On April 10-11th 2014, we'll hold an official ATS Summit in Denver, CO. All developers and community participants are welcome to join. If you plan on attending, please add to the list below. For session chairs and co-chairs, please update the section below with session details, and be prepared to lead the discussions at the summit. Slides are not required, but would not hurt.
- When and Where
When and Where
The summit will take place in Denver, CO, April 10-11 2014. Location: The Westin Denver Downtown, same as the ApacheCon 2014 conference.
The schedule is to be finalized, but here's a brief overview.
Morning sessions (9-12)
Afternoon sessions (1-6pm)
Fogo de Chao*
Session 1 / 2
Session 5 & Closure
*Wednesday night dinner is going to be sponsored by LinkedIn at Fogo de Chao.
**We have a reserved room at Wynkoop Brewing on Thursday night for 20. That is the maximum capacity of that room. Right now we have 20 RSVP's for that night. If we end up over flowing we will figure something out. Perhaps a small group can go get a separate table in the main dining area, but our experience is that fewer people show up than RSVP so we should be OK. Also, I wanted to note that it will be 21 and over only. I don't think we have anyone under 21 though, so that should be OK (If that is not the case let me know ASAP!). Also, we currently have no sponsorship for this dinner.
- Hangout: https://plus.google.com/hangouts/_/76cpio91gfntctfd06dqgf8r1o
- Notes are being kept at Session Notes
TBD, here are a few ideas, see for https://cwiki.apache.org/confluence/display/TS/4.x+Project+plan details on some of these ideas. I'm looking for a session leader for each of the project ideas, that will help drive each session. Everyone who is interested in any of these sessions should also prepare as much as they can: Read up on the issues, research, and scope requirements from your perspective.
Each session should nominate a note-taker, who will take notes to be published in the wiki and on the mailing list.
Please mark all JIRA tickets with the Label: SUMMIT-APR2014 that should be addressed during one of the following sessions.
Session 1: Intros, Followup from previous Summit, and other minor topics
Session chairs: Leif & Bryan C.
This session will introduce this summit, as well as report and discuss on actionable items from previous summit. This includes:
- Introductions and agenda bashing
- Lua configurations
- Cache improvements
- C++ API, plugin APIs
- DNS, HostDB and Load Balancing
- SSL Hooks for context manipulation
We'll also do some minor discussions here, which do not fit into a full session. This includes:
- Summit Agendas: Revisit frequency and locations
- Release process: Is it better? Do we need to fine tune, or revisit ?
Session 2: Lua configurations, part deux
Session chairs: Daniel and Theo
We have the basics of our new Lua configuration in place (in a branch), and this discussion is to iterate over what we've done, and where to go. In particular, we will
- Current status
- What works, what doesn't?
- When to freeze APIs (6.0 ?)
Session 3: Plugins and Plugin APIs
Session chairs: Brian Geffon and Bryan Call
With the upcoming v5.0.0 release, this is a golden opportunity to go through our APIs, and improve and fix things that are less than perfect. Some examples are
- Parameter types for "length" values. Current we tend to use "int", in some places we use size_t, and we should make this consistent.
- "bool" type (in C99) vs "int" ?
- Deprecate APIs
- Add frequently used "patterns" as core APIs? One things comes to mind, SetHeader() which is a "remove" followed by an "add", and is commonly performed.
- Mgmt APIs, what do we need to do here to make this usable?
- C++ APIs: Status and future
- Remap config: make remap level @ params available to plugins.
We should also discuss about what plugins should be stable for v5.0.0, future plugins development etc.
Session 4: Reload, seamless restart and upgrades
Session chairs: Jan van Doorn & Phil Sorber
- All (most?) configuration should be reload-able
- What is impossible to reload? Output a warning that config X has not been changed.
- Can we restart in place (for binary upgrades) without breaking existing transfers (disconnect after the current request)?
- Status of reload without parsing logs after the fact (synchronous/blocking output from traffic_line -x)
- Cache upgrades
Session 5: SPDY 2/3/4 and HTTP/2, WebSockets
Session chairs: Brian Geffon & Uri Shachar
We currently have 2 different SPDY implementations, and the future of SPDY is clearly HTTP/2 (according to Google). How do we integrate this well into ATS. Discussions include
- Plugin vs core
- Client vs Origin connections
- Integration with internals (transforms, caches etc.)
- Extensibility (H3, H4 etc. ?)
As time permits and there is interest, we have the following list of group activities.
- GPG key signing. This is particularly important if you are going to prepare official ASF releases, but everyone is encouraged to get their GPG keys signed. Make sure to bring your key signatures and an appropriate form (or two!) of identifications. See https://we.riseup.net/riseuplabs+paow/openpgp-best-practices for some useful hints on managing your GPG keys (thanks Igor!).
- Trust falls.
