      net/http: fix spurious logging in Transport when server closes idle conn · 4d2ac544
      Brad Fitzpatrick authored 
      In https://golang.org/3210, Transport errors occurring before
receiving response headers were wrapped in another error type to
indicate to the retry logic elsewhere that the request might be
re-tryable. But a check for err == io.EOF was missed, which then became
false once io.EOF was wrapped in the beforeRespHeaderError type.

The beforeRespHeaderError was too fragile. Remove it. I tried to fix
it in an earlier version of this CL and just broke different things
instead.

Also remove the "markBroken" method. It's redundant and confusing.

Also, rename the checkTransportResend method to shouldRetryRequest and
make it return a bool instead of an error. This also helps readability.

Now the code recognizes the two main reasons we'd want to retry a
request: because we never wrote the request in the first place (so:
count the number of bytes we've written), or because the server hung
up on us before we received response headers for an idempotent request.

As an added bonus, this could make POST requests safely re-tryable
since we know we haven't written anything yet. But it's too late in Go
1.7 to enable that, so we'll do that later (filed #15723).

This also adds a new internal (package http) test, since testing this
blackbox at higher levels in transport_test wasn't possible.

Fixes #15446

      crypto/x509: add Admin & User Keychains to FetchPEMRoots on Darwin · 6cd698d7
      Lee Hinman authored 
      in root_cgo_darwin.go only certificates from the System Domain
were being used in FetchPEMRoots.  This patch adds support for
getting certificates from all three domains (System, Admin,
User).  Also it will only read trusted certificates from those
Keychains.  Because it is possible to trust a non Root certificate,
this patch also adds a checks to see if the Subject and Issuer
name are the same.

      crypto/ecdsa: reject negative inputs. · b30fcbc9
      Adam Langley authored 
      The fact that crypto/ecdsa.Verify didn't reject negative inputs was a
mistake on my part: I had unsigned numbers on the brain. However, it
doesn't generally cause problems. (ModInverse results in zero, which
results in x being zero, which is rejected.)

The amd64 P-256 code will crash when given a large, negative input.

This fixes both crypto/ecdsa to reject these values and also the P-256
code to ignore the sign of inputs.

      vcs: Add support for git.openstack.org · 2ba8fc5b
      Monty Taylor authored 
      Go is being proposed as an officially supported language for elements of
OpenStack:

  https://review.openstack.org/#/c/312267/

As such, repos that exist in OpenStack's git infrastructure
are likely to become places from which people might want to go get
things. Allow optional .git suffixes to allow writing code that depends
on git.openstack.org repos that will work with older go versions while
we wait for this support to roll out.

      cmd/compile: reduce element size of arrays in sparse{map,set} · d35a4158
      David Chase authored 
      sparseSet and sparseMap only need 32 bit integers in their
arrays, since a sparseEntry key is also limited to 32 bits.
This appears to reduce the space allocated for at least
one pathological compilation by 1%, perhaps more.

Not necessarily for 1.7, but it saves a little and is very
low-risk.

      cmd/compile: handle unsafe.Pointer(f()) correctly · c65647d6
      Matthew Dempsky authored 
      Previously statements like

    f(unsafe.Pointer(g()), int(h()))

would be reordered into a sequence of statements like

    autotmp_g := g()
    autotmp_h := h()
    f(unsafe.Pointer(autotmp_g), int(autotmp_h))

which can leave g's temporary value on the stack as a uintptr, rather
than an unsafe.Pointer. Instead, recognize uintptr-to-unsafe.Pointer
conversions when reordering function calls to instead produce:

    autotmp_g := unsafe.Pointer(g())
    autotmp_h := h()
    f(autotmp_g, int(autotmp_h))

Fixes #15329.

      net/http: add test confirming a connection reuse case · f962e6e0
      Brad Fitzpatrick authored 
      Verify that for a server doing chunked encoding, with the final data
and EOF arriving together, the client will reuse the connection even
if it closes the body without seeing an EOF. The server sends at least
one non-zero chunk and one zero chunk. This verifies that the client's
bufio reading reads ahead and notes the EOF, so even if the JSON
decoder doesn't read the EOF itself, as long as somebody sees it, a
close won't forcible tear down the connection. This was true at least
of https://golang.org/cl/21291

No code change. Test already passed (even with lots of runs, including
in race mode with randomized goroutine scheduling).

      runtime: prevent racefini from being invoked more than once · 733162fd
      James Chacon authored 
      racefini calls __tsan_fini which is C code and at the end of it
invoked the standard C library exit(3) call. This has undefined
behavior if invoked more than once. Specifically in C++ programs
it caused static destructors to run twice. At least on glibc
impls it also means the at_exit handlers list (where those are
stored) also free's a list entry when it completes these. So invoking
twice results in a double free at exit which trips debug memory
allocation tracking.

Fix all of this by using an atomic as a boolean barrier around
calls to racefini being invoked > 1 time.

Fixes #15578
