580066f2f6 Switch to a StrictNodes config option.
This is step one of handling ExcludedNodes better. This first
step is just to make EntryNodes and ExitNodes do what they did
before.

fcbd65b45c Refactor the safe_str_*() API to make more sense.
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".

0c1b3070cf Now that FOO_free(NULL) always works, remove checks before calling it. 2009-12-12 02:07:59 -05:00

3807db001d *_free functions now accept NULL
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.

5e4d53d535 Remove checks for array existence. (CID 410..415)
In C, the code "char x[10]; if (x) {...}" always takes the true branch of
the if statement.  Coverity notices this now.

In some cases, we were testing arrays to make sure that an operation
we wanted to do would suceed.  Those cases are now always-true.

In some cases, we were testing arrays to see if something was _set_.
Those caes are now tests for strlen(s), or tests for
!tor_mem_is_zero(d,len).

18689317e4 Tweak an assert that shouldn't fire either way.
There were however other places where we used to call this
function that might have caused this to fire. Better
safe than sorry now.

ec05e64a68 Tweak values for when to discard all of our history.
This seems to be happening to me a lot on a garbage DSL line.
We may need to come up with 2 threshholds: a high short onehop
count and a lower longer count.

b918cd8f04 Remove another overzealous assert.
Pretimeouts may have build time data, just no timeout data.

9325b9269c Ignore one-hop circuits for circuit timeout calc
Don't count one-hop circuits when we're estimating how long it
takes circuits to build on average. Otherwise we'll set our circuit
build timeout lower than we should. Bugfix on 0.2.2.2-alpha.

f7e6e852e8 Fix 1108: Handle corrupt or large build times state.
1108 was actually just a fencepost error in an assert,
but making the state file handling code resilient is a
good idea.

cf2afcd707 Fix typos and comments, plus two bugs
A) We were considering a circuit had timed out in the special cases
where we close rendezvous circuits because the final rendezvous
circuit couldn't be built in time.
B) We were looking at the wrong timestamp_created when considering
a timeout.

0352d43917 Move circuitbuildtimeout config check.
We want it to be under our control so it doesn't mess
up initialization. This is likely the cause for
the bug the previous assert-adding commit (09a75ad) was
trying to address.

6eba08e22f Use our variable directly for timeout.
Using CircuitBuildTimeout is prone to issues with SIGHUP, etc.
Also, shuffle the circuit build times array after loading it
in so that newer measurements don't replace chunks of
similarly timed measurements.
