Action is not detecting some violations

[sk-]

Since a couple of weeks we have been seeing repeatedly that the action does not report some violations while there are some in the code.

$ golangci-lint --version
golangci-lint has version 1.46.2 built from a333689 on 2022-05-17T06:05:08Z

We event tested it running with no cache and the issue still persists? Do you have any idea?

In case it works the troubleshoot, the last error that was not detected was:

unexported-naming: the symbol ID is local, its name should start with a lowercase letter (revive)

We are using the following configuration:

Similar issue for me. If I run golangci-lintlocally, it reports the following errors:

scripts/sync_legacy_plans.go:20:2  staticcheck  SA1019: "io/ioutil" has been deprecated since Go 1.16: As of Go 1.16, the same functionality is now provided by package io or package os, and those implementations should be preferred in new code. See the specific function documentation for details.

However, the GitHub Action is NOT detecting these violations.

Both my local and GH actions are using the v1.49.0 of of golangci-lint.

[sk-]

@ldez what further information is required?

[ldez]

it can be a side effect of cache, so you have to disable the internal action cache.

[sk-]

@ldez we did disable the cache and the error still persists

We event tested it running with no cache and the issue still persists

[aldrin-coexservices]

I am encountering the same issue. Anyone has fix on this one?

[HenryNguyen5]

Ran into the same issue, even when disabling caching completely, I still am missing violations that are shown on local runs.

I even ran just the raw bin, with a mostly clean env, CI is still missing violations.

[HenryNguyen5]

My issue ended up stemming from compilation errors that were silently ignored during the execution on the lint action. Running a go build ./... beforehand caught some compilation errors i was hitting from missing a file dep in test files. Once that was resolved, golangci-lint is working fine now :)

According to https://github.com/orgs/community/discussions/26680, you can only have 10 warnings or errors per step, and 50 per job which feels extremely low and arbitrary. I can understand this being used to make sure other annotations from other steps don't get lost in the noise. Unfortunately, this breaks workflows which are intending to post warning annotations to specific lines in files, such as to indicate the results of static analysis checkers.

There is no user interface feedback indicating that warnings are being hidden, nor documentation about this at https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#setting-a-warning-message, so it just makes it look like the feature is broken.

In my case, I think that's ☝️ what prevents all the errors showing up in the GitHub UI. The workflow summary UI only reports 10 errors but the the CLI output in the job / step logs reports 24 lines of errors. This might be a different problem than was reported by the OP.

Hello,

I added a new option annotations, which may be useful to some of you.

I added this option for several reasons:

• The number of annotations is limited.
• Some people don't want to use annotations and just want the classic colored-line-number format.

If you set annotations to false, the output format(s) will follow the golangci-lint configuration file (or CLI flags from args) and use the same default as golangci-lint (i.e. colored-line-number).
