* Thread support is now requiredNick Mathewson2014-06-20
| | | | | | | | | | | 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.
* Remove code for Windows CE supportNick Mathewson2014-06-20
| | | | | | | As far as I know, nobody has used this in ages. It would be a pretty big surprise if it had worked. Closes ticket 11446.

| * Believe that v3 dirauths always serve extra infos.Karsten Loesing2014-05-05
| | | | | | | | | | | | | | | | Clients should always believe that v3 directory authorities serve extra-info documents, regardless of whether their server descriptor contains a "caches-extra-info" line or not. Fixes part of #11683.

* | Add ATTR_UNUSED to HT_FINDNick Mathewson2014-06-14
| | | | | | | | | | | | 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 as okay-not-to-use.

| * | More unit tests for process spawningNick Mathewson2014-06-14
| | | | | | | | | | | | | | | | | | Try killing a running process; try noticing that a process has exited without checking its output; verify that waitpid_cb (when present) is set to NULL when you would expect it to be.
| * | New testing-only tor_sleep_msec functionNick Mathewson2014-06-14
| | | | | | | | | | | | | | | In the unit tests I want to loop with a delay, but I want less than a 1 second delay. This, sadly, requires compatibility code.
| * | On Windows, terminate processes by handle, not pidNick Mathewson2014-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | Use waitpid code to learn when a controlled process diesNick Mathewson2014-06-14
| | | | | | | | | | | | | | | | | | This lets us avoid sending SIGTERM to something that has already died, since we realize it has already died, and is a fix for the unix version of #8746.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | | | Move circuit-id-in-use check for CREATE cells to before all other checksNick Mathewson2014-06-10
| |/ / / | | | | | | | | | | | | | | | | This means that we never send a DESTROY cell in response to an attempt to CREATE an existing circuit. Fixes bug 12191.

| * | | | Replace last_added_nonpadding with last_had_circuitsNick Mathewson2014-06-11

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.
| * | | | Give each or_connection_t a slightly randomized idle_timeoutNick Mathewson2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(It didn't remember any address you didn't tell it to remember) * It was AF_INET only. * It looked at its cache even if the sandbox wasn't turned on. * It couldn't remember errors. * It had some memory management problems. (You can't use memcpy to copy an addrinfo safely; it has pointers in.) This patch fixes those issues, and moves to a hash table. Fixes bug 11970; bugfix on 0.2.5.1-alpha.

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.
