The InboxIdler still uses ->each_inbox which will struggle with 100K inboxes. Having messages in the top-level newsgroup name of an inbox will still waste bandwidth for clients which want to do full syncs once there's a rollover to a new 50K range. So instead, make every inbox accessible exclusively via 50K slices in the form of "$NEWSGROUP.$UID_MIN-$UID_END". This introduces the DummyInbox, which makes $NEWSGROUP and every parent component a selectable, empty inbox. This aids navigation with mutt and possibly other MUAs. Finally, the xt/perf-imap-list maintainer test is broken, now, so remove it. The grep perlfunc is already proven effective, and we'll have separate tests for mocking out ~100k inboxes. --- MANIFEST | 2 +- lib/PublicInbox/Config.pm | 7 ++- lib/PublicInbox/DummyInbox.pm | 21 +++++++++ lib/PublicInbox/IMAP.pm | 64 +++++++++---------------- lib/PublicInbox/IMAPD.pm | 88 ++++++++++++++++------------------- t/imap.t | 33 +++++++++++-- t/imapd.t | 22 +++++---- xt/imapd-mbsync-oimap.t | 5 +- xt/imapd-validate.t | 9 ++-- xt/perf-imap-list.t | 38 --------------- 10 files changed, 139 insertions(+), 150 deletions(-) create mode 100644 lib/PublicInbox/DummyInbox.pm delete mode 100644 xt/perf-imap-list.t diff --git a/MANIFEST b/MANIFEST index 957228250a7..a133b71f881 100644 --- a/MANIFEST +++ b/MANIFEST @@ -105,6 +105,7 @@ lib/PublicInbox/DS.pm lib/PublicInbox/DSKQXS.pm lib/PublicInbox/DSPoll.pm lib/PublicInbox/Daemon.pm +lib/PublicInbox/DummyInbox.pm lib/PublicInbox/Emergency.pm lib/PublicInbox/Eml.pm lib/PublicInbox/EmlContentFoo.pm @@ -357,7 +358,6 @@ xt/imapd-validate.t xt/mem-msgview.t xt/msgtime_cmp.t xt/nntpd-validate.t -xt/perf-imap-list.t xt/perf-msgview.t xt/perf-nntpd.t xt/perf-threading.t diff --git a/lib/PublicInbox/Config.pm b/lib/PublicInbox/Config.pm index c18c9c75b4f..19535beb973 100644 --- a/lib/PublicInbox/Config.pm +++ b/lib/PublicInbox/Config.pm @@ -105,13 +105,16 @@ sub iterate_start { $self->{-iter} = [ \$i, $cb, $arg ]; } -# for PublicInbox::DS::next_tick +# for PublicInbox::DS::next_tick, we only call this is if +# PublicInbox::DS is already loaded sub event_step { my ($self) = @_; my ($i, $cb, $arg) = @{$self->{-iter}}; my $section = $self->{-section_order}->[$$i++]; delete($self->{-iter}) unless defined($section); - $cb->($self, $section, $arg); + eval { $cb->($self, $section, $arg) }; + warn "E: $@ in ${self}::event_step" if $@; + PublicInbox::DS::requeue($self) if defined($section); } sub lookup_newsgroup { diff --git a/lib/PublicInbox/DummyInbox.pm b/lib/PublicInbox/DummyInbox.pm new file mode 100644 index 00000000000..e38f9e5a432 --- /dev/null +++ b/lib/PublicInbox/DummyInbox.pm @@ -0,0 +1,21 @@ +# Copyright (C) 2020 all contributors +# License: AGPL-3.0+ +# +# An EXAMINE-able, PublicInbox::Inbox-like object for IMAP.
