muck with the 0.2.0.16-alpha some more

Changes in version 0.2.0.16-alpha - 2008-01-??

Changes in version 0.2.0.16-alpha - 2008-01-17

  o New directory authorities:

    - Set up gabelmoo (run by Karsten Loesing) as the fifth v3 directory

      authority.

  o Major performance improvements:

    - Switch our old ring buffer implementation for one more like that

      used by free Unix kernels.  The wasted space in a buffer with

      1mb of data will now be more like 8k than 1mb.  The new

      implementation also avoids realloc();realloc(); patterns that

      can contribute to memory fragmentation.

      memory fragmentation.

  o Minor features:

    - Configuration files now accept C-style strings as values. This

      helps encode characters not allowed in the current configuration

      file format, such as newline or #. Addresses bug 557.

    - Although we fixed bug 539 (where servers would send HTTP status 503

      responses _and_ send a body too), there are still servers out there

      that haven't upgraded.  Therefore, make clients parse such bodies

      when they receive them.

    - When we're not serving v2 directory information, there is no reason

      to actually keep any around.  Remove the obsolete files and directory

      on startup if they are very old and we aren't going to serve them.

  o Minor performance improvements:

    - Reference-count and share copies of address policy entries; only

      5% of them were actually distinct.

      of them were actually distinct.

    - Never walk through the list of logs if we know that no log is

      interested in a given message.

    - When an authority has not signed a consensus, do not try to

      download a nonexistent "certificate with key 00000000".  Bugfix

      on 0.2.0.x. Fixes bug 569.

    - Use a mutex to protect the list of logs, so we never write to

      the list as it's being freed.  Bugfix on 0.1.2.x.  Fixes the

      very rare bug 575, which is kind of the revenge of bug 222.

    - Fix a rare assert error when we're closing one of our threads:

    - Patch from Karsten Loesing to complain less at both the client

      and the relay when a relay used to have the HSDir flag but doesn't

      anymore, and we try to upload a hidden service descriptor.

    - Stop leaking one cert per TLS context.  Fixes bug 582.  Bugfix

      on 0.2.0.15-alpha.

    - Stop leaking one cert per TLS context. Fixes bug 582. Bugfix on

      0.2.0.15-alpha.

    - Do not try to download missing certificates until we have tried

      to check our fallback consensus. Fixes bug 583.

    - Make bridges round geoip info up, not down.

    - Make bridges round reported GeoIP stats info up to the nearest

      estimate, not down. Now we can distinguish between "0 people from

      this country" and "1 person from this country".

    - Avoid a spurious free on base64 failure. Bugfix on 0.1.2.

    - Detect more kinds of possible internal error.

    - Avoid possible segfault if key generation fails in

      crypto_pk_hybrid_encrypt. Bugfix on 0.2.0.

    - Avoid segfault in the case where a badly behaved v2 versioning

    - Fix possible bug in vote generation when server versions are present

      but client versions are not.

    - Fix rare bug on REDIRECTSTREAM control command when called with no

      port set: it could erroneously report an error when none had happened.

    - Avoid bogus crash-prone, leak-prone tor_realloc when we're compressing

      large objects and find ourselves with more than 4k left over.  Bugfix

      on 0.2.0.

      left over. Bugfix on 0.2.0.

    - Fix a small memory leak when setting up a hidden service.

    - Fix a few memory leaks that could in theory happen under bizarre error

      conditions.

    - Fix a few memory leaks that could in theory happen under bizarre

      error conditions.

    - Fix an assert if we post a general-purpose descriptor via the

      control port but that descriptor isn't mentioned in our current

      network consensus. Bug reported by Jon McLachlan; bugfix on

      0.2.0.9-alpha.

  o Minor features (controller):

    - Get NS events working again.  (Patch from tup)

    - Get NS events working again. Patch from tup.

    - The GETCONF command now escapes and quotes configuration values

      that don't otherwise fit into the torrc file.

    - The SETCONF command now handles quoted values correctly.

  o Minor features (directory authorities):

    - New configuration options to override default maximum number of

      servers allowed on a single IP address.  This is important

      for running a test network on a single host.

      running a test network on a single host.

    - Actually implement the -s option to tor-gencert.

    - Add a manual page for tor-gencert.

  o Minor features (bridges):

    - Bridge authorities no longer serve bridge descriptors over unencrypted

      connections.

    - Bridge authorities no longer serve bridge descriptors over

      unencrypted connections.

  o Minor features (other):

    - Add hidden services and DNSPorts to the list of things that make

      Tor accept that it has running ports.  Change starting Tor with

      no ports from a fatal error to a warning; we might change it

      back if this turns out to confuse anybody.  (Fixes bug 579.)
