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

30 May 18 10:53:51 transport-8149 WARNING External protocol violation detected at plugin_transport_tcp.c:1275.
33 - good to have for transport/DV evaluation!
35 - write DV API (need to move declarations from dv_api.c to gnunet_dv_service.h!)
36 - implement DV service
37 - implement DV library (looks done)
38 - implement DV transport plugin
40 - implement performance tests (needs tbench)
42 - needs more testing (especially F2F topology) & transport blacklisting
44 - only connect() sockets that are ready (select()) [Nils]
45 [On W32, we need to select after calling socket before doing connect etc.]
46 - add support for UNIX domain sockets [CG]
48 - use g_main_context_set_poll_func to integrate GTK with GNUnet Scheduler!? (YUCK!)
49 - OR: add scheduler API to enable integration with GTK main loop instead of doing our own select
50 - use g_main_context_pending, g_main_context_query / g_main_context_check / g_main_context_dispatch
51 and NEVER g_main_loop_run (can this be done? might be the clean way to do this! But how
52 to integrate this with "gtk_main"? Docu says:
53 "It's OK to use the GLib main loop directly instead of gtk_main(), though it involves
54 slightly more typing. See GMainLoop in the GLib documentation."
55 => so maybe it "just works"?
57 - design & implement new setup tool
61 - good to have for DV/DHT evaluation!
63 - implement DHT service
65 - implement performance tests
69 - better crash management (attach debugging support, capture and analyze
70 debug output, detect random vs. deterministic crashes)
71 - discover dependencies between services
72 => need UNIX domain sockets first!
73 - handle gnunet-arm -k in combination with auto-start magic (what is the right thing here?)
75 - datastore reservation (publishing)
76 - location URIs (publish, search, download)
77 - unindex on index failure
78 - utilize in-line files in meta data always (including in search results or
79 when download is triggered manually and for probes); currently the data is
80 only used when users do a general 'recursive' download
81 - non-anonymous FS service (needs DHT)
82 + DHT integration for search
83 + CS-DHT-functions (DHT-put of LOC)
84 + P2P-functions (DHT-get)
85 - collection API & tests
86 + gnunet-pseudonym (collection support)
87 - implement FS performance tests
93 - improved content selection (not just 'get_random')
96 * Determine RC bugs and fix those!
98 - modify configuration to allow controlling connections for non-local starts
99 - testbed creation with topology (needs working F2F topology)
101 - implement testcases for distributed testing
102 - test basic peer re-configure
103 - test topology creation
104 - test churn generation
105 - consider changing API for peer-group termination to
106 call continuation when done
108 - finalize API design
111 - integration with transport service
112 * MYSQL database backends: [CG]
116 - reconstruct IBLOCKS from DBLOCKS if possible (during download; see FIXME in fs_download)
117 - add support for pushing "already seen" search results to FS service for bloomfilter (can wait)
118 - use different 'priority' for probe downloads vs. normal downloads
120 - better tracking of which config changes actually need to cause process restarts by ARM.
124 - expand bibliography
125 - convert documentation pages to books
126 - update books (especially for developers)
127 - create good Drupal theme for GNUnet
128 - make a NICE download page and figure out how to enable developers to publish TGZs nicely
129 - port "contact" page
130 - add content type for "todo" items?
131 * POSTGRES database backends: [CG]
134 * Determine RC bugs and fix those!
138 - SMTP transport backend
139 - HTTPS transport backend
140 + improved HTTPS support in MHD
142 - Implement method of learning our external addresses from
143 other peers; need some kind of threshold-based
144 scheme, limiting both the total number of addresses that we accept
145 this way as well as requiring multiple confirmations; also, we
146 should possibly try to confirm that the given address works for
147 us ourselves (loopback-style) before adding it to the list
148 + we may be able to simplify WELCOME messages (no need to add
149 addresses there anymore, but may help to learn them there anyway...).
150 + we probably want some kind of voting/counting for learning IP addresses
151 (maybe including IP addresses in ads proportional to how often others
152 report them? we at least need some protection against >64k HELLOs!),
153 + provide a way to give the user a list of "learned" IP addresses and
154 a way to easily "veto" addresses off the list!
155 => If MiM attacker uses vetoed address, blacklist the specific IP for
156 the presumed neighbour!
157 - implement gnunet-transport (transport configurator / tester)
158 - UPnP-based IP detection
159 (Note: build library always, build service when libxml2/etc. are available)
161 - Remove KBlocks in gnunet-unindex (see discussion with Kenneth Almquist on gnunet-devs in 9/2009)
163 - expire 'ancient' HELLOs (those without valid addresses AND that
164 we have not 'used' (for their public keys) in a while; need a way
165 to track actual 'use')
166 - make sue we also trigger notifications whenever HELLOs expire
173 - should use hash map to look up sessions
175 - should use BIO instead of mmap
177 - need to periodically probe latency/transport cost changes & possibly switch transport
178 - should use hash map to look up Neighbours (service AND plugins!)
180 - check for duplicates on insertion (currently, same content is frequently
181 stored again [seen with KBLOCKS and SBLOCKS]!)
183 - merge multiple HELLOs of the same peer in the transmission queue
184 (theoretically reduces overhead; bounds message queue size)
185 - merge multiple iteration requests over "all" peers in the queue
186 (theoretically reduces overhead; bounds messgae queue size)
188 - use different queue prioritization for probe-downloads vs. normal downloads (!?)
192 - repeatedly resolve hostname and look up interfaces to determine our own IP
193 - [./transport/plugin_transport_tcp.c:391]: (style) struct or union member 'Plugin::address_update_task' is never used (related to issue above)
195 - [./transport/gnunet-service-transport.c:173]: (style) struct or union member 'TransportPlugin::rebuild' is never used (related to TCP not refreshing external addresses?)
197 - testcase would be nice...
