github_repository_file keeps sending empty commits with the same commit message despite no changes to file content #689
Description
(I had already opened an issue about this in the old repo, but after it moved here, seems to have been lost...)
Terraform Version
Terraform v0.14.5
Affected Resource(s)
- github_repository_file
Terraform Configuration Files
resource "github_repository_file" "file" {
for_each = {
for x in flatten([
for name, repo in var.repos : [
for file in fileset("templates", "${repo.template}/**") : {
repo = name
file = trimprefix(file, "${repo.template}/")
template = repo.template
}
] if can(repo.template) && lookup(repo, "archived", false) == false
]) : "${x.repo}:${x.file}" => x
}
repository = each.value.repo
branch = github_branch_default.default[each.value.repo].branch
file = each.value.file
content = file("templates/${each.value.template}/${each.value.file}")
commit_message = "chore(template): update ${each.value.file}"
overwrite_on_create = true
depends_on = [
github_repository.repository
]
}Expected Behavior
Should not be sending empty commits with the file content not having changed!
Actual Behavior
when running terraform plan everything looks correct, and there is no indication that any modifications to the referenced files will be triggered, but when running terraform apply a whole bunch of empty commits are sent with the same commit message template
see this repo for a recent example: https://github.com/ahmadnassri/node-glob-promise/commits/master
all the commits starting with chore(template) are an example of this
I tried adding
lifecycle {
ignore_changes = [
commit_message
]
}but that simply re-uses whatever the previous commit message was for the file and commits anyways!
