|
||||
perl5419delta - what is new for perl v5.41.9
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This document describes differences between the 5.41.8 release and the 5.41.9
|
||||
release.
|
||||
|
||||
If you are upgrading from an earlier release such as 5.41.7, first read
|
||||
L<perl5418delta>, which describes differences between 5.41.7 and 5.41.8.
|
||||
|
||||
=head1 Core Enhancements
|
||||
|
||||
=head2 Lexical method declaration using C<my method>
|
||||
|
||||
Like C<sub> since Perl version 5.18, C<method> can now be prefixed with the
|
||||
C<my> keyword. This declares a subroutine that has lexical, rather than
|
||||
package visibility. See L<perlclass> for more detail.
|
||||
|
||||
=head2 Lexical method invocation operator C<< ->& >>
|
||||
|
||||
Along with the ability to declare methods lexically, this release also permits
|
||||
invoking a lexical subroutine as if it were a method, bypassing the usual
|
||||
name-based method resolution by name.
|
||||
|
||||
Combined with lexical method declaration, these two new abilities create the
|
||||
effect of having private methods.
|
||||
|
||||
=head1 Incompatible Changes
|
||||
|
||||
=head2 Switch and Smart Match operator reinstated
|
||||
|
||||
The "switch" feature and the smartmatch operator, C<~~>, were introduced in
|
||||
v5.10. Their behavior was significantly changed in v5.10.1. When the
|
||||
"experiment" system was added in v5.18.0, switch and smartmatch were
|
||||
retroactively declared experimental. Over the years, proposals to fix or
|
||||
supplement the features have come and gone.
|
||||
|
||||
They were deprecated in Perl v5.38.0 and scheduled for removal in Perl
|
||||
5.42.0, and entirely removed in Perl 5.41.3.
|
||||
|
||||
After some discussion these have been re-instated.
|
||||
|
||||
Using them no longer produces a deprecation warning.
|
||||
|
||||
Switch itself still requires the C<switch> feature, which is enabled
|
||||
by default for feature bundles from v5.9.5 through to v5.34. Switch
|
||||
remains disabled in feature bundles 5.35 and later, but can be
|
||||
separately enabled:
|
||||
|
||||
# no switch here
|
||||
use v5.10;
|
||||
# switch here
|
||||
use v5.36;
|
||||
# no switch here
|
||||
use feature "switch";
|
||||
# switch here
|
||||
|
||||
Smart match now requires the C<smartmatch> feature, which is enabled
|
||||
by default and included in all feature bundles up to 5.40. It is
|
||||
disabled for the 5.41 feature bundle and later, but can be separately
|
||||
enabled:
|
||||
|
||||
# smartmatch here
|
||||
use v5.41;
|
||||
# no smartmatch here
|
||||
use feature "smartmatch";
|
||||
# smartmatch here

|

=item *
|
||||
|
||||
Subroutines in packages no longer need to be stored in typeglobs:
|
||||
declaring a subroutine will now put a simple sub reference directly in the
|
||||
stash if possible, saving memory. The typeglob still notionally exists,
|
||||
so accessing it will cause the stash entry to be upgraded to a typeglob
|
||||
(i.e. this is just an internal implementation detail).
|
||||
This optimization does not currently apply to XSUBs or exported
|
||||
subroutines, and method calls will undo it, since they cache things in
|
||||
typeglobs.
|
||||
[L<GH #23001|https://github.com/Perl/perl5/issues/23001>]
|
||||
|

(This optimization was originally announced in L<perl5220delta>, but due to a
|
||||
bug it only worked for subroutines in package C<main>, not in modules.)

|

Two new API functions are introduced to convert strings encoded in
|
||||
native bytes format to UTF-8. These return the string unchanged if its
|
||||
UTF-8 representation is the same as the original. Otherwise, new memory
|
||||
is allocated to contain the converted string. This is in contrast to
|
||||
the existing L<perlapi/C<bytes_to_utf8>> which always allocates new
|
||||
memory. The new functions are L<perlapi/C<bytes_to_utf8_free_me>> and
|
||||
L<perlapi/C<bytes_to_utf8_temp_pv>>.
|
||||
L<perlapi/C<bytes_to_utf8_temp_pv>> arranges for the new memory to
|
||||
automatically be freed. With C<bytes_to_utf8_free_me>, you are
|
||||
responsible for freeing any newly allocated memory.
|
||||
|
||||
=item *
|
||||
|
||||
The way that subroutine signatures are parsed by the parser grammar has been
|
||||
changed.
|
||||
|
||||
Previously, when parsing individual signature parameters, the parser would
|
||||
accumulate an C<OP_ARGELEM> optree fragment for each parameter on the parser
|
||||
stack, collecting them in an C<OP_LIST> sequence, before finally building the
|
||||
complete argument handling optree itself, in a large action block defined
|
||||
directly in F<perly.y>.
|
||||
|
||||
In the new approach, all the optree generation is handled by newly-defined
|
||||
functions in F<op.c> which are called by the action blocks in the parser.
|
||||
These do not keep state on the parser stack, but instead in a dedicated memory
|
||||
structure referenced by the main C<PL_parser> structure. This is intended to
|
||||
be largely opaque to other code, and accessed only via the new functions.
|
||||
|
||||
This new arrangement is intended to allow more flexible code generation and
|
||||
additional features to be developed in future.

The C<$SIG{__DIE__}> and C<$SIG{__WARN__}> handlers can no longer be invoked

warnings) are processed directly, ignoring C<%SIG> until the original

Perl 5.41.9 represents approximately 5 weeks of development since Perl
|
||||
5.41.8 and contains approximately 17,000 lines of changes across 380 files
|
||||
from 23 authors.
|
||||
|
||||
Excluding auto-generated files, documentation and release tools, there were
|
||||
approximately 9,700 lines of changes to 300 .pm, .t, .c and .h files.
|
||||
|
||||
Perl continues to flourish into its fourth decade thanks to a vibrant
|
||||
community of users and developers. The following people are known to have
|
||||
contributed the improvements that became Perl 5.41.9:
|
||||
|
||||
Andrew Ruthven, Antanas Vaitkus, Aristotle Pagaltzis, Chris 'BinGOs'
|

The list above is almost certainly incomplete as it is automatically
|
||||
generated from version control history. In particular, it does not include
|
||||
the names of the (very much appreciated) contributors who reported issues to
|
||||
the Perl bug tracker.
|
||||
|
||||
Many of the changes included in this version originated in the CPAN modules
|
||||
included in Perl's core. We're grateful to the entire CPAN community for
|
||||
helping Perl to flourish.

Subroutines in packages no longer need to be stored in typeglobs:
|

declaring a subroutine will now put a simple sub reference directly in the

stash if possible, saving memory. The typeglob still notionally exists,

so accessing it will cause the stash entry to be upgraded to a typeglob
|
||||
(i.e. this is just an internal implementation detail).

subroutines, and method calls will undo it, since they cache things in

typeglobs.

Two new API functions are introduced to convert strings encoded in
|
||||
native bytes format to UTF-8. These return the string unchanged if its
|
||||
UTF-8 representation is the same as the original. Otherwise, new memory
|
||||
is allocated to contain the converted string. This is in contrast to
|
||||
the existing L<perlapi/C<bytes_to_utf8>> which always allocates new
|
||||
memory. The new functions are L<perlapi/C<bytes_to_utf8_free_me>> and
|
||||
L<perlapi/C<bytes_to_utf8_temp_pv>>.
|
||||
L<perlapi/C<bytes_to_utf8_temp_pv>> arranges for the new memory to
|
||||
automatically be freed. With C<bytes_to_utf8_free_me>, you are
|
||||
responsible for freeing any newly allocated memory.

The way that subroutine signatures are parsed by the parser grammar has been
|
||||
changed.
|
||||
|
||||
Previously, when parsing individual signature parameters, the parser would
|
||||
accumulate an C<OP_ARGELEM> optree fragment for each parameter on the parser
|
||||
stack, collecting them in an C<OP_LIST> sequence, before finally building the
|
||||
complete argument handling optree itself, in a large action block defined
|
||||
directly in F<perly.y>.
|
||||
|
||||
In the new approach, all the optree generation is handled by newly-defined
|
||||
functions in F<op.c> which are called by the action blocks in the parser.
|
||||
These do not keep state on the parser stack, but instead in a dedicated memory
|
||||
structure referenced by the main C<PL_parser> structure. This is intended to
|
||||
be largely opaque to other code, and accessed only via the new functions.
|
||||
|
||||
This new arrangement is intended to allow more flexible code generation and
|
||||
additional features to be developed in future.

The list above is almost certainly incomplete as it is automatically
|
||||
generated from version control history. In particular, it does not include
|
||||
the names of the (very much appreciated) contributors who reported issues to
|
||||
the Perl bug tracker.
|
||||
|
||||
Many of the changes included in this version originated in the CPAN modules
|
||||
included in Perl's core. We're grateful to the entire CPAN community for
|
||||
helping Perl to flourish.

||||
|
||||
