unstable fingerprints for item_children - ICE on Rust 1.52.0 stable #85019

ohsayan · 2021-05-07T03:28:29Z

Code

Skytable is quite a large project and I'm trying to produce a MCVE as soon as I can.
You can find the relevant logs on our CI server: https://build.skytable.io/skytable/skytable/98/1/3. From what I can see, this only happens on 1.52.0 and I'm supposing this is a regression from stable. For what it's worth, our CI server is running on an M1 Chip (aarch64-apple-darwin). From the backtrace it seems like the compiler panics while trying to build the sky-bench component or libsky (which is the smallest part of the project)

Update [August-08-2021]: After upgrading to 1.54, ICEs continue to appear. See this comment

Update [August-09-2021] @Aaron1011 has investigated this extensively. Please refer to this comment and see the log here

Can confirm this doesn't happen on 1.51.0 stable

hellow554 · 2021-05-07T07:16:26Z

I can't reproduce it on linux neither with cargo build nor with cargo test. Is it an platform specific problem?

ohsayan · 2021-05-07T07:51:17Z

I can't reproduce it on linux neither with cargo build nor with cargo test. Is it an platform specific problem?

Neither can I repro on our Linux/macOS/Windows (Intel x86) machines

ohsayan · 2021-05-07T12:26:00Z

Our CI continues to reproduce this exact error in subsequent runs:

Oddly enough, it passes with: https://build.skytable.io/skytable/skytable/102/1/3 and fails right on the next ones. Since deps were upgraded, there were some changes to the target folder which I'm going to assume caused the build to pass. I'm making this assumption from the build log which shows 'fresh' for run 102, but doesn't on subsequent runs

ohsayan · 2021-05-09T02:34:05Z

We continue to reproduce this error; I'm creating a new storage pool for the CI runs to see if it helps; all relevant failure logs can be found here: https://build.skytable.io/skytable/skytable

Edit: By new storage pool I mean we're technically removing all the earlier cache
Update: After clearing the cache the build passes; seems like this is an issue with the target directory. I've kept the old cache just in case anyone would like to use it for debugging
Update: The build crashed right now; so it's clearly pre-existing compiled deps/resources that is causing problems (incremental compilation cache)

Mark-Simulacrum · 2021-05-09T02:54:41Z

Please see #84970 - you should likely be able to fix with CARGO_INCREMENTAL=0 for the time being.

Aaron1011 · 2021-05-09T21:41:58Z

This is fixed on the latest nightly

apiraino · 2021-05-12T07:09:36Z

We're going to remove the I-prioritize label, we think this (and related) issue are already being handled (Zulip thread) in the context of the general parent issue.

Removing the regression label since this occurred on earlier releases, it just didn't ICE (see #84970 for context).

seems like this is an issue with the target directory.

This might be the issue for me as well since this is occurring after moving a cached target directory (for CI purposes), although I have not tested whether this is the cause.

Aaron1011 · 2021-05-29T16:02:58Z

@Imberflur: Does this happen on CI, or are you able to consistently reproduce this locally?

I suspect that this will be fixed by #85153, since the global untracked state export_map is involved in computing item_children.

Imberflur · 2021-06-01T00:58:23Z

@Aaron1011 I'm not able to reproduce this locally

ohsayan · 2021-08-08T13:45:44Z

Update: Even after upgrading to 1.54 and clearing out older caches completely, we're seeing a number of ICEs:

Edit 1: Unless the cache is deleted after every run, we'd get an ICE
Edit 2: Also, we use caching everywhere, but the major source of ICEs are from the aarch64-apple-darwin target (maybe this needs more investigation; I'd be happy to share any additional information)

Aaron1011 · 2021-08-08T16:38:00Z

@ohsayan: Have you been able to reproduce the ICE on linux?

ohsayan · 2021-08-08T16:59:09Z

@ohsayan: Have you been able to reproduce the ICE on linux?

@Aaron1011 All our CI runners on Linux use caching, but none of them have shown any ICEs yet.

This issue isn't platform-specific after all. It occurs when the crate is rebuilt with the same target directory (set with CARGO_TARGET_DIR), but from a different source directory path. The M1 builder for skytable uses a shared target directory across different jobs, but each job gets a unique path for its clone of the repository.

Include (potentially remapped) working dir in crate hash Fixes rust-lang#85019 A `SourceFile` created during compilation may have a relative path (e.g. if rustc itself is invoked with a relative path). When we write out crate metadata, we convert all relative paths to absolute paths using the current working directory. However, the working directory is not included in the crate hash. This means that the crate metadata can change while the crate hash remains the same. Among other problems, this can cause a fingerprint mismatch ICE, since incremental compilation uses the crate metadata hash to determine if a foreign query is green. This commit moves the field holding the working directory from `Session` to `Options`, including it as part of the crate hash. cc `@ohsayan`
