Self-built buck2 cannot rebuild buck2 again #971
Description
I might be holding something wrong, but as of the latest tip of main, try this:
./bootstrap/reindeer --third-party-dir shim/third-party/rust buckify
./bootstrap/buck2 build --out buck-out/buck2-stage1.exe //:buck2
./bootstrap/buck2 clean ; ./bootstrap/buck2 killall ; rm -rf buck-out/v2There's only buck2-stage1.exe available:
austin@GANON:~/src/buck2.jj$ ls buck-out
buck2-stage1.exe
Now try to rebuild a stage2 and complete the cycle:
austin@GANON:~/src/buck2.jj$ ./buck-out/buck2-stage1.exe build --out buck-out/buck2-stage2.exe //:buck2
Starting new buck2 daemon...
Connected to new buck2 daemon.

[ble: exit 3]
I'm fairly confused by this error. is_deferrable was removed recently, after the last pre-release upload (which is where the dotslash binaries come from.)
But the resulting buck2-stage1.exe should be using a compatible prelude, shouldn't it? The error here seems to indicate that buck2-stage1.exe is using the prelude that is shipped with ./bootstrap/buck2, somehow. How is this possible?
