      sync: always wake up previously sleeping goroutines on Cond.Signal · 17bfa32f
      Gustavo Niemeyer authored 
      This changes the internal implementation of Cond so that
it uses two generations of waiters.  This enables Signal
to guarantee that it will only wake up waiters that are
currently sleeping at the call time.

Fixes #1648.

      exec: new API, replace Run with Command · f259f6ba
      Brad Fitzpatrick authored 
      This removes exec.Run and replaces exec.Cmd with a
new implementation. The new exec.Cmd represents
both a currently-running command and also a command
being prepared. It has a good zero value.

You can Start + Wait on a Cmd, or simply Run it.
Start (and Run) deal with copying stdout, stdin,
and stderr between the Cmd's io.Readers and
io.Writers.

There are convenience methods to capture a command's
stdout and/or stderr.

      big: ~8x faster number scanning · ce2701b2
      Robert Griesemer authored 
      - better number scanning algorithm
- fixed a couple of bugs related to base interpretation
- added scan benchmark
- added more test cases and made tests more precise
- introduced Int.scan method matching nat.scan
- refactored Int.Scan; now uses int.scan
- refactored Int.SetString; now uses int.scan

There is more potential, this was a fairly simple change.

gotest -test.bench="ScanPi" before/after (best of 3 runs):
big.BenchmarkScanPi	   1000	    2024900 ns/op
big.BenchmarkScanPi       10000      257540 ns/op

      undo CL 4557058 / b4c2ffae7034 · 16dbf218
      Russ Cox authored 
      Using the getaddrinfo order is only okay if we
are smart enough to try multiple addresses in Dial.
Since the code does not do that, we must make
the right first choice, regardless of what getaddrinfo
does, and more often that not that means using the
IPv4 address, even on IPv6 systems.  With the CL
applied, gotest fails in package net on OS X.

««« original CL description
net: name-based destination address selection

getaddrinfo() orders the addresses according to RFC 3484.

This means when IPv6 is working on a host we get results like:
    []string = {"2001:4810::110", "66.117.47.214"}

and when it's not working we get:
    []string = {"66.117.47.214", "2001:4810::110"}

thus can drop firstFavoriteAddr.

This also means /etc/gai.conf works on relevant systems.

      crypto/openpgp: add support for symmetrically encrypting files. · e0cca45f
      Adam Langley authored 
      This mostly adds the infrastructure for writing various forms of
packets as well as reading them. Adding symmetric encryption support
was simply an easy motivation.

There's also one brown-paper-bag fix in here. Previously I had the
conditional for the MDC hash check backwards: the code was checking
that the hash was *incorrect*. This was neatly counteracted by another
bug: it was hashing the ciphertext of the OCFB prefix, not the
plaintext.
