-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:
-* TESTING-TESTBED [Nate]
-* SETUP
-* DV [Nate]
-* TBENCH
-* TRACEKIT

-* ARM [Safey]
-* FS [Christian]

-0.9.0pre0:
-* 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?)
-* DATASTORE:
- - utilization can (easily, restart?) go out of control (very large), causing
- content expiration job to go crazy and delete everything!
-* FS:
- ! fs_search test fails (hangs) since blocktype was changed from "ANY" to "KBLOCK"!
- (insert blocktype wrong? or what!?)
- ! fs_namespace test fails (hangs), but local fs service has found results; somehow
- they are not passed to the client and/or the shutdown sequence is not working
- - 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! - also good to cover getopt API!)
- - 2-peer download is still too slow (why?)
- - advanced FS API parts
- + search: SBlocks, NBlocks, probes, notify FS-service of known results
- + indexing: index-failure-cleanup
- + gnunet-publish (URI args)
- + gnunet-download (directory)
- + gnunet-search (options, incl. namespace search)
- + gnunet-download (many options)
- + gnunet-directory (man page, options)
- + gnunet-pseudonym (all of it)
- + gnunet-service-fs (remove failing on-demand blocks, hot-path routing,
- load-based routing, nitpicks)
- - implement adv. FS testcases
- - [./fs/gnunet-service-fs.c:208]: (style) struct or union member 'LocalGetContext::results_bf_size' is never used
- - [./fs/gnunet-service-fs.c:501]: (style) struct or union member 'PendingRequest::used_pids_size' is never used
- - [./fs/gnunet-service-fs.c:654]: (style) struct or union member 'ConnectedPeer::last_client_replies' is never used
- - [./fs/gnunet-service-fs.c:669]: (style) struct or union member 'ConnectedPeer::avg_delay' is never used
- - [./fs/gnunet-service-fs.c:675]: (style) struct or union member 'ConnectedPeer::avg_priority' is never used
- - [./fs/gnunet-service-fs.c:688]: (style) struct or union member 'ConnectedPeer::pending_requests' is never used
- - [./fs/gnunet-service-fs.c:694]: (style) struct or union member 'ConnectedPeer::last_p2p_replies_woff' is never used
- - [./fs/gnunet-service-fs.c:700]: (style) struct or union member 'ConnectedPeer::last_client_replies_woff' is never used
-* WWW:
- - Get IPv6 hooked up
- - change DNS
-
-0.9.0pre1:
-* Module features to implement:
- - tbench (RC-pre1)
- + good to have for DV evaluation! [MW]
- - 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!
-* STATISTICS:
- - does not seem to work with timeouts (especially if service is not running)
-* PEERINFO:
- - trust: need *fast* way to check/update trust in peers
- (async peerinfo would not be right; certainly not with the
- current API)
-* UTIL:
- - 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.]
-* FS:
- - datastore reservation (publishing)
- - persistence support (publish, unindex, search, download)
- - download: management/bounding of parallel downloads (for recursive dl.)
- - 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 or new daemon?)
- - GAP improvements:
- + active reply route caching design & implementation of service; gap extension!
-* 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!
-* HELLO:
- - need function to test "equivalency" of HELLOs (or integrate with "merge"?); use in PEERINFO
-
0.9.0pre2:
-* Module features to implement:
- - tracekit (RC-pre2)
- + good to have for DV/DHT evaluation!
- - DHT (RC-pre2)
- + implement DHT service (needs DV, DATACACHE)
- + implement DHT library
- + implement testcases
- + implement performance tests
-* GUIs to implement:
- - fuse (RC-pre2)
-* Plugins to implement:
- - UDP backend (RC-pre2)
- + Fragmentation library
- + actual plugin
- - HTTP backend (RC-pre2)
-* ARM:
- - 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]
+* BIG CORE REFACTORING:
+ - fix transport service API (ATS!)
+ - fix transport plugin API (ATS!)
+ - actually transmit ATS data through core API
+ - fix FS 'latency' ATS function
+ - fix DV
+* Integration test:
+ - test bootstrapping via hostlist + transport/core/dht connect
+
+0.9.0pre3:
+* Determine RC bugs and fix those (release should have no known real bugs)
+* ARM: [CG/Safey]
+ - start_forwarding should not use 'listen_info->service_addr' for connecting since that one can be 0.0.0.0;
+ if it is, we need to use (IPv4 & IPv6) loopback [LRN]
- better tracking of which config changes actually need to cause process restarts by ARM.
- - listen for requests to discover dependencies between services (and avoid
- having to explicitly program start requests)
- - better crash management (attach debugging support, capture and analyze
- debug output, detect random vs. deterministic crashes)
- - shutdown sequence?
-* FS:
- - location URIs (publish, search, download)
- - collection API & tests
- - implement FS performance tests
+ - handle gnunet-arm -k in combination with auto-start magic (what is the right thing here?)
+ - discover dependencies between services
+* CORE:
+ - provide 'reliable' P2P transmission API and queueing infrastructure
+ - Jun 27 11:51:54 core-7670 ERROR Assertion failed at gnunet-service-core.c:3616.
+ (transport notified us that we connected to ourselves!!!; can we still reproduce this?)
+* DHT: [Nate]
+ - track paths content travels (PUT, reply-to-get) in messages,
+ pass to client (client API & protocol already support this!)
+* DATASTORE:
+ - GNUNET_DATASTORE_cancel method not tested
+* TESTING: [Nate]
+ - test basic peer re-configure
+* TOPOLOGY: [Nate]
+ - needs more testing (especially F2F topology) & transport blacklisting
+* TRANSPORT-TCP [MW]:
+ - should use hash map to look up sessions
+* TRANSPORT:
+ - [#1585, #1583, #1582] transport-level disconnect (i.e. TCP) does not cause core-level
+ disconnect in a timely fashion (waits for connection timeout);
+ need to figure a way to make it near-instant in those cases
+ (i.e. rapid reduction in timeout on transport-level disconnect) [CG]
+ => may have been fixed with instant-notification of disconnect
+ to core on session-oriented connection hick-up; not perfect but
+ likely good enough until we get ATS going; still should be tested...
+ => "peers connected (transport)" now instantly goes to ZERO (core statistic),
+ but "established sessions" stays up...
+* NAT/UPNP: [Milan]
+ - finalize API design
+ - [#1609] code clean up
+ - testing
+ - integration with transport service
+ - also do UPnP-based (external) IP detection
+ (Note: build library always, build UPnP service when dependencies like libxml2 are available)
+* FS: [CG]
+ - library:
+ + reconstruct IBLOCKS from DBLOCKS if possible (during download; see FIXME in fs_download)
+ + add support for pushing "already seen" search results to FS service for bloomfilter
+ + use different 'priority' for probe downloads vs. normal downloads
+ - implement multi-peer FS performance tests
+ insert
+ download
+ search
+ unindex

- - test churn generation [Nate]
- - consider changing API for peer-group termination to
- call continuation when done
-
+ - implement anonymity level > 1
+ - re-implement gnunet-auto-share
+* GNUNET-GTK:
+ - finish publish dialog details:
+ + normalize keywords (edit subdialog)
+ - implement download by URI dialog; figure out where to display those downloads!
+ - figure out where in the GUI we should show active uploads/unindex operations and allow aborts
+ - implement unindex operation (use dialog with all indexed files for selection)
+ - events:
+ + search error
+ + publish error
+ + unindex error
+* MONKEY: [Safey]
+ - better crash management (attach debugging support, capture and analyze
+ debug output, detect random vs. deterministic crashes)

+ - good to have for DHT evaluation!
+* DHT: [Nate]

+* BLOCK:
+ - more testing (KBlock, SBlock, NBlock)

+ - exclude content that will "soon" expire from migration?
+ - exclude content with zero-anonymity from gap migration?
+ - make migration data rate & datastore IO-rate configurable
+ - exclude certain peers as targets (based on hash values) in each
+ iteration => same peer can only be picked every n-th iteration

-0.9.x:
-* TRANSPORT:
- - SMTP transport backend
- - HTTPS transport backend
- + improved HTTPS support in MHD
- + actual plugin
+0.9.1:
+* TRANSPORT: [MW]
+ - WiFi transport backend [DB]
+ - implement gnunet-transport (transport configurator / tester)
- Implement method of learning our external addresses from
other peers; need some kind of threshold-based
scheme, limiting both the total number of addresses that we accept
a way to easily "veto" addresses off the list!
=> If MiM attacker uses vetoed address, blacklist the specific IP for
the presumed neighbour!
- - implement gnunet-transport (transport configurator / tester)
- - UPnP-based IP detection
- (Note: build library always, build service when libxml2/etc. are available)
-* FS:
+ - need to periodically probe latency/transport cost changes & possibly switch transport
+ - should use hash map to look up Neighbours (service AND plugins!)
+* DV: [Nate]
+ - proper bandwidth allocation
+ - performance tests
+* PEERINFO:
+ - merge multiple HELLOs of the same peer in the transmission queue
+ (theoretically reduces overhead; bounds message queue size)
+ - merge multiple iteration requests over "all" peers in the queue
+ (theoretically reduces overhead; bounds messgae queue size)
+* STATISTICS: [CG]
+ - should use BIO instead of mmap
+* 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:
+ - use different queue prioritization for probe-downloads vs. normal downloads
+* UTIL: [CG]
+ - allow limiting UNIX socket access by UID/GID
+* GNUNET-GTK: [CG]
+ - add tool bar
+ - do meaningful update to status line (starting up, peer running, #connections, shutdown, ...)
+ - add progress dialog for 'add_dir_at_iter' scan (can take a while...)
+ - NS list in search dialog should use colors to offset our own namespaces from the others
+ - right-clicking on NS list in search dialog should open menu that allows
+ * viewing full meta data
+ * deletion of namespace info
+
+0.9.2:
+* PEERINFO: [NN]
- 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
-
-
-
-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:
- - need to periodically probe latency/transport cost changes & possibly switch transport
- - instantly filter addresses from *other* peers that
- are *equal* to our own address + port (i.e., localhost:2086). We
- no longer filter those for outgoing (helps with loopback testing
- 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) [OPTIMIZATION]
-
-Minor features:
* TCP:
- repeatedly resolve hostname and look up interfaces to determine our own IP
- [./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?)
-* DATACACHE:
- - add stats (# bytes available, # bytes used, # PUTs, # GETs, # GETs satisfied)
+ - WiFi transport backend
+ * nice signal strength adjustment [MW]
+ * energy cost in ATS [MW]
+* BLOCKS:
+ - testcase would be nice
+ - generic block support for DHT
+* STATISTICS:
+ - test notification-based statistics API [LT]
+ - implement statistics GUI (=> start from gnunet-gtk by button!)
+* PEERINFO: [NN]
+ - move peerinfo to new GUI (=> start from gnunet-gtk by button!)
+ - extend peer dialog with green-yellow-red connectivity status lights
+ - extend peer dialog with country flags and names
+0.9.3:
+* SMTP transport backend:
+ - sending (SMTP/SMTPS)
+ - receiving (IMAP/IMAPS/POP?)
+ - rate limiting
+ - improved batching
+ - resource limit integration with ATS
+* VPN [PT]
+ - DNS hijacking
+ - DNS exit
+ - TCP entry/exit
+ - UDP entry/exit

+ - integration with DHT routing
+ - optimized routes (beyond DHT/DV)
+ - "DNS" .gnunet
