3f683aadcd When making a tempdir for windows unit tests, avoid an extra backslash
The extra \ is harmless, but mildly unpleasant.

Fixes 12392; bugfix on 0.2.2.25-alpha where we started using
GetTempDir().  Based on a patch by Gisle Vanem.

4da4c4c63f Apply GeoIPExcludeUnknown before checking transitions
Otherwise, it always seems as though our Exclude* options have
changed, since we're comparing modified to unmodified values.

Patch from qwerty1. Fixes bug 9801. Bugfix on 0.2.4.10-alpha, where
GeoIPExcludeUnknown was introduced.

d504a4e36f src/or/connection.c: expose bucket_millis_empty for bufferevents test
Currently tor fails to build its test when enabled with bufferevents
because an #ifndef USE_BUFFEREVENTS hides bucket_millis_empty() and
friends.  This is fine if we don't run tests, but if we do, we need
these functions in src/or/libtor-testing.a when linking src/test/test.

This patch moves the functions outside the #ifndef and exposes them.

32495ee309 Add another 8387 diagnostic
When we run into bug 8387 (if we run into it again), report when we
last called circuit_expire_old_circuits_clientside().  This will let
us know -- if my fix for 8387 doesn't work -- whether my diagnosis
was at least correct.

Suggested by Andrea.

6150741791 Fixed fgets_eagain unit test.
On a non-blocking pipe fgets sets EAGAIN when it encounters partial lines. No
error is set on full lines or EOF. EOF is reached when the writing end of the
pipe is closed. Partial lines and full lines are both returned by fgets, EOF
results in NULL.

Mention of this behaviour can be found in #1903 and #2045.

58f4200789 Thread support is now required
Long ago we supported systems where there was no support for
threads, or where the threading library was broken. We shouldn't
have do that any more: on every OS that matters, threads exist, and
the OS supports running threads across multiple CPUs.

This resolves tickets 9495 and 12439.  It's a prerequisite to making
our workqueue code work better, since sensible workqueue
implementations don't split across multiple processes.

The fix for bug 8746 added a hashtable instance that never actually
invoked HT_FIND.  This caused a warning, since we didn't mark HT_FIND

34f8723dc7 On Windows, terminate processes by handle, not pid
When we create a process yourself with CreateProcess, we get a
handle to the process in the PROCESS_INFO output structure.  But
instead of using that handle, we were manually looking up a _new_
handle based on the process ID, which is a poor idea, since the
process ID might refer to a new process later on, but the handle
can't.

f9f450d688 Also raise the check for 0 circuit ID in created cell.
And add a comment about why conditions that would cause us to drop a
cell should get checked before actions that would cause us to send a
destroy cell.

Spotted by 'cypherpunks'.

And note that these issues have been present since 0.0.8pre1 (commit
0da256ef), where we added a "shutting down" state, and started
responding to all create cells with DESTROY when shutting down.

6557e61295 Replace last_added_nonpadding with last_had_circuits
The point of the "idle timeout" for connections is to kill the
connection a while after it has no more circuits.  But using "last
added a non-padding cell" as a proxy for that is wrong, since if the
last circuit is closed from the other side of the connection, we
will not have sent anything on that connection since well before the
last circuit closed.

This is part of fixing 6799.

When applied to 0.2.5, it is also a fix for 12023.

463f6628d3 Give each or_connection_t a slightly randomized idle_timeout
Instead of killing an or_connection_t that has had no circuits for
the last 3 minutes, give every or_connection_t a randomized timeout,
so that an observer can't so easily infer from the connection close
time the time at which its last circuit closed.

Also, increase the base timeout for canonical connections from 3
minutes to 15 minutes.

Fix for ticket 6799.

cca6198c77 Avoid illegal read off end of an array in prune_v2_cipher_list
This function is supposed to construct a list of all the ciphers in
the "v2 link protocol cipher list" that are supported by Tor's
openssl.  It does this by invoking ssl23_get_cipher_by_char on each
two-byte ciphersuite ID to see which ones give a match.  But when
ssl23_get_cipher_by_char cannot find a match for a two-byte SSL3/TLS
ciphersuite ID, it checks to see whether it has a match for a
three-byte SSL2 ciphersuite ID.  This was causing a read off the end
of the 'cipherid' array.

This was probably harmless in practice, but we shouldn't be having
any uninitialized reads.

(Using ssl23_get_cipher_by_char in this way is a kludge, but then
again the entire existence of the v2 link protocol is kind of a
kludge.  Once Tor 0.2.2 clients are all gone, we can drop this code
entirely.)

Found by starlight. Fix on 0.2.4.8-alpha. Fixes bug 12227.
