This CL defines a new, more Go-like representation of
Go types (different structs for different types as
opposed to a single Type node). It also implements
an ast.Importer for object/archive files generated
by the gc compiler tool chain. Besides the individual
type structs, the main difference is the handling of
named types: In the old world, a named type had a
non-nil *Object pointer but otherwise looked no
different from other types. In this new model, named
types have their own representation types.Name. As
a result, resolving cycles is a bit simpler during
construction, at the cost of having to deal with
types.Name nodes explicitly later. It remains to be
seen if this is a good approach. Nevertheless, code
involving types reads more nicely and benefits from
full type checking. Also, the representation seems
to more closely match the spec wording.
Credits: The original version of the gc importer was
written by Evan Shaw (chickencha@gmail.com). The new
version in this CL is based largely on Evan's original
code but contains bug fixes, a few simplifications,
some restructuring, and was adjusted to use the
new type hierarchy. I have added a comprehensive test
that imports all packages found under $GOROOT/pkg (with
a 3s time-out to limit the run-time of the test). Run
gotest -v for details.
The original version of ExportData (exportdata.go) was
written by Russ Cox (rsc@golang.org). The current version
is returning the internal buffer positioned at the beginning
of the export data instead of printing the export data to
stdout.
With the new types package, the existing in-progress
typechecker package is deprecated. I will delete it
once all functionality has been brought over.

Right now if a Go developer makes a patch on one machine
and then clpatches it onto another machine, changes
subsequently made to the description are kept only
locally, under the assumption that you are running
clpatch because someone else wrote the CL, so you
don't have permission to update the web.
This change makes clpatch discard the "this was a
clpatch" information from the metadata when you
clpatch your own CLs from one machine to another.
This should eliminate some confusion (for example
in CL 4314054) but will no doubt introduce other
confusion.

Moved the details of how to read a directory
and how to parse the results behind the new
syscall functions ReadDirent and ParseDirent.
Now os needs just one copy of Readdirnames
for the three Unix variants, and it no longer
imports "unsafe".

- used to be only for standard log, not for user-built.
- there were no getters.
Also rearrange the code a little so we can avoid allocating
a buffer on every call. Logging is expensive but we should
avoid unnecessary cost.
This should have no effect on existing code.

Also, fix a print statement not to refer to make - it was a vestige of a prior form.

We replace the current Open with:
OpenFile(name, flag, perm) // same as old Open
Open(name) // same as old Open(name, O_RDONLY, 0)
Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
This CL includes a gofix module and full code updates: all.bash passes.
(There may be a few comments I missed.)
The interesting packages are:
gofix
os
Everything else is automatically generated except for hand tweaks to:

src/pkg/io/ioutil/tempfile.go
src/pkg/crypto/tls/generate_cert.go

Amazon S3 sends Transfer-Encoding "chunked"
on its 404 responses to HEAD requests for
missing objects.
We weren't ignoring the Transfer-Encoding
and were thus interpretting the subsequent
response headers as a chunk header from the
previous responses body (but a HEAD response
can't have a body)

A connection shouldn't be made available
for re-use until its body has been consumed.
(except in the case of pipelining, which isn't
implemented yet)
This CL fixes some issues seen with heavy load
against Amazon S3.
Subtle implementation detail: to prevent a race
with the client requesting a new connection
before previous one is returned, we actually
have to call putIdleConnection _before_ we
return from the final Read/Close call on the
http.Response.Body.
