I am facing a strange issue with git resource in chef. I am getting the UnresolvableGitReference error even though the repository and the tag exists.
compiled resource in the recipe:
git("/opt/some-repo") do
action [:sync]
retries 0
retry_delay 2
default_guard_interpreter :default
destination "/opt/some-repo"
enable_checkout true
revision "tags/v3.0.4"
remote "origin"
checkout_branch "deploy"
declared_type :git
cookbook_name :"some-cookbook"
recipe_name "install"
user "ubuntu"
repository "[email protected]:someUser/some-repo.git"
end
The instance can access the git repo and the reference.
git ls-remote '[email protected]:someUser/some-repo.git' 'tags/v3.0.4*' returns me the commit id.
The cookbook works fine in chef v11.8.2 however fails in chef v12.5.1
With the git resource you can use only the tag name 'v3.0.4'. If you need to specify that it is a tag, you can also use the full path: 'refs/tags/v3.0.4'.
This worked before because Chef 11 checks against the reference sufix:
found = refs.find { |m| m[1].end_with?(@new_resource.revision) }
But this can be problematic as you might imagine. I think 'tags/v3.0.4' to work was never an expected behavior.
Anyway, in Chef 12 the implementation has changed, and now searches by prefix, appending 'ref/tags/' and 'refs/heads/' to search for tags and branches respectively:
def find_revision(refs, revision, suffix="")
found = refs_search(refs, rev_match_pattern('refs/tags/', revision) + suffix)
found = refs_search(refs, rev_match_pattern('refs/heads/', revision) + suffix) if found.empty?
found = refs_search(refs, revision + suffix) if found.empty?
found
end
def rev_match_pattern(prefix, revision)
if revision.start_with?(prefix)
revision
else
prefix + revision
end
end
