Revision history for Perl extension Aspect
0.90 Thu 27 May 2010
- Updating to Module::Install::DSL 0.97
- Upgraded the old method-based match_run run-time context testing
interface to a newer compiled_runtime context testing interface.
The new interface cooks the run-time tests down to a single
compiled perl condition where possible, and a set of nested
function calls where strings cannot be used. The function calls
alone are faster than methods, and the functions have no
parameters, making them faster still. Tests that can be compiled
all the way down to a string are even faster, because they avoid
Perl's expensive function calls, and get even faster because
Perl's opcode optimisations get a much better shot at improving
the generated code.
- Upgraded the weave-time mechanism to work using compiled code in
the same fashion as the run-time code. This should make the weave
costs (the time to scan the entire namespace) much lower as well.
- Expanded out the POD documentation to cover the entire namespace
tree.
0.45 Mon 10 May 2010
- Updating to Module::Install::DSL 0.96
- More performance tuning of the namespace scanner in match_all.
- A wide range of cleanups, improvements and expansions to the
previously existing documentation. This includes full
documentation for the entire Aspect::Pointcut tree.
- Renamed the new API for join point contexts from Aspect::Context
to Aspect::Point.
- Aspect libraries in namespaces other than Aspect::Library:: can
now be used as long as the module inherits from the (empty)
identifying base class Aspect::Library. All libraries that
currently inherit from Aspect::Modular automatically inherit from
the new Aspect::Library as well.
- Started work on third-generation optimiser for Aspect::Pointcut.
This functionality will be hidden until it is complete enough
to use.
0.44 Mon 15 Feb 2010 - Adam Kennedy
- Inlined and reimplemented a stripped down and faster replacement
for the functionality provided by Devel::Symdump to make match_all
significantly faster and remove potential issues with Devel::Symdump
on Mac OS 5.10.0
0.43 Thu 28 Jan 2010 - Adam Kennedy
- Fixed a pointcut optimisation problem where we were currying away
call checking in complex nested pointcuts where runtime pointcuts
needed to retain the call checking to limit the run-time checks
to an appropriate subset of the total number of functions hooked.
- More elements of what will ultimately become the pointcut context
are passed through to the curried pointcut tests (in preparation
for moving to a File::Find::Rule-like string-eval-compiled form
of the pointcut.
0.42 Wed 20 Jan 2010 - Adam Kennedy
- Began the implementation of the new Aspect::Context tree
- Generated advice hook code now cheats for speed and blesses
context objects directly into the advice-specific Aspect::Context
class, which should be safe now the contexts have a dumb
constructor.
- Pointcut matching now correctly ignores exported Aspect functions.
- Added in initial stub for Aspect::Library (the renaming of
Aspect::Modular).
- Moved Aspect::Advice::Hook to Aspect::Hook to provide Advice/Hook
class symmetry, and make it no longer an Advice subclass.
- Removed temporary debugging code in Aspect::Library::Breakpoint
that slipped through into production
0.41 Wed 20 Jan 2010 - Adam Kennedy
- So few pointcuts care about the sub name at run-time that
it doesn't make sense to pass it as a separate parameter
to match_run. Include it in the run-time HASH instead.
- Normalise changes to return_value inside the advice code,
rather than after it by using the ->{wantarray} context attribute
to know when that normalisation is needed. This allows us to cheat
in the hook code and use ->{return_value} directly, which is
significantly faster than calling ->return_value.
0.40 Tue 19 Jan 2010 - Adam Kennedy
- Added experimental Aspect::Library::Throwing pointcut
- Only nested pointcuts containing only call() would curry away.
Now nested mixed pointcuts curry out as well.
- Nested And|Or pointcuts curry to faster flat 3+ element And|Or
0.39 Tue 19 Jan 2010 - Adam Kennedy
- All hook code is now generated in a single namespace
- Added the Aspect::Library::Wantarray pointcut
0.38 Tue 19 Jan 2010 - Adam Kennedy
- Added experimental support for the "highest" pointcut.
- Added experimental support for the Breakpoint reusable library.
0.37 Wed 13 Jan 2010 - Adam Kennedy
- Added support for "Aspect ':legacy'", which will cause the Aspect
module to export functions with their original behaviours.
Only the original aspect/before/after/call/cflow functions are
exported and after() advice applies the same behaviour as the
equivalent new-API advice function after_returning().
- To prevent hassles with Exporter (and since we need Sub::Install
anyway to implement :legacy) replace all uses of Exporter with
a trivial hand-rolled equivalent using Sub::Install.
- Added the Aspect::Pointcut::If pointcut to match Java's equivalent
if PointCut primitive. Unfortunately, since it's going to be a bit
to hard to actually use "if" in a function, we will use "if_true"
instead.
- Added Sub::Uplevel to the list of untouchables to prevent infinite
circular loops.
0.36 Wed 13 Jan 2010 - Adam Kennedy
- WARNING: THIS RELEASE CONTAINS API CHANGES.
To retain compatibility with previous releases, you should change
all of your after() calls to after_returning() calls.
- The after () advice now traps BOTH orginary return values and
exceptions, as per the AspectJ implementation.
- To provide a more consistent naming of pointcuts (in preparation
for adding more of them) renamed the logical pointcut classes
to remove the "Op" part of the class name.
- Bumped Test::Exception dependency to 0.29, since it has some
Sub::Uplevel fixes, and we use that heavily.
0.35 Mon 11 Jan 2010 - Adam Kennedy
- Adding initial support for exceptions, with after_throwing
0.34 Sun 10 Jan 2010 - Adam Kennedy
- Adding Aspect::Advice::AfterReturning before we implement exception
support in the main ::After advice.
0.33 Fri 8 Jan 2010 - Adam Kennedy
- Added Test::NoWarnings to all of the tests
- Refactoring advice testing into one test per advice type
- Testing now covers more combinations of cases, including for around()
- Fixed bug in return values for listwise before () calls
- Calls to run_original for advice called in void context now
correctly runs the underlying hooked method in void context as well.
- When called in after() or around() advice, proceed will throw an
exception.
- Removed some of the author tests I don't care about as much.
0.32 Thu 7 Jan 2010 - Adam Kennedy
- The actual term "forever" is meaningless. Reversed the flag to
be used as "lexical" instead.
0.31 Thu 7 Jan 2010 - Adam Kennedy
- Removed the loading of Aspect::Library::Memoize and
Aspect::Library::TestClass in 01_compile.t which was causing
installation failure.
0.30 Thu 7 Jan 2010 - Adam Kennedy
- Extended the forever currying support to the overall Aspect itself,
and upgraded the regular Library classes to implement it properly.
- Renamed the term "forever" to a more simple "global" name.
- Moved Aspect::Library::Memoize into a seperate distribution to
remove the Memoize dependency, which isn't 100% reliable.
0.29 Wed 6 Jan 2010 - Adam Kennedy
- Added "forever currying" support. If advice is created in
void context we never add the $out_of_scope hook, and as a
result we don't need to save the advice object at all (and just
let it immediately destroy). As well as removing the need for a
bunch of the nasty curried objects, we remove an unnecesary if ()
test for every single call (to non-lexical hooks).
0.28 Wed 6 Jan 2010 - Adam Kennedy
- Implemented Pointcut currying. The pointcut objects will
optimise themselves down to just the section that should run
if we assume the function was hooked correctly.
This not only makes the hooks much more efficient in working
out if they need to fire, but it also fixes a major bug with
negative call pointcuts always causing all functions to not fire.
- Resolved RT #36527 - Minor doc bug s/Profiled/Profiler/
- Moved Aspect::Library::Listenable into it's own distribution
- Migrated all the tests from Test::Class to normal Test::More
- Various code clean up and simplification, with less exporting
- Added missing Task::Weaken dependency
- Fixed, hopefully, the "variables will not remain shared" but
by moving from using pure named hook functions to assigning
anonymous subroutines to the typeglob instead.
- Pointcuts now boolify (quickly) to true, and don't stringify to
a Data::Dumper debugging spew any more.
- Implemted the internals needed to support AndOp and OrOp pointcuts
with more than 2 elements, so that in future long chained
collections of & or | pointcuts will collapse down into a single
object, instead of building as giant nested trees of boolean pairs.
0.27 Sun 3 Jan 2010 - Adam Kennedy
- Various micro-optimisation of Aspect::AdviceContext which would
normally be somewhat pointless, but is useful in this case when
an Aspect hook is applied to something which is in the hot loop
for some program.
- Added a test script to specifically hunt down the problems with
variable sharing in string-eval'ed closures.
0.26 Thu 31 Dec 2009 - Adam Kennedy
- With the primary internals refactoring completely, we now start
a series of commits to remove excessive abstractions, and to alter
others to more appropriate abstractions (still without changing
any of the APIs)
- Cleaning up and refactoring the Aspect/Advice constructor code in
Aspect.pm
- Removed the weird Aspect::Advice->new( type, code, pointcut ) for
a more conventional ->new setup.
- Attempt to load Sub::Uplevel earlier (before we load Exporter) so
there is an increased likelyhood that we don't have to reload
Exporter later.
- Removed redundant references to Hook::LexWrap from the POD, and
removed the "Convert to Sub::Uplevel" item from the TO DO list.
- Rewrote the Pointcut family of classes to have a simpler structure
which should be faster. Some now use blessed ARRAYs as a
preparatory step for allowing the AndOp/OrOp pointcuts to have
more than just two elements (and to allow enable certain
optimisation strategies down the line).
- Removed the faulty Aspect::Pointcut::BinOp abstraction entirely.
It was causing boolean and/or operations to always run both sides,
so unlike the overloaded expression they were created from, they
would never shortcut. This is now resolved, and the an/or pointcut
elements now shortcut properly.
0.25 Thu 31 Dec 2009 - Adam Kennedy
- Debundled various out-of-date testing libraries, and reverted
to more conventional build_requires dependencies now that our
downstream packaging systems have the ability to consume them.
- Since the code documents the Aspect::Advice->install method as
private (and it is undocumented) rename to ->_install as a
precursor to changing it's behaviour at an API level.
- Now that the descope execution of the closure hook is able to be
trusted, we no longer need the Aspect::Cleanup DESTROY-time
self-execution magick.
- Added the ->wantarray property to the AdviceContext object.
This is provided as a convenience to the user (since the wantarray)
function works properly inside the advice code. It's main use is
for some AspectContext internals.
- Added wantarray context test, which uncovered a bug where
void-context calls were incorrectly running the advice in scalar
context.
0.24 Wed 30 Dec 2009 - Adam Kennedy
- Changes file now uses tabs (to make it less annoying for me) :)
- Moved the inline Aspect::Hook::LexWrap::Cleanup class into it's
own dedicated Aspect::Cleanup class.
- Merged Advice-specific hooks from Aspect::Hook::Lexwrap into the
advice classes.
- Removed the now-redundant Aspect::Hook::Lexwrap entirely
- Simplified the Aspect::AdviceContext constructor to make it faster
- Logically merged the code-generated functionality from ->install
and the Hook::LexWrap-inspired ->hook methods for each Advice
class. This removes a lot of guess work and double handling from
the main execution path, and should be significantly faster.
- With the code merged, pushed the scope exit flag outside the
symbol table iteration in the installer. Instead of a large array
of separate exit-tracking objects, we can instead use one single
shared lexical hook that works via mixed depth closure Magick.
- Only call wantarray once per hook execution and share the result
therafter as a variable. Saves two function calls per hook.
0.23 Thu 24 Dec 2009 - Adam Kennedy
- Removed the concept of a standalone Aspect::Weaver class
- Each Aspect::Advice:: subclass now does most of the setup for the weaving
individually, with similar but slightly different implementations.
This adds some duplication of code, but removes a lot of architectural
complexity. It should make the creation of new types of Advice simpler.
- Corrected the versions of the test libs (which went out of sync)
- The Hook::LexWrap wrap function is now split into Advice-specific hooks
before and after, duplicating some code but making each type simpler and
faster.
0.22 Mon 21 Dec 2009 - Adam Kennedy
- Part one of an upcoming series of major upgrades
- Migrating to Sub::Uplevel to remove our custom CORE::GLOBAL::caller
0.21 Tue 21 Jul 2009 - Adam Kennedy
- Bumped the version to 0.21 so the Hook::LexWrap module indexes
0.16 Tue 19 May 2009 - Adam Kennedy

0.07 Wed, 31 Jul 2002 22:42:27 +0200 (Marcel Gruenauer <marcel@cpan.org>)
- The distribution has been adapted for use with perl5.8.0.
C<Hook::LexWrap> is now a core module, but there was a problem with
context (wantarray) handling with Aspect::Memoize. Sorry about the perl
5.6.x users, but this is bleeding-edge stuff, so you're expected to use
the very latest gear. Anyway, you can still get an earlier version (up
to 0.07) from CPAN, which will work with perl 5.6.x.
- Aspect::Memoize is now intended for subroutines returning scalars only.
That is, if the sub is called in list context, it will still only
memoize, and return, a memoized scalar. Void context obviously doesn't
matter when it comes to memoization; subroutines returning lists are
something I have to think about.
- Tests now use Test::More
0.07 Fri, 15 Mar 2002 09:04:51 +0100 (Marcel Gruenauer <marcel@cpan.org>)
- symbols exported from Aspect.pm now don't generate join points. So I
added Aspect::import() and modified Aspect::JoinPoint::enum() to check
for %Aspect::exp_syms.
0.06 Fri, 26 Oct 2001 16:42:51 +0200 (Marcel Gruenauer <marcel@cpan.org>)

- added Aspect::Attribute interface to creating advice
- made Aspect::Advice's enable() and disable() return $self
- added cookbook example program callflow_attr.pl
- added cookbook recipes for bounds checking and change tracking, plus
sample programs
0.05 Thu, 11 Oct 2001 09:44:50 +0200 (Marcel Gruenauer <marcel@cpan.org>)
- removed dependency on Data::Denter
0.04 Mon, 01 Oct 2001 18:33:00 +0200 (Marcel Gruenauer <marcel@cpan.org>)
