Subject: [PATCH 00/11] ds: more updates
Date: Sat, 29 Jun 2019 19:59:40 +0000
Message-ID: <20190629195951.32160-1-e@80x24.org> (raw)

We can simplify a lot of our async logic now that we don't have
to deal with the buffer-to-heap behavior of Danga::Socket.

The biggest change is now we no longer tie git-http-backend(1)
runtime and memory use to the bandwidth of a slow HTTP client.
This increases buffering on the FS (which may be tmpfs or
a fast SSD); but it's what nginx (and varnish) would be doing,
anyways

We can further remove a lot of the EvCleanup code since that
was to workaround deferred close being deferred for too long
when no I/O events were firing.

HTTPS now works, but more work needs to be done because
Varnish is still a requirement for busy sites.

Eric Wong (11):
  ds: share lazy rbuf handling between HTTP and NNTP
  ds: move requeue logic over from NNTP
  http: use requeue instead of watch_in1
  listener: use edge-triggered notifications
  ds: handle deferred DS->close after timers
  ds: consolidate IO::Socket::SSL checks
  http: support HTTPS (kinda)
  parentpipe: document and use one-shot wakeups
  parentpipe: make the ->close call more obvious
  httpd/async: switch to buffering-as-fast-as-possible
  http: use bigger, but shorter-lived buffers for pipes
