Sorry, ignore that. In [1], I make a copy of a locked mutex, which creates
a *new *locked mutex.
Basically the only non-obvious behavior here is that `&(*m) == m` by the
rules of Go, the rest was explained above.

Answers above don't explain the difference in behavior:
[1] https://play.golang.org/p/lXA2F4b880W
[2] https://play.golang.org/p/doruBxrquhw
Why did deadlock happen in [1], despite creating a variable?
If I change the order ([2]), I do avoid a deadlock (meaning that I have two
separate mutexes).
Hi!
I have a little, low-traffic web app which connects to postgres 10 using
the pgx library (https://pkg.go.dev/github.com/jackc/pgx), and the database
connection gets closed causing 500 server error to be returned. I'm pretty
sure this is related to the db server being rebooted after updates
A truly fantastic package idea! Thanks a lot for sharing it.
I just wish it would be cut a little bit differently.
1 module for the formats using only the stdlib
1 module each for sqlite and excel support.
That woukd allow better control over dependencies
and allow me to avoid the cgo
I recommend the fasthttp package. I have implemented an HTTP forwarding
proxy in Go and use in production with high traffic (~40 rpm).

Hi,
Thanks, I have created these two proxy using the httputil. How can i send
JSON request body from proxyA to proxyB.
Any help or idea?
ProxyA:
const (
ServerB = ""
Port = ""
)
func main() {
// start server
http.HandleFunc("/", proxyPass)
log.Fatal(http.ListenAndServe(":" + Port,
After working with a few more-or-less OAuth2 APIs lately, I would like to
propose slightly extending the API footprint of the oauth2 library.
By doing so I expect that the amount of userland/provider-specific code can
be reduced- both inside oauth2 and outside in realworld applications. Some

Hi,
Now I've finished the package types2 for typecheck logic, and continue the
journey to next step: IR generation(directory: cmd/compile/internal/ir/).
It seems the ir package is a new abstract layer created during the refactor
process of types2, and it's main purpose is to translate the AST

I think what is going on here is that it is wrong to say that `(*observer)`
creates a copy:

That variable is addressable and

Hi all,
I stumbled upon this strange looking piece of code [1]. I thought it
dereferences the pointer, creating a copy of the mutex, and then calls
RLock() on the copy (i.e. a nop). But it does not work this way. I
experimented with it [2] and [3] and it looks like my reading of code is
wrong.

Ah well, if it's just for fun then please knock yourself out, but don't be
surprised if compiling old code on new compilers turns up problems like
this. My suggestion is firing up a VM containing a Linux distribution of
similar vintage (say Ubuntu 12.04) and compile inside that.

This is not something that I've thought about before, but the behaviour
of math.Max when only one of its arguments is NaN does not agree with
the C convention or the IEEE-754 standard behaviour for max (5.3.1 p19

Could you describe what platform you are trying to build on?
Also, could you explain why you need to build such an ancient version?
There may be a better solution to whatever you're trying to do.

I tried to install go1.1.2 on my system, without success.
I encountered the following problems:
1. There is no binary release
2. Compilation fails due to warnings:

Hi,
I have to implement an HTTP forwarding proxy in Go which can be used in
production and need advice from Go experts.
Any advice like which Go library is best to use and other things to take
not of when implementing it.
