2010-04-01 version 1.1:
* Bugfix: protobuf-perlxs 1.0 could not be compiled with a protobuf
version earlier than 2.2.0.
* Bugfix: to_hashref() lower-cased field names. Thanks to Nacho
Gutierrez for the patch.
2010-03-09 version 1.0:
* Bugfix: generated code for enums with --perlxs-package set was
incorrect.
2010-03-09 version 0.9:
* Issue 6: optimize_for = LITE_RUNTIME causes compilation errors
* Bugfix: Added AC_LANG([C++]) to configure.ac, to fix broken
detection of protobuf headers.
* Compatibility: Added -lpthread, for linking with more recent
versions of protobuf libraries.
* Feature: Added support for the --perlxs-package option (not yet
documented). Use this to override the package option
value in a .proto file during Perl/XS code generation.
2009-05-28 version 0.8:
* Issue 5: eval { } doesn't catch protobuf->pack() fatal errors
2009-01-23 version 0.7:
* Issue 4: String and bytes types are truncated when using NUL
characters due to char * handling in generated XS code
(Patch contributed by Jason Hord).
* Bugfix: Packed message that were multiples of 8 bytes long did
not have their Perl string length set correctly.
* Added an example (string_bytes) to check regressions on the
bugs fixed in this release.
* Added an example (package) showing the use of multiple top-level
messages in the same package namespace.
2009-01-20 version 0.6:
* Issue 3: Off-by-one error in XS generated code for initializing
repeated elements in ->new() (Patch contributed by
Jason Hord).
* Separated generated POD documentation from .pm files into .pod
files.
* Eliminated the need to generate (and use) typemap files.
* Performance enhancement: pack() uses a ZeroCopyStream to avoid
an extra string copy. The performance of packing large messages
is roughly twice as good as it was before.
* Added an example that packs and unpacks a large message. Found
that the performance of populating, packing, and unpacking a
message with 10 strings of 2 MB each was:
Implementation pack unpack pack + unpack
--------------------------------------------------------------
Storable freeze/thaw 0.052991 0.032896 0.085887
protoxs/NoZeroCopy 0.067012 0.023046 0.090058
protoxs/ZeroCopy 0.042966 0.020175 0.063141
All three methods are quite fast, but protoxs/ZeroCopy wins by a
significant margin, with an overall pack + unpack throughput of
~316 MB/s, compared with 232 MB/s for Storable and ~222 MB/s for
protoxs/NoZeroCopy.
2009-01-14 version 0.5:
* Bugfix: generated code had numerous issues. Patch contributed
by Seth Daniel.
* New example illustrating use of protobuf types.
2009-01-09 version 0.4:
* New method in generated classes:
my @fields = $message->fields();
@fields is an array of strings. Each string corresponds to the
name of a class member. Contributed by Seth Daniel.
* New method in generated classes:
my $hashref = $message->to_hashref();
$hashref is a complete, Data::Dumper-style recursive dump of the
message and all of its embedded messages.
* Extended methods copy_from() and merge_from():
In addition to their pre-existing ability to copy and merge a
message instance from another instance of the same message type,
these methods may also be used with a hashref argument, of the
sort that might be generated by the to_hashref() method. This
makes it easy to build messages from hashrefs:
my $message = Foo->new;
$message->copy_from({ bar => 'baz', bat => 'qux' });
Note that for both of these methods, failure to provide a
hash value for any of the required fields of a message is
silently ignored, for the following reasons:
1) In some cases, the user may wish to build the message one
part at a time via merge_from() of multiple different
hashrefs, ultimately yielding a complete message instance.
2) In any case, missing required fields will be reported when
the user unsuccessfully attempts to serialize the message.
* Extended message constructors
It is now possible to instantiate a message with a hashref as
the sole constructor argument:
my $message = Foo->new({ bar => 'baz', bat => 'qux' });
This is equivalent to:
my $message = Foo->new;
$message->copy_from({ bar => 'baz', bat => 'qux' });
It is also possible to instantiate a message with a scalar as
the sole constructor argument:
my $packed = Foo->new({ bar => 'baz'})->pack;
my $foo2 = Foo->new($packed);
In this case, the scalar is interpreted as a packed message
of the given type.
2008-11-19 version 0.3:
* Issue 1: undef symbols in OS/X (need to link with libprotobuf).
* Issue 2: Embedded message code generated with Perl class name.
2008-10-01 version 0.2:
* Removed CamelCase of class and enum names.
2008-09-19 version 0.1:
* Initial version.
