in the code snippet below which is inside a function, is "defer
resp.Body.Close() " in the appropriate position?
am i required to always do a resp.Body.Close()?
...
resp, err := client.Do(req)
log.Printf("resp: %+v\n", resp)
if resp.StatusCode != http.StatusOK {
return errors.NewHTTPErr
Defer defers the esecutiin of the following expression, but not the evaluation
of the arguments.
So "defer fn(a==1)" will call fn when this function exists, with a bool that is
true iff a _was_ 1 when the defer was registered.

thanks! seems to be working out for me too so far. makes me wonder what the
use cases might be for sql.NullXYZ and other similar types from non-stdlib
packages other than making the connection to db nulls more obvious maybe?

example :
fn := func() {
fmt.Println(10)
}
defer fn()
my question is why use defer fn() not defer fn
when we use fn() here doesn't it mean call it now ???

Hi Keith,
Can you share some specific things you’d like to see already implemented?
Serving JSON data and web pages to a browser seems like a straightforward
project with the standard library examples and resources available with
Internet search engines.

Untested here. I've seen it work on macOS with Safari, Chrome, and Firefox.
The || is to support how different browsers indicate a back button press /
back cache load.

Looks like something has gone wrong with the play.golang.org caching.

syscall.Stat_t does have the Dev field, which is documented by POSIX:
https://linux.die.net/man/2/stat: "The st_dev field describes the device on
which this file resides. (The major(3) and minor(3) macros may be useful to
decompose the device ID in this field.)"
In Go we don't have the major and m
Just to say that neugram.io has also a Jupyter front-end. Here's an example

A couple of comments.
This is probably obvious, but I wanted to point out that matthe...'s code
would require *all *access to the map to be synchronized using the mutex.
It's a simple and effective solution. One downside to his code is that it
holds the lock for the duration of the Copy(). Thi
It isn't something that is likely to be added to the stdlib. If anything, a
library like https://github.com/Logicalis/asn1 might be interested in
supporting it / accepting a pull request to add it.

I see the same thing. Changing even one character fixes the problem. Even
just adding white space to the code. If I copy the example from
https://golang.org/ to the playground exactly (
https://play.golang.org/p/-MKUWeDBml7 ) it also prints nothing.

Sure, that's possible. I will check and see how to implement it
properly.

Hi Jeeva,
Thanks for sharing go-resty here. I’d like to mention that my input about
struct embedding may not be valid. It was pointed out to me previously when
I made a similar suggestion that in library design embedding exports all of
the embedded type’s methods, so you may have those named fi
For me it works perfect when I just define each nullable field as a pointer in
the struct which represents a da base record. If the struct field is nil it
will be null in the database and json encoding handles these fields also
correctly

I'm having a problem building an ios framework that depends on a OpenGL
library.
if this is the file:
package gfx
import (
"github.com/goxjs/gl"
)
func test() {
gl.Clear(gl.COLOR_BUFFER_BIT)
}
This is the build output:
gomobile bind -target=ios
gomobile: go install
-pkgdir=/Users/johnt
What do you think about offering a second variant to allow passing in the
http server? It's possible one may want to set limits or other
configuration on the HTTP server instead of using the default http server.
