Gitlab lyrebird build/run == error

с какого то момента после git pull перестали работать obfs4 мосты через lyrebird
причем я не настолько понимаю в git/go чтобы понять что сломалось

через obfs4proxy или “старый” lyrebird как и раньше без проблем.
вот так только собирается/запускается

C:\GitHub\lyrebird>git branch
* (HEAD detached from lyrebird-0.2.0)
  fix_dependency_redirect
  main

а вот это “последняя” версия == main

У меня работает последний main, но у меня собственный go.work с обновленными до последних версий локальными библиотеками с моими патчами и использую сишный тор, как более стабильный. Арти пока неюзабелен.

“C:\Program Files\Go\bin\go.exe” version
go version go1.22.4 windows/amd64

go get -u делаю после каждого git pull

но вот вместо make build делаю

env GOOS=windows GOARCH=amd64 CGO_ENABLED=0 go build -p 1 -a -ldflags “-s -w” -o lyrebird-64.exe

env GOOS=windows GOARCH=386 CGO_ENABLED=0 go build -p 1 -a -ldflags “-s -w” -o lyrebird-32.exe

раньше так собиралось/запускалось до “devel” версии (?!)

p.s. tor.exe как и tor на ubuntu так же матерятся на новые сборки. но там то мне пофиг. а тут народу выкладывал сборки АРТИ и не сразу заметил неработающие lyrebird что я так же собирал/выкладывал (у меня 4 таргета в РУСТ и несколько конфигов obfs4/lyrebird/snowflake/webtunnel/bridges/etc. все проверить руки не доходят)

пересобрал через make build
только версия в ошибке поменялась

2024-07-01T15:24:11Z WARN tor_ptmgr: PT for obfs4 failed to launch: Couldn’t parse IPC line “STATUS TYPE=version IMPLEMENTATION=“lyrebird” VERSION=“0.2.0-12-gf56896f””: no TRANSPORT in STATUS

У меня в каталоге go.work

go.exe build "-ldflags=-s -w" -trimpath -o lyrebird-client.exe gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/lyrebird/cmd/lyrebird

go get -u ./... и go get -u all я тоже делаю, но после этого надо патчить, библиотеки не стабильны и меняются API. Например на github.com/andybalholm/brotli v1.0.5 клиент не мог подключится. (Сейчас на 1.1.0 работает). Пробуйте на оригинальном go.mod собрать.

неа. то же самое у меня выдает
даже пытался через MSYS2 ucrt пересобрать

а можно как то сделать go get -u только для определенного git TAG ?
я вижу те же версии что в main но добавляется что то новое после
git switch --detach tags/lyrebird-0.2.0 --recurse-submodules

Да, например go get -u github.com/andybalholm/brotli@latest. После @ можно указать тег или ветку.

После всех махинаций можно прогнать go mod tidy для оптимизации go.mod.

What changed, after your git pull, is that lyrebird started reporting its version number to tor. The STATUS protocol that is used by pluggable transports to report their version number was recently re-specified in an incompatible way. It looks like an unanticipated bug that it would cause problems with already deployed versions of tor that interpreted STATUS messages according to the old specification. I left some comments on the bug tracker:

As a workaround, you can try removing the pt.ReportVersion calls from this commit: Report the lyrebird version to tor (f56896ff) · Commits · The Tor Project / Anti-censorship / Pluggable Transports / lyrebird · GitLab.

thanks. i am not programmist. only user
waiting for future fix
my build worked with

C:\GitHub\lyrebird>git branch
* (HEAD detached at lyrebird-0.2.0)
  fix_dependency_redirect
  main

@LeonMskRu I didn’t notice, at first, that you are using Arti, not C-tor. Apparently, using a new lyrebird with an old version of C-tor is only a warning, but in Arti it is an error that prevents the pluggable transport from running. I opened a new issue in Arti.

thanks.
ARTI error == yes

new TOR + any lyrebird OR obfs4proxy == strange things
i am dont make many tests and dont know tor.exe error dont same as ARTI

Lyrebird with Arti should start working again after this MR is merged:
