  41. - better buffer approaches in openssl
  42. - shipping Tor with its own integrated allocator.
  43. N - Write a draft research proposal for how to safely collect and
  44. aggregate some GeoIP data from non-bridge entry nodes, or conclude
  45. that we don't know how to do it safely while still being useful
  46. and explain why.
  47. I - Translation portal
  48. - Vidalia translations (via launchpad?)
  49. - Vidalia installer translations
  50. - Torbutton translations (via babelzilla?)
  51. - Centralized instructions for how to help translate
  52. - Continue managing the tor-translations team to keep the Tor
  53. website translated
  54. - End of May
  55. S - More TorBrowser work
  56. - Integrate pidgin and OTR
  57. - move portablefirefox nsi goo into vidalia as appropriate
  58. - Figure out (or give up on) how to run Tor Browser and ordinary
  59. Firefox side-by-side.
  60. - mid June
  61. R - SRI stuff
  62. - mid June
  63. - More TorBrowser work
  64. S - Firefox extension framework for Torbrowser build-time
  65. S - Progress bar during startup, including some "timeout" events to
  66. indicate when Tor's unlikely to succeed at startup.

  68. - Let Vidalia notice them and change its appearance
  69. S - Enumerate and analyze traces left when running from USB
  70. R - Finish tor-doc-bridge.wml
  71. - More bridgedb work:
  72. R - Get the dkimproxy patch in
  73. ? - Brainstorm about safe but effective ways for vidalia to
  74. auto-update its user's bridges via Tor in the background.
  75. NR - Include "stable" bridge and "port 443" bridge and "adequately
  76. new version" bridge free in every specially marked
  77. box!^W^W^Woutput batch.
  78. N - Detect proxies and treat them as the same address
  79. - More back-end work:
  80. N - If we decided above that we know how to collect geoip data for
  81. non bridge relays, deploy that plan.
  82. N - Additional TLS-camouflage work (spoofing FF cipher suite, etc.)
  83. - spoof the cipher suites
  84. - spoof the extensions list
  85. - red-team testing (a.k.a, look at a packet dump and compare),
  86. - investigate the feasibility of handing connections off to a
  87. local apache if they don't look like Tor or if they don't
  88. portknock or whatever.
  89. R - Get closer to downloading far fewer descriptors
  90. - Instrument the code to track how many descriptors we download vs how
  91. many times we extend a circuit.
  92. - Write a proposal for how to fetch far fewer descriptors; assess
  93. anonymity attacks, like from looking at the size of the
  94. descriptor you fetch.
  95. I - Translation portal
  96. - Torbutton webpage
  97. o Torbrowser webpage
  98. - Tor website
  99. - check.torproject.org
  100. - should we i18nize polipo's error messages too?
  101. - August
  102. I - Auto update
  103. o Vidalia learns when Tor thinks it should be updated
  104. R - Tor status events should suggest a new version to switch to
  105. I - Figure out a good PKI, document the design, assess security issues:
  106. "write a proposal"
  107. - Vidalia fetches the new one via Tor when possible, but fetches
  108. it without Tor "when necessary", whatever that means.
  109. - Give an interface for notifying the user, and letting her
  110. decide to fetch and decide to swap out the old Tor for the new.
  111. - Do the same for Polipo
  112. - and for Vidalia itself
  113. =======================================================================
  114. For Tor 0.2.0.x-rc:
  115. R - Figure out the autoconf problem with adding a fallback consensus.
  116. R - add a geoip file
  117. W - figure out license
  118. R - let bridges set relaybandwidthrate as low as 5kb
  119. R - bug: if we launch using bridges, and then stop using bridges, we
  120. still have our bridges in our entryguards section, and may use them.
  121. . make it easier to set up a private tor network on your own computer
  122. is very hard.
  123. R . FAQ entry which is wrong
  124. N . geoip caching and publishing for bridges
  125. d Track consecutive time up, not time since last-forgotten IP.
  126. - Mention in dir-spec.txt
  127. - Mention in control-spec.txt
  128. D have normal relays report geoip stats too.
  129. D different thresholds for bridges than for normal relays.
  130. o bridge relays round geoip stats *up*, not down.
  131. R - bridge communities
  132. . spec
  133. . deploy
  134. - man page entries for Alternate*Authority config options
  135. Things we'd like to do in 0.2.0.x:
  136. N - document the "3/4 and 7/8" business in the clients fetching consensus
  137. documents timeline.
  138. R - then document the bridge user download timeline.
  139. N - Before the feature freeze:
  140. - 105+TLS, if possible.
  141. . TLS backend work
  142. . Enable.
  143. - Test
  144. o Verify version negotiation on client
  145. o Verify version negotiation on server
  146. o Verify that client->server connection becomes open
  147. - Verify that server->server connection becomes open and
  148. authenticated.
  149. - Verify that initiator sends no cert in first stage of TLS
  150. handshake.
  151. - NETINFO fallout
  152. - Don't extend a circuit over a noncanonical connection with
  153. mismatched address.
  154. - Learn our outgoing IP address from netinfo cells?
  155. - Bugs.
  156. - Bug reports Roger has heard along the way that don't have enough
  157. details/attention to solve them yet.
  158. - arma noticed that when his network went away and he tried
  159. a new guard node and the connect() syscall failed to it,
  160. the guard wasn't being marked as down. 0.2.0.x.
  161. - after being without network for 12 hours, arma's tor decided
  162. it couldn't fetch any network statuses, and never tried again
  163. even when the network came back and arma clicked on things.
  164. also 0.2.0.
  165. R - for above two, roger should turn them into flyspray entry.
  166. - Proposals:
  167. o 101: Voting on the Tor Directory System (plus 103)
  168. N - Use if-modified-since on consensus download
  169. - Controller support
  170. D GETINFO to get consensus
  171. N - Event when new consensus arrives
  172. . 111: Prioritize local traffic over relayed.
  173. R - Merge into tor-spec.txt.
  174. =======================================================================
  175. Planned for 0.2.1.x:
  176. - Refactoring:
  177. . Make cells get buffered on circuit, not on the or_conn.
  178. . Switch to pool-allocation for cells?
  179. N - Benchmark pool-allocation vs straightforward malloc.
  180. N - Adjust memory allocation logic in pools to favor a little less
  181. slack memory.
  182. . Remove socketpair-based bridges conns, and the word "bridge". (Use
  183. shared (or connected) buffers for communication, rather than sockets.)
  184. . Implement
  185. N - Handle rate-limiting on directory writes to linked directory
  186. connections in a more sensible manner.
  187. Nick thinks he did this already?
  188. N - Find more ways to test this.
  189. (moria doesn't rate limit, so testing on moria not so good.)
  190. - Documentation
  191. - HOWTO for DNSPort. See tup's wiki page.
  192. . Document transport and natdport in a good HOWTO.
  193. N - Quietly document NT Service options: revise (or create) FAQ entry
  194. P - Make documentation realize that location of system configuration file
  195. will depend on location of system defaults, and isn't always /etc/torrc.
  196. P - Figure out why dll's compiled in mingw don't work right in WinXP.
  197. P - create a "make win32-bundle" for vidalia-privoxy-tor-torbutton bundle
  198. - Things that have been bugging Nick
  199. - Make better use of multi-core machines: Do AES crypto and
  200. compression in worker threads
  201. - Maybe use jemalloc from freebsd via firefox 3, once its windows
  202. and osx ports are more mature.
  203. - MMap the cached-descriptors.new file as well as the regular ones
  204. - Actually use SSL_shutdown to close our TLS connections.
  205. - Refactor the HTTP logic so the functions aren't so large.
  206. - Get a "use less buffer ram" patch into openssl.
  207. - Get IOCP patch into libevent
  208. - Use libevent's evdns code where applicable.
  209. - Refactor buf_read and buf_write to have sensible ways to return
  210. error codes after partial writes
  211. - Improve unit test coverage
  212. - Logging domains.
  213. - get rid of the v1 directory stuff (making, serving, and caching).
  214. - perhaps replace it with a "this is a tor server" stock webpage.
  215. - the v2dir flag isn't used for anything anymore. right?
  216. - even clients run rep_hist_load_mtbf_data(). this wastes memory.
  217. - steven's plan for replacing check.torproject.org with a built-in
  218. answer by tor itself.
  219. - a status event for when tor decides to stop fetching directory info
  220. if the client hasn't clicked recently: then make the onion change too.
  221. - bridge communities with local bridge authorities:
  222. - clients who have a password configured decide to ask their bridge
  223. authority for a networkstatus
  224. - be able to have bridges that aren't in your torrc. save them in
  225. state file, etc.
  226. - router_choose_random_node() has a big pile of args. make it "flags".
  227. - Consider if we can solve: the Tor client doesn't know what flags
  228. its bridge has (since it only gets the descriptor), so it can't
  229. make decisions based on Fast or Stable.
  230. - anonymity concern: since our is-consensus-fresh-enough check is
  231. sloppy so clients will actually work when a consensus wasn't formed,
  232. does that mean that if users are idle for 5 hours and then click on
  233. something, we will immediately use the old descriptors we've got,
  234. while we try fetching the newer descriptors?
  235. related to bug 401.
  236. . Finish path-spec.txt
  237. - More prominently, we should have a recommended apps list.
  238. - recommend pidgin (gaim is renamed)
  239. - unrecommend IE because of ftp:// bug.
  240. - we should add a preamble to tor-design saying it's out of date.
  241. - Refactor networkstatus generation:
  242. - Include "v" line in getinfo values.
  243. - config option __ControllerLimit that hangs up if there are a limit
  244. of controller connections already.
  245. - Features (other than bridges):
  246. - Audit how much RAM we're using for buffers and cell pools; try to
  247. trim down a lot.
  248. - Base relative control socket paths on datadir.
  249. - Make TrackHostExits expire TrackHostExitsExpire seconds after their
  250. *last* use, not their *first* use.
  251. - Plan a switch to polipo. Perhaps we'll offer two http proxies in
  252. the future.
  253. - Consider creating special Tor-Polipo-Vidalia test packages,
  254. requested by Dmitri Vitalev (does torbrowser meet this need?)
  255. - Create packages for Nokia 800, requested by Chris Soghoian
  256. - mirror tor downloads on (via) tor dir caches
  257. . spec
  258. - deploy
  259. - interface for letting soat modify flags that authorities assign
  260. . spec
  261. - proposal 118 if feasible and obvious
  262. - Maintain a skew estimate and use ftime consistently.
  263. - Tor logs the libevent version on startup, for debugging purposes.
  264. This is great. But it does this before configuring the logs, so
  265. it only goes to stdout and is then lost.
  266. - Deprecations:
  267. - can we deprecate 'getinfo network-status'?
  268. - can we deprecate the FastFirstHopPK config option?
  269. - Bridges:
  270. . Bridges users (rudimentary version)
  271. . Ask all directory questions to bridge via BEGIN_DIR.
  272. - use the bridges for dir fetches even when our dirport is open.
  273. - drop 'authority' queries if they're to our own identity key; accept
  274. them otherwise.
  275. - give extend_info_t a router_purpose again
  276. d Limit to 2 dir, 2 OR, N SOCKS connections per IP.
  277. - Or maybe close connections from same IP when we get a lot from one.
  278. - Or maybe block IPs that connect too many times at once.
  279. - Do TLS connection rotation more often than "once a week" in the
  280. extra-stable case.
  281. - Streamline how we pick entry nodes: Make choose_random_entry() have
  282. less magic and less control logic.
  283. - when somebody uses the controlport as an http proxy, give them
  284. a "tor isn't an http proxy" error too like we do for the socks port.
  285. - we try to build 4 test circuits to break them over different
  286. servers. but sometimes our entry node is the same for multiple
  287. test circuits. this defeats the point.
  288. - enforce a lower limit on MaxCircuitDirtiness and CircuitBuildTimeout.
  289. - configurable timestamp granularity. defaults to 'seconds'.
  290. - consider making 'safelogging' extend to info-level logs too.
  291. - we should consider a single config option TorPrivateNetwork that
  292. turns on all the config options for running a private test tor
  293. network. having to keep updating all the tools, and the docs,
  294. just isn't working.
  295. - consider whether a single Guard flag lets us distinguish between
  296. "was good enough to be a guard when we picked it" and "is still
  297. adequate to be used as a guard even after we've picked it". We should
  298. write a real proposal for this.
  299. - switch out privoxy in the bundles and replace it with polipo.
  300. - make the new tls handshake blocking-resistant.
  301. - figure out some way to collect feedback about what countries are using
  302. bridges, in a way that doesn't screw anonymity too much.
  303. - let tor dir mirrors proxy connections to the tor download site, so
  304. if you know a bridge you can fetch the tor software.
  305. - more strategies for distributing bridge addresses in a way that
  306. doesn't rely on knowing somebody who runs a bridge for you.
  307. - A way to adjust router status flags from the controller. (How do we
  308. prevent the authority from clobbering them soon afterward?)
  309. - Bridge authorities should do reachability testing but only on the
  310. purpose==bridge descriptors they have.
  311. - Clients should estimate their skew as median of skew from servers
  312. over last N seconds.
  313. - Investigate RAM use in Tor servers.
  314. - Start on the WSAENOBUFS solution.
  315. - Start on Windows auto-update for Tor
  316. - Stuff that weasel wants:
  317. - Make Tor able to chroot itself
  318. o allow it to load an entire config file from control interface
  319. - document LOADCONF
  320. - log rotation (and FD passing) via control interface
  321. - chroot yourself, including inhibit trying to read config file
  322. and reopen logs, unless they are under datadir.
  323. Deferred from 0.2.0.x:
  324. - Proposals
  325. - 113: Simplifying directory authority administration
  326. - 110: prevent infinite-length circuits (phase one)
  327. - 118: Listen on and advertise multiple ports:
  328. - Tor should be able to have a pool of outgoing IP addresses that it is
  329. able to rotate through. (maybe. Possible overlap with proposal 118.)
  330. - config option to publish what ports you listen on, beyond
  331. ORPort/DirPort. It should support ranges and bit prefixes (?) too.
  332. (This is very similar to proposal 118.)
  333. - 117: IPv6 Exits
  334. - Internal code support for ipv6:
  335. o Clone ipv6 functions (inet_ntop, inet_pton) where they don't exist.
  336. - Most address variables need to become tor_addr_t
  337. - Teach resolving code how to handle ipv6.
  338. - Teach exit policies about ipv6 (consider ipv4/ipv6 interaction!)
  339. - Features
  340. - Let controller set router flags for authority to transmit, and for
  341. client to use.
  342. - add an 'exit-address' line in the descriptor for servers that exit
  343. from something that isn't their published address.
  344. - More work on AvoidDiskWrites?
  345. - Features
  346. - Make a TCP DNSPort
  347. - Protocol work
  348. - MAYBE kill stalled circuits rather than stalled connections. This is
  349. possible thanks to cell queues, but we need to consider the anonymity
  350. implications.
  351. - Implement TLS shutdown properly when possible.
  352. - Bugs
  353. - If the client's clock is too far in the past, it will drop (or just not
  354. try to get) descriptors, so it'll never build circuits.
  355. - Refactoring
  356. - Make resolves no longer use edge_connection_t unless they are actually
  357. _on_ a socks connection: have edge_connection_t and (say)
  358. dns_request_t both extend an edge_stream_t, and have p_streams and
  359. n_streams both be linked lists of edge_stream_t.
  360. - Generate torrc.{complete|sample}.in, tor.1.in, the HTML manual, and the
  361. online config documentation from a single source.
  362. - Move all status info out of routerinfo into local_routerstatus. Make
  363. "who can change what" in local_routerstatus explicit. Make
  364. local_routerstatus (or equivalent) subsume all places to go for "what
  365. router is this?"
  366. - Blocking/scanning-resistance
  367. - It would be potentially helpful to respond to https requests on
  368. the OR port by acting like an HTTPS server.
  369. - Do we want to maintain our own set of entryguards that we use as
  370. next hop after the bridge? Open research question; let's say no
  371. for 0.2.0 unless we learn otherwise.
  372. - Some mechanism for specifying that we want to stop using a cached
  373. bridge.
  374. - Build:
  375. - Detect correct version of libraries from autoconf script.
  376. =======================================================================
  377. Future versions:
  378. - deprecate router_digest_is_trusted_dir() in favor of
  379. router_get_trusteddirserver_by_digest()
  380. - See also Flyspray tasks.
  381. - See also all OPEN/ACCEPTED proposals.
  382. - See also all items marked XXXX and FFFF in the code.
  383. - Protocol:
  384. - Our current approach to block attempts to use Tor as a single-hop proxy
  385. is pretty lame; we should get a better one.
  386. - Allow small cells and large cells on the same network?
  387. - Cell buffering and resending. This will allow us to handle broken
  388. circuits as long as the endpoints don't break, plus will allow
  389. connection (tls session key) rotation.
  390. - Implement Morphmix, so we can compare its behavior, complexity,
  391. etc. But see paper breaking morphmix.
  392. - Other transport. HTTP, udp, rdp, airhook, etc. May have to do our own
  393. link crypto, unless we can bully DTLS into it.
  394. - Need a relay teardown cell, separate from one-way ends.
  395. (Pending a user who needs this)
  396. - Handle half-open connections: right now we don't support all TCP
  397. streams, at least according to the protocol. But we handle all that
  398. we've seen in the wild.
  399. (Pending a user who needs this)
  400. - Directory system
  401. - BEGIN_DIR items
  402. X turn the received socks addr:port into a digest for setting .exit
  403. - handle connect-dir streams that don't have a chosen_exit_name set.
  404. - Have a "Faster" status flag that means it. Fast2, Fast4, Fast8?
  405. - Add an option (related to AvoidDiskWrites) to disable directory
  406. caching. (Is this actually a good idea??)
  407. - Add d64 and fp64 along-side d and fp so people can paste status
  408. entries into a url. since + is a valid base64 char, only allow one
  409. at a time. Consider adding to controller as well.
  410. - Some back-out mechanism for auto-approval on authorities
  411. - a way of rolling back approvals to before a timestamp
  412. - Consider minion-like fingerprint file/log combination.
  413. - Have new people be in limbo and need to demonstrate usefulness
  414. before we approve them.
  415. - Hidden services:
  416. - Standby/hotswap/redundant hidden services.
  417. . Update the hidden service stuff for the new dir approach. (Much
  418. of this will be superseded by 114.)
  419. - switch to an ascii format, maybe sexpr?
  420. - authdirservers publish blobs of them.
  421. - other authdirservers fetch these blobs.
  422. - hidserv people have the option of not uploading their blobs.
  423. - you can insert a blob via the controller.
  424. - and there's some amount of backwards compatibility.
  425. - teach clients, intro points, and hidservs about auth mechanisms.
  426. - come up with a few more auth mechanisms.
  427. - auth mechanisms to let hidden service midpoint and responder filter
  428. connection requests.
  429. - Let each hidden service (or other thing) specify its own
  430. OutboundBindAddress?
  431. - Hidserv offerers shouldn't need to define a SocksPort
  432. - Server operation
  433. X When we notice a 'Rejected: There is already a named server with
  434. this nickname' message... or maybe instead when we see in the
  435. networkstatuses that somebody else is Named with the name we
  436. want: warn the user, send a STATUS_SERVER message, and fall back
  437. to unnamed.
  438. - If the server is spewing complaints about raising your ulimit -n,
  439. we should add a note about this to the server descriptor so other
  440. people can notice too.
  441. - When we hit a funny error from a dir request (eg 403 forbidden),
  442. but tor is working and happy otherwise, and we haven't seen many
  443. such errors recently, then don't warn about it.
  444. - Controller
  445. - Implement missing status events and accompanying getinfos
  446. - DIR_REACHABLE
  447. - BAD_DIR_RESPONSE (Unexpected directory response; maybe we're behind
  448. a firewall.)
  449. - BAD_PROXY (Bad http or https proxy)
  450. - UNRECOGNIZED_ROUTER (a nickname we asked for is unavailable)
  451. - Status events related to hibernation
  452. - something about failing to parse our address?
  453. from resolve_my_address() in config.c
  454. - sketchy OS, sketchy threading
  455. - too many onions queued: threading problems or slow CPU?
  456. - Implement missing status event fields:
  457. - TIMEOUT on CHECKING_REACHABILITY
  458. - GETINFO status/client, status/server, status/general: There should be
  459. some way to learn which status events are currently "in effect."
  460. We should specify which these are, what format they appear in, and so
  461. on.
  462. - More information in events:
  463. - Include bandwidth breakdown by conn->type in BW events.
  464. - Change circuit status events to give more details, like purpose,
  465. whether they're internal, when they become dirty, when they become
  466. too dirty for further circuits, etc.
  467. - Change stream status events analogously.
  468. - Expose more information via getinfo:
  469. - import and export rendezvous descriptors
  470. - Review all static fields for additional candidates
  471. - Allow EXTENDCIRCUIT to unknown server.
  472. - We need some way to adjust server status, and to tell tor not to
  473. download directories/network-status, and a way to force a download.
  474. - Make everything work with hidden services
  475. - Performance/resources
  476. - per-conn write buckets
  477. - separate config options for read vs write limiting
  478. (It's hard to support read > write, since we need better
  479. congestion control to avoid overfull buffers there. So,
  480. defer the whole thing.)
  481. - Look into pulling serverdescs off buffers as they arrive.
  482. - Rate limit exit connections to a given destination -- this helps
  483. us play nice with websites when Tor users want to crawl them; it
  484. also introduces DoS opportunities.
  485. - Consider truncating rather than destroying failed circuits,
  486. in order to save the effort of restarting. There are security
  487. issues here that need thinking, though.
  488. - Handle full buffers without totally borking
  489. - Rate-limit OR and directory connections overall and per-IP and
  490. maybe per subnet.
  491. - Misc
  492. - Hold-open-until-flushed now works by accident; it should work by
  493. design.
  494. - Display the reasons in 'destroy' and 'truncated' cells under
  495. some circumstances?
  496. - Make router_is_general_exit() a bit smarter once we're sure what
  497. it's for.
  498. - Automatically determine what ports are reachable and start using
  499. those, if circuits aren't working and it's a pattern we
  500. recognize ("port 443 worked once and port 9001 keeps not
  501. working").
  502. - Security
  503. - some better fix for bug #516?
  504. - don't do dns hijacking tests if we're reject *:* exit policy?
  505. (deferred until 0.1.1.x is less common)
  506. - Directory guards
  507. - Mini-SoaT:
  508. - Servers might check certs for known-good ssl websites, and if
  509. they come back self-signed, declare themselves to be
  510. non-exits. Similar to how we test for broken/evil dns now.
  511. - Authorities should try using exits for http to connect to some
  512. URLS (specified in a configuration file, so as not to make the
  513. List Of Things Not To Censor completely obvious) and ask them
  514. for results. Exits that don't give good answers should have
  515. the BadExit flag set.
  516. - Alternatively, authorities should be able to import opinions
  517. from Snakes on a Tor.
  518. - More consistent error checking in router_parse_entry_from_string().
  519. I can say "banana" as my bandwidthcapacity, and it won't even squeak.
  520. - Bind to random port when making outgoing connections to Tor servers,
  521. to reduce remote sniping attacks.
  522. - Audit everything to make sure rend and intro points are just as
  523. likely to be us as not.
  524. - Do something to prevent spurious EXTEND cells from making
  525. middleman nodes connect all over. Rate-limit failed
  526. connections, perhaps?
  527. - DoS protection: TLS puzzles, public key ops, bandwidth exhaustion.
  528. - Needs thinking
  529. - Now that we're avoiding exits when picking non-exit positions,
  530. we need to consider how to pick nodes for internal circuits. If
  531. we avoid exits for all positions, we skew the load balancing. If
  532. we accept exits for all positions, we leak whether it's an
  533. internal circuit at every step. If we accept exits only at the
  534. last hop, we reintroduce Lasse's attacks from the Oakland paper.
  535. - Windows server usability
  536. - Solve the ENOBUFS problem.
  537. - make tor's use of openssl operate on buffers rather than sockets,
  538. so we can make use of libevent's buffer paradigm once it has one.
  539. - make tor's use of libevent tolerate either the socket or the
  540. buffer paradigm; includes unifying the functions in connect.c.
  541. - We need a getrlimit equivalent on Windows so we can reserve some
  542. file descriptors for saving files, etc. Otherwise we'll trigger
  543. asserts when we're out of file descriptors and crash.
  544. - Merge code from Urz into libevent
  545. - Make Tor use evbuffers.
  546. - Documentation
  547. - a way to generate the website diagrams from source, so we can
  548. translate them as utf-8 text rather than with gimp. (svg? or
  549. imagemagick?)
  550. . Flesh out options_description array in src/or/config.c
  551. . multiple sample torrc files
  552. . figure out how to make nt service stuff work?
  553. . Document it.
  554. - Refactor tor man page to divide generally useful options from
  555. less useful ones?
  556. - Add a doxygen style checker to make check-spaces so nick doesn't drift
  557. too far from arma's undocumented styleguide. Also, document that
  558. styleguide in HACKING. (See r9634 for example.)
  559. - exactly one space at beginning and at end of comments, except i
  560. guess when there's line-length pressure.
  561. - if we refer to a function name, put a () after it.
  562. - only write <b>foo</b> when foo is an argument to this function.
  563. - doxygen comments must always end in some form of punctuation.
  564. - capitalize the first sentence in the doxygen comment, except
  565. when you shouldn't.
  566. - avoid spelling errors and incorrect comments. ;)
  567. - Packaging
  568. - The Debian package now uses --verify-config when (re)starting,
  569. to distinguish configuration errors from other errors. Perhaps
  570. the RPM and other startup scripts should too?
  571. - add a "default.action" file to the tor/vidalia bundle so we can
  572. fix the https thing in the default configuration:
  573. http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#PrivoxyWeirdSSLPort
  574. - Related tools
  575. - Patch privoxy and socks protocol to pass strings to the browser.
  576. =======================================================================
  577. Documentation, non-version-specific.
  578. - Specs
  579. - Mark up spec; note unclear points about servers
  580. NR - write a spec appendix for 'being nice with tor'
  581. - Specify the keys and key rotation schedules and stuff
  582. - Mention controller libs someplace.
  583. - Remove need for HACKING file.
  584. - document http://wiki.noreply.org/noreply/TheOnionRouter/TransparentProxy on freebsd and osx
  585. P - figure out why x86_64 won't build rpms from tor.spec
  586. P - figure out rpm spec files for bundles of vidalia-tor-polipo
  587. P - figure out polipo install scripts for bundles of vidalia-tor-polipo on osx, win32
  588. - figure out selinux policy for tor
  589. P - change packaging system to more automated and specific for each
  590. platform, suggested by Paul Wouter
  591. P - Setup repos for redhat and suse rpms & start signing the rpms the
  592. way package management apps prefer
  593. Website:
  594. J . tor-in-the-media page
  595. - Which bundles include Torbutton? Change the docs/tor-doc-foo pages
  596. so they admit that Torbutton is in them too. Change the download
  597. page too.
  598. - The OS X bundle screenshots are from forever ago -- they don't
  599. include Torbutton, they still say it's tor.eff.org, etc.
  600. - Should we still be telling you how to use Safari on OS X for Tor,
  601. given all the holes that Torbutton-dev solves on Firefox?
  602. P - Figure out licenses for website material.
  603. (Phobos reccomends the Open Publication License with Option A at
  604. http://opencontent.org/openpub/)
  605. P - put the logo on the website, in source form, so people can put it on
  606. stickers directly, etc.
  607. P - put the source image for the stickers on the website, so people can
  608. print their own
  609. P - figure out a license for the logos and docs we publish (trademark
  610. figures into this)
  611. (Phobos reccomends the Open Publication License with Option A at
  612. http://opencontent.org/openpub/)
  613. R - make a page with the hidden service diagrams.
  614. P - ask Jan/Jens to be the translation coordinator? add to volunteer page.
  615. I - add a page for localizing all tor's components.
  616. - It would be neat if we had a single place that described _all_ the
  617. tor-related tools you can use, and what they give you, and how well they
  618. work. Right now, we don't give a lot of guidance wrt
  619. torbutton/foxproxy/privoxy/polipo in any consistent place.
  620. P - create a 'blog badge' for tor fans to link to and feature on their
  621. blogs. A sample can be found at http://interloper.org/tmp/tor/tor-button.png
  622. - Tor mirrors
  623. - make a mailing list with the mirror operators
  624. - make an automated tool to check /project/trace/ at mirrors to
  625. learn which ones are lagging behind.
  626. - auto (or manually) cull the mirrors that are broken; and
  627. contact their operator?
  628. - a set of instructions for mirror operators to make their apaches
  629. serve our charsets correctly, and bonus points for language
  630. negotiation.
  631. - figure out how to load-balance the downloads across mirrors?
  632. - ponder how to get users to learn that they should google for
  633. "tor mirrors" if the main site is blocked.
  634. - find a mirror volunteer to coordinate all of this
