Batches

[bbkr]

Spec

Exceptions won't be thrown on error, instead of that exception objects will be returned in result array.

This has to be implemented along with notifications, because notifications should be skipped in response batch while maintaining requests order.

Interface suggestion:

$client.rpc.batch.method_name("param");
$client.rpc.batch.rpc.notification.method_name("param"); # notification in batch
$client.rpc.batch.method_name("param");
my @results = $client.rpc.flush;

Batches already works on Server side, commit 96504cc

On Client side syntax will be:

my $b = $client."rpc.batch"(); # get handle with batch context
$b.foo() # stack foo method call
$b.bar() # stack bar method call
my $result = $client."rpc.flush"();

Explanation:

According to spec method names that begin with "rpc." are reserved for internal processing. Quoted method "rpc.batch" must be used to avoid confusing with dispatch to "rpc" method, which is not internal.

Notifications in batches:

$b will be treated just the same as $client, so Notification can derive its own handle with notification handle from it

$b."rpc.notification"().foo() # stack foo notification in batch

Reversing batch and notification context may also be allowed:

my $n = $client."rpc.notification"();
my $b = $n."rpc.batch"();
$b.foo(); $b.bar() ... # all methods stacked in batch will be notifications

Implemented!
