-Implementable right now (but not necessarily important), with caveats
-(unavailable components that will limit what can be implemented right
-away), in order in which they will likely be done:

-0.9.0pre0:
-* TRANSPORT:
- - implement transport API to pretty-print transport address
- + asynchronous transport lookup and non-CPS iterator in peerinfo require
- some work to ensure printing in the proper order...
-* CORE:
- - SET_KEY is triggered every 2.5 minutes (after session is up); should
- just do PING (not SET_KEY + PING)
- - "Forcing disconnect of XXX due to inactivity" -- can happen every few MS!?
- (disconnect does not really succeed, or what?)
- Also, core does not seem to actually decrement the number of active
- sessions even if no connections exist for a while! (likely related...)
- - transport reports bw quota violations on big-endian systems (core or
- transport issue?)
-* HELLO:
- - need function to test "equivalency" of HELLOs; use in topology!
-* FS:
- - GAP improvements:
- + active reply route caching design & implementation of service,
- gap extension!
- - gnunet-publish cannot be aborted using CTRL-C
- - on some systems, keyword search does not find locally published content
- (need testcase of command-line tools!)
- - 2-peer download is still too slow (why?)
- - advanced FS API parts
- + namespaces: fundamental namespace API
- + search: SBlocks, KSBlocks, probes, notify FS-service of known results
- + collection
- + location URIs (publish, search, download)

0.9.0pre1:
-* Module features to implement:
- - tbench (RC-pre1)
- + good to have for DV evaluation!
- - DV (RC-pre1)
- + write DV API
- + implement DV service [Nate & CG]
- + implement DV library [Nate]
- + implement DV transport plugin [Nate & CG]
- + implement testcases [Nate]
- + implement performance tests [Nate]
-* SETUP:
- - design & implement new setup tool
-* GUIs to implement:
- - gtk (RC-pre1)
- + how to integrate scheduler with GTK event loop!
-* HOSTLIST:
- - 'server' uses 'GNUNET_PEERINFO_iterate', should probably switch to notification API
- (for more instant / up-to-date hostlists at lower cost) [OPTIMIZATION]
-* STATISTICS:
- - does not seem to work with timeouts (especially if service is not running)
-* UTIL:
+* PEERINFO: [CG]
- trust: need *fast* way to check/update trust in peers
- (async peerinfo would not be right)
- - scheduler should change OS process priority based on task priority;
- should make better use of task priorities in general
- - only connect() sockets that are ready (select()) [Nils]
- [On W32, we need to select after calling socket before
- doing connect etc.]
-* DATACACHE:
- - add stats (# bytes available, # bytes used, # PUTs, # GETs, # GETs satisfied)
-* FS:
+ (async peerinfo would not be right; certainly not with the current API)
+* TRANSPORT: [CG]
+ - need to implement and test new blacklisting code (server-side only, client API exists)
+* TOPOLOGY: [CG]
+ - needs more testing (especially F2F topology) -- need transport blacklisting to be implemented first!
+* FS: [CG]
+ - support recursive download even if filename is NULL and we hence
+ do not generate files on disk (use temp_filename)
+ - bound parallelism (# fs downloads)
+ - distinguish in performance tracking and event signalling between
+ downloads that are actually running and those that are merely in the queue
- persistence support (publish, unindex, search, download)
- - non-anonymous FS service (needs DHT)
- + basic DHT integration
- + CS-DHT-functions (DHT-put of LOC)
- + P2P-functions (DHT-get)
- - active migration support (in fs or in datastore?)
-* TOPOLOGY:
- - needs more testing (especially F2F topology)
- - needs to re-try connecting after disconnect (currently, it
- initially triggers a connection request, but if that connection
- fails / goes down, it does not retry in a timely fashion;
- cause seems to be the 'blacklist_after_attempt' being set to 1h,
- which is rather long -- and should probably be adjusted based on
- the number of connections / known peers)
- - If the topology daemon crashes, peers that were put on the
- blacklist with transport will never be removed from it (until
- transport service dies); we should use the blacklist notification
- API to learn about the exact set of blacklisted peers at all times
- (FIXME: the transport_api implementation of blacklisting
- also does not work nicely for this since it won't let us know about
- disconnect-reconnect events and the implicit whitelisting
- that might happen here; that's not so bad since we will
- re-blacklist on pre-connect attempts anyway, so this is
- a minor issue).
- - the code uses the term 'blacklist' for both peers that are forbidden
- to connect (i.e. F2F mode) as well as peers that we currently
- won't try to actively connect to ourselves (since we just tried);
- This is confusing. We need two distinct terms.
- - move code to use hash table instead of linked list
- - instead of periodically discarding blacklisted entries,
- simply add task that is triggered at the right time (earlier free,
- more balanced load)
- - check if new HELLO learned is different from old HELLO
- before resetting entire state!
+ - active migration support (in fs or in datastore or new daemon?)
+ - gnunet-service-fs (hot-path routing, load-based routing, nitpicks)
+ - [gnunet-service-fs.c:208]: member 'LocalGetContext::results_bf_size' is never used
+ - [gnunet-service-fs.c:501]: member 'PendingRequest::used_pids_size' is never used
+ - [gnunet-service-fs.c:654]: member 'ConnectedPeer::last_client_replies' is never used
+ - [gnunet-service-fs.c:669]: member 'ConnectedPeer::avg_delay' is never used
+ - [gnunet-service-fs.c:675]: member 'ConnectedPeer::avg_priority' is never used
+ - [gnunet-service-fs.c:688]: member 'ConnectedPeer::pending_requests' is never used
+ - [gnunet-service-fs.c:694]: member 'ConnectedPeer::last_p2p_replies_woff' is never used
+ - [gnunet-service-fs.c:700]: member 'ConnectedPeer::last_client_replies_woff' is never used
+ - GAP improvements:
+ + active reply route caching design & implementation of service; gap extension!
+* TBENCH: [MW]
+ - good to have for transport/DV evaluation!
+* DV: [Nate]
+ - write DV API (need to move declarations from dv_api.c to gnunet_dv_service.h!)
+ - implement DV service
+ - implement DV library (looks done)
+ - implement DV transport plugin
+ - implement testcases
+ - implement performance tests
+* UTIL:
+ - only connect() sockets that are ready (select()) [Nils]
+ [On W32, we need to select after calling socket before doing connect etc.]
+* GNUNET-GTK:
+ - use g_main_context_set_poll_func to integrate GTK with GNUnet Scheduler!? (YUCK!)
+ - OR: add scheduler API to enable integration with GTK main loop instead of doing our own select
+ - use g_main_context_pending, g_main_context_query / g_main_context_check / g_main_context_dispatch
+ and NEVER g_main_loop_run (can this be done? might be the clean way to do this! But how
+ to integrate this with "gtk_main"? Docu says:
+ "It's OK to use the GLib main loop directly instead of gtk_main(), though it involves
+ slightly more typing. See GMainLoop in the GLib documentation."
+ => so maybe it "just works"?
+* SETUP:
+ - design & implement new setup tool

+* DHT: [Nate]
+ - implement DHT service
+ - implement testcases
+ - implement performance tests
+* TRANSPORT:
+ - HTTP backend [MW]
+* ARM: [Safey]
- need to get rid of synchronous API for service starts (cause all kinds of problems)
[=> eliminate for need to tell ARM about service starts most of the time!] [Safey]
- better tracking of which config changes actually need to cause process restarts by ARM.
- better crash management (attach debugging support, capture and analyze
debug output, detect random vs. deterministic crashes)
- shutdown sequence?
-
+* FS: [CG]
+ - datastore reservation (publishing)
+ - search: availability probes
+ - location URIs (publish, search, download)
+ - non-anonymous FS service (needs DHT)
+ + DHT integration for search

- - testbed with churn [Nate]
- - implement testcases for distributed testing [Nate]
- - test basic peer re-configure [Nate]
- - test topology creation [Nate]

* new webpage:
- expand bibliography
- convert documentation pages to books
enable developers to publish TGZs nicely
- port "contact" page
- add content type for "todo" items?
- - DNS activation

-
0.9.x:
-* TRANSPORT:
+* TRANSPORT: [MW]
- SMTP transport backend
- HTTPS transport backend
+ improved HTTPS support in MHD
- implement gnunet-transport (transport configurator / tester)
- UPnP-based IP detection
(Note: build library always, build service when libxml2/etc. are available)
-* FS:
+* FS: [CG]
- Remove KBlocks in gnunet-unindex (see discussion with Kenneth Almquist on gnunet-devs in 9/2009)
- Allow checking of presence of search results and/or content via command-line tools
(add options to gnunet-search / gnunet-download to limit search to local peer)
-* PEERINFO:
+* PEERINFO: [CG]
- expire 'ancient' HELLOs (those without valid addresses AND that
we have not 'used' (for their public keys) in a while; need a way
to track actual 'use')
- make sue we also trigger notifications whenever HELLOs expire
+* VPN
Optimizations:
* TCP:
- should use hash map to look up sessions
-* PEERINFO:
- - api creates many, many short-lived TCP connections; either some
- clients should use the API differently or we need to change the
- API to enable re-use of connections to the service
* STATISTICS:
- should use BIO instead of mmap
* TRANSPORT:
and keeps the code clean), but we should filter strictly *impossible*
incoming addresses! This is for efficiency, not correctness.
- should use hash map to look up Neighbours
+* HOSTLIST:
+ - 'server' uses 'GNUNET_PEERINFO_iterate', should probably switch to notification API
+ (for more instant / up-to-date hostlists at lower cost)
+* DATASTORE (?):
+ - check for duplicates on insertion (currently, same content is frequently
+ stored again [seen with KBLOCKS and SBLOCKS]!)
Minor features:
* TCP:
- [./transport/plugin_transport_tcp.c:391]: (style) struct or union member 'Plugin::address_update_task' is never used (related to issue above)
* TRANSPORT:
- [./transport/gnunet-service-transport.c:173]: (style) struct or union member 'TransportPlugin::rebuild' is never used (related to TCP not refreshing external addresses?)
