Author	SHA1	Message	Date
Peter Palfrader	beb9e0721a	Stop assuming every authority is a v1 authority svn:r6377	2006-04-10 21:29:29 +00:00
Roger Dingledine	f89b0ea09f	be willing to add our own routerinfo into the routerlist. this means authorities will include themselves in their directories and network-statuses. svn:r6369	2006-04-10 20:00:31 +00:00
Roger Dingledine	b190c451b8	and one more kick to consider all live network statuses for versions svn:r6359	2006-04-10 08:40:16 +00:00
Roger Dingledine	a9e7737c3a	consider all live network statuses we have when deciding whether our version is bad. also, unfix one of the unbugs from before. svn:r6358	2006-04-10 08:37:16 +00:00
Nick Mathewson	71f1a77371	fix bugs in compute_recommended_versions svn:r6356	2006-04-10 08:02:56 +00:00
Roger Dingledine	acc2eb445d	and get rid of an extra variable svn:r6349	2006-04-10 05:48:04 +00:00
Roger Dingledine	ac2070b35b	stop being so picky about when we can start building circuits. now clients are more likely to have circuits up soon after their tor starts. svn:r6346	2006-04-10 05:44:54 +00:00
Nick Mathewson	e258276c2b	Change a dumb interface. Also, increment trusted_dir_server_t.n_networkstatus_failures when an all.z download fails entirely or partially. svn:r6345	2006-04-10 01:35:56 +00:00
Roger Dingledine	b6b534c9dd	quiet a bootstrapping message svn:r6342	2006-04-09 20:19:56 +00:00
Roger Dingledine	b18d20ce32	Here is an attempted fix for directory mirrors that are frozen in fear because they don't have all the networkstatuses. There's no reason not to proceed if all the other checks are ok -- we just shouldn't warn about certain things yet. svn:r6337	2006-04-09 10:10:09 +00:00
Roger Dingledine	a589650496	i like the name FetchUselessDescriptors better. svn:r6327	2006-04-08 21:48:14 +00:00
Roger Dingledine	2a94c8b493	add a new config option FetchUselessRouters, off by default, for when you plan to run "exitlist" on this client and you want to know about even the non-running descriptors. svn:r6326	2006-04-08 21:35:17 +00:00
Roger Dingledine	3a5758e212	If we think of ourselves as authoritative, even if we're not in the DirServers config lines, then we still are. This way we give ourselves the "Authority" flag in our network-status. svn:r6325	2006-04-08 21:19:40 +00:00
Roger Dingledine	557b174b8d	Break out the checks to see if a routerstatus is something we would use. This way when we're deciding if we have "enough" descriptors to start building circuits, we can count them accurately. svn:r6320	2006-04-08 06:56:38 +00:00
Nick Mathewson	7a804572ab	fix an infinite loop; answer a question svn:r6316	2006-04-07 22:55:46 +00:00
Nick Mathewson	c6d010b218	Dont warn about our own status unless weve tried and failed 4 times (or succeeded) for each authority. svn:r6315	2006-04-07 04:52:32 +00:00
Roger Dingledine	c4fb9d22cf	if there's more than one match for router-get-my-nickname, try to pick one that's running. svn:r6313	2006-04-04 03:46:40 +00:00
Roger Dingledine	0825f61102	fix crash bug reported in flyspray 279. svn:r6312	2006-04-04 03:25:36 +00:00
Roger Dingledine	453062b028	fix typo, remove extraneous variable svn:r6311	2006-04-03 11:24:14 +00:00
Roger Dingledine	7198af7fbe	one more edge case that could paralyze a client with fear svn:r6310	2006-04-03 06:59:07 +00:00
Roger Dingledine	a324871603	phrase the threshold comparison in the way we've been phrasing it. these are equivalent, right? svn:r6309	2006-04-03 06:37:35 +00:00
Nick Mathewson	eba6204315	fix some xxxs. svn:r6307	2006-04-03 06:23:24 +00:00
Roger Dingledine	2cb3aeb4e1	another point that needs more thinking svn:r6306	2006-04-03 06:22:54 +00:00
Roger Dingledine	9549d81d95	two more thresholds to look at svn:r6305	2006-04-03 06:10:33 +00:00
Roger Dingledine	64a40b5137	nick: there is no MAX_SERVER_INTERVAL_WITHOUT_REQUEST. true? svn:r6300	2006-04-03 02:20:32 +00:00
Nick Mathewson	4130460f8e	Change networkstatus dl logic: try to have all networkstatuses live; insist on having all of them live or tried-at-least-once. Also, answer a XXXX comment. svn:r6297	2006-04-02 23:02:52 +00:00
Roger Dingledine	1f4d0d2479	When deciding whether a router is Fast or Guard-worthy, consider his advertised BandwidthRate and not just the BandwidthCapacity. This is a bug in 0.1.0.x as well, but let's not bother backporting. svn:r6266	2006-03-28 12:01:58 +00:00
Nick Mathewson	685bceed1c	Make the max number of old descriptors to hold rise with the number of authorities. svn:r6254	2006-03-27 17:29:53 +00:00
Nick Mathewson	cd271dbca9	re-order to avoid free-then-use. Thank goodness tor_free() zeroes things. svn:r6249	2006-03-27 05:27:47 +00:00
Nick Mathewson	c74bd877e2	Oops. We may not have a networkstatus list when we first parse the cached routers. svn:r6248	2006-03-27 05:12:07 +00:00
Nick Mathewson	3e8c9a485f	Fix for "but need_to_mirror=1" annoyance; is bug 273 fixed? svn:r6247	2006-03-27 05:07:57 +00:00
Roger Dingledine	6f08d121d9	Refactor and consolidate addr/exit policies into a new policies.c. Fix some minor bugs and memory leaks along the way. svn:r6246	2006-03-27 02:25:34 +00:00
Roger Dingledine	e20aad8d46	remove obsolete address policy code svn:r6243	2006-03-26 09:38:17 +00:00
Roger Dingledine	f2abd7a69b	fix a wordo, don't be so quick to yell at servers, and ask a question. svn:r6235	2006-03-24 21:11:14 +00:00
Peter Palfrader	444e3b8eb2	Note a magic 2 that probably should be replaced now that we have more dirservers svn:r6232	2006-03-23 20:21:54 +00:00
Roger Dingledine	0d7efbe65d	Note a vulnerability with our current recommended-version concensus building. Make the warnings about invalid and unnamed nodes scale better, and update the text of the warnings. Change router_have_minimum_dir_info() to only be happy when it has enough network-statuses ("more than half") to be willing to actually build circuits. Not yet done: when we fail to get a networkstatus that we wanted, and !router_have_minimum_dir_info(), we should retry it quicker than a whole minute from now. svn:r6227	2006-03-22 06:22:12 +00:00
Roger Dingledine	073d574a3f	Point out a potential DoS flaw in caching untrusted network statuses to disk. We should resolve sometime. svn:r6206	2006-03-21 05:27:35 +00:00
Roger Dingledine	c06e6ddadd	Finish the transition from the word 'verified' to the words 'named' and 'valid'. svn:r6188	2006-03-19 01:21:59 +00:00
Roger Dingledine	67b61fe475	authdirs shouldn't complain about unreachability when they fetch a descriptor from somebody else. this is not the right time to increment the failure count. svn:r6184	2006-03-18 05:37:15 +00:00
Roger Dingledine	581795f41d	auth dir servers were only modifying a server's is_running field when they created a network status. so if nobody asked for a network status, they would never discover that any servers are is_running, so they could never build a circuit. svn:r6183	2006-03-18 01:24:04 +00:00
Roger Dingledine	cf6ba3e76f	let an authdir that's not a naming authdir start even if it doesn't have an approved-routers file. if it does, read it and parse it as usual. svn:r6182	2006-03-18 00:22:23 +00:00
Roger Dingledine	817556315a	Implement router purposes, and don't choose a non-general purpose router when picking random nodes for a circuit. Also implement SETROUTERPURPOSE and modify +POSTDESCRIPTOR. This concludes bug 250 assuming it all works. svn:r6178	2006-03-17 22:08:59 +00:00
Nick Mathewson	053411e827	Comments: cleanups and additions. svn:r6174	2006-03-17 05:50:41 +00:00
Nick Mathewson	215e377224	Only warn about lack of name binding for self if we have tried downloading every networkstatus. svn:r6172	2006-03-17 04:41:57 +00:00
Nick Mathewson	13cf54b9c1	Interim fix for 272: Only warn that we are not named if we have status docs from some naming authorities. svn:r6166	2006-03-15 05:37:27 +00:00
Roger Dingledine	903183ea28	if we as a directory mirror don't know of any v1 directory authorities, then don't try to cache any v1 directories. svn:r6162	2006-03-15 00:10:13 +00:00
Peter Palfrader	a4ec555228	change INET_NTOA_BUF_LEN+1 to INET_NTOA_BUF_LEN add a comment in a few places where we add weird numbers to buffer lengths svn:r6161	2006-03-14 23:40:37 +00:00
Nick Mathewson	bd8ffccae7	More cleanups noticed by weasel; also, remove macros that nobody uses. svn:r6143	2006-03-12 23:31:16 +00:00
Nick Mathewson	474c60b743	Cleanup on time-relaqted constants. New conventions: 1) Surround all constants by (parens), whether we'll be using them in a denominator or not. 2) Express all time periods as products (246060), not as multiplied-out constants (86400). 3) Comments like "(6060) / one hour /" are as pointless as comments like "c = a + b; / set c to the sum of a and b /". Remove them. 4) All time periods should be #defined constants, not given inline. 5) All time periods should have doxygen comments. 6) All time periods, unless specified, are in seconds. It's not necessary to say so. To summarize, the old (lack of) style would allow: #define FOO_RETRY_INTERVAL 6060 /* one hour (seconds) / next_try = now + 3600; The new style is: /* How often do we reattempt foo? / #define FOO_RETRY_INTERVAL (6060) next_try = now + RETRY_INTERVAL; svn:r6142	2006-03-12 22:48:18 +00:00
Roger Dingledine	c8e2a051ac	huge warning sign for esc_router_info() svn:r6124	2006-03-11 17:52:55 +00:00
Nick Mathewson	4d3e709c4b	Use escaped() for remaining cases. svn:r6117	2006-03-11 02:21:30 +00:00
Nick Mathewson	1ce3713889	Possible bug 265 fix: authorities must be more strict than clients about age of acceptable routers; make routers publish every 12 hours; client ROUTER_MAX_AGE must be greater than NETWORKSTATUS_MAX_AGE+authoirty ROUTER_MAX_AGE. svn:r6095	2006-03-08 06:29:52 +00:00
Roger Dingledine	89b07b458b	i missed the other half of that grammar fix svn:r6058	2006-02-21 03:55:47 +00:00
Peter Palfrader	c4f389420c	Improve the "we have been waiting for 1140377851 seconds" log svn:r6046	2006-02-19 19:44:09 +00:00
Roger Dingledine	f6d80d60e0	don't warn when we get a server descriptor from the controller but it's too old. that's not something tor should fix. svn:r6019	2006-02-15 03:01:53 +00:00
Peter Palfrader	5eea6c76df	Split ReachableAddresses into ReachableDirAddresses and ReachableORAddresses svn:r6009	2006-02-13 21:17:20 +00:00
Roger Dingledine	259c65ab08	the last of the log convention conversion. finally. svn:r6005	2006-02-13 10:33:00 +00:00
Roger Dingledine	b7781ea208	bugfix: we were ignoring the IS_FAST flag in the directory status, meaning we were willing to pick trivial-bandwidth nodes for "fast" connections. svn:r5992	2006-02-13 00:09:30 +00:00
Roger Dingledine	3c4e68488b	Clients now honor the "guard" flag in the router status when picking entry guards, rather than looking at is_fast or is_stable. Now dirservers can change how they define it and clients will automatically use their new definition. svn:r5979	2006-02-12 03:43:39 +00:00
Roger Dingledine	85a64b4fd0	get our grammar right when complaining about un-recommended versions svn:r5950	2006-02-09 06:08:59 +00:00
Roger Dingledine	5f051574d5	Happy new year! svn:r5949	2006-02-09 05:46:49 +00:00
Nick Mathewson	e5a574ce2e	Move "sort list of versions" logic into routerparse.c; make version-checking code say which versions it would have accepted. (not tested.) svn:r5927	2006-02-06 05:04:27 +00:00
Roger Dingledine	a9c87fe251	more typos and nits svn:r5918	2006-02-05 05:28:52 +00:00
Nick Mathewson	157e6a025a	Stupid cut-and-paste bug. svn:r5917	2006-02-05 05:11:24 +00:00
Roger Dingledine	d602d0d298	cosmetic fix svn:r5915	2006-02-05 03:42:04 +00:00
Roger Dingledine	640882c76c	clean up tabs and wide-lines from weasel's commit svn:r5914	2006-02-05 03:23:16 +00:00
Roger Dingledine	53f86cdf5d	fix bug: we were caching the newest descriptor for each server, well, forever. i imagine this just keeps growing in size. svn:r5912	2006-02-05 02:07:28 +00:00
Peter Palfrader	390bbb0a0c	Try to make tor work better through squid: Limit number of descriptors we fetch to 96 (was 128 previously). We limit this number even when we do not have a http proxy explicitly configured as some people mistakenly believe transparent proxies are a neat idea. svn:r5901	2006-02-03 15:17:48 +00:00
Roger Dingledine	92ef9e37e7	Add a new config option ExitPolicyRejectPrivate which defaults to 1. This means all exit policies will begin with rejecting private addresses, unless the server operator explicitly turns it off. Also, make our code to remove redundancies in the exit policy smarter, so it can detect "reject foo, reject bar, reject *" patterns. Lastly, we can get rid of the "exit policy implicitly accepts" code, since we make everything more explicit now. svn:r5888	2006-02-01 03:53:52 +00:00
Peter Palfrader	bf514e5dc5	Try to fix policy_includes_addr_mask_implicitly() svn:r5886	2006-02-01 02:52:55 +00:00
Peter Palfrader	61ea27620a	Also catch 0/8 in exit_policy_implicitly_allows_local_networks() svn:r5885	2006-02-01 02:31:27 +00:00
Roger Dingledine	2eabf190e9	make it louder when we're running an unrecommended version. also, we need to tell them what versions are recommended. i'll add that to the todo. svn:r5859	2006-01-24 03:45:58 +00:00
Nick Mathewson	9f42c9d650	Make dirservers generate a separate "guard" flag to mean, "would make a good entry guard". Make clients parse it and vote on it. svn:r5856	2006-01-24 00:31:16 +00:00
Roger Dingledine	b9540285af	remove unused code svn:r5847	2006-01-20 20:54:42 +00:00
Roger Dingledine	d5acef191c	add another assert to make sure we're not scribbling on the stack. svn:r5837	2006-01-17 04:14:04 +00:00
Nick Mathewson	1057516a07	Clients should not download descriptors for non-running descriptors. svn:r5830	2006-01-16 20:52:30 +00:00
Nick Mathewson	2dd566d5d5	Indirect access to the signed_descriptor field to make it easier to keep them lazily on disk. svn:r5827	2006-01-12 18:04:17 +00:00
Roger Dingledine	0e51d5d274	When the controller was submitting a descriptor, we were checking to make sure some network-status we had referred to it, and refusing it if not. This is bad for people who want to insert descriptors that aren't part of the current Tor network. Now we accept them, and also give a more useful warn message if we ask a dir mirror for a given descriptor and it gives us one we weren't expecting. svn:r5824	2006-01-12 03:43:39 +00:00
Nick Mathewson	eb78295e4e	Fix memory leak in routerlist_remove_old_routers(). svn:r5790	2006-01-11 03:58:07 +00:00
Roger Dingledine	7d1f675c85	entry nodes are now entry guards. this is our last easy chance for a wholesale change. heave ho. svn:r5782	2006-01-10 22:42:44 +00:00
Nick Mathewson	43a4f8c7f3	Be more aggressive about throwing away expired router descriptors: they are of no use to anybody. Better still: dont serve expired descriptors by fingerprint. The only people who ask for them are busted 0.1.1.10 Tors that will throw them away and re-request them after 30 minutes. svn:r5762	2006-01-10 04:57:12 +00:00
Nick Mathewson	56c55c343e	When picking a random directory, prefer non-authorities if any are known. svn:r5761	2006-01-09 23:39:07 +00:00
Nick Mathewson	e30516f33f	Fix bug 236: caches should cache up to 16 unrecognized network-status docs. svn:r5754	2006-01-08 21:26:33 +00:00
Nick Mathewson	50b6b3258d	Dont call directory_get_from_dirserver when you have a particular dirserver in mind; remove fetch-from-authority special-case in directory_get_from_dirserver. svn:r5741	2006-01-06 18:19:17 +00:00
Roger Dingledine	6aaa92f736	short-circuit half the cost of node-picking in the general case. svn:r5732	2006-01-05 10:59:46 +00:00
Roger Dingledine	f8a59965a1	cleanups, and remove some unreachable code. svn:r5727	2006-01-04 06:43:03 +00:00
Roger Dingledine	485aa9415d	authdirs now stop whining so loudly about bad descriptors that they fetch from other dirservers. now when there's a log complaint, it's for sure from a freshly uploaded descriptor. svn:r5726	2006-01-04 04:42:10 +00:00
Roger Dingledine	f6f65c66b5	oh, it was supposed to compile? svn:r5721	2006-01-03 13:12:17 +00:00
Roger Dingledine	da06f3553c	don't try to build circuits until we have 3 running servers; and for networks that are very small, having more than a quarter of the descriptors is much harder than having equal to or more than a quarter of the descriptors -- follow the spec. svn:r5720	2006-01-03 13:09:49 +00:00
Roger Dingledine	9af33ef39c	when we choose not to use a server descriptor from our cache, don't log it so loudly. svn:r5713	2006-01-03 10:42:20 +00:00
Roger Dingledine	5947388968	Finish implementing config's EntryNodes and StrictEntryNodes option. The logging is way verbose for now. svn:r5683	2005-12-31 06:32:57 +00:00
Roger Dingledine	0dc8e284f8	load balance a bit better by taking some load off the really fast servers. this might slow things down more, or it might not. hm. svn:r5681	2005-12-30 04:46:43 +00:00
Roger Dingledine	c051e82f69	fix a typo svn:r5680	2005-12-30 04:44:10 +00:00
Nick Mathewson	fc850273bd	Appease some verbose GCC warnings. svn:r5679	2005-12-29 20:25:53 +00:00
Roger Dingledine	dbd7b97eff	helper nodes are dead. long live entry nodes. (config options EntryNodes and StrictEntryNodes still not implemented.) svn:r5673	2005-12-28 09:07:31 +00:00
Nick Mathewson	9ef54a3d0c	Make directory caches a little less chatty when logging svn:r5662	2005-12-27 06:05:54 +00:00
Nick Mathewson	fa0d5aa894	Make insert_old try hard to never add a duplicate. svn:r5661	2005-12-27 05:58:12 +00:00
Nick Mathewson	ece9865020	Implement new directory logic: download by descriptor digest, not by key digest. Caches try to download all listed digests from authorities; clients try to download "best" digests from caches. svn:r5659	2005-12-27 05:26:03 +00:00
Roger Dingledine	34249e8861	fix segfault when specifying DirServer without nickname (reported by weasel) svn:r5614	2005-12-18 22:45:27 +00:00
Nick Mathewson	6b5fc9d46f	Instead of "Network down", say "Is your network connection down?" svn:r5607	2005-12-15 22:10:03 +00:00
Roger Dingledine	edde3fcf25	ah ha, that variable was static. not useless after all. svn:r5604	2005-12-15 21:44:23 +00:00
Roger Dingledine	002c9b3589	clean up a lot message, and remove a line that does nothing. svn:r5603	2005-12-15 21:41:27 +00:00
Nick Mathewson	cf8c70b79c	fix compile svn:r5600	2005-12-15 21:38:59 +00:00
Nick Mathewson	280c62314e	Make clients look at the fast and stable flags in networkstatus, not at the bandwidth and uptime declared in the router descriptors. svn:r5599	2005-12-15 21:30:57 +00:00
Roger Dingledine	3489066433	put back in a todo comment, so we don't forget. svn:r5598	2005-12-15 21:26:52 +00:00
Nick Mathewson	24e79df0b6	Whitespace fixes; comments. svn:r5596	2005-12-15 21:17:40 +00:00

Roger Dingledine	25e1ad02fa	implement weasel's suggestion to fix the bug that newly bootstrapped tor networks couldn't do hidden services until they had nodes with high uptime: if you're trying to pick a node for your circuit and you demand uptime or capacity and nothing works, then abandon your need for uptime and capacity. svn:r5589	2005-12-15 09:53:00 +00:00
Nick Mathewson	7af95e5c06	When we mark a router as down, also mark its local_routerstatus as not running. This way, we do not use directories that are believed to be down. svn:r5587	2005-12-14 22:05:10 +00:00
Nick Mathewson	9482b1b9d5	Choose directory servers from routerstatus list, not from routerinfo list. This way, as soon was we have a networkstatus, we can ask a cache to give us routers, rather than needing to ask the directories. svn:r5586	2005-12-14 22:00:58 +00:00

Roger Dingledine	afb1c79879	Leave options->DirServers alone -- if the user didn't specify any, just add the default ones directly to the trusted dirserver list.

Nick Mathewson	e3adcbdb95	Big commit: clients start downloading and using network-statuses. Only caches need to get running-routers; nobody needs to parse, store, or use it. Same for the router-status line in the directories. Add many #if 0's that can get removed once I'm convinced they don't contain anything I'm forgetting. Start all newly-parsed routers as non-running and non-valid; update them from the list of network statuses. Update all routers when a new networkstatus comes in.

Don't actually look at it yet. dirserv.c, routerlist.c: - Remove expired networkstatus objects. or.h: - Make some booleans into bitfields - Add prototypes routerlist.c: - Sort networkstatus list by publication time - Function to remove old (older than 10 days) networkstatus objects. - Function to set a list of routerinfo_ts' status info from the current set of networkstatus objects. - Function to tell which routerinfos we need to download based no the current set of networkstatus objects. - Do not launch a networkstatus download if a redundant one is in progress. routerparse.c: - Keep router entries in networkstatus sorted by digest. svn:r5012	2005-09-12 06:56:42 +00:00

Roger Dingledine	ef6c9d18e7	New circuit building strategy: keep a list of ports that we've used in the past 6 hours, and always try to have 2 circuits open or on the way that will handle each such port. (We can extend this to include addresses if exit policies shift to require that.) Seed us with port 80 so web browsers won't complain that Tor is "slow to start up". This was necessary because our old circuit building strategy just involved counting circuits, and as time went by we would build up a big pile of circuits that had peculiar exit policies (e.g. only exit to 9001-9100) which would take up space in the circuit pile but never get used. Fix router_compare_addr_to_addr_policy: it was not treating a port of * as always matching, so we were picking reject : nodes as exit nodes too. If you haven't used a clean circuit in an hour, throw it away, just to be on the safe side. This means after 6 hours a totally unused Tor client will have no circuits open. svn:r3078	2004-12-05 07:10:08 +00:00

Roger Dingledine	9bf9ca4d09	bugfix: add a circ->resolving_streams field, and make dns resolving streams not actually in the connection_array until they're done resolving. bugfix: actually complain if we duplicate mark-for-close a circuit add more logging for relay ends that claim dns resolve failed, so we can find out why they're not being retried. svn:r1798	2004-05-06 11:08:04 +00:00

Nick Mathewson	8169da5c30	Don't use Tor version 0.0.5 for intro/rendezvous points. (We don't need to worry about 0.0.4 or earlier, because nobody is running them any more.) svn:r1533	2004-04-07 21:36:03 +00:00

Roger Dingledine	7793078dff	alice can now look up bob's service descriptor, choose an intro point, connect to it, choose a rend point, connect to it and establish a cookie, get an ack from the rendezvous point, and know when both circs are ready for her. APConns don't use conn->purpose anymore don't initiate a renddesc lookup if one is already in progress also fix a buffer overflow in nickname parsing (only exploitable by the operator though) svn:r1471	2004-04-05 00:47:48 +00:00
Nick Mathewson	137b577bbd	Refactor the heck out of crypto interface: admit that we will stick with one ciphersuite at a time, make const things const, and stop putting openssl in the headers. svn:r1458	2004-04-03 02:40:30 +00:00

Roger Dingledine	89d9d80e76	Store options->Address as IP, not hostname And figure it out while reading config, not every time you rebuild the descriptor svn:r1226	2004-03-04 01:53:56 +00:00
Roger Dingledine	4716d4d871	bugfix: only warn about an unrouter router after we've fetched a directory svn:r1178	2004-02-29 01:31:33 +00:00
Roger Dingledine	d3e9afda27	When it can't resolve any dirservers, it was useless from then on. Now it reloads the RouterFile (or default dirservers) if it has no dirservers. svn:r1130	2004-02-26 22:56:36 +00:00
Roger Dingledine	0b27ae0c2d	if the default torrc isn't there, just use some default defaults plus provide an internal dirservers file if they don't have one having no config files will make it easier to run on windows svn:r1124	2004-02-26 21:25:51 +00:00

Roger Dingledine	b669b1d57c	oh, and make it compile still need to make a decision about per-connection rate limiting (take it out? update it?) svn:r984	2004-01-11 07:41:01 +00:00
Roger Dingledine	5086300815	split the token bucket into 'rate' and 'burst' params we're not entirely migrated to burst yet, for backward compatibility note some win32 probable-bugs clean up routerlist.c svn:r982	2004-01-10 23:40:38 +00:00
