NAME

App::karr::SyncGuard - Push guard with automatic retry on scope exit

VERSION

version 0.205

SYNOPSIS

my $guard = $self->sync_before;  # git pull + return guard
# ... command logic ...
$self->sync_after;               # explicit push
$guard->done;                    # mark guard as done (DESTROY no-ops)
undef $guard;

# If die/croak happens before sync_after:
# Guard DESTROY runs sync_after with 3 retries, then dies with clear error

DESCRIPTION

App::karr::SyncGuard is created by "sync_before" in App::karr::Role::SyncLifecycle. It acts as an insurance policy: if the command body dies or croaks before "sync_after" in App::karr::Role::SyncLifecycle is called explicitly, the guard's DESTROY runs sync_after with retry logic, ensuring refs are pushed even on failure.

METHODS

done

$guard->done;

Marks the guard as successfully completed. After this is called, the guard's DESTROY is a no-op. Call this after "sync_after" succeeds.

errs

my @errors = $guard->errs;

Returns the list of error messages from retry attempts.
