Get tmp stuff in $GOTMPDIR instead of /tmp?

[per...@gmail.com]

I get a bloated /tmp-dir (in just a few days I get tens of thousands of folders named /tmp/go-build828718408 etc.) so I tried to set $GOTMPDIR, but nothing ends up there. (From what I understand of the documentation the purpose of GOTMPDIR is to move tmp stuff, see e.g. line 1471 of https://golang.org/src/cmd/go/alldocs.go?h=GOTMPDIR, or release notes of 1.10 https://golang.org/doc/go1.10).

Am I using things wrong?

$ go version
go version go1.12.6 linux/amd64

$ echo $GOTMPDIR
/tmp/go-builds

$ ls $GOTMPDIR
please-end-up-here.txt

$ go build/test/this/that/etc
[...]

$ ls $GOTMPDIR
please-end-up-here.txt



Kind regards,

Per the go-noob.

go build uses GOCACHE, not GOTMPDIR. See go help environment.

Sorry, i was wrong, those are supposed to be temporary files, and they
are going correctly to GOTMPDIR for me, not sure what your problem is.

That is odd in itself. The go-buildNNNNN directories should normally
be deleted when the go command completes. Are you routinely killing
your go commands before they complete and have a chance to remove the
temporary directory?

Setting GOTMPDIR should work. What shell are you using? Did you
"export GOTMPDIR"?

Note that, as mentioned above, an ordinary go build will create a
temporary directory in GOTMPDIR and then delete it. So it's normal to
not see anything there after the go command completes. You can verify
the directory it uses by running "go build -work" (in which case it
will not delete the temporary directory).

This is routinely happening to me too, on linux. My go commands are go build *.go

The left-over directories are empty

I'm on go1.12.5 linux/amd64

Well, that is ungood. And I don't see it myself. Can you figure out
a way to reproduce the problem?

The only weird thing I've done is some manual upgrade of go (Ubuntu had not gotten modules so I did some wget thing to get a newer version I think). I do go build in bash because the modules thing has broken VS Code (or I have a mismatch of VS Code plugins, etc. etc. -- all acceptable pains). I sometimes do go test but not that often. I'm working with go buffalo to make a web-thing, and I'm also working with sqlboiler.

Here are some environment details:
