Reopen in maintenance mode by tonistiigi · Pull Request #247 · pkg/errors

tonistiigi · 2026-03-26T22:52:36Z

Maintainers from @moby project can take over keeping this repo available in maintenance mode.

From README:

This package is in maintenance mode. New features that extend the scope of the package are not being accepted and should be implemented in other modules. Exceptions would be features that improve interoperability with the standard library's errors package when it receives new features, as pkg/errors should mostly be able to act as a drop-in replacement. Bug fixes and reports are welcome. CI will be maintained to make sure the package is tested against new versions of Go and Go linting tools.

Curious about these; were the tests wrong, or did behavior change between Go versions? (ISTR something changed in some of stdlib).

If it changed in Go, was that before, or after go1.20 (otherwise tests won't be valid with the minimum version specified in go.mod)

These tests were pre-gomod and expected checkout to be in GOPATH that is not a requirement anymore.

 package errors


I would squash the removal of the tags with the previous commits, but keep the removal of the Makefile in this one.

These are opinionated changes, while the first commit is purely making the linter and test pass with the recent version of Go without changing anything about the code. Moved the makefile away.

This commit starts the work of picking up maintenance; I think it would make sense to move this (and forward) separate.

(Steps before this were just setting the baseline)

Moved to last

bench_test.go

 // GlobalE is an exported global to store the result of benchmark results,
 // preventing the compiler from optimising the benchmark functions away.
-var GlobalE interface{}
+var GlobalE any


any was added in go1.18, and the module already had go1.20 as minimum; I think we can squash this one with the "fix linting" commit, or move it before the addition of the go1.26 features.

modernize is not same as lint. These changes make the code use the latest conventions but are not required for the code to work properly and lint pass in recent Go.

Perhaps add main to the list, so that we can rename the default branch.

This commit could also be put before the go1.26 feature commit, making it part of the "baseline".

Renaming branches does not seem compliant with maintenance mode.

Left some comments (sorry I reviewed per commit, so some got superseded in later commits).

Overall looks good; some things I think we should do;

Some commits can be squashed (see my comments)
Move the fix linting, remove old CI files, and general cleanups first
Move the go1.26 enhancement as a follow-up pull-request

I’m not sure the stacktrace feature is even useful. Most people tend to declare their errors at the top level, where the stacktrace ends up being _init anyways, and not anything useful pointing to where the error originated…

tonistiigi · 2026-03-30T05:56:41Z

@puellanivis There is no obligation to use this package. This package works well with typed/static/chained errors; you add the stack trace to the return path, not to the definition path, if you use static errors.

Fix gofmt formatting, simplify code patterns flagged by gocritic/staticcheck/revive, update test path expectations to not assume GOPATH layout. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>

Remove go1.13 build constraints from unwrap functions since go.mod minimum is go1.20. Rename go113.go and go113_test.go to unwrap.go and unwrap_test.go. Delete Makefile as build/test/lint are now handled by Docker Bake targets. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>
