I vote for 2.
The sql package is a bad example, as it existed before context, so it had to
duplicate itself for context.

I'm working on a client client API, and am accepting a `context.Context`
argument as the first argument to each function.
However, for ease of use, I'm also providing non-context aware versions of
each method. So my API looks roughly like:
FooContext(ctx context.Context, args...)

Many thanks to all of you, I suspected it was related to the copy made
while dereferencing the pointer but I didn't know that the runtime also
stores a copy of the pointer, It is not explicitly stated in the
documentation.

Hello,
I am working on a piece of code that imports "context". All the APIs
include (foobar context.Context) variable.
Another imported package expects "golang.org/x/net/context".Context as an

Hi,
I've been looking into why some of our code wasn't resulting in the memclr
optimization originally introduced in response
to https://github.com/golang/go/issues/5373. I'm still a bit unclear on why
this happens. Here is the code that triggers the issue for me:
package foo
import (

If I remember correctly, you can just go wild and put in all the
parenthesis you want and "go fmt" will clean it up for you wrt precedence
rules

Hi.
The AuthCodeURL function accepts the optional opts parameters.
However I can't find a reference to AuthCodeOption access_type and
approval_prompt in the the RFC 6749.
Where are they defined?
Thanks Manlio

Hi Fabián,
The reason that this isn't working is because time.Ticker contains a
runtimeTimer field:
r: runtimeTimer{
when: when(d),
period: int64(d),
f: sendTime,
arg:c,
},
This corresponds with a struct defined in runtime:
// Package time
When you dereference pointer, you creates a copy at different address. But
runtime internals stores pointer to original ticker, not your copy. So, call to
Stop on your copy simply does nothing. All created tickers are alive and still
sending ticks.

Don't do this:
t.ticker = *time.NewTicker(t.period)
Never, never, never dereference anything you got from standard library by
pointer. (And not only from standard library).

It is the -m flag that is generating the output you see.
If there is some other bug, please let us know what it is.

Your expression is (effectively) ((z*z-x)/2)*z. Use parentheses to group
the 2*z term: (z*z-x)/(2*z).

Hello,
Am a newbie to golang, and was trying myself with golang tour.
I was trying https://tour.golang.org/flowcontrol/8 and below is my code
snippet for the same
package main
import (
"fmt"
"math"
)
func Sqrt(x float64) float64 {
z := float64(1)
for i := 0; i < 10; i++ {
//z = z - (z*z-x
