      cmd/compile: fix recorded export data position info · 2123a6c6
      Robert Griesemer authored 
      The position information recorded now consists of the line-
directive relative filename and line number. It would be
relatively easy to also encode absolute position information
as necessary (by serializing src.PosBase data).

For example, given $GOROOT/src/tmp/x.go:

	package p

	const C0 = 0

	//line c.go:10
	const C1 = 1

	//line t.go:20
	type T int

	//line v.go:30
	var V T

	//line f.go:40
	func F() {}

The recorded positions for the exported entities are:

	C0 $GOROOT/src/tmp/x.go 3
	C1 c.go 10
	T t.go 20
	V v.go 30
	F f.go 40

Fix verified by manual inspection. There's currently no easy way
to test this, but it will eventually be tested when we fix #7311.

Fixes #19391.

      database/sql: proper prepared statement support in transactions · 82e1732f
      Sarah Adams authored 
      This change was originally written by Marko Tiikkaja <marko@joh.to>.
https://go-review.googlesource.com/#/c/2035/

Previously *Tx.Stmt always prepared a new statement, even if an
existing one was available on the connection the transaction was on.
Now we first see if the statement is already available on the
connection and only prepare if it isn't. Additionally, when we do
need to prepare one, we store it in the parent *Stmt to allow it to be
later reused by other calls to *Tx.Stmt on that statement or just
straight up by *Stmt.Exec et al.

To make sure that the statement doesn't disappear unexpectedly, we
record a dependency from the statement returned by *Tx.Stmt to the
*Stmt it came from and set a new field, parentStmt, to point to the
originating *Stmt. When the transaction's *Stmt is closed, we remove
the dependency. This way the "parent" *Stmt can be closed by the user
without her having to know whether any transactions are still using it
or not.

Fixes #15606

      net/http: use httptest.Server Client in tests · 3b988eb6
      Johan Brandhorst authored 
      After merging https://go-review.googlesource.com/c/34639/,
it was pointed out to me that a lot of tests under net/http
could use the new functionality to simplify and unify testing.

Using the httptest.Server provided Client removes the need to
call CloseIdleConnections() on all Transports created, as it
is automatically called on the Transport associated with the
client when Server.Close() is called.

Change the transport used by the non-TLS
httptest.Server to a new *http.Transport rather than using
http.DefaultTransport implicitly. The TLS version already
used its own *http.Transport. This change is to prevent
concurrency problems with using DefaultTransport implicitly
across several httptest.Server's.

Add tests to ensure the httptest.Server.Client().Transport
RoundTripper interface is implemented by a *http.Transport,
as is now assumed across large parts of net/http tests.

      runtime/pprof: add GNU build IDs to Mappings recorded from /proc/self/maps · c797256a
      Russ Cox authored 
      This helps systems that maintain an external database mapping
build ID to symbol information for the given binary, especially
in the case where /proc/self/maps lists many different files
(for example, many shared libraries).

Avoid importing debug/elf to avoid dragging in that whole
package (and its dependencies like debug/dwarf) into the
build of every program that generates a profile.

Fixes #19431.
