Issue #8633 (and #9134) noted that we didn't document the rules about
closing the Response.Body when Client.Do returned both a non-nil
*Response and a non-nil error (which can only happen when the user's
CheckRedirect returns an error).
In the process of investigating, I cleaned this code up a bunch, but
no user-visible behavior should have changed, except perhaps some
better error messages in some cases.
It turns out it's always been the case that when a CheckRedirect error
occurs, the Response.Body is already closed. Document that.
And the new code makes that more obvious too.

The change in 20907 fixed varexpr but broke aliased. After that change,
a reference to a field in a struct would not be seen as aliasing itself.
Before that change, it would, but only because all fields in a struct
aliased everything.
This CL changes the compiler to consider all references to a field as
aliasing all other fields in that struct. This is imperfect--a
reference to one field does not alias another field--but is a simple fix
for the immediate problem. A better fix would require tracking the
specific fields as well.
Fixes#15042.

Rather than checking the block final bit on the next invocation
of nextBlock, we check it at the termination of the current block.
This ensures that we return (n, io.EOF) instead of (0, io.EOF)
more frequently for most streams.
However, there are certain situations where an eager io.EOF is not done:
1) We previously returned from Read because the write buffer of the internal
dictionary was full, and it just so happens that there is no more data
remaining in the stream.
2) There exists a [non-final, empty, raw block] after all blocks that
actually contain uncompressed data. We cannot return io.EOF eagerly here
since it would break flushing semantics.
Both situations happen infrequently, but it is still important to note that
this change does *not* guarantee that flate will *always* return (n, io.EOF).
Furthermore, this CL makes no changes to the pattern of ReadByte calls
to the underlying io.ByteReader.
Below is the motivation for this change, pulling the text from
@bradfitz's CL/21290:
net/http and other things work better when io.Reader implementations
return (n, io.EOF) at the end, instead of (n, nil) followed by (0,
io.EOF). Both are legal, but the standard library has been moving
towards n+io.EOF.
An investigation of net/http connection re-use in
https://github.com/google/go-github/pull/317 revealed that with gzip
compression + http/1.1 chunking, the net/http package was not
automatically reusing the underlying TCP connections when the final
EOF bytes were already read off the wire. The net/http package only
reuses the connection if the underlying Readers (many of them nested
in this case) all eagerly return io.EOF.
Previous related CLs:
https://golang.org/cl/76400046 - tls.Reader
https://golang.org/cl/58240043 - http chunked reader
In addition to net/http, this behavior also helps things like

Compound AUTO types weren't named previously. That was because live
variable analysis (plive.go) doesn't handle spilling to compound types.
It can't handle them because there is no valid place to put VARDEFs when
regalloc is spilling compound types.
compound types = multiword builtin types: complex, string, slice, and
interface.
Instead, we split named AUTOs into individual one-word variables. For
example, a string s gets split into a byte ptr s.ptr and an integer
s.len. Those two variables can be spilled to / restored from
independently. As a result, live variable analysis can handle them
because they are one-word objects.
This CL will change how AUTOs are described in DWARF information.
Consider the code:
func f(s string, i int) int {
x := s[i:i+5]
g()
return lookup(x)
}
The old compiler would spill x to two consecutive slots on the stack,
both named x (at offsets 0 and 8). The new compiler spills the pointer
of x to a slot named x.ptr. It doesn't spill x.len at all, as it is a
constant (5) and can be rematerialized for the call to lookup.
So compound objects may not be spilled in their entirety, and even if
they are they won't necessarily be contiguous. Such is the price of
optimization.
Re-enable live variable analysis tests. One test remains disabled, it
fails because of #14904.

The http2 spec defines a magic string which initates an http2 session:
"PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n"
It was intentionally chosen to kinda look like an HTTP request, but
just different enough to break things not ready for it. This change
makes Go ready for it.
Notably: Go now accepts the request header (the prefix "PRI *
HTTP/2.0\r\n\r\n") as a valid request, even though it doesn't have a
Host header. But we now mark it as "Connection: close" and teach the
Server to never read a second request from the connection once that's
seen. If the http.Handler wants to deal with the upgrade, it has to
hijack the request, read out the "body", compare it against
"SM\r\n\r\n", and then speak http2. One of the new tests demonstrates
that hijacking.

As I said on that issue:
----
This is a progressive JPEG image. There are two dimensions of
progressivity: spectral selection (variables zs and ze in scan.go,
ranging in [0, 63]) and successive approximation (variables ah and al in
scan.go, ranging in [0, 8), from LSB to MSB, although ah=0 implicitly
means ah=8).
For this particular image, there are three components, and the SOS
markers contain this progression:
zs, ze, ah, al: 0 0 0 0 components: 0, 1, 2
zs, ze, ah, al: 1 63 0 0 components: 1
zs, ze, ah, al: 1 63 0 0 components: 2
zs, ze, ah, al: 1 63 0 2 components: 0
zs, ze, ah, al: 1 10 2 1 components: 0
zs, ze, ah, al: 11 63 2 1 components: 0
zs, ze, ah, al: 1 10 1 0 components: 0
The combination of all of these is complete (i.e. spectra 0 to 63 and
bits 8 exclusive to 0) for components 1 and 2, but it is incomplete for
component 0 (the luma component). In particular, there is no data for
component 0, spectra 11 to 63 and bits 1 exclusive to 0.
The image/jpeg code, as of Go 1.6, waits until both dimensions are
complete before performing the de-quantization, IDCT and copy to an
*image.YCbCr. This is the "if zigEnd != blockSize-1 || al != 0 { ...
continue }" code and associated commentary in scan.go.
Almost all progressive JPEG images end up complete in both dimensions
for all components, but this particular image is incomplete for
component 0, so the Go code never writes anything to the Y values of the
resultant *image.YCbCr, which is why the broken output is so dark (but
still looks recognizable in terms of red and blue hues).
My reading of the ITU T.81 JPEG specification (Annex G) doesn't
explicitly say that this is a valid image, but it also doesn't rule it
out.
In any case, the fix is, for progressive JPEG images, to always
reconstruct the decoded blocks (by performing the de-quantization, IDCT
and copy to an *image.YCbCr), regardless of whether or not they end up
complete. Note that, in Go, the jpeg.Decode function does not return
until the entire image is decoded, so we still only want to reconstruct
each block once, not once per SOS (Start Of Scan) marker.
----
A test image was also added, based on video-001.progressive.jpeg. When
decoding that image, inserting a
println("nComp, zs, ze, ah, al:", nComp, zigStart, zigEnd, ah, al)
into decoder.processSOS in scan.go prints:
nComp, zs, ze, ah, al: 3 0 0 0 1
nComp, zs, ze, ah, al: 1 1 5 0 2
nComp, zs, ze, ah, al: 1 1 63 0 1
nComp, zs, ze, ah, al: 1 1 63 0 1
nComp, zs, ze, ah, al: 1 6 63 0 2
nComp, zs, ze, ah, al: 1 1 63 2 1
nComp, zs, ze, ah, al: 3 0 0 1 0
nComp, zs, ze, ah, al: 1 1 63 1 0
nComp, zs, ze, ah, al: 1 1 63 1 0
nComp, zs, ze, ah, al: 1 1 63 1 0
In other words, video-001.progressive.jpeg contains 10 different scans.
This little program below drops half of them (remembering to keep the
"\xff\xd9" End of Image marker):
----
package main
import (
"bytes"
"io/ioutil"
"log"
)
func main() {
sos := []byte{0xff, 0xda}
eoi := []byte{0xff, 0xd9}
src, err := ioutil.ReadFile("video-001.progressive.jpeg")
if err != nil {
log.Fatal(err)
}
b := bytes.Split(src, sos)
println(len(b)) // Prints 11.
dst := bytes.Join(b[:5], sos)
dst = append(dst, eoi...)
if err := ioutil.WriteFile("video-001.progressive.truncated.jpeg", dst, 0666); err != nil {
log.Fatal(err)
}
}
----

Apparently I’m having a hard time following my
own naming scheme.

This removes almost all direct access to
Type’s heavily overloaded Type field.
Mostly generated by eg, manually checked.
Significant manual changes:
* reflect.go's typPkg used Type indiscriminately.
Use it only for specific etypes.
* gen.go's visitComponents contained a usage of Type
with structs. Using Type for structs no longer
occurs, and the Fatal contained therein has not triggered,
so it has been axed.
* Scary code in cgen.go's cgen_slice is now explicitly scary.
Passes toolstash -cmp.

Also, add two uses of Key and Val that I missed earlier.
As before, direct writes to Down and Type remain in bimport.

Partial revert of https://golang.org/cl/20967 which
I can't reproduce and actually breaks me more.

Previously, t.IsPtr() reported whether t was represented with a
pointer, but some of its callers expected it to report whether t is an
actual Go pointer. Resolve this by renaming t.IsPtr to t.IsPtrShaped
and adding a new t.IsPtr method to report Go pointer types.
Updated a couple callers in gc/ssa.go to use IsPtr instead of
IsPtrShaped.
Passes toolstash -cmp.
Updates #15028.
