right.

indeed, after having tagged v1.4.3 with:

retract (
// v1.4.3 was tagged to retract v1.4.2
v1.4.3
// v1.4.2 was imported from phpdave11/gofpdf by mistake.
v1.4.2
)

everything worked as it should.

thanks a lot for the help.

['Jay Conrod' via golang-nuts]

As Dan mentioned, the version containing the retractions must be the
highest version, so you'd need to tag v1.4.3 or higher. If that version
retracts itself, it won't appear in the version list either.

thanks for the pointer to the tutorial.
I think I did apply all the expected operations on my repo:

- tagged a v0.4.1 version with the `retract v1.4.2` stanza:
  
https://github.com/go-pdf/fpdf/pull/10/files#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6
- waited for a minute or so and issued:

$> go list -versions -m
github.com/go-pdf/fpdf v0.1.0 v0.2.0 v0.3.0 v0.3.1 v0.4.0 v0.4.1 v1.4.2

I also requested v0.4.1 both on the pkg.go.dev site and explicitly in a
dummy module with `go get github.com/go-pdf/fpdf@v0.4.1`:

$> mkdir foo && cd ./foo
$> go mod init foo
$> go get -u -v github.com/go-pdf/fpdf@v0.4.1
github.com/go-pdf/fpdf

$> go get -u -v github.com/go-pdf/fpdf
go get: github.com/go-pdf/fpdf@v1.4.2: parsing go.mod:
module declares its path as: github.com/phpdave11/gofpdf
but was required as: github.com/go-pdf/fpdf


I am probably handing it the wrong way.

It looks to me like the retraction mechanism cannot be used here since
the retraction must be in a version number higher than the retracted
version, but here the author wants to not have a version v1. If
retraction were also based on time (maybe only for specific cases where
retracting by a v0 retraction).

Re: [go-nuts] how to purge invalid tags from GOPROXY?

['Jay Conrod' via golang-nuts]

Hi Sebastien, once a version is in proxy.golang.org, it usually can't be
removed. This is important to ensure that builds continue working when a
repository disappears upstream.

You may want to publish a new version with a retract directive in go.mod,
marking the earlier versions as invalid. In Go 1.16 and higher, the go
command won't automatically upgrade to a retracted version. The version
containing the retractions may retract itself. Retract Module Versions
 is an
interactive tutorial explaining how to use this feature.

Even with retractions in place, you won't be able to reuse the old version
numbers. They'll be hidden, but still available to any users that depend on
them.

[go-nuts] how to purge invalid tags from GOPROXY?

[Sebastien Binet]

hi there,

I've forked a fork of a Go package (github.com/jung-kurt/gofpdf).
But as the modus operandi of such a thing is rather unwieldy in github
(PRs would always be created by default against the original package
instead of my fork), I've deleted the forked repo, created a new repo
with the same name and pushed the original git tree there.

so now, my PRs are, by default against my fork, which is great.

unfortunately, I've also decided that my fork would start at v0.1.0
(what would be the last commit from the old gofpdf package) while the
original package was at v1.4.2

and it seems GOPROXY cached it somehow:

$> docker run --rm -it golang
root@clrinfopc42:/go# cd src/
root@clrinfopc42:/go/src# mkdir foo
root@clrinfopc42:/go/src# cd foo/
root@clrinfopc42:/go/src/foo# go mod init foo
go: creating new go.mod: module foo
root@clrinfopc42:/go/src/foo# go version
go version go1.16.5 linux/amd64
root@clrinfopc42:/go/src/foo# cat >> go.mod

require github.com/go-pdf/fpdf v0.3.1
^C
root@clrinfopc42:/go/src/foo# cat >> main.go
package main

import _ "github.com/go-pdf/fpdf"

func main() {}
^C

of course, it works if I give the explicit new tag of go-pdf/fpdf:

[...]
go get: upgraded github.com/go-pdf/fpdf v0.3.1 => v0.4.0


any idea how one could purge the tags (coming from {jung-kurt,phpdave11}/gofpdf?
I understand that comes a bit at odds with the way the GOPROXY ledger is
supposed to work though...

any idea on how to work around that?
thanks.

cheers,
