From 15782f34be59578fbec95c01f057bcf2d133414f Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 20 Aug 2015 02:30:25 +0000 Subject: feed: remove threading from index We'll be making the index smarter for people with search support enabled. Otherwise, it'll be chronological and a bit dumb. At least it'll use less memory. --- lib/PublicInbox/Feed.pm | 72 ++++++++++++++++--------------------------------- 1 file changed, 23 insertions(+), 49 deletions(-) (limited to 'lib') diff --git a/lib/PublicInbox/Feed.pm b/lib/PublicInbox/Feed.pm index 95bde4f5..253eed2a 100644 --- a/lib/PublicInbox/Feed.pm +++ b/lib/PublicInbox/Feed.pm @@ -40,7 +40,7 @@ sub generate { my $git = PublicInbox::GitCatFile->new($ctx->{git_dir}); each_recent_blob($ctx, sub { - my ($add) = @_; + my ($add, undef) = @_; add_to_feed($feed_opts, $feed, $add, $git); }); $git = undef; # destroy pipes @@ -50,7 +50,6 @@ sub generate { sub generate_html_index { my ($class, $ctx) = @_; - require PublicInbox::Thread; my $max = $ctx->{max} || MAX_PER_PAGE; my $feed_opts = get_feedopts($ctx); @@ -58,30 +57,27 @@ sub generate_html_index { my $title = $feed_opts->{description} || ''; $title = PublicInbox::Hval->new_oneline($title)->as_html; - my @messages; - my $git_dir = $ctx->{git_dir}; - my $git = PublicInbox::GitCatFile->new($git_dir); - my ($first, $last) = each_recent_blob($ctx, sub { - mime_load_for_sort($git, $_[0], \@messages); - }); - $git = undef; # destroy pipes. - - my $th = PublicInbox::Thread->new(@messages); - $th->thread; my $html = "$title" .
