For printf, %f and %lf are synonymous, since floats are promoted to
doubles when passed as varargs. It's only for scanf that we need to
say "%lf" for doubles and "%f" for floats.
Apparenly, some older compilers think it's naughty to say %lf and like
to spew warnings about it.

Original message from bug3393:
check_private_dir() to ensure that ControlSocketsGroupWritable is
safe to use. Unfortunately, check_private_dir() only checks against
the currently running user… which can be root until privileges are
dropped to the user and group configured by the User config option.
The attached patch fixes the issue by adding a new effective_user
argument to check_private_dir() and updating the callers. It might
not be the best way to fix the issue, but it did in my tests.

If rep_hist_buffer_stats_write() was called unitinitalized, we'd leak
memory.

This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.
There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address. I might have missed a couple more too.
This is a fix for bug 3045.

Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

The last entry of the *Maxima values in the state file was inflated by a
factor of NUM_SECS_ROLLING_MEASURE (currently 10). This could lead to
a wrong maximum value propagating through the state file history.
|
|
When reading the bw history from the state file, we'd add the 900-second
value as traffic that occured during one second. Fix that by adding the
average value to each second.
This bug was present since 0.2.0.5-alpha, but was hidden until
0.2.23-alpha when we started using the saved values.
|
|
This fixes the first part of bug 2704. It should occur only rarely when
no bw maxima are known. Bugfix on 0.2.2.23-alpha. Fixes bug 2704.

Some tor relays would report lines like these in their extrainfo
documents:
dirreq-write-history 2011-03-14 16:46:44 (900 s)
This was confusing to some people who look at the stats. It would happen
whenever a relay first starts up, or when a relay has dirport disabled.
Change this so that lines without actual bw entries are omitted.
Implements ticket 2497.

- Document the structure and variables.
- Make circuits_for_buffer_stats into a static variable.
- Don't die horribly if interval_length is 0.
- Remove the unused local_circ_id field.
- Reorder the fields of circ_buffer_stats_t for cleaner alignment layout.

We've got millisecond timers now, we might as well use them.
This change won't actually make circuits get expiered with microsecond
precision, since we only call the expiry functions once per second.
Still, it should avoid the situation where we have a circuit get
expired too early because of rounding.
A couple of the expiry functions now call tor_gettimeofday: this
should be cheap since we're only doing it once per second. If it gets
to be called more often, though, we should onsider having the current
time be an argument again.

Remove some, postpone others, leave some alone. Now the only
remaining XXX022s are ones that seem important to fix or investigate.

It is important to verify the uptime claim of a relay instead of just
trusting it, otherwise it becomes too easy to blackhole a specific
hidden service. rephist already has data available that we can use here.

This should fix a bug that special ran into, where if your state file
didn't record period maxima, it would never decide that it had
successfully parsed itself unless you got lucky with your
uninitialized-variable values.
This patch also tries to improve error messags in the case where a
maximum value legitimately doesn't parse.

also log about running changes, even on a bridge authority.

rransom noticed that a change of ORPort is just as bad as a change of IP
address from a client's perspective, because both mean that the relay is
not available to them while the new information hasn't propagated.
Change the bug1035 fix accordingly.
Also make sure we don't log a bridge's IP address (which might happen
when we are the bridge authority).

Right now, Tor routers don't save the maxima values from the
bw_history_t between sessions. That's no good, since we use those
values to determine bandwidth. This code adds a new BWHist.*Maximum
set of values to the state file. If they're not present, we estimate
them by taking the observed total bandwidth and dividing it by the
period length, which provides a lower bound.
This should fix bug 1863. I'm calling it a feature.

Previously, our state parsing code would fail to parse a bwhist
correctly if the Interval was anything other than the default
hardcoded 15 minutes. This change makes the parsing less incorrect,
though the resulting history array might get strange values in it if
the intervals don't match the one we're using. (That is, if stuff was
generated in 15 minute intervals, and we read it into an array that
expects 30 minute intervals, we're fine, since values can be combined
pairwise. But if we generate data at 30 minute intervals and read it
into 15 minute intervals, alternating buckets will be empty.)
Bugfix on 0.1.1.11-alpha.

The trick of looping from i=0..4 , switching on i to set up some
variables, then running some common code is much better expressed by
just calling a function 4 times with 4 sets of arguments. This should
make the code a little easier to follow and maintain here.

Our checks that we don't exceed the 50 KB size limit of extra-info
descriptors apparently failed. This patch fixes these checks and reserves
another 250 bytes for appending the signature. Fixes bug 2183.

With this patch we stop scheduling when we should write statistics using a
single timestamp in run_scheduled_events(). Instead, we remember when a
statistics interval starts separately for each statistic type in geoip.c
and rephist.c. Every time run_scheduled_events() tries to write stats to
disk, it learns when it should schedule the next such attempt.
This patch also enables all statistics to be stopped and restarted at a
later time.
This patch comes with a few refactorings, some of which were not easily
doable without the patch.
