preprocessor
could be optimized, making the preprocessor more than
10% faster on x86 platforms; this means that parsing
should be about 7% faster now
* improve test coverage
-------------------------
Version 0.63 (2005-12-29)
-------------------------
* fix a problem with the test suite when run in a directory
that contains whitespace characters
* (hopefully) fix the no_index problem in the META.yml by
replacing "dir" with "directory"
-------------------------
Version 0.62 (2005-12-01)
-------------------------
* fixed a bug in unpack() that would cause an error when
repeatedly passing a substr() as the data argument; this
is not a critical bug, because there's no silent failure
-------------------------
Version 0.61 (2005-10-27)
-------------------------
* fix Makefile.PL / META.yml
-------------------------
Version 0.60 (2005-10-26)
-------------------------
* fixed: the byte order setting was not correctly handed
to the bitfield layouter when using configure() before
using parse(); since that's what C::B::C::Cached does,
C::B::C::Cached could be using the wrong byte order for
bitfields
* the deprecated methods add_hooks(), delete_hooks() and
delete_all_hooks() have been removed
* silence some warnings with newer gcc versions
* start moving test suite to use Test::More
* bundle Test, Test::More and Test::Harness for older
perl versions
* extend compatibility down to perl 5.005
-------------------------
Version 0.59 (2005-06-13)
-------------------------
* fixed: dying hooks no longer leak memory
* added new 'UnsignedBitfields' option
* removed 'Bitfields are unsupported' warning
* documented bitfield support
* the usual cleanups and corrections
----------------------------
Version 0.58_01 (2005-05-23)
----------------------------
* bitfields are now supported; since bitfield implementations
differ from compiler to compiler (sometimes significantly),
the bitfield layouting engine can be exchanged at runtime;
bitfield support is, however, still considered experimental
* the memory used by internal data structures as well
as the number of malloc/free calls has been reduced
by about 15 percent; besides saving memory, this also
makes parsing and cloning a bit faster
* the whole pack()/unpack() engine was re-doing the work
that has previously been done by the compound layouter;
this redundancy has been removed, making the code more
readable (and a little bit faster)
* the compound layouter implementation has been separated
and can now be exchanged at runtime (which is currently
unused as there's only one implementation)
* the bison parser is now making use of the %destructor
feature introduced recently; this makes the parser code
a lot easier to read and maintain, and makes the parser
a bit faster; you need at least bison-2.0a to regenerate
the files
* when packing 'string' numbers, the 0b... syntax is now
supported for binary numbers
* ccconfig's interface and internals have been updated
* ccconfig now has a lot more options that hopefully allow
you to test compilers with strange commandline interface
* ccconfig is now more robust against compiler failures
* lots of minor tweaks and fixes
-------------------------
Version 0.58 (2005-02-21)
-------------------------
* there's now a mailing list; see the documentation or
README for details
* new tag() method provides a generic way of tagging
properties such as hooks to types
* the hooks methods are deprecated and will be removed
in a future release (new interface is provided through
tag() / untag())
* completely restructured the XS/C internals, since C.xs
was getting way too large; the code should be a lot
more modular and organized now
* make the preprocessor handle (read: ignore) any #ident
directives (problem spotted by Ronnie Kelly)
* use faster preprocessor tokenizer routine
* ccconfig: add --output-file and --output-format options
* fix invalid read bug when redefining a macro with trailing
whitespace (spotted by valgrind)
* make sure pack() returns null-terminated strings; not doing
so can confuse the regex engine
* strip redundant warnings from enum/compound/typedef methods
* fix deep recursion in llex() that causes bus error on hpux
(this should fix the activestate test failures)
* make util / ucpp use Perl's memory allocation functions
(this should fix problems with -Dusethreads and -Dusemymalloc)
* as usual, more tests and more docs
-------------------------
Version 0.57 (2004-11-23)
-------------------------
* allow empty initializers (spotted by Mike Lamb)

-------------------------
* allow empty member declaration lists
* minor doc fixes
-------------------------
Version 0.55 (2004-08-22)
-------------------------

request native alignment and compound alignment
* prefix compile-time defaults with CBC_ and document them
* upgrade ppport.h
* minor cleanups
-------------------------
Version 0.54 (2004-07-01)
-------------------------
* improved hooks features
* changed handling of autogenerated files that has been
causing trouble with crappy archiving tools
* minor bugfixes
-------------------------

wrong initialization strings for unnamed unions
* fixed a systematic bug that caused sourcify to return
invalid C code in a few special cases
-------------------------
Version 0.51 (2004-03-23)
-------------------------
* added method chaining for add_hooks, delete_hooks and
delete_all_hooks
* fixed some bugs when using substr() with pack and unpack
* documentation fixes and updates
-------------------------
Version 0.50 (2004-03-22)
-------------------------
* added support for flexible array members and incomplete
types

user-defined packing/unpacking
* ucpp is now reentrant, thus there's no more locking of
parse/parse_file

* improved ccconfig's detection of ability to compile
object/executable files
* lots of minor bugfixes and code cleanups
-------------------------
Version 0.49 (2003-11-24)
-------------------------
* fixed build problem on multi-threaded 5.6.x perls by
removing irrelevant code from ppport.h
* changed error reporting: preprocessor errors are no
longer only warnings
(this fixes an issue with Convert::Binary::C::Cached
creating an empty cache file if none of the #include'd
files could be found)
* fixed some error/warnings reporting problems with
Convert::Binary::C::Cached
* minor cleanups
-------------------------
Version 0.48 (2003-11-03)
-------------------------
* added new 'OrderMembers' option: this option allows you
to tie all hashes returned by the unpack method to either
Tie::Hash::Indexed or Tie::IxHash, thus preserving the
order of compound members when e.g. dumping the hashes or
iterating through their keys/values
* slightly improved performance for pack method
* added META.yml
* lots of code cleanups
* small bugfixes
-------------------------
Version 0.47 (2003-09-11)
-------------------------
* enhanced behaviour of def() method
* added new pod test
* fixed some buglets
-------------------------

and caused problems with almost all versions of perl
* fixed: sizeof() could return garbage when used on array
types
* fixed bogus warning generated by pack when explicitly
passing 'undef'
* improved warning messages generated by pack
* added error when using offsetof on bitfields
* added new initializer method
* the offset argument to the member method is now optional;
without the offset argument, a list of all possible
members is returned
* code cleanups
-------------------------
Version 0.42 (2003-06-23)
-------------------------
* added new 'ieeefp' feature
* new floating point conversion code to support both IEEE
and non-IEEE sytems
o on machines using the IEEE format to store floating
point numbers, you can pack/unpack arbitrary byteorder
floating point values for all supported native sizes
o on machines not using the IEEE format, packing and
unpacking of floating point values is restricted to
the types natively available
* floating point conversion checks and warnings have been
improved
* added floating point format detection to ccconfig
* some code cleanups
-------------------------
Version 0.41 (2003-06-10)
-------------------------
* added support for gcc's asm syntax
* some cleanups
-------------------------
Version 0.40 (2003-04-20)
-------------------------
* same as 0.13, just to make CPAN(?:PLUS|-indexer)? happy
-------------------------
Version 0.13 (2003-04-20)
-------------------------
* changed behaviour of member method in list context
o doesn't return the member's type any longer
o returns all matching members instead, if multiple
members match the given offset
o this change is NOT backward compatible
o to get the old behaviour, turn
($member, $typeof) = $c->member( $type, $offset );
into
$member = $c->member( $type, $offset );
$typeof = $c->typeof( $type.$member );
* fixed lots of memory leaks resulting from using sv_dec()
where SvREFCNT_dec() should have been used instead
* fixed memory leak when object construction fails
* fixed sourcify for enums in special cases
* fixed segfault in debugging mode
* removed lots of limitations and fixed lots of bugs when
dealing with member expressions

* added dwimmy handling of offset suffixes
* added basic type support for many methods
* allowed basic types to be used without parsing any code

-------------------------
Version 0.04 (2002-11-27)
-------------------------
* support for 64-bit data types on all platforms
* additional data types
o long long
o long double
* new methods
o clean -- cleaning an object
o clone -- cloning an object
o depencencies -- retrieve an object's dependencies
o sourcify -- emit an object's parsed data as C source
* changed method behaviour
o configure
- The 'HashSize' option has been removed. I didn't like
it anyway, and since the hash tables are now growing
automatically, it's completely useless.
o def
- Instead of undef, 0 and 1, the def method will now return
undef, '' (the empty string) or the kind of the type you
passed as an argument, e.g. 'typedef' or 'union'.
* added method behaviour
o configure
- Calls to configure (and other configuration methods) can
be chained together when they're 'set' method calls.
o parse, parse_file
- All method calls that have no return value will return a
reference to their object, so method chaining is possible.
o pack, unpack, sizeof, offsetof, member
- These methods now can all operate on compound members, i.e.
you could say $obj->sizeof( 'type.foo.x' ).
o member
- The member method now can optionally return the type of the
requested member.
* new Convert::Binary::C::Cached module
o cached Convert::Binary::C objects
o identical interface
o can speed up parsing by up to 10 - 20 times
