IPC->awaitpid_init now allows pre-registering callbacks before spawning workers. --- lib/PublicInbox/IPC.pm | 30 ++++++++++++++---------------- lib/PublicInbox/LEI.pm | 8 +++----- lib/PublicInbox/LeiConvert.pm | 2 +- lib/PublicInbox/LeiInput.pm | 2 +- lib/PublicInbox/LeiMirror.pm | 7 +++---- lib/PublicInbox/LeiStore.pm | 7 +++---- lib/PublicInbox/LeiToMail.pm | 7 +++---- lib/PublicInbox/LeiUp.pm | 5 ++--- lib/PublicInbox/LeiXSearch.pm | 9 ++++----- script/public-inbox-clone | 2 +- 10 files changed, 35 insertions(+), 44 deletions(-) diff --git a/lib/PublicInbox/IPC.pm b/lib/PublicInbox/IPC.pm index 34e40118..edc5ba64 100644 --- a/lib/PublicInbox/IPC.pm +++ b/lib/PublicInbox/IPC.pm @@ -12,7 +12,7 @@ use strict; use v5.10.1; use parent qw(Exporter); use Carp qw(croak); -use PublicInbox::DS qw(dwaitpid); +use PublicInbox::DS qw(awaitpid); use PublicInbox::Spawn; use PublicInbox::OnDestroy; use PublicInbox::WQWorker; @@ -133,26 +133,26 @@ sub ipc_worker_spawn { $self->{-ipc_req} = $w_req; $self->{-ipc_res} = $r_res; $self->{-ipc_ppid} = $$; + awaitpid($pid, \&ipc_worker_reap, $self); $self->{-ipc_pid} = $pid; } -sub ipc_worker_reap { # dwaitpid callback - my ($args, $pid) = @_; - my ($self, @uargs) = @$args; +sub ipc_worker_reap { # awaitpid callback + my ($pid, $self) = @_; delete $self->{-wq_workers}->{$pid}; - return $self->{-reap_do}->($args, $pid) if $self->{-reap_do}; + if (my $cb_args = $self->{-reap_do}) { + return $cb_args->[0]->($pid, $self, @$cb_args[1..$#$cb_args]); + } return if !$?; my $s = $?
