post <- builder ~ `plan9-arm`

The one remaining plan9 builder is failing a significant fraction of build attempts.
Many of the failures follow specific known patterns (notably #49337, #46526, and #41952). However, many do not.

@millerresearch, @0intro, @fhs: is there someone who can investigate these failures and bring the plan9 port back up to par? With the 0intro builders missing (#49327, #49328), there is no longer any plan9 builder consistently passing tests.

For most of plan9-arm failures, the cause is filesystem flakiness on the builder machines (a cluster of 3 x raspberry pi 4). I've just reconfigured the build script to stop using ramfs (which has a locking bug) for /tmp, and stop using the ad hoc directory cache (which still seems to have some flaws). This should bypass most of the failures but will make the test suite a lot slower to run (by go.17 it had already regressed to about 2 hours even with these filesystem tweaks).

There are some other flakes of the "shouldn't be possible" variety, which are are rare and perplexing and impossible to replicate. They are occurring in general go runtime code, not specific to plan 9. There's a slight whiff of possible memory cache coherence trouble in some of these:
marked free object in span
attempt to clean non-empty span set
unexpected waitm - semaphore out of sync
runtime: cannot allocate memory
not inlined: unknown reason

It would be good to have a server-class ARM platform capable of running plan 9 as a more reliable builder. I don't know of one.

Change https://golang.org/cl/362975 mentions this issue: dashboard: omit the website repo on plan9

gopherbot pushed a commit to golang/build that referenced this issue Nov 11, 2021
The plan9 builders have relatively slow filesystems, and the website
repo is relatively filesystem-intensive — many of its tests walk and
process large trees of website content.

Instead of trying to precisely tune the x/website tests to pass on the
plan9 builders, let's skip this repo on them.

For golang/go#49338.

Many of the failure modes seem to have cleared up around 11 Nov.; it's not clear to me what fixed them.

One of the failures visible on the dashboard today is #49653; the other is the marked free object in span failure mode.

Change https://golang.org/cl/369018 mentions this issue: src/cmd/go/internal/work: lock Builder output mutex consistently

gopherbot pushed a commit that referenced this issue Dec 6, 2021
To prevent interleaving of output when 'go build' compiles several
packages in parallel, the output mutex in the Builder struct must
be locked around any calls to Builder.Print which could generate
arbitrary amounts of text (ie more than is guaranteed to be written
atomically to a pipe).

Fixes #49987
For #49338
