4 - TTL/priority calculations
5 - hot-path routing, load considerations
7 - active reply route caching design & implementation of service; gap extension!

74 - good to have for transport/DV evaluation!
76 - write DV API (need to move declarations from dv_api.c to gnunet_dv_service.h!)
77 - implement DV service
78 - implement DV library (looks done)
79 - implement DV transport plugin
81 - implement performance tests (needs tbench)
83 - needs more testing (especially F2F topology) & transport blacklisting
85 - only connect() sockets that are ready (select()) [Nils]
86 [On W32, we need to select after calling socket before doing connect etc.]
87 - add support for UNIX domain sockets [CG]
89 - use g_main_context_set_poll_func to integrate GTK with GNUnet Scheduler!? (YUCK!)
90 - OR: add scheduler API to enable integration with GTK main loop instead of doing our own select
91 - use g_main_context_pending, g_main_context_query / g_main_context_check / g_main_context_dispatch
92 and NEVER g_main_loop_run (can this be done? might be the clean way to do this! But how
93 to integrate this with "gtk_main"? Docu says:
94 "It's OK to use the GLib main loop directly instead of gtk_main(), though it involves
95 slightly more typing. See GMainLoop in the GLib documentation."
96 => so maybe it "just works"?
98 - design & implement new setup tool
102 - good to have for DV/DHT evaluation!
104 - implement DHT service
105 - implement testcases
106 - implement performance tests
110 - better crash management (attach debugging support, capture and analyze
111 debug output, detect random vs. deterministic crashes)
112 - discover dependencies between services
113 => need UNIX domain sockets first!
114 - handle gnunet-arm -k in combination with auto-start magic (what is the right thing here?)
116 - datastore reservation (publishing)
117 - location URIs (publish, search, download)
118 - unindex on index failure
119 - utilize in-line files in meta data always (including in search results or
120 when download is triggered manually and for probes); currently the data is
121 only used when users do a general 'recursive' download
122 - non-anonymous FS service (needs DHT)
123 + DHT integration for search
124 + CS-DHT-functions (DHT-put of LOC)
125 + P2P-functions (DHT-get)
126 - collection API & tests
127 + gnunet-pseudonym (collection support)
128 - implement FS performance tests
134 - improved content selection (not just 'get_random')
137 * Determine RC bugs and fix those!
139 - modify configuration to allow controlling connections for non-local starts
140 - testbed creation with topology (needs working F2F topology)
142 - implement testcases for distributed testing
143 - test basic peer re-configure
144 - test topology creation
145 - test churn generation
146 - consider changing API for peer-group termination to
147 call continuation when done
149 - finalize API design
152 - integration with transport service
153 * MYSQL database backends: [CG]
157 - reconstruct IBLOCKS from DBLOCKS if possible (during download; see FIXME in fs_download)
158 - add support for pushing "already seen" search results to FS service for bloomfilter (can wait)
159 - use different 'priority' for probe downloads vs. normal downloads
161 - better tracking of which config changes actually need to cause process restarts by ARM.
165 - expand bibliography
166 - convert documentation pages to books
167 - update books (especially for developers)
168 - create good Drupal theme for GNUnet
169 - make a NICE download page and figure out how to enable developers to publish TGZs nicely
170 - port "contact" page
171 - add content type for "todo" items?
172 * POSTGRES database backends: [CG]
175 * Determine RC bugs and fix those!
179 - SMTP transport backend
180 - HTTPS transport backend
181 + improved HTTPS support in MHD
183 - Implement method of learning our external addresses from
184 other peers; need some kind of threshold-based
185 scheme, limiting both the total number of addresses that we accept
186 this way as well as requiring multiple confirmations; also, we
187 should possibly try to confirm that the given address works for
188 us ourselves (loopback-style) before adding it to the list
189 + we may be able to simplify WELCOME messages (no need to add
190 addresses there anymore, but may help to learn them there anyway...).
191 + we probably want some kind of voting/counting for learning IP addresses
192 (maybe including IP addresses in ads proportional to how often others
193 report them? we at least need some protection against >64k HELLOs!),
194 + provide a way to give the user a list of "learned" IP addresses and
195 a way to easily "veto" addresses off the list!
196 => If MiM attacker uses vetoed address, blacklist the specific IP for
197 the presumed neighbour!
198 - implement gnunet-transport (transport configurator / tester)
199 - UPnP-based IP detection
200 (Note: build library always, build service when libxml2/etc. are available)
202 - Remove KBlocks in gnunet-unindex (see discussion with Kenneth Almquist on gnunet-devs in 9/2009)
204 - expire 'ancient' HELLOs (those without valid addresses AND that
205 we have not 'used' (for their public keys) in a while; need a way
206 to track actual 'use')
207 - make sue we also trigger notifications whenever HELLOs expire
214 - should use hash map to look up sessions
216 - should use BIO instead of mmap
218 - need to periodically probe latency/transport cost changes & possibly switch transport
219 - should use hash map to look up Neighbours (service AND plugins!)
221 - check for duplicates on insertion (currently, same content is frequently
222 stored again [seen with KBLOCKS and SBLOCKS]!)
224 - merge multiple HELLOs of the same peer in the transmission queue
225 (theoretically reduces overhead; bounds message queue size)
226 - merge multiple iteration requests over "all" peers in the queue
227 (theoretically reduces overhead; bounds messgae queue size)
229 - use different queue prioritization for probe-downloads vs. normal downloads (!?)
233 - repeatedly resolve hostname and look up interfaces to determine our own IP
234 - [./transport/plugin_transport_tcp.c:391]: (style) struct or union member 'Plugin::address_update_task' is never used (related to issue above)
236 - [./transport/gnunet-service-transport.c:173]: (style) struct or union member 'TransportPlugin::rebuild' is never used (related to TCP not refreshing external addresses?)
238 - testcase would be nice...
