Description of problem:

While running go test with coverage tekton-cache is causing permission issue.
go coverage requires that files  inside the cache must have +x permissions but but default they just read permission only.

Workaround

Change the permission of cache dir before build

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

 
1. Install OSP Operator 1.20 or earlier
2. Create Pipeline
https://github.com/openshift-pipelines/tekton-caches/blob/272e490e9b1989ea463019ca70695c683379aa45/dev/examples/10_pipeline/00_pipeline-go.yaml
 
Point to note about this pipeline is build command. You must use this build command if using different pipeline
 

go test -v ./... --cover

 
 
3. Create Pipeline Run
https://github.com/openshift-pipelines/tekton-caches/blob/272e490e9b1989ea463019ca70695c683379aa45/dev/examples/20_pipelinerun/00_pipelinerun-go.yaml
 
Here we need to take note of golang image. golang version must be 1.25 or later. This issue was not there on earlier go version.
 
 
Pipeline Run should succeed without any issue. First time build do not involve caches.
 
4. Now Rerun same pipelinerun
 
This time cache will be downloaded so build will fail with some permission errors like

2025-09-05T11:43:30.678108604Z go tool covdata: fork/exec ../cache-workspace/cache/gocache/85/850f5a46643dc9e560c32596c9fc0ffba0db20f04682733af2d4aa80f2d73fdf-d/covdata: permission denied
 
This error indicates that build command was not able to execute the covdata which is required by --cover statement
 
 
Now Deploy the fix. 
Update cache step actions with

https://raw.githubusercontent.com/openshift-pipelines/tekton-caches/refs/heads/main/tekton/cache-upload.yaml 
 
 
Return the same pipeline once more.
This time again  cache will be used but issue must not surface. 
You may try trying the pipelinerun multiple times.
You may also try different combinations as per your test suits.
