* Use strcmpstart() instead of strcmp(x,y,strlen(y)).
* Warn the user if the managed proxy failed to launch.
* Improve function documentation.
* Use smartlist_len() instead of n_unconfigured_proxies.
* Split managed_proxy_destroy() to managed_proxy_destroy()
and managed_proxy_destroy_with_transports().
* Constification.
It turns out that it wasn't enough to set the configuration to
"auto", since the correct behavior for "auto" had been disabled in
microdesc.c. :p
(Hasn't been in a release yet, so doesn't need a changes entry.)
Also remove a few other related warnings that could occur during the ssl
handshake. We do this because the relay operator can't do anything about
them, and they aren't their fault.
Starting with Lion, Apple decided to deprecate the system openssl. We
can start requiring users to install their own openssl once OS X doesn't
ship with it anymore.
Now we track *which* stream with ISO_STREAM set is associated to a
particular circuit, so that we won't think that stream is incompatible
with its circuit and launch another one a second later, and we use that
same field to mark circuits which have had an ISO_STREAM stream attached
to them, so that we won't ever put a second stream on that circuit.
Fixes bug 3695.
Only write a bridge-stats string if bridge stats have been
initialized. This behavior is similar to dirreq-stats, entry-stats,
etc.
Also add a few unit tests for the bridge-stats code.
This patch separates the generation of a dirreq-stats string from
actually writing it to disk. The new geoip_format_dirreq_stats()
generates a dirreq-stats string that geoip_dirreq_stats_write() writes
to disk. All the state changing (e.g., resetting the dirreq-stats
history and initializing the next measurement interval) takes place in
geoip_dirreq_stats_write(). That allows us to finally test the
dirreq-stats code better.
Now that formatting the buffer-stats string is separate from writing
it to disk, we can also decouple the logic to extract stats from
circuits and finally write some unit tests for the history code.
The new rep_hist_format_buffer_stats() generates a buffer-stats string
that rep_hist_buffer_stats_write() writes to disk. All the state
changing (e.g., resetting the buffer-stats history and initializing
the next measurement interval) takes place in
rep_hist_buffer_stats_write(). That allows us to finally test the
buffer-stats code better.
So far, if we didn't see a single circuit, we refrained from
generating a cell-stats string and logged a warning. Nobody will
notice the warning, and people will wonder why there's no cell-stats
string in the extra-info descriptor. The better behavior is to
generate a cell-stats string with all zeros.
Right now, we append statistics to files in the stats/ directory for
half of the statistics, whereas we overwrite these files for the other
half. In particular, we append buffer, dirreq, and entry stats and
overwrite exit, connection, and bridge stats.
Appending to files was useful when we didn't include stats in extra-info
descriptors, because otherwise we'd have to copy them away to prevent
Tor from overwriting them.
But now that we include statistics in extra-info descriptors, it makes
no sense to keep the old statistics forever. We should change the
behavior to overwriting instead of appending for all statistics.
Implements #2930.
