There are also numerous internal improvements - to try to make the code easier for developers to work with. - - This is the first alpha release in a new series, so expect there to be - bugs. Users who would rather test out a more stable branch should - stay with 0.2.2.x for now. - - o Major features: - - Tor can now optionally build with the "bufferevents" buffered IO - backend provided by Libevent 2. To use this feature, make sure you - have the latest possible version of Libevent, and pass the - --enable-bufferevents flag to configure when building Tor from - source. This feature will make our networking code more flexible, - let us stack layers on each other, and let us use more efficient - zero-copy transports where available. - - As an experimental feature, Tor can use IOCP for networking on Windows. - Once this code is tuned and optimized, it promises much better - performance than the select-based backend we've used in the past. To - try this feature, you must build Tor with Libevent 2, configure Tor - with the "bufferevents" buffered IO backend, and add "DisableIOCP 0" to - your torrc. There are known bugs here: only try this if you can help - debug it as it breaks. - - The EntryNodes option can now include country codes like {de} or IP - addresses or network masks. Previously we had disallowed these options - because we didn't have an efficient way to keep the list up to - date. Fixes bug 1982, but see bug 2798 for an unresolved issue here. - - Exit nodes now accept and queue data on not-yet-connected streams. - Previously, the client wasn't allowed to send data until the stream was - connected, which slowed down all connections. This change will enable - clients to perform a "fast-start" on streams and send data without - having to wait for a confirmation that the stream has opened. (Patch - from Ian Goldberg; implements the server side of Proposal 174.) - - Tor now has initial support for automatic port mapping on the many - home routers that support NAT-PMP or UPnP. (Not yet supported on - Windows). To build the support code, you'll need to have libnatpnp - library and/or the libminiupnpc library, and you'll need to enable the - feature specifically by passing "--enable-upnp" and/or - "--enable-natpnp" to configure. To turn it on, use the new - PortForwarding option. - - Caches now download, cache, and serve multiple "flavors" of the - consensus, including a flavor that describes microdescriptors. - - Caches now download, cache, and serve microdescriptors -- small - summaries of router descriptors that are authenticated by all of the - directory authorities. Once enough caches are running this code, - clients will be able to save significant amounts of directory bandwidth - by downloading microdescriptors instead of router descriptors. - - o Minor features: - - Make logging resolution configurable with a new LogGranularity - option, and change the default from 1 millisecond to 1 - second. Implements enhancement 1668. - - We log which torrc file we're using on startup. Implements ticket - 2444. - - Ordinarily, Tor does not count traffic from private addresses (like - 127.0.0.1 or 10.0.0.1) when calculating rate limits or accounting. - There is now a new option, CountPrivateBandwidth, to disable this - behavior. Patch from Daniel Cagara. - - New --enable-static-tor configure option for building Tor as - statically as possible. Idea, general hackery and thoughts from - Alexei Czeskis, John Gilmore, Jacob Appelbaum. Implements ticket - 2702. - - If you set the NumCPUs option to 0, Tor will now try to detect how - many CPUs you have. This is the new default behavior. - - Turn on directory request statistics by default and include them in - extra-info descriptors. Don't break if we have no GeoIP database. - - Relays that set "ConnDirectionStatistics 1" write statistics on the - bidirectional use of connections to disk every 24 hours. - - Add a GeoIP file digest to the extra-info descriptor. Implements - enhancement 1883. - - Add a new 'Heartbeat' log message type to periodically log a message - describing Tor's status at level Notice. This feature is meant for - operators who log at notice, and want to make sure that their Tor - server is still working. Implementation by George Kadianakis. - - o Minor bugfixes (on 0.2.2.25-alpha): - - When loading the microdesc journal, remember its current size. - In 0.2.2, this helps prevent the microdesc journal from growing - without limit on authorities (who are the only ones to use it in - 0.2.2). Fixes a part of bug 2230; bugfix on 0.2.2.6-alpha. - Fix posted by "cypherpunks." - - The microdesc journal is supposed to get rebuilt only if it is - at least _half_ the length of the store, not _twice_ the length - of the store. Bugfix on 0.2.2.6-alpha; fixes part of bug 2230. - - If as an authority we fail to compute the identity digest of a v3 - legacy keypair, warn, and don't use a buffer-full of junk instead. - Bugfix on 0.2.1.1-alpha; fixes bug 3106. - - Authorities now clean their microdesc cache periodically and when - reading from disk initially, not only when adding new descriptors. - This prevents a bug where we could lose microdescriptors. Bugfix - on 0.2.2.6-alpha. - - o Minor features (controller): - - Add a new SIGNAL event to the controller interface so that - controllers can be notified when Tor handles a signal. Resolves - issue 1955. Patch by John Brooks. - - Add a new GETINFO option to get total bytes read and written. Patch - from pipe, revised by atagar. Resolves ticket 2345. - - Implement some GETINFO controller fields to provide information about - the Tor process's pid, euid, username, and resource limits. - - o Build changes: - - Our build system requires automake 1.6 or later to create the - Makefile.in files. Previously, you could have used 1.4. - This only affects developers and people building Tor from git; - people who build Tor from the source distribution without changing - the Makefile.am files should be fine. - - Our autogen.sh script uses autoreconf to launch autoconf, automake, and - so on. This is more robust against some of the failure modes - associated with running the autotools pieces on their own. - - o Minor packaging issues: - - On OpenSUSE, create the /var/run/tor directory on startup if it is not - already created. Patch from Andreas Stieger. Fixes bug 2573. - - o Code simplifications and refactoring: - - A major revision to our internal node-selecting and listing logic. - Tor already had at least two major ways to look at the question of - "which Tor servers do we know about": a list of router descriptors, - and a list of entries in the current consensus. With - microdescriptors, we're adding a third. Having so many systems - without an abstraction layer over them was hurting the codebase. - Now, we have a new "node_t" abstraction that presents a consistent - interface to a client's view of a Tor node, and holds (nearly) all - of the mutable state formerly in routerinfo_t and routerstatus_t. - - The helper programs tor-gencert, tor-resolve, and tor-checkkey - no longer link against Libevent: they never used it, but - our library structure used to force them to link it. - - o Removed features: - - Remove some old code to work around even older versions of Tor that - used forked processes to handle DNS requests. Such versions of Tor - are no longer in use as servers. - - o Documentation fixes: - - Correct a broken faq link in the INSTALL file. Fixes bug 2307. - - Add missing documentation for the authority-related torrc options - RephistTrackTime, BridgePassword, and V3AuthUseLegacyKey. Resolves - issue 2379. - - Changes in version 0.2.2.27-beta - 2011-05-18 Tor 0.2.2.27-beta fixes a bridge-related stability bug in the previous release, and also adds a few more general bugfixes. @@ -300,6 +156,150 @@ Changes in version 0.2.2.26-beta - 2011-05-17 bug 3022. +Changes in version 0.2.3.1-alpha - 2011-05-05 + Tor 0.2.3.1-alpha adds some new experimental features, including support + for an improved network IO backend, IOCP networking on Windows, + microdescriptor caching, "fast-start" support for streams, and automatic + home router configuration.
