2011-09-01Don't update AccountingSoftLimitHitAt on startupSebastian Hahn
Add a "default" state which we use until we've decided whether we're live or hibernating. This allows us to properly track whether we're resuming a hibernation period or not. Fixes bug 2003.
2011-07-21Move entry-only fields from edge_connection_t to entry_connection_tNick Mathewson
Also, refactor the code accordingly.
2011-06-14Make the get_options() return constNick Mathewson
This lets us make a lot of other stuff const, allows the compiler to generate (slightly) better code, and will make me get slightly fewer patches from folks who stick mutable stuff into or_options_t. const: because not every input is an output!

Fix bug 3020.

2010-12-06Fix a bug in calculating wakeup time on 64-bit machines.Nick Mathewson
If you had TIME_MAX > INT_MAX, and your "time_to_exhaust_bw = accountingmax/expected_bandwidth_usage * 60" calculation managed to overflow INT_MAX, then your time_to_consider value could underflow and wind up being rediculously low or high. "Low" was no problem; negative values got caught by the (time_to_consider <= 0) check. "High", however, would get you a wakeup time somewhere in the distant future. The fix is to check for time_to_exhaust_bw overflowing INT_MAX, not TIME_MAX: We don't allow any accounting interval longer than a month, so if time_to_exhaust_bw is significantly larger than 31*24*60*60, we can just clip it. This is a bugfix on 0.0.9pre6, when accounting was first introduced. It fixes bug 2146, unless there are other causes there too. The fix is from boboper. (I tweaked it slightly by removing an assignment that boboper marked as dead, and lowering a variable that no longer needed to be function-scoped.)
2010-12-03Don't crash when accountingmax is set in non-server TorsNick Mathewson
We use a hash of the identity key to seed a prng to tell when an accounting period should end. But thanks to the bug998 changes, clients no longer have server-identity keys to use as a long-term seed in accounting calculations. In any case, their identity keys (as used in TLS) were never never fixed. So we can just set the wakeup time from a random seed instead there. Still open is whether everybody should be random. This patch fixes bug 2235, which was introduced in 0.2.2.18-alpha. Diagnosed with help from boboper on irc.
2010-10-04Maintain separate server and client identity keys when appropriate.Robert Ransom
Fixes a bug described in ticket #988.

2010-09-21Even more accurate handling for shifting accounting intervalsNick Mathewson
Roger correctly pointed out that my code was broken for accounting periods that shifted forwards, since start_of_accounting_period_containing(interval_start_time) would not be equal to interval_start_time, but potentially much earlier.
2010-09-21Bug1789 cleanups suggested by armaNick Mathewson
The significant one is that we look at RelayBandwidthRate if it is set.

2010-09-03Base our expected bw accounting usage on time before soft limitNick Mathewson
Previously, we were also considering the time spent in soft-hibernation. If this was a long time, we would wind up underestimating our bandwidth by a lot, and skewing our wakeup time towards the start of the accounting interval. This patch also makes us store a few more fields in the state file, including the time at which we entered soft hibernation. Fixes bug 1789. Bugfix on 0.0.9pre5.
2010-09-03Use a more sophisticated soft-hibernation-limit calculationNick Mathewson
This should help address bug 1789.

2010-09-03Tolerate a little skew in accounting intervals.Nick Mathewson
This will make changes for DST still work, and avoid double-spending bytes when there are slight changes to configurations. Fixes bug 1511; the DST issue is a bugfix on 0.0.9pre5.

2010-07-18Make the controller act more usefully when GETINFO failsNick Mathewson
Right now it says "552 internal error" because there's no way for getinfo_helper_*() countries to specify an error message. This patch changes the getinfo_helper_*() interface, and makes most of the getinfo helpers give useful error messages in response to failures. This should prevent recurrences of bug 1699, where a missing GeoIPFile line in the torrc made GETINFO ip-to-county/* fail in a "not obvious how to fix" way.
