* Fold timestamp_created into highres_createdNick Mathewson2010-10-15
| | | | | | | There's no reason to keep a time_t and a struct timeval to represent the same value: highres_created.tv_sec was the same as timestamp_created. This should save a few bytes per circuit.
* Initial conversion to use node_t throughout our codebase.Nick Mathewson2010-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A node_t is an abstraction over routerstatus_t, routerinfo_t, and microdesc_t. It should try to present a consistent interface to all of them. There should be a node_t for a server whenever there is * A routerinfo_t for it in the routerlist * A routerstatus_t in the current_consensus. (note that a microdesc_t alone isn't enough to make a node_t exist, since microdescriptors aren't usable on their own.) There are three ways to get a node_t right now: looking it up by ID, looking it up by nickname, and iterating over the whole list of microdescriptors. All (or nearly all) functions that are supposed to return "a router" -- especially those used in building connections and circuits -- should return a node_t, not a routerinfo_t or a routerstatus_t. A node_t should hold all the *mutable* flags about a node. This patch moves the is_foo flags from routerinfo_t into node_t. The flags in routerstatus_t remain, but they get set from the consensus and should not change. Some other highlights of this patch are: * Looking up routerinfo and routerstatus by nickname is now unified and based on the "look up a node by nickname" function. This tries to look only at the values from current consensus, and not get confused by the routerinfo_t->is_named flag, which could get set for other weird reasons. This changes the behavior of how authorities (when acting as clients) deal with nodes that have been listed by nickname. * I tried not to artificially increase the size of the diff here by moving functions around. As a result, some functions that now operate on nodes are now in the wrong file -- they should get moved to nodelist.c once this refactoring settles down. This moving should happen as part of a patch that moves functions AND NOTHING ELSE. * Some old code is now left around inside #if 0/1 blocks, and should get removed once I've verified that I don't want it sitting around to see how we used to do things. There are still some unimplemented functions: these are flagged with "UNIMPLEMENTED_NODELIST()." I'll work on filling in the implementation here, piece by piece. I wish this patch could have been smaller, but there did not seem to be any piece of it that was independent from the rest. Moving flags forces many functions that once returned routerinfo_t * to return node_t *, which forces their friends to change, and so on.

* Clear cell queues when marking or truncating a circuit.Nick Mathewson2010-07-30
| | | | | | | | | At best, this patch helps us avoid sending queued relayed cells that would get ignored during the time between when a destroy cell is sent and when the circuit is finally freed. At worst, it lets us release some memory a little earlier than it would otherwise. Fix for bug #1184. Bugfix on 0.2.0.1-alpha.

* Don't cannibalize one-hop circuitsSebastian Hahn2010-06-04
| | | | | | | | In rare cases, we could cannibalize a one-hop circuit, ending up with a two-hop circuit. This circuit would not be actually used, but we should prevent its creation in the first place. Thanks to outofwords and swissknife for helping to analyse this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two big changes here: - We store active circuits in a priority queue for each or_conn, rather than doing a linear search over all the active circuits before we send each cell. - Rather than multiplying every circuit's cell-ewma by a decay factor every time we send a cell (thus normalizing the value of a current cell to 1.0 and a past cell to alpha^t), we instead only scale down the cell-ewma every tick (ten seconds atm), normalizing so that a cell sent at the start of the tick has value 1.0).
| * | Favor quiet circuits when choosing which order to relay cells in.Can Tang2009-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each circuit is ranked in terms of how many cells from it have been relayed recently, using a time-weighted average. This patch has been tested this on a private Tor network on PlanetLab, and gotten improvements of 12-35% in time it takes to fetch a small web page while there's a simultaneous large data transfer going on simultaneously.

| * | Refactor the safe_str_*() API to make more sense.Nick Mathewson2009-12-15
| | | | | | | | | | | | | | | | | | The new rule is: safe_str_X() means "this string is a piece of X information; make it safe to log." safe_str() on its own means "this string is a piece of who-knows-what; make it safe to log".

* | | *_free functions now accept NULLSebastian Hahn2009-12-12
|/ / | | | | | | | | | | | | | | Some *_free functions threw asserts when passed NULL. Now all of them accept NULL as input and perform no action when called that way. This gains us consistence for our free functions, and allows some code simplifications where an explicit null check is no longer necessary.

| | | | | | | | | | | | | | | | | | If the networkstatus consensus tells us that we should use a negative circuit package window, ignore it. Otherwise we'll believe it and then trigger an assert. Also, change the interface for networkstatus_get_param() so we don't have to lookup the consensus beforehand.
