SEC-1 says: “The component privateKey is the private key defined to be
the octet string of length ⌊log₂(n)/8⌋ (where n is the order of the
curve)”.
Previously the code for parsing ECC private keys would panic (on
non-amd64) when the private was too long. It would also pass a too-short
private key to crypto/elliptic, possibly resulting in undesirable
behaviour.
This change makes the parsing function handle both too much and too
little padding because GnuTLS does the former and OpenSSL did the latter
until 30cd4ff294252c4b6a4b69cbef6a5b4117705d22. It also causes
serialisation to pad private keys correctly.

parseBase128Int compares |shifted| with four, seemingly to ensure the result
fits in an int32 on 32-bit platforms where int is 32-bit. However, there is an
off-by-one in this logic, so it actually allows five shifts, making the maximum
tag number or OID component 2^35-1.
Fix this so the maximum is 2^28-1 which should be plenty for OID components and
tag numbers while not overflowing on 32-bit platforms.

In the beginning, there was no way to cancel an HTTP request.
We later added Transport.CancelRequest to cancel an in-flight HTTP
request by breaking its underlying TCP connection, but it was hard to
use correctly and didn't work in all cases. And its error messages
were terrible. Some of those issues were fixed over time, but the most
unfixable problem was that it didn't compose well. All RoundTripper
implementations had to choose to whether to implement CancelRequest
and both decisions had negative consequences.
In Go 1.5 we added Request.Cancel, which composed well, worked in all
phases, had nice error messages, etc. But we forgot to use it in the
implementation of Client.Timeout (a timeout which spans multiple
requests and reading request bodies).
In Go 1.6 (upcoming), we added HTTP/2 support, but now Client.Timeout
didn't work because the http2.Transport didn't have a CancelRequest
method.
Rather than add a CancelRequest method to http2, officially deprecate
it and update the only caller (Client, for Client.Cancel) to use
Request.Cancel instead.
The http2 Client timeout tests are enabled now.
For compatibility, we still use CancelRequest in Client if we don't
recognize the RoundTripper type. But documentation has been updated to
tell people that CancelRequest is deprecated.

In debugging the flaky test in #13825, I discovered that my previous
change to tighten and simplify the communication protocol between
Transport.roundTrip and persistConn.readLoop in
https://golang.org/cl/17890 wasn't complete.
This change simplifies it further: the buffered-vs-unbuffered
complexity goes away, and we no longer need to re-try channel reads in
the select case. It was trying to prioritize channels in the case that
two were readable in the select. (it was only failing in the race builder
because the race builds randomize select scheduling)
The problem was that in the bodyless response case we had to return
the idle connection before replying to roundTrip. But putIdleConn
previously both added it to the free list (which we wanted), but also
closed the connection, which made the caller goroutine
(Transport.roundTrip) have two readable cases: pc.closech, and the
response. We guarded against similar conditions in the caller's select
for two readable channels, but such a fix wasn't possible here, and would
be overly complicated.
Instead, switch to unbuffered channels. The unbuffered channels were only
to prevent goroutine leaks, so address that differently: add a "callerGone"
channel closed by the caller on exit, and select on that during any unbuffered
sends.
As part of the fix, split putIdleConn into two halves: a part that
just returns to the freelist, and a part that also closes. Update the
four callers to the variants each wanted.
Incidentally, the connections were closing on return to the pool due
to MaxIdleConnsPerHost (somewhat related: #13801), but this bug
could've manifested for plenty of other reasons.

This test triggers a large number of usleep(100)s. linux/arm, openbsd,

usleep(100) actually gives up the whole scheduling quantum. On Linux

generated when a process completes a whole scheduling quantum, so this
test often gets zero profiling signals and fails.
Until we figure out what to do about this, skip this test on these

The CloseNotifier implementation and documentation was
substantially changed in https://golang.org/cl/17750 but it was a bit
too aggressive.
Issue #13666 highlighted that in addition to breaking external
projects, even the standard library (httputil.ReverseProxy) didn't
obey the new rules about not using CloseNotifier until the
Request.Body is fully consumed.
So, instead of fixing httputil.ReverseProxy, dial back the rules a
bit. It's now okay to call CloseNotify before consuming the request
body. The docs now say CloseNotifier may wait to fire before the
request body is fully consumed, but doesn't say that the behavior is
undefined anymore. Instead, we just wait until the request body is
consumed and start watching for EOF from the client then.
This CL also adds a test to ReverseProxy (using a POST request) that
would've caught this earlier.

This CL changes the source file information in the

The linker then substitutes the actual $GOROOT (or $GOROOT_FINAL)
as appropriate.
If people download a binary distribution to an alternate location,
following the instructions at https://golang.org/doc/install#install,
the code before this CL would end up with source paths pointing to
/usr/local/go no matter where the actual sources were.
Now the source paths for built binaries will point to the actual sources
(hopefully).
The source line information in distributed binaries is not affected:
those will still say /usr/local/go. But binaries people build themselves
(their own programs, not the go distribution programs) will be correct.
Fixing this path also fixes the lookup of the runtime-gdb.py file.
