3 - trust: need *fast* way to check/update trust in peers
4 (async peerinfo would not be right; certainly not with the current API)
6 - needs to re-try connecting after disconnect (currently, it
7 initially triggers a connection request, but if that connection
8 fails / goes down, it does not retry in a timely fashion;
9 cause seems to be the 'greylist_after_attempt' being set to 1h,
10 which is rather long -- and should probably be adjusted based on
11 the number of connections / known peers & use some form of back-off)
12 - If the topology daemon crashes, peers that were put on the
13 blacklist with transport will never be removed from it (until
14 transport service dies); we should use the blacklist notification
15 API to learn about the exact set of blacklisted peers at all times
16 (FIXME: the transport_api implementation of blacklisting
17 also does not work nicely for this since it won't let us know about
18 disconnect-reconnect events and the implicit whitelisting
19 that might happen here; that's not so bad since we will
20 re-blacklist on pre-connect attempts anyway, so this is
21 a minor issue; OTOH, we might want to be more explicit about
22 allowing/forbidding connects on pre-connect to avoid
23 entering connect attempts to just be blacklisted shortly afterwards).
24 - needs more testing (especially F2F topology)
26 - support recursive download even if filename is NULL and we hence
27 do not generate files on disk (use temp_filename)
28 - bound parallelism (# fs downloads)
29 - distinguish in performance tracking and event signalling between
30 downloads that are actually running and those that are merely in the queue
31 - persistence support (publish, unindex, search, download)
32 - active migration support (in fs or in datastore or new daemon?)
33 - gnunet-service-fs (hot-path routing, load-based routing, nitpicks)
34 - [gnunet-service-fs.c:208]: member 'LocalGetContext::results_bf_size' is never used
35 - [gnunet-service-fs.c:501]: member 'PendingRequest::used_pids_size' is never used
36 - [gnunet-service-fs.c:654]: member 'ConnectedPeer::last_client_replies' is never used
37 - [gnunet-service-fs.c:669]: member 'ConnectedPeer::avg_delay' is never used
38 - [gnunet-service-fs.c:675]: member 'ConnectedPeer::avg_priority' is never used

40 - [gnunet-service-fs.c:694]: member 'ConnectedPeer::last_p2p_replies_woff' is never used
41 - [gnunet-service-fs.c:700]: member 'ConnectedPeer::last_client_replies_woff' is never used
43 + active reply route caching design & implementation of service; gap extension!
45 - good to have for transport/DV evaluation!
47 - write DV API (need to move declarations from dv_api.c to gnunet_dv_service.h!)
48 - implement DV service
49 - implement DV library (looks done)
50 - implement DV transport plugin
52 - implement performance tests
54 - only connect() sockets that are ready (select()) [Nils]
55 [On W32, we need to select after calling socket before doing connect etc.]
57 - use g_main_context_set_poll_func to integrate GTK with GNUnet Scheduler!? (YUCK!)
58 - OR: add scheduler API to enable integration with GTK main loop instead of doing our own select
59 - use g_main_context_pending, g_main_context_query / g_main_context_check / g_main_context_dispatch
60 and NEVER g_main_loop_run (can this be done? might be the clean way to do this! But how
61 to integrate this with "gtk_main"? Docu says:
62 "It's OK to use the GLib main loop directly instead of gtk_main(), though it involves
63 slightly more typing. See GMainLoop in the GLib documentation."
64 => so maybe it "just works"?
66 - design & implement new setup tool
70 - good to have for DV/DHT evaluation!
72 - implement DHT service
74 - implement performance tests
78 - need to get rid of synchronous API for service starts (cause all kinds of problems)
79 [=> eliminate for need to tell ARM about service starts most of the time!] [Safey]
80 - better tracking of which config changes actually need to cause process restarts by ARM.
81 - listen for requests to discover dependencies between services (and avoid
82 having to explicitly program start requests)
83 - better crash management (attach debugging support, capture and analyze
84 debug output, detect random vs. deterministic crashes)
87 - datastore reservation (publishing)
88 - search: availability probes
89 - location URIs (publish, search, download)
90 - non-anonymous FS service (needs DHT)
91 + DHT integration for search
92 + CS-DHT-functions (DHT-put of LOC)
93 + P2P-functions (DHT-get)
94 - collection API & tests
95 + gnunet-pseudonym (collection support)
96 - implement FS performance tests
103 * Determine RC bugs and fix those!
105 - modify configuration to allow controlling connections for non-local starts
106 - testbed creation with topology (needs working F2F topology)
108 - implement testcases for distributed testing
109 - test basic peer re-configure
110 - test topology creation
111 - test churn generation
112 - consider changing API for peer-group termination to
113 call continuation when done
115 - finalize API design
118 - integration with transport service
119 * MYSQL database backends: [CG]
125 - expand bibliography
126 - convert documentation pages to books
127 - update books (especially for developers)
128 - create good Drupal theme for GNUnet
129 - make a NICE download page and figure out how to
130 enable developers to publish TGZs nicely
131 - port "contact" page
132 - add content type for "todo" items?
133 * POSTGRES database backends: [CG]
136 * Determine RC bugs and fix those!
140 - SMTP transport backend
141 - HTTPS transport backend
142 + improved HTTPS support in MHD
144 - Implement method of learning our external addresses from
145 other peers; need some kind of threshold-based
146 scheme, limiting both the total number of addresses that we accept
147 this way as well as requiring multiple confirmations; also, we
148 should possibly try to confirm that the given address works for
149 us ourselves (loopback-style) before adding it to the list
150 + we may be able to simplify WELCOME messages (no need to add
151 addresses there anymore, but may help to learn them there anyway...).
152 + we probably want some kind of voting/counting for learning IP addresses
153 (maybe including IP addresses in ads proportional to how often others
154 report them? we at least need some protection against >64k HELLOs!),
155 + provide a way to give the user a list of "learned" IP addresses and
156 a way to easily "veto" addresses off the list!
157 => If MiM attacker uses vetoed address, blacklist the specific IP for
158 the presumed neighbour!
159 - implement gnunet-transport (transport configurator / tester)
160 - UPnP-based IP detection
161 (Note: build library always, build service when libxml2/etc. are available)
163 - Remove KBlocks in gnunet-unindex (see discussion with Kenneth Almquist on gnunet-devs in 9/2009)
164 - Allow checking of presence of search results and/or content via command-line tools
165 (add options to gnunet-search / gnunet-download to limit search to local peer)
167 - expire 'ancient' HELLOs (those without valid addresses AND that
168 we have not 'used' (for their public keys) in a while; need a way
169 to track actual 'use')
170 - make sue we also trigger notifications whenever HELLOs expire
177 - should use hash map to look up sessions
179 - should use BIO instead of mmap
181 - need to periodically probe latency/transport cost changes & possibly switch transport
182 - instantly filter addresses from *other* peers that
183 are *equal* to our own address + port (i.e., localhost:2086). We
184 no longer filter those for outgoing (helps with loopback testing
185 and keeps the code clean), but we should filter strictly *impossible*
186 incoming addresses! This is for efficiency, not correctness.
187 - should use hash map to look up Neighbours
189 - 'server' uses 'GNUNET_PEERINFO_iterate', should probably switch to notification API
190 (for more instant / up-to-date hostlists at lower cost)
192 - check for duplicates on insertion (currently, same content is frequently
193 stored again [seen with KBLOCKS and SBLOCKS]!)
197 - repeatedly resolve hostname and look up interfaces to determine our own IP
198 - [./transport/plugin_transport_tcp.c:391]: (style) struct or union member 'Plugin::address_update_task' is never used (related to issue above)
200 - [./transport/gnunet-service-transport.c:173]: (style) struct or union member 'TransportPlugin::rebuild' is never used (related to TCP not refreshing external addresses?)
202 - add stats (# bytes available, # bytes used, # PUTs, # GETs, # GETs satisfied)
204 - support inline data in directories for recursive file downloads (fs_download)
