By default, variables are private to each thread, and each newly created
-thread gets a private copy of each existing variable. This module allows
-you to share variables across different threads (and pseudoforks on Win32).
-It is used together with the threads module.

=head1 FUNCTIONS
=item share VARIABLE
-C<share> takes a value and marks it as shared. You can share a scalar,
-array, hash, scalar ref, array ref or hash ref. C<share> will return
-the shared rvalue but always as a reference.
-
-C<share> will traverse up references exactly I<one> level.
-C<share(\$a)> is equivalent to C<share($a)>, while C<share(\\$a)> is not.
-This means that you must create nested shared data structures by first
-creating individual shared leaf notes, then adding them to a shared hash
-or array.
+C<share> takes a value and marks it as shared. You can share a scalar, array,
+hash, scalar ref, array ref, or hash ref. C<share> will return the shared
+rvalue, but always as a reference.
A variable can also be marked as shared at compile time by using the
-C<shared> attribute: C<my $var : shared>.
+C<:shared> attribute: C<my $var :shared;>.
-If you want to share a newly created reference unfortunately you
-need to use C<&share([])> and C<&share({})> syntax due to problems
-with Perl's prototyping.
+Due to problems with Perl's prototyping, if you want to share a newly created
+reference, you need to use the C<&share([])> and C<&share({})> syntax.
The only values that can be assigned to a shared scalar are other scalar
-values, or shared refs, eg
+values, or shared refs:
+
+ my $var :shared;
+ $var = 1; # ok
+ $var = []; # error
+ $var = &share([]); # ok
+
+C<share> will traverse up references exactly I<one> level. C<share(\$a)> is
+equivalent to C<share($a)>, while C<share(\\$a)> is not. This means that you
+must create nested shared data structures by first creating individual shared
+leaf nodes, and then adding them to a shared hash or array.
- my $var : shared;
- $var = 1; # ok
- $var = &share([]); # ok
- $var = []; # error
- $var = A->new; # error
- $var = &share(A->new); # ok as long as the A object is not nested
+ my %hash :shared;
+ $hash{'meaning'} = &share([]);
+ $hash{'meaning'}[0] = &share({});
+ $hash{'meaning'}[0]{'life'} = 42;
-Note that it is often not wise to share an object unless the class itself
-has been written to support sharing; for example, an object's destructor
-may get called multiple times, one for each thread's scope exit.
+=item is_shared VARIABLE
+
+C<is_shared> checks if the specified variable is shared or not. If shared,
+returns the variable's internal ID (similar to
+L<refaddr()|Scalar::Util/"refaddr EXPR">). Otherwise, returns C<undef>.
+
+ if (is_shared($var)) {
+ print("\$var is shared\n");
+ } else {
+ print("\$var is not shared\n");
+ }
=item lock VARIABLE
-C<lock> places a lock on a variable until the lock goes out of scope.
-If the variable is locked by another thread, the C<lock> call will
-block until it's available. C<lock> is recursive, so multiple calls
-to C<lock> are safe -- the variable will remain locked until the
-outermost lock on the variable goes out of scope.

+available. C<lock> is recursive, so multiple calls to C<lock> are safe -- the
+variable will remain locked until the outermost lock on the variable goes out
+of scope.
+
+If a container object, such as a hash or array, is locked, all the elements of
+that container are not locked. For example, if a thread does a C<lock @a>,
+any other thread doing a C<lock($a[12])> won't block.

=item cond_wait VARIABLE
=item cond_wait CONDVAR, LOCKVAR
-The C<cond_wait> function takes a B<locked> variable as a parameter,
-unlocks the variable, and blocks until another thread does a
-C<cond_signal> or C<cond_broadcast> for that same locked variable.
-The variable that C<cond_wait> blocked on is relocked after the
-C<cond_wait> is satisfied. If there are multiple threads
-C<cond_wait>ing on the same variable, all but one will reblock waiting
-to reacquire the lock on the variable. (So if you're only using
-C<cond_wait> for synchronisation, give up the lock as soon as
-possible). The two actions of unlocking the variable and entering the
-blocked wait state are atomic, the two actions of exiting from the
-blocked wait state and relocking the variable are not.
-
-In its second form, C<cond_wait> takes a shared, B<unlocked> variable
-followed by a shared, B<locked> variable. The second variable is
-unlocked and thread execution suspended until another thread signals
-the first variable.
-
-It is important to note that the variable can be notified even if
-no thread C<cond_signal> or C<cond_broadcast> on the variable.
-It is therefore important to check the value of the variable and
-go back to waiting if the requirement is not fulfilled. For example,
-to pause until a shared counter drops to zero:
-
- { lock($counter); cond_wait($count) until $counter == 0; }

=item cond_timedwait VARIABLE, ABS_TIMEOUT
=item cond_timedwait CONDVAR, ABS_TIMEOUT, LOCKVAR
-In its two-argument form, C<cond_timedwait> takes a B<locked> variable
-and an absolute timeout as parameters, unlocks the variable, and blocks
-until the timeout is reached or another thread signals the variable. A
-false value is returned if the timeout is reached, and a true value
-otherwise. In either case, the variable is re-locked upon return.

=item cond_signal VARIABLE
-The C<cond_signal> function takes a B<locked> variable as a parameter
-and unblocks one thread that's C<cond_wait>ing on that variable. If
-more than one thread is blocked in a C<cond_wait> on that variable,
-only one (and which one is indeterminate) will be unblocked.

+unblocks one thread that's C<cond_wait>ing on that variable. If more than one
+thread is blocked in a C<cond_wait> on that variable, only one (and which one
+is indeterminate) will be unblocked.
-If there are no threads blocked in a C<cond_wait> on the variable,
-the signal is discarded. By always locking before signaling, you can
-(with care), avoid signaling before another thread has entered cond_wait().

=item cond_broadcast VARIABLE
The C<cond_broadcast> function works similarly to C<cond_signal>.
-C<cond_broadcast>, though, will unblock B<all> the threads that are
-blocked in a C<cond_wait> on the locked variable, rather than only one.

-=head1 BUGS
+=head1 BUGS AND LIMITATIONS
-C<bless> is not supported on shared references. In the current version,
-C<bless> will only bless the thread local reference and the blessing
-will not propagate to the other threads. This is expected to be
-implemented in a future version of Perl.
+When C<share> is used on arrays, hashes, array refs or hash refs, any data
+they contain will be lost.
-Does not support splice on arrays!
+ my @arr = qw(foo bar baz);
+ share(@arr);
+ # @arr is now empty (i.e., == ());
-Taking references to the elements of shared arrays and hashes does not
-autovivify the elements, and neither does slicing a shared array/hash
-over non-existent indices/keys autovivify the elements.
+ # Create a 'foo' object
+ my $foo = { 'data' => 99 };
+ bless($foo, 'foo');
-share() allows you to C<< share $hashref->{key} >> without giving any error
-message. But the C<< $hashref->{key} >> is B<not> shared, causing the error
-"locking can only be used on shared values" to occur when you attempt to
-C<< lock $hasref->{key} >>.
+ # Share the object
+ share($foo); # Contents are now wiped out
+ print("ERROR: \$foo is empty\n")
+ if (! exists($foo->{'data'}));
-=head1 AUTHOR
+Therefore, populate such variables B<after> declaring them as shared. (Scalar
+and scalar refs are not affected by this problem.)
+
+It is often not wise to share an object unless the class itself has been
+written to support sharing. For example, an object's destructor may get called
+multiple times, one for each thread's scope exit. Another example, is that
+the contents of hash-based objects will be lost due to the above mentioned
+limitation.
