Previously we checked the certificate chain from the leaf
upwards and expected to jump from the last cert in the chain to
a root certificate.
Although technically correct, there are a number of sites with
problems including out-of-order certs, superfluous certs and
missing certs.
The last of these requires AIA chasing, which is a lot of
complexity. However, we can address the more common cases by
using a pool building algorithm, as browsers do.
We build a pool of root certificates and a pool from the
server's chain. We then try to build a path to a root
certificate, using either of these pools.
This differs from the behaviour of, say, Firefox in that Firefox
will accumulate intermedite certificate in a persistent pool in
the hope that it can use them to fill in gaps in future chains.
We don't do that because it leads to confusing errors which only
occur based on the order to sites visited.
This change also enabled SNI for tls.Dial so that sites will return
the correct certificate chain.

The implemetation describes each value as a string identifying the
concrete type of the value, followed by the usual encoding of that
value. All types to be exchanged as contents of interface values
must be registered ahead of time with the new Register function.
Although this would not seem strictly necessary, the linker garbage
collects unused types so without some mechanism to guarantee
the type exists in the binary, there could be unpleasant surprises.
Moreover, the receiver needs a reflect.Type of the value to be
written in order to be able to save the data. A Register function
seems necessary.
The implementation may require defining types in the middle of
of sending a value. The old code never did this. Therefore there
has been some refactoring to make the encoder and decoder
work recursively.
This change changes the internal type IDs. Existing gob archives
will break with this change. Apologies for that. If this is a deal
breaker it should be possible to create a conversion tool.

Giving them specific types has the benefit that
binary.BigEndian.Uint32(b) is now a direct call, not an
indirect via a mutable interface value, so it can potentially
be inlined.
Recent changes to the spec relaxed the rules for comparison,
so this code is still valid:
func isLittle(o binary.ByteOrder) { return o == binary.LittleEndian }
The change does break this potential idiom:
o := binary.BigEndian
if foo {
o = binary.LittleEndian
}
That must rewrite to give o an explicit binary.ByteOrder type.
On balance I think the benefit from the direct call and inlining
outweigh the cost of breaking that idiom.

That is, move the pc/ln table and the symbol table
into the read-only data segment. This eliminates
the need for a special load command to map the
symbol table into memory, which makes the
information available on systems that couldn't handle
the magic load to 0x99000000, like NaCl and ARM QEMU
and Linux without config_highmem=y. It also
eliminates an #ifdef and some clumsy code to
find the symbol table on Windows.
The bad news is that the binary appears to be bigger
than it used to be. This is not actually the case, though:
the same amount of data is being mapped into memory
as before, and the tables are still read-only, so they're
still shared across multiple instances of the binary as
they were before. The difference is just that the tables
aren't squirreled away in some section that "size" doesn't
know to look at.
This is a checkpoint.
It probably breaks Windows and breaks NaCl more

New logging interface simplifies and generalizes.
1) Loggers now have only one output.
2) log.Stdout, Stderr, Crash and friends are gone.
Logging is now always to standard error by default.
3) log.Panic* replaces log.Crash*.
4) Exiting and panicking are not part of the logger's state; instead
the functions Exit* and Panic* simply call Exit or panic after
printing.
5) There is now one 'standard logger'. Instead of calling Stderr,
use Print etc. There are now triples, by analogy with fmt:
Print, Println, Printf
What was log.Stderr is now best represented by log.Println,
since there are now separate Print and Println functions
(and methods).
6) New functions SetOutput, SetFlags, and SetPrefix allow global
editing of the standard logger's properties. This is new
functionality. For instance, one can call
log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds)
to get all logging output to show file name, line number, and
time stamp.
In short, for most purposes
log.Stderr -> log.Println or log.Print
log.Stderrf -> log.Printf
log.Crash -> log.Panicln or log.Panic
log.Crashf -> log.Panicf
log.Exit -> log.Exitln or log.Exit
log.Exitf -> log.Exitf (no change)
This has a slight breakage: since loggers now write only to one
output, existing calls to log.New() need to delete the second argument.
Also, custom loggers with exit or panic properties will need to be
reworked.

On Linux, overwriting an mmap'ed file causes
all the MAP_PRIVATE pages to get refreshed
with the new content, even ones that have been
modified by the process that did the mmap.
One specific instance of this is that after the
dynamic linker has relocated a page from a .so,
overwriting the .so will un-relocate it, making
the next use of one of the no-longer-relocated
addresses incorrect and probably crash the
program.
Linux must go out of its way to break programs
in this way: the pages have already been copied
on write, so they're not shared with the file system
cache, and it trashes them anyway. The manual

up to several megabytes as long as it doesn't contain very long
contiguous sequences of equal bytes. For instance, index creation for

The key/value format of X.500 names means that it's possible to encode
a name with multiple values for, say, organisation. RFC5280
doesn't seem to consider this, but there are Verisign root
certificates which do this and, in order to find the correct
root certificate in some cases, we need to handle it.
Also, CA certificates should set the CA flag and we now check
this. After looking at the other X.509 extensions it appears
that they are universally ignored/bit rotted away so we ignore
them.

The decoder was crashing when handling an rpc that expected
a struct but was delivered something else. This diagnoses the
problem. The other direction (expecting non-struct but getting
one) was already handled.

The new comparison rule was added to the spec by
changeset: 5605:33abb649cb63
user: Robert Griesemer <gri@golang.org>
date: Thu Jun 03 16:55:50 2010 -0700
files: doc/go_spec.html
description:
go spec: Base comparison compatibility on assignment compatibility.
Specifically:
- Simplified definition of comparison compatibility and folded into
section on comparison operators since it's only used there.
This is a small language change/cleanup. As a consequence:
- An interface value may now be compared against a non-interface value.
- Channels with opposite directions cannot be compared directly anymore
(per discussion with rsc).

If you look at the sequence of values returned
by waitpid, it simply tells us about the child of
clone before it tells us that the parent called clone.
There's nothing we can do but assume unexpected
tids are newly cloned children.

1) hack regalloc to leave R9 (m) and R10 (g) alone.
the real fix is tricker, but this gets us running
2) fix up the few places in the package sources that
the shortage of registers affects, by simplifying
some expressions.
all of this should be reverted when the right fix is in.

Use OS rather than compiler specific flag the same way that
__FreeBSD__, __APPLE__, __OpenBSD__, and __linux__ are used.
_WIN32 is defined by GCC (and others) on windows for Win32
and Win64 applications. _WIN32 is set by default for several
other windows based compilers: DMC, MSVC, Intel, Watcom, LCC.
Although the change is for consistency, it allows the Go tools
to be compiled with non-Mingw GCC distributions and non-GCC
compilers that support the GCC extensions.

Old code was using recursion to traverse object graph.
New code uses an explicit stack, cutting the per-pointer
footprint to two words during the recursion and avoiding
the standard allocator and stack splitting code.
in test/garbage:
Reduces parser runtime by 2-3%
Reduces Peano runtime by 40%
Increases tree runtime by 4-5%

Also add exporter.Drain() to wait for completion.
This makes it possible for an Exporter to fire off a message
and wait (by calling Drain) for the message to be received,
even if a client has yet to call to retrieve it.
Once this design is settled, I'll do the same for import send.
Testing strategies welcome. I have some working stand-alone
tests.
