Hello, compiling a24 I get

error: failed to parse manifest at /home/svenstaro/src/0ad/libraries/source/spidermonkey/mozjs-78.6.0/Cargo.toml

Caused by:

dependency (nix) specification is ambiguous. Only one of branch, tag or rev is allowed.

upon simply running ./update-workspaces.sh.

Full log attached.

Hi Sven,

This appears to be caused by a change in rust 1.50 (released 10 days ago) that our dependency spidermonkey 78 fell afoul of.

At this time we are recommending that linux repo maintainers apply the following upstream patch to our bundled spidermonkey source: ​https://hg.mozilla.org/releases/mozilla-esr78/rev/0e8f444683cb

Our apologies for not catching this in time for our A24 release.
