-0.9.0pre0 [April]:
-* CORE: [CG]
- - "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 slow systems (core or
- transport issue? tracking issue or actual violation?)
-* FS: [CG]
- - Need testcase of command-line tools! - also good to cover getopt API!
- - 2-peer download is still too slow (why? testcases fail on slow systems!)
-* WWW:
- - Get IPv6 hooked up [AK, after April 12th]
- - change DNS [CG, need DNS]
-
-0.9.0pre1:
-* 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.]
-* HELLO: [CG]
- - need function to test "equivalency" of HELLOs (or integrate with "merge"?); use in PEERINFO
-* SETUP:
- - design & implement new setup tool
-* TBENCH: [MW]
- - good to have for transport/DV evaluation!
-* DV: [Nate]
- - write DV API
- - implement DV service
- - implement DV library
- - implement DV transport plugin
- - implement testcases
- - implement performance tests
-* STATISTICS:
- - does not seem to work with timeouts (especially if service is not running)
-* 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; OTOH, we might want to be more explicit about
- allowing/forbidding connects on pre-connect to avoid
- entering connect attempts to just be blacklisted shortly afterwards).
- - 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 (greylist?).
- - 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!
-* 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)
- - 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!
-* GNUNET-GTK:
- - how to integrate scheduler with GTK event loop!?
-
-0.9.0pre2:
-* TRACEKIT: [MW]
- - good to have for DV/DHT evaluation!
-* DHT: [Nate]
- - implement DHT service (needs DV, DATACACHE)
- - implement DHT library
- - 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.
- - 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: [CG]
- - datastore reservation (publishing)
- - search: availability probes
- - location URIs (publish, search, download)
- - non-anonymous FS service (needs DHT)
- + DHT integration for search
- + CS-DHT-functions (DHT-put of LOC)
- + P2P-functions (DHT-get)

-0.9.x:
+0.9.1:
* TRANSPORT: [MW]
- - SMTP transport backend
- - HTTPS transport backend
- + improved HTTPS support in MHD
- + actual plugin
- - 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
- this way as well as requiring multiple confirmations; also, we
- should possibly try to confirm that the given address works for
- us ourselves (loopback-style) before adding it to the list
- + we may be able to simplify WELCOME messages (no need to add
- addresses there anymore, but may help to learn them there anyway...).
- + we probably want some kind of voting/counting for learning IP addresses
- (maybe including IP addresses in ads proportional to how often others
- report them? we at least need some protection against >64k HELLOs!),
- + provide a way to give the user a list of "learned" IP addresses and
- 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)
+ - 'TransmitFunction' requires plugins to have "unbounded" queue (or at least
+ queue of size > 2), might be better to have at MOST one message pending
+ per plugin/target and only send the next one after the continuation was
+ called (or use 'notify_transmit_ready-style API?)
+ - WLAN transport backend [DB]
+ - need to periodically probe latency/transport cost changes & possibly switch transport
+ (working ATS)
+* DV:
+ - 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:
+ - 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: [CG]
+ - use different queue prioritization for probe-downloads vs. normal downloads
+ - re-implement gnunet-auto-share
+ - implement 'GNUNET_FS_file_information_create_from_directory', avoiding
+ code duplication with gnunet-gtk's similar code (!)
+* 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
+ - implement unindex operation (use dialog with all indexed files for selection)
+ - finish publish dialog details:
+ + normalize keywords (edit subdialog)
+ - implement download by URI dialog; figure out where to display those downloads!
+ - add combo box to select desired mime type for search
+* ARM: [CG]
+ - better tracking of which config changes actually need to cause process restarts by ARM.
+ - handle gnunet-arm -k in combination with auto-start magic (what is the right thing here?)
+ - discover dependencies between services
+
+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
-* 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
+* WLAN:
+ - nice signal strength adjustment [MW]
+ - energy cost in ATS [MW]
+* BLOCKS:
+ - testcase would be nice
* 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]
+ - 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
-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)
-* FS:
- - support inline data in directories for recursive file downloads (fs_download)
+0.9.3:
+* SMTP transport backend:
+ - sending (SMTP/SMTPS)
+ - receiving (IMAP/IMAPS/POP?)
+ - rate limiting
+ - improved batching
+ - resource limit integration with ATS
+* VPN
+ - "DNS" .gnunet [MW]
+* MESH:
+ - optimized routes (beyond DHT/DV)
