Hello all!
I'm trying to read json objects from a named pipe. The pipe will be
filled intermittently by bash scripts. After the Decode() of the first
object, any more calls to Decode() will return EOF. This seems proper
since the script has completed, but once it errors with EOF, there doesn
Why do you use a json.Decoder? It seems as reading
everything (io.ReadAll) until EOF and json.Unmarshal'ling
would be a cleaner/simpler solution?

It is good practice to use test lang/tools/libs/etc different from what you
are using in your actual code.
If the author has meant for the httptest package as general purpose HTTP
testing library, then, I will argue that such defaults are incorrect. It is
incorrect even if the intended purpose
And so: https://github.com/golang/go/issues/63589

It is not "meant for tests internal to the http package". It's meant for
tests of users of the `net/http` package. That is, implementations of the
`http.Handler` interface.
In the context of the standard library, that is what "general purpose HTTP
testing" means.

I was thinking partial reads could be an issue and the Decoder seemed to do
the initial checking for me. Would the ReadAll() be able to recover from
EOF state?

Sorry I wasn't clear. The static libraries are in a subdirectory because
the user should not care and these libraries are effectively third party
code.
This declares the generic code available everywhere:
https://github.com/periph/d2xx/blob/main/d2xx.go
One set of files declare the import that is
Are you sure that the writer isn't closing the named pipe between writing
JSON objects? If necessary you can check this with strace.
I'm pretty sure you'll get an EOF in the *reader* when the *writer* closes
from their side. You can demonstrate this with the shell:
(In terminal 1)
mkfifo /tmp/f

In what regards are "partial reads" less well covered by io.ReadAll
than via json.Decoder?

Actually, you were totally clear. Sorry if my comment didn't ma
yes, thanks
I updated to the latest go and no longer get the error

Circling back to this, because it came up today again.
Here's the generic function I want to write. It comes up in a lot of
function composition, which in turn comes up in a lot of interface adapters
and such:
func maybeAssign[T any](dst *T, src T, name string) {
if *dst != nil { // any can't
I'd happy with
if val { ... }
and
if !val { ... }
Instead of comparing val with an explicit zero but don't feel strongly about
this.
