Since we have a "preferred" Message-ID in case of conflicts, use it as the UUID in an Atom feed so readers do not get confused by conflicts. --- lib/PublicInbox/Feed.pm | 36 ++++++++-------- lib/PublicInbox/Inbox.pm | 9 ++++ lib/PublicInbox/SearchMsg.pm | 6 +-- lib/PublicInbox/SearchView.pm | 14 +++--- lib/PublicInbox/View.pm | 93 ++++++++++++++++++---------------------- lib/PublicInbox/WWW.pm | 1 + lib/PublicInbox/WwwAtomStream.pm | 9 ++-- t/psgi_v2.t | 26 +++++++++++ 8 files changed, 109 insertions(+), 85 deletions(-) diff --git a/lib/PublicInbox/Feed.pm b/lib/PublicInbox/Feed.pm index 74d0bbd..f2285a6 100644 --- a/lib/PublicInbox/Feed.pm +++ b/lib/PublicInbox/Feed.pm @@ -8,18 +8,18 @@ use warnings; use PublicInbox::MIME; use PublicInbox::View; use PublicInbox::WwwAtomStream; +use PublicInbox::SearchMsg; # this loads w/o Search::Xapian # main function sub generate { my ($ctx) = @_; - my $oids = recent_blobs($ctx); - return _no_thread() unless @$oids; + my $msgs = recent_msgs($ctx); + return _no_thread() unless @$msgs; - my $git = $ctx->{-inbox}->git; + my $ibx = $ctx->{-inbox}; PublicInbox::WwwAtomStream->response($ctx, 200, sub { - while (my $oid = shift @$oids) { - my $msg = $git->cat_file($oid) or next; - return PublicInbox::MIME->new($msg); + while (my $smsg = shift @$msgs) { + $ibx->smsg_mime($smsg) and return $smsg; } }); } @@ -36,9 +36,8 @@ sub generate_thread_atom { $ctx->{-html_url} = $html_url; my $msgs = $res->{msgs}; PublicInbox::WwwAtomStream->response($ctx, 200, sub { - while (my $msg = shift @$msgs) { - $msg = $ibx->msg_by_smsg($msg) and - return PublicInbox::MIME->new($msg); + while (my $smsg = shift @$msgs) { + $ibx->smsg_mime($smsg) and return $smsg; } }); } @@ -62,20 +61,19 @@ sub generate_html_index { sub new_html { my ($ctx) = @_; - my $oids = recent_blobs($ctx); - if (!@$oids) { + my $msgs = recent_msgs($ctx); + if (!@$msgs) { return [404, ['Content-Type', 'text/plain'], ["No messages, yet\n"] ]; } $ctx->{-html_tip} = '
