I added the clientChan's msg channel to the list of channels that are closed in mainloop when the server sends a channelCloseMsg.
I added an ExitError type that wraps a Waitmsg similar to that of os/exec. I fill ExitStatus with the data returned in the 'exit-status' channel message and Msg with the data returned in the 'exit-signal' channel message.
Instead of having Wait() return on the first 'exit-status'/'exit-signal' I have it return an ExitError containing the status and signal when the clientChan's msg channel is closed.
I added two tests cases to session_test.go that test for exit status 0 (in which case Wait() returns nil) and exit status 1 (in which case Wait() returns an ExitError with ExitStatus 1)

This is part one of a small set of CL's that aim to resolve
the outstanding TODOs relating to channel close and blocking
behavior.
Firstly, the hairy handling of assigning the peersId is now
done in one place. The cost of this change is the slightly
paradoxical construction of the partially created clientChan.
Secondly, by creating clientChan.stdin/out/err when the channel
is opened, the creation of consumers like tcpchan and Session
is simplified; they just have to wire themselves up to the
relevant readers/writers.

This is a slight change to fmt's semantics, but means that if you use
%d to print an integer with a Stringable value, it will print as an integer.
This came up because Time.Month() couldn't cleanly print as an integer

should be no effect outside the fmt tests.
As a mild bonus, certain recursive failures of String methods
will also be avoided this way.

The SSH spec allows for the server to send a banner message to the client at any point during the authentication process. Currently the ssh client auth types all assume that the first response from the server after issuing a userAuthRequestMsg will be one of a couple of possible authentication success/failure messages. This means that client authentication breaks if the ssh server being connected to has a banner message configured.

According to http://www.ietf.org/rfc/rfc4254.txt most channel messages contain the channel id of the recipient channel, not the sender id. This allows the recipient connection multiplexer to route the message to the correct channel.
This changeset fixes several messages that incorrectly send the local channel id instead of the remote channel's id.
While sessions were being created and closed in sequence channels in the channel pool were freed and reused on the server side of the connection at the same rate as was done on the client, so the channel local and remote channel ids always corresponded. As soon as I had concurrent sessions on the same clientConn the server started to complain of 'uknown channel id N' where N is the local channel id, which is actually paired with server channel id K.

In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,

Currently, the state transition functions in the HTML parser
return the next insertion mode and whether the token is consumed.
This works well except for when one insertion mode needs to use
the rules for another insertion mode. Then the useTheRulesFor
function needs to patch things up. This requires comparing functions
for equality, which is going to stop working.
Adding a field to the parser structure to store the current
insertion mode eliminates the need for useTheRulesFor;
one insertion mode function can now just call the other
directly. The insertion mode will be changed only if it needs to be.

traditional /selinux. Check both locations for the selinux
filesystem in make.bash

I had to replace the single use of io/ioutil
in the time package with a bytes.Buffer since
there would've been a dependency cycle.
There are no other uses of os.Time.

It was never really a shell, but the name carried
over from SSH's ServerShell.
Two small functional changes:
Add SetSize, which allows the size of the terminal
to be changed in response, say, to an SSH message.
Don't write the prompt if there's already something
on the current line.

Godefs was a C program that ran gcc and then parsed the
stabs debugging information in the resulting object file to
generate C or Go code for bootstrapping as part of
package runtime or package syscall.
Cgo does the same work, but using the dwarf debugging
information. Add -godefs and -cdefs options to cgo that
mimic godefs's output, albeit with different input
(a Go program, not a C program).
This has been a "nice to have" for a while but was forced
by Apple removing stabs debugging output from their
latest compilers.
Fixes#835.
Fixes#2338.

This looks like it is just moving some code from
time to runtime (and translating it to C), but the
runtime can do a better job managing the goroutines,
and it needs this functionality for its own maintenance
(for example, for the garbage collector to hand back
unused memory to the OS on a time delay).
Might as well have just one copy of the timer logic,
and runtime can't depend on time, so vice versa.
It also unifies Sleep, NewTicker, and NewTimer behind
one mechanism, so that there are no claims that one
is more efficient than another. (For example, today
people recommend using time.After instead of time.Sleep
to avoid blocking an OS thread.)

Also make it agree with the documentation. You get an error, unless you're
calling Add explicitly, in which case it panics since that's almost certainly
a bug. The discrepancy was caused by a panic that wasn't turned into
an error along one path; deleted the offending function for clarity.
