ICE: "no entry found for key" while building stage0 tools

Checked out the latest version of the compiler today to write a patch, but ran into an ICE when doing py check. I haven't changed anything recently, so not sure what's causing this.

Compiling the compiler at commit 13edc17

It looks like old incremental compilation data is getting reused. I believe that this should be fixed by #86641.

In the meantime, running ./x.py clean should fix this.

Duplicate of #76720.

This is not actually a duplicate. This happens in stage0, not stage1, so it's not related to sharing the version string between different dev builds. It might be the case that we're not clearing the cache when we update the beta compiler, but that will have a different fix and should be tracked separately.

(It happened to me this morning)

@cjgillot

The strange thing to me is that we shouldn't need to clear the stage0 cache - beta should just be ignoring incremental artifacts that don't match the version hash. @cjgillot @michaelwoerister do you know what could be going on here?

I do think this is a purely incremental bug because rm -r build/x86_64-unknown-linux-gnu/stage0-tools/x86_64-unknown-linux-gnu/release/incremental/ fixed the issue, I didn't need to clear any .rmeta files.

@Mark-Simulacrum

cc @Mark-Simulacrum this is likely a real regression that's going to end up in 1.71 - unclear which PR caused it so probably not much to do at this point but thought you'd want to know since the release is going out soon

Tagging for prioritization. It's not clear to me how impactful this is; I know I've seen and heard about other(?) incremental problems in 1.70 as well -- I think there's been some issues filed. Unfortunately I don't think we've found solutions that eliminate the problem at the root so just need to hope we don't introduce new ones :/

michaelwoerister unfortunately I deleted the directory and didn't record the steps to reproduce the error :( but BoxyUwU managed to reproduce a similar error by checking out the first commit after the 1.70 version bump, running x build rustdoc, then checking out the latest commit and rebuilding - maybe that will work here?

I wrote a script based on this statement; intending to run a git bisect --no-checkout, but it didn't reproduce for me on macOS x86_64.

#!/usr/bin/env bash

set -e

./x.py clean
git checkout $(git rev-list 1.70.0..master -n 1)
./x.py build --stage 1 rustdoc
git checkout $BISECT_HEAD
./x.py build --stage 1 rustdoc

yes, sorry - there are several issues mixed into the history here and not all of them are the same. the one that's going to land in 1.71 is #112700, which no one has been able to reliably reproduce. the one boxy ran into was likely fixed by #109935 and no longer reproduces on master.

make sure that you do not rebase over any version bump. if the stage0 compiler changes, your testing is invalid (because they just won't read the same metadata files).

If all issues mixed in here are tracked elsewhere cleanly, perhaps it makes sense to close this one?

Closing this as a duplicate of #108481 (which has been fixed by #109935).
