core: compile failures due to SSA race condition #4206

scottfeldman · 2024-03-25T18:45:54Z

Several folks on the Slack TinyGo channel reported in-frequent compile failures with 0.31.2.

Here's some I've captured in my build logs. I would estimate it happens 1/40 compiles. A re-compile is the work-around.

scottfeldman · 2024-03-26T16:41:13Z

I tried reproducing by calling TinyGo build in a loop, but no luck so far. It's gone over 600 iterations. I'll keep trying. The suggestion was to restrict TinyGo build to one CPU using taskset -c 0 tinygo build ..., but right now I'm just trying to get it to fail in a loop without taskset...

However, just in my normal GitHub workflow build, I did get another one:

#14 171.4 /usr/local/bin/tinygo build -target wioterminal -o ../../skeleton-wioterminal.uf2 -stack-size 8kb -size short /tmp/build-770892309.go
#14 174.9 2024/03/26 05:37:41 Error generating UF2s: exit status 1: Basic Block in function '(*github.com/***/dean.mutex).setlock' does not have terminator!
#14 174.9 label %gep.next
#14 174.9 error: verification error after compiling package command-line-arguments

I've noticed that all of the failures I've posted to this Issue are with -target=wioterminal, but I'm pretty sure I've seen if fail with other targets.

dkegel-fastly · 2024-03-29T21:05:58Z

It just hit me. Oddly, this was just after I did "brew upgrade".

Here's the error:

 tinygo: "Basic Block in function '(*math/big.nat).sticky' does not have terminator!\nlabel %entry\nBasic Block in function '(*math/big.nat).sticky' does not have terminator!\nlabel %entry\nerror: verification error after compiling package crypto/ecdsa\n": exit status 1

And here's the program I was compiling:

package main

import (
        "context"
        "fmt"

        "github.com/fastly/compute-sdk-go/fsthttp"
)

func main() {
        fsthttp.ServeFunc(func(ctx context.Context, w fsthttp.ResponseWriter, r *fsthttp.Request) {
                fmt.Fprintf(w, "Hello, %s!\n", r.RemoteAddr)
        })
}

Options included -opt=2 -target=wasi -gc=leaking and probably a few others.

scottfeldman · 2024-04-04T19:22:34Z

I hit it again today, this time on -target nano-rp2040 and with a different failure signature:

deadprogram · 2024-04-05T17:17:33Z

@aykevl any clues on this?

dkegel-fastly · 2024-04-05T17:38:43Z

I think dgryski suggested building with race detection on to see if that catches anything, and ayke had a couple suggestions on top of that: https://gophers.slack.com/archives/CN4R2DQV7/p1711749220916969

aykevl · 2024-04-08T11:49:37Z

Is there anybody able to provide a reproducer?

If you try to reproduce, here are a few ways to increase success:

Remove cached files between runs: rm ~/.cache/tinygo/obj-* (or tinygo clean but that's slower)
Do it in a loop (something like while true; do tinygo xxx; rm ~/.cache/tinygo/obj-*; done )
Don't change the number of cores, use all of the available ones. It's unlikely to reproduce when you limit tinygo to a single core (there wouldn't be a race condition on a single core).

deadprogram · 2024-04-08T11:52:47Z

Pretty sure I have seen this occur in CI builds as well.

I've added this step to my project's CI, after each TinyGo build cmd. So far I haven't seen anything, but I'll keep an eye on it.

scottfeldman · 2024-04-10T08:29:24Z

Hit another one tonight. And this is with rm .cache files after each TinyGo build per @aykevl's suggestion.

I am also seeing this

rockwotj · 2024-04-16T14:25:54Z

Duplicate of #3062?

dkegel-fastly · 2024-04-16T14:48:55Z

I will admit, this bug is remarkably similar to #4206

rockwotj · 2024-04-16T14:51:53Z

Ugh clearly haven't had my coffee yet - I copied the wrong issue number: #3062

Tinygo has some race/bugs where it fails due to tinygo-org/tinygo#4206 Add retries to mitigate. Signed-off-by: Tyler Rockwood <[email protected]>

aykevl · 2024-04-17T15:18:36Z

Yes it is similar in the sense that it is a race of some sort, but for #3062 we found a specific cause that we fixed in #3920. The current issue seems to be a different problem.

aykevl · 2024-04-17T15:27:52Z

To all the people reporting crashes: please provide a reproducer. I can't debug this without a reproducer, I have to see the crash happening on my own system. Getting more crash logs is near-useless, what I need is:

the source code (enough that I can build the exact same binary you're building)
the full compiler command, with all flags
the environment (OS, architecture, TinyGo version, etc) - use tinygo version.

aykevl · 2024-04-17T17:33:55Z

For the record, apparently this command failed at some point in CI (CC @dkegel-fastly):

tinygo build -size short -o test.hex -target=nano-rp2040         examples/rtcinterrupt

EDIT: this doesn't seem to reproduce on my system even after many attempts. Or maybe I should leave it to run for a longer time...

rockwotj · 2024-04-19T02:58:55Z

On the note of it being rare, I have seen it crop up on the order of ~1/10000 builds based on our CI stats.

deadprogram · 2024-04-24T13:59:13Z

I think the race condition pretty consistently appears in this check https://github.com/tinygo-org/tinygo/blob/dev/builder/build.go#L384-L386

Is it perhaps because the IR for pkg.ImportPath is not yet fully written when some other package also needs it as a dependency, and then also tries to write it?

aykevl · 2024-04-27T07:56:22Z

I've found a reliable reproducer! Run this in the fish shell in ./tests/os/smoke:

while true; rm ~/.cache/tinygo/pkg-*; tinygo test -c -target=pybadge; end

I think the race condition pretty consistently appears in this check https://github.com/tinygo-org/tinygo/blob/dev/builder/build.go#L384-L386

VerifyModule probably isn't the problem (in fact it should only read the module), most likely the problem is introduced earlier and only detected when verifying the module.

Found a race condition!
~~I don't know whether it's the big one~~ (edit: it's not) but it's a race so should be fixed: #4243

aykevl · 2024-04-27T09:08:35Z

So now I have a reliable reproducer, I found that the bug does not reproduce with -race 😭 only without that flag.
My next suspect is golang.org/x/tools so I'm testing an older version now to see whether it still occurs there.

aykevl · 2024-04-27T10:27:21Z

golang.org/x/tools seems to be the culprit, I'm bisecting between v0.14.0 and v0.15.0.

aykevl · 2024-04-27T10:53:41Z

I think it's this commit: golang/tools@75ff53b
Almost done bisecting, I'll let this run a while to be sure (it may take a while for the bug to appear).

Here is the upstream bug report: golang/go#67079

Here is our latest example of this bug doing its thing 🐛
https://github.com/tinygo-org/tinygo/actions/runs/8880740326/job/24381494362?pr=4252#step:14:28

the go tools change in question is https://go-review.googlesource.com/c/tools/+/538358/7

aykevl · 2024-05-13T18:03:34Z

Currently down to this set of packages that when compiled together leads to a race:

source_filename = "internal/testlog"
source_filename = "encoding"
source_filename = "sync"
source_filename = "context"
source_filename = "time"

Interestingly, this doesn't seem to include any reflection? (Though I haven't investigated the packages deeply).

(Still figuring stuff out, I plan on sharing my findings once I know exactly which packages are the culprit).

aykevl · 2024-06-05T12:13:40Z

Got a bit further, and managed to capture a race condition log. See the details over at golang/go#67079 (comment). Hopefully this is enough information for the Go developers to find the race.

aykevl · 2024-06-06T17:47:56Z

There is now a fix, only waiting to be merged: https://go-review.googlesource.com/c/tools/+/590815
(I didn't test the fix but I'm hopeful this will fix the race condition we've been seeing).

aykevl · 2024-06-12T10:12:37Z

New patch: https://go-review.googlesource.com/c/tools/+/591775

aykevl · 2024-06-12T10:51:01Z

Temporary fix (applying one of the upstream proposed patches): #4292

deadprogram · 2024-06-23T17:17:01Z

This was released with v0.32.0 so now closing. Thank you everyone!

This commit reverts commit 13a8eae. It appars that the race has been fixed by golang/tools@db513b091504, which we now use because it fixes another race condition as well. See: #4206
