dist is short for distribution. This is the new Go distribution tool.
The plan is to replace the Makefiles with what amounts to
'go tool dist bootstrap', although it cannot be invoked like
that since it is in charge of getting us to the point where we
can build the go command.
It will also add additional commands to replace bash scripts
like test/run (go tool dist testrun), eventually eliminating our
dependence on not just bash but all the Unix tools and all
of cygwin.
This is strong enough to build (cc *.c) and run (a.out bootstrap)
to build not just the C libraries and tools but also the basic
Go packages up to the bootstrap form of the go command
(go_bootstrap). I've run it successfully on both Linux and Windows.
This means that once we've switched to this tool in the build,
we can delete the buildscripts.
This tool is not nearly as nice as the go tool. There are many
special cases that turn into simple if statements or tables in
the code. Please forgive that. C does not enjoy the benefits
that we designed into Go.
I was planning to wait to do this until after Go 1, but the
Windows builders are both broken due to a bug in either
make or bash or both involving the parsing of quoted command
arguments. Make thinks it is invoking
quietgcc -fno-common -I"c:/go/include" -ggdb -O2 -c foo.c
but bash (quietgcc is a bash script) thinks it is being invoked as
quietgcc -fno-common '-Ic:/go/include -ggdb' -O2 -c foo.c
which obviously does not have the desired effect. Rather than fight
these clumsy ports, I accelerated the schedule for the new tool.
We should be completely off cygwin (using just the mingw gcc port,
which is much more standalone) before Go 1.
It is big for a single CL, and for that I apologize. I can cut it into
separate CLs along file boundaries if people would prefer that.

Added flag AllMethods: if not set (future default), embedded
methods of exported (and thus visible) embedded fields are not
shown in the final package documentation
The actual change for AllMethods is just in sortedFuncs. All
other changes are simplifications of the existing logic (mostly
deletion of code): Because method conflicts due to embedding
must always be detected, remove any premature elimination of
types and methods. Instead collect all named types and all
methods and do the filtering at the end.
Miscellaneous:
- renamed baseType -> namedType
- streamline logic for recording embedded types
- record embedded types via a map (simpler data structures)

The implementation is divided into 4 phases:
1) export filtering of an incoming AST if necessary (exports.go)
2) reading of a possibly filtered AST (reader.go: type reader)
3) method set computation (reader.go)
4) sorting and creation of final documentation (reader.go)
In contrast to the old implementation, the presentation data
(Names, Docs, Decls, etc.) are created immediately upon reading
the respective AST node. Also, all types are collected (embedded
or not) in a uniform way.
Once the entire AST has been processed, all methods and types
have been collected and the method sets for each type can be
computed (phase 3).

maps are sorted.

The bitLen function currently shifts out blocks of 8 bits at a time.
This change replaces this sorta-linear algorithm with a log(N)
one (shift out 16 bits, then 8, then 4, then 2, then 1).
I left the start of it linear at 16 bits at a time so that
the function continues to work with 32 or 64 bit values
without any funkiness.
The algorithm is similar to several of the nlz ("number of
leading zeros") algorithms from "Hacker's Delight" or the
"bit twiddling hacks" pages.
Doesn't make a big difference to the existing benchmarks, but
I'm using the code in a different context that calls bitLen
much more often, so it seemed worthwhile making the existing
codebase faster so that it's a better building block.

and handle cgo is too much work. Instead, we build
a stripped down version of the go tool, compiled as go_bootstrap,
that substitutes an error stub for the usual HTTP code.
The buildscript builds go_bootstrap, go_bootstrap builds
the standard packages and commands, including the full
including-HTTP-support go tool, and then go_bootstrap
gets deleted.
Also handle the case where the buildscript needs updating
during all.bash: if it fails but a go command can be found on
the current $PATH, try to regenerate it. This gracefully
handles situations like adding a new file to a package
used by the go tool.

This lets the client of go/build specify additional tags that
can be recognized in a // +build directive. For example,
a build for a custom environment like App Engine might
include "appengine" in the BuildTags list, so that packages
can be written with some files saying
// +build appengine (build only on app engine)
or
// +build !appengine (build only when NOT on app engine)
App Engine here is just a hypothetical context. I plan to use
this in the cmd/go sources to distinguish the bootstrap version
of cmd/go (which will not use networking) from the full version
using a custom tag. It might also be useful in App Engine.
Also, delete Build and Script, which we did not end up using for
cmd/go and which never got turned on for real in goinstall.

Marshalling of []byte in attributes and the general
marshalling of named []byte types was fixed.
A []byte field also won't be nil if an XML element
was mapped to it, even if the element is empty.
Tests were introduced to make sure that *struct{}
fields works correctly for element presence testing.
No changes to the logic made in that regard.

summary: gc: fix infinite recursion for embedded interfaces
This is causing 'interface type loop' errors during compilation
of a complex program. I don't understand what's happening
well enough to boil it down to a simple test case, but undoing
this change fixes the problem.
The change being undone is fixing a corner case (uses of
pointer to interface in an interface definition) that basically
only comes up in erroneous Go programs. Let's not try to
fix this again until after Go 1.
Unfixes issue 1909.

We already use GOHOSTOS to represent the host OS that the toolchain
will be run on, so no need to resort to uname(1) to get that (and
use uname(1) will make cross-compiling for another host impossible).

- do not use C.stat, since it is renamed to C._stat by mingw
- use fopen to implement TestErrno, since C.strtol

- skip TestSetEnv on windows, because os.Setenv
sets windows process environment, while C.getenv

This makes YCbCr match the other image types (e.g. RGBA, Gray) in
that an image's bounds is not restricted to the positive quadrant.
Also optimize the YCbCr draw code by hoisting some computation
outside of the loop.

Like https://golang.org/cl/4681044/ I don't think a gofix is
feasible. People will have to make manual changes. On the other hand,
directly manipulating YCbCr images is relatively rare, compared to
RGBA images, and if other code just uses the jpeg and draw packages
instead of messing directly with a YCbCr's []byte representations,
then things should just continue to work.

Remove NewMD5, NewSHA1 and NewSHA256 in favor of using New and
explicitly importing the used hash-function. This way when using, for
example, HMAC with RIPEMD there's no md5, sha1 and sha256 linked in
through the hmac package.
A gofix rule is included, and applied to the standard library (3 files
altered).
This change is the result of a discussion at
https://golang.org/cl/5550043/ to pull the discussion about
deprecating these functions out of that issue.

The previous version of all the node.String methods printed the parse
tree and was useful for developing the parse tree code. Now that that's done,
we might as well print the nodes using the standard template syntax.
It's much easier to read and makes error reporting look more natural.

(Sending to r because of the API change.)
This change alters the API for crypto/elliptic to permit different
implementations in the future. This will allow us to add faster,
constant-time implementations of the standard curves without any more
API changes.
As a demonstration, it also adds a constant-time implementation of
P224. Since it's only 32-bit, it's actually only about 40% the speed
of the generic code on a 64-bit system.

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation: a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart. This was confusing.
Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail. This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP
request.
