commit 381cfa494305a29eed29c54255d4395dbfc66ab0
Author: Filip Kobierski <fkobi@pm.me>
Date:   Thu Dec 26 20:31:09 2024 +0100

    net-p2p/syncthing: add 1.29.5 with improved ebuild

    changes, from top to bottom:
    - do not rename distfile
    - move project primary license to be the first
    - made RDEPEND more readable
    - updated DOCS
    - removed race patch
    - added loops to shorten the ebuild in src_{prepare,install}
    - swap $(usex a b "") to $(usev a b)
    - use brace expansion instead of for loop for installing tools
    - swap "syncthing" to ${PN} where it makes sense

It doesn't say *why*, though (please say that in future -- if you dropped it because it doesn't apply anymore and you don't see why it was there, say that in the commit message). 

At https://github.com/gentoo/gentoo/pull/39851#issue-2760089746, it says:
> @mschiff could you please explain what is the tests_race patch for?
> The patch does not apply as upstream changed the build script.

I'm also surprised that neither of you hit it, because it should happen (but maybe it doesn't) with PIE, which we do in:

go-module_src_unpack() {
        if use amd64 || use arm || use arm64 ||
                ( use ppc64 && [[ $(tc-endian) == "little" ]] ) || use s390 || use x86; then
                        GOFLAGS="-buildmode=pie ${GOFLAGS}"

Comment 4 Filip Kobierski 2025-05-05 08:07:31 UTC
I see that in the build.go "-race" is mentioned twice.
Since we target PIE, which conflicts with that flag, maybe it would be better to have a sed 's/-race//g' instead of the patch?

> > Do we still need it?
I was hoping for an answer before it gets merged.

Also Sam, could you please edit the title to contain both flags?
Like "${P} fails tests: -buildmode=pie conflicts with -race".

(In reply to Filip Kobierski from comment #4)
> I see that in the build.go "-race" is mentioned twice.

I'm still curious as to how you can't hit it -- do tests really pass for you?

> Since we target PIE, which conflicts with that flag, maybe it would be
> better to have a sed 's/-race//g' instead of the patch?

It's fine with me as long as people use qa-sed to notice if it stops applying.

I don't blame you ;)

Sure.
