- pid, stdout/stderr_pipe now encapsulated in process_handle
- read_all replaced by tor_read_all_from_process_stdin/stderr
- waitpid replaced by tor_get_exit_code
Untested on *nix
For some reason, --with-libminiupnpc-dir doesn't work on Windows, so this
hardcodes /local/lib as the path in which libminiupnpc.a can be found.
Also, libminiupnpc needs libws2_32 and libiphlpapi under Windows, so this
hardcodes these libraries when building the ./configure test program.
These changes almost certainly break *nix, so should be fixed before merge.
Previously we were using router_get_by_id(foo) to test "do we have a
descriptor that will let us make an anonymous circuit to foo". But
that isn't right for microdescs: we should have been using node_t.
Fixes bug 3601; bugfix on 0.2.3.1-alpha.
Instead, use compare_tor_addr_to_node_policy everywhere.
One advantage of this is that compare_tor_addr_to_node_policy can
better distinguish 0.0.0.0 from "unknown", which caused a nasty bug
with microdesc users.
Previously, we had an issue where we'd treat an unknown address as
0, which turned into "0.0.0.0", which looked like a rejected
address. This meant in practice that as soon as we started doing
comparisons of unknown uint32 addresses to short policies, we'd get
'rejected' right away. Because of the circumstances under which
this would be called, it would only happen when we had local DNS
cached entries and we were looking to launch new circuits.
Rationale: right now there seems to be no way for our bootstrap
status to dip under 100% once it has reached 100%. Thus, recording
broken connections after that point is useless, and wastes memory.
If at some point in the future we allow our bootstrap level to go
backwards, then we should change this rule so that we disable
recording broken connection states _as long as_ the bootstrap status
is 100%.
- We were reporting the _bottom_ N failing states, not the top N.
- With bufferevents enabled, we logged all TLS states as being "in
bufferevent", which isn't actually informative.
- When we had nothing to report, we reported nothing too loudly.
- Also, we needed documentation.
