In theory they should be created by make torbrowser-alpha and make torbrowser-alpha-desktop (unless the base-browser changes in projects/release/config broke that). But not if you run make torbrowser-alpha-linux-x86_64, make torbrowser-alpha-windows-x86_64, etc separately.
hmm, IIRC I first did a a make torbrowser-alpha-linux-x86_64 for testing, and then deleted the alpha/unsigned/12.0a1 directory before doing a full build (or something similar)
So I removed my 12.0a1 output dir entirely, and did make torbrowser-alpha-desktop and src tarball was not generated, and it does not exist in the out/browser dir.
I'll try nuking out/browser entirely next and see what happens with a full build.
tor-browser-build/out/firefox/src-firefox-tor-browser-91.12.0esr-12.0-1-build2.tar.xz is generated for me but it is never placed alpha/unsigned/12.0a1-build1
tor-browser-build/out/firefox/src-firefox-tor-browser-91.12.0esr-12.0-1-build2.tar.xz is generated for me but it is never placed alpha/unsigned/12.0a1-build1
Ah, so that's an issue introduced in
70dc7d9f. In projects/release/build
we're still using var/torbrowser-src but it was renamed to
var/browser-src.
